Improvements in and relating to Bicycles, Tricycles, and other like
Vehicles.
I, SAMUEL DAVIES, of 1 Devonshire Street, Portland Place, in the County
of London, Hotel Keeper, do hereby declare the nature of this invention to be as
follows:-
:-
My invention relates to improvements in bicycles, tricycles, and other like
vehicles, which consists of mechanism for driving direct from the treadles unto
the rim of the driving wheels and other analogous fittings.
The frame for the bicycle is constructed with two arms or supports carried
and continued forward from the centre of the back or driving wheel and
terminates in a curved head which rests on a swell in the top of the front wheel
fork. In the centre of the swell a hole is provided through which passes the
upright of the handle bar. Below the curved head is a cross piece of any suitable
shape fixed on the arms of the frame. A fork is fixed on the frame for the seat
bar to pass through the top; the lower ends of this said fork are continued
below the frame to carry the treadle spindle. A arm or bracket on each side
of the fork is carried forward from the base of the treadle spindle bearers, to
the frame, to support the spindle of the cog wheel which revolves or operates on
the driving wheel of the bicycle. The front or guiding wheel fork has a flat
surface at the top, and from this is carried up a bracket bent back and rests on the
cross piece or quadrant at the head of the frame. To the end of the bracket a
support is fixed for the upright of the handle bar to seat itself in the centre of the
flat surface of the swell. The lower end of the handle bar passes through a hole
and is fixed thereto for the purpose of steering.
The tricycle frame is attached to an axle which carry the two leading or guide
wheels, and in the centre of the said axle between the two wheels is placed the
frame of the driving wheel and mechanism in a similar way to that described for
the steering of the bicycle.
The driving mechanism consists of a driving wheel fixed on the spindle of the
treadles, the said wheel having cog teeth which gear into a small cog wheel
follower fixed on the spindle which carries a large cog wheel to operate on pins in
the circumference at the side of the rim of the driving wheel of the tricycle.
The aforesaid large cog wheel has teeth cut in on the outer edge which gear
into stud pins or projections fixed on the rim at the side of the driving wheel of
the tricycle, bicycle, or any like vehicle.
For fixing nuts, hubs or cones, or collars, I provide a stud fixed in the spindle or
axle with a hole or opening and in this hole or opening I mount a jointed spring
pall or ratchet which falls in between teeth on the nuts cones or collars. The
object being that when any such nut or collar is screwed up the pall or ratchet is
forced down into its seating between the teeth, so that the nut or collar will not
become loose through vibration.
It will be understood that the foregoing is given by way of illustration, and that
the shapes, materials and proportions of the various parts may be varied in many
ways within the
scope of my invention.
Dated this 11th day of December 1890.

Improvements in and relating to Bicycles, Tricycles, and other like
Vehicles.
I, SAMUEL DAVIES, of 1 Devonshire Street, Portland Place, 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 bicycles, tricycles, and other like
vehicles, which consists of mechanism for driving direct from the treadles unto the
rim of the driving wheels and other analogous fittings.
I attain these objects by the mechanism illustrated in the accompanying drawing,
in which
Figure 1 is a side elevation of a tricycle with one of the front wheels removed;
Fig. 2, is a plan of the frame and driving mechanism with the treadles
removed.
Fig. 3, is a section of the collar and swell with the handle bar broken off, drawn
to an enlarged scale.
Similar letters refer to similar parts throughout the views.
The tricycle frame is attached to an axle which carries the two leading or
guide wheels, and in the centre of the said axle between the two wheels
placed
a swell D of the frame of the driving wheel m and mechanism for the driving of
the tricycle.
The driving mechanism consists of a driving wheel G fixed on the spindle of
the treadles, the said wheel having cog teeth which gear into a small cog wheel
follower H fixed on the spindle I which carries a large cog wheel J to operate
on pins K in the circumference at the side of the rim of the driving wheel m
of the tricycle. The aforesaid large cog wheel J has teeth cut on the outer edge
which gear into stud pins K or projections fixed on the rim at the side of the
driving wheelm of the tricycle as in Figs. 1, and 2. The front or guiding
wheels axle has a flat surface at the top and from the rear is carried up a
bracket E bent back and rests on the quadrant n between the stop pins o, o,
in the front part of the frame l.
For fixing the collar C as in Fig. 1, I provide a stud fixed in the handle bar
(spindle or axle), with a hole or opening and in this hole or opening I mount a
jointed click B which falls in between teeth on the nut C or collar. The object
being that when any such nut or collar C is screwed up the click is forced down
into its seating between the teeth so that the nut or collar C will not become
loose through vibration, as described in Figs. 1, and 3, above the swell D of the
frame l.
The lower end of the handle bar passes through a hole in the swell D of the
frame and a hole in the swell of the front axle and keyed thereto.
For a bicycle I adopt the same driving mechanism; but the head of the frame /
I curve upwards in order that the swell D shall rest on the top of the front fork,
similar to an ordinary bicycle. The lower end of the handle bar passes through
the swell and the fork and is fixed thereto for the purpose of steering.
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 tricycle, the combination of the frame carrying the treadle spindle and
the lower cog wheel spindle with cog driver G follower H and large cog J to
operate on the pins K of the driving wheel m, substantially as herein described and
according to the accompanying drawing.
2. In a bicycle, the combination of the frame carrying the treadle spindle and

page_text: the lower cog wheel spindle with cog driver, follower and large cog to operate on
the pins of the driving wheel, substantially as described.
3. In a tricycle, the combination of the swell and quadrant with set pins at the
head of the frame, and the swell on the axle with bracket and the handle bar
5 for fixing the frame and axle together, substantially as herein described and
according to the accompanying drawing.
4. In a tricycle, the combination of the coilar with teeth cut and a click to
fall in between the teeth when the collar is screwed up, substantially as described.
Dated this 7th day of August 1891.
