Fig. 12, is an end view or the same.

Similar letters refer to similar parts throughout the several views, and in the
following description "steam means steam, water, or other suitable fluid for giving
motive power to the engine.

is the foundation plate on which the several parts are carried and which is
fitted (by preference) with guides a¹, a'..
bb, are bearings for carrying the driving shaft s.
cc, are brackets fitted accurately in the guides a', and having faces a a,
truly turned and fitted so that they may be exactly parallel with one another.
These brackets are held together accurately at the correct distance by bolts and
nuts c c.
d, is a disc wheel keyed firmly to the shaft s, and fitted with facing rings; in
each of these facing rings is formed a groove », (see Figs. 6, 7 & 8) which
receives the steam and forms the working groove or cylinder of the machine.
ff, &c., are slides or valves fitting into recesses, formed in the rings r, and
dividing the same into segments. These slides are capable of being pushed back into
recesses, so as to leave the groove, free when desired; they are held up against
the face a, by the springs g.
hh, are blocks having attached to them bolts h', by means of which they are
firmly bolted to the brackets cc, and at their inner ends fitting the groover, so
as to completely fill it but at the same time allowing the disc d, and its groove r',
to revolve freely. These blocks hh, are by preference fitted with removable faces
or shields, which can be easily removed and renewed; moreover if these shields
are left with a little play on the top and bottom of the block, the shaft s, with
disc d, may slightly fall without making the groove, bear too heavily on the
said block.
S, are the steam pipes to supply the groove, with steam.

the axhaust nines for removal of the steam.

page_text: , is a space in the bracket, forming a small steam and exhaust chest on either
side of the stationary block h.
h2h³, are wings or cams forming inclined,planes leading up to the block h, for a
purpose to be hereinafter described.
The action of the machine is as follows:-
The disc wheel d, with its axle or shafts, revolves freely and truly in the
bearings, between the brackets cc, the steam being admitted by the pipes S S,
equally and on opposite sides into the groover, the disc d, is in equilibrium and
thus the pressure and wear against the faces ², is reduced to a minimum. The
stationary block 4, divides the steam entrance from the exhaust exit so that when
live steam is entering on one side of the said block exhaust steam is leaving by the
other side of the same, the steam having entered between the stationary block h,
and the slide or valve, the pressure against the valve causes the disc with its
shafts, to revolve by the pressure of the steam on the surface of the valve f
exposed to the steam in the groove; when the said valve reaches the wings or
cams. the valve f, is slided back into the recess f", by means of the said wings or
cams thus leaving the steam between the two valves, free to pass out of the.
exhaust E, whilst a fresh charge of steam is pressing against the slide in front of
the steam pipe S, and thus every division of the groove, of the disc d, formed by
the valves is alternately filled and emptied causing the disc d, and shafts, to revolve
and give motive power.
Several slides or valves are shewn on the drawings but it is evident that so long
as the part of the groove exposed to the exhaust is separated from that exposed to
the steam the number of slides is immaterial; but the more slides there are the less
liability to leakage and waste of steam.
It will be seen from the drawings that there is an exhaust pipe and steam pipe
situated on either side of the stationary block h, by which the engine can be
worked in either direction; if the exhaust pipe on the right and the steam pipe on
the left are closed the machine will revolve to the right and rice versa if the exhaust
pipe on the left and the steam pipe on the right are closed the machine will
revolve to the left; and thus a simple reversing gear is obtained. If, however,
the engine is not required to be reversible one steam pipe and one exhaust
pipe only need be provided on either side of the block , and thus simplify the
machine.
It will also be understood that instead of one groove »¹, two or even a series of
concentric grooves with their sliding valves and blocks may be made use of to actuate
the machine thus giving increased power, or in the case of two concentric grooves
one may be made to actuate the machine in one direction and the other to reverse
it giving another form of reversible engine.
I am aware that prior to my invention rotary engines have been operated in
various ways; I do not therefore claim such a machine broadly,
Having now described and particularly ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is,
1. In a rotary engine the combination of the revolving disc d having a working
groove, and sliding valves, with a stationary block, and guide wings or
cams, all substantially as set forth.
2. In a rotary engine such as described herein the double steam and exhaust pipes
combined with block h, having guide wings or cams ³, for the purpose of reversing,
all substantially as set forth.
3. In a rotary engine such as described herein the use of concentric grooves
substantially as set forth.
