Improvements in the Method of and Apparatus for the Propulsion
of Bicycles or Carriages.
I HENRY ALFred Poole, of 8 Cheetham Street, Rochdale, in the County of
Lancaster, Butcher, 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 :-
This invention relates to improvements, in the method of, and apparatus, or com-
bination, for the propulsion of bicycles, or carriages, to carry one, or more, persons.
The object, of my improvements, are to provide, a simple and effective method,
or combination, whereby, the propulsion of bicycles, or carriages, may be effected,
more easily, and in order, that my invention, may be more fully understood, I bave
caused, to be appended, seven sheets of drawings, marked with letters of reference,
indicating like parts, in the various figures.
Any of the parts contained in my said invention, may be made, of such demen-
tions, and material, such as steel, as are found most suitable, the working parts,
may be constructed to run, on ball or roller bearings.
Fig. 1, is a bicycle, shewing the apparatus, or combination, in position at (a),
working in conjunction, with a chain wheel at (y).
Fig. 2, is a side view of the apparatus, or combination, partly in section, shewing
the working parts, in their reative positions.
Fig. 3, is a section of bicycle frame, shewing the crank shaft X.
Fig. 4 and 5, shew the apparatus or combination in sections.
Fig. 6. shews a section, of bicycle frame, with the apparatus, or combination
attached, and in position.
In carrying out my said invention I use a wheel (a), Fig. 2, which is provided
with a number, of teeth, or spikes.
On its peripherie, these teeth, or spikes, are so formed that, they will gear into,
an endless chain, connected with the driving wheel at (y), Fig. 1.
On the inside, of the wheel (a), a number of cogs, or teeth are provided as
shewn in the drawing.
The cogs, or teeth gear, into another cog wheel, or wheels (c), Fig. 2 and 4, the
wheel, or wheels (c), gear into another cog wheel (b) Fig. 2 and 4, the wheel (b) is
made fast, so that it will stand still while the wheels, (a aud c) are allowed to
rotate.
In conjunction with the wheels, (a b c) I use a disc or round plate (e) Fig. 4
and 5, this disc, or 1ound plate, is provided, with a stud, or studs (k), (which, may
also be carried by the crank (d)).
This stud, or studs, carries the wheel, or wheels (c) Fig. 2 and 4, the disc, or
round plate is also provided, with two, ears (n), Fig. 4 5 and 6 these ears, are
provided, for the purpose of receiving, the crank (d), Fig. 24 and 6 the disc or
round plate, is further, provided, with a boss, (m) Fig. 4, this boss, is made to go
through the wheel (b), Fig. 2 and 4 and, acts as a bearing.
When the wheel (6) is placed on the boss (m) it gears into the wheel, or
wheels, (c) Fig. 2 and 4 the wheel (b) is provided with a boss, (u) this boss, is
made to fit into the wheel (a), Fig. 4 and 6 and acts as a bearing.
I also use a disc, or round plate (f), Fig. 4 5 and 6, this disc, or round plate, is
provided with one or more screws, as shewn in the drawing, these screws, are

page_text: provided for the purpose of fastening the disc, or round plate, (f) to the boss of
the cog wheel (4) Fig. 2 and 4,6 the disc or round plate (f) is further provided
with one or more pins or pegs or other suitable contrivance, these pins, or pegs, or
contrivance are provided for the purpose, of keeping the disc, or round plate (f)
fixed, or stationary, by reason of their passing through, the Hange or eyes, at (10)
Fig. 3 and 6.
Having, described the various parts, of this invention, they are fitted together,
in the following manner-The cog wheel (6) Fig. 4 is placed, on the boss (m) of
the disc or round plate, (e) Fig. 4 and gears into the cog wheel, or wheels (c) Fig. 2
and 4 then, the wheel (a) is placed on the boss u of the cog wheel (6) gearing into
the cog wheel, or wheel-, (c) by reason of the teeth, or cogs, on the inside, as shewn
in the drawings. Then the disc or round plate (f) is placed against, the wheel (a)
and fastened to the boss, of the wheel, (b) by one, or more, screws, as shewn, in
the drawings.
When the parts (fa bce) are placed together, as described, in the foregoing,
they are placed, on the crank shaft, X Fig. 3 at, either end, when the pins, or
pegs, or contrivance, on the disc, or round plate (f) Fig. 4 and 6 pass through, the
flange, or eyes, at (w), Fig. 3 and 6, then the crank (d) Fig. 24 and 6, is placed
on the crank shaft X, Fig. 3, in such a manuer, that, it will rest between the
ears (n) Fig. 4 5 and 6 the crank (d) is then keyed on the shaft X, or suitably
fastened.
Having, described the various parts, and how, they are applied, the movement, is
as follows.
When the crank (d), is caused, to rotate, it carries, the disc, or round plate, (e)
by reason of its resting between, the cars (n), the dise or round plate (e), carries,
the cog wheel, or wheels (c) by reason of the stud, or studs, (k) which, gearing into
the wheels (and a), cause the wheel (a), to rotate, at, an increased speed, by
reason, of the wheel (6) being fixed, or stationary.
N.B. also, adopt another movement, with the same, apparatus, or combination
by reversing, the priority of parts, viz., the disc, or 1ound plate, (e) carrying, the
wheel, or wheels, (c) is made fast, instead, of the wheel (b), by similar, means,
while wheels (a), and (b), are allowed, to 10tate, the wheel (a), is provided, with an
automatic stop, or stops, H Fig. 7, 8 near its peripherie, with a spring, H 2
Fig. 7 attached, in such a position, that it will keep it. in position, when not,
subjected to pressure. When it is pressed, it will sink down and allow the object
so pressing it to pass over it after which it will rise up again. The disc or round
plate (which cannes the wheel () Fig. 7) by reason of screws (H 4) is also
provided with an automatic stop or stops (H1) which act in the reverse direction,
when the clank (d) is caused to move in the direction indicated by arrow (1)
Fig. 7) it carries with it the wheel (a) by reason of its coming in contact with the
automatic stop (II) Fig. 7) thus propelling the bicycle or cariage.
If the rider wishes to mount an incline without dismounting he may do so by
turning the crank (d) in the direction indicated by arrow (2) Fig. 7 by so doing
the crank (d) comes in contact with the automatic stop H1 Fig. 7) which causes
the disc or round plate (f) to rotate carrying with it wheel (b) which gearing into
wheel or wheels (c) causes wheel (a) to rotate in the direction indicated by
arrow (1) by reason of the disc or round plate (E) carrying wheel or wheels (e) on
stud or studs (k) being made fast by the pins or pegs at W Fig. 8.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed i declare that what
I claim is
1st. The method of propelling bicycles or carriages, consisting in the use of
three or more wheels with cogs as shewn in the drawings, and utilizing the power
thereby created through an endless chain or other suitable connection working in
conjunction with the driving wheel or wheels at y Fig. 1 substantialy as set forth.
2nd. In the method of propelling bicycles or carriages specified in the preceding

page_text: claim a wheel (a) Fig. 2) working in conjunction with wheels (c) and (b) Fig. 2,

mor pins or pegs or other contrivance attached to the disc or round plate for the
purpose of securing the disc or round plate (f) to the flange or eyes at W Fig. 3
and 6 substantialy as set forth.
