CORRELATION
To be of maximum value laboratory test results
must be rapid, reliable, reproducible both in the
same laboratory and from laboratory to laboratory
and must correlate with actual service performance.
The standard methods of test when used with the
Launder-Ometer provide such results.
WHAT IT IS AND WHAT IT DOES
INSURES BETTER PRODUCTS
In the manufacture, sale and purchase of prac-
tically all textiles, changes in color and dimensions
due to washing or dry cleaning are all important
factors. More and more the general public as well
as industrial-and governmental purchasing agen-
cies are insisting on merchandise which will with-
stand multiple launderings or dry cleanings without
the loss or change of color to such a degree as to
render the article unserviceable.
The Launder-Ometer quickly provides all con-
cerned with such information in advance without
the necessity of waiting for service reports after the
merchandise has been sold.
PRODUCT DEVELOPMENT
Dependable advance knowledge of colorfastness
to washing or dry cleaning of a new shade or prod-
uct under the actual method by which it will be
processed is of invaluable aid to the manufacturer.
In selecting the dyestuffs to produce a new shade or
to improve a standard product it is important to
determine the colorfastness to laundering and dry
cleaning of the product produced under the method
of application that will be actually utilized.
While each of a group of dyestuffs may have a
particular colorfastness rating when applied singly
under one method of application it is important to
know that the shade resulting from the combination
and Method of Prepare will have the desired color-
fastness- and will not fade or go off tone after mul-
tiple launderings or dry cleanings. Such informa-
tion can easily be determined by a short test in the
Launder-Ometer in advance of production.
QUALITY CONTROL
By providing information on the loss of color
that will be encountered in five commercial laun-
derings or home washings in one 45-minute test
the Launder-Ometer is effectively used as a control
on production. Periodic sampling of production
will quickly detect poor penetration or other mal-
functions in processing and permit immediate cor-
rection before large quantities of materials are
processed and leave the mill.
BUILDS REPUTATIONS
In an enviable position indeed is the company
or product whose name is synonymous. with qual-
ity at the consumer level. Advertising and sales
promotion can create an interest and put a com-
pany name or product over initially but quality of
merchandise is necessary to build and sustain a
reputation. Any testing program which determines
the quality of products before production is started
and again checks the finished product before ship-
ment is fundamentally sound and such honest effort-----
will be rewarded with greater sales and increased
prestige. Many Launder-Ometer users have found
their competitive position so improved that public
announcements have been made and whole adver-
tising programs built around their guarantee of
quality based on the use of the Launder-Ometer.
INSURES ACCEPTANCE
The use of a Launder-Ometer provides the sup-
plier with advance information that material sup-
plied under contracts will meet acceptance require-
ments for colorfastness to washing since most
government and industrial specifications are based
on standard tests made in the Launder-Ometer.

WASHING TESTS
The Launder-Ometer is fundamentally a labora-
tory device for conducting washfastness tests and it
is for this purpose it finds its greatest usefulness.
A complete description of the various standard and
accelerated colorfastness to commercial laundering
and home washing tests will be found in the cur-
rent Year Book and Technical Manual of the Amer-
ican Association of Textile Chemists and Colorists.
If not already available this book can be obtained
from The Secretary, A.A.T.C.C. National Head-
quarters, Lowell Textile Institute, Lowell, Mass.
For many years it was customary to make lab-
oratory washfastness tests in beakers. In attempting
to standardize such tests a systematic study was
made which led to the conclusion that the wide
variations in the results obtained by the beaker
method was due to both the lack of uniformity in
the apparatus and in the manner of conducting the
test. Temperatures varied considerably as did the
concentration of the wash solution which due to
evaporation was never constant. Removal of color
due to mechanical action as occurs in actual wash-
ing procedure was almost negligible and varied
with'the individual operator and from-time to time
with the same operator.
Through consolidation of the manifold efforts of
Messrs. L. C. Himebaugh, Hugh Christian, Wm.
D. Appel, L. A. Olney, W. C. Smith and the Atlas
Electric Devices Co., a standard laboratory wash-
ing machine, The Launder-Ometer, was developed.
As indicated by the official name plate, the
Launder-Ometer is the Standard Laboratory Wash-
ing Machine of the American Association of Tex-
tile Chemists and Colorists and is manufactured
and sold exclusively by the Atlas Electric Devices
Co.
The Launder-Ometer is free from the faults and
limitations encountered in the beaker tests and

makes possible strictly reproducible results. It has
been found to give the same results as commercial
and home washers in the removal of soil and for
this reason is successfully used for the evaluation
of soaps and detergents.
While the standard tests for washfastness utiliz-
ing the glass specimen jars provide a satisfactory
and reliable means of evaluating the comparative
fastness of dyed fabrics, it requires over two of
these tests to produce an effect similar to one com-
mercial laundering under today's conditions. In
1944 the A.A.T.C.C. Committee on Fastness to
Washing started work on the development of a new
accelerated washfastness test which would rapidly
in one short test produce the color destruction and
abrasive action of five average or typical commer-
cial or home launderings. This work sponsored by
the committee under the successive chairmanships
of C. W. Dorn, C. A. Seibert and C. A. Sylvester
was conducted jointly with the A.A.T.C.C. Re-
search Laboratories at Lowell, Mass.
Before a standard test method could be devel-
oped and adopted it was necessary to establish the
loss of color produced by multiple washings in an
average or typical commercial and home laundry.
To accomplish this samples of a large variety of
selected fabrics were submitted to multiple laun-
derings in a large number of laundries over
widely scattered geographical areas as well as to
multiple washings in several types of home wash-
ing equipment.
In developing the accelerated washfastness
tests which provide a means of approximating in
one 45-minute test the color destruction and abra-
sive action of five average commercial or home
launderings metal tubes were designed to replace
the glass jars used in the standard tests.
The metal tubes, 31/2" in diameter by 8" long
are mounted in the Launder-Ometer horizontally
at right angles to the shaft by means of an adapter
which is easily installed and removed. Mounted in
this fashion the test specimens are subject to a
forceful throw, a long slide and a strong impact.
The use of 100 stainless steel balls, as well as a
lower liquor volume ratio than that employed in
the standard wash tests in the glass jars, serves to
increase the abrasive action. While the method of
mounting the metal tubes and glass jars on the
rotor is different the total number of 20 which can
be accommodated at one time is the same.

The newer accelerated washfastness tests like
the standard wash tests are designed to cover the
ranges of severity comparable to those of general
washing practice which range from the very mild
wash at low temperatures to the very severe wash-
ing conditions at high temperatures with soda ash
and bleach. In general the trend is to classify tex-
tiles according to the general washing procedure
they will satisfactorily withstand or would nor-
mally be subjected to in actual use rather than
according to the fibre. Since the accelerated tests
can be used to predict five or multiples of five
average commercial or home launderings they are
widely used at the buyer level as a performance
requirement in purchasing specifications.
RESISTANCE TO BLEEDING
The Standard Colorfastness to Washing Test
Methods include the use of multifibre test cloth
for evaluating the degree of bleeding or staining
caused by contact of the test specimen with other
materials during washing.
mill practice of running such tests directly in the
fulling mill. After several years of work on the
part of the Research Committee of the A.A.T.C.C.
a method was devised based upon the use of the
Launder-Ometer which is equal to, if not better
than the mill method of determining fastness to
fulling of dyed material. The standard method
employing 3/4" stainless steel balls and standard
knit worsted tubing in the Launder-Ometer will
be found in the current yearbook of the A.A.T.C.C.
DETERGENCY TESTS
The Launder-Ometer is also very effectively used
in evaluating the cleansing power and deteriora-
tive action of soaps and detergents. The soil re-
moval from a specimen of a standard soiled fabric
washed under standard reproducible conditions in
the Launder-Ometer can be determined by photo-
electric reflectance measurements or by weighing.
Complete evaluation of a soap or detergent may
require the use of several standard soiled fabrics
each having different types of soil. Standard soiled
fabrics of more than one type are available com-
mercially but if these do not include all of the
its use, twenty comparative and simultaneous dye-
ings may be made under absolutely uniform con-
ditions of temperature and mechanical agitation
and under conditions which duplicate to a con-
siderable extent the actual process of leather dye-
ing. The Launder-Ometer may also be used for
certain comparative tanning experiments.
TEXTILE DYEING
Controlled temperatures up to boiling under
uniform conditions of agitation make the Launder-
Ometer ideal for conducting laboratory dyeing
tests on textiles. Since both the glass jars and
metal tubes are closed containers the effect of
oxidization due to contact with the air is elimi-
nated. For dyeing tests in glass jars many prefer
to substitute cellophane covered rubber stoppers
for the glass tops as they permit the use of more
pressure and give more assurance that the dye
liquor will not escape from the jar into the con-
stant temperature water bath.
DIMENSIONAL CHANGES
- While the use- of the Launder-Ometer for ihak---
ing laboratory shrinking tests has not received the
official recommendation of the American Associa-
tion of Textile Chemists and Colorists by the adop.
tion of a standard method, a number of Launder-
Ometer users find the device wholly satisfactory
for their particular requirements.
- -The --Launder=Oineter --furnishes - an excellent -- various type"-soil in-which there is-interest-the
means of determining in the laboratory the color- usual practice is for the laboratory to prepare ad-
fastness of textiles to dry cleaning. A standard
method for conducting the test and evaluation of
results will be found in the current Year Book
and Technical Manual of the American Associa-
tion of Textile Chemists and Colorists. Likewise
the Launder-Ometer is widely used by both manu-
facturers and users in the evaluation of dry clean-
ing fluids and detergents.
COLORFASTNESS TO FULLING
For a long time the generally accepted opinion
was that no laboratory test could be devised that
would equal in practical value or simplicity the
ditional standard soiled fabrics to meet their own
requirements. In addition to soil removal from
the standard soiled fabric the use of a piece of
white or multifibre test cloth in the test permits
the evaluation of the redeposition of soil by the
soap or detergent.
LEATHER DYEING
The Launder-Ometer furnishes a unique and
ideal piece of apparatus for making laboratory
leather dyeing tests. In laboratories or tanneries,
particularly where dye tests are made, the Laun-
der-Ometer will be found of great value. Through
GENERAL LABORATORY USE
There are many laboratory tests and experi-
ments requiring the treatment of materials with
liquids under uniform conditions of agitation and
temperature. For such work the Launder-Ometer
is particularly well adapted and will be found of
considerable value.

THE LAUNDER-OMETER
MECHANICAL DETAILS
The Launder-Ometer is a self-contained electri.
cally operated unit of all-metal construction de-
signed to give years of dependable trouble-free
service. Occupying a floor area of 28 inches by
64 inches it has a height of 52 inches to the top of
the control cabinet, with a net weight of 375
pounds and a domestic shipping weight of 525
pounds. The Launder-Ometer is shipped com-
pletely assembled ready to connect to the elec-
tric power, water supply, drain and steam or gas
lines according to the heating medium employed.
FRAME
The machine is built within and is rigidly sup-
ported by a welded angle iron frame finished in
dark green lacquer. The four legs are equipped
with gliders.
WATER BATH
A stainless steel tank or reservoir is employed
to contain the constant temperature water bath
through which the specimen containers are ro-
tated during the test. This tank is rectangularly
shaped at the top, rounded at the bottom and has
a capacity of approximately 15 gallons when
filled to the water line. This depth of water per-
mits one row of specimen containers to be out
of the water when they are stopped at the upper
point of rotation at which position they are readily
accessible for either opening of the containers, for
the addition of solutions or for the removal of the
containers from the rotor without the necessity of
draining the tank. All models except the automatic
gas type are supplied with the tank insulated by
one-half inch of corrugated asbestos which is cov-
ered by a protective metal jacket.
The tank is equipped with threaded flanges for
the drain, overflow drain, cold water inlet, hot
water inlet, outlet to pre-
heating loading table pump,
drain from overflow in pre-
heating loading table, ther-
mo-regulator element, indi-
cating thermometer element
and electric immersion heat-
ers or steam coil depending
upon the heating medium
employed.
If both hot and cold water
lines are available it is rec-
ommended that both be con-
nected to the Launder-Ome-
ter as filling the tank with
hot water when first starting
will materially reduce the
time required to bring the
water up to the desired tem-
perature and thus effect a
saving in electricity, gas or
steam. The hinged cover of
stainless steel is equipped
Standard Launder-Ometer with Preheating Loading Table.
with a plastic handle for ease of opening.
HEATING MEDIUM
All Launder-Ometers are equipped with a direct
reading dial type Thermo-regulator which
through suitable relays and control equipment
automatically maintains the constant temperature
water bath at the temperature selected by the op-
erator. This may vary from room temperature up
to boiling point depending upon the particular test
which is being utilized. Centigrade or Fahrenheit
scales are optional for both the Thermo-regulator
and the indicating thermometer.
Launder-Ometers are constructed to utilize elec-
tricity, steam or gas for heating the water bath.
Because of convenience and availability at all
times electricity is the most generally used. Where
greater flexibility and speed of heating is desired,
the model employing both steam coils and electric
immersion heaters is recommended. In this model
the two sources of heat may be used independently
or simultaneously as desired. Where steam is em-
ployed, low pressures are desirable, although the
Launder-Ometer can be supplied for operation on
pressures above 100 lbs. While steam is the most
economical method of heating its availability at all
times should be considered before the decision on
its use is made.

The automatic gas model can be supplied for op-
eration with natural, bottled or manufactured gas
or mixtures thereof. This model is equipped with
an automatic safety valve which shuts off the gas
to the burners if the pilot light flame is extin-
guished. Consideration of the gas heated model
should take into consideration any objection that
may exist to having a large open gas-burner in
operation in the laboratory. Type or Model desig-
nations, electrical, engineering and ordering data
will be found in the back pages of the catalog.
ROTOR
The jar holding rotor is a four-
sided corrosion resistant cast rotor,
each side having five openings into
which the pint-sized glass test jars fit.
Each side is equipped with four studs,
bronze spring clamps and wing nuts
which securely hold the jars in a ver-
tical position at right angles to the
side of the rotor on which they are
mounted. When all of the glass jars
are in place, there are four rows of
five jars each or a total of twenty.
DRIVING MECHANISM
The rotor is securely fastened to
a polished stainless steel shaft which
is rotated in self-aligning bronze
bearings and is driven at a uniform
rate of 42 r.p.m. by a fractional h.p.
motor through a gear reducer, pul-
leys, V belt and friction clutch. The
motor and gear reducer unit are
one individual specimen with the wash solution
and stainless steel or rubber balls so that up to
20 specimens may be tested at one time. Most
test methods require a specimen 2" x 4". The use
of multifibre test cloth for bleeding tests, the wash
solution and the number of stainless steel or rub-
ber balls utilized vary according to the test method
employed.
For the newer accelerated washfastness tests
metal tubes instead of glass jars are employed.
These tubes 31/2" in diameter and 8" long, are
held horizontally away from and at right angles
to the side of the rotor on which they are mounted
by adapter plates or castings. The adapter castings
which are easily inserted and removed are sup-
plied in two sizes, one holding two
and the other five- metal tubes.
rotor is in motion the jars or tubes
revolve radially with the rotor at a speed of ap-
proximately 42 r.p.m. through the constant tem-
perature water bath. While the speed of rotation
is constant the temperature of the water bath and
-- --- -mounted--on a -hinged base-with-the---the-duration-of-the-test will-vary -according-to-the-
weight of the unit providing the
proper tension on the V belt. A spring type safety
clutch is provided to permit stalling the rotor with-
out injury to the operator or the machine. As an
added protection to the operator a perforated
metal guard is fitted over the protruding end of
the drive unit.
SPECIMEN CONTAINERS
Pint sized glass specimen jars are employed in
the various standard washfastness tests which are
described in detail in the current Technical Man-
ual and Year Book of the American Association of
Textile Chemists and Colorists. Each jar contains

test method employed.
If the number of samples to be tested at any
one time is less than 20 so that the rotor is not
completely filled on all four sides with either glass
jars or metal tubes, the actual number of jars or
tubes being employed should be distributed as
nearly as possible on opposite sides of the rotor
so that the load is evenly distributed to avoid an
unbalanced condition.
The standard Launder-Ometer has a maximum
capacity of 20 glass jars, 20 metal tubes or a com-
bination of glass jars and metal tubes whose total
is 20.

