HARRY HILTON, 31, Seafort Avenue, Sandymount, Dublin, Civil Engineer, do
hereby declare the nature of this invention to be as follows:-
The device consists of an arrangement of cog and pinion wheels connected
together by cranks.
The drawing shews two ways of applying the arrangement for propelling a
bicycle or other vehicle. In Fig. 1, the gear is shewn driven by rotary crank
motion. In Fig. 1, a crank 4, carrying a pedal 12, upon which the riders foot acts,
this pedal crank is connected by crank 5, to a cog wheel 3, this cog wheel 3 runs
in gear with the pinion wheel 2, this pinion wheel 2 is fixed fast upon the axle 7
upon which also is fixed fast the bicycle wheel, the various parts 4, 5, 3 & 2 being
thus constructed and connected together form the working parts of the gear by.
turning round the pedal crank 4 turns round cog wheel and cog wheel 3 turns
round pinion wheel 2. Cog wheel 3 being so many times greater in circumference
than the pinion wheel 2 causes same to revolve at a corresponding increased
velocity the pinion wheel 2 & bicycle wheel being fixed on same axle revolve
simultaneous. The cogs in pinion 2 and driving wheel may be made so as they
can be removed and replaced-or the cogs may be made of wood-or the pinion
wheel 3 and driving wheel 5, may be plain in place of cogs 4 & 6 in Fig. 1, their
faces on which they work with each other may be rough or may be covered with
leather rubber or other suitable material so that when they are brought together
and in gear they will work and revolve by friction. Pin 8 driving wheel 3 is carried
upon part of the bicycle frame. The device is in duplicate one on each side of the
bicycle wheel. A. brake is provided and numbered 16 in Fig. 1 this brake is
applied by means of rod No. 17 which runs from the 'brake block alongside of
bicycle frame up to the head of the bicycle & is applied by means of a lever
attached to the handle of the bicycle.
In Fig. 2 of drawing the motion is shewn as a up and down motion.
In Fig. 2, crank 2 carrying pedal 12 upon which the riders foot acts is con-
nected by crank 7 with cog driving wheel 5, this cog wheel 5 runs in gear with
pinion wheel 3, this pinion wheel 3 is fixed fast upon axle 9 upon which is also
fixed fast the bicycle wheel. The various parts being thus constructed and con-
nected viz. 2, 7, 5 & 3 together form the working parts of the gear by pressing
down crank 2 turns cog wheel 5 and cog wheel 5 turns round pinion wheel 3. Cog
wheel 5 being so many times greater in circumference than pinion wheel 3 causes
same to revolve at a corresponding increased velocity, the pinion wheel 3 and the
bicycle wheel being fixed to same axle revolve simultaneous. The cogs in pinion
wheel 3 and driving wheel 5 may be made so as they can be removed and replaced
or the cogs may be made of wood-or pinion wheel 3 and the driving wheel 5
may be made plain, in place of cogs 4 & 6 in Fig. 2 their faces on which they work
with each other may be rough or may be covered with leather rubber or other
suitable material so that when they are brought together and in gear they will

A guide is fixed on bicycle frame marked 16 in Figure 2 to steady the driving
crank 2 when working. The device is in duplicate one on each side of the
bicycle wheel. A brake is provided and numbered in Fig 217 this brake is
applied by means of rod No. 18 which runs from the brake block along side of 5
bicycle frame up to head of bicycle and is applied by means of a lever attached
to the handle of the bicycle.

HARRY HILTON, 31, Seafort Avenue, Sandymount, Co. Dublin, C.E., 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 invention has reference to a new or improved driving gear and brake
apparatus for cycles or other vehicle whereby the use of the endless chain is
dispensed with & economy and lightness effected without imparing the efficiency,
or rigidity of such machines.
I will describe the nature & operation of my said invention with the assistance
of the accompanying drawings.
Figs. 1, 2, 3, and 4 illustrate generally the application of my invention to a
bicycle frame specially designed for the purpose, each figure shewing a different
method whereby the driving gear may be actuated.
Fig. 4 is a detail view presently referred to-
A is an internally toothed spur wheel mounted on suitable bearings "B," fixed
in the frame of the machine and engaging a pinion, C, keyed to the spindle, D, of
the driving wheel.
The rotation of the wheel A imparts motion to the pinion, which in turn gives
motion to the driving wheel and hence to the machine.
The speed may, it is obvious be regulated according to the relative diameters of
the wheel & pinion.
This gear which is duplicated-one on each side of the machine-constitutes
the essential feature of my invention.
The gear may be actuated by means of a link arrangment as shown in Fig. 1.
Here the pedal crank 4 is fulcrumed at 11 and carries the link 5 the opposite end
of which is connected to the stud 8 on the face of the wheel 3.
The pedal crank is constructed as shown in Fig. 3.
It is provided with a dead eye at one end which slips on to the stud 14 and
a split eye at the other end which receives the pedal spindle 4 and a shoulder in
the centre on which the link 5 acts or the gear may be actuated direct by fixing
the pedal spindle in the face of the wheel A as shewn in Fig. 4, should the radius
of the wheel he not sufficient for the required throw of the pedal crank, a lug 4
(Fig. 4) may be attached to the face of the wheel in the extremity of which the
pedal spindle may be fixed.
Fig. 2, illustrates a second method whereby my improved gear may be actuated.
A lever 2 fulcrumed at 13 carries the pedal at its free end and is connected to
the wheel 5 by link 7.
The up and down movement of the lever 2 is guided by the quadrant 16.
The tech of the wheel A and pinion C may be made solid, or detachable so that
they may be readily replaced should occasion require.
Or the teeth may be dispensed with and the rolling contact surface roughed or
covered with rubber leather or other suitable material whereby the motion of the
one is imparted to the other by friction.
The second feature of my invention the method of applying the brake-is shewn
in all three figures & is duplicate.
The brake block in Fig. 1, No. 16, Fig. 2, No. 17, Fig. 4, No. 11 engages the
periphery of wheel A, is fulcrumed at 11 see Fig. 4 and is operated by means of
the rod 8 see Fig. 4 which is connected to a bell crank 9 Fig. 4 secured to the base
of the steering post, and is acted upon by a brake handle carried by the handle
bar of the machine in the ordinary way.
