Improvements in Fluid Pressure and Hydraulic Motors.
I, SUMTER BUREGARD BATTEY, (Physician) of No. 124 West Thirty-sixth Street,
New York City, in the County and State of New York, United States of America,
d hereby declare the nature of my invention and in what manner the same is to
he performed, to be particularly described and ascertained in and by the following
description:
The object of the invention is to provide a new and improved fluid pressure and
hydraulic motor, arranged to utilize the motive agent to the fullest advantage and
without any waste or loss of water.
The invention consists principally of a wheel formed in its periphery with
conduits, buckets or pockets, a pipe surrounding the wheel and formed with nozzles
for discharging the water under pressure into the said buckets, a vessel adapted to
contain water and connected with the said pipe, and a pressure pipe for the said
vessel, for forcing the water out of the vessel into the wheel pipe and through the
nozzles thereof into the buckets, to rotate the said wheel.
The invention further consists of a tank connected with the motor casing, to
permit the water to flow from the casing to the tank, a vessel within the said tank
and connected with the supply pipe for the motor, a valved connection between the
tank and vessel, and a pressure pipe opening into the said tank, to force the water
therein quickly into the said vessel.
The invention also consists of certain parts and details and combinations of the
same, as will be fully described hereinafter and then pointed out in the claims.
Reference is to be had to the accompanying drawings forming a part of this
ecification, in which similar characters of reference indicate corresponding parts

The improved motor is provided with a casing A, preferably made circular in
rm and preferably containing two motor wheels B, arranged one alongside the

page_text: other, and both secured on a shaft C, journaled in suitable bearings in the beads
of the casing A, one outer end of the said shaft carrying a pulley C¹ for trans-
mitting the rotary motion of the wheel to other machinery. Each wheel B is
surrounded on one side by a pipe D formed with nozzles D₁ adapted to discharge
water in a tangential direction, in conduits, pockets or buckets B₁, formed in the
periphery of the wheel B. Each bucket B₁ is provided on one side with an
outlet B² extending to one side of the wheel and curved laterally backward in the
inverse direction to the movement of the wheel. The forward wall B³ of the
bucket B is serrated or formed with teeth extending transversely along the wall
from near the entrance B to the end of the outlet 132, as plainly shown in Figure 6.
The entrance B to the conduit is in the form of a groove arranged somewhat at
one side of the wheel rim, and is gradually increased in depth, as will be understood
by reference to Figure 3.
It is evident that when a fluid under pressure passes in a tangential direction
from the nozzles D' through the entrance 13+ into the conduit B¹, it presses against
the teeth of the wall 33 to revolve the wheel in the direction of the arrow a
(Figure 2). By having the teeth in the wall 133 the fluid under pressure impinges
successively on the edge of the teeth, to insure a full utilization of the motor power,
and at the same time a proper forward and transverse movement of the fluid.
When the latter passes into the gradually widening outlet B, then a reaction of
the fluid begins, to insure further impulses on the teeth at the outer end, to revolve
the wheel in the direction of the arrow al.
The pipe D is held on trunnions D2, D3, arranged in the rim of the casing A,
so that said pipe can swing to move the nozzles 1 into or out of alignment with
the entrances B to the conduits, so as to cut off the fluid whenever the wheel runs
above a normal rate of speed. This movement of the pipe D is controlled by a
governor, in a manner hereinafter more fully described.
For reversing purposes, I employ the two wheels B as mentioned, but the
buckets B of one wheel- and the corresponding nozzles D' stand in opposite
directions to the buckets and nozzles of the other wheel, so that when water is
forced into the buckets of one wheel, the latter and the shaft C are rotated in one
direction; and when the water is forced into the buckets of the other wheel, the
latter and the shaft C are turned in the reverse direction. One of the wheels B is
Guly used at a time to turn the shaft C in the corresponding direction. The
trunnions D2 for the two wheels B are hollow and in the form of pipes (see
Figures 3 and 5) and contain valves D and 16, adapted to be shifted by the
operator to open either of the two pipe trunnions 12 and close the other, or close
both whenever it is desired to stop the motor. The trunnions 12 connect with a
bex E, connected with supply pipes F and F normally closed at their upper ends
by upwardly opening valves E, E, as plainly shown in Figures and 4. The
supply pipes F and F are connected with the bottoms of vessels G, G', adapted to
contain water or other liquid to be forced through the said pipes into the box, E,
and from the latter through either of the pipe trunnions 12 into the corresponding
pipe D, buckets D¹, to the corresponding wheel B or B to rotate the same.
the upper ends of the vessels G and G₁ lead the pressure pipes I and I' respectively,
connected with a common supply pipe 12 containing a valve I³, connected with a
boiler or other source of steam, air, or gas supply, to permit the steam, air, or other
fluid to pass under pressure into the upper ends of the said vessels G and G¹.