THE LAUNDER-OMETER
The jars in the Preheating Loading Table are
rapidly brought up to and are automatically main-
tained at the temperature required in the test. This
is accomplished by circulating water from the
main tank or reservoir through the preheating
loading table. Like the main tank the Preheating
Loading Table is fabricated of stainless steel and
is insulated.

CONTROL CABINET
All Launder-Ometers are fully automatic and
are equipped with the control cabinet conveni-
ently located on the right-hand side of the machine
at the same working level as the top of the ma-
chine. The control panel contains all of the
switches, pilot lights, thermo-regulator and dial
type indicating thermometer. Directly in back of
the control panel are located the relays, fuses or
overload circuit breakers for the motor and heater
circuits. All switches and electrical appliances are
used and wired in a manner to provide complete
safety to the operator.
PREHEATING LOADING TABLE
The Preheating Loading Table is standard equip-
ment on all Launder-Ometers but may be omitted
if sufficient floor area, is not available. It is an
important adjunct, increasing the accuracy of the

be started at the same temperature.
Loading one set of specimens in the
Preheating Loading Table while an-
other series is being tested results in
a great saving of time and increased
output of the machine.
Convenient trays are provided for
holding the accessories (jar tops,
rubbers, balls, etc.). The. conveni-
ently located jar holder makes the
loading of the specimens, solution
and spheres as well as capping of
the jars rapid and positive.
At the end of the test the solution
can be quickly separated from the
specimens and spheres by merely
pouring the contents of the jar into
the built-in sink.

RESEARCH MODEL LAUNDER - OMETERS
In Research and Development work it is often
desirable to study the behavior of a new product
under widely different variations of the various
factors encountered in washfastness tests. In addi-
tion to variations in temperature these may include
size of the specimen, size and shape of the speci-
men container, number and size of the stainless
steel or rubber spheres, and the speed of rotation.
For this type of work we recommend the Re-
search Model Launder-Ometers which are avail-
able in two models, the L-1-Q and L-2-Q. These
two models differ only in the number of the var-
ious sized specimen containers that can be used
and. the method of their mounting on the jar
holding rotor. Included in the variety of specimen
containers that may be used in the Research Mod-
els are the one-pint glass jars utilized in the stand-
ard washfastness tests and the Metal Tubes em-
ployed in the newer accelerated washfastness tests.
The Research Model Launder-Ometers are thus
all-purpose units since they can be used both fcr
the standard tests and for special research work.
As standard equipment both the L-1-Q and
L-2-Q Model Launder-Ometers are supplied with a
vari-speed drive unit providing a selection of rotor
or jar rotation speeds of 15 to 50 R.P.M. All
Research Model Launder-Ometers are equipped
with Preheating Loading Tables which increase
the accuracy of the test by insuring that all speci-
mens are started at the same temperature. Prep-
aration of one set of specimens while another set
is being run also increases the volume of samples
that can be tested per working hour.
All electrical control equipment including the
thermo-regulator, direct reading dial thermom-
eter, switches, pilot light, relays, etc. are contained
in the control cabinet which is conveniently lo-
cated above and at the back of the Preheating Loading Table.
At the option of the purchaser the thermo-regulator and direct
reading dial thermometer
or Centigrade scales.
Inlets for hot and cold
rapidly draining the
tank or reservoir are
provided. A safety
switch disconnects the
drive motor whenever
the cover of the main
bath or reservoir is
raised. The water bath
and preheating table
are of stainless steel
and are insulated with
one-half inch corru-
gated asbestos protect-
ed by an outside metal

MODEL L-1-Q
The Model L-1-Q Research Launder-Ometer has
a maximum rotor capacity of 20 one-pint glass
jars, 20 one-quart glass jars or any combination
of one-pint and one-quart glass jars whose total
is 20. Five jars in a row are mounted vertically
at right angles to the rotor and shaft on each of
the four sides of the rotor and revolve radially
with the rotor and shaft. The rotor is so designed
that the one-pint glass jars are accommodated di-
rectly in the openings of the rotor castings. Easily
inserted and removed adapter discs are utilized
in the openings on the rotor castings when the
one-quart glass jars are being used. Adapter Plates
similar to those used in the Standard Launder-
Ometer are employed when the metal specimen
containers are used.
MODEL L-2.Q
The Model L-2-Q Research Model Launder-
Ometer will accommodate one-pint and one-quart
glass jars in the same number and manner as the
Model L-1-Q. In addition to the one-pint and one-
quart glass jars it will also accommodate a total
of 6 two-quart glass jars. This is accomplished
by the use of the two adapter units, each of which
hold 3 two-quart glass jars on opposite sides of
the rotor replacing two rows or 10 of the one-pint
or one-quart glass jars. In these adapters the two-
quart glass jars are mounted horizontally away
from and at right angles to the shaft and jar hold-
ing rotor. This adapter unit will also in the same
manner accommodate six of the 31/2 inch diameter
by 8 inch long metal tubes required for the new
Accelerated Washfastness tests.
If it is desired to utilize the 31/2 inch diameter
by 8 inch long Metal Specimen Containers re-
quired for the Accelerated Washfastness Tests in
the Model L-1-Q or more than six in the Model
L-2-Q Research Launder-Ometers; adapter plates,
each of which accommodate five metal containers,
are available. These adapter plates for the Re-
search Model Launder-Ometer, each hold five con-
tainers in a row in a similar manner to the five-jar
adapter utilized in the Standard Launder-Ometer.
There are of course some dimensional differences
between the 5-jar adapters used in the Research
and Standard Launder-Ometers but the distance
from the jar to the center of the shaft is the same
so that the arc of rotation is the same. Thus with
4 adapter plates a total of 20 metal containers can
be utilized in either of the Research Model Laun-
der-Ometers.

Used in 48 Countries throughout the World, Atlas Ometers are
the only universally accepted yardsticks of accelerated testing.
The world wide use of Atlas equipment is Indic- throughout the world checking the -qualify of raw similar materials was tested' by exposing to sun=
lik
i
ative of its acceptance as standard by all scientific
and industrial nations for performance tests of
raw materials and finished merchandise.
The time to test a product is prior to market
introduction; the place is in your laboratory. Like
so many self-evident truths, the significance is
sometimes overlooked. Well intentioned research
frequently stops short of hurdling the consumer
performance test, either because direct measure-
ments have not been possible, or is accomplished
only after expensive research.
In the field of sunproofness, washability and
weathering, Atlas has changed all that. Three
world famous instruments have provided since
1919 the necessary standardized, reproducible con-
ditions for evaluating quality in terms of consumer
use, at moderate cost and maintenance.
Thousands of Atlas instruments are in daily use
materials, safeguarding production, making it
possible to make and keep guarantees, stopping
rejects, complaints and adjustments: truly insur-
ance worth any reasonable premium. The value
of the millions of hours Atlas Ometers have saved
thousands of users all over the world during the
past thirty years in providing rapid reliable an-
swers to quality problems, is incalculable.
Atlas Ometers are versatile enough to cover
every legitimate need of the industries they are
designed to serve, and do their job so well they
enjoy government and engineering society endorse-
ment. A quarter century of unremitting effort,
generously aided by government, industrial and
scientific associations, has made these instruments
the accepted method of measuring performance
prior to use.
Prior to 191.8 the colorfastness of fabrics and
t was a co-
e
light-and if results were twice a
incidence! How could it be otherwise? The in-
tensity of sunlight varies with latitude, season of
year, time of day and clarity of the atmosphere.
Obviously these variables prevented a common
basis of testing, interpretation and action; tests
could often not be run for days, or but intermit-
tently, and never duplicated.
World War I brought restricted shipments of
dyestuffs to America thus making a bad situation
worse. It was into this chaotic situation Atlas in-
troduced the Fade-Ometer. Then came in rapid
succession the Weather-Ometer and Launder-
Ometer.
You may refer all problems of sunfastness, laun-
derability and weathering to the appropriate Atlas
Ometers with complete confidence that prestige
will he enhanced, net profit improved.

Transformers are required when your alternating current line voltages are other than within the range of 208 to 250
volts. We quote below separately the required capacity for each separate Ometer, and also on larger transformers
to accommodate more than one Atlas Ometer, or other laboratory equipment. By combining the current capacities when
more than one Ometer (plus other electrically operated laboratory machines) is operated from the power line, the
most suitable transformer can be determined. As indicated on three phase operation it is sometimes more economical
to utilize 2 single phase transformers instead of one 3-phase transformer.

WEATHER-OMETER?
The Weather-Ometer is a laboratory apparatus
for ascertaining at a greatly accelerated speed the
trend of reactions which will occur on all types of
products in outdoor exposures.
It is a self-contained machine, employing the
three principal weathering agents, Synthetic Sun-
light, Moisture and Temperature Changes.
Automatic control, regulation and application
of these weathering agents make it possible to
establish standard test conditions which can be
duplicated and reproduced at any time or place.
The need for such equipment is evident since in
addition to the extensive time required to obtain
results from exposures to actual weather, the re-
sultant tests will vary greatly not only from location
to location but from day to day, month to month,
and year to year at the same location.
FADE-OMETER ?
The Fade-Ometer is a patented self-contained
electrically operated device for determining by ac-
celerated tests in the laboratory the action of sun-
light on all materials.
The need for such equipment is evident in every
industry having products which fade or otherwise
deteriorate from the action of the sun. Natural sun-
light, available only part of a 24 hour day at best,
and frequently not at all, is never constant due to
the difference in latitude, season of year, time of
day and local climatic conditions.
The Enclosed Violet Carbon Arc, source of radiant
energy, provides noon June sunlight 24 hours per
day. The Fade-Ometer provides constant, uniform
and reproducible conditions regardless of time or
place, thus speeding up research and production
and insuring quality of product.

LAUNDER-OMETER?
The Launder-Ometer is the standard laboratory
washing machine of the American Association of
Textile Chemists and Colorists and is used through-
out the world for quickly determining the color-
fastness of textiles to commercial laundering and
domestic washing.
From one to twenty samples may be tested simul-
taneously under controlled conditions of tempera-
ture and mechanical action.
Available with either one-pint glass jars for the
standard tests or with metal containers for the
accelerated washfastness tests.
All Launder-Ometers have full automatic control
with a choice of electricity, gas or steam for heating
the water bath. The Preheating and Loading Table
is an indispensible accessory for added efficiency
and reduction of operator time.

The Fade-Ometer
What It Is and What It Does
The Fade-Ometer is a patented self-contained
electrically operated device for determining by ac-
celerated tests in the laboratory the action of sun-
light on all materials.
The need for such equipment is evident in
every industry having products which fade or
otherwise deteriorate from the action of the sun.
Natural sunlight, available only part of a 24 hour
day at best, and frequently not at all, is never
constant due to differences in latitude, season of
year, time of day and local climatic conditions.
The Fade-Ometer provides constant, uniform and
reproducible conditions regardless of time or
place, thus speeding up research and production
and insuring quality of output.
INSURES BETTER PRODUCTS
The dependable advance knowledge of color-
fastness obtained from the Fade-Ometer has point-
ed the way to many noteworthy improvements in
a wide range of products.
While a particular pigment or dye may be of
good fast-to-light quality for some applications,
a variation in its use may give radically changed
results. A short test in the Fade-Ometer will quick-
ly give an indication of its adaptability to new
applications and if found satisfactory permit guar-
antees of the color fastness of a new product.
DIMINISHES REJECTIONS
The Fade-Ometer by providing reliable color
fastness information in a short period of time
serves not only as a research tool in the develop-
ment of new and untried processes and products
but also as a means of checking the uniformity
and quality of material from the production line.
In production control alone it will pay for it-
self many times over as the rapid detection of
poor fastness-to-light qualities in a particular run
will enable early correction of the condition and
will possibly prevent thousands of dollars worth
of sub-standard products from being marketed.
The costly process of rejection and return with
the corresponding loss of good will, prestige and
confidence can thus be largely eliminated.
SALES PROMOTION
Any testing program which-determines the qual-
ity of products before production is started and
again checks the finished product before shipment
is fundamentally sound.. The use of proper quality
control prevents spoilage, raises production stand-
ards, and lowers costs. Such honest effort is re-
warded with greater sales and increased prestige.
In the field it serves, each Atlas Ometer has
made great contributions to greater net profit.
Many of our customers have found their compet-
itive position so improved that public announce-
ments have been made, and whole advertising
programs built around their use of Atlas equip-
ment.
Excellent Light-Fastness
PRINCIPLE OF ACCELERATED FADING
If radiation approximating Noon June Sunlight
both quantitatively and qualitatively is played on
specimens under controlled conditions of tempera-
ture and humidity it is to be expected that color,
chemical and physical changes will develop similar
to those produced by exposures in actual sunlight.
In the Fade-Ometer the acceleration of results
is accomplished by providing- continuously- 24 -
hours a day a test condition in which the various
factors producing the changes in the specimen are
maitained at their maximum values encountered
in actual sunlight exposures.

