[Communicated from abroad by WILLIAM FROST, of Kimberley, South Africa,
Engineer.]
An Appliance for Utilising Force of Steam or other Fluid on its
way to Work an Engine.
I, RICHARD LEWIS COUSENS, of St. Georges Club, Hanover Square, in the County
of London, Electrical Engineer, do hereby declare the nature of this invention to be
as follows:
According to this invention the engine shaft is connected to a cylinder which
revolves within a casing. The working fluid, on its way to drive the engine, enters
the central part of this cylinder in which cylinder there is formed an expanding
volute passage terminating abruptly against a radial diaphragm. Closely adjoining this
diaphragm there is a contracted aperture or slit through the periphery of the cylinder,
by which the fluid escapes from the volute passage into the casing. From the casing
there is a pipe leading to the engine, so that the fluid can pass thereto and perform
work after having on its way delivered force tending to drive the cylinder within the
casing.
Dated this 28th day of August 1889.

COMPLETE SPECIFICATION.
An Appliance for Utilising Force of Steam or other Fluid on its
way to Work an Engine.
I, RICHARD LEWIS COUSENS, of St. Georges Club, Hanover Square, in the County
of London, Electrical Engineer, do hereby declare the nature of this invention and
in what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
According to this invention the engine shaft is connected to a cylinder which
revolves within a casing.
The working fluid on its way to drive the engine enters the central part of this
cylinder in which cylinder there is formed an expanding volute passage terminating
abruptly against a radial diaphragm.
Closely adjoining this diaphragm there is a contracted aperture or slit through the
periphery of the cylinder by which the fluid escapes from the volute passage into the
casing. From the casing there is a pipe leading to the engine, so that the fluid can
pass thereto and perform work after having on its way delivered force tending to drive
the cylinder within the casing.
Figure 1 of the accompanying drawings is a plan partly in section shewing the
appliance, according to this invention, in combination with a reciprocating steam
engine Fig. 2 is a transverse section of the cylinder and casing constituting the
appliance.
The steam supply pipe A which may be provided with a shut off valve a and
governing valve a', is in line with the engine shaft B.
Concentric with the shaft is a stationary casing C within which is free to revolve
the cylinder D having formed in it an expanding volute passage d from the centre
where the steam enters to the diaphragm d', whence there is a contracted passage to
an outlet into the interior of the casing C. From the casing C a steam pipe E leads

page_text: to the slide jacket of the engine F. The cylinder D being fixed on the engine shaft B,
the rotation of the cylinder D, caused by the passage of the steam through it, is
imparted to the shaft.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
In combination with an engine, the appliance herein described for utilising force of
the working fluid on its way to the engine.
