This illustration shows the continuous carburizing furnaces used for case-hardening
such parts as transmission gears, rear axle ring gears, etc. The work is
pushed through one of these furnaces at regular intervals and requires 12 hours
for the complete "cooking" process. After parts are removed, they are quenched
in oil or other solutions to harden them.
Heat-treating Packard parts is an exact science. Temperatures are used in the
Packard plant from 30? F. to 2800? F. and methods of measuring and accurately
checking these temperatures are most modern.
Heat-treating Packard parts should be interesting to your prospect. The linen
collar you have on would not look or wear so well if it were not first starched
and then heat-treated with modern machinery. Neither would our mother's pies be
so digestible if the dough in the crust were not heat-treated.
Given the same ingredients, three cooks make three different kinds of pies -
depending upon their experience, judgment and knowledge of the art of cooking.
Apply this same truth to steel, and here again, Packard having originated much
heat-treating machinery and many heat-treating processes does the job better.
Again, this is another pocketbook reason for your prospect.

This illustration shows the instruments for recording temperatures used on continuous
heat-treating furnaces.
A line is drawn on each of the charts throughout each run and this accurately
records the temperature.
Equipment of this type is used on all heat-treating furnaces, enameling ovens,
paint drying ovens, core ovens and all places where accurate temperature
control is necessary.
This equipment, besides drawing a chart showing the temperature, also automatically
opens and closes either the gas or oil used for firing when the temperature
becomes either too high or low.
They are so accurate, that at temperatures of 1600? F. there is a variation of not
more than plus or minus 5? F.
You would not think much of a hospital where the temperature thermometers used
with the individual patient were not carefully checked by pre-established standards,
based on years of experience. In the Packard heat-treating department, they are
just as careful with the instruments used for recording temperatures as a hospital
superintendent is of the instruments used by his staff of physicians.
There is a crisis period in the heat-treating of every metal. If temperatures
are permitted to go beyond certain limitations, the molecules that m?*;e up this
metal break down, lose their efficiency and become worthless. We leave as little
as possible to human opinion and conjecture. Every batch of material has its own
chart. This accounts for the many numbers found on even the smallest parts.
These charts are filed for reference and constant study. Here, too, your Packard
product is protected to the maximum.

On a 400 acre site a few miles from the factory, Packard has built the most
unique proving ground in tb8 world of industry. Besides containing a 2fc mile
long, 50 foot wide, banked turn, oblong race track, this proving ground contains
a perfect airplane landing field.
-Equipment on this experimental speedway consists of everything from a towing
dynamometer to a testing laboratory. Proving Packard cars built from 29 years
of recorded experience calls for a different type of track and accessories than
|if. Packard were building cars in a wide range of price classifications.
As of today* a certain number of finished Packard cars are taken from the assembly
line each month and placed in test at our proving grounds. These tests run anywhere
from 5000 - to 50,000 miles and are compressed in as few as 20 days. By
working three shifts of men, cars record mileage in excess of a year's average
driving in a comparatively few hours.
|This proving ground permits actual measurements for wear on cylinders, pistons,
bearings, valve springs, transmission, universal joints and rear axles, scientifically
and accurately.
The Packard Proving Ground is a gigantic "crime detector." Through this investment
your prospect is assured of simplicity in design, durability in manufacture
and economy in operation of his Packard purchase.
This picture shows a special Packard Eight phaeton traveling at a speed in excess
of 100 miles an hour.
