Tricycle Manufacturer, for an Invention of "IMPROVEMENTS IN THE
CONSTRUCTION OF WHEELS FOR TRANSMITTING MOTION IN VELOCIPEDE

of the Commissioners of Patents on the 17th December 1880.

"IMPROVEMENTS IN THE CONSTRUCTION OF WHEELS FOR TRANSMITTING MOTION
IN VELOCIPEDE GEARING, APPLICABLE ALSO FOR OTHER PURPOSES."
This Invention has for its object the construction of wheels for use in tricycle or
other velocipede gearing, and has reference principally to an intermediate wheel
used for transmitting motion from or between toothed wheels to the driving
wheels, but which is capable of being applied to other purposes in machinery
where it is desirable to reduce friction in gearing. It consists in a wheel or
pulley, the periphery of which is recessed and constructed with a suitable flange.
A similar loose annular flange or ring is capable of being secured by countersunk
bolts or other means of fastening on its opposite side. Suitable bushed holes or
depressions are drilled or formed at intervals in said flanges to receive the axes or
pivots of balls, which gradually taper to a truncated conical shape at each end,
formed of steel, phosphor, bronze, or other suitable anti-friction metal, the pivots
of which revolve in case hardened bushes of the said flanges or rims, the loose
flange allowing of their being inserted into position.
This wheel being placed in gear with a suitably toothed wheel which is driven
by the pedals serves to transmit motion to another suitably toothed wheel actuating
the driving wheel, thus dispensing with all dangerous chain gearing at present in
use, and affording an easy rolling motion with a nominal amount of friction.
Suitable channels could be formed in the wheel to lubricate the rolling surfaces.
It is obvious that the details could be varied without departing from the principle
of my Invention.

Suitable channels could be formed in the wheel to lubricate the rolling surfaces.
It is obvious that the details of my Invention might be varied without departing
from the nature thereof.
And in order that my Invention may be more clearly understood and more
readily performed, I will now proceed to describe the same by reference to the
accompanying Drawings.
Figure 1 shews a side view (partly in section) of my wheel.
Figure 2, an end elevation (partly in section) of the same.
A few only of the balls or rolling surfaces are shown.
A is the flange forming part of or carried by the wheel body.
B, the loose flange screwed or bolted to the rim at intervals.
C, the peculiarly shaped balls or rolling teeth working as before described.
It will be found in practice that by the employment of my Invention friction is
much reduced, as compared with rigid gearing.
Instead of the herein before shown plan two of these wheels may be placed with
an ordinary spur wheel intervening.
Having now particularly described and ascertained the nature of my said
Invention for "Improvements in the Construction of Wheels for Transmitting
Motion in Velocipede Gearing, Applicable also to other Purposes," I would have it
understood that what I desire to claim under the hereinbefore in part recited
Letters Patent is,-
Firstly. The improved wheel furnished with the special solid ball or friction
rollers, as and for the purposes described.

page_text: Secondly. In combination with the wheel body and rollers, the loose annular
flange or ring, as and for the purposes described.
In witness whereof, I, the said Joseph Radges, have hereunto set my hand and
seal, this First day of June, 1881.
