PROVISIONAL SPECIFICATION.
An Improved Rotary Engine, applicable also as a Pump.
We, ERNEST JOHN CLUBBE and ALFRED WILLIAM SOUTHEY, both of 16, Elm
Street, Gray's Inn Road, in the County of Middlesex, Electrical Engineers, do hereby
declare the nature of this invention to be as follows:-
This invention relates to an improved rotary engine applicable also as a pump.
The engine or pump is of the annular chamber type and the characteristic feature
of the invention is that the abutinents are formed by an annular disc which when the
engine or pump is at work is revolved continuously in a plane at an oblique angle to
the plane of revolution of the pistons, the abutment disc intersecting the cylinder
diametrically. The abutment disc is apertured to give passage to the pistons, its
revolution being so timed with reference to that of the pistons, and the form of the
apertures being such, having regard to the continuous rotation of the pistons and disc
and to the obliquity of their rotation in intersecting planes, that the apertures in the
disc will always be presented in the path of the pistons at the proper moment and will
give free passage thereto whilst the opening and closing of the passages is effected in
the shortest possible time. The pistons project radially from a central spherical boss
on the main shaft working in corresponding spherical bearings in the cylinder covers
which are preferably coned radially or nearly so to the centre of motion, the pistons
being of corresponding form. The abutment disc fits by suitable packings around the
spherical boss and is enclosed in a casing in which it works upon bearing balls
running in grooves between the adjacent faces of the disc, and its casing, and it is
driven from the main shaft through bevel gear and an intermediate shaft carrying
pinion gearing directly with the toothed periphery of the abutment disc.
a
Suitable induction and eduction ports are provided in the cylinder in proper relation
to the plane of intersection of the abutment disc and these ports are controlled by
rotary or other valves actuated from the main shaft, provision being made for variable
expansion in any suitable manner.

An Improved Rotary Engine, applicable also as a Pump.
We ERNEST JOHN CLUBBE and ALFRED WILLIAM SOUTHEY, both of 16 Elm Street,
Gray's Inn Road, in the County of Middlesex, Electrical Engineers 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 an improved rotary engine applicable also as a pump and
will be described with reference to the accompanying drawings forming part of this
specification wherein Figure 1 is a section of the engine taken in the plane of the
main and disc-driving shafts. Figure 2 is a central transverse section through the
cylinder in a plane perpendicular to the shaft. Figure 3 is a face view of the abutment

page_text: disc and driving gear, the cover plate of the casing being removed the same letters of
reference indicating the same parts in all the figures.
The engine is of the annular chamber type and comprises a cylinder A, two
pistons BB attached to a shaft C, and an abutment disc D revolving in a casing E,
the characteristic feature of the invention being that the abutments for the fluid
pressure are formed by the continuously revolving disc D lying in a plane at an
oblique angle to the plane of revolution of the pistons B, the abutment disc
intersecting the cylinder A diametrically. The abutment disc D has apertures F
passing obliquely through it to give passage to the pistons and its revolution is so
timed with reference to that of the pistons, and the form and obliquity of the
apertures F is such, having regard to the continuous rotation in obliquely intersecting
planes of the pistons B and of the disc D, that the apertures F in the disc will always
be presented in the path of the pistons B at the proper moment so as to give free
passage to the pistons whilst the opening and closing of these passages is effected in
the shortest possible time.
The pistons B project radially from a central spherical boss B' on the main shaft C,
the boss working in corresponding spherical bearings in the covers of the cylinder A
which are preferably coned radially or nearly so to the centre of motion of the
pistons, as shewn in Figure 1, the pistons being of corresponding radial form. The
abutment disc D fits by suitable packings d around the spherical boss B₁ and between
packings d in the covers of the casing E in which it is enclosed and in which it
works upon annular series of bearing balls g situated between the adjacent faces of
the disc and of its casing, the balls running in annular grooves G formed in those
faces. The disc D is driven from the main shaft (through bevel gear H I and an
intermediate shaft J carrying a toothed wheel K enclosed in an offset of the casing E
and gearing directly with the toothed periphery of the abutment disc D, the gearing
being so proportioned that the pistons B and disc D revolve at equal speeds assuming
that the disc has as many apertures F as there are pistons.
Suitable induction and eduction ports L M are provided in the cylinder in proper
relation to the plane of intersection of the abutment disc and the induction and
eduction of the inotive fluid through these ports is controlled by rotary or other valves
(not shewn) actuated from the main shaft C, provision being made for variable
expansion in any suitable manner.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The herein described rotary engine or pump constructed to operate substantially
as specified.
2. In a rotary engine or pump, the combination, with the annular cylinder and with
the piston or pistons revolving therein, of a disc intersecting the cylinder diametrically
and in a plane oblique to the plane of revolution of the pistons, the said disc
acting as an abutment for the fluid pressure and being apertured to give passage
to the pistons and being continuously rotated from the engine shaft as specified.