ATLAS FADE-OMETER
Poor Light-Fastness
TEMPERATURE
Ambient temperature at the face of the speci-
mens is controlled automatically to within ?3? F.
by a dial type thermo-regulator within the range
of 95? to 150? F. A dial type thermometer unit
is supplied as standard equipment with each ma-
chine which provides an easy convenient method
of measuring ambient temperature in accordance
with standard methods specified by the A.A.T.C.C.,
A.S.T.M. and Federal Specifications.
The ventilating system uses filtered air and the
ambient temperature is kept within the predeter-
mined limits by means of an electrically operated
blower actuated by the thermo-regulator. Close
control of temperature is very important and its
effect on most materials cannot be ignored.
HUMIDITY
A cylindrical stainless steel reservoir filled with
water at a constant level forms the base of the
testing chamber. Moisture is added to the filtered
air from the blower by evaporation of water from
wicks which are stretched on stainlesss steel frames
and which are partially submerged in the water.
With this method relative humidities up to 50%
can be obtained depending upon atmospheric con-
ditions and the number and condition of the wicks
used.
For those having a convenient source of water
the Fade-Ometer is usually supplied with the Atlas
Float and Valve. If it is not practical to pipe a
source of water to the machine, a five gallon bottle
can be supplied. In either case the water is auto-
matically maintained at a constant level in the
reservoir.
COST OF OPERATION
The Fade-Ometer is economical to operate both'
from the standpoint of material used and operator
time. The are consumes one inexpensive 1/2"x12"
carbon electrode in each 24 hours of operation.
Since the machine will operate continuously for
24 hours a minimum amount of operator attention
is necessary, only a few minutes a day for insert-
ing new carbons, cleaning the globe and inspecting
and changing specimens. The machine can be set
for automatic shut down for any period up to 24
hours thus increasing the usable machine hours.
With the arc operating at its normal 15 to 17
amperes and 120 to 145 arc volts the Fade-Ometer
consumes approximately 2.5 kilowatts. The water
consumption is about 5 gallons per 24 hour
period.
The special Pyrex globe or filter unless acci-
dentally damaged has a useful life of 2000 hours.
The wicks depending upon the hardness of the
water used require periodic washing and occa-
sional replacement as does the air filter depending
upon the amount of dirt in the air. All other
parts and accessories have a life expectancy of
years and do not normally require replacement;
SAFETY
The Fade-Ometer is designed to comply with
the various Safety Standards for ordinary use
conditions and may be safely operated through
the night without attention. With ordinary care
it may be safely operated without danger of per-
sonal injury to the operator or other laboratory
personnel.
SHIPPED COMPLETE
The Fade-Ometer is shipped complete ready to
connect to outlets of electric power and water.
Included with it are all of the necessary supplies,
accessories and operating instructions. There are
no extras to buy before the machine can be put
in daily operation.
ELECTRICAL CHARACTERISTICS
The Fade-Ometer can be supplied for operation
on Direct Current or Alternating Currents of 25,
40, 50 and 60 Cycles. On Alternating Current the
Fade-Ometer can be operated directly from any
two wires, or one phase, of any power circuit
having a voltage of 208 to 250 volts regardless of
whether it is a single phase, 2-phase or 3-phase
system. For any other line voltage, such as 110-
115, 185-207, 380, 440, 550, transformers can be
furnished which will bring the available line
voltage to the 208-250 Volt operating range of
the Fade-Ometer. On Direct Current the Fade-
Ometer will operate satisfactorily only on voltages
between 220 and 250 as transformers cannot be
utilized.

Description of Instrument
GENERAL CONSTRUCTION
The Fade-Ometer is of all metal construction
built to give years of dependable service. It is
totally enclosed, the upper part of the machine
forming the test chamber the bottom of which
consists of the stainless steel water reservoir and
the lower portion or base of the machine contain-
ing the blower unit, air filter, reactance trans-
former and other equipment.
Six doors are provided around the circumfer-
ence of the machine for easy access to all speci-
mens and to the interior of the machine as well
as an extra door for use when servicing the are
mechanism. The top is provided with a hinged
balanced louvre for ventilation which opens and
closes as the blower is actuated. The base is
equipped with hinged doors for easy inspection,
changing of the air filter and service of the blower
motor.
Legs elevate the base of the Fade-Ometer ap-
proximately five inches from the floor providing
for easy cleaning.
The Fade-Ometer requires a floor space of 43"
by 33" and measures approximately 68" in height.
CONTROL CABINET
The speed, degree and character of fading,
chemical and physical changes are a function of
time, temperature, humidity and radiation. All of
these variables must be subject to control within
the limits set by nature if comparable results are
to be obtained. The success of the Atlas Fade-
Ometer is based upon the uniformity and unremit-
ting constance of these physical conditions, rather
than to the use of artificial circumstances which
permit no correlation with actual use.
The Control Cabinet located at convenient eye
level has been designed with these objectives in
mind. A Voltmeter and Ammeter with special
scales are provided as a check on both the arc
and line voltages and the current consumed by
the arc. A four-point switch makes it possible to
regulate minor variations of are intensity due to
small fluctuations of line voltage.
The Time Switch provides an automatic means
of shutting off the Fade-Ometer at any predeter-
mined time within 24 hours, a great convenience
to the operator.
The Running Time Meter located on the side
of the control cabinet removes the personal ele-
ment of maintaining an accurate detailed log of
the actual hours of exposure received by the speci-
mens. Recording the meter reading at the start of
the exposure of any specimen or group and like-
wise noting the reading when removed enables the
operator to accurately determine the exact number
of hours of exposure they have received. This is
especially useful where specimens are started at
different times and are exposed for varying num-
bers of hours. The Running Time Meter is of the
nonresetting type which makes it impossible for
anyone to change the actual record of the exposure
hours.

A Main-Line Switch, Inspection Light Switch,
Thermo-Regulator, Pilot Lights and Voltmeter

TEST CHAMBER
Standard specimen holders and tests masks, for
a variety of materials, are supplied as part of the
equipment. The specimens, mounted in their hold-
ers, are suspended in the test chamber on a circu-
lar rack which engages both the top and bottom
of the holders insuring the proper vertical align-
ment at all times. These are rotated around the
light source at a constant speed at a fixed distance
of ten inches which insures equal radiation for, all
specimens.
The Fade-Ometer is operated with a full set of
holders which are filled with any available ma-
terial if a complete set is not required. In this
manner maximum uniformity of test condition is
attained.

Specimen Holders
The number of specimens tested simultaneously
may be varied from 9 to 126 depending upon the
size chosen.
The Type CD-LSR and SL-LSR Specimen Hold-
ers illustrated below are the ones most commonly
used since they provide ample exposure area and
will conveniently accommodate flat specimens such
as textiles, paper, plastic films, protective and
decorative coatings on metal panels, etc.
The Type TC-LSR is used for thick materials
-such -as rugs or carpets and the WP-TC-LSR for
large figured patterns such as wallpaper, cre-
tonne, rugs and carpets.

EXPOSURE MASKS
When testing a color of unknown fastness on a
material that is not temperature sensitive it is often
convenient to have progressive steps or stages on
one specimen. This can be accomplished by the
use of the exposure mask which has conveniently
printed and perforated flaps which permit the
operator to uncover portions of the- specimen in-
successive steps or stages.
Exposure masks and convenient filing folders
are supplied for use in the SL-LSR, CD-LSR and
WP-TC-LSR Specimen Holders.

ATLAS FADE-OMETER
The Atlas Enclosed Violet Carbon Arc
The heart of the Fade-Ometer is the Atlas Violet
Carbon Arc. This is an enclosed type arc which
produces a complete spectrum from 279m? through
20,000m?.
This spectral distribution is accomplished by
the use of the proper carbon electrodes operated
under controlled current conditions in a filter
globe of special optical Pyrex.
The filter globe performs three major functions.
First, it filters out the shortest of the ultraviolet
rays so that the resulting spectrum is extremely
close to that found in summer sunlight. Secondly
it prevents any possible contamination of the test
specimens from products of combustion of the arc
and thirdly by enclosing the are the carbon life
is greatly extended, so that a full twenty-four
hour operation is possible with the consumption
of a single twelve inch carbon electrode. As the
Pyrex glass is slow to solarize the globe has a
useful life of 2,000 hours without any appreciable
change in its transmission qualities.
So well was the original engineering on the arc
done that only minor changes have been made

%OF TOTAL RADIATION TO LIMIT OF FLUORITE TRANSMISSION IN INFRA-RED.
Chemical action may often be brought about by
the absorption of the infra-red, visible and ultra-
violet wavelengths. The literature cites innumer-
able instances of light acting as a catalyst in pro-
moting a reaction not otherwise taking place in
the dark, in altering the rate of reaction already
taking place, or in bringing about a new reaction
which is entirely independent of the one which
proceeds normally in the dark.
While the Fade-Ometer was designed primarily
to utilize these principles in measuring the degree
of fading of dyestuffs and the deteriorating in-
fluence of light in the artificial aging of rubber,
etc., its use as a research tool such as in the
qualitative analysis of materials by fluorescence
should not he overlooked.

Applications and Correlation With Sunlight
APPLICATIONS
The universal appeal of colors, and the necessity
for accurately advertising the permanency of the
dyes employed, make the Fade-Ometer indispens-
able in research, production and sale promotion.
Among the world-wide industrial users who have
depended upon the Fade-Ometer
ter century, are:
Dyestuff Manufacturers
Dry Color Producers
Dyers and Finishers
Textile Mills
Clothing Manufacturers
Ink Makers
Printers and Lithographers
Billboard Advertisers
Wall Paper Mills
CORRELATION
Correlation of fading tests either in Fade-
Ometers or actual sunlight is now possible through
the new calibration method which permits the ex-
pression of all test results in terms of Standard
Fading Hours.
The Standard Fading hour and Calibration
Method was developed by the National Bureau of
Standards in cooperation with the A.A.T.C.C.,
A.S.T.M. and other technical societies as a simple,
reliable and convenient method of measuring and
expressing the fading produced in terms of a fixed
arbitrary unit of measurement.
In the Calibration Method special light sensitive
paper is exposed simultaneously under the same
conditions as the specimens either in the Fade-
Ometer or in actual sunlight. After exposure the
faded paper is then compared and graded with
an index of standards and the specimens are cred-
ited with having received the appropriate number
-Government- Bureaus-and Departments-- -- - -of-Standard Fading-Hours.-
Purchasing Departments
Rug, Carpet and Upholstery Mfrs.
Merchants (Wholesale and Retail)
Rubber Manufacturers
Soap and Cosmetic Manufacturers
Plastics (Materials and Processors)
Pharmaceutical Manufacturers
Consultants and Testing Laboratories
College Laboratories -
Advertising Departments
Petroleum Laboratories
Leather Manufacturers
Universal reporting of all test results in terms
of Standard Fading Hours which are constant and
unchanging instead of the variable terms of Sun-
light or Fade-Ometer Hours will thus enable close
correlation of tests both in the same machine from
time to time, between different machines and
actual sunlight exposures. The importance of this
will be better appreciated when consideration is
given to the fact that actual sunlight varies widely
both in intensity and spectral distribution due to
geographic location, time of day, season and at-
mospheric conditions and Fade-Ometer hours may
vary according to the model and local conditions
under which the particular machine is operated.
After the fading rate of a Fade-Ometer under
its own particular operating condition has been
determined by the calibration method the number
of actual exposure hours required to produce a
given number of Standard Fading Hours can be
calculated and the exposure time adjusted accord-
ingly and conversely any number of actual ex-
posure hours can be expressed as Standard Fading
Hours.
While data is not yet available this calibration
method also presents a long range means of estab-
lishing in terms of a standard unit of measure the
averages of actual sunlight intensities for specific
locations as well as averages for large geograph-
ical areas. It also can be utilized for determining
the amount of radiation that can be expected based
on the end use of a specific product which will be
of help in the preparation of industry and gov-
ernmental minimum performance standards.
Interpolation of data assembled over a period
of years in which the values for both sunlight and
the Fade-Ometer represent general averages indi-
cates the following:
DYED TEXTILES
1 Hour FDA-R Fade-Ometer equivalent to 1.7
Hours of Summer Sunlight between the hours of
9 A.M. to 3 P.M. at Washington, D. C.

Universal Acceptance of the Fade-Ometer
The extent to which industry, technical societies
and governmental agencies sanction and specify
the use of a testing device is the best measure of
its approval as a standard. The Atlas Fade-Ometer
has the unique distinction of being the only uni-
versally accepted equipment for determining color
fastness to light.
A few of the many hundreds of these specifica-
tions are enumerated below. Where published
standards are not available for a particular prod-
uct it is recommended that the unknown be com-
pared with a specimen of known performance, or
that available specifications for products of a
comparable end use be employed as a guide.
COMMERCIAL STANDARDS
Many industries have by voluntary agreement
through the U. S. Dept. of Commerce adopted
commercial standards specifying minimum re-
quirements of quality, labeling and terms utilized
in merchandising. A few of these in which the
minimum requirements for light fastness are based
on Fade-Ometer tests are enumerated below.
CS16-29 Wall Paper
CS52-35 Mohair Pile Fabrics
CS59-44 Textiles, Testing and Reporting.
INDUSTRIAL STANDARDS
In addition to those industries who have adopt-
ed commercial standards there are many, such as
those listed below, who have adopted standard
methods of testing but who because of their par-
ticular problems prefer to leave minimum require-
ments to mutual agreement between the purchaser
and seller.

sometimes overlooked. Well intentioned research
frequently stops short of hurdling the consumer
performance test, either because direct measure-
ment have not been possible, or is accomplished
only after expensive research.
In the field of sunproofness, washability and
weathering, Atlas has changed all- that. Three
world famous instruments have provided since
1919 the necessary standardized, reproducible con-
ditions for evaluating quality in terms of consumer
use, at moderate cost and maintenance.
Thousands of Atlas instruments are in daily use
Used in 46 Countries throughout the World, Atlas Ometers are
the only universally accepted yardsticks of accelerated testing.
throughout -the world,- checking `the quality ofraw-
materials, safeguarding production, making it
possible to make and keep guarantees, stopping
rejects, complaints and adjustments: truly insur-
ance worth any reasonable premium. The value
of the millions of hours Atlas Ometers have saved
thousands of users all over the world during the
past thirty years in providing rapid reliable an-
swers to quality problems, is incalculable.
Atlas Ometers are versatile enough to cover
every legitimate need of the industries they are
designed to serve, and do their job so well they
enjoy government and engineering society endorse-
ment. A- quarter century of unremitting effort,-
generously aided by government, industrial and
scientific associations, has made these instruments
the accepted method of measuring performance
prior to use.
Prior to 1918 the colorfastness of fabrics and
similar materials was tested by exposing -to sun-
light-and if results were twice alike it was a co-
incidence! How could it be otherwise? The in-
tensity of sunlight varies with latitude, season of
year, time of day and clarity of the atmosphere.
Obviously these variable prevented a common
basis of testing, interpretation and action; tests
could often not be run for days, or but intermit-
tently, and never duplicated.
World War I brought restricted shipments of
dyestuffs to America thus making a bad situation
worse. It was into this chaotic situation Atlas in-
troduced the Fade-Ometer. Then came in rapid
succession the Weather-Ometer and Launder-
Ometer.
You may refer all problems of sunfastness,
launderability and weathering to the appropriate
Atlas Ometers with complete confidence the pres-
tige will be enhanced, net profit improved.

TYPE FDA-R FADE-OMETER EXPORT DATA SHEET
ELECTRICAL REQU i RBrIENTS
ALTERNATING CURRENT: The Fade-Ometer, Type FDA-R, will operate on voltages between 208 and 250. However, the
voltage at the point of operation should be determined so that if a transformer is required it can be shipped
with the Fade-Ometer.
If the voltage is from 185 to 207, a Booster Transformer is required. For other voltages such as 110, 440 or
550 volts, line-transformers are required. See separate sheet on transformers. The Fade-Ometer operates on any
two wires, or one phase, of a supply circuit having the proper voltage of 208 to 250 volts, regardless of whether
it is a single phase, 2-phase, or 3-phase system. The Type FDA-R Fade-Ometer consumes about 25 amperes for a 10
minute starting period and 15 to 17 amperes running circuit, or an average of approximately 2.5 KW.
DIRECT CURRENT: The Direct Current Fade-Ometer, Type FDA-R, will operate satisfactorily on a voltage between
220 and 250. Transformers CANNOT be used. on Direct Current. The Fade-Ometer, Type FDA-R, consumes about 25
amperes for a 10 minute starting period, and 12 to 14 amperes, running current, or an average of approximately
2.6 KW.

Transformers are required when your alternating current line voltages are other than within the range of 208 to 250
volts. We quote below separately the required capacity for each separate Ometer, and also on larger transformers
to accommodate more than one Atlas Ometer, or other laboratory equipment. By combining the current capacities when
more than one Ometer (plus other electrically operated laboratory machines) is operated from the power line, the
most suitable transformer can be determined. As indicated on three phase operation it is sometimes more economical
to utilize 2 single phase transformers instead of one 3-phase transformer.

