IMPROVED MOTOR APPARATUS FOR FACILITATING THE UTILIZATION OF MANUAL POWER
Year: 1885

page_text: I, MARCELIN FRANÇOIS DOROTHE CAVALERIE, of Paris, in the Republic of France,
Engineer do hereby declare the nature of my invention for "IMPROVED MOTOR
APPARATUS FOR FACILITATING THE UTILIZATION OF MANUAL 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 applicable to various kinds of work.
The novelty of the present invention consists :-
1st In the utilization of two fly-wheels rotating at a great velocity upon an
oscillating frame; 2nd, In the combination of the various parts composing the
motor; and 3rd, In the application of a hand lever for setting the motor in motion,
and for increasing its useful effect.
In the accompanying drawing
Figure 1 shows a side view of a motor constructed according to this invention
and
Figure 2 a plan.
A A represent a frame of metal oscillating upon the shaft B and supported by
two brackets C C fixed upon the bed-plate D. This oscillating frame carries two
fly-wheels E, fixed by means of keys upon the shaft Z revolving in the bearings of
the brackets a a on the oscillating frame.
The said frame is united through the medium of a connecting rod G to the
rocking lever H, which is itself connected by means of the rod J to a crank on the
shaft Z carrying the two fly-wheels.
The rocking lever H is keyed upon its shaft supported in the bearings of
the brackets II fixed upon the bed-plate D.
The fixed shaft B serves as the point of articulation of the oscillating frame.
This shaft carries a drum pulley K mounted upon a sleeve which extends over its
entire length and enables the pulley to turn freely upon the fixed shaft B.
The shaft Z carries two pulleys L L which serve for the transmission of the
motion. These two pulleys drive, by means of belts O O, two other pulleys L' L¹
mounted upon the same sleeve as the drum K. In this manner the two pulleys LL
transmit the rotary motion of the fly-wheels to the drum pulley K, from which the
motion is transmitted for effecting useful work.

page_text: A lever of the second order and movable upon a shaft X is articulated to a
connecting rod N. This rod N serves to connect the lever Q to the crank pin g of
the fly wheel E.
In the operation of the motor the lever can be directly acted upon from time
to time proportionately to the work which is to be done without stopping the
motion of the apparatus.
This improved motor apparatus provides a means for utilizing manual power
for various industries, for marine, railway and other purposes; for agriculture and
ballooning, and it is capable of various other applications.
It is essential that the improved machine motor should be well constructed in
order that the movements may be quite smooth and without counter pressure of
any kind. Moreover, for good operation it is essential to place the point of
articulation of the connecting rod G in the same plane as the two shafts B and Z.
It is obvious that I may modify the arrangements and proportions of the
apparatus described according to the purpose for which it is to be employed.
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
First. The improved motor apparatus hereinbefore described and illustrated in
the accompanying drawing.
Second. The arrangement of an oscillating frame A provided with two fly-
wheels E mounted upon a shaft Z, which shaft also carries two pulleys L L driving
the drum K from which the motion of the motor apparatus is transmitted, as
described and illustrated.
Third. The combination of the oscillating frame A. and the shaft Z, carrying the
fly-wheels E, the said frame and shaft being connected by means of the rods G
and J connected to the extremities of a rocking lever H articulated upon the bed
plate D of the apparatus, as described and illustrated.
