PROVISIONAL SPECIFICATION.
Improvements in Centrifugal Apparatus to be Moved by Fluids.
We NINIAN WOODS CURTIS of 15 Romberg Road Upper Tooting in the County of
Surrey, Engineer and ALFRED EDWARD CAREY of 9 Deans Yard Westminster in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this invention
to be as follows :—―
The object is to provide simple efficient and easily controlled apparatus in which
advantage is taken of centrifugal action to enable fluids to give motion to the
apparatus.
First. Apparatus to be operated by fluids so as to obtain motive power consists of
jet or similar appliances for projecting a mixture of steam and water in the form of
spray against a disc or discs provided with vanes free to rotate within a fixed case also
provided with vanes, or any equivalent centrifugal apparatus may be used.
Second. To regulate the flow of the fluid we combine a stop valve with screw and
spring retaining mechanism in such manner that the valve may be entirely closed by
the screw action or adjusted so that the spring will act to allow the requisite quantity
of fluid to pass.

COMPLETE SPECIFICATION.
Improvements in Centrifugal Apparatus to be Moved by Fluids.
We NINIAN WOODS CURTIS of 15 Romberg Road Upper Tooting in the County of
Surrey, Engineer, and ALFRED EDWARD CAREY of 9 Deans Yard Westminster in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this invention
and in what manner the same is to be perforined, to be particularly described and
ascertained in and by the following statement :-
The object is to provide simple efficient and easily controlled apparatus in which
advantage is taken of centrifugal action to enable fluids to give motion to the
apparatus.
First. Apparatus to be operated by fluids so as to obtain motive power consists of
jet or similar appliances for projecting a mixture of steam and water in the form of
spray against a disc or discs provided with vanes free to rotate within a fixed case also
provided with vanes, or any equivalent centrifugal apparatus may be used.
Second. To regulate the flow of the fluid we combine a stop valve with screw and
spring retaining mechanism in such manner that the valve may be entirely closed by
the screw action or adjusted so that the spring will act to allow the requisite quantity
of fluid to pass.
Figs. 1 and 2 are vertical sections at right angles to each other of a motor under
the first part of our invention fitted with the improved valve under the second part,
a is a fixed case, 6 cover to the case provided with a hearing for the spindle a,
e bearing within the case for the said spindle d, f disc or wheel with vanes g. The
case a is made with a chamber / provided with vanes i. j.j¹j' steam and water
supply pipes. The pipe j communicates with the interior of the case a which is
partly filled with water, the pipe j¹ opens to the air inlet way k provided with a

a spindle n free to move to and fro through a nut and hand wheel o. p spring
abutting against the spindle collar n', and nut collar o¹, 7 guides, nut on end of valve
spindle. perforations opening from the pipe j' into the interior of the case a, t inlet
pipe for water, u outflow."
The action of the apparatus is as follows:-The hand wheel is turned until the
spring p is so far compressed as to force the valve m from its seat against the steam
pressure at the back thereof. Steam then flows through the pipe into the pipe j'
and draws water at a high temperature through the openings 8.
The mixed steam
and water then pass in the form of spray into the pipe and a further supply of
water is drawn up between the pipes and j the whole being impelled past the
vanesi. of the case against the vanes g of the disc or wheel. The water in the case a
is kept at the requisite temperature by means of a regulated inflow at t and outflow
at u. The spring p acts as a regulator on the valve m to control the passage of steam
into the apparatus.
Fig. 3 is a section of a modification of apparatus in which a single inlet jet pipe j'
is used, and water is drawn up a suction pipe j.
It will be obvious that many modifications of centrifugal motors may be made under
our invention.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed I declare that what
I claim is :-
First. Apparatus for obtaining motive power by the action of a mixture of steam
and water in the form of spray substantially as set forth.
Second. Apparatus for obtaining motive power consisting of a disc and
case
provided with vanes and steam and water supply ways combined and operating
substantially as setforth.
Third. Stop valves combined with screw and spring gear substantially in the
manner and for the purpose setforth.