ACCELERATED WEATHERING
The ATLAS WEATHER-OMETER is a laboratory apparatus for
ascertaining at a greatly accelerated speed the trend of re-
actions which can be expected in average outdoor exposures
on materials.
The WEATHER-OMETER is a self-contained machine, embodying
three weathering agents; namely, Synthetic June Sunlight, Mild
or Vigorous Rain (water spray) and Temperature Changes.
All three of these agents, so destructive to many materials,
protective and decorative coatings, are corralled, controlled
and brought into play on prepared laboratory specimens, so timed
and applied that the resistance to outdoor exposure of the
specimen under study is proved in days instead of months or years
of actual outdoor exposure.
Used the World Over
The WEATHER-OMETER is truly an accelerated weathering machine
safe to operate 24 hours a day without manual attention. The
name "WEATHER-OMETER" is a registered trademark, and refers only
to an ATLAS ELECTRIC DEVICES CO. product. The WEATHER-OMETER was
pioneered and developed by Atlas and is manufactured in its
entirety in our own plant.

ACCELERATED WEATHERING
Briefly, the WEATHER-OMETER gives an index of. durability
to both Manufacturer and User of the following materials; paint,
varnish, lacquers, enamels, protective coatings, bitumens,
asphalt, roofing, rubber, plastics, dyestuffs, rope and cordage,
textiles, weather-proof wire and cable, liquids; in fact any raw
or fabricated material that may be subjected to out-of-doors use
in different localities and climates.
Accelerated Weathering has proven profitable 'in predetermin-
ing in advance of fabrication the worth of any product, intended
for out-of-doors service.
The WEATHER-OMETER is an indespensible piece of equipment
to those interested in learning the weather resistance of a
product by providing dependable information in 1/25 of the time
required for actual outdoor exposure.

The WEATHER-OMETER is available in two standard types; namely
the Twin-Arc and Single-Arc, both of which are fully explained in
this bulletin. To aid you in selecting the Type and Model best
fitted for your work we have listed them in order of demand, first,
the model most generally used, the Twin-Arc, and second, the Single-Arc.
Before proceeding further, it should be borne in mind that the
floor space of both types is the same and that the light source,
the Atlas Violet Carbon Are, is employed in all machines. After
you have acquainted yourself with the essential differences, you
will better appreciate the reason for the two types.

ATLAS WEATHER-OMETERS
THE PRINCIPLE OF ACCELERATED WEATHERING
The ATLAS Accelerated Weathering Machine operates on the
following principle: If a Light Source, whose total radiation
approximates Noon June Sunlight, is played on the surface of
a material, under controlled temperature conditions and is
followed by a water spray of known temperature, pressure and
volume, the material thus.exposed will take on surface and
color characteristics similar to those produced by outdoor
exposure, but in much less time.
With a WEATHER-OMETER as a medium, it is possible to chart
the breakdown on a specimen in your'own laboratory.
SOLAR vs ARC INTENSITY
Table No. 1 below shows the relationship of outdoor sun-
light for 12 months to the Atlas Violet Arcs in a Twin-Arc
Weather-One ter.
The values shown in this chart are Milligrams per square
cm. of oxalic acid decomposed in one hour by the action
of Ultra Violet in the light source.

ATLAS WEATHER-OMETERS
LIGHT SOURCE Continued
Electrically the Atlas Enclosed Violet Carbon Are is main-
tained by the use of reactance transformers which insure a
stable are at a low power factor which means economy in current
consumption.
The Are operates on a potential of 130 to 145 volts at
15-17'amperes on a.c. The Weather-Ometer as a unit is designed
for operation on a power line of 2nF to 250 Volts a.c. Reducing
the arc voltage to 130-145 is accomplished by reactance trans-
formers which are an integral part of each Weather-Ometer.
The Are consumes one inexpensive Q" x 12" carbon in each
24-hourrperiod. This makes for economy in carbon consumption
and operator's time, since the are will automatically sustain
itself for a complete day and night.
Since most of the destructive action in sunlight is produced
by wavelengths below 3600 angstrom units, it is to be expected
that the light source chosen for the Weather-Ometer would exceed
in this region of the spectrum when compared to June Sunlight.
Table No. 2 below shows the relationship in percent of total
radiation between June Sunlight at Washington, D.C. and the
Atlas Enclosed Violet Carbon Arc. All measurements were taken
at one meter from the are at right angles from the center of
the Arc.

ATLAS WEATHER-OMETERS
LIGHT SOURCE Continued
.In order to transmit wave-lengths otherwise retarded by
common glass Atlas Violet Carbon Arcs are enclosed within an
optical Pyrex Globe which transmits wave-lengths as short as
2750 actual Angstrom Units. This globe therefore filters out
all wave-lengths below 2750 actual Angstrom Units not found
in sunlight at sea level and therefore not desireable for the
purpose.
The globe has a dual purpose as it also forms an air tight
chamber permitting the Are to function in a rarefied ionized
atmosphere. This accounts for the 24 hour life of an electrode.
Another function of the globe is to keep by-products of combustion
from the.arc from reaching the specimens or annoying those in
close proximity. Thus exhaust flues, ducts or blowers are not
necessary when using an Atlas Enclosed Arc Weather-Ometer.
WEATHERING CYCLE
Accelerated Weathering is frequently referred to in speci-
fications and technical literature as the Light and Water Spray
Test. Periodic wetting, followed by drying with a light source
with a reasonable control of 'the ambient temperature at the
specimen constitutes a weathering cycle.
All Weather-Ometers of the enclosed type are pr-ovided with
a Cycle Meter whose function is to automatically govern the
duration of the light and water period. Thus light and water
spray periods of any duration or combination are possible by
simply changing to another Selector Cam.
TEMPERATURE
Temperature is one of the factors in out-door weathering; by
this token temperature is automatically controlled in all Weather-
Ometers of the enclosed type..

GENERAL CONSTRUCTION
Both models of the TWIN-ARC WEATHER-OMETER as illustrated
on the preceding page are contained in a welded structural
steel frame 36" x 36" x 63" high which is finished in a dark
green enamel. This frame is of a rugged design which will
insure long life, at least 20 years.
TESTING CHAMBER
Directly below the Arch which supports the Arc Lamps is
located the. enclosed testing chamber which is provided with
air temperature controls. It consists of a sheet steel ex-
terior finished in baked gray enamel, lined with stainless
steel and insulated with asbestos materials and is approx-
imately 36" x 36" x 36".
The roof or ceiling of the testing chamber is composed of
three panels. The center panel supports the two arc lamps and
is raised and lowered with the arc lamps, when trimming or
loading the arcs, by means of a cable with suitable pulleys
and lever. This center panel when in the low position remains
elevated about 3/4" to guarantee adequate ventilation. Both
the front and rear panels are hinted and provided with the
necessary fittings so that they may be kept closed or open de-
pending upon the temperature desired in the testing chamber.
The front of the testing chamber consists of two full
length doors 17" wide which give free access to the interior
of the testing chamber.
The floor of the testing chamber consists of the stainless
steel water pan or sump which is fully described elsewhere in
this bulletin.
BASE
On the floor of the base of the Weather-Ometer are located
the two reactors, the rheostat for compensating minor voltage
changes, the drum driving mechanism and the blower assembly.
This section between the floor of the base and the bottom of the
testing chamber is enclosed with a perforated metal screen,
giving ventilation and protection.
Legs elevate the base of the Weather-Ometer approximately
eight inches from the floor providing for easy cleaning.

CYCLE METER
It is due to the CYCLE METER
that the Twin-Arc Weather-Ometers
owe their great flexibility. By
the utilization of interchangeable
specially cut CAMS or Cycle Selec-
tors, any type of testing cycle can
be provided. These CAMS control
independently the duration and
interval of the Light and Water
Spray periods. By selection of the
proper CAM the operator can have
any combination of light only,
light with water spray, or water spray
only.
All Twin-Arc Weather-Ometers
are provided with a number of
standard CAMS providing test cycles
which have been found to be most
efficient in their particular field.
For example the 102-18 CAM shown
inserted in the Cycle Meter above
provides for 102 minutes of light only followed by 18 minutes of light
with water spray. This is the cycle used for most types of materials.
The 51-9 CAM illustrated on the following page is used for
materials, which require a shorter wetting and drying out period as
this CAM provides for 51 minutes of light only followed by 9 minutes
of light with water spray.
Still another Cycle Cam is employed for bituminous products

CYCLE METER
In addition to the standard CAMS, of which the three des-
cribed on the preceding page are but a few of those now being
used, also furnished are Blank CAMS which may either be cut
by the user or returned to us for preparation of any special
cycle which the user desires to try out on his particular
product.
The only restriction on cutting special CAMS is that no
period of light or water spray can be of less than 3 minutes
or greater than 24 hours in duration and that the total time
of light plus water spray should be in multiples which are
divisible into 24 hours or less, as the CAM makes one revolu-
tion in 24 hours.
In order to change from one CAM to another merely remove
the knurled knob holding the cam in place, remove the one
CAM and replace with another CAM of the selected cycle.

VOLTMETERS
A Voltmeter for each-Arc is
provided in the Control Panel.
Each indicates to the operator
either the voltage at the Are or
the voltage of the power line to
the Weather-Ometer. These Volt-
meters, one for each are.. are
equipped with special dials which
not only permit reading of the
are or line voltage but also have
indicated on their dial the proper
are volt operating range of 130-
145 and line voltage from 200-250.
VOLTMETER SWITCH
A double-throw toggle switch is located directly below the
two Voltmeters making it possible to switch from Line Voltage to
Are Volt reading with the same meter.
AMMETERS
Two Ammeters, one for each
Are, are located on the right
side of the control panel.
These indicate the actual amperes
being consumed by the Are and are
equipped with special dials that
not only show the amount of
current being consumed but also
indicate the proper range at
which the arcs should be opera-
ted, 15-17 amps on a.c. or 12-14
amps on d.c.

RUNNING TIME METER
The Running Time Meter removes
the personal element of maintain-
ing an accurate log of the actual
light hours received by any or all
the specimens under test. By
simply recording the time reading
at the start of any specimen or
group and likewise noting the meter
reading when the specimen is removed,
the difference in the two readings
results in hours and tenths. The
Time Meter is a telechron driven
counter of the non-resetting type
which makes it impossible for any-
one to willfully or otherwise change
the actual reading of this meter.
ON AND OFF SWITCH
This double pole toggle switch is used for manually starting
and stopping the Weather-Ometer as it is the master switch for
all circuits.
TIME SWITCH
The Time Switch in the lower
center of the Control Panel,
provides means for terminating
the test or shutting down the
Weather-Ometer at any predetermin-
ed time from 1 to 24 hours. This
switch if undisturbed will shut
off all electrical and water
circuits at the end of 24 'hours.

VOLTAGE ADJUSTMENT SWITCHES
Frequently the voltage at the
location varies during the Day and
Night period, but not of sufficient
degree to warrant the changing of
connections on the Reactor Trans-
former. In order to conveniently
increase or decrease resistance in
the Arc circuit, each are is
provided with a Voltage Adjustment
Switch. Position No. 1 has the
maximum resistance in the circuit
for high voltage and No. 4 the
minimum resistance when voltage
is low, usually at the peak hour.
PILOT LIGHTS
Two Pilot Lights in red indicate that the Weather-Ometer
circuit is energized even though the arc lamps and water spray
may have been turned off by the time switch.
THERMO REGULATOR
In order to raise or lower the
temperature within the test chamber
a Thermo Regulator with a visible
dial is provided. This regulator
governs the volume of air intro-
duced into the test chamber. Thus
a range of 110? to 1800 F. ambient
temperature 5? F. is possible.
The Thermo Regulator is adjusted
to correspond to Black Panel Tempera-
tures which is higher than Ambient.

WATER SPRAY
The two most important factors in an
accelerated weathering test are Synthetic
Sunlight and Water Spray, each so timed
to be most effective on the subject under
test.
Since the Cycle Time Meter which
governs the duration of the Light and
Spray periods is fully explained else-
where this discussion will concern only
the water spray system on an Atlas Twin-
Arc Weather-Ometer.
It should be borne in mind that the
specimen spray is only in action when the
Cycle Cam demands spraying at which time
the spray issues from a series of four
vertical nozzles, as illustrated on the
right, and delivers a volume of water on
each vertical row of specimens as they
rotate past the nozzles once every minute
or 1.5 inches per second.
The actual amount of water delivered
by the specimen spray unit varies with
the type of spray nozzle in use at the
time and the water pressure at the
nozzles. Table No. 3 below shows pints
of water per minute delivered during the
spray period by the various type nozzles
at different pressures.

HORIZONTAL SPECIMEN SPRAY
A suitable Spray Unit is supplied with each HVDL-X Weather-
Ometer for use when a spray cycle is desired on horizontally
mounted specimens. As this unit utilizes only two nozzles of
the type used in the vertical specimen spray, the volume of
water delivered is 50% of the amounts indicated in Table No. 3.
SPECIMEN TEMPERATURES
In making Accelerated Weathering
tests, the subject of temperature is
usually one of grave concern since there
are three possible temperatures, surface,
ambient and embeded film, to be consid-
ered.
Since the materials to be tested
may vary in shade from black to white
with different heat absorbing rates, it
has been tentatively agreed upon by the
industry to record temperatures with a
Black Panel Thermometer. This device as
illustrated, is a stainless steel panel
.032" thick with approx. 100 sq. cm. of
surface on which is mechanically fastened
a bimetalic dial type thermometer with
the entire surface covered with two coats
of black baking enamel.
Black Panel Temperatures are approx.
30? F. higher in the Weather-Ometer test-
ing range than ambient temperatures and
the Thermo Regulator controlling the
temperature within the test chamber is
calibrated to indicate the selected Black
Panel temperature and not ambient temp-
erature.
DRUM COOLING SPRAY
Should the temperature in the test chamber be excessive for
the material under test, a two-nozzled water spray is provided
which plays on the outside of the testing drum. This side spray
should not be confused with the Specimen Water Sprays which
simulate rain fall. The sole purpose of the Drum Cooling Spray
is to remove by conduction excess heat from the test chamber and
at the same time increase the relative humidity.

SUMP
The spent water from the sprays is collected in a stain-
less steel reservoir covering the entire area of the base,
36" x 36", and is located directly below the specimen drum.
A suitable screened drain is provided of 14" pipe.
WATER PIPES AND FITTINGS
All necessary pipes, fittings and electric valves are
an integral part of the Weather-Ometer. This water system
all of copper and brass insures delivery at the specimens
of water free of rust or contamination from the water system.
Aluminum piping and fittings are available for deionized
systems.
WATER PRESSURE
The effective water pressure required to operate the machine
is 25 pounds per square inch (25 P.S.I.). Furnished as an integral
part of the water system is a Pressure Regulator 25 to 80 Lbs.
and a Pressure Gauge preceded by a 200 mesh Strainer of monel
metal.
REVOLVING DRUM SPIDER
Both the Vertical Testing Drum and Horizontal Testing Rack
when in use are mounted on and supported by the Revolving Drum
Spider. This spider is constructed of brass and is rotated
constantly at 1 r.p.m. through a friction drive by the motor
operated driving mechanism. This provides a uniform exposure
for all samples both to the light source and water spray.
VENTILATION SYSTEM
The Twin-Arc Weather-Ometer is equipped with a motor driven
squirrel cage type blower actuated by the Thermo Regulator. This
blower delivers 500 C.F.M. of air providing a two-fold action of
lowering the ambient temperature of the testing chamber and
introducing air for oxidation. The air is directed through ducts
and baffles to selected points within the testing chamber thus
assuring maximum efficiency.

