A Device for Using a Bicycle as a Motor.

I, JOIN KERWIN STEWART, of the City of Chicago (No. 158, E. Huron Street),
County of Cook, and State of Illinois, in the United States of America, Mechanical
Engineer, do hereby declare the nature of this invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:
:
The purpose of this invention is to provide a simple appliance by which a
bicycle may be utilized as a motor for driving light tools, which may be operated
by a flexible shaft. It is shown as applied to an ordinary horse clipper or shearing
tool.
In the drawings.―
Fig. 1 is a perspective of a bicycle mounted in connection with my motor
attachment, the latter being connected to a shearing tool or clipper. Fig. 2 is
a direct edge view of the rear standard and friction pulley and bearings, and
connection by which power is derived from the bicycle drive wheel.
Fig. 3 is a side elevation of the parts shown in Fig. 2.
Fig. 4 is a section at the line 4-4 on Fig. 3.
A bicycle of any ordinary construction, of which A is the rear or driving wheel,
and B, the front wheel, is mounted on supports which take the drive-wheel off
the floor or ground. For the forward wheel, I provide a box C, open at the top,
so that the forward wheel may be inserted into it, forming a case or pocket for
said wheel, merely for the purpose of steadying the bicycle. This may be dis-
pensed with. The rear wheel is mounted upon a standard D, which comprises
two uprights 11,D', which, at their upper ends respectively, are provided with
suitable seats Do Dio for lodgment of the rear axle or its bearings. Between the
two standards ). D₁, which are joined at the bottom by the cross-plate D², I
pivot the lever frame E, in whose outer or swinging end there is journaled a
friction pulley F. G is a spring, which is secured in any suitable manner so as
to react upon the lever frame E, with a tendency to hold the friction pulley F
upward against the periphery of the drive-wheel A of the bicycle. To one of the
bearings of the pulley F, in the lever frame E, the casing H¹ of the flexible
shaft His attached, while the rotating element or shaft, proper, H, is suitably
coupled to the end of the axle f of the pulley F, which protrudes through said
bearing E for that purpose. To the remote end of the flexible shaft, a clipper
or other tool may be attached to be handled by an operator. It will be under-
stood that the bicycle being mounted in the ordinary manner for riding, and
operated by the pedals and the driving connections in the usual manner, drives
the flexible shaft and the tool attached thereto, which, for some purposes, may
be handled by the rider who furnishes the power, but which will ordinarily be
handled by a second party.
Having now particularly described and ascertained the nature of this said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-

1. The employment of a bicycle as a motor by means of a support for the frame

adapted to take the driving wheel clear of the floor; a pulley arranged to be
brought into peripheral contact with the tire of the driving wheel, and a flexible
power-transmitting shaft driven by the pulley.
2. In combination with a bicycle, a pocket or case for the forward wheel; a
standard for the driving wheel adapted to take it out of contact with the floor
and afford stable support for its bearings; a friction pulley mounted in peripheral
contact with the tire of the driving wheel, and a flexible shaft driven by such
pulley.
3. In combination with a bicycle, a standard upon which the driving wheel bear-
ings are adapted to be lodged, said standard being arranged to support the bicycle
with its driving wheel clear when the bearings are thus lodged, an oscillating
frame pivoted to the standard; a pulley mounted thereon at its free end; a spring
tending to hold the pulley in contact with the periphery of the wheel, and a
flexible shaft driven by the pulley.
4. In combination with a bicycle, a standard upon which the driving wheel
bearings are adapted to be lodged, arranged to afford stable support for the bicycle
with its driving wheel clear when thus lodged; a friction pulley mounted on the
standard and arranged to bear against the periphery of the wheel; a flexible
shaft having its casing coupled to one bearing of the friction pulley and its
rotary element coupled to the shaft or axle of the pulley, and a tool carried by the
flexible shaft at its free end.