Into
In the pipe I is arranged a governor valve J actuated by a governor K driven
from the shaft C to regulate the amount of steam, air or other fluid passing through
the pipe I to the pressure pipes I and I. The valve J is also connected with the
pipes D to tilt the same to form a cut-off of the motive agent for the buckets of the
wheels D, as hereinafter more fully described.
The pressure pipes I and I are provided with branch pipes I and 15 respectively
opening into the upper ends of the tanks H' and I respectively to exert a pressure
on the water contained in the said tanks to force the water quickly into the
vessels G. and G₁ by way of their ports a and b and the gate valves G2 and G³

page_text: respectively (see Figure 10), mounted to turn in the said vessels to and from the
said ports to open and close the same, as hereinafter more fully described.
From the lower end of the casing A leads the outlet pipe L connected by the
branch pipes L' and L² with the tanks H and H₁ respectively, so that the water
discharged from the wheels B or B flowing into the casing A passes by the
pipes L, L, L2, back into the tanks H and H' to be finally forced into the vessels G.
and G¹ for re-use. In the pipe L is arranged a partition or diaphragm L³ extending
a short distance up into the casing A and leading to the entrance of the branch
pipes L' and L2, so that the water flowing down the pipe L is equally distributed
to the branch pipes L' and L2 to fill the tanks H and H uniformly.
In the pipes I and I are arranged slide valves N.and.N respectively, -pivotally
connected at their valve stems N2 and N with abutments N and No respectively,
connected with a crank arm 0, secured on a transversely extending shaft O¹
journaled in suitable bearings and carrying a worm wheel P in mesh with a
worm P, having its shaft P2 provided with a pulley P³, connected by a belt P4
with a pulley 15, attached to the shaft C. Thus when the latter is rotated, the
pulley P transmits a rotary motion by the belt P and pulley P3 to the shaft Pa
and worm 1"; which, in turn, rotates the worm wheel P and causes the crank
arm to simultaneously shift the valves N and N' in such a way that one opens
and the other closes and vice versa.
In the branch pipes I and I are arranged valves Q and Q respectively, adapted
to be turned to open and close the said pipes so as to connect and disconnect the
tanks H' and H with and from the pipes I and I respectively. The valves Q and Q'
are secured on vertically disposed valve stems Q2 and Q3 respectively, mounted to
turn in suitable bearings and carrying at their upper ends arms Q and Q, adapted
to be engaged by a cam groove formed on the peripheral surface of a cam 02, secured
on the shaft O, the said cam being adapted to shift a yoke 03 fitted to slide in
suitable bearings, as indicated in Figure 1. The yoke (3 is provided on opposite
sides with racks 0 and 05 in mesh with gear wheels G and G respectively on the
upper outer ends of the valve stems and G5, carrying the gate valves G2 and G³
respectively.
Now it will be seen that when the cam 02 pushes the yoke O to the left, as shown
in Figure 1, the two racks 0 and 0 rotate the gear wheels G and G simul-
taneously in such a manner that the valve G2 closes the port a in the vessel G,
while the other valve (opens the port in the vessel G to allow the water
contained in the tank II' to flow into the said vessel G and fill the same.
When the yoke O moves to the right, the above-described operation is reversed;
that is, the valve G3 is moved into a closed position over the port while the
valve G2 is moved into an open position to allow the water in the tank H to flow
through the port a into the vessel G to fill the same. Thus it is evident that the
valves N, N', I, I', and G³, 68, are all actuated simultaneously from the shaft O¹.
as above described.
