SPRING WHEEL BEING TRIED OUT

In Success Of Venture.

any mechanic pronounced IL anything

two ils have defective teeth. Two i

will easily break this metal. Then
II. in addition to this movement Just
described, we drive the wheel by the
aid OF the spring we subject me
snrIne 20 another motion, that OF ten
sion. or a twisting motion, Ihese
various motions readily induce mole
cnlar action which means disintegra-
ton and crystalization. But the Nc
Cord Spring Wheel IS built on an en-
urelv different principle; principal
as different from any other wheei as
happiness * different from daylight.
In this wheel the springs are attach
Cd only 10 the rim; and along the rim
unattached except at the top end a
driving lug contacts with the other
end and congresses the spring Wheh
the vehicle Is in motion, or When
strain or shock comes. As IT VIII De
readily seen that we drive against IN
stead OF with the spring. This re-
lieyes the spring OF the injurious ell
feet OF tension motion. BY attaching
our spring By one end only we relieve
the spring Of the motion OF tension
eliminating the strains of tension ana
torison and subjectmg spring To
the strain Of compression only is the
solution OF the spring wheel problem
This we have achieved.
The second problem awaiting soiu-
ton was to find medium OF shock
absorption that was not only rigid
enough 10 withstand the strain OF load
and shock. but resilient enough
~ receive and absorb the slight
est OF shocks. Thus the spring
had TO be both rigid and resilient
q seeming insuperable obstacle. But
MIR. McCord solved the problem by
using a combination, or system, con
sisting OF two, three, four or more
springs SO constituted and arranged
as TO receive the strain or shock
in the exact ratio or It's intensity. Inc
initial strain coming, Of course, on
spring No. j. when the strain became
greater spring No 2 became automat-
ically employed, and this process con
tinued through the entire combina-
ton. 1t can be readily understood
how the strain would merge gradual
~ and gently from one spring into
another. producing the exact erect
of a boat riding on a wave OF an un-
duaulating glide instead Of bounc-
ing, jarring effect like tat OF the
pneumatic tire.
The third problem was TO build
a wheel that could not possibly dish
from the effects OF what is called the
ana or side, thrust. This thrust oc-
ours when the car turns a corner
rapidly or slow.
MIR. McCord solved this problem by
constructing the wheel Of all-steel,
including two steel discs dished or
shaped so that the end or side thrust
could not possibly dish the wheel.
Having overcome every objection
able features OF spring wheels and
having positively demonstrated the
McCord Spring Wheel 70 be not only
a mechanical marvel. but eminently
practicable Mr. McCord arranged
with the Republic Truck Co. OF Al
ma, Michigan 10 give the wheel a
perfect tryout This IS now being
made, and a report is expected with
in the next three or four weeks.
Should the report be OF a favorable
nature the Mccord Spring Wheel Co
will Immediately begin the construc-
ton OF their wheel commercially. II

in easy reach Of warkets and ma
terial.
