PROVISIONAL SPECIFICATION.
Improvements in Driving Gear for Cycles.
I, FREDERICK PETERS of 57, Kentish Town Road, London N.W., Fish
Curer, do hereby declare the nature of this invention to be as follows:-
In carrying into effect my improvements in driving gear for cycles I proceed in
or in about the following manner, that is to say, I reduce in diameter a portion of one
end of the bearing of the crank spindle (hereinafter referred to as "the bearing ")
and around this reduced part I place the chain wheel, not attached thereto, but
free to revolve thereon. To the chain wheel I attach a spur wheel or pinion
having its axis coincident with that of the crank spindle. To the extremity of the
reduced end of the bearing Fattach a disc of metal. Outside the disc 1 attach to
the crank spindle a spur wheel and outside that the crank itself. Through the
disc and free to revolve therein and situate at a greater or lesser distance from the.
axis of the crank spindle I pass a pin or short spindle, on one end of which is a
pinion or spur wheel which gears into that attached to the chain wheel and to the
other end of the pin or like I attach another spur wheel or pinion gearing into the
one attached to the crank spindle. The diameter of the spur wheels or pinions
will be arranged according to the speed required. The action is as follows:-
On rotating the crank, the spindle will revolve and the pinion thereon, will turn
that on one end of the pin passing through the disc, and will also revolve that on
the other end which will in its turn rotate the spur wheel or pinion attached to the
chain wheel and consequently cause the latter to revolve. I prefer to so arrange
the gearing that the pinions on the chain wheel side of the disc shall be sunk in a
recess in the face of the chain wheel and that the disc shall shut them in...
Friction wheels and pinions may be used instead of spur ones in carrying out my
invention.

Improvements in Driving Gear for Cycles.
I, FREDERICK PETERS of 57, Kentish Town Road, London, N.W., Fish Curer,
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 :-
In carrying into effect my improvements in driving gear for cycles I proceed in
or in about the following manner, and in this description I make reference to the
accompanying drawing, which is a cross section of a gear constructed in accordance
with my invention I reduce in diameter a portion a of one end of the bearing b of
the crank spindle c and around this reduced part I place the chain wheel d not
Price 8d1

page_text: attached thereto, but free to revolve thereon. To the chain wheel I attach a
spur wheel e which is free to revolve round the reduced part of b. Arising from b
and supported on the upright f, I provide the supplementary bearing g carrying
the supplementary spindle having at one end the pinion i and at the other end
the pinion j, the former gearing into a spur wheel k attached to the crank spindle 'c
and the latter () gearing into the spur wheel e already mentioned. I are the
cranks. The spur wheel e and chain wheel d may be joined together by screws m
or by any other means or the two may be cast in one piece. The black dots on
the drawing represent ball or other anti-friction bearings and such anti-friction
provisions may be employed in any part of the gear where found necessary or
desirable. There may be more than one support f, carrying more than one
bearing g and the support may if desired be a continuous disc-like one, but in
practice I prefer a single support as exemplified in the drawing. The relative
diameters of the wheels de and k and the pinions i and j, will of course be regulated
by the speed required to be attained. The action of the gear is as follows:-On
rotating the cranks 1, the spur wheel k and pinion i will be revolved and the latter
through the spindle h will revolve the second pinion ; which in turning will rotate
the spur wheel e to which the chain wheel d is attached, the direction of rotation
of e and d being consequently the same as that of the cranks 1. The speed of the
chain wheel d will obviously depend on the relative diameters of and i and
j and e..
I do not restrict myself to the precise configurations, relative proportions,
disposition of parts or other details described in the above specification or
exemplified in the accompanying drawing, as any or all of them may be considerably
varied without departing from the spirit of my invention.
Having now particularly described and ascertained the nature of my inven
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A driving gear for cycles and other vehicles, the said gearing consisting
essentially of a spur wheel attached to one end of the crank spindle and gearing
into a pinion at one end of a supplementary spindle revolving on an axis outside
that of the crank spindle the other end of the said supplementary spindle carrying
a pinion gearing into a spur wheel revolvable around the bearing of the crank
spindle, the last mentioned spur wheel being attached to the chain wheel so as to
revolve therewith. The whole substantially as described in the above specification
and exemplified in the accompanying drawing.
2. A driving gear for cycles and other vehicles the said gear being constructed
and operating substantially as described in the above specification and exemplified
in the accompanying drawing.
