Hill Climb

A big Gearless Six has arrived in Los
Angeles and is attracting considerable at
tention by the excellent manner In which
It runs.
It differs from the average type of
automobile in that 1t has no gears suci1
as are usually used to change the speed
tof the machines. Instead of having the
IEelective type of transmission that is in
use on q very large percentage Of the
secs models a novel device has been utll-
lzed that eliminates all of the unpleasant
Jerking that Is ordinarily felt when =
machine is thrown into the high gear.
The principal on which the gearless
transmission works is very simple but
somewhat difficult to explain lntelllgently
on account of the technical terms neces-
eary to distinguish the various parts of
the mechanism.
Fastened to the crank shaft is a driving
cone, upon the suface OF which revolves q
Rage Of five ball bearing rollers conical in
korm and made Of special fiber. Sur
pounding the cage Of rollers Is cup cone
INTO which the cage Of rollers fits.
The rollers, cone and cone cup are
forced together by a spring to prevent
Mhe surface Of the rollers slipping on the
faces Of the cone and cup. A friction
clutch that engages with the clutch cup,
ITO which is fastened the cage of rollers
and solid jaw clutch that engages with
Aeither the cage of rollers of the cone cup
completes the mechanism.
\ To Get Low Speed
To get low speed forward the jaw clutch
lie thrown backward to engage with the
bcage of rollers and the cone cup is pre-
vented from turning by the application of
IA friction band operated with foot
Eedal
| AS the engine turns the rollers are set
In motion and the cage is forced to revolve
INSIDE the cone cup, which remains sta
tionary.
AS the cage of rollers is connected
direct with the driving shaft by engaging
ahe Jaw clutch the power Is transmitted
TO the rear wheels. To reverse, the cage
of rollers is held stationary by friction
band and the jaw clutch thrown back 10
engage with the cone cup.
This allows the motion to be transmitted
through the cage of rollers from the cons
on the crank shaft to the cone cup en-
gagged with the line shaft, but the motion
rs reversed.
To get to high the friction clutch is
thrown in, while the lever Is set for low
rpeed forward and both of the friction
lands are released. which allows the an
tire transmission system to revolve as a
unit with the crank shaft and has the
effect of making the crank shaft and line
ehaft direct and solid.
Trouble Avoided
While running on high as soon as the
brake pedal is pushed down the high speed
IS automatically thrown out. thereby
avoiding great deal of possible trouble.
While the efficiency of the transmission
was being demonstrated the car was
brought to stop by simple pressure IF
The brake pedal alone and started again
by throwing the machine directly into
tigh. and from the easy and gradual
manner that the car moved forward it
seemed possible that such could have
been the case, as there was absolutely no
jerk or jar as the car picked up speed.
The design and manufacture of the
transmission assures good service and re-
duces the danger from breakage to a
minimum. There is no such thing as
stripping a gear. nor can the most anna
flourish driver put on a brake with the
engine connected up, as it disengageg
automatically. The operation is so simple
hhat it appeals strongly to the man or
woman who has a fear of grasping the
wrong lever or pushing the wrong pedal.
las a hill climber the Gearless Six is
wonder, and great things are expected of
1t at the Thanksgiving day contest.
The average steep hill can be taken .,
high, and when the change is made to
Aow all it is necessary to do is to press
one pedal and the change is made so
Smoothly that those in the car are unable
ITO tell when it occurs from any change in
fhe motion of the car other than that Of
speed
AS the friction bands are held tight by
khe locking of the foot pedals there is no
Eelipping, as there often is in the usual
Eclutch that engages by spring pressure
and releases from pedal pressure.
There is no doubt but what the new
style of transmission will leap into imme-
hiate favor, as 1t overcomes nearly all of
pthe objections to the present popular
sBelective type.
