WHAT Do YOU KNOW
ABOUT AN AUTO, HUH?

For those not familiar with the
names of automobile parts, the follow
ing may be of interest:
Accelerator-A pedal placed within
reach of the operators foot, by which
means the governor action is opposed,
effecting a partial or complete opening
of the throttle, according to the pres
sure eXerted upon 1t.
Brake shoe (also called the brake
banda flexible part of the brake.
Brake drum-That part of the brake
upon which the brake shoe binds.
Cam shaft-ROtates at half the speed
of the crank shaft, and by means of
the cam actuates the valve mechanism.
CANA rotating part of the motor,
irregularly shaped and rotating about
center different from its own. which
actuates the valve mechanism.
Carburetor-A mechanical device for
mixing gasoline with air in proper pro-
portions, supplying highly explosive
mixture of gas to the engine.
Chassis (also called the running gear)
That part of the car upon which the
body is mounted.
Check valve-A valve placed in pipe
to prevent the return of gas or air
pressure or the flow of liquid.
Clutch-A clutch is a device permit
ting the engagement and disengage-
ment of the driving mechanism from
the motor.
Combustion chamber-That part of
the cylinder not swept by the piston in
which the gases are confined.
Connecting rod (also called the pis-
ton rod)-Connects the piston with the
crank shaft.
Crank case-That part of the motor
containing and inclosing the crank
shaft.
Cut-out-A device by which the ex-
ID fIr1rr 10
gas to escape without going through
the mufher.
which is swept by the piston.
Crank shaft-An irregular shaft
which, by means of the connecting rod,
| transgorms the reciprocal motion of the
/ piston to rotary motion.
Cylinder jacket-A space around the
outside of the cylinder which is filed
with cooling water.
/ Differential-A set of gears. the pur-
| pose of which is to so distribute the
/ power transmitted through them as to
/ allow the driving wheels of car TO
/ travel at different speeds, according to
/ the resistance with which they meet
/ in passing the road.
Exhaust pipe-A pipe conducting the
+ exhaust gas from the cylinder.
Fly wheel (also called the balance
/ wheeD-A heavy wheel fastened to the
/ crank shaft, which by its momentum
continues the rotation Of the crank
shaft through the idle strokes of the
piston.
Exhaust valve-That part of the mo-
tor which closes the opening through
which the gas is emitted.
/ GoVernor-An attachment to auto
matically regulate the speed of the en-
gine.
Inlet pipe-A pipe connecting the
/ carburetor with the inlet valve cham
/ Der.
/ Union-A fitting by means Of which
+ two pieces Of pipe can be joined 10
/ gether and be readily taken apart With
/ out unsCreWing the pipe.
/ Mufher-An attachment for sllenclnS
! the noise of the exhaust.
Multiple engine-An engine having
more than one cylinder.
Piston-That part of the motor work
/ ing within the cylinder upon which the
/ expansive force OF the gas acts
Piston -EXpansible rings fitted
to the piston, the object of which is to
make a gas-tight joint between the
/ cylinder wall and piston
Planetary transmissiOn-A transmls-
/ sion in which the gears revolVe around
/ the shaft, at the same time revolving
| on their own axis.
Selective t~pe of transmission-A
/ transmission in which the sliding mem
/ Der or members do not pass through
the gears in which they are engaged
/ (For example, a change can be made
from high to low gear, or from low to
high gear, without passing through the
intermediate gears.)
Sliding-gear transmission-A trans
mission in which a gear or number Of
gears capable Of being moved along one
shaft makes engagements with other
gears on a shaft parallel to it.
