Improvements in the Driving Gear of Bicycles, Tricycles, and other
Velocipedes, also applicable to other Vehicles.
ALLISON DAY of Grove Cottage, Rishworth, near Halifax in the County
of York, Labourer, do hereby declare the nature of this invention, to be as
follows:-
The object of my invention is to apply special mechanism or driving gear to
bicycles, tricycles, and other vehicles, so as to obtain greater driving power, from
a.minimum amount of energy.
. Upon the shaft of the driving wheel of bicycles, tricycles, and other vehicles,
I place a suitable flanged driving pulley or disc, connected by driving chain, band,
or belt, to a smaller drum or wheel upon a bracket attached to the cycle or vehicle
frame, upon the stud or shaft of this bracket is also a worm gearing with a worm
wheel, carried in suitable bearings upon the aforesaid machine frane, preferably
between the front and back wheels; upon one or each side of this worm wheel are
suitable, flanged pulleys or wheels connected by chain, straps or bands to wheels
upon each side of the hub of the back wheel.
By this means the flanged pulley upon the front wheel (being driven by cranks
or levers in any suitable manner) operates the worm which in turn operates the
worm wheel, connected by straps, bands or chain to the back wheel, so obtaining
great power for ascending inclines or other rough or uneven places.
Dated this Fourth day of November 1895.

I, ALLISON DAY of Grove Cottage, Rishworth near Halifax in the County of
York Labourer 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 apply special mechanisin or driving gear to
bicycles, tricycles and other vehicles, so as to obtain greater driving power, from a
minimum amount of energy.

page_text: I place a suitable flanged driving pulley, disc or chain-wheel B connected by driving-
chain, band or belt C to a larger drum or wheel D upon a bracket E attached to
the cycle or vehicle frame F, upon the stud or shaft G of this bracket are also
catch-wheels H and H¹ for operating the driving mechanism, these catch-wheels
are in turn operated from the pedals by means of catches J and connecting
rods or levers K, also these levers are so connected by chain L passing over chain-
wheel or pulley M, that as one pedal is depressed it raises the other into position
for the next movement of the rider.
By this means when a pedal is depressed the catch engages with the catch-wheel,
revolving same and operating the driving mechanism of the bicycle, tricycle or
other vehicle, at the same time raising the other pedal into position. By this
arrangement of driving mechanism, great motive power is obtained for ascending
inclines or other rough or uneven places.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
--
1. In bicycles, tricycles and other velocipedes the use and employment of
suitable catch-wheels H and H₁ operated by catches J and levers K connected
with the pedals J¹ for operating the driving mechanism substantially as shown and
described.
2. The general arrangement and construction of driving mechanism for bicycles
tricycles and other velocipedes, substantially as shown and described.
Dated this Fourth day of August 1896.
