I NINIAN WOODS CURTIS of Jessamine House, 33 Meeching Road Newhaven
Sussex Engineer, do hereby declare the nature of the said invention for "IMPROVE-
MENTS IN MOTIVE POWER ENGINES" to be as follows:-
The invention relates to combined steam and hydraulic engines for pumping,
driving machinery, and other purposes, and the object is mainly to increase the
efficiency of such engines.
The invention consists. First. In constructing a motor in such manner that
steam and water act in separate compartments on opposite sides of suitably shaped.
vanes on a revolving wheel or turbine and come into contact with each other in a
discharge chamber.
Second. In combining with a high pressure steam engine a motor constructed as
above setforth so that the steam from the engine will exhaust into and be condensed
in the motor.
:-
Apparatus under my invention may advantageously be made as follows
A wheel, with a central disc web is made at each side with compartments divided
by vanes so as to have central and circumferential openings, is fitted within a
chamber of suitable shape on a central shaft carried on bearings mado with or
secured to the said chamber. At each side of the chamber is a way or ways
leading to the centre of the compartments of the wheel. The way or ways on one
side conduct water to one set of compartments and the way or ways at the other
side conducts steam to the other set of compartments. At the bottom of the
chamber an exhaust or discharge way and valve are provided.
The action is as follows:-Steam enters one set of compartments, and water the
other set on opposite sides of the disc, they both assist to give rotary motion to the
said wheel when issuing from the circumference of the said wheel into the chamber'
where condensation takes place. The condensing water and water of condensation
flow away through the exhaust or discharge orifice.

I NINIAN WOODS CURTIS of Jessamine House Meeching Road, Newhaven
Sussex, 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:—
The invention relates to combined steam and hydraulic engines for pumping
driving machinery and other purposes and the object is mainly to increase the
efficiency of such engines..
"
The invention consists First-In constructing a motor in such manner that
steam and water act in seperate compartments against suitably shaped vanes
on opposite sides of a disc or, web, of a revolving wheel or turbine and come into
contact with each other in a discharge chamber. To prevent the bearings becoming
too highly heated the temperature of the steam should be regulated by saturation
with water vapour-or otherwise as may be found, convenient. before it enters the
motor.
Second In combining with a high pressure steam engine a motor constructed
as above set forth so that the steam from the engine will exhaust into and be.
condensed in the motor.

Apparatus, under my invention may advantageously, be made as follows:-
A hollow wheel with a central disc or web is made at each side with compartments
divided by vanes so as, to have.central and circumferential openings and is fitted
within a chamber of suitable shape, on a. central-shaft carried on bearings made or
secured, to the chamber. At each side of the chamber is a way or ways leading to:
the centre of the compartments of the wheel. The way or ways on one side.
conduct water to one set of compartments and the way or ways at the other side
conducts steam to the other set of compartments... At, the bottom, top, or other
suitable part of the chamber an exhaust or discharge way and valve are provided....

... DESCRIPTION OF THE DRAWINGS. t

Fig. 1. is a vertical section and Fig. 2 a horizontal section of a motive, power
engine constructed in accordance with my invention. a. a are a chamber and
cover preferably of cast iron bolted together and provided with bearings 6 which
carry a spindle c. On the spindle c is secured a hollow wheel d having a central
disc or web e. which divides the interior of the wheel into two compartments f. f
The compartments f. f1 are again subdivided by, vanes g., which have, ways or
passages from the eyes h. h¹ of the wheel to the circumference.
The circumference of the wheel opens to the annulus i of the chamber a. At the
eyes the sides of the wheel & fit the chamber a. a¹ so as to make a close joint
between the wheel and the passages j. j leading from-the centre of the chamber and
cover to the water and steam supply pipes k. k. A communication / controlled by
a cock m is made between the water and steam supply pipes, n is the discharge
way leading from the annulus i past the clack valve o.

page_text: The action of the apparatus is as follows:-Steam saturated with water to the
extent required by means of opening more or less the cock m to the communication
way passes by the passage j to the compartment f. Water at the same time flows
by the passage to the compartment f¹. The impact of the steam and water
against causes the wheel to rotate and as the said steam and water on their
onward course meet in the annulus i the steam is condensed and with the water
flows out of the discharge way n past the valve o.
The motor above described is advantageously combined with a steam engine of
ordinary type, the exhaust steam from such engine being led through the pipe k to
the motor. The motor then acts both as a low pressure cylinder and condenser and
may very effectively be used where ever a condenser is required.
It will be obvious that by giving motion to the spindle the motor may be used
as a pump, but it does not possess the special advantages for this purpose that
it has when it is used as a combined motive power engine and condenser.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
First. Motive power engines in which steam and water act in seperate compart-
ments in a wheel or turbine and come into contact within a chamber.
Second. A motive power engine consisting of a chamber, a hollow wheel with a
dividing disc and vanes and suitable supply and discharge ways for steam and
water.
Third. The combination of a motive power engine constructed substantially
as herein set forth with a high pressure steam engine.
Fourth. A motive power engine constructed substantially as herein set forth
applicable as a condenser or pump.
