AN IMPROVED MACHINE FOR MECHANICALLY PRODUCING MOTIVE POWER
Year: 1884

page_text: I MARCELIN FRANÇOIS DOROTHÉ CAVALERIE, of Paris, in the Republic of
France, Mechanical Engineer do hereby declare the nature of my Invention for
"AN IMPROVED MACHINE FOR MECHANICALLY PRODUCING MOTIVE POWER"
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This Invention relates to an improved motor which I term a compound motor
and which may be employed for actuating all descriptions of machinery. An
illustration of this motor is shown by way of example in the accompanying
Drawings, in which
Figure 1 represents a side elevation, and
Figure 2 a plan.
The novelty of the Invention consists
First. In the employment as a lever, of four fly-wheels, capable of revolving
with great velocity on a swinging frame.
Second. In the whole combination of the parts constituting this motor-machine
for working with multiplo effect.
AA is a swinging frame of metal oscillating on the shaft B which is held by
two pedestals CO fixed on the foundation plate D. This swinging frame carries
four fly-wheels F F F F which are keyed to the two shafts X X revolving in the
bearings of the pedestals a a a a on the swinging frame A.
This frame is connected at each end by means of the connecting-rods G G to
the rocking levers H H which are connected by two rods J J with the two cranks
of the shafts XX which carry the four fly-wheels.
The two rocking levers H H are keyed on their shafts which oscillate in the
bearings of the pedestals I, I, I, I, fixed on the cast-iron foundation-plate D.
The fixed shaft B, which serves as a fulcrum for the swinging frame, carries a
drum or pulley K mounted on a bearing extending over its whole length and
which allows the said pulley to revolve freely on the fixed shaft B.
On the other hand, on one of the above named shafts X X two pulleys L L are
keyed, which pulleys serve to transmit, by means of a belt O, the rotary motion
of the fly-wheels to the drum or pulley K whence motion for the proposed useful
work is derived.

page_text: This motor which works with a multiple effect is caused to work freely by
acting with the hands upon one end of the swinging frame until the frictional
resistance has become, relatively so small that the machine will run without
further manipulation; it may then perform any required useful work.
Its power is in accordance with the velocity of the fly-wheels, for the more work
the motor is to perform the greater must be the velocity of the fly-wheels; this
velocity is regulated by the manual power applied to the machine as the initial
force.
It may be observed that, in order to apply this new motor to marine and railway
purposes and to the driving of carriages on roads, I replace the drum or pulley K
and the pulleys L L by toothed wheels, and the belts by chains.
It is obvious that this new description of motor may be employed in all the
various branches of industry, for marine and railway purposes, and in general for
vehicles driven on roads or rails, and for agriculture or for aerial navigation.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is:-
The improved motor working with multiple effect, substantially as above
described and shewn in the accompanying Drawings, which machine is essentially
characterized by the following features, viz. :-
First. The employment of a swinging frame provided with four fly-wheels
mounted in pairs on shafts situated on either side of the fulcrum of the swinging
frame and one of which carries pulleys or toothed wheels for driving a drum or
pulley mounted loosely on the shaft or fulcrum, and serving to receive the motion
which the machine is to transmit.
Second. The connection of the oscillating frame and the shafts carrying the fly-
wheels, by means of connecting rods coupled to the ends of rocking levers which
are pivotted on the foundation plate of the machine.