VERTICAL SPECIMEN DRUM
In order to support test specimens in a vertical plane
when rotating them around the light source an aluminum drum
31" I.D. x 162" in depth is employed. The thickness of the
specimen holders furnished are of such dimensions that they
will bring the exposure surface or face of the test specimen
within a .circular plane of 30" in diameter as called for in
all testing procedures.
The entire inner periphery of this open ended cylinder
is fitted with equi-spaced vertical rails which will accom-
modate 30 double specimen holders, as illustrated on the fol-
lowing page, or 60 test panels 2-3/4" in width and 6-3/4" in
length. Smaller samples correspondingly increase the
capacity of the machine.
The sample holding arrangement of the drum is so designed
that practically any type and kind of material that !ends
itself to be suspended in a vertical position may be conven-
iently be placed in a Weather-Ometer. See Page No. 6 for il-
lustration of Vertical Specimen Drum in place.
HORIZONTAL TESTING RACK
When it becomes desireable to conduct an accelerated weather-
ing test on materials and objects which do not permit vertical
suspension, a circular testing rack is used in place of the
Vertical Testing Drum.
This Rack or Fixture as illustrated on Page No. 6 rests on
the same rotating spider which supports the Drum. It is provided
with 15 upright studs acting as an axis for the 15 Turn Tables
5" in diameter. Upon these Turn Tables may be placed Petri
dishes or odd shaped objects.
The 15 Turn Tables progress around the Arcs at 1 r.p.m.
twice during each revolution each turn table makes mechanical
contact with a leaf spring causing the turn table to make a 1/6
revolution on its own axis. In this manner each turn table
rotates once in every three revolutions of the Testing Rack.
When using the Horizontal Testing Rack the Right-hand Arc
is lowered to bring both Arcs to an equal distance from the
object.
The Weather-Ometer is designed to take both Vertical and
Horizontal specimens in the Model HVDL-X.

SPECIMEN HOLDERS
Specimens of any conceivable type
and kind of material may be placed in
a Weather-Ometer for testing. A wide
variety of standard specimen holders
for protective coatings on metal or
wood, rubber, plastics, textiles, cable
or rope are available, a few of which
are described and illustrated on this
page.
The specimen sizes most generally
used are 2-3/4" x 5-7/8", 3" x 6",
10" x 28" wire cable and rope from
1/8" to 34 O.D., Rubber under tension
2-7/8" x 6-3/4", Semi-solids (recep-

100 sq. cm., molded shapes 1/4 to 16
Cu. Inches.
A turn table is used when testing
semi-solids or molded shapes. See
Page 6.
The capacity of the standard
Testing Drum is 30 double holders or
60 specimens 2-3/4" x 5-7/8".
All vertical specimen holders are of the open back type to
permit a free flow of air on the back of the specimen. Non-
corrosive material such as aluminum, monel, stainless steel and
brass is used in the fabrication of the holders. Special Holders
to support objects not mentioned can be made to order.

SPECIAL TESTING DRUMS
THE TYPE BCS FOR WIRE AND CABLE
Weather-Ometer tests of insul-
ated wire and cable require a
special drum instead of the standard
drum with grooved slots. The Type
BCS Drum illustrated is interchang-
eable with the standard drum. It
provides simultaneous testing on as
many as 24 pieces of wire or cable
in lengths of 30" in sizes from
No. 4 to No. 0000.
The clamps are so arranged that
the wires are suspended at an angle
of approximately 33 degrees from
the horizontal thus permitting the
maximum number of specimens of
sufficient length for proper testing
to be exposed at one time. If wires
smaller than No. 4 are to be tested
smaller clamps can be furnished.
For the testing of wire and cable in sizes larger than No.
0000 a special drum is required. These can be furnished together
with the necessary enlargements of the Weather-Ometer testing
chamber which will permit testing of wire and cable in sizes up
to 3" in diameter. Complete details upon request.
SPECIAL DRUMS FOR OTHER MATERIALS .
Special Specimen Drums can also be.furnished for materials
where the weight or size of the specimens do not lend themselves
for use in the standard drum. For example when testing slabs
of concrete because of the added weight a special reinforced
drum may be necessary, Drums can also be furnished for the test-
ing of large specimens which could not be inserted in the standard
drum.
Complete details will be furnished upon receipt of fnformation
giving size, weight and nature of material to be tested.
Accelerated Weathering thus is not limited to a definite re-
stricted field but can be adapted to any type of product. The
Weather-Ometer thus is a very flexible tool which-has proved its
worth many times over in thousands of laboratories over the entire
world.

ENCLOSED MODEL SL-TS
Model SL-TS
Single-Arc Weather-Ometer
For those to whom rapidity
of test results is not the
prime consideration the Single-
Arc Weather-Ometer will prove
to be a reliable piece of
equipment for accelerated weath-
ering tests as it was for the
15 years prior to introduction
of the Twin-Arc Line of Weather-
Ometers in 1941.
The Enclosed Single-Arc
Model SL-TS Weather-Ometer is
a very flexible instrument and
is identical in all respects
to the Twin-Arc Weather-Ometer
as described in this bulletin
with the exception that
instead of Two Violet Carbon
Arcs, one Are only is employed.
SINGLE ARC vs SUNLIGHT
Table No. 1, Page 3, compares
Ultra Violet Radiation of the
Twin-Arc and Sunlight. Using
the same method of determination,
the Single-Arc decomposes 4.95
milligrams of oxalic acid per
Sq. cm. in one hour as compared
to 9.44 for the Twin-Arc.
In view of the amount of
ultra violet received at the
test specimens it is to be ex-
pected that the Single-Arc
Weather-Ometer will take twice
the time necessary to produce
the same results in the Twin-Arc.
The Enclosed Model SL-TS Single-,Arc Weather-Ometer like the
Twin-Arc incorporates the latest developments in accelerated weath-
ering equipment. The Cycle Meter, by simple change of the Cam or
Dial, will automatically provide any combination of light and spray
periods desired. Together with temperature control, improved water
spray and drum revolution of 1 R.P.M. the Model SL-TS provides test
conditions heretofore not possible with Single-Arc Weather-Ometers.

OPEN MODEL BWM-CC
The Open Model Single-Arc
BWM-CC Weather-Ometer with the
exception of minor refinements
and improvements is the origi-
nal Weather-Ometer which was
pioneered and developed by
Atlas over 20 years ago.
It is a thoroughly depend-
able instrument and was the
machine called for in all speci-
fications written before
introduction of our Twin-Arc
Weather-Ometers in 1941.
Although rapidly being re-
placed by the Twin-Arc Weather-
Ometer the Open Model Single-
Arc BWM-CC is still a valuable
instrument for grading and
sorting where the factors of
speed and control of temperature
and humidity are relatively un-
important.
Its fixed cycle of 17 minutes
light and 3 minutes spray is
produced by the specimens trav-
eling through a shielded water
spray once in each 20 minute rev-
olution of the testing drum. Thus
the operator does not have the
wide selection of light and spray
periods now demanded and only enjoyed with the Twin-Arc Models..
The temperature of the test specimen in this model although
not automatically controlled never becomes abnormally high, since
the specimens enter the shielded water spray once every 20 minutes.
The Open Model Single-Arc like all Weather-Ometers employs
the Atlas Violet Carbon Are as previously described in this bulletin.
This model is of the same rugged and long life construction as all
other models and occupies the same floor space with the same general
electrical and water requirements.
Since. this model employs only one Are it is to be expected that
twice the time will be consumed in testing as compared with a Twin-
Arc Weather-Ometer.

ASPHALT TRIMMER
Films of asphalt or other bituminous materials of a uniform thickness
applied under controlled conditions of temperature are a requisite to de-
pendable test results in either Weather-Ometer (accelerated weathering) or
actual out-door tests.
The Atlas Asphalt Trimmer is a convenient and dependable instrument
with which the average operator can with ordinary care produce films of a
uniform thickness within a tolerance of + 0.001".
The doctor bar under which the coated panel is passed is an elec-
trically heated machined stainless steel tube which may be raised and
lowered vertically to control the thickness of the film. A variable
voltage transformer is employed to regulate the doctor bar temperature
which is measured by an indicating pyrometer. The table or plate on which
the panels are passed under the doctor bar is level and fixed and is
heated to prevent chilling of the coating material prior to and during the
trimming operation.
The Asphalt Trimmer comes complete with switches and pilot lights
for both the doctor bar and plate and a cord for connection to a lighting
circuit of 110-120 volts or a power circuit of 208-250 volts 50-60 Cy. A.C.

WEATHER-OME ?
The Weather-Ometer is a laboratory apparatus
for ascertaining at a greatly accelerated speed the
trend of reactions which will occur on all types of
products in outdoor exposures.
It is a self-contained machine, employing the
three principal weathering agents, Synthetic Sun-
light, Moisture and Temperature Changes.
Automatic control, regulation and application
of these weathering agents make it possible to
establish standard test conditions which can be
duplicated and reproduced at any time or place.
The need for such equipment is evident since in
addition to the extensive time required to obtain
results from exposures to actual weather, the re-
sultant tests will vary greatly not only from location
to location but from day to day, month to month,
and year to year at the same location.
Accelerotor?
Wet and Dry Abrasion Tests
FAD -OG I TC Q ?
The Fade-Ometer is a patented self-contained
electrically operated device for determining by ac-
celerated tests in the laboratory the action of sun-
light on all materials.
The need for such equipment is evident in every
industry having products which fade or otherwise
deteriorate from the action of the sun. Natural sun-
light, available only part of a 24 hour day at best,
and frequently not at all, is never constant due to
the difference in latitude, season of year, time of
day and local climatic conditions.
The Enclosed Violet Carbon Arc, source of radiant
energy, provides noon June sunlight 24 hours per
day. The Fade-Ometer provides constant, uniform
and reproducible conditions regardless of time or
place, thus speeding up research and production
and insuring quality of product.
Write for complete catalogs describing each machine.
LAMjibDD ER-OO AAETER?
The Launder-Ometer is the standard laboratory
washing machine of the American Association of
Textile Chemists and Colorists and is used through-
out the world for quickly determining the color-
fastness of textiles to commercial laundering and
domestic washing.
From one to twenty samples may be tested simul-
taneously under controlled conditions of tempera-
ture and mechanical action.
Available with either one-pint glass jars for the
standard tests or with metal containers for the
accelerated washfastness tests.
All Launder-Ometers have full automatic control
with a choice of electricity, gas or steam for heating
the water bath. The Preheating and Loading Table
is an indispensible accessory for added efficiency
and reduction of operator time.

LIFE OF ELECTRODES ..
A full load or trim of Electrodes should burn from 22 to 24 hours.
SECOND LOAD OR TRIM ..
Remove the upper electrode which is now 8 to 9 inches long and from
it out TWO 4-inch lengths (102 mm). Insert a new 12-inch electrode
of the opposite kind (Cored or Solid) in the upper carbon holder and
use the TWO 4.ineh pieces in the lower holder.
Cutting the 4-inch lengths for the lower carbon holder from the upper
electrode prevents waste of carbon.
CAUTION: BOTH LOWER ELECTRODES MUST ALWAYS BE OF THE SAME KIND
(CORED OR SOLID), NEVER MIXED, AND MUST BE OPPOSITE
FROM THE KIND USED IN THE UPPER HOLDER OR THE LAMP WILL
NOT*OPERATE PROPERLY OR HAVE PROPER FADING QUALITY.
HV The partly consumed electrodes may be cut into 4-inch (102 mm)
lengths by inserting them in the "Cutter" (see packing list) -
Electrode Receptacle and Cutter). Turn or rotate electrode
against the 'saw blade, scoring same. The carbon can then be
easily broken by hand at the scored point, 4-inches (102 mm).
4 - The lower carbon holder accommodates two 4-inch (102 mm)
carbons of a like kind but opposite to the kind used in the
upper holder.
5 - By using two carbons in the lower holder, it is possible to
burn the Arcs over-night or 24 hours with a minimum amount of
downward travel of the Arc (see cut).

an In trimming the Are Lamp, insert a 2 x 12 inch (305 mm)
electrode, either #70 solid or #20 cored, in the upper carbon
holder, passing it through the bushing of the gas chamber and
through both rings of the clutch which lifts the upper electrode.
Tighten up the thumb screw so the carbon wil 1 be held securely
in the upper carbon holder.
2 TWO carbons are employed in the lower holder for the purpose
of insuring full 24-'hour life and a minimum amount of downward
travel of the Are.
NOTE: The lower carbon holder of this Are Lamp is designed to
take TWO j x 4" carbons. These may be either TWO #20
Cored carbons or TWO #70 Solid carbons. Kindly bear in
mind that when #20 Cored carbons are used in the lower
holder, an opposite carbon, such as #70 Solid, must be
used in the upper holder. If TWO #70 Solid carbons are
used in the lower holder, #20 Cored carbons should be
used in the upper holder.
CAUTION:
DO NOT TIGHTEN TIE LOWER CARBONS TOO TIGHT. IF $00

TEMPERATURE CONTROL
A motor driven blower in the base of the Machine supplies the proper
amount of air for cooling and oxidation essential to an accelerated
test.
A temperature controller recorder controls the movement of the blower.
This recorder is fully described in back of these pages. The same
"key" used to wind the clock of this instrument is used to set the
temperature selector.
TOP VENTILATOR
Two trap doors make up part of the roof or top of the Machine
enclosure. The correct amount of ventilation, when the Machine is
in operation, will be governed by various factors, such as Room
Temperature, Room Air Currents or Drafts, Desired Temperature
required in test.
WATER PAN
A tank or sump below the specimen drum provides both a receptacle for the
spent water from the two spray units and a floor to the testing chamber.
Because of bacteria growth and mineral deposits, the tank or sump
should be cleaned out at frequent intervals.
A water spray contacting the outside of the testing drum produces a
cooling effect and at the same time increases the relative humidity
of the chamber.
CAUTION: It is not advisable to conduct a Weather"Ometer test with
the side or cooling spray inactive, unless temperatures
higher than 150?F or 65?C are desired.
SPECIMEN SPRAY
In the rear of the testing drum is located the mild spray unit,
This unit is designed to accommodate several types of nozzles or
tips. The tips or nozzles differ only in shape and volume of water
released.
The nature of the material to be tested will determine the tip
or nozzle best suited for the work.
NOTE: The duration of the spray period is determined by the
Cycle Cam. The force of the spray is determined by manual
adjustment governed by good judgment.

