PROVISIONAL SPECIFICATION.
Improvements in the Driving Mechanism of Cycles and the like.
I, CHARLES HELY MAWSON, 27, Windsor Terrace, Penarth, Coal Merchant,
and ALBERT LAKE KNAPMAN, 51, Plassey Street, Penarth, Blacksmith, do hereby
declare the nature of this invention to be as follows:-
-
Our invention has for its object to increase speed and power so arranged by an
up and down motion doing away with the revolving powers of the foot. It is
applicable for use with any cycle.
The apparatus consists of fulcrum-levers, cranks or excentrics or the like
The cranks or excentrics being used for carrying levers to proper positions, thereby
regulating the length of stroke as required.
The apparatus is attached to cycle or the like to framing by bolt, or made in
solid as preferred, the shaft of same working in fork, claw, or the like, fitted
into cranks, excentrics or the like, they acting as a carrier for lever bars, in
regulating the stroke short or long, as desired. The fulcrum-levers being in con-
nexion with main crank, gives power to drive same thereby working the said
cranks, excentrics or the like, these being connected also to end of lever by pin,
bolt, or the like. The cranks on main-shaft being short or long as you wish
gives speed or otherwise, it working in unionism with the power obtained from
the fulcrum-lever.
The two being coupled one with the other, so as to combine speed as well as
power.
The levers being connected with main shaft by rods or the equivalent thereof,
The cranks or excentrics or the like which is actuated in an automatic manner
therefrom, by chain-wheel, cog-wheel, crank or anything similar, the whole being
so put together as to be opperated from the end of the lever by the foot.

CHARLES HELY MAWSON, 27, Windsor Terrace, Penarth, Coal Merchant,
ALBERT LAKE KNAPMAN, 51, Plassey Street, Penarth, Blacksmith, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
-
It has for its object to increase speed and power, so arranged by an up and

page_text: down motion, doing away with the revolving powers of the foot, forming in its
travel an ellipse.
It consists of fulcrum levers cranks or eccentrics or the like,
the cranks or
eccentrics being used for carrying levers to proper
position, thereby regulating the length of stroke as required. It is
attached to cycles or the like to framing, by bolt or made in solid as preferred,
the shaft of same working in fork or claw or the like, fitted into crank or
eccentric or the like they acting as a carrier for lever-bars in regulating the
stroke short or long as desired, the fulcrum-levers being in connection with main-
crank gives power to drive same thereby working the said cranks eccentrics or the
like, these being connected to end of levers by pin holt, or the like.
The cranks on main-shaft being short or long as you wish gives speed or other-
wise, it working in union with the power obtained from the fulcrum levers the two
being coupled so as to combine speed as well as power.
The levers being connected with main-shaft by rods or the equivalent thereof.
The cranks eccentrics or the like which are actuated in an automatic manner
therefrom by chain-wheel. cog-wheel, crank or any thing similar.
The whole being so put together as to be operated from the end of the lever
by the foot.
Like wise the two small chain-wheels being connected and driven from main
shaft having the same number of teeth and being same in diameter work,
eccentrics or cranks uniformly every revolution with main crank thereby getting
the foot end of lever and end of main-crank in similar positions top and bottom.
A. Foundation-bridge, for main-crank shaft to work on, it is also a great
support for framing making it more rigid and doing away with vibration of
same.
B. Driving-wheel connected to sprocket-wheel similar to those on ordinary
cycles.
C. Main-cranks for driving chain-wheel. (B).
D. Connecting rods used for coupling main-crank to lever bars.
E. Fulcrum lever bars give power to drive crank (C). When joined with,
(crank (H) or eccentric they form its fulcrum.
F. Small chain-wheel, fastened to crank-shaft, drives small wheel ((+) by
chain.
G. Small chain-wheel used for revolving cranks (H) or (eccentrics).
H. Cranks or eccentrics, used for regulating stroke at foot end of lever.
I. Chain for coupling wheel (F) to wheel (G).
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
1st. That chain-wheel crank or the like fixed on shaft, driven from main crank
driving wheel, crank, or the like, at bottom, fixed on shaft, the said shaft carrying
eccentrics, or cranks for regulating stroke of lever-bars, the lever-bars being
connected to main-crank by rods or the like these working in union form our
invention.
(2). In gaining power by fulcrum enabling to drive with less pressure, also
smoother action for the foot on account of end of levers, at other end riding on
eccentric sheaves or cranks like-wise by doing same speed with less travel of foot.
(3). In gaining speed, by cranks on main-shaft being shorter, they go through
less space with the same number of revolutions the increased pressure which is
required to drive main-cranks is overcome by the leverage of the fulcrum.
