PROVISIONAL SPECIFICATION left by the said Marcelin Cavalerie at the
Office of the Commissioners of Patents on the 27th May 1880.
MARCELIN CAVALERIE, Engineer, of Bordeaux, in France. "A NEW
IMPROVED APPARATUS FOR IMPARTING ROTARY MOTION TO MACHINERY."
OR
My novel Invention consists, 1°, in the application of the weight of two levers
as motive power; 2°, in the combination of these two levers to set a flywheel in
motion and give it great speed.
The said levers are at the same time of the second and of the third kind or
order; they are of the third order when they give rotation to the flywheel by their
weight; they are of the second order when the flywheel lifts them to the dead
point of the crank.
The lever of the third order is the best for speed, and that of the second order for
power. Thence it follows that the greater the speed given to the flywheel by the
levers of the third order the more easily the flywheel will lift their weight, and
this is the long sought solution of the problem of a prime mover or motive power
engine.
My motor machine is composed of a frame and two double-feet; these three
pieces bolted together support the whole of the driving mechanism.
The levers of the 2d and 3d order are of cast iron, and one of them should
weigh four times as much as the other. The two arms of each of these levers are
connected together by the aid of cross pieces or ties; thus constructed, these two
levers are jointed by one end of them to each double foot of the framing, and
by the other end the heaviest lever is jointed or linked to the centre of the lighter
lever. At the other end the lighter lever is jointed to the connecting of the
crank of the axle of the flywheel, the axle of which turns easily in two plumber-
blocks fixed to the frame of the machine by screws or bolts.
The whole being well constructed, according to the rules of mechanics, before
giving the motor machine any work to do it should be set in motion by hand until
Prine G21

page_text: all the detrimental frictions have become as slight as possible. Further, for a
profitable working it should not be connected with the driving pulley until the
flywheel has attained a speed of from three to four revolutions a second, and
the speed should be maintained between these two rates during the whole time of
working; this is an essential condition of the new system of motor to obtain
therefrom every possible advantage, that is to say, that there should be taken from
the motor machine only the excess of movement which it can dispose of while
continuing to work.
Motor-machines upon this new system may be made of any dimensions and of
any power, from that of a mouse to several hundred horse power, by making
levers of proportionate weight and the flywheel to correspond with the weight of
the levers.
The application of my novel system of motor machine is general and universal
as a prime-mover or motive power in the most various industries, for the marine,
for railways, and other roads or ways, for agriculture, in short, for all kinds of
machinery.

the said Marcelin Cavalerie in the Great Seal Patent Office on the 24th
November 1880.
MARCELIN CAVALERIE, Engineer, of Bordeaux, in France. "A NEW OR
IMPROVED APPARATUS FOR IMPARTING ROTARY MOTION TO MACHINERY."
My novel Invention consists,-
Firstly. In the application of the weight of two levers as motive power.
Secondly. In the combination of these two levers to set a fly-wheel in motion
and give it great speed.
The said levers are at the same time of the second and of the third kind or order;
they are of the third order when they give rotation to the flywheel by their weight;
they are of the second order when the flywheel lifts them to the dead point of the
crank.
The lever of the third order is the best for speed, and that of the second order for
power. Thence it follows that the greater the speed given to the flywheel by the
levers of the third order the more easily the flywheel will lift their weight, and
this is the long sought solution of the problem of a prime mover or motive power
engine.
The accompanying Sheet of Drawing shows, in elevation, a motor machine
embodying my Invention.
A, A, A, indicate a cast iron framing composed of a frame and two double feet;
these three pieces bolted together by four bolts support the whole of the driving
mechanism.
B, C, levers of the 2d and 3d order; these levers are of cast iron, and one of
them should weigh four times as much as the other. The two arins of each of
these levers are connected together by means of cross pieces or ties; thus
constructed, these two levers are jointed by one end, one of them to each double
foot of the framing, and by the other end the lever B, which is the heaviest, is
jointed or linked to the centre of the lever C by means of the piece D, which joins
the two levers together. At the other end the lever C is jointed to the connecting
rod E of the crank of the axle of the flywheel F. The two plumber blocks H, H, in
which the axle of the flywheel should turn easily, are fixed to the frame A by
screws or bolts.
The whole being well constructed, according to the rules of mechanics, before
giving the motor-machine any work to do it should be set in motion by hand until
all detrimental frictions have become as slight as possible. Further, for a profitable
working it should not be connected with the driving pulley (not shown on the
Drawing) until the flywheel has attained a speed of from three to four revolutions
a second, and the speed should be maintained between these two rates during the
whole time of working; this is an essential condition of this new system of motor
to obtain therefrom every possible advantage, that is to say, that there should be
taken from the motor-machine only the excess of movement or power which it
can dispose of while continuing to work.
Motor-machines or motive power engines upon this new system may be made of
any dimensions and of any power, from that of a mouse to several hundred horse
power, by making levers of proportionate weight and the fly wheel to correspond
with the weight of the levers, and I need scarcely observe that the several parts of
my motive power apparatus may be made of whatever material may be found most
suitable for its intended application.
The application of my novel system of motor-machine or apparatus for imparting
rotary motion to machinery is general and universal as a prime-mover of motive
power in the most varied industries and manufactures, for the marine, for railways,

page_text: and other roads and ways, for agriculture, in short, for all kinds of machinery, even
for children's toys and fancy or ornamental articles to be placed upon a table or a
mantel piece, like a clock.
In witness whereof, I, the said Marcelin Cavalerie, have hereunto set my hand
and seal, this Nineteenth day of November, in the year of our Lord One &
thousand eight hundred and eighty.
