page_text: LETTERS PATENT to Andre Marie Basset & Louis Nicholas Desiré
Lamoureux, Mechanical Engineers, of No. 10, Rue de la Fidélité, Paris,
for the Invention of "CERTAIN IMPROVEMENTS IN MOTIVE POWER."
PROVISIONAL SPECIFICATION left by the said Andre Marie Basset
and Louis Nicholas Desiré Lamoureux at the Office of the Com-
missioners of Patents, with their Petition, on the 7th January 1864.
We, ANDRE MARIE BASSET & LOUIS NICHOLAS DESIRÉ LAMOUREUX,
Mechanical Engineers, of No. 10, Rue de la Fidélité, Paris, do hereby
declare the nature of the said Invention for "CERTAIN IMPROVEMENTS IN
MOTIVE POWER," to be as follows, that is to say:-
The Invention consists in a peculiar construction of machinery for obtaining
motive power to work other machines, and is as follows:-Upon suitable
framing is mounted a wheel and axle, which is turned by hand and gives motion
to an excentric. The rod of this excentric is attached to the top of a peculiar
shaped lever, the bottom part of it being of a semicircular form and cogged for
gearing with a rack fixed below it, the said lever pivots on a sliding piece, which
it moves backwards & forwards in a proper opening in the framing provided for
the purpose. Attached to this slide is one end of a connecting rod, the other
end moving a crank fixed to a shaft or axle carrying a heavy fly wheel properly
supported, and on this shaft are fixed the pullies for transmitting the motion

One thousand eight hundred and sixty-four, in the twenty-seventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said Andre Marie Basset and Louis Nicholas Desiré Lamoureux, Her
special license that we, the said Andre Marie Basset and Louis Nicholas
Desiré Lamoureux, our executors, administrators, and assigns, or such
others as we, the said Andre Marie Basset and Louis Nicholas Desiré
Lamoureux, our executors, administrators, or assigns, should at any time
agree with, and no others, from time to time and all times thereafter
during the term 'therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "CERTAIN IMPROVE-
MENTS IN MOTIVE POWER," upon the condition (amongst others) that we, the said
Andre Marie Basset, and Louis Nicholas Desiré Lamouroux, our executors or
administrators, by an instrument in writing under our hands and seals,
or under the hand and seal of one of them, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that we, the said Andre Marie Basset and Louis
Nicholas Desiré Lamoureux, do hereby declare the nature of our said
Invention, and in what manner the same is to be performed, to be parti-
cularly described and ascertained in and by the following statement, reference
being had to the Drawing hereto annexed, and to the figures and letters
marked thereon, that is to say:-

page_text: Our Invention relates to the construction of a machine for increasing the
power of any kind of rotary engine by the application of a lever, the power of
which is increased according to its height, thus with a lever two feet long
we obtain one-horse power, one man being sufficient for working our machine.
If we double the height of the lever, not having more resistance to over-
come with a four feet lever than with one of two feet, double the power
of the lever of four feet is obtained in full, and which overcomes the increased
resistance.
But the nature of our improvements and the mode of working them will
be fully understood by reference to the figures and letters herein contained in
the accompanying Drawing, in which Figure 1 is a front view of our
improved machine ready to set in movement any kind of rotary engine.
In this Figure A represents the masonry work, on which are set the cast-
iron framings E and L, and rack B, which are imbedded in the masonry
work; B, is a rack having its cogs rounded off, and bearing the cog lever C,
(to which it serves as a fulcrum), and the cogs which correspond with those of
the rack B being also rounded off; D, cast-iron guide frame set on the masonry
work A, and serving to guide the lever C in its to-and-fro motion; E cast-
iron chair with bearings to support the shaft O; F, crank, forming an
excentric; G, crank arm, put in motion by the workman; H, coupling rod
connecting the lever C to the crank F; I, connecting rod, set on the centre of
the lever C, and jointed to the end of the crank arm J, forming an excentric,
and set in motion by the lever C by means of the connecting rod I. The
crank J puts in motion the pullies fixed on the main shaft K, and the fly
wheel M, placed on the said shaft. The main shaft K carries the fly
wheel M, and the motive pullies; L, bearing of the main shaft; M and N
are fly wheels; O shaft set on the chair E, and carrying the fly wheel N, and
crank arm G.
By the application of the principle herein-before described, a steam engine,
for instance, of two-horse power may have its motive power doubled for that
purpose, instead of coupling the piston rod of a steam engine with the connecting
rod J of our machine we attach it to the upper extremity of the lever C, by
leaving the connecting rod H, if we double the height of the lever by two feet
we will treble and quadruple the power progressively. By increasing the eleva-.
tion of the lever C, as the gearing is the same for one of small or large dimen.
sions, the expense of combustible is the same. The increase of power results.
from the point on the rack B, on which the lever C oscillates.
It is necessar
that the connecting rod I communicating the motion to the heavy fly wheel M,

