JAMES WOODLEY, Engineer, 31, Bradley Street, Roath, Cardiff, in the County
of Glamorgan, and ABRAHAM SHIBKO, Gentleman, 231, Newport Road, Roath,
Cardiff, in the County of Glamorgan, do hereby declare the nature of this in-
vention to be as follows: :-
Our Invention consists of two round cheaks of Metal with a hole through the
centers, the foresaid cheaks are fitted together through the center and hollowed
out for the purpose of receiving a piston we then pass a driving chaft through
the center hole of the foresaid cheaks and connect a disc to the said chaft. The
disc then is provided with a suitable catch for the purpose of connecting the disc,
to the foresaid piston. We hereafter provide a suitable Slide Valve for the purpose
of letting in Steam, Gas, and the like, and also for reversing purposes, We use the
said Slide Valve cross ways for the purpose of turning in steam & Gases at the
right side of the piston required.

An Engine Driven by Steam, Gas, Petroleum, and the like.
We, JAMES WOODLEY, Engineer, and ABRAHAM SHIBKO, Pawnbroker, both of
231, Newport Road, Roath, Cardiff, 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 engine driven by steam, gas, petroleum, and the
like, and has for object to construct and provide such an engine which shall be
effective in action, simple in construction and easy of manipulation, and econo-
mical in working.
The essential features of this our invention are an annular cylinder or piston
race provided with inlet and exhaust passages controlled by a suitable valve so
that either passage as may be required may be utilized as inlet or exhaust in
accordance with the direction it is intended to run the engine. A slide crosses
the piston race between the inlet and exhaust passages in such manner as to
direct the flow of steam or other power upon the face of the piston and form a
cylinder end during each stroke. This slide by suitable mechanism is withdrawn

page_text: from the piston race at each revolution as the piston passes and is immediately
brought into position again after the piston has so passed.
And in order that this our invention may be fully understood and readily carried
into effect we will describe same with reference to the accompanying drawings
and the letters and figures of reference marked thereon, that is to say:
Fig. 1 is an internal elevational view of one half of the annular cylinder or piston
race suitable for a cylindrical piston.
Fig. 2 is a similar view of the other half of cylinder with piston in position.
Fig. 3 is an external elevational view of the same half of cylinder as shewn in
Fig. 1,
And Fig. 4 is an external view of the half cylinder shewn in Fig. 2.
Fig. 5 is an end elevational view of the engine complete..
Fig. 6'is a plan of same.
Agai
Fig. 7 is a sectional plan of the engine through line AB Fig. 5
Fig. 8 is a sectional elevation of each half of the cylinder (separated) adapted
for a cylindrical piston.
Fig. 9 is a similar view of the cylinder adapted for a square piston.
Fig. 10 is an end view of a cylindrical piston and disc attachment to main
shaft,
Fig. 11 is a face view of the piston and disc, and
Fig. 12 is a diagram view illustrating the action of slide.
Figs. 13 and 14 respectively in side view and sectional; plan illustrate how the
slide may be adapted as steam-inlet and exhaust.
Similar letters of reference indicate like parts wherever occurring throughout
all the figures.
a and represent the two halves of the cylinder of an engine. constructed in
accordance with this invention.
This cylinder a b is so shaped as, when bolted together to form an annular
piston race c. This piston race c may be square in cross section as illustrated
in Fig. 9 of the drawings, in which case the piston race c is formed in one half (b)
of the cylinder, the other half (a) forming a cover or side to the piston race.
Or
said piston race may be circular in cross section as illustrated in the other figures
when each half of the cylinder will carry one half of the piston race. d d' are the
inlet and exhaust passages and ee represents a valve operated by a lever e¹ and
capable of controlling these passages in such manner that either passage may be
utilized as inlet or exhaust according to the direction it is intended to run the
engine. For instance with the valve and lever as shewn in full lines in the
drawings, the port d will be the inlet and d the outlet or exhaust. The steam or
other fluid pressure flowing from main pipe f through the valve e enters the
cylinder through inlet d, and after performing the functions passes therefrom
through the exhaust d. But with the lever and valve pulled over to the piston
shewn in dotted lines Fig. 3 it will be at once apparent that the direction of the
steam or other power used is reversed.
g (Figs. 2, 7, 10 and 11,) is the piston, which may be circular as shewn, or
square, or other suitable shape in cross section. This piston is carried in brackets h
upon a disc i fixed to the main shaft k passing centrally through the cylinder a b.
The central portions of the cylinder faces where they meet are shaped (see pai-
ticularly a Figs. 1, 2, 7, 8, and 9) so as to receive this disc i. A circular slot a³
Fig. 1 may be cut in the surface of the central portion aforesaid of cylinder à for
the reception of a packing ring, and a similar packing slot may be made in the
cylinder half b.
The piston 9 may be also grooved around its periphery for a packing ring g',
See Figs. 2 and 11.
Working between the inlet and outlet orifices d¹ there is a slide 7 which
crosses the piston race and forms a cylinder end directing the steam or the like
upon the piston and which by a cam and lever or other suitable mechanism is
withdrawn from the piston race at each revolution to allow the piston to pass.

page_text: A convenient manner of arranging this slide is as illustrated particularly in
Figs. 5, 6, 7, and 12. m is a casing carried upon the cylinder half b within which
the slide is capable of reciprocating. A pin upon the slide 1 (See
Figs. 4, 5, 6, 7, and 12,) protrudes through a suitably shaped slot m¹ (Fig. 5) in
the side of casing m and is connected to the slotted end of a lever n pivotted at
its lower end n¹ to a bracket n2 upon the cylinder b.
A roller o carried upon this lever n travels in the cam groove p on roller
fitted upon main shaft k. As the shaft revolves so is the lever n actuated and the
slide caused to cross the piston race or be withdrawn therefrom. Other means for
automatically operating the slide may however be employed if found desirable
or convenient.
In Figs. 13 and 14 we have illustrated a method of combining the inlet and
exhaust with the slide and casing m.
In this arrangement the ports are formed in the casing m and hollows or
recesses q are formed upon each side of the slide 1. When the slide 7 is in position
across the piston race the steam or other power employed issuing through one of
the ports dd passes by way of the hollow or recess q upon that side of the slide
into the cylinder and drives the piston. It then exhausts through the opposite
hollow or recess and port and when each revolution is completed the slide is with-
drawn from the piston race and the pressure is shut off until the ports are again
opened by the slide entering the piston race. Any suitable slide or other valve,
with or without expansion gear, inay be employed for controlling or regulating
the passage of the steam or other power to the cylinder, the single type of valve e
shewn being merely given as an example.
Having now particularly described and ascertained the nature of our said in-
vention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. The engine driven by steam, gas, petroleum, and the like substantially as
herein before described and shewn in the accompanying drawings.
2. The construction and arrangement of annular cylinder or piston race and
piston working therein, said piston being attached to a disc fixed upon the main
shaft within the cylinder in the manner hereinbefore described, in combination
with a slide worked by a cam from main shaft or otherwise directing the flow of
the steam or other power employed upon the face of the piston substantially as
hereinbefore set forth.
3. The slide crossing the piston race and actuated from the main shaft by cam
or otherwise, substantially as and for the purposes herein before described and
shewn.
4. The cylinder ab, with annular piston race e inlet and exhaust dd', control-
ling valve ee or its equivalent; piston g, brackets h, disc i, shaft k, slide 1, pin l,
slide casing m slotted 'as at ml, pivotted lever, roller o, and camp, or equivalent
mechanism, constructed, combined, arranged, and operating substantially as and
for the purposes herein set forth.
