Except for the motors one detects
very little different in the chassis of
the Four and Eight Olds cars, both of
which weigh less than 2S0O pounds
Construction of the eight-cylinder
motor requires third cross member
in the frame and there In also a slight
variation between the models in the
designs of the rear axles. Both en-
ploy full floating features and the
Hotchkiss drive, which provides torque
through the rear springs; in the eight,
however. the axle shafts are remov-
able by taking out bolts on the wheel
hub flange, while in the four a small
collar on the side of the dAfferential
housing must be disconnected.
The four cylinder motor Is of the
valve head type, 31a by E inches,
developing 80 h. p. and equipped with
metal silencing cap which complete
ly encloses the exposed valve rocker
arms
The eight with bore and stroke di-
mansions 27s by AZ inches, and devel-
oping 40 h. p. is an extremely inter-
esting Vtype design, incorporating
many novel features of construction
The crank case is divided vertically
and cast integral with cylinders, con-
sequently the motor is cast in two
sections Such a design is necessarily
simple and facilitates assembling and
making adjustments. Cylinder heads
also are cast four en- bloc and, carry
ing the printing cocks and spark
plugs, are removable. giving quick ac-
cess to the valves and pistohs. Hand
hole cover plates located between the
two rows of cylinder blocks give the
same easy access to valve tappets.
Very Compact Desig h.
A single drop forged cam shaft, con
tanning the cams, operates the valves
for both sets of cylinders. The valves
are set at a slight angle to the cylind-
er walls which makes very compact
design in the combustion chambers.
Valve filters are contained in two
brack cts, on each side of the motor,
and can be s-assembled in unit from
the motor.
The crank shaft, a heat-treated, high
carbon steel drop forging is consider
ably shorter and larger in diameter
than standard practice ana 10 this the
yoked connecting rods arc bolted and
set at the customary 90-dcgrec angle.
Aluminium die cast pistona are used
being reinforced inside the head by a
web running parallel with the wrist
pin, and relieved at the ends OF the
wrist pin and near the bottom to
eliminate as much friction from the
cylinder walls as possible. Each piston
has four concentric cast iron rings
three serving rs compression rings and
one as scraper ring, to clean the
cylinder walls OF superfluoua oil
Electrical equipment consists of a
single unit Delco system with starter,
generator and distributor each mount
ed separately and Independently of the
other two.
The four and eight cylinder Spas
senger touring cars in the Odds ex-
hibit are practically identical in APP
pearance from the radiator back. The
radiator of the eight is new adapta-
ton, and Is not unlike the radiators
seen on some of the high grade Euro
pean machines. The convertible type
roadster, also shown, is mounted on
the standard touring car chassis. BY
opening a hinged double door. which
covers the large baggage ocker the
rear compartment can be transformed
into a well cushioned and altogether
comfortable seat for two people.
