Upon the bed-plate A is arranged a metal frame consisting of the supports B at
each end and the supports B³ between them. Near the lower part of the latter is
placed a shaft C on the ends of which are the pulleys C¹ by means of which the
power of any suitable motor such as steam, electricity etc. is transmitted to the
apparatus. Above this driving shaft is arranged a second shaft D on one end of
which is a flywheel D' and on the opposite end a pulley D2 through which, by
means of the strap D³, power is transmitted to any desired machines or
apparatus.
In addition to the driving pulleys C¹, there are arranged upon shaft C two
other pulleys E connected by straps with pulleys F' F' whose shafts are supported
in standards B¹ B². These are arranged on the opposite ends and sides of the
machine outside of the straps or the supports B, an arrangement which is
preferable though not indispensable.
The shafts as shown in Figs. 2 and 3 terminate at their inner ends at about
the middle of the apparatus and are provided with discs f¹ which carry crank
pins F
The pulleys F F rotate in the same direction but their cranks are placed at an
angle of 180° relatively to each other so that when one crank moves upwards the
other assumes the opposite direction and both simultaneously reach their lowest
and highest position. These cranks F2 serve to move or oscillate the bar G
supported on a knife edge bearing y upon the central support and kept in position
by a pin moving in a slot.
This bar forms the arrangement by which the power is transmitted from the
driving motor to the second motor which is required to supply the augmented
power. Before describing the separate connection between this bar and the second
motor I will explain more fully the construction and mode of working of the
latter.
Figures 1 and 3 show that in the end supports B near the upper end, shafts H
are arranged each of which is at one end provided with a pulley H' connected
with the small pulley D' on the flywheel shaft D. The relation as to size of these
pulleys H' to D is best such that pulleys D make four revolutions in the time
that the pulleys H¹ make one. Apart from the pulleys H₁ the shafts at opposite
ends inside of the frame are provided each with a pair of fixed arms extending in
opposite directions and forming a frame J. On the inner side of the latter are

page_text: arranged slides i on which heavy weights K slide backwards and forwards; these
lie on opposite sides of the shafts and are connected with each other by the rods k
so that upon each slide are mounted two weights so connected, as to move
simultaneously. The relative sizes of the weights, connecting rods and frame are
such that when one weight reaches the extreme outer end of the frame, the other
is near the shaft H on the opposite side. It is hence evident, that when the outer
weight at the end of the frame is above the shaft and therefore above the centre of
gravity, the revolution of the shaft is produced by reason of the increased weight
of the frame in this position, until the weight again reaches its lowest position in
the frame. In order to effect the starting of the driving wheel shaft by means of
the engaging arrangement previously described, it is only necessary to set up an
arrangement for raising the weights when they have reached the lowest position in
their motion, whereby the opposite weight is each time forced to the extreme
height of the frame until the shaft has revolved and the said opposite weight has
been brought to the lowest point of its motion in the frame, whereby frame J,
shaft H, and flywheel D' are set in motion.
In order to render possible this revolution of the shaft, the frame with the raised
weight must have passed beyond its dead point as shown in Fig. 1 on the right,
while the weight on the left side, which is in its lowest position is represented as
not yet completely in the position for being raised.
:-
For the purpose of maintaining the weights in their elevated positions, and for
releasing them both at the same time at the right moment and rendering possible.
their re-elevation pawls s are arranged upon the weights, which when motion takes
place engage in the teeth or recesses in the arms of the frame, as shown in
Fig. 4, .e. the pawl of the upper weight when downward motion takes place,
swings by reason of the load on its backward portion, in an outward direction,
while that of the lower weight for the same reason swings towards the arm, and
when the weight has been wound up and has reached its highest position, the pawl
falls into the tooth or recess ; and retains the weight in its position until the
corresponding arm is turned downwards and the position of the weight is changed.
Immediately after this the position of the pawls is also changed the upper one
swings outward, while the lower one swings towards the side of the arm.
