PROVISIONAL SPECIFICATION.
Improved Means for Transmitting Manual or other Motive Power
for Driving Machinery.
I FRANK WILLIS CLARK of Mount Desert, in the County of Hancock and
State of Maine, United States of America, Stone Cutter, do hereby declare the
nature of this invention to be as follows:-
The object of my invention is to provide a motor of which the construction is
very simple, which is very effective in operation, and arranged to uniformly
transmit power to machines to be driven.
The invention consists of a shaft connected by a joint with a second shaft
carrying a weighted arm, and mounted to swing.
The frame of the motor carries a bracket, in which is journaled a vertical shaft
geared by bevel gear with a shaft journaled in suitable bearings on the main frame,
and carrying for example a hoisting drum or other machinery to be actuated by the
motor. The upper end of the shaft terminates in a fork which supports a plate.
having at its centre an aperture to receive the squared end of a second or upper
vertical shaft adapted to be swung sidewise out of alignment with the lower shaft,
the reduced or square end being sufficiently loose in the aperture to permit of such
movement.
The upper shaft is provided with a collar which is pressed on, on opposite sides,
by the free ends of springs attached to the main frame which tend to maintain the
shaft vertically and its extreme upper end is engaged by a lever fulcrumed on the
main frame and adapted to be actuated by hand or by suitable machinery such as
the crank arm of an engine, to impart a swinging motion to the said lever. From
the upper shaft extends, at or nearly at right angles, an arm carrying a weight at
its outer end.
The operation is as follows--
When the lever is swung, the weighted arm in trying to move to its lower
position according to the inclination of the shaft to which it is attached causes the
latter to turn until the arm continuously swings round and a rotary movement is
given both to the shaft to which it is attached and to the shaft below, which latter,
by the gear wheels &c., transmits the motion to the machinery to be driven.
A series of such shafts may be employed, each jointed with a shaft provided
with a weighted arm as above mentioned, the upper ends of the several weighted
shafts being connected by a rod with crank arms on a horizontal shaft mounted
to turn in bearings in the frame, the several crank arms being placed equi-distant
on the shaft, so that the several shafts are turned successively.
The upper end of each shaft is also pivotally-connected with an arm pivoted to
the frame to guide the swinging motion of the said shaft. The lower several
shafts are connected with each other by belts, and the last shaft in the series is
connected by gear wheels with the driving shaft connected with suitable machinery
to be actuated by the motor.
When the crank shaft is rotated, the several crank arms and connecting rods
impart a turning motion to the shafts as previously described, so that they are
rotated and their aggregate power is thus transmitted to the driving shaft.

Improved Means for Transmitting Manual or other Motive Power
for Driving Machinery.
I FRANK WILLIS CLARK, of Mount Desert, in the County of Hancock and
State of Maine, United States of America, Stonecutter 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 :-
The object of the invention is to provide a motor of simple construction, which
is very effective in operation and arranged to uniformly transmit power to machines
to be driven.
The invention consists of a shaft connected by a joint with a second shaft
carrying a weighted arm and mounted to swing.
The invention also consists of certain parts and details, and combinations of the
same, as will be hereinafter described and then pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this
Specification, in which similar letters of reference indicate corresponding parts in
all the figures.
Figure 1 is a sectional side elevation of the improvement on the line 1-1 of
Figure 2;
and
Figure 2 is a plan view of the same;
Figure 3 is a sectional plan view of the joint on the line 3-3 of Figure 1;
Figure 4 is a sectional side elevation of a modified form of the improvement.
The improved motor is provided with a suitably-constructed frame A, carrying
a bracket B, in which is journaled a vertical shaft C, on which is keyed a bevel
gear wheel D, in mesh with a like gear wheel E, on a shaft F, journaled in suitable
bearings on the main frame A and carrying a hoisting drum H, or other machinery
to be actuated by the motor.
.
The upper end of the shaft C terminates in a fork C₁ supporting a plate I,
formed at its centre with an aperture I' to receive the square end J' of a shaft J,
standing normally in alignment with the shaft C, but adapted to be swung sidewise
out of aligument with the said shaft C, the reduced or square end J¹ being
sufficiently loose in the aperture I¹ to permit of such movement of the shaft J.
The shaft J is provided near its upper end with a collar J³ pressed on, on
opposite sides, by the free ends of springs K attached to the main frame A. The
extreme upper end of the shaft J is engaged by a lever L fulcrumed on the main
frame A and adapted to be actuated by hand or by suitable machinery such as-
the crank arm of an engine, to impart a swinging motion to the said lever L.
From the shaft J extends, at or nearly at right angles, an arm J' carrying at its
outer end, a weight J*.
The operation is as follows:
When the lever L is caused to swing, the weighted arm J', in trying to move-
to its lower position according to the inclination of the shaft J, causes the latter to
turn, until finally the arm J continuously swings round whereby a continuous
rotary movement is given to the said shaft J, and also to the shaft C, which lattér,
by means of the gear wheels D and E and the shaft F, transmits the motion to
the machinery to be driven.
The springs K tend to return the shaft J always to a normal vertical position.
As illustrated in Figure 4, a series of such shafts C may be employed, each con-
nected by a joint with a corresponding shaft J provided with a weighted arm J³.
The upper ends of the several shafts J are connected by rods N with crank arms O
secured on a shaft P mounted to turn in suitable bearings in the main frame A.
The several crank arms are placed equi-distant on the shaft P so that the several

page_text: shafts J are turned successively, as will be readily understood by reference to the
said Figure 4.
The upper end of each shaft J is also pivotally-connected with an arm R pivoted
on the frame A to guide the swinging motion of the said shaft. The several
shafts C are connected with each other by pulleys S, S¹, and belts S', and the last
shaft C in the series is connected by gear wheels D and E with the driving shaft F
connected with suitable machinery to be actuated by the motor.
When the shaft P is rotated, the several crank arms O and connecting rods N.
impart a turning motion to the shafts J in the manner previously described, so that
the several shafts C are rotated and as the same are connected with each other by
the pulleys S, S' and belts S', the aggregate power of the several shafts is thus
transmitted to the driving shaft F.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is,―
1. A motor comprising a shaft connected with the machinery to be driven, a
second shaft mounted to swing and pivotally-connected with the said first named
shaft, the said second shaft carrying a weighted arm, substantially as shown and
described.
2. A motor comprising a shaft connected with the machinery to be driven, a
second shaft mounted to swing and pivotally-connected with the said first named

described, for imparting a swinging motion to the said shaft carrying the weighted
arm, as set forth.
