JAMES JESSE CARPENTER Cook & Confectioner 57 High Street Stoke Newington
Middlesex do hereby declare the nature of this invention to be as follows
The long end of a lever or levers is or are attached to the motive power & the short
end of the lever or levers by a rod to the crank or wheel to be turned for giving
motion to the machine.
The levers can be used horizontally or perpendicularly and the force to be used can
be steam or other power.

JAMES JESSE CARPENTER, Cook and Confectioner, 157 High Street, Stoke
Newington Middlesex 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:—
My invention consists in the employment of a lever or levers, at or near the end or
ends of the long arm or arms of which I apply motive power, and the other arm or
arms attach to a crank or cranks for doing work. The levers can be set horizontally,
or vertically, or at any angle with the vertical. In preference I use four levers or sets
of fours with the cranks of each one of the four fixed to the axle at right angles to
the next one.
To show how my invention is carried out I furnish drawings in which similar letters
represent corresponding parts throughout. I do not however limit myself to the
method here shown of applying the motive power but use any convenient method of
moving the long arms of the levers.
Fig. 1 is a longitudinal section of one lever showing its fulcrum and attachment to
the crank.
Fig. 2 is a front view of the machine with four levers attached to their respective
cranks on a common axle.
Fig. 3 is a back view of the machine showing an arrangement for raising the long
arms of the levers.
Fig. 4 is a longitudinal section of a cross beam showing the supports of the
levers.
Fig. 5 is a cross section of same.
Fig. 6 is a front side view of the framework of the machine.
The framework consists of oblique side beams A resting on and fitted into a founda-
tion B. Longitudinal beams C are employed to strengthen the frame and to furnish
supports for cross beams D, on one of which are the supports or fulcra E of the
levers F. Additional supports G are provided for the framework wherover desirable.
This particular construction of the framework is not essential to the carrying out my
invention. All that is necessary is to provide a firm support for the levers and other
moving part of the machinery. Each lever F is pivoted on an axle W resting in a
groove X in the cross beam D, the axle W passing through the said lever F. The
short arm of the lever F is attached by means of a connecting rod H to the crank J.
The connecting rod H is immediately attached to the fork U which is firmly secured
to the short arm of the lever F by bolts or screws Y. To the axle K is fitted a wheel L
which can communicate motion directly or by a band or chain or suitable gearing to a
machine for doing work. The end of the long arm of each of the levers F moves between

page_text: two bands or chains M revolving round two pulleys N and O. The pulleys N are fitted
on and turn with an axle P which is turned by the application of the motive force to
the wheel fitted on the end of the said axle P. The pulleys O are also attached to
and move with an axle R. Studs or buttons S can be fixed on the pulleys to ensure
the revolution of the bands M. A transverse bar T is fixed to and revolves with
each pair of bands, one bar to each lever. With the levers arranged as shown in the
drawings, as each bar T comes under its lever F at the pulley N it moves the lever F
towards the pulley O. As the bar T continues to revolve it disengages itself from
the lever F, which then moves back again by its own weight and the movement of the
other levers. The transverse bars T are so placed that the levers Fare moved
at regular intervals one after the other. The elevation of the long arm of the lever F
depresses the crank J attached to its short arm, and so the regular movement of the
long arms causes a regular revolution of the axle K.
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:
1. The application of driving power to the long arm or arins of a lever or levers,
the sort arm or arms of which are connected to a crank axle for accomplishing
work.
2. A contrivance consisting of one or more such levers arranged as described in
claim 1 for accomplishing work.
3. The method of moving the long arms of the levers substantially as described
in the foregoing specification in combination with the contrivance described in
claim 2.
