PROVISIONAL SPECIFICATION.
Improvements in Rotary Steam Engines.
MATTHEW HENRY SKELT, 32 Melbourne Terrace Queen's Road, Lowestoft,
Suffolk, Mechanical Engineer. I do hereby declare the nature of this invention
to be us follows:-
Which consists of a new and novel design of Rotary Steam Engines and the
application of the expansive force of steam thereto. It consists of an arrange-
ment of a Metal Outer Casing A, of three or more Segments of Circles with an
Inner Cylinder D. revolving in contact with the inner terminal points B. of the
above mentioned Segments of Circles or Outer Casing A. The Cylinder D. is
extended at both ends in the form of a Hollow Shaft or Spindle E. the steam
being admitted at one end F. and the Exhaust Outlet G. arranged at the other:
The Cylinder D. is fitted with a novel arrangement of Piston Valves which have
a reciprocating motion and are hollow for the admission of steam to the space I.
between the Inner Cylinder D. and the Outer Casing A. The said Piston
Valves H. when open for the admission of steam are projected against the inner
surface B. of the Outer Casing A. thereby forming a Lever at J. which revolves
with the Inner Cylinder D. The Exhaust is taken thro' an aperture in the
Cylinder D. and discharges through the Hollow Spindle K. and the opening L.
The Outer Casing A. is fitted with top and bottom Covers which are Cone shaped
and arranged with Stuffing Box and Gland C. to receive packing.
This Motor can be used as a Stationary Engine transmitting power from the
revolving Cylinder D. and the extended Hollow Shaft or Spindle K. or as a
Motor Wheel transmitting power through the Outer Casing A. revolving whilst
the Hollow Shaft or Spindle K. and Cylinder D. remains fixed.

Improvements in Rotary Steam Engines.
MATTHEW HENRY SKELT, 32 Melbourne Terrace Queen's Road Lowestoft,
Suffolk, Engineer. I do hereby declare the nature of this invention and in what
30 manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
A Mechanical Device consisting f combination of
A

page_text: to perform work by the expansive force of steam in the form of a Rotary Steam
Engine.
Referring to the drawings filed with my Provisional Specification
A Metal Outer Casing A. in the form of three or more Segments of Circles
with Circular Flanges on both sides to affix Covers thereto.
An Inner Cylinder D. revolving in contact with the inner terminal points B.
of the above mentioned Segments of Circles or Outer Casing A.
The Cylinder D. is extended at both ends in the form of a Hollow Shaft or
Spindle E. the Steam being admitted at one end F. and the Exhaust Outlet G.
arranged at the other end and is stopped or plugged in or near the centre.
It is also fitted with an arrangement of Piston Valves H. & J. either cir-
cular or rectangular which have a reciprocating motion and are hollow or tubular
for the admission of steam to the space I. between the Inner Cylinder D. and
the Outer Casing A.
'
The Steam upon being admitted through the Hollow Spindle F. passes into the
Piston Valves projecting them against the inner circumference of the Outer
Casing A. thence through the opening in the said Piston Valves into the space I.
between the Inner Cylinder D. & the Outer Casing A. causing the Inner Cylin-
der 1. to revolve & the Piston Valves to move in & out, open & close as they
revolve with the Inner Cylinder D. the pressure of steam causing them to remain'
projected against the Inner Surface of the Outer Casing A.
The Steam is automatically cut off at each stroke of the Piston Valves.
The Exhaust is taken through an opening in the Cylinder D. and discharges
through the Hollow Spindle K. & the opening L. or if preferred is allowed to
escape through the Hollow Shaft or Spindle at E.
The Outer Casing A. is fitted with top & bottom Covers arranged with Stuffing
Box & Gland C. to receive packing.
This Motor is used as a Stationary Engine transmitting Power by the revolving
Inner Cylinder D. and Hollow Shaft or Spindle K. & E. the Outer Casing A.
is securely fixed to Bed Plate & Stand.
Or as a Motor Wheel transmitting power by the Outer Casing A. revolving
the Hollow Shaft or Spindle K. & E. is securely fixed to Bed Plate by suitable
Brackets.
Having now particularly described and ascertained the nature of my said
invention & in what manner the same is to be performed I declare that what. I
claim is:-
"
1. To utilize the expansive force of Steam to the Mechanical Device or com-
bination hereinbefore, described in the above Specification and the Drawings
left with my Provisional Specification.
2. That the combination of the Outer Casing A. the Inner Cylinder D. and
the Piston Valves do form a distinctly new & novel series of mechanical move-
ments in their application to the purposes of Rotary Steam Engines.
3. The application of the principle of the cutting off of the steam to Rotary
Steam Engines by the Piston Valves herein before described.
4. The Outer Casing A. in the form of three or more Segments of Circles &
Flanges on both sides to affix Covers thereto.
5. The Inner Cylinder D and extended, Hollow Shaft or Spindle E. and Piston
Valves.
FEATURES OF NOVELTY.
The novel features of my invention consist of the application of the expansion
force of Steam by the Automatic Cut-off to Rotary Steam Engines.
The Shape
or design of the Outer Casing A. and the Inner Cylinder D.
The total absence of vibration whilst running at any speed.

page_text: FEATURES OF UTILITY.
That it is light & can be manufactured at low cost that it can be used for every
purpose for which a Steam Motor is required, that owing to the absence of vibra-
tion whilst working it is especially useful for Motor Cars and propelling Road
Vehicles.
