Improvements in or Appertaining to Fluid-power Motors, also
Applicable in part for Pumping Liquids.
A communication from abroad by JAMES B. ERWIN, of 256, 24th Street, Milwaukee,
Wisconsin, United States of America.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both in
the County of Lancaster, and 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 steam engines, and it pertains to that
class in which the power of the steam is converted into mechanical energy through
the repeated use of the same water or other liquid acting continuously upon an impact
or turbine water wheel.
By this improvement, the same water is driven, by a piston, from one end of the
same cylinder to the other, and as it passes from one side of the moving piston it is
forced in contact with the motor wheel within a wheel enclosing case from which case
it is conducted back to said cylinder upon the opposite side of said piston, whereby, as
said piston reciprocates, the same water is caused to flow in the same direction
continuously upon the motor wheel thereby communicating to said wheel a rapid
rotary movement.
The invention may be explained by reference to the accompanying drawing which
represents a side view thereof.
As a device for thus forcing the same water continuously in the same direction upon
a motor wheel, there is employed a steam actuated force pump of the ordinary con-
struction consisting of a substantial frame A, steam cylinder B, steam chamber (
provided with ordinary steam controlling valves, water cylinder D, water chamber E
provided with ordinary water controlling valves and piston rod F connecting together
the pistons of the respective cylinders B and D, all of which parts are constructed and
arranged relatively to each other in the ordinary manner. H is the inlet water duct
to the water cylinder through which water is led alternately upon the respective sides
of the piston therein as said piston reciprocates from one end of the cylinder to the
other. I is the outlet water duct through which the water is forced in a continuous
stream from the chamber E upon the water wheel. J is the water wheel, which, in
the form shown, is a so-called impact wheel. The wheel J is enclosed and supported
in place by the enclosing case or frame K. The discharge end or nozzle S of the
outlet duct I is connected with the wheel case K in such a manner that the water as
it is discharged therefrom is brought with great force upon the motor wheel whereby
said wheel is caused to rotate with great speed with and upon its supporting shaft L.
The inlet end of the inlet water duct H is connected to or communicates with the
wheel case K whereby as the water escapes from said wheel it is led back and returned
to said water cylinder. Thus it is obvious that the same water is caused to flow
continuously over and over again upon said motor wheel as mentioned with each
reciprocating movement of the piston. If it be desired to do so the invention
may be used as a pump for elevating or forcing water in the ordinary manner,
in which case the water cylinder is connected with a cistern or water reservoir
in the ordinary manner through a water duct A¹ which is provided with an
ordinary valve B' by which said pipe may be closed when desired. The water
chamber E is also provided with an outlet duct C through which water may be
forced upon a fire or elevated as may be required. The duct is provided with
water controlling valve D¹. The water duct I is also provided with a water
LD 217

page_text: controlling valve F¹ and the return duct H is provided with water controlling
valve G. Thus it is obvious that when it is desired to use the device for pumping
water, the valves G¹ and F¹ are closed, and the valves B₁ and D₁ are opened,
when, as the machine is operated, water will be drawn from a reservoir through
the pipe A and forced out through the pipe (. When, however, it is desired
to use the invention as a motive power for driving machinery, the valves B1 and D¹
are closed and the valves F1 and G₁ are opened, whereby the water contained in the
cylinder D and water chamber E is driven with great force continuously through the
discharge nozzle S upon the wheel J as described. T is a steam controlling governor
of the ordinary construction which is driven from the shaft. L through the belt V
whereby the admission of steam is regulated by the speed of the motor wheel and a
steady uniform movement of such wheel is attained.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is :-
1. The combination of a steam actuated force pump, a water wheel, a wheel enclosing
case, a water duct communicating from the water cylinders of said force pump to and
adapted to discharge the water from said force pump upon said water wheel, and a
water duct communicating from said wheel enclosing case back to said water
cylinders, all substantially as and for the purpose specified.
2. The combination of a steam actuated reciprocating force pump, an impact or
turbine water wheel J and wheel enclosing case K, a water discharge duct I communi-
cating from the water cylinders D of said pump to said water wheel, an inlet water
duct H communicating from said wheel case back to said water cylinder, a steam
controlling governor T, a driving belt communicating from said governor with the
shaft L of said motor, substantially as and for the purpose specified.
3. The combination of a steam actuated reciprocating force pump, an impact or
turbine water wheel J, a wheel enclosing case K, a water discharge duct I communi-
cating from the water cylinder of said force pump to and adapted to discharge the
water upon said water wheel, an inlet water duct H communicating from said wheel
enclosing case back to said water cylinder D, an inlet water duct A communicating
from an exterior water reservoir through a water controlling valve B' with said water
cylinder and an outlet water duct C provided with a water controlling valve D', a
substantially as and for the purpose specified.