In order to insure a rapid filling of the vessels G and G when their valves are
open as above mentioned, I provide the said valves with ports c and d respectively
adapted to register with pipes G8 and G leading from the top of the vessels
through the tops of the tanks H, H', to the outside. Now when the pressure is
shut off from the vessel G or G₁ by closing the valve N or N¹ respectively, then
the ports c or d are in register with their pipes G, GP, so that when the valve
moves into an open position, atmospheric air is admitted into the vessel to allow
the water from the tank H or H' to fill the same rapidly. It is understood that
the said ports and pipes relieve the vessels G, G¹, of any pressure.
The valve J controlled by the governor K, is in the form of a gate, as plainly
shown in Figure S, and this gate valve is connected by rods J with a collar 12
loosely engaged by a flange K' formed on a vertically disposed pinion K, mounted
te turn loosely and to slide vertically on the governor stem K held on a suitable
bracket. The pinion K² is in mesh with a worm R, secured or formed on a shaft R
carrying at one end a pulley R³ connected by a belt R³ with a pulley R attached to

page_text: the reduced end Ca of the main driving shaft C (see Figure 1). Thus when the
latter is rotated, a rotary motion is given by the pulleys R, R and belt R³ to the
worm shaft R¹ and its worm R, to revolve the pinion K². The latter is connected
at its upper ends by links K with the governor weights or balls K³, pivotally
connected by links K with a collar K' mounted to turn loosely on the upper end
of the governor stem K³, said collar also resting on a shoulder K8, secured to the
said stem. The pinion K³ is of considerable length, so that when the balls Kō
open on an increase of speed, the said pinion still remains in mesh with the
worm R.
It is evident that when the speed increases and the governor balls fly outward,
they draw the pinion K2 upward, and the flange K' of the pinion in acting on the
collar Ja leaves the gate-valve J to cut off the steam passing through the pipe I'
into the pressure pipes I, I¹. The pressure on the water in the vessels G, G³, is
thus controlled by the governor driven from the motor, and consequently the
motive agent for the motor wheel B is reduced in pressure until the wheel attains
again its normal rate of speed.
The lower end of the gate-valve J is provided with a downward extension J³,
pivotally connected with a bell crank lever S, connected by a link S¹ with the
pipe D, so that when the gate-valve J is lifted on an increase in speed of the
wheel B, the pipe D is tilted by the action of the gate-valve on the bell crank
lever S and link S¹, to insure a cut off of the motive agent on the wheel B, as
previously explained.
The pipe D is provided between the nozzles D₁ with valves D*, the stems of
which extend to the outside of the casing A, as is illustrated in Figure 1, to permit
of cutting off water from any desired number of nozzles, according to the desired
speed.
In each of the pipes I and I¹ directly below the corresponding valve N and N',
is arranged a pressure regulator, shown in detail in Figure 13, and comprising a
slide valve T, adapted to move in and out of the pipe to regulate the amount of
air passing through the pipe to the corresponding valve stem with one end of a
lever T pivotally connected at its other end with the piston rod T2 of a piston T³
fitted to slide in a cylinder T* closed at its outer end and opening at its inner end
into the corresponding pressure pipe I or I¹. A spring T5 is connected at one end
with a slide Te held adjustable on the lever T", next to the valve T, and the other
end of the said spring T is connected with a slide T' held on a graduated rod T³.
It will be seen that by moving the slides T and T6 upward or downward more or
less force can be exerted by the spring T5 on the piston T3, which is actuated by
the pressure within the pipe I' and, consequently, the valve T can be set to the
desired pressure by adjusting the spring. To accordingly.
When the pressure increases in the pipe I or I¹ beyond the normal or a desired
pressure, the piston T3 is then forced outward to impart a swinging motion to the
lever T, so that the latter pushes the valve T inward to cut off the air in the
pipe I or I', and when the pressure is again normal, the spring T5 returns the parts
to their normal position.
