New Models Thoroughly Test
ed at Indianapolis
Race Track.

Living up to their reputation OF being
creators of advanced motor cars. the
CclE Motor Car Company introduces the
model $50 with forty-two added refine
ments. Instead of being a new model
this car is an evolution of five years
manufacturing and engineering concen-
tration on the Improvement of car
which was fundamentally right
The most important of the forty-two
refinements and improvements which
are included in this model $50 are: con-
stant clearance pistons, new frame. new
braking system clutch that operates
With the touch of the foot; thermostatic
control of engine temperature; adjust
able spring shackles spring mounted ra-
diator; new radiator tie bar, redesigned
oil pump and timing gears; new rear
axle; new front fender construction;
special provision to prevent squealls be-
tween sheet metal parts and body; and,
in addition, large number of special
features which may be added to this
model at a slight additional cost which
were not available on previous models.
The constant clearance piston as used
In the model 500 is another contribution
to the advancement OF the motor car in
that it is perfected non-slap, non-sticS
aluminium piston. The advantages of
aluminium are universally accepted pro-
can be overcome and handled. The Cole
engineers have handled this problem in
a very simple way.
Above the point where the clearance is
to be kept constantly at two one-thol-
sandths OF an inch slot was cut COM
pletely through the piston, and this SLOT
dverts the heat from the piston head
into the low sides OF the piston. where
there Is plenty of room for expansion.

end smoothly as the pistons automatic
ally conform to the cylinder walls at ali
degrees of temperature, maintaining al
ways the proper clearance.
Three stock $50 Aero-Eight cars were
taken to the Indianapolis Motor Speed
way and put through a series Of accel-
Grafton tests ranging UP to sixty miles
an hour. The motors were then dissem-
bled and all pistons changed. no one pis-
ton being returned to its original cylin-
der. The cars were then run through
their PAGES again, and it was found
that the variation betwene the timing of
the runs with the factory installed pis-
tons and the mixed up sets was only
three-fifths per cent. At no time was
there any sign OF slapping or sticking.
In order to emphasize the improve
r,ent in the performance of the engine

noted. In this test the following figures
were made. From a standing start to
fifty miles an hour in 22 2-5 seconds,
from three miles an hour to forty in
16 As seconds and from ten miles an
hour to fifty in IS seconds.
In the brake test the model $50 has
set a new standard of braking efficiency
which has not heretofore ever been
equalled. At the rate Of twenty-five

was stopped in 135 feet: at fifty miles
an hour 17S feet was required.
The temperature of the engine Is
maintained uniform by the use of
thermostat valves placed on the water
outlets OF the two blocks OF four cylin-
ders. These thermostat valves remain
closed until the temperature OF the
