We HORACE JAMES, Ironmonger and GEORGE ROBINSON Engineer, both of
103, Division Street, Sheffield in the County of York, do hereby declare the nature
of said Invention for "AN IMPROVED METHOD OF PROPELLING WHEELS BY HAND
OR FOOT POWER" to be as follows:-
It consists in communicating or transmitting the reciprocating motion obtained
by means of treadles or hand levers, in cycles, sewing machines, lathes and similar
machines, to the driving wheel by means of a flexible eord band or chain one end
of which is permanently attached to the frame or other fixed part of the machine
and which is passed round a pulley or roller upon or attached to the cranks of the
axle or to a pulley or roller attached to a fork or other bearing upon the crank and
round one or more pulleys or rollers attached to the frame or other fixed part of
the machine and the other end of which is firmly attached to the treadles or hand
levers of the machine.
By the use of this arrangement we double the power without any loss of speed.

We, HORACE JAMES, Ironmongers and GEORGE ROBINSON Engineer both of
103 Division St. Sheffield in the County of York, 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:-
It consists in communicating or transmitting the reciprocating motion obtained
by means of treadles or hand levers, in cycles, sewing machines, lathes, and similar
machines to the driving wheel in the following manner :-
To the frame or other fixed part of the machine we permanently attach one end
of a flexible cord, band, or chain, this is passed round a suitable pulley or roller,
upon the crank of the axle or upon a fork or other bearing, on the crank of the
axle, and round another suitable pulley or roller attached to the frame or other
fixed part of the machine, the other end is then attached to a pulley or cam upon a
pivot or shaft in suitable bearings, to this cam the treadle or hand lever is attached
or they may be attached to the shaft. These pulleys or cams, are grooved and
made of suitable size so that they take up a suitable length of the flexible cord;
band, or chain, round their circumference.
Where we employ two treadles we place each treadle and cam upon a seperate
shaft or pivot and gear them to work together, with an alternate motion so that
the flexibe cord, band, or chain is always beld at a proper tension and works with
a firm motion.
In order that the foregoing may be better understood, we send herewith a sheet
of Drawings in which a is the fixed end of the flexible band b, which is passed
round pulley c on the crank d and again round the fixed pulley e and then down
to cam or pulley f the circumference g of which takes up the requisite amount of
the flexible cord, band, or chain, to lift the crank to its proper height in the
revolution.
Having now particularly described an ascertained the nature of the said
Invention and in what manner the same is to be performed: we declare that what
we claim is :-
1. The combination of a flexible cord, band or chain, with two pulleys and a
cam or treadle pulley, substantially as described and shown herein before and in the
accompanying Drawing for the purpose set-forth.
