| BILE helical or herring bone form of
| teeth is used not only on the spur
gears in the transmission but on all
| bevel gears in aXles and in wheels.
For the purpose of cutting these gears,
special machinery has been designed,
showing that no talent or expense has
been spared to make this wheel far
superior in design, material and con-
struction to anything which has thus
far appeared in the motor-truck in
dustry.
NEW COMPENSATING DEVICE
Instead of the usual differential, a
compensating device is placed in the
hub of the vertical bevel gear. This
compensation permits the wheel TO coast
ahead OF the power in either direction
but only ahead of the power. 1t abb
solutely prevents the wheel running
backwards down hill when the power
is in forward gear-and in coasting
down hill the wheel can be stopped
either by the reverse gear or by the
brakes. The ability to coast ahead of
the power enables the outer wheel on
a curve to run faster than the inner
wheel, q result which Is accomplished
in the ordinary vehicle by the differ
entail. The use of the compensation has
resulted in applying all the power
where most needed; viz, at the peri
phery of that wheel which can do the
work. If three wheels are in soft
spots and only one on firm ground,
the whole power of the engine Is con-
centrated on the one wheel which can
exert traction. Owners and drivers
will appreciate the advantage of this
fact where the truck is to be used on
soft or muddy roads, through snow, or
over icy pavements.
The fact that the hub does not ro-
tate but turns about a verticle center
line through the wheel makes possible
the steering of the driven wheel, and
renders the steering much easier and
the steering mechanism less suscepti-
BILE to Jars and jolts than in the case
of the ordinary truck
The design of the wheel permits of
the use of the western brake which
delivers an enormous retarding effort
to the wheel with the application of
very small power. The brakes are op-
Grated either mechanically or by air,
at the option of the owner, a small air
pump and tank being furnished as part
of the equipment If so desired. If air
brakes are used, each brake is piped
separately so that in case one or more
of the brakes are out of commission
there still remains sufficient braking
effort to control truck under normal
operating conditions.
The MseGorge patents have been ac-
quired by the Cleveland Motor Truck
Manufacturing company, corporation
recently formed with capital of
$25O,O00 which will manufacture COM
mercial trucks using the McGeorge
wheel. This company has retained Mr..
McGeorge as chief engineer. The di-
rectors of the company are H. w.
Woodward, president; r. H. Sharp,
vice president and manager; w. M.
Hager, secretary; A. w. Johnston,
treasurer, all of Cleveland, and DR..
Edwin Leonard, jr.. of New York. The
company will manufacture eight mod
els of commercial vehicles varying in
capacity from 1000 pounds to six or
seven tons. Four Of the models will
be electrical and four gasoline. A
factory has already been secured and
demonstrating cars are being con-
structed. The company hopes to have
a complete line of models ready for
the market at very early date.
