I, WILLIAM CLARK, of 53, Chancery Lane, in the County of Middlesex,
Engineer and Patent Agent, do hereby declare the nature of the said 'Inven-
tion for "IMPROVEMENTS IN APPARATUS FOR TRANSMITTING AND MULTIPLYING
MOTIVE POWER," to be as follows:-
This Invention relates to an improved apparatus having for object' to
multiply a given power, at same time increasing the speed. This apparatus
may be applied to all kinds of machinery, for producing power, including
steam, gas, and compressed air engines, as also to hydraulic motors, wind or
horse mills, capstans, foot and other lathes, for the purpose above mentioned
of obtaining increased power and speed.
This Invention will be readily understood by referring to the accompanying
Drawing.
I have shown the apparatus as simplified as possible, in order to render its
principle easier understood, although I do not limit myself to any particular
form, which, together with the dimensions and arrangement of the parts, vary
according to the manner in which the apparatus is applied. A cursory
examination of the Drawing is sufficient to show that straps and gearing
wheels are dispensed with, the motion being produced by means of jointed

page_text: rods. In the Drawing the multiplier, properly so called, is shown as applied
to an apparatus receiving motion from a treadle or crank.
Fig. 1 is a front elevation of the apparatus furnished with the multiplier ;
and Fig. 2, an end view of the same. The letters serve for both Figures.
a, framing or uprights for carrying the various parts of the apparatus;
c, treadle working a fly wheel d in the ordinary manner, by means of a con-
necting rode and crank f; g, point of attachment of the first part of the
multiplier, which in the present instance is on an arm of the fly wheel d, for
imparting a to-and-fro motion to the first part of the multiplier, which may
be, according to circumstances, the end of a piston rod or other part having
a to-and-fro motion of which it is desired to increase the power and speed;
h, first portion of the multiplier, consisting of a rod jointed at the one end at
point g, and at the other to two rods i;j, constituting further portions of the
multiplier. The rod i is jointed at its upper end to a fixed point k, while
rodj is jointed to another rod l oscillating on a fixed point m; the latter rod
serves to regulate the motion of the end of rod j, although any other means.
may be employed for effecting the same result; as, for example, a fixed slide
may be used; n, rod, jointed the one end to point of rods j and l, and the
other to the part producing the power. In the Drawing this rod is jointed to
a crank p of a fly wheel q, which latter communicates motion to any kind of
apparatus. By this disposition of the parts for one turn of the lower fly
wheel & I obtain two turns of q, thus producing an augmentation of speed,
while the power is also increased. If required, several multipliers may be
applied to the same machine, and thus double, treble, or quadruple its speed
and initial force.