- #9200-PX GLOBE -
Place the small asbestos pad in the bottom of the
globe. Place globe in position with its upper edge properly
seated against the upper side of the gas check plate, and
swing the wire bail in position against the bottom of the
globe. The tension of this wire bail should permit the
globe to be rotated by grasping the globe between both hands.
This seating is important, if air enters globe at upper edge,
the life of the electrodes will be shorter by 6 to 10 hours.
Globes must be free from chips or cracks and kept clean.
2 This globe is of a special pyrex for transmission
of the same wavelengths found in sunlight. Globes must be
free of chips or cracks and kept clean for reliable results.
After each 24 hours of use, globes should be washed with
granulated or other soap, dried and polished thoroughly.
By keeping on hand an extra globe which has been cleaned and
polished, no testing time will be lost. Globes should be
discarded after approx. 1500 hours use as they will have be-
come so etched and solarized (pink in color) that they will
not permit the proper transmission of active light.
- LENGTH OF ARC -
3 The Fade-Ometer is, now ready to operate and the
switch may be closed. The are should start immediately and
within a few seconds settle. down to a steady intensity. The
are, to have proper fading qualities, is longer than an
ordinary illuminating arc or motion picture arc. Do not be
alarmed at the length of the arc. It will be from 12 to 2
inches long.
- WHEN FIRST TURNING ON -
4 A slightly colored gas will form"inside the glass
globe. In less than a minute this gas will clear out. If.
a brown deposit forms in the globe, look for chip in edge of
globe or for cracked bushing. Excess air has entered the
globe. Correct before continuing with test.

VOLTMETER ANL AMMETER
Each are is provided with a voltmeter and ammeter for the
purpose of indicating electrical status of the arc. Since approxi-
mately 15 minutes are required for the arc to settle down to a
steady flame, disregard the meter readings until the are is
stabilized.
VOLTMETER SWITCH
(Gang toggle below voltmeter)
This double throw switch permits reading Line or Are Volts
VOLTAGE ADJUSTMENT
The Weather-Ometer has an operating range from 208 to 250
Volts. Each machine is set for the voltage specified by the
purchaser. Occasionally the voltage given when ordering does not
correspond with the actual line voltage at the Weather-Ometer.
See instructions on the wiring diagram at the back of this folder,
and make the necessary changes in the connections of the reactance
coil. Once the proper connections are'made in the reactance coil,
no further changes are necessary unless the line voltage is
permanently changed.
4 At the bottom of the control panel are two voltage adjusting
switches, one for each are. These are identified as to the are
they control and are for adjusting minor voltage changes. They
out in or out a limited amount of resistance, increasing or
decreasing the are voltage and amperage as desired.

2 Amperes should be hovering (not fixed) between 15 to 17,
rather 17 amps., arc voltage between 120 to 145 volts. If amperes
are less than 15, turn switch "2", "3", or "4" position to bring
the amperage and volts to the desired range, favoring 17 amps.
rather than 15.
3 NOTE: Occasional dips in line or are voltage should not
be confused with a constant low voltage condition.
4 Line voltages are usually lower during the day and higher
at night. The operator will soon acquire the knack of setting
and adjusting switches for day and night operation according to
the prevailing conditions.
5 NOTE: Ampere and are voltage readings on the meters will
never remain fixed for any length of time. Disregard slight
fluctuations; they are due to the other electrical loads on the
same line.

INSTALLATION INSTRUCTIONS
THESE INSTRUCTIONS REFER TO THE INSTALLATION OF
THE NEW LAVA TYPE GAS CHAMBER AND FEED FLOOR USED
ON ALL ATLAS ENCLOSED ARC LAMPS.
FIRST - SEE PRINT NO. FO-1028
REMOVING OLD GAS CHAMBER
The burnt out or defective gas chamber can easily be
removed by shearing off the heads of the three screws with
a sharp cold chisel. These screw heads are found on the
under side of the gas chamber. After these have been sheared
off, strike the burnt out casting a few sharp blows and it
will drop off. Next remove the upper casting or feed floor.
NEW LAVA TYPE GAS CHAMBER AND FEED FLOOR
This consists of four pieces. First, the lower casting,
#03-086, which is similar to the old gas chamber. Second, the
lava bushing, #03-088. Third, the feed floor which is also a
casting. Fourth, the lava washer.
These two castings with lava bushing are assembled in
the same manner as the old type, with the exception that, after
the three screws are tightened up, the lava washer is laid on
top of the feed floor. You will note that two of the screws
are about one-fourth of an inch longer. They should pass
through the lava washer, one in front and one to the right,
facing the carbon holder. The shorter screw should be placed
in back. This screw does not pass all the way through the
lava washer. If it did, there would be danger of short-
circuiting on the carbon clutch that comes in close proximity.
When all the screws and nuts are tightened up, one
should be able to turn the lava bushing, #03-088, slightly.
If it is fitted too tight, it will crack, due to the heat
generated by the are.
When these parts are assembled, you will note there is
a small recess between the top of the lava washer and the lava
bushing. This is designed on purpose, so as to allow the lower
part of the clutch (#03-039) to drop down on top of the bushing
when the are feeds.
Should you have occasion to order additional set of gas
chamber and feed floor, kindly mention No. 03-086X.

when the pen lifter has more than one arm.
To Remove Pen-Arm: Hold the pen-arm bracket
(Item 11, Fig. 5823) to prevent side motion and
springing out of calibration. With fingernail, knife
blade or small screw driver raise the upper end of the
pen-arm over the stud, at the same time sliding the
pen-arm downward.
To Replace Pen-Arm: Hold the pen-arm bracket
with fingers to prevent springing out of calibra-
tion. Place the pen-arm in position so that the
rivet in the pen-arm will slide into the slot in the
bracket, and the open end of the pen-arm will
slide over the taper stud. With the pen-arm in this
position, simply push it into place.
V-Pens
Caution: Do not change angle of pens from that
shown in Fig 3207. Pens for a two pen instru-
ment are shown. In a single pen instrument, the
pen makes a right angle with the chart.
Fig. 3207
To Ink a "V" Pen: Use the dropper, and put a
drop or two of ink in the pen. At normal tempera-
tures and with ordinary records, this amount will
last for days. See if the ink is feeding by drawing a
piece of smooth paper across point of the pen. If
the ink does not flow freely, a moistened piece of
paper held against the pen point will start it.
"V" Pen Adjustment: Careless handling in trans-
portation may alter the correct adjustment of the
pen. Slip the pen in or out of the holder (it is only
friction-tight) until it touches the chart. Do not
bend the pen-arm to obtain adjustment. If, after
long use, the pen makes a heavy line, it is.wasting
ink. Put in a new pen.

Chart Holder (Fig. 4015)
The chart holder assembly is fastened directly
to the case, but it is unnecessary to remove it when
removing the chart disc or changing the chart. It.
consists of a rigid arm chart hub holder (5) and
semi-circular wire chart holder (4). The loop end
of the wire chart holder is caught in a slot (8) in
the chart disc which keeps the wire chart holder in
position and holds the chart flat against the disc.
The chart hub (9) is held in the crook at the end of
the chart hub holder (5), always in position to be
snapped back on the chart hub base after replace-
ment of the chart.
To Change Chart
Lift Pen: Place finger tip under the lever arm on
the pen lifter (3) and raise the pen lifter.
Remove Chart: Place the tips of the first and
second fingers behind the knurled rim of the chart
hub. Press the button in center with thumb. The
chart hub will release instantly. Remove the chart.
(If the instrument contains a mechanical clock,
be sure the spring is wound sufficiently to run
proper period of time. Do not wind too tightly).
Replace Chart: Slip the chart under the wire
chart holder, pen index, pen lifter, and time set
pointer (1). Place hole in the chart over the collar
on the chart hub base and insert the hub in the
base. Grasp the hub by the knurled rim and push
straight in. It will automatically snap into position.
Do not press guide finger on the time set pointer
toward the chart disc as this will cause the chart
to stick and prevent its turning easily.

Adjust for Time: Turn the chart hub to the left
until the proper time arc is indicated by the time
set pointer. (Note day and night sections on chart.)
Ink pen as described on the following page and
close door. The pen will be automatically adjusted
to the chart when the door is latched.
Time Set Pointer (Fig. 4015)
The time set pointer (1) is properly adjusted
when the instrument leaves the Factory and sel-
dom needs adjustment. It is designed for ease in
accurately adjusting the charts to the desired time
arc, so that it is not necessary to have the pen on or
near the chart to adjust the chart for time. The
guide finger (2) on the time set pointer is for the
purpose of guiding the chart under the time set
pointer. The time set pointer and the pen point
must indicate the same time arc.
To Adjust Time Set Pointer: Place the chart on
the instrument. This adjustment should be made
when the pen is near the outer edge of the chart be-
cause the chart can be located more accurately when
the pen is in that position. Be sure the chart disc
(see below) is in position. Slightly loosen the two
screws that hold the pointer to the chart disc. Turn
the chart until the pen point rests exactly on the
time are. Adjust the time set pointer to indicate the
same time arc. On instruments subject to overrange
the time set- pointer should be set so that the pen
point will pass the pointer. Tighten the two screws.
Chart Discs
The. wedge-fastened chart disc (Fig. 4015) is
readily recognized by the odd-shaped hole around
the chart hub and the two finger holes above and
below the hub.
The self-locking chart disc (Fig. 5823) is readily
recognized by the small egg-shaped hole around
the chart hub and the finger holes (17) on the
right-hand side.
Wedge-Fastened Disc (Fig. 4015) : The chart
disc rests on several lugs on the side of the case
and is held in place by sliding wedge fasteners (6)
and a notch under the pen lifter (3). It is also held
rigidly below the chart hub (9) by a clip (7) which
pivots on the lower clock screw. To remove the
disc, first twist the lower end of the wire chart
holder (4) in a counter-clockwise direction until
the end loop can be pulled through the slot (8) in
the disc. Turn the clip (7) slightly to the right to
release the chart disc. Slide out each wedge fastener
(6) with the thumb or the forefinger, grasp the free
end between the thumb and the finger and push into
the slotted post. Remove the chart disc with a slight
outward pull to lift it over the wedge fasteners and
a slight downward motion to free it from the
base of the pen lifter and the chart holder mounting.
To replace the disc, reverse the above operation.
Sell-Locking Disc (Fig. 5823) : The Foxboro
self-locking chart disc rests on four lugs at (12).
It is correctly positioned by stops at (13) and (15),
and held in place by projections (14) and (15) and
the clip (7).
To Remove Disc: First raise the pen lifter and the
chart hub. Release the lower end of the wire chart
holder by turning counter-clockwise until the end
loop can be pulled though the slot in the disc.
Catch this end around the chart hub. Push the thumb
piece (16) clockwise, which releases clip (7). Grasp
the disc through the two holes (17), remove with a
motion to the left and then a slight outward move-
ment to the right.
To Replace Disc: First place V-notch in the left
side of disc firmly against the V-shaped stop (18)
with the upper edge of the notch resting on lug (12)
adjacent to stop (18). Move the disc in until it
rests on the other three lugs and to the right against
the right hand stop, (13) (it automatically centers
itself against the other stops). Swing clip L counter-
clockwise until it locks over the disc in the notch.

CLOCKS
Mechanical Clock
Fig. 5985
When it is necessary to have the' clock serviced,
remove it from the instrument.
Removing the Clock
Remove the pen arm, chart and chart disc. Re-
move the screw in the chart hub base, then unscrew
the chart hub base. Remove the three screws extend-
ing through the top of clock box and lift clock out.
Replacing the Clock
Remove the nuts from the screws which extend
through the bottom of the clock box. The three
holes in the clock match those in the case in one
position only. Find correct position and fasten the
clock in place with screws furnished. Replace the
chart hub base and screw. Replace the chart disc
and chart. Check setting of the time set pointer and
adjust if necessary.
Boxing and Shipping the Clock
Retain in a clock box, stuffing with soft paper.
Then pack in a larger box with cushion of excel-
sior, or other soft packing material, on all sides.
Address plainly to The Foxboro Company, Fox-
boro, Mass., U. S. A.
Cleaning and Oiling the Clock
Clocks with various periods of winding are
furnished. Be sure the spring is wound sufficiently Mechanical clocks should be cleaned and oiled
to run the proper period of time, but not wound too once a year. If service is severe they should be
tightly. Extension handle keys are supplied for oiled more frequently. Send to The Foxboro Com-
easy winding. pang

MAINTENANCE
Once installed, the Instrument should require no
further attention or maintenance except to see that
the cover or door is tightly closed at all times to
keep out dust or corrosive fumes.
Rotax Brush and Commutator Assembly
If because of abnormal conditions or careless
handling the brush and commutator assembly be-
comes damaged, it is advisable to return it to Fox-
boro for repair. The surfaces are carefully bur-
nished and the spring tension definitely adjusted
before the instrument is calibrated. Any increase
in brush tension may affect the calibration, re-
sponse or current-carrying capacity of the contacts.
If the contact area becomes dirty, resulting in
poor contact, they may be readily cleaned with
benzine or ether. Do not use carbon-tetrachloride
or Carbona as it leaves a film of chloride on silver
surfaces which may reduce the conductivity. Use a
piece of clean bond paper with two edges that are
clean cut and free from lint, such Ps would be
obtained by tearing off the lower right hand cor-
ner of this sheet.
Disconnect or shut-off the power supply before
cleaning.
Dip the paper in the cleaning solution and pass
it between the brush and the segment - do not
press on the brush with a pencil or other instru-
ment - the normal spring tension of the brush
should be sufficient. Do not lift the brush from the
segment - simply pass the paper between them.
BENZINE AND ETHER ARE HIGHLY IN-
FLAMABLE - BE SURE ALL CURRENT SUP-
PLY IS SHUT-OFF. BE SURE ALL CLEANER
HAS EVAPORATED BEFORE CLOSING THE
CASE OR AN EXPLOSIVE MIXTURE MAY
ACCUMULATE WHICH WILL BE IGNITED IF
THE RELAY OR CONTROLLED CONTACTS
SPARK.
Contact Spacing Adjustment
The point at which a segment and brush make
contact, closing the electrical circuit, may be
changed by means of the control point setting key
or knob, or by turning the micrometer adjusting
screws on the individual discs. Turning the screw
clock-wise will move the point of contact down
scale; counter-clockwise, up scale. Since the con-
trol point indicates the position of the contact, it
may be necessary to readjust as mentioned below.
The adjustment screws turn easily; do not bear
too heavily or the assembly may be thrown out of
alignment. Use a small screw-driver, such as used
to tighten eye-glasses, held between the thumb and
index finger of the right hand. Hold the assembly
from moving with the thumb and index finger of
the left hand at the pivot point.
POINTER ON
MICROMETER
Fig. 6315
Control Point Index - Adjustment
The control point index-arm may be set to show
the position of any one of the several contacts, and
is adjusted by means of the micrometer screw just
above the pivot point. Turning the screw clockwise
moves the pointer down scale; counter-clockwise,
moves the pointer up scale.
Contact Identification
Contacts are numbered consecutively from the
top or front to the back, the last disc being the
common. Contacts which close on increasing meas-
urement are designated as plus, and contacts clos-
ing on decreasing are designated as minus. An
assembly designated as "1+2+3-4" is an assem-
bly consisting of four commutators, the first two
of which close the circuit on increasing measure-
ment, the third on decreasing measurement, and
the fourth the common disc. Each brush lead is
tagged with a numbered metal marker to show the
brush and disc to which it is connected.

 The modest looking globe on your Fade-Ometer or Weather-Ometer is a very important part of this
equipment. By excluding air, the carbons burn much longer, thereby making possible long life and
economical operation. Furthermore, the special glass from which the globe is made is partly respon-
sible for making the are spectrum a close duplicate of the sun. These very important points are of
course predicated upon a CLEAN glass globe - and glass will get dirty in use. You cannot expect full
light intensity, with consequent maximum efficiency and uniformity of results, with a dirty globe. A
letter from the National Bureau of Standards is reproduced below to stress the great importance of
daily cleaning and polishing.

