page_text: I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E. of the Agency for Foreign
Patent Solicitors of 6 Lord Street, Liverpool, and 6 Bank Street, Manchester, both
in the County of Lancaster & 323 High Holborn in the County of. Middlesex,
Civil Engineer, 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 :-
This invention relates to improvements in motors.
By this invention the expansive force of steam or compressed air is applied to a
motor wheel through the medium of water or other suitable liquid, which liquid is
caused thereby to flow with great force in a continuous stream repeatedly over and
over again in the same direction upon a motor wheel.
While the motor is equally adapted to be used with compressed air acting upon
other liquids than water, it is for brevity of description referred to and described as a
hydro steam motor.
Figure 1, of the accompanying drawings, represents a front view of the motor part
in section.
Figure 2, represents a vertical section drawn at right angles to that shown in
Figure 1 and
Figure 3 represents a horizontal section drawn on line x x of Figure 2.
Like parts are represented by the same reference letters throughout the several
views.
A & B are water receivers formed in a single casting and sub-divided into two
compartiments by a partition; two separate cylinders may, however, be substituted
[Price 8d.]

page_text: therefor. C is the motor wheel. The most approved form of turbine wheel being
preferred. D is the wheel enclosing case which is securely attached to the upper end
of the receivers A and B with which it communicates through two inlet pipes E E,
and two outlet or dis-charge pipes F F. The wheel case D is sub-divided into two
compartments a, b, by the partition G and the wheel C is located in the opening
formed therefor in said partition G. Both of the inlet pipes E E communicnte with
the front compartment a, of the wheel case from the respective receivers A and B in
front of said motor wheel, and both of the outlet pipes F F communicate from the
rear compartment 6 at the dis-charge side of said wheel back into said water
receivers A, B, respectively. The front or inlet pipes E E are provided with inward
opening check valves H H, which are alternately opened and closed as the water is
forced through said pipes E into the front compartment a, one of said valves H being
closed as the other is opened. The discharge pipes F F are respectively provided with
outward open check valves I I, which are alternately opened and closed. Preparatory
to operating the motor, one of the water receivers is filled with water. The receiver Å
being filled with water, the steam is admitted through the pipe A', and steam con-
trolling mechanism to such receiver, whereby the water is forced from said receiver A
through the outlet pipe E, into the front compartment a of the wheel case, when it
is driven with a force corresponding with the steam pressure through the wheel C
into the compartment b, when it passes down through the dis-charge pipe F into the
other water receiver B. The course of the water is thus continued until the contents
of the receiver A have passed into the receiver B when it is reversed from said
receiver B, to the receiver A by reversing the course of the steam from said receiver A
to the receiver B. When the steam pressure is thus reversed, the water in passing
from such receiver B back to the receiver A flows through the outlet pipe E of such
receiver into said front compartment a, and is again driven through the motor wheel C
as before, and dis-charged into the receiver A. Thus the same water is caused to flow
in a continuous stream upon the motor wheel with great force over and over again,
passing alternately from the receiver A to receiver B, and back again from receiver B
to receiver A, as long as the steam pressure is thus applied thereto. When the
pressure is applied within the receiver A, the valve I in such receiver is retained in a
closed position by such pressure, when the valve H above such receiver is opened at
the same time the valve I in receiver B is opened, and the valve H above said
receiver B is closed, and as the pressure is reversed from said receiver A to the
receiver B, the positions of said valves are also reversed by the action of the water.
The steam is controlled in its course both to and from said water receivers by a
reciprocating slide valve J, operating in a steam chamber K. Motion is commu-
nicated to the reciprocating valve J by the action of the weights H³, H', located in
the receivers A and B.
Both of said weights H₁ H' are suspended from the same
lever R by the rods L, L, and chains L', L which lever is centrally pivoted upon the
pin S. a, a, are stuffing nuts surrounding. the protuding ends of said rods L, by
which the escape of steam is prevented. The weights H'H' are of equal bulk and
gravity, and they counterbalance each other upon the supporting pivot S, owing to
which fact the gravity of one counteracts the gravity of the other, so that they
virtually weigh nothing, and consequently they may be made of solid iron or any
other material, preferably of greater specific gravity than the surrounding water. It
will therefore be obvious that when the water. in the receivers A and B stands above
and surrounds both weights, as is the case the greater part of the time during the
transmission of the water from one receiver to the other, the weights remain at rest,
but as soon as the water descends in one of said receivers below the weight therein,
said weight will gradually descend, while the counter-balancing weight will ascend.
