PROVISIONAL SPECIFICATION.
Improvements in and connected with the Driving Mechanism of
Velocipedes.
I, LEWIS CLEMENT of 2, Whitefriars Street, in the City of London Editor
of The Shooting Times, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to enable the riders of velocipedes to propel their
machines by means of both hands and feet or either of them.
Now according to this invention I hinge or pivot to the handle bar of the
machine on each side of the centre thereof a rod which is connected to a crank
secured to a shaft passing through the hub of the front or steering wheel or the
rods from the handle bar may be connected to the ends of suitable levers pivoted
to brackets forming part or attached to the front fork to which levers are pivoted
connecting rods engaging with the aforesaid cranks.
I prefer to attach the aforesaid rods to the handle bar by means of ball and
socket joints.
To allow the handle bar to oscillate in a vertical plane at right angles to the
steering wheel I form on or attach to the handle bar or the steering rod a
jaw which receives the steering rod or the handle bar a pin or bolt passing
through the said jaw serving as a centre on which the handle bar oscillates.
Dated this 19th day of September 1894.

Improvements in and connected with the Driving Mechanism of
Velocipedes.
I LEWIS CLEMENT of 2, Whitefriars Street in the City of London Editor of
The Shooting Times 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 object of this invention is to enable the riders of velocipedes to propel their
machines by means of both hands or feet or either of them.
Now according to this invention I hinge or pivot to the handle bar of the machine
ou each side of the centre thereof a rod which is connected to a crank secured to a
shaft passing through the hub of the front or steering wheel or the rods from the
handle bars may be connected to the ends of suitable levers pivoted to brackets
forming part or attached to the front fork to which levers are pivoted connecting
rods engaging with the aforesaid cranks.
I prefer to attach the aforesaid rods to the handle bar by means of ball and
socket joints.
To allow the handle bar to oscillate in a vertical plane at right angles to the
steering wheel I form or attach to the handle bar or the steering rod a jaw which

page_text: receives the steering rod or the handle bar a pin or bolt passing through the said
jaw serving as a centre on which the handle bar oscillates."
And in order that my said invention may be fully understood I will proceed
to explain the same with reference to the accompanying sheets of drawings in
which
Fig. 1 represents side view of a bicycle constructed according to this invention.
Fig. 2 is front view of same.
Fig. 3 represents side view of a modified form of bicycle constructed according
to this invention. Fig. 4 is front view of same. Fig. 5 is plan of same.
The same letters denote the same parts in all the figures.
a is a bicycle b the handle bar cd side rods connected at their upper ends by
means of ball and socket joints to the handle bar b and at their lower ends to
cranks ef secured to a shaft g passing through the hub of the front wheel.
Suitable gearing is interposed between the shaft g and the hub of the front wheel
to enable the front wheel to revolve twice or thrice during one revolution of the
cranks so as to reduce the number of vibrations of the handle bar per mile to as
few as possible. To enable the handle bar to vibrate in a vertical plane it is
pivoted at to a jaw k attached to the steering rod 7 or the jaw may be formed on
the handle bar b. By this arrangement of link work the rider is able to propel his
machine by alternately depressing each steering handle. To allow the machine to
be propelled by the feet alone without oscillating the handle bar the side rods may
be made of two tubes sliding one in the other and capable of being rigidly con-
nected together by means of a key, cotter, bolt or other device or the cranks may
be loose on the axles and connected thereto by means of pawls attached to the
cranks engaging with a ratchet wheel or wheels on the axle in such a manner that
oscillation of the handle bar propels the machine forwards. If the handle bar is
held stationary the steering wheel only rotates the axle revolving inside the
cranks.
The pivot of the handle bar may also be in the form of a bolt so that by tightening
the nut the handle bar is prevented from oscillating in the jaw and vice-versa.
In the modification shewn by Figs. 3. 4 & 5 the hub gear is dispensed with and
ordinary chain gear substituted. In this case the crank shaft g instead of passing
through the hub of the steering wheel passes through the front fork above the
steering wheel and is carried in suitable bearings secured to the fork. Also the
handle bar is made in two parts and boscillating on a bar or tube o passing
through the T head of the steering rod or tube l. When desired the handle bars
may be clamped in the usual steering position by the nut p after the side rods have
been disconnected.
Or according to a second modification the crank shaft 9 passes through the hub
of the front wheel and has secured to it a sprocket wheel which by means of a chain
communicates motion to a sprocket wheel secured to a counter shaft passing through
the front fork above the wheel.
The motion of the counter shaft being communicated to the front wheel by means
of a second sprocket wheel attached to the said shaft gearing by means of a chain
with a sprocket wheel attached to the hub of the front wheel.
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. In a velocipede the combination of a handle bar pivoted to the steering rod or
tube with a crank shaft passing through the hub of the steering wheel and side rods
connecting the cranks on the said shaft with the handle bar all substantially as
specified and for the purpose stated.
2. In a velocipede the combination of a speeding gear contained in or attached
to the hub of the steering wheel with a crank shaft passing through the hub of the
steering wheel and side rods connecting the cranks to a vibrating or oscillating
handle bar all substantially as described and for the purpose stated.

page_text: 3. As a modification of the mechanism hereinbefore described and claimed
substituting chain gearing for the hub speeding gear substantially as specified.
4. Driving mechanism for velocipedes constructed as hereinbefore described and
shewn and operating in the manner specified.
