COMPLETE SPECIFICATION (AMENDED).
Improvements in Cycles and Apparatus therefor for working the
same.
I, SAMUEL DAVIES, of 1, Devonshire Street, Marylebone, in the County of London,
Hotel-keeper, 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 :-
My invention relates to improvements in cycles and apparatus therefor for working
the same.
And in order that my invention may be thoroughly understood I now proceed to
describe the accompanying drawing thereof, reference being had to letters and figures
marked thereon.
Fig. 1, is a plan of the tricycle.
Fig. 2, is a section of the driving apparatus and pedal on line a, b. in Fig. 4.
Fig. 3, is a section of the hub with spring bolt and block and spindle on line y, y,
in Fig. 5.
Fig. 4, is a front elevation of the tricycle.
Fig. 5, is a section on line x, x, in Fig's. 3, and 4.
Fig. 6, is a side elevation of the tricycle.
Fig. 7, is a section on line z, z, in Fig. 6.
Fig. 8, is a plan of the top part of the bolt shewing the slot, drawn to an enlarged
scale.
In carrying my invention into practice the frame a¹ is provided with four
horizontal parallel supports 61 of any convenient section which are used as slides
or guides for the working parts and are fixed to cross bars c and c¹ at the back
and front. From the front cross bar c¹ is continued on each side a support d fixed
to the steering pillar e. On the back cross bar c is fixed one at each end vertically
connections for the axle bearings. In the centre of the back cross bar c is fixed
the seat pillar g. Near the top of the seat pillar g is fixed a stay the other end of
which is attached to the centre of the front cross bar this being part of the frame.
Near the top of the steering pillar e a tie rod is carried downwards and fixed
on the aforesaid stay of the frame. For a, bicycle the frame would have two
connections one on each side of the driving wheel for the seat pillar, otherwise the
frame would be similar to the tricycle.
For operating the tricycle or bicycle I employ two endless chains i running over
cog drivers and followers. The links of the chains i have raised points ; on each
side and each side link comes in contact with the other for the purpose of keeping
the top of the chain i straight.
The raised points j are used for driving the machine by means of pawls or catches k
that are pivoted in carriers / which travel on rollers m backwards and forwards on the
guides or slides 61 of the frame. Each chain passes over two toothed wheels n of
equal size, one toothed wheel is placed on the axle or hub of the driving wheel or

page_text: wheels, and the other is a guide to keep the chain the same distance apart and
revolves on a spindle fixed in the forepart of the frame.
There are two carriers one for each foot and each of the said carriers are composed
of two side plates connected together at the top by two spindles on which revolve
ball bearing rollers m. There are also under rollers m¹ so that the guides or slides of
the frame pass between the top and under rollers. The under rollers m¹ are separated
and on independent spindles. The side plates are vertical to receive the treadle pins p
which pass through them and on which the treadles q are pivoted. The lower ends
of the side plates are continued down below the chains and are secured together by
a bolt.
In a line with the lower part of the chains and on the side plates are pivoted the
lower pawl or catch 7. The top pawl or catch being pivoted in a line with the
top of the chain on the side plates. The pawls or catches having four sides are
shaped nearly square and the chains pass through them; two of the aforesaid sides
have holes near their centre and are pivoted thereto in these holes to the side plates
of the carriers. The part of the pawls or catches which engage the raised points of
the chains are V or wedge shaped. The other comes in contact with the opposite
sides of the chains thereby gripping the chains and carries the chains forward in
whatever direction the carriers travel. The top and bottom pawls or catches are
connected by links which throw each other in and out of gear. The lower pawl or
catch is reversed and thereby grips the chains on their return. strokes. A spring
buffers is attached to each of the side plates of the carriers and strikes the frame at
the end of each stroke and thus forces back the carriers.
The treadles q have a slot for regulating the size of the riders feet. They also have
slots or have holes at the sides where connected with the treadle pins for the purpose
.of getting the best position when applying power to drive the machines.
The driving wheel or wheels t are loose on the axle & but have a spring bolt or
catch v fitted to a lug on the hub u' as in Fig. 3. The hub u having a hole
shaped for the purpose of the end of the catch to pass through. A spring x¹ is
. placed against the lug wat back to keep it in position. The bolt or catch is provided
towards the front with a slot v¹ which works to and fro on a stud y so that when
passing the said stud y¹ that is fixed on the hub ¹ of the driving wheel or wheels it
presses against the spring x that the wheel or wheels can revolve free when going
down hill or turning corners. When driving the bolt or catch comes in contact with
the studs or blocks 2 on the axle and at the back and so force the wheel or wheels
round in the direction that the rider is going. If required the bolt vis disengaged
by hand to allow the wheel to over-run its axle.
A
The brake has two blades or jaws 1 crosswise with holes through where they cross
for the pivot pin to pass through, the pivot pin being fixed above the wheel to be
braked. The lower ends of the blades or jaws 1 are connected to small lever-arms
10 rivetted to the cross-piece-3 at the top ends by springs 2 to keep them apart.
cross piece 3 with slots the ends of which have pins passed through with pulleys
thereon. The top ends of the cross blades or jaws 1 pass through these slots and in
the centre of the cross piece 3 is fixed an upright arm 4 flat or half round with screw
thread cut thereon to receive a thumb screw 5 the top end of upright arm is bent
with a hole through to permit a wire rod 6 to pass down. The wire rod 6 passes
between the inside of the thumb screw and the flat of the upper arm and the lower end
of the wire rod is bent out below the thumb screw so that the moving of the thumb
screw up or down the arm will allow the handle bar 7 to be altered to the riders
requirements. The top of the wire rod 6 is attached to a flexible chain 8 and the
other end of chain is connected to the handle lever 9. The chain passes over a pulley
fixed in the slot of a bracket attached to the handle bar, so that by pulling up the
handle 9 of the brake lever the flexible chain passing over the pulley lifts the cross
piece 3 which closes the cross-blades or jaws 1 on to the rim or tires; the springs 12
reopening them when the lever handle 9 is released. The springs 2 are fixed to the
jaws 1. On the lower jaws or blades is fixed leather or other suitable material where
they grip the rim or tires of the wheel,

page_text: 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 cycles, the frame, substantially as above described in this specification and
illustrated in the drawings.

specification and illustrated in the drawings.
3. In cycles, the carriers and treadles, substantially as above described in this
specification and illustrated in the drawings.
4. In cycles, the method of the travelling backwards and forwards of the carrier on
the guides or slides for the purpose of driving the machine, substantially as above
described in this specification and illustrated in the drawings.
5. In cycles, the combination and arrangement of the brake, substantially as above
described in this specification and illustrated in the drawings.
6. In cycles, the combination of the lug w spring bolt or catch spring a stud y¹
