We JAMES CAREY of 17 Great Hampton Street Wolverhampton in the County
of Stafford Engineer and SAMUEL DORSET of 8 Perry Street, Wolverhampton
aforesaid Engineer do hereby declare the nature of our invention for IMPROVE-
MENTS IN THE DRIVING GEAR OF BICYCLES TRICYCLES OR ANY OTHER MACHINERY
WORKED BY MANUMOTIVE POWER to be as follows:-
Improvements in the driving gear by using a chain connected with a lever on
to the driving wheel and not being a rotary motion such motive power and action
being obtained by the use of a double spindle (that is one spindle running through
another) and wheels placed in the positions as shewn on the accompanying
drawing.
And we claim more particularly the use of gearing for winding or drawing the
action back and also the use of the hollow spindle.

other Machinery Worked by Manumotive Power.
We, JAMES CAREY of 17 Great Hampton. Street Wolverhampton Engineer and
SAMUEL DORSET of 8 Perry Street Wolverhampton Engineer both being in the
County of Stafford do hereby declare the nature of our invention for IMPROVE-
MENTS IN THE DRIVING GEAR OF BICYCLES, TRICYCLES OR ANY OTHER MACHINERY
WORKED BY MANUMOTIVE POWER and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
:-
:
The object of this invention is to obtain increased power or speed by means of
levers, instead of the ordinary rotary motion, and to avoid dead centres.
The invention when applied to a Bicycle will be clearly understood by reference
to the accompanying drawings. Fig. 1 represents a side view of the lower portion
of a fork of a Safety Bicycle. Fig. 2 a plan of same. Fig. 3 a front view of same.
Fig. 4 shows another arrangement in which the same principle is carried into
effect: Fig. 5 being an enlarged view of same.
To the bottom of the fork of Bicycle a there is jointed a lever 6 to which the
pedal c is attached at the other end. At an intermediate position d a chain e is
attached which works over a drum f fixed to each flange of the hub g, the other
end of chain being secured to the said drum. Each drum contains a ratchet and
pawl arrangement i, the ratchet being attached to the hub and being driven
alternately. Through the centre of the hub there is passed a spindle; which
works freely inside the hub. The extreme end of the spindle is secured to the
bevel wheel k which revolves with it the other end of the spindle being secured
to one of the two drums on which the chains work, as shown in Fig. 1. 2 and 3.
The bevel wheel thus communicates a reverse motion to the other pedal lever
through the action of the bevel wheels and m. The action of the machine is a
follows The lever b being pushed down by the foot, the chain pulls the drum
which is on that side round with it, and so propels the Bicycle. The small bevel
wheel m at same time causes the companion wheel k to revolve in a contrary
direction, and this being attached to the spindle j winds up the pedal lever on the
other side of machine and when the opposite lever n Fig. 2 is pressed down the
other corresponding lever is raised in a similar manner.
Figures 4 and 5 show another method of winding up the returning pedal lever,
the three small bevel wheels in figures 1. 2 & 3 being replaced by the small roller o
and the chains p and r. which work on the continuation of drum f the chain being
crossed as shown to reverse the motion. When the lever is pushed down by the
foot the drum f causes the small roller to revolve and the motion is communicated
by means of the chain p to the central spindle j which then acts in the manner
described in Figures 1. 2 & 3.
Of course it is evident that the pawl and ratchet arrangement can be replaced
by any other mechanical arrangement which shall have a similar effect. The details
of course of the invention can be varied without departing from the principle of
the invention.

page_text: This invention can be applied not only to Bicycles and Safety Bicycles as shown,
but it can also be applied to Tricycles. It is applicable also to driving sewing
machines, foot lathes, and other descriptions of machines driven by manumotive
power. The principle of the invention being understood there will be no difficulty
in applying it to any of the machines mentioned, any engineer being able to adapt
the mechanical arrangements here shown without difficulty.
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 general arrangement of parts described as set forth in the above
Specification and accompanying drawings.
2. The use of any description of gearing, chains, steel bands etc. by which the
opposite pedal lever shall be raised or wound up by means of a spindle passing
through the centre of hub, and attached to the clutch box in manner described.
