I GEORGE HENRY TROW of 3 Perrymans Farm Road, Barking Side, in the
County of Essex, Carpenter, do hereby declare the nature of this invention to
be as follows:-
This invention relates to improved motive power machinery on the lever
principal according to one way of carrying out this invention I take a lever of any
desired length according to the power required to be obtained such lever having
its fulcrum at say one foot more or less from one end thereof and to that end of
the lever nearest to the fulcrum I conuect a chain passing under a pulley suitably
mounted below the said lever the said chain then passes round another pulley
suitably fixed above said lever on to a shaft the end of said chain being fixed to
this last named pulley so that when the chain is pulled by the action of the
aforesaid lever it will turn the shaft one revolution and I also key on to the shaft
another pulley of larger diameter than the former one on to the periphery of this
last named pulley I connect another chain the end of which is connected to that
end of another lever furthest from its fulcrum the other end of this lever being
suitably connected to one crank of the driving shaft so that upon the last named
lever being pulled it shall turn such driving shaft.
I make the above in duplicate so as to actutate the other crank and thus produce
a complete motive power machine.

COMPLETE SPECIFICATION.
Improved Motive Power Machinery Worked by Lever and
Weight Power.
I GEORGE HENRY TROW of 3 Perrymans Farm Road, Barking Side, in the
County of Essex, Carpenter, 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 :-
This invention relates to improved motive power machinery on the lever
principle.
And in order that my said invention may be understood I describe the same
with reference to the accompanying sheet of drawings in which :-
Fig. 1. shews side elevation of the machinery with the interior parts dotted.
Fig. 2. shews end elevation of same.
Fig. 3. top plan.
Similar letters denote the same parts in all the views:-
a shews hand lever by which the machinery is worked. The fulcrum of this lever
is at 6 and it is pivotted at its end to link c which latter is connected to a three
throw crank shaft d said cranks being set at right angles to one another, e is a
wheel keyed on shaft f. gg are pulley's keyed on the same shaft hh are ratchet
wheels one of which is keyed on the shaft f. into which the clicks i i engage,

pulleys m m' nn are speed wheels running loose on spindles o o. pp are speed
wheels keyed on spindles y running in brackets r. s is another pulley keyed on
spindle running in brackets u, vrare levers whose fulcrums are at w w these
levers are furnished with weights xx, y y are forked levers carrying clicks z. z.
engaging in ratchet wheels 1, 1, 2 is a band looped at one end on to one of the
cranks on crank shaft d, and passing over pulleys g, g, and under pulley 8, the
other end being looped on the opposite crank on shaft d. 3. 3. are bands looped
at one of their ends on to cranks 4 the other ends being fastened to the smaller
diameters of speed wheels p. p. 5 is an endless band passing round pulleys 6 and 7,
8. 8. are cords having one of their ends fixed to pulleys k, k, and their other ends
to levers y. y.
99 are two cords having one of their ends passing round and fixed
to pulleys or speed wheels m m and their other ends to the outer diameters of speed
wheels n. n.
10 10 are cords one end of which passes round and is fixed to the
smaller diameters of speed wheels n. n the other ends being fixed to the ends of
levers v.
11 are cords one of their ends being fixed to the other ends of levers v.
and the opposite ends of said cords are passed round and fixed to the larger
diameters of speed wheels p. p. 12, 12. are guides for cords 11, 11. 13 is a chain
drum, on lifting shaft 14.
The action of the machinery described above is as follows:-
:-
Upon actuating the lever a. it turns the crank shaft d. thereby pulling down one
end of the band 2. and allowing the other end to go up thus revolving the wheels g, g
communicating its motion to the pulley 7. The motion is then communicated to
the cranks 4. 4. from thence to the small diameter of speed wheels p. p. from
the large diameters of which an oscilating motion is communicated to the weighted
levers v. v.
From the other ends of the weighted levers v. v. an oscilating motion is imparted
to the speed wheels n n and thence to the pulleys m m' by means of the cords 9, 9,
and 10, 10 which in turn also oscillates the wheels kk and levers y y by means of
the bands 8. 8.
These levers working on to ratchets 1, 1, by means of clicks z. z. cause the chain
drum 13 to rotate, in order to lift heavy weights, with a small amount of
power exerted on the lever a; by reason of the extra leverage obtained
owing to the varying diameters of the pulleys and wheels, and the different lengths
of levers.
It is obvious that instead of employing hand power to actuate this machine any
other power may be used, by connecting a strap on to wheel e.
I do not intend to limit myself to the number of wheels and levers described and
shewn as these may be varied to suit requirements.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
Motive power machinery constructed substantially as described and represented
on the accompanying sheet of drawings.