In order to raise the weights in succession two lifting arrangements sliding in
guides at the end supports B are employed. These have the form of racks M M
the upper end of each of which is flattened or formed into a plate or table, upon
which the weights lie at the time of being raised, such a weight moving in a downward
direction, as represented on the right of Figure 1 will be made to swing across the
plate, and on the rack together with the plate or table being raised the weights
are taken along with the latter and will, before the frame in its revolution has
reached far enough to move them away from the rack, have been raised sufficiently
to enable the pawl to come into operation and retain them, at which time the
rack returns to its lower position, ready for a new stroke.
The weights may be raised or moved away from the beam or bar G as well as
from the Hywheel shaft by means of various arrangements. It is however
preferable to employ for this purpose levers with long and short arms loaded at
their ends, as for example the levers N N' which are supported in the bearings or
standards n. At the outer ends of the levers are arranged weights N2 while at the
inner or shorter end of the lever arms are provided toothed segments O the teeth
of which engage with the spur pinions O¹, while the toothed wheels (2 mounted
adjacent to the supports B engage in the teeth of the racks M M.
When one of the levers is swung it is evident that the racks M M must thereby
be moved up and down, and the weights N2 must be sufficiently heavy to effect this,
when the racks are free to move. This end is attained by having one of the two
weights N relatively lighter than the other in order to effect the motion of the
lever.
In order to bring the racks M M into the condition necessary for constantly
raising the weights at the right moment, it is only necessary to raise and release

page_text: the outer or longer arms of the levers and to allow the depression of these arms
to be effected by the levers themselves, or to regulate it by an appropriate
arrangement.
To effect this by the simplest means and the least possible expenditure of power,
links P are jointed to the beam G and outer ends of the weighted levers N N¹.
This construction is easily understood and from it is evident that the beam G has
the form of an open frame the lateral rods G¹ of which extend below the
oppositely situated weighted levers N N' of which latter, one together with the
mechanism actuated by it, is arranged at the front and the other at the back
part of the machine as shown in Figure 2.
The operation of the before described apparatus is as follows:--
Power is communicated by the strap C² to the shaft C and by means of the
latter to the pulleys F¹ F' together with the crank F2. The latter oscillates the
bar G, or frame G G', which on its side alternately raises and allows the weighted
levers N N' N2 to fall which thereby alternately raise the racks M M. These
motions are so adjusted that the lifting arrangements assume a position below the
weight K in the frame J, at the exact moment, when the weights have reached
their lowest position, and then raise them to their highest position, where their
accumulated energy is expended in the operation of the frame, which in its turn
drives the shaft H and the driving wheel shaft, connected with it by straps, from
which latter the power can be communicated to any machine it is desired to
drive.
To ensure the correct rotation of the slides one of the straps is crossed (the
left in Fig. 1) whereby both slide-frames will be made to swing outwards, although
this can be ordered at pleasure, the only thing unconditionally necessary being
that the weights should reach their lowest position at the moment when the racks
begin to move upward in order that these may raise them and leave them in a
position to exert their force upon the motor mechanism.
Having now particularly described and ascertained the nature of the said inven-
tion, as communicated to me by my foreign correspondent, and in what manner the
same is to be performed, I declare that what I claim is :-
1. An apparatus for augmenting the power of motors by the application of the
force of falling weights characterized by an arrangement of heavy bodies sliding
in rotating slides and retained in the latter until having passed the dead point by
automatically engaging and disengaging pawls substantially as described and
illustrated in the accompanying drawings.
2. In apparatus such as described mechanism for the raising of the weights in
their slides consisting of swinging levers moved by the driving agent which by
means of toothed wheels gear raise racks by which the elevation of the weights is
accomplished substantially as described and illustrated in the accompanying
drawings.
3. The combination and arrangement of parts constituting the complete
apparatus for augmenting the power of motive power engines substantially as
described and illustrated in the accompanying drawings.
