Improvements in the Method of Attaching Motor Apparatus to
Cycles and other Rolling Vehicles.
I GEORGES BOIVIN, of 15 Rue des Halles Paris, in the Republic of France, do
hereby declare the nature of this invention to be as follows:-
This invention consists in attaching the motor apparatus to the driving wheel of
the cycle or other rolling vehicle and in the method of effecting this object.
The motor is fixed in a frame carrying a socket in which is supported, and
rotates, one end of the crank spindle. This socket is fixed to the corresponding
arm of the back fork of the cycle or of the support of the vehicle.
The other extremity of the crank spindle rotates in a bearing fixed to the other
branch of the fork and the wheel is fixed on this spindle between this bearing and
the frame of the motor by means of a felly forming a cover to the motor and its
various accessories such as petroleum reservoir, boiler &c. according to the type of
the motor adopted. The other hub of the wheel is loose on the socket which
supports the other extremity of the crank spindle.
In consequence of this arrangement the motor remains fixed, it gives stability to
the apparatus on account of the low position it occupies, and the action of its
working parts is effected without undue strain and vibration.
Any suitable motor may be used such as steam, petroleum, gas, electric, &c.
The space in the tire may be utilised to contain the reservoirs batteries,
accumulators, etc. necessary for the production of the motive force.

Improvements in the Method of Attaching Motor Apparatus to
Cycles and other Rolling Vehicles.
1, GEORGES BOIVIN, of 15 Rue des Halles, Paris in the Republic of France,
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 :-
This invention consists in attaching the motor apparatus to the driving wheel
of the cycle or other rolling vehicle and in the method of effecting this object.
The motor is fixed in a frame carrying a socket in which is supported and
rotates, one end of the crank spindle. This socket is fixed to the corresponding
arm of the back fork of the cycle or of the support of the vehicle.
The other extremity of the crank spindle rotates in a bearing fixed to the other
branch of the fork, and the wheel is fixed on this spindle between this bearing and

page_text: the frame of the motor by means of a hub formed on each side of the casing which
replaces the spokes and encloses the motor and its varions accessories such as
petroleum reservoir, boiler &c. according to the type of motor adopted. Oue hub
is keyed to the axle: The other hub of the wheel is loose on the socket which
supports the other extremity of the crank spindle.
In consequence of this arrangement the motor remains fixed, it gives stability
to the apparatus on account of the low position it occupies and the action of its
working parts is effected without undue strain and vibration.
Any suitable motor may be used such as a steam petroleum or electric motor
and may be single or double acting; with only one cylinder or with two coupled
cylinders, the wheel being widened in this case in consequence, and adapted to be
provided with two tyres instead of one. The transmission of the movement of the
driving axle to the wheel may take place otherwise than in a direct manner, for
example, by means of a series of toothed wheels, or otherwise.
In the accompanying drawings.
Figs. 1, 2 and 3 are side elevation, plan and end elevation respectively showing
the application of this invention to a bicycle.
Fig. 4 is a section to an enlarged scale through the axis of the driving axle,
showing the arrangement of the framing and of the motor.
Figs. 5 and 6 are detail views and
Figs. 7 and 8 show two mechanisms for transmitting the movement of the
driving axle to the driving wheel.
The piston B works in the cylinder A and to it is jointed the connecting rod C
transmitting the motion to the driving axle D. The framing E F of the motor
has secured upon it two sockets, a long one H, fixed between the two branches b bl
of the head of the fork (Fig. 5), and a short one H. The hub K of the driving
wheel is secured upon the axle D by the key a. This extremity of the axle D
turns in a bearing secured as shown in Fig. 6 between the two branches of
the head of the fork. The other hub K¹ of the driving wheel L turns freely
upon the sleeve H. An indiarubber or pneumatic tyre M of any suitable kind is
fastened upon the driving wheel, and the spokes are replaced by a metallic casing
constituting a closed cylinder with rounded edges and perforated sides, in the
interior of which the motor device is arranged.
The driving wheel L may be made in the form of a cup, the tyre forming the
edge, and the metal work replacing the spokes being all on one side. Instead of a
single tyre the wheel L might likewise receive two tyres, one on each side of the
central plane, and it may also be arranged to receive in its interior two coupled
cylinders instead of one, the spokes being in this case replaced by a central
perforated plate with a keyed hub situated in the central plane of the tyre, and by
two perforated plates each provided with a free hub turning upon the sockets H H
thus enclosing the motor apparatus.
The transmission of the motion of the axle D to the driving wheel L may be
effected in various ways. As shown in Fig. 7 the toothed wheel e keyed upon the
axle D gears with the pinion d' keyed upon the shaft c, at the other extremity of
which is secured the pinion ¹ which engages with the wheel g' made in one piece
with the hub of the casing on the left hand side of the driving wheel L, the hub of
the casing on the right hand side, if this second casing exists, turning freely upon
the right hand extremity of the axle D.
The free space between the two sides of the casing may be utilized to contain
the reservoir, batteries, accumulators, &c. necessary for the production of the
motive force.
Fig. 8 shows another method of transmitting to the wheel L the motion of the
axle D. The toothed wheel e keyed upon the shaft D gears with the pinion d
keyed upon the shaft el at one of the extremities of which is secured the pinion f
which engages with the wheel 9 made in one piece with the hub of the casing on
the right hand side of the wheel L which turns upon the fixed socket of the
framing.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
:-
1. In cycles and other rolling vehicles operated by motor apparatus, the
construction of the driving wheel with metallic plates connected with the rim.
which receives the tyre or tyres, the whole forming an interior chamber in which
is arranged a frame carrying the motor apparatus and accessories and which is
suspended from the heads of the fork by sockets which support the driving axle,
motion being transmitted to the driving wheel either directly or by a series of
toothed wheels substantially as described.
2. The improvements in the method of attaching motor apparatus to cycles and
other rolling vehicles substantially as described with reference to the drawings.
