PROVISIONAL SPECIFICATION.
Improvements in or connected with Gearing for Velocipedes.
I, OSCAR BADGE, of 302, Wheeler Street, Lozells, Birmingham, Gentleman,
do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in or connected with gearing for
velocipedes, and has for its object to lessen the resistance and give increased
leverage both by the greater length of chain used in connection with my improved
gearing and also by reason of the chain wheel which drives the back wheel of the
machine, being directly up under the seat or saddle, and by my improved arrange-
ment a high rate of speed can be more easily maintained than has hitherto been
possible.
In carrying my invention into practical effect I provide two toothed or chain
wheels mounted upon a spindle carried in suitable bearings at or near the junction
of the frame of the machine close up under the seat or saddle. One of these
two toothed wheels is connected by means of a chain to the usual tooth wheel
upon the crank axle, while I provide a second chain connecting the remaining
wheel of the aforementioned pair with the toothed wheel upon the hub of the
back wheel of the velocipede.
By this means the power which is put into the wheel, mounted upon the crank
axle, by the rider, through the pedals, is first transmitted to one of the two wheels
arranged under the seat or saddle, thereby causing the axle upon which it is
mounted to revolve and carrying with it the second toothed wheel which transmits
the power to the back wheel of the velocipede by means of the aforesaid second
chain.
According to a modified form or arrangement of my improved gearing, the
motion of the wheel mounted upon the crank axle is communicated to a wheel
arranged beneath the seat or saddle, the said wheel having in addition to the teeth
formed upon its outer edge for engaging with the chain, an inner toothed periphery,
which communicates the motion to one of two smaller wheels mounted upon a
suitable axis beneath the saddle at the top of the frame of the machine, the second
of the two smaller toothed wheels in its turn communicating the motion to the
back wheel of the velocipede.
As my invention is capable of some slight modifications, without departing
from the principle thereof, I wish it to be understood that I do not restrict
myself to materials, dimensions of the aforesaid wheels or to the precise form or
placement of the various parts constituting and forming my improved gearing for
velocipedes.

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:-
My invention relates to improvements in or connected with gearing for
velocipedes, and has for its object to lessen the resistance and give increased
leverage both by the greater length of chain used in connection with my improved
gearing and also by reason of the chain wheel which drives the back wheel of
the machine, being directly up under the seat or saddle, and by my improved
arrangement a high rate of speed can be more easily maintained than has hitherto
been possible.
In carrying my invention into practical effect, I provide two toothed or chain
wheels mounted upon a spindle carried in suitable bearings at or near the junction
of the frame of the machine close up under the seat or saddle. One of these two
toothed wheels is connected by means of a chain to the usual tooth wheel upon the
crank axle, while I provide a second chain connecting the remaining wheel of the
aforementioned pair with the toothed wheel upon the hub of the back wheel of
the velocipede.
By this means the power which is put into the wheel, mounted upon the crank
axle, by the rider, through the pedals, is first transmitted to one of the two wheels
arranged under the seat or saddle, thereby causing the axle upon which it is
mounted to revolve and carrying with it the second toothed wheel which transmits
the power to the back wheel of the velocipede by means of the aforesaid second
chain.
According to a modified form or arrangement of my improved gearing, the
motion of the wheel mounted upon the crank axle is communicated to a wheel
arranged beneath the seat or saddle, the said wheel having in addition to the teeth
formed upon its outer edge for engaging with the chain, an inner toothed periphery,
which communicates the motion to one of two smaller wheels mounted upon a
suitable axis beneath the saddle at or near the top of the frame of the machine, the
second of the two smaller toothed wheels in its turn communicating the motion to
the back wheel of the velocipede.
In order that my invention may be more fully understood, I will now proceel t▸
describe same with reference to the accompanying drawings in which
Fig. 1 is a diagrammatic view in side elevation of a sufficient part of a
velocipede for illustrating the application of this invention, and Fig. 2 is an end
view of same.
Figs. 3 and 4 are corresponding views illustrating a slightly modified form of
my invention.
According to my invention and referring more particularly to Figs. 1 and 2
I provide two toothed or chain wheels a, a', mounted upon a spindle and carried by
any suitable bearing b, said wheels being arranged at or near the junction of the
frame and close up under the saddle. The wheel a¹ is connected by chain e to
wheel w mounted upon the crank shaft, while the wheel a is connecte.l by means
of chain c¹ to the ordinary chain wheel w' carried by the hub of the back wheel, so
that upon power being transmitted to the wheel w by means of pedals and cranks in
the ordinary manner, the consequent motion is transmitted to wheel a' by chain c
thereby causing the axis upon which it is mounted to revolve and carrying with
it the chain wheel a which in turn communicates the motion to the wheel to by
means of chain c'.

suitable bearings bl a wheel to toothed upon its outer periphery so as to gear by

means of chain c with the ordinary driving wheel e of the velocipede.
said wheel w is also toothed upon its inner periphery and engages with one of
two wheels mounted upon suitable spindle and carried by a bearing 6, the second
wheel w of this pair being connected by means of a chain c to the ordinary chain
wheel carried by the hub of back wheel, so that upon the wheel w being
revolved in the usual manner the motion is transmitted by means of chain c to the
internally and externally toothed wheel w³, which in turn communicates the motion
to the two wheels carried in bearing 63, the second wheel w³ of which is connected
by means of a chain c¹ to the wheel w¹ on hub of back wheel, and by this means
drives the machine.
The bearings for carrying the wheels arranged at or near the top of the frame
may be of any suitable and well known construction, and the frame of the
velocipede may be slightly altered in design as required, and if found necessary.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improvements in or connected with gearing for velocipedes, substantially
as herein described and shown and for the purposes specified.
2. In combination with the ordinary crank wheel w and hub chain wheel w', the
arrangement of two toothed wheels such as a, a¹, carried in a suitable bearing at
or near the top of the frame f, and connected to the said wheels w, w, by
chains c, c, substantially as herein described and showu with reference to Figs. 1
and 2 of the accompanying drawings, and for the purposes specified.
3. The modified form of the invention substantially as herein described and
shown with reference to Figs. 3 and 4 of the accompanying drawings, and for
the purposes specified.
