I MARCELIN FRANÇOIS DOROTHÉ CAVALERIE of Paris, France, Mechanical
Engineer, 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 relates to motors which are adapted to work by centrifugal force and
by the force of gravity.
My said invention consists
1st. In the utilization as motive power, of the centrifugal force and the force of
gravity of heavy masses, in any number, of a special form adapted to cause a shaft
to turn.
2nd. In the utilization as a means for causing circular motion, of the continued
pressure of several helical or other springs applied to cause a shaft to turn.
3rd. In the combination and in the arrangement of the various parts composing the
new motor acting by centrifugal force and by force of gravity.
In the accompanying drawing
Figure 1 is a lateral view of the new motor, one of the plates C being removed to
show the heavy masses.
Figure 2 is a plan view of the same.
A is a shaft turning in the bronze bearings of the brackets B, B, fixed upon the
foundation plate D. To the shaft A are fixed by means of keys the two plates C. C.
these plates are turned and connected together by means of eight iron stays, four of
which are designated by the letter S, and the other four by the letter Z, the heavy
masses E of special form, are planed upon both faces, and are retained in the position
shown in the drawing by the stays Z upon which they exert a pressure equal to their
weight, and in their circular motion, exert a pressure corresponding to their centri-
fugal force, and thus the said heavy masses E cause the shaft A to turn.
In order to ensure the new motor turning as stated rapid rotary motion is imparted
to it to develop in the heavy masses E a quantity of centrifugal force sufficient to
destroy the equilibrium of their weight.
Means for maintaining the rapid rotary motion of the motor is provided by four
helical springs m which are always under tension, four cast iron pieces 9 are fixed to

page_text: one of the plates CC. Into each of these pieces g is screwed an iron rod n the
thinnest part of each rod carrying the powerful helical spring m.
These springs
exert a pressure upon the heavy masses E and upon iron washers e that are loosely
fitted upon the rods n. The said rods are turned by means of a special key to compress
the said springs as much as possible. Then their double pressures not equilibriated
cause the shaft A to turn.
The whole driving apparatus turns with a continually increasing velocity, because
its force is accelerated and accumulates in its entire mass.
To utilize the power of the new motor for any useful work, upon one of the ends of
the shaft A is fixed a pulley or gear wheel according to the work for which it is
intended. A brake will moreover be applied for regulating the motion thereof and
for stopping it at any time when such is required.
The driving mechanism is applicable as motive power to the most varying industries,
to marine, railway and like purposes, to agriculture, ballooning in short it is susceptible
of multiple and various applications.
It is to be understood that I reserve the right of varying the arrangement and
proportions of the improved apparatus according to the applications for which it can
be designed. Moreover I reserve the right of transforming it from a vertical motor
into a horizontal motor whenever this arrangement appears preferable.
Having now particularly described and ascertained the nature of my said inven-
tion, tandin what manner the same is to be performed, I declare that what I claim is.
First. The improved motor hereinbefore described and represented in the
accompanying drawing.
Second. The utilization as motive power of the centrifugal force and the force of
gravity of several heavy masses, whatever be the number thereof, these means acting
through the medium of the continuous pressure of several helical or other springs to
cause a shaft to turn as above described.
Third. The combination and the arrangement of the various parts composing the
new motor operating by centrifugal force and by force of gravity as described and
represented in the accompanying drawing.
