PROVISIONAL SPECIFICATION.
Improvements in Driving Mechanism for Velocipedes.
I, RICHARD PRICE, of 114 Long Street Sparkbrook, Birmingham in the
County of Warwick Inspector of Police do hereby declare the nature of this
invention to be as follows:-
:-
The object of my invention is to produce an improved driving mechanism for
velocipedes, and I carry this into effect by attaching a bevil wheel to each side of
the driving wheel of the velocipede. A similar bevil wheel is attached to each
pedal, these wheels being larger or smaller than those first mentioned, according to
the requirements of the rider. A short shaft, with a bevil wheel fixed to each end,
transmits the motion of the pedal wheels to those upon the spindle of the driving
wheel.

COMPLETE SPECIFICATION.
Improvements in Driving Mechanism for Velocipedes.
I, RICHARD PRICE, of 114 Long Street, Sparkbrook Birmingham in the
County of Warwick, Inspector of Police, 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 object of my invention is to produce an improved driving mechanism for
velocipedes, by means of which the power is directly transmitted from the pedals
to the driving axle without the intervention of chain or other linked gearing, and
the speed is materially increased relatively to other methods of and means for,
gearing up or connecting the driving wheel with the pedals as hitherto adopted.
In order that my invention may be the better understood I have appended
the accompanying sheets of drawings, in which
Figure 1, Sheet 1 shews a safety bicycle fitted with said mechanism, and
Figure 2, Sheet 2 shews one section of the mechanism according to my invention
with the housing strap and footstep for connection with the axle of the driving
wheel, and
Figure 3 shews the same section in situ, the strap and footstep upon the axle of
the pedal spindle being similar to that upon the other end as before referred to in
connection with Figure 2.
In carrying my invention into effect, and applying the same to an ordinary safety
bicycle I employ a shaft or spindle A suitably supported in journals or sockets B
and F, so that it may freely revolve. A bevil pinion G is attached to one end of
said shaft or spindle A, which gears with a bevil wheel D upon the pedal spindle.
The power applied to the pedals is thus transmitted from said pedal spindle D to
the driving spindle D' by means of a second bevil pinion G', upon the opposite end
of the shaft or spindle A, and a bevil wheel H upon the driving wheel spindle D',
gearing therewith. The footstep bearings F and F are supported by straps and
studs C and C', connecting said bearings to yokes which may form part of, or be
attached to the frame of the machine so that the two ends of the spindle A are
supported directly by the spindles D and D¹ respectively, and any oscillatory or
vibratory movement is thereby compensated. The relative sizes of the pinions G G¹
and wheels H and H are arranged to suit the requirements of the rider. The
CD

page_text: arrangement of pinions, wheels and shaft may be adapted to each side of the
machine, the bearings being placed at an angle upon the yokes so as to clear
the driving wheel, as shewn by the plan, Figure 3, Sheet 2.
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;
First. In a safety bicycle the construction and use of bevil wheels H attached to
the driving wheel axle, and bevil wheels H' attached to the pedal spindle in
combination with shafts or spindles A carrying pinions G and G₁, substantially as
and for the purposes herein specified, and as shewn by the appended drawings.
Second. In a safety bicycle the method of and means for transmitting power and
motion from the pedal spindle to the spindle of the driving wheel, substantially as
herein described with reference to the drawings hereunto appended.