Q,TW
"Ten years ago (September 1929) * we were impressed with the need
for washing the globes, based on the following simple experiment.
Two new globes were taken from the same box. One of these globes
was measured for transmission while new. The other globe was put
into service for three months (globe cleaned every day). At the end of
three months, the transmission of the used globe was measured (1)
while badly smoked, (2) lightly wiped, and (3) washed thoroughly.
"The observed transmission in percent, calculated to a constant
thickness of glass (1.45 mm) were as follows:

"These values are only approximate calculations for a difference in
thickness from about 2.4 mm to 1.4 mm and may be in error by a
few percent, since they apply to a spectral range rather than to a
simple wave length. However, you will note that by washing the globe
(even after three months of service) it tends to approach a new, un-
used globe."

GENERAL INFORMATION
SECTION 1
THE CYCLE OF OPERATION OF A TWO STAGE COMPRESSOR
It is generally considered inadvisable to employ ordinary refrigerating
compressors of the Single Stage type directly on evaporators involving
temperatures below Minus 40? C, using Freon 22 as the refrigerant.
At minus 40?C, the refrigerant pressure in the evaporator is
approximately 0 pounds pressure per square inch. Assuming a 165 pound
to 190 pound gauge head pressure, would mean a compression ratio of
15 to 1. By splitting the compression into two steps, compression can
7gd held to 5 or 6 to 1 in each step, and thus obtain high efficiency
in compression and over-all performance.
The suction gas from the evaporator is fed to the main suction of the
compressor, and is compressed by three (3) pistons, thus raising the
pressure of the gas from the low vacuum of 17 to 22 inches to approximat ely
5 pounds per square inch.
After being conpressed in the three cylinders of the first stage, it
passes through the respective discharge valves and is then fed into
the suction side of the one cylinder of the second stage, where it is
recoup ressed from 5 pounds to 165 to 190 pounds. his action is
possible because the suction gas from the main evaporator at 20 inches
vacuum is so rarified that three cylinders even at 5 pounds discharge
will not supply sufficient volume to feed the one second stage cylinder.
Obviously for Minus 60?C operation, this same engineering was Advisable.

GENERAL INFORMATION
SECTION 1 (continued)
THE INTER-STAGE OR SECOND STAGE
The interstage is made up of as an auxiliary evaporator operated in
multiple with the main evaporator, and with a separate expansion Valve "H"
but with its suction feeding into the interstage instead of the main suction.
This evaporator is only for the purpose of cooling the second stage
cylinder.
After the suction gas from the main suction has passed through the first
stage, and is compressed, it becomes ielatively hot the to the heat of
compression and if it were fed directly at this high temperature into the
single cylinder of the second stage, it would have a tendency to burn up
the valves, and decrease the over-all efficiently.
The expansion valve of the second stage should be nearly closedo When
the machine is started up, it will be found that the interstage pressure
will be about 30 pounds gauge. But when the low temperature is reached
the pressure will vary from one (1) pound to Twelve (12) pounds. It is
desirable to have a cool suction line into the second stage but not a
frosted line. The frost should taper off about six (6) inches from the
location of the expansion valve Bulb. In the event that the valve should
have to be changed, the new bulb "W" can be strapped in the suction line
at this location instead of inserting the bulb in the line. Cut the old
bulb line off approximately two (2) inches from the suction line and
solder it closed.

SECTION 2
LIQUID LEVEL TEST COCK "X"
The Receiver "DD" is equipped with a Liquid Level Test Cock "X", which is
a small Purge Valve, with a 3/16" square key. To the Test Cock "X" is
attached a small tube ending about 1/3 way up in the Receiver "DD". If
the liquid refrigerant stands up to the end of this tube, it can be drawn
off through the Test Cock "X". This is the normal reserve to be main-
tained in the receiver "DD" . It should be checked with the machine in
operation, at about the lowest suction pressure at which the system
normally operates.
The liquid level will vary slightly with the suction pressure, being
LOWEST at the lowest evaporator temperatures. In testing, "crack", or
.open slightly, the Test Cock "X", and if gas VAPOR emerges add
refrigerant until test shows that the gas is in LIQUID state.
SECTION 3
COMPRESSOR OIL PUMP "Zt' Figure 1
The amount of oil pressure will depend on the suction pressure in the
crank case and on the temperature of the oil. The oil will have a
HIGHER PRESSURE at higher crank case pressure; and LOWER PRESSURE at
low crank case pressure. For example, at a crank case pressure which is
read on the compound gauge on the front panel of 0 pounds the gauge on the
oil pump may read 50 to 60 pounds. At a suction pressure of 20 inches, the
oil pump gauge should read at least 15 pounds (15 lb, pressure above 0#
plus 10 lb. below 0#)s so that the actual oil pressure should read
approximately 25 pounds. A positive oil pressure is necessary to raintain
adequate lubrication of the bearings, and also proper lubrication and

SHAFT SEAL "Y"
The seal bellows is secured to the shaft with a Seal Nut "Y-1" with a
soft copper gasket "Y-3" between the rear plate of the bellows "Y-2" and
"Y-5"
the shaft "Y-4" shoulder. There is a hole/drilled in the shaft under the
seal bellows that furnishes oil from the oil pump to the inside of the
seal. The oil then passes through the grooves of the main bearing "Y-6"
in the front gearing back to the crank case housing.
Seals can be lapped smooth in the field on a plate of glass using pumice
stone and oil on the brass face. The steel face of the Bearing Plate can
be lapped with the fine steel lapping compound and then finished with
pumice stone.
CAUTION Be sure parts are cleaned after lapping. DO NOT USE COMPOUND ON
BRASS FACE. Use only pumice stone and oil on brass. Make sure the
Oil Ports in the shaft are clean.
TESTING DISCHARGE VALVES OF COMPRESSOR.
To test discha rge valves, run machine down on a vacuum and close the
main suction Valve "U". A rapid rise in pressure in the crank case
indicates that one or more of the first stage of discharge is leaking
pressure back from the second state. A slow rise is normal due to the
second stage high pressure leaking back by the piston.

GENERAL INF OR MAT I ON
SECTION 6
COMPRESSOR OIL 11HH1T
At the time of shipment, the unit is filled with the proper amount of
oil, which is approximately 10 pints. It is of special characteristics,
and for that reason an extra supply of 5 Gallons is furnished in the
supplies shipped with the machine. It has a viscosity of 320 rated at
37?C. Check the amount of oil in the unit when the machine is off. The
correct amount is one half way up on the sight glass in the crank case.
THIS OIL WILL ABSORB MOISTURE FROM THE AIR, consequently it is imperative
that you keep in air tight container at all times. Further, it is
naturally expected that the oil used should be Free Flowing at the low
terrpmrature for which this Freezing Cabinet Specifications call for,
namely, Minus 601C. The oil we furnished is of that type.
SECTION 7
MOISTURE IN THE SYSTEM
Moisture in the system will cause the Valves to stick, and give an
erratic action. Moisture will also cause the oil to de-wax and
separate. Whenever it is necessary to change a Valve or have the
system open for any length of time, Change the Dryer "FF".
SECTION 8
DRYER - ""FF11" DAVISON N K
The Dryer "FF" is filled with Silica Gel "I]M", and has the action of
sbsorbing moisture as gas passes through it. The Dryer has screens at
both ends, but one end has several small screens to stop fine particles
of dirt or silica from passing into the system. BE SURE THAT DRYER IS
PLACED WITH OUTLET IN THE RIGHT DIRECTION. Dryers are refillable, but
care should be taken in keeping the unused portion of Silica-Gel from

the dryer.
In an emergency, one end of the Dryer can be capped and other hooked to a
vacuum pump, and in this manner place the Dryer in an over of not over
97?C, and leave to heat for at least four (4) hours. This is not good
practise, however, as the Dryer will contain some oil that will burn and
char, and this method will only net approximately 40% efficiency.
SECTION 9
REMOVING AIR
The presence of air in the system indicates moisture has been drawn in
and is especially harmful. To remove air, turn machine off and "crack"
(meaning opening slightly) the Discharge Service Valve "T", until the
Head Pressure has dropped to normal. This nay have to be done several
times. The Discharge Service Valve "T" on the head of the compressor is
of the Back-Seating Type. When the stem is all the way in, the line from
the condenser to the compressor is closed. When the stem is backed all
the way out, the valve is open to the condenser and closes the 1/8" Port"BB"
in the valve. With the Valve Back-seated, the 1/8" Iron Pipe Plug can
be removed. Now open the valve a little, and oil and air or gas will come
out.
When purging air out of the system, oil and gas will also escape, but not
enough oil will be lost to affect the machine, but enough gas may be lost
to warrant replacing it. Check the Test Cock "X" meat oned in Section 2 for

not condense. The air will usually stay up in the condenser. When the
system has air in it, the Head Pressure will be too high. (Refer to
Figure 9 for values).
SECTION 10
HIGH HEAD PRESSURE
High Head Pressure does not always indicate air in the system. If the
condenser is dirty, and the air restricted around the machine, the Head
Pressure will rise above normal. When starting the machine up, the
Head Pressure should drop to normal as per chart 9. The Head Pressure
chart does not always hold true, and the machine might be 10 pounds over
the temperature pressure chart due to conditions that are not visible
to the eye.
SECTION 11

protection to prevent damage to the Motor "CC". The motor should be
lubricated with the grease provided with the use of an Alemite Gun "JJ"
after it has been in operation for approximately six months, as the motor
is filled with grease when shipped from the factory. To lubricate the
motor, the operator will notice that there are two 1/8" Iron Pip Plugs on

damage the inside of the motor. Also too much grease in' the bearing housing
will cause overheating of the motor, and subsequent damage.
SECTION 12
DEFROSTING THE CABINET
Defrosting the cabinet is done in two ways. One is to scrape the surplus
frost from the cabinet walls with a wide putty knife. SCRAPE ---- DO NOT
PICK, OR HAMMER OFF, THE FROSTING. The other way that is more satisfactory
but not as fast is to turn the machine off with the Toggle Switch "N" on
the front panel, but leave the Main Power supply on. Door can be opened
to hasten the defrosting. The machine will run in short cycles, and pump
down, but no refrigeration will take effect.
SECTION 13
COMPRESSOR FAILURE
In the event the unit is electrically energized, and no refrigeration is
taking effect, a serious condition may result. We suggest calling in your
maintainence man. Some times the back pressure due to some difficulty will
rise about 25 pounds. In that case the compressor will stall and throw the
reset button of the Motor Starter "R". To remedy this, the Main Suction
Service Valve "U" should be closed tight, and the reset pushed in so that
the crank case will free itself of gas. After several starts, the crank
case will drop down to a vacuum and pump will run free again.

COMPRESSOR FAILURE
While doing this be sure the toggle switch "N" on the Front of Control Panel
is in an "Off" position. After the crank case is free, open the suction
line very slowly, until the low side coil has been cleared of high pressure
gas as shown on Compound Gauge "A". Now the Toggle Switch "N" may be turned
on again.
The reason the machine stalls is that the compressor is desigend to handle
the rarified gas and if suction pressure is too high, it crowds the second
Stage of Compression.
SECTION 14
QIL FILLER PLUG
Do not tighten Oil Filler Plug "V" too tight. Use some form of sealing
compound, such as Glycerin Litharge on the threads as a sealer.
SECTION 15
LEAK TEST FOR FREON 22
The leak test for Freon 22 is done with any good testing torch, such as
the Halide, for instance. The manufacturer of such torch will provide
information as to means to test for leaks. Generally oil around a fitting
or bolt is a very good indication, BUT DO NOT RELY ON OIL AROUND THE BOLT

only half a turn at a time on the adjustment. It sometimes takes from 20
to 30 minutes for one adjustment. Refer to Figures 2, 4, and 5.
SECTION 17
PUMPING DOWN THE SYSTEM
When the system is not to be used for several days, the Main Power Supply
should be left on, and turn the Toggle Switch "N" off on the front control
panel. The machine will pump down and shut off of its own accord.
If the main power supply is turned off, the gas will expand when the
cabinet warms up, and do some damage to the compressor or expansion valves.
SECTION 18
SHUTTING DOWN THE MACHINE
To shut down the system, either for moving from one location to another,
or if desired not to use for some period of time, the method is to follow
the PUMPING DOWN procedure outlined in Section 17. After the cabinet has
defrosted and all the gas has been pumped into the Receiver, Turn Toggle
Switch "N" on momentarily, whi4hopera the solenoid "B" enough to show 0 to
5 pounds on the Suction Gauge "A". Now close all valves and disconnect
the power.

SECTION 19
SERVICE VALVES
All service valves are of the Bonnet Type. This means that there is a
"bonnet" or protective cover, which must be renvved in order to close or
open the valve, and replace. There are four (4) Service Valves:-
1. MAIN SUCTION SERVICE VALVE "U", is located on the side of the compress-
or and the large suction line is flanged to it. This valve is of the Back
Seating Type, and the 1/8" Iron Pipe Plug Port "BB" is closed if the valve
stem is backed all the way out. This port is for charging gas to the
system, and to install an extra gauge to check the system. Also the gas
can be by-passed from the Head into the Low side through this port to
raise the pressure for leak testing.
2. DISCHARGE SERVICE VALVE "T" is located on the side of the head of the
compressor and connects to the condenser tube. This valve is of the Back
Seating Type, and has an 1/8" Iron Pipe Port "BB" that can be removed,
and connections made here to purge air off, or discharge the gas from
the system into a tank, or by-pass to the Low Side.
3. ONE-WAY SHUT OFF VALVE "C" is at the inlet of the Receiver and connects
to the outlet of condenser. Must be open whenever the machine is running.
4. ONE-WAY SHUT OFF VALVE "D" At the outlet of the Receiver connects the
liquid line here and supplies the expansion valves with the liquid. This
valve has a dip tube on the bottom that picks the gas off the bottom of
the receiver. Theyystem will not work unless the liquid gas is
delivered to the expansion valves.
NOTE: VALVES "C" AND "D" appear alike, the difference being that
Valve "C" has no dip tube, whereas "D" has a dip tube.
All Service Valves have a cap over stem to insure against leaks.