In order to increase the efficiency of the air when used as a motive agent
passing through the pressure pipes I and I', I provide a heating device for each
pipe I or I¹, as shown in Figure 12. This heating_device consists principally of
a pipe U arranged concentrically within the pipe I or I¹ and having its lower
end U passing through one side of the pipe I or I¹ to the outside, the upper end
of the pipe U extending likewise through the wall of the pipe I or I¹ to the outside
thereof to form a chimney U³, as shown. In the lower enlarged end of the pipe U
is arranged a burner U³, connected by a pipe U¹ with suitable oil supply used as
fuel for the said burner, the latter delivering its flame through the chimney Us
suspended over the burner and connected with an air supply pipe U6 opening
into the corresponding pipe I or I¹. Thus a large amount of air under pressure
can pass through the pipe U6 to the burner U³ and chimney U5 to insure a proper

page_text: burning of the flame, so as to heat the pipe U, say to a red heat, the products of
combustion passing through the chimney 2 to the outside.
Now it is evident that air passing through the pipe I or I¹ comes in contact with
the external surface of the pipe and takes up heat to increase its expansive
force to a considerable degree before passing into the vessel G or G₁ to act on the
water therein.
In starting the machine the burner U³ is heated by a small flame of burning oil
passing through a pipe U7, connected with a tank Us, the end of the pipe U'
forming a burner located below the burner U³. The oil, passing into the burner U³
is thus readily volatilized to insure a proper flame in the chimney U³.
The valves D and D in the pipes 12 are manually set by the operator, and for
this purpose I prefer the mechanism shown in detail in Figure 5. The connected
valve stems of the valves D and D6 support a pin D engaging a slot in the lever V,
pivotally connected with a link V₁, connected with the slides V3 and V+, fitted to
slide in suitable guideways V5 and V6, and the outer surfaces of the said slides are"
preferably curved to be engaged by the peripheral surfaces of a cam V7 secured on
the lower end of a shaft V8, carrying at its upper end a hand wheel V under the
control of the operator.
It will be seen that when the hand wheel V9 is turned, the cam V' will push one
slide Vor V3 outward, and as this slide is connected by a link V¹ with the other
slide, the latter is drawn inward and a swinging motion is given to the lever V by
the said link to shift the valves D5, D6, simultaneously into open and closed
positions, as above mentioned.
The operation is as follows:
When the several parts are in the position as illustrated in Figure 1, the air or
a like fluid passing through the pipe 12 passes into the pressure pipe I, as the
valve N therein is opened, the air passing from the pipe I into the vessel G to
force the water therein through the pipe F into and through the box E, into the
pipe D or D, and through the nozzles thereof to the wheel B or B¹ to rotate the
lotter, as previously explained. The water that flows from the working wheel B
or B flows from the casing A through the pipes L, L' and L2 into the tanks H, H¹.
The water contained in the tank 1 fills the vessel G¹, as the valve G³ thereof is
opened. When the vessel G is almost empty of water, then the cam 02 shifts the
yoke 03 to the right, so that the valve N is closed and the valve N is opened, the
valve G2 is opened and the valve G3 is closed, and the valve Q is opened and
valve Q¹ is closed. Thus the air from the pipe 12 can now pass through the pipe I¹
into the vessel G¹ to force the water therein through the pipe F to the working.
water wheel B or B¹, so as to further rotate the same in the desired direction. The
water contained in the tank H fills the vessel G, as the valve G³ thereof is now in
an open position. When the vessel G₁ is nearly empty, the yoke 03 is again shifted
to the left, back to its former position, and the valve G2 is closed and the valve G³
open, and the position of the valves N, N¹, is shifted; so that the pipe I' is closed
aud the pipe I is again opened.
The above-described operation is then repeated.
It will be seen that by the arrangement described, the air pressure is utilized to
force the water into the pockets of the wheel B or B³, so as to rotate the same, it
being understood that the direction of the shaft C depends on the use of either the
wheel B or B¹.
In order to insure a continuous rotation of either of the wheels, I provide the
two sets of vessels and tanks with automatic gates, so that no interruption whatever
takes place in rotating the wheel B or B' as long as the valve I³ is opened.
It will further be seen that the air in passing through the pipe I or I' takes up
heat so as to increase the expansive force of the air, and thereby insures an
expelling of the water from the vessel G or G¹ with considerable force to rotate the
wheel B or B correspondingly at a high rate of speed. It will further be seen that
the motor utilizes the motive agent to the fullest advantage and without any waste

page_text: or loss of water, as the latter flows directly from the casing A back into the
tanks H, H', to be forced into the vessels G, G, and back to the motor, as above
described.