page_text: be set on the centre of the lever C, whatever be the dimensions of the engine.
To put the machine to work, a man causes the crank arm G to turn and con-
sequently the shaft C, on which is set the crank F, which by its rotary
motion, and by means of the connecting rod H, communicates a to-and-fro
movement to the lever C, which movement is transmitted by the connecting
rod I, and crank J, (placed on the main shaft k,) to the fly wheel M, and to
the working pullies. The application of our machine requires but one
workman to superintend it, as by turning the crank arm G the machine is
by its own impetus put in motion.
.
The principle of the application of our machine to a windlass, and other
similar apparatus is the same as for a rotary engine, if a man can raise a
weight with a wheel of two feet diameter he will raise double the weight with
a wheel of four feet, and will treble and quadruple the force by increasing
the diameter of the wheel.
It is, however, necessary for the application of our Invention to capstans,
and other similar apparatus, that the length of the rack be equal to as many
times of the circumference as the wheel is to turn. Thus by unrolling and
having the fulcrum on the rack B, Figure 2, we obtain double the power of
that obtained by the ordinary windlass, because in this instance, instead of
employing, as herein-before stated for the rotary engine, balf of the wheel c,
we pull the extremity of the wheel by means of the cable J, which unrolls
from the drum M set in motion by the pinion G, which itself receives
movement from the crank arm F worked by the man. The wheel C in
receding from the rack B draws and winds up at the same time the cable R,
which passes over the pulley I, and rolls over the centre drum D, and thereby
raises the load suspended at the end of the cable K. The power of the
apparatus will be trebled and quadrupled according to the increase in the
length of the diameter of the cog wheel C.
A, Figure 2, is the sole plate on which is set the framing E; B is the rack
serving as fulcrum to the cog wheel C, which turns on the rack; D is the
central drum for the cable K; F crank arm worked by the man to put in
movement the pinion G; E framing to guide the cog wheel C; G pinion
setting the wheel M in movement; H, drum on which is unwound the cable J;
I, pulley on which passes the cable K winding up on the drum II, and which
draws along the wheel C, on the rack B; K, cable serving to raise the
load; L, main drum on which the cable J is wound, and which unwinds as
soon as it is wound up on the drum H; M, cog wheel causing the drum H
to turn.

page_text: And having now described the nature of our said Invention, and in what
manner the same is to be performed, we wish it to be understood that we do
not confine ourselves to the precise details herein laid down, but what we
claim is, the construction of a machine in which the power of the lever is
applied according to the length of its diameter to increase the force of
rotary engines, capstans, and other similar machines as herein-before described
and represented in the Figures of the accompanying Drawing.
In witness whereof, we, the said Andre Marie Basset, and Louis
Nicholas Desiré Lamoureux, have hereunto set our hands and seals,
this Thirteenth day of June, in the year of our Lord One thousand
eight hundred and sixty-four.