LIQUID LINE SIGHT GLASS "EE"
The Liquid Line Sight Glass "EE" is located in the Liquid side of the system
beyond the Dryer "FF" and Screen "K" and Solenoid Valve "B". This glass will
be solid with liquid and show no bubbles if system has plenty of gas, and the
..Dryer or Screen are not restricted and Solenoid is wide open. If the Dryer,
Screen, or Solenoid Valve should restrict the line, the glass will show bubbles
or foaming, or that the system is short of Freon 22.
SECTION 21
GAUGES "A" AND "E"
The system is equipped vid. th Two (2) Indicating Gauges:
1. A High Pressure Gauge "E" has a range from 0# to 300# and is connected with
a small copper tube to the discharge service Valve "T" of Figure 1. This
gauge will indicate the pressure on the condenser, receiver and Liquid line,
and up to the orifice of the Expansion Valves "F", "G" and "H".
2. A Low Pressure Gauge "A" has a range from 30" to 100 pounds of vacuum and
is connected with a small copper tube to the Main Suction Service Valve "U".
This gauge will give the pressure reading from the Expansion Valve orifice
through the low side coil and the crank case of the compressor.

to prevent dirt from getting into the valves.
3. Screen "J" is a large screen in the suction line located at the Main
Suction Service Valve "U". This screen is flanged and can be opened for
cleaning.
All screens can be cleaned with Naptha and should be dried thoroughly before
installing back into the system.
SECTION 23
EXTRA SUPPLY OF DRUMS AND REFRIGERATING GAS FREON "22"
An additional supply of Freon "22" is provided, sufficient for a Single Re-
charge of the entire system. These drums are of the approved test type, and
when supply of refrigerant Freon "22" has been removed, care should be taken
to refill with the same type Refrigerant, Freon "22". The use of any other
refrigerant will not permit the best results to be obtained, and will result
in trouble in attenipting to secure lowest temperatures, as are desired.
The drums should be stored in a cool room temperature not over 50?C. Fittings

Removable Pen Arms
To prevent damage to pen arms, it is advisable
to remove them when work on the instrument ne-
cessitates the removal of the chart disc, especially
when the pen lifter has more than one arm.
To Remove Pen-Arm: Hold the pen-arm bracket
(Item 11, Fig. 5823) to prevent side motion and
springing out of calibration. With fingernail, knife
blade or small screw driver raise the upper end of the
pen-arm over the stud, at the same time sliding the
pen-arm downward.
To Replace Pen-Arm: Hold the pen-arm bracket
with fingers to prevent springing out of calibra-
tion. Place the pen-arm in position so that the
rivet in the pen-arm will slide into the slot in the
bracket, and the open end of the pen-arm will
slide over the taper stud. With the pen-arm in this
position, simply push it into place.
V-Pens
Caution: Do not change angle of pens from that
shown in Fig 3207. Pens for a two pen instru-
ment are shown. In a single pen instrument, the
pen makes a right angle with the chart.
Fig. 3207
To Ink a "V" Pen: Use the dropper, and put a
drop or two of ink in the pen. At normal tempera-
tures and with ordinary records, this amount will
last for days. See if the ink is feeding by drawing a
piece of smooth paper across point of the pen. If
the ink does not flow freely, a moistened piece of
paper held against the pen point will start it.
"V" Pen Adjustment: Careless handling in trans-
portation may alter the correct adjustment of the
pen. Slip the pen in or out of the holder (it is only
friction-tight) until it touches the chart. Do not
bend the pen-arm to obtain adjustment. If, after
long use, the pen makes a heavy line, it is wasting
ink. Put in a new pen.

Chart Holder (Fig. 4015)
The chart holder assembly is fastened directly
to the case, but it is unnecessary to remove it when
removing the chart disc or changing the chart. It.
consists of a rigid arm chart hub holder (5) and
semi-circular wire chart holder (4). The loop end
of the wire chart holder is caught in a slot (8) in
the chart disc which keeps the wire chart holder in
position and holds the chart flat against the disc.
The chart hub (9) is held in the crook at the end of
the chart hub holder (5), always in position to be
snapped back on the chart hub base after replace-
ment of the chart.
To Change Chart
Lift Pen: Place finger tip under the lever aria on
the pen lifter (3) and raise the pen lifter.
Remove Chart: Place the tips of the first and
second fingers behind the knurled rim of the chart
hub. Press the button in center with thumb. The
chart hub will release instantly. Remove the chart.
(If the instrument contains a mechanical clock,
be sure the spring is wound sufficiently to run
proper period of time. Do not wind too tightly).
Replace Chart: Slip the chart under the wire
chart holder, pen index, pen lifter, and time set
pointer (1). Place hole in the chart over the-collar
on the chart hub base and insert the hub in the
base. Grasp the hub by the knurled rim and push
straight in. It will automatically snap into position.
Do not press guide finger on the time set pointer
toward the chart disc as this will cause the chart
to stick and prevent its turning easily.

close door. The pen will be automatically adjusted
to the chart when the door is latched.
Time Set Pointer (Fig. 4015)
The time set pointer (1) is properly adjusted
when the instrument leaves the Factory and sel-
dom needs adjustment. It is designed for ease in
accurately adjusting the charts to the desired time
are, so that it is not necessary to have the pen on or
near the chart to adjust the chart for time. The
guide finger (2) on the time set pointer is for the
purpose of guiding the chart under the time set
pointer. The time set pointer and the pen point
must indicate the same time arc.
To Adjust Time Set Pointer: Place the chart on
the instrument. This adjustment should be made
when the pen is near the outer edge of the chart be-
cause the chart can be located more accurately when
the pen is in that position. Be sure the chart disc
(see below) is in position. Slightly loosen the two
screws that hold the pointer to the chart disc. Turn
the chart until the pen point rests exactly on the
time arc. Adjust the time set pointer to indicate the
same time arc. On instruments subject to overrange
the time set- pointer should be set so that the pen
point will pass the pointer. Tighten the two screws.
Chart Discs
The wedge-fastened chart disc (Fig. 4015) is
readily recognized by the odd-shaped hole around
the chart hub and the two finger holes above and
below the hub.
The self-locking chart disc (Fig. 5823) is readily
recognized by the mall egg-shaped hole around
the chart hub and the finger holes (17) on the
right-hand side.
Wedge-Fastened Disc (Fig. 4015) : The chart
disc rests on several lugs on the side of the case
and is held in place by sliding wedge fasteners (6)
and a notch under the pen lifter (3). It is also held
rigidly below the chart hub (9) by a clip (7) which
pivots on the lower clock screw. To remove the
disc, first twist the lower end of the wire chart
holder (4) in a counter-clockwise direction until
the end loop can be pulled through the slot (8) in
the disc. Turn the clip (7) slightly to the right to
release the chart disc. Slide out each wedge fastener
(6) with the thumb or the forefinger, grasp the free
end between the thumb and the finger and push into
the slotted post. Remove the chart disc with a slight
outward pull to lift it over the wedge fasteners and
a slight downward motion to free it from the
base, of the pen lifter and the chart holder mounting.
To replace the disc, reverse the above operation.
Self-Locking Disc (Fig. 5823) : The Foxboro
self-locking chart disc rests on four lugs at (12).
It is correctly positioned by stops at (13) and (15),
and held in place by projections (14) and (15) and
the clip (7).
To Remove Disc: First raise the pen lifter and the
chart hub. Release the lower end of the wire chart
holder by turning counter-clockwise until the end
loop can be pulled though the slot in the disc.
Catch this end around the chart hub. Push the thumb
piece (16) clockwise, which releases clip (7). Grasp
the disc through the two holes (17), remove with a
motion to the left and then a slight outward move-
ment to the right.
To Replace Disc: First place V-notch in the left
side of disc firmly against the V-shaped stop (18)
with the upper edge of the notch resting on lug (12)
adjacent to stop (18). Move the disc in until it
rests on the other three lugs and to the right against
the right hand stop, (13) (it automatically centers
itself against the other stops). Swing clip L counter-
clockwise until it locks over the disc in the notch.

SECTION 31
STARTING THE UNIT
A. Before attempting to start the unit, we suggest that a thorough
review be made indicated in our General Information with frequent
reference being made to the sketches attached hereto as a guide to
the various parts which are employed in starting the unit, in
maintaining the desired temperatures, and the subsequent operation
of the Freezing Cabinet under the most desirable circumstances.
First of all, check over the wiring and Power Supply.
Next, and an item which is extremely IMPORTANT, make certain
that the motor when energized is running in the proper direction. Your
unit should have the motor running in the direction so that the
compressor pulley is operating in a clockwise direction, looking
in the bottom section of the box from the rear.
B. You are now ready to adjust the Valves.
1. Open Valve "U" all the way, then close it two turns. Open
Valve "D" until pressure rises on low side gauge to approxi-
mately 35 or 40 pounds. Leak lest System with Halide Torch.
This leak test need not be made particularly with the Halide
torch indicated, but a good make should be used as a precaution.

 Approved For Release 2001/11/21 : CIA-RDP80-00926AO07800250001-0
Be 2. Open Valves "T" and "C". If there were no leaks, Valve "D" may be
opened again and system and power supply turned on. If there is a
leak, leave Valve "D" closed and pump the pressure down to
approximately 2 or 3 pounds, before making repairs.
Co CHECK THE CONTROLLING DEVICES
1. The High Pressure Cut-Out "L" is a Safety Device only and will stop
the motor in an emergency.
2. Power for the Thermostatic Control "S" is taken from one side of the
line, 220 Volts, and reduced through a Transformer "0" to 110 Volts.
A second transformer "P" reduces the current to 24 Volts.
3. Thermostat "S" makes contact when satisfied. When satisfied, the
relay "PP" falls into position, closing the Solenoid Valve "B", cut-
ting in the Lows Pressure Switch "L" in the motor starter circuit.
When Thermostat is calling, the motor starter makes contact and the
Solenoid is energized. The Low Pressure Switch is By-Passed.
4. There is an "On and Off" Toggle Switch "N" on the panel which will
close the Solenoid "B" and cut in the Low Pressure Switch "L" by
by-passing the Thermostat. The solenoid line passes through a Back-
Acting Switch "M" connected to the Low Side. This Back-Acting Switch
serves to allow the coil to cool down gradually by throttling the
liquid supply. When the coil reaches a temperature corresponding to
that of tbn (10) inches suction pressure, the expansion Valves "F",
"G" and "H" then function normally.
D CHECK THE OIL LEVEL, through Sight Glass "GG" (See Figure 1) in
base of compressor. This oil level should be about the center of
the glass when compressor is off. This sight glass should be
checked a second time, an hour or so later, after the box has
cooled down.

E. GREASE THE MOTOR, with proper grease.
F. CHECK THE BELT TENSION. Belts should not be taut.
G. SET THE LOW SIDE CONTROL "L" to cut in at five (5) pounds, and out
at sixteen (16) inches of Vacuum.
H. MAKE SURE TO REPLACE THE CAPS (or bonnets) on all Service Valves.
J. UNLESS THE UNIT IS SHUT DOWN PERMANENTLY, the Power Switch should
always be closed.
For short periods of shut down, the Toggle Switch "N" should be used.
With this Switch "N" on the "Off " Position, it will still permit the
Compressor unit to idle and maintain an equilibrium between the High
and Low Side of the Compressor.
When lower temperature is desired, put Toggle Switch "N" on the
TOn" Position.
K. It will not be possible to determine whether the unit is short of
Refrigerant until after it has been in operation, for a period of time,
approximately four to five hours.

d. Expansion Valve may be defective, and will so indicate when
2. Unit runs on high suction pressure and the compressor is
cold due to the expansion valve overfeeding liquid, due to
the valve held open because of dirt particles or a damaged
valve seat.
Clean or Replace Valve.
B. INSUFFICENT REFRIGERATION
1. Pressure Control not properly set. Check the temperature setting. After
the unit has pulled down to the desired temperature, the control setting
should be checked.
2. Refrigeration load is too great. Usually caused by adding excessive
quantities of warm product. Check with the operator.
3. Air cooled condensers plugged with dirt. Keep condenser clean. Use a
long bristle brush or vacuum cleaner.
4. Air in the system. Purge. Leak test. Then check charge.
C.RECOIVMENDED SERVICE OPERATIONS
1. LEAK TESTING.
Use a Halide torch, or equal, as per directions on the particular make of
torch, Do not hurry this operation. Small le & s take several seconds to
show flame color, after applying tube toI,the suspected joint. The presence
of oil around a joint usually indidates a leak.

C. Recommended Service Operations Procedure
2. DISCHARGING REFRIGERANT FROM SYSTEM
a. Connect a drum to the Discharge Gauge fitting of the compressor. The
drum must be empty and evacuated, or have sufficient space to receive
the charge. The connecting line must be at least ten (10) feet long,
and must have agauge T'd into the line.
b. Close the compressor discharge service Valve all the way into the right.
c. Pump put the system into the drum by running the unit intermittently
so that the drum does not overheat. If necessary, run an little water
or place wet rags on the drum so that the temperatures are kept low
enough to avoid melting the fusible plug on the drum. Cool drum by
placing in tub of cold water at about 500 C.
d. When a gauge on the compressor suction service valve registers a full
vacuum, the system is pumpted out.
e. Remove drum and pump a vacuum on the system with a discharge service
valve gauge fitting open to remove last traces of Freon 22 Refrigerant
from the system.
3. CHARGING REFRIGERANT
A. Connect a drum of clean, dry, 'oil-free refrigerant to the compressor
Suction Gauge connection by means of a charging line, or 1/4" 0 D
tubing. Be sure there is no air in the system. Before tightening the
flare nut on the charging line (refer to Section 19) on the valve
connection of the compressor, open the drum valve slightly which will
blow the air out of the line. Run the unit with the canpressor suction

possible, weigh the charge in, standing the drum on a scale. The
drum should be upright to admit gas, never Liquid, to the unit.
b. Before completing the charging, back the service valve out to admit
refrigerant to the low side to obtain normal operation before
checking the charge. This unit has a TEST COCK. which indicates
,the correct charge. Open the Valve, and be sure a spray of cold,
clear liquid comes out. If gas or oil are discharged, continue
adding refrigerant. The charge for this machine is thirty (30)
pounds of Freon 22 Refrigerant. The drum can be placed in a bucket
of warm water to hasten gas flow.
4. PURGING AIR FROM SYSTEM.
Install a 1/4" Purge line from the Discharge Service Valve Gauge
connection into a waste bucket. Run the unit a few minutes until
condenser is warm. Stop the unit and immediately open the discharge
service valve to allow the air and gas to blow out freely. The
valve must be left open-until head pressure becomes normal. This
may require several blows of about ten (10) seconds each, also some
liquid or oil may blow out. After purging, check to see if the unit
has enough charge*
5. CHANGING OR CLEANING EXPANSION VALVES.
Close the Liquid Receiver Service Valve "D" and pump the system down
if possible. If the cabinet is warm, open the Liquid Receiver Valve
slightly above one (1) pound. Never open the system when the suction
gauge shows a VACUUM. If necessary, attach a drum of refrigerant
with a gauge in the line to the suction service valve, and admit
enough gas to bring the pressure above one (1) pound. Never allow

the system to remain open; immediately plug all open liras. This
is to keep the system dry. Never remove a valve uniil all frost
and moisture has been warmed off.
b. After tightening connections, admit enough refrigerant pressure into
the lines and remove plug or gauge from compressor Discharge
Service Valve to purge air out.
c. When installing a new valve, be sure the capillary tube does not
touch any suction lines, or very erratic operation will occur.
Install the bulb in a similar manner to the one removed, as any
change in location is apt to throw the system out of balance.
d. To clean expansion valve, remove it as above indicated, and blow it
out with Freon 22 from a drum. If the screen is plugged, remove
and clean in naphtha or high test gasoline; dry, and then replace.
If moisture was causing the stoppage, the Silica Gel Dryer should
be removed and replaced.
6. CHAN.ING COMPRESSOR OR VALVE PLATE
a. Pump down as instvnctions indicate in Section 17. When pressure is
balanced, close compressor Service Valves. Remove cap screws from
valves.
b. After repairs are made, run unit to secure a vacuum on crankcase
and see that it holds when compressor is stopped (Refer to Sect. 5).
Co Admit slight amount of Refrigerant by Cracking liquid receiver
valve and opening suction service Valve "T" until gas blows freely
from compressor discharge plug opening.
d. Open Liquid valve and start unit. If the valve -plate or seal requires

THE FREON REFRIGERANT SYSTEM
Laboratory and field tests over a period of several years have proven
that Freon Refrigerant "22" has many important advantages over Freon 1112"
as a low temperature refrigerant.
This is because the suction pressures are higher.
Therefore, ccmdensing units are capable of more refrigerating capacity
with Freon "22" than with Freon "12".
Refer to Figure 10.
