Office of the Commissioners of Patents, with his Petition, on the
6th October 1874.-A communication from abroad by Gustave Jacob,
of No. 64, Faubourg St. Martin, Paris, France.
I, WILLIAM EDWARD GEDGE, of No. 11, Wellington Street, Strand, in
the County of Middlesex, Patent Agent, do hereby declare the nature of
the said Invention for "A NEW OR IMPROVED MACHINE FOR MULTIPLYING THE
FORCES OF MOTIVE-POWER ENGINES GENERALLY," a communication to me from
abroad by Gustave Jacob, of No. 64, Faubourg St. Martin, Paris, France,
to be as follows:-
The object of this Invention is to increase in a regular manner the
forces of any motive-power engine, and thereby to obtain a greater power
than that originally possessed by the engine.
The Invention springs from the result produced when a lever or a
screw is used to produce a greater effort than if such intermediary were
not used. Starting from this principle, if there be coupled to any motive-
power engine a machine which replaces the lever or the screw in the
man's hand, the forces of such motive-power engine will be multiplied in

page_text: one man are increased by use of lever
or screw. Thus if instead of producing a direct traction upon the
connecting rod of a fly wheel this traction were operated with the aid of
a screw, it will be understood that the power upon this fly wheel would
be increased.
It is evident that the speed would be lessened, but if by a combination
of toothed gearing suitably arranged a suitable speed is restored to the
fly wheel an active power will be developed in this machine which will
surpass that of the motor.
A machine for producing this result, and which forms the subject of this
Invention, is shown in elevation and in plan view on the accompanying
Sheet of Drawing.
The motive-power engine of which it is desired to increase the power
is in communication with this machine by two pulleys I, I', each of
which will receive in turn a rotary movement in opposite directions.
The rotation of one of these pulleys, say the pulley I, actuates a nut G¹,
gearing therewith by means of two catches J, J', one on the pulley, the
other on the nut.
The object of the rotary movement of the nut is to move the screw G
forward, and consequently give motion to the connecting rod F and
cranked shaft E. To bring back the connecting rod upon itself so that
it may perform a complete rotation the first pulley must leave the nut
in order that the pulley I which turns in the contrary direction may
give it a reverse motion.
The release of the nut from each of the pulleys after each stroke of the
connecting rod is effected by means of a fork M taking into a groove of
the nut. This fork is actuated by two rods K, receiving their motion
from two cams T, s, set on the horizontal shaft. These cams in causing
the balance beam P to move backward also move backward the springs
Q holding the rods K. The result is that in this movement the nut
shifts, quitting one or other of the pulleys, and produces alternately the
come and go motion of the connecting rod and the rotation of the cranked
shaft. This rotation is however very slow, and while giving great power
would give but little speed. It is therefore necessary to bring back to
a fixed speed a driving pully which actuates the tools or the machinery
to be set at work,

page_text: The speed is restored by means of a series of toothed gearing. Each
of the pulleys I, I', carries a toothed wheel X, which in connection by
means of the pinions y, y, v, v¹, v², v³, 21, with the main wheel U
actuates the two toothed wheels D, B. These toothed wheels drive the
shaft A, and consequently the pulley C¹ and the fly wheel C.
The effect of the movement of these toothed wheels and of the fly
which terminates them is to accumulate an active force which will
become more considerable in proportion to the increase of speed
A machine might be constructed upon this principle possessing but
one series of toothed gearing such as above described. By thus doing
away with the screw and all its mechanism the motive-power engine
will be in direct communication with a small pulley which will actuate
all the others. This Invention therefore consists in a machine serving to
accumulate and increase the original forces of a motive-power engine
of any kind, this machine being based upon the generic principle of "the
acquired power possessed by any body in motion," which law finds its
application in the setting in motion of the fly wheel and of the toothed
gearing which actuates it.
