Improvements in Velocipedes.
JAMES MOORE Ferrotype Plate Maker 18 Vauxhall Street Birmingham in the
County of Warwick do hereby declare the nature of this invention to be as
follows:-
As accompanying drawings. A Fig. 1, a wheel on hub of back wheel of
velocipede. B Fig. 1. an eliptic or beam shaped wheel toothed to gear with wheel A.
C Fig. 1 a groove in B. D Fig. 1 guide pin and carriage fixed on cycle frame H.
E Fig. 1 slide fixed on cycle frame H. Fig. 1 sliding wheel to turn and slide
in E. G Fig. 1 crank.
When crank is pressed down it causes B to rise, when crank is rised it causes B to
fall thus completing the circle the whole being governed by D E & F. Figs. 2. 3.
4. 5. 6. 7 being parts of Fig. 1 in section and flat.

JAMES MOORE Ferrotype Plate Manufacturer 258 Heneage Street late 18 Vauxhall
Street Birmingham in the County of Warwick 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 consists of a means of propelling velocipedes without the use of a
bottom bracket and chain as now in use, and can be produced less in weight, more
easily propelled more comfortable to sit upon, consequently more suitable for ladies
use. In describing my invention I will endeavour to be as concise and brief as
possiable.
I take Fig. 2 on the drawings accompanying my Provisional Specification A being
driving wheels, fixed on hub of back wheel of velocipede, made of two discs of
steel with holes for a number of pins as shown in Fig. 5, or in the place of pins, a
toothed wheel fixed between the two discs may be used, though I prefer the pins.
B Fig. 2, an elliptical or bean shaped wheel made of steel and toothed or geared to
any speed to work into and give motion to A. C Fig. 2 is a groove in which the
guide pin Fig. 6 travels, which guide pin is made of steel and supported from the
frame of velocipede H, the square hole at the end of B Fig. 2 is fixed on one end
of the sliding wheel F Fig. 4 the lever G Fig. 7 being fixed on the other end.
E Fig. 3 is the carriage for sliding wheel made of steel V shaped as shown in
section E Fig. 3 and supported from velocipede frame, this manner of supporting
carriage from frame of velocipede is one way, and so long as it is rigid it is sufficient,
but it may be pinned and brazed, or the clips for the frame may be dispensed with,
and the top V of carriage and part of the frame of velocipede may be forged in one
piece, I prefer it as drawing.

page_text: F Fig. 3 and Fig. 4 is the sliding wheel made of steel V shaped on face running
on ball bearings. This wheel slides in carriage E Fig. 3 backwards and forwards
bringing the teeth of the elliptical wheel B Fig. 2 into gear with A Fig. 2, caused by
the guiding pin in grove C Fig. 2, while the centre spindle of wheel takes a rocking
motion caused by lever Fig. 7 being moved up or down.
Having fully described the construction and working of Figs. 2. 3. 4. 5. 6. 7.
I now turn to Fig. 1 which is the complete invention, the working of which I describe
thus;-
The lever Fig. 7 is placed horizontally and the driving wheel on farthest side of
elliptical wheel from guiding pin. The lever G being pressed down B rises up, A is
then at the bottom of B and D is at the bottom of C. The lever being brought into
a horizontal position again, A is on the opposite side of B and D is on the opposite
side of groove C. The lever being raised B goes down, and A and D are at the top
of thire respective circuits, when bringing the lever back into its original position
the circle is described.
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.
An elliptical or bean shaped wheel geared to any speed,-governed by a guiding pin
and sliding wheel.
