Improvements in or connected with the Driving Mechanism of Cycles
and other Wheeled Vehicles.
We, JAMES RICHARD SHAW, of 69, Holyhead Road, Handsworth, in the County
of Stafford, Architect, and FREDERICK THOMAS COTTON, of 69, Thornhill Road,
Handsworth, in County of Stafford, Silversmith, do hereby declare the nature of
this invention to be as follows:-
Our invention has for its object improvements in the method of driving the hub
of cycle or other wheels by spinning action, and in order that our invention may
be clearly understood and easily carried into practical effect we have appended
hereunto a sheet of drawing upon which we give an example of its construction:
but it will be understood that the formation or design may be varied to suit the
particular purpose to which it is applied.
The barrel of the hub lettered A on drawing is similar to those in present use
with the exception that a steel-toothed collar lettered B is sweated onto the outer
flanges to take the clutch action C in the spinning wheel D.
To this spinning wheel is affixed the steel bevel gear wheel E.
A bevel gear wheel F of similar pitch to E is screwed on and affixed with lock
nut G to a hollow spindle H. Around this hollow spindle H revolves the spin-
ning wheel A running on ball bearings J.
The steel bevel gear wheels E and F above mentioned are connected with a
gear wheel K of similar pitch; the bearing of this gear wheel K being attached
to a steel bracket L carrying the gear case.
In the centre of the hollow spindle H is the usual solid spindle M fitted with
ball bearings N. The spinning wheel 0,at the other end of the hub is attached
to the hollow spindle H, without the intervention of the bevel gear, and fixed with
lock-nut P.
By the mechanism above described the action of unwinding the cord or chain
from the one spinning wheel D winds up the corresponding cord on the spinning
wheel O and vice versa.
These wheels are driven in the following manner. The pedal is on a lever with
an up and down motion, having its bearing or fulcrum on each side of the back
frame of the cycle. The length of the lever on either side of the fulcrum being
in the proportion of three to one. To the end of the short bent arm of the lever
is attached the cord or chain which imparts the spinning motion to the hub;
the other end of the cord being attached to the spring wheels D and respectively

page_text: (Figure 1), one of such levers being arranged on each side of the bicycle. The
levers are pivotted at m and each has an ordinary pedal mounted on the free or
outer end m; the opposite end of each lever is attached to one end of the cord
or flexible driving connection G which is, by the action of the lever, alternately
wound upon and unwound from the spinning wheel E or E¹. Power is trans-
mitted from the lever M to the spinning wheel E only on the down stroke of the
pedal end m¹ of such lever; the return or up-stroke of the pedal is effected by the
down stroke of the opposite pedal acting through the mechanism hereinbefore
described.
We do not limit ourselves to the hereinbefore described form of clutch or auto-
matic engaging and disengaging connections between the spinning wheels and the
cycle wheel hub or parts secured with such hub, but employ other suitable types
or forms of such clutches or connections.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. The improvements relating to the driving of cycles and like machines by the
action of spinning wheels, comprising the combination with the hub of the cycle
or other wheel of means whereby the movement of one of the spinning wheels
in the one rotary direction automatically produces a movement of the other spin-
ning wheel in the opposite rotary direction, substantially as and for the purpose
described.
2. In combination with a cycle or other wheel hub A having automatic attaching
and detaching or clutch like connections with the wheels E and E¹ which are
rotated by the movement of levers as M transmitted through the cords or flexible
bands G, the use of a sleeve as C disposed between the hub A of the said cycle or
other wheel and the axle 1), one end of the said sleeve being in direct attachment
with the spinning wheel E¹ and the opposite end connected with the spinning
wheel E through the gearing wheels J, K, and L, substantially as and for the
purpose described and as illustrated.
3. Driving mechanism for cycles and like machines, constructed and arranged
substantially as described and as illustrated.