It will be obvious that as one of said weights is surrounded with water, and the other
is suspended in the empty receiver, the gravity of the weight in the empty receiver
will exceed that of the full receiver, and the same will be drawn downward in the
empty receiver with a force equal to the weight of the water displaced by the opposite
weight, whereby one end of the lever R will be drawn: downward, and the other end
upward by the descending weight, with a force equal to the weight of the water

page_text: displaced by the weight in the full receiver. Thus it will be obvious that said weights
will be caused to rise and fall, and said lever R to oscillate upon its pivotal support,
as said water is alternately driven backward and forward from one of said water
receivers to the other. The motion of the lever R, as it thus oscillates, is com-
municated to the steam controlling valve J as hereinafter described, whereby said
valve J is caused to reciprocate horizontally across the steam controlling ports d d
and e.
The ports d, d, communicate between the valve chamber K and the respective
water receivers A and B, whereby as said valve J reciprocates backward and forward,
communication is alternately opened between the valve chamber K and the respective
receivers, while the same movement of the valve J, which opens communication to
one of the receivers A or B, also opens communication between the other receiver
and the exhaust duct E¹ thus permitting the steam to escape from one of said water
receivers, as the water is driven into the same from the other reciver. One side of
the lever R is provided with two stops g, g, which, as said lever oscillates, are brought
in contact with the respective sides of weighted two armed lever A', whereby said
lever A¹ with its weight B' is carried upward from the inclined position shown in
Figure 1 to, and slightly past the vertical, above the pivotal support S as said lever R
is moved as heretofore described by the action of the weights H. When said lever A¹
is thus carried to, and slightly past the vertical as mentioned, it drops of its own
gravity upon the other side, whereby a quick positive motion is produced, which is
communicated by the short arm, of said lever through the stops D¹, D¹, lever F¹,
shaft G', and the segment gear H¹ to said reciprocating valve J. The upper surface
of said valve J is provided with a series of cog teeth, which are meshed into and
moved by the gear segment H as the same is moved. The lever A' is supported and
turns upon the same pivotal support S with the lever R. The shaft G¹ extends across
the interior of the valve chamber K, and protrudes therefrom forward through the
stuffing nut I'. The gear segment H" is rigidly affixed to the shaft G1 on the inside
of the chamber K, and the lever F¹ is rigidly affixed to the exterior end of the
shaft G. The stops D' D' are located at a slight distance apart from each other upon
the respective sides of the lever F1, whereby the valve J is permitted to remain at
rest during the greater part of the movement of the lever A¹, and until said lever A¹
has commenced to drop of its own gravity past the vertical, when said valve J is
given a quick positive movement. To maintain a continuous unbroken pressure of
water upon the wheel during the brief interval that the steam controlling valve is
reversing, an air chamber D₁ has been provided, which holds a quantity of water
beneath compressed air in said chamber, which water is driven by the compressed air
therefrom down into the compartment a, of the wheel enclosing case as soon as there
is any diminution of pressure therein, whereby a steady uniform movement is given
to the wheel. To prevent the steam from coming in direct contact with the surface
of the water, and the condensation which would thereby occur before the water has
become heated, floats U, U, have been provided, one in each water receiver A and B
having an aperture through their centres for the reception of the rods L, L, which
floats U, U form a partition between the steam and water, and serves to greatly
reduce the condensation that would otherwise occur when starting the motor with cold
water.
When operating the motor with steam, there is a gradual accumulation of water
from condensation, which is permitted to escape from one or both of the receivers A
and B through the escape valve J¹ and pipe K'. The valve J is hinged to its
chamber M, M, above its seat, and is provided with an arm N, which extends inward
and upward to near the upper extremity of the water receiver, where it is acted upon
and raised by a float as the water rises round it. The float may be permanently
attached to the arm N if desired, but when the float U is used, it will, as it rises with
the surrounding water, be brought against the lower side of said arm N when said
arm will be raised, and thus open the valve J when the accumulated surplus of water
will escape. When the steam pressure is reversed to said receiver, the valve J will be
gradually closed as the float U descends with the descending water, and the surplus
water will continue to escape until the valve is permitted to close.
