mental Principles.

Living up to their reputation oI
being creators Of advanced motol
cars the Cole Motor Car company
introduce, the Model 500 with 4
added fe6nsments. Instead OF being
A new model, this car - an evolution
Of five years manufacturing and en-
gineeFing concentration on the int
pfoyement OF car which was fun
damenillly right,
The most important OF the A.
feiinements aud improvements are;
Constant clearance pistons, new
frame. new breaking system; clutch
that operates with the touch OF the
footi thermostalie control OF engine
temperature; adjustable spring
shaekles. spring mounted radiator,
new radiator tic bar re-designed oil
pump and timing gears: new rear
axle: new front fender construction;
special provision 20 prevent squeaks
between metal parts and body: and,
in addition, large number OF spe-
eial features which may be added 10
this model al a slight additional cost
which were not available oil previous
models.
Piston Big Advantage.
The constant clearance piston is
another contribution 10 the advance
ment OF the motor car in that II is a
perfected non.slap. non-stick alumni
mum piston. The superior advantages
OF aluminium are universally accepted.
providing its excess expansion ten
denotes can be overcome and
handled. The Cole engineers have
handled this problem in a very SIM
pie way.
Above the point where the clear
anoe is to be kept constantly at two
e-ihousandths OF an inch slot
was cut completely through the pls-
ton and this slot diverts the heat
from the piston head into the low
sides OF the piston where there is
plenty Of room for expansion. The
natural elasticity OF the metal does
the rest. The engine operates silently
and smoothly as the pistons auto
matically conform to the cylinder
walls at all degrees of temperature,
maintaining always the proper clear
snce.
Tested on Speedway.
Three stock 800 Aero-Eight cars
were taken to the Indianapolis
Motor Speedway and put through a
series of acceleration tests ranging
up to 60 miles an hour. The motors
were then dissembled and all pistons
changed, no one piston being re-
turned to its original cylinder. The
cars were then run through their
PAGES again, and it was found that
the variation between the timing OF
the runs with the factory installed
pistons and the mixed up sets was
only three-fifths per cent. At no
time was there any sign Of slap
ping or sticking.
In order to emphasize the i'm
provement in the performance of the
engine the results of an acceleration
test are noted. In this test the fol- |
lowing figures were made: From a
standing start to 50 miles an hour
in % 2-5 seconds, from three miles
an hour to 40 in 10 As seconds and |
from 10 miles an hour to 50 in Is
seconds.
In the brake test the model 800 |
has set a new standard of braking
efficiency which has not, heretofore
ever been equalled. At the rate of |
Is miles an hour the car was stop
ped in So $500 feet or five better
than any other car; at 40 miles an
hour it was stopped in l55 feet or
13 feet shorter; at 50 miles an hour
only 17S feet was required, which is
So shorter than the average high
class cars.
