Claims.—(1.) In a rotary steam-engine, the combination of a high-pressure cylinder adapted to receive live steam; a low-pressure cylinder adapted to receive the exhaust steam from the high-pressure cylinder; an intermediate steam-chest or chamber; and a conduit connecting the high- and low-pressure cylinders and passing through the steam-chest or chamber, whereby the exhaust steam is subjected to the heat of the live steam on its passage from one to the other cylinder. (2.) A compound rotary engine comprising a plurality of cylinders in axial alignment; a plurality of chambers likewise in axial alignment, each of circular form, and having the circle of its inner wall arranged to cut that of the cylinder with which it is formed; a shaft passing axially through the cylinders; a second shaft parallel with the first, passing axially through the supplemental chambers; gears carried by said shafts, one in each cylinder and one in each chamber, and arranged to mesh in pairs; pistons carried one by each gear within the cylinders; a port for the admission of fluid to the first of said cylinders; an eduction-port for the exit of said fluid from said cylinder; a conduit or passage connecting the exhaust-port with an inlet-port of a succeeding cylinder; an exhaust-port for such succeeding cylinder; and a valve adapted alternately to admit and to cut off steam from the inlet-port of the first cylinder of the series. (3.) In a compound rotary engine, a plurality of cylinders each provided with a revolving piston; an inlet-port for the first cylinder of the series; an eduction-port for said cylinder; passages connecting the eduction-port of the first cylinder with an induction-port of a succeeding cylinder; a cut-off valve for permitting and controlling the induction of steam to said first cylinder, said valve having a fixed axis, but capable of rocking or turning about said axis; and means substantially such as described for controlling the movements of the valve, whereby steam may be cut off from the first cylinder at a predetermined point in the stroke or revolution of its piston, substantially as described. (4.) In a compound rotary engine, the combination of a high-pressure cylinder; a low-pressure cylinder; and an intermediate steam-chest having walls in common and co-extensive with the adjacent cylinders, whereby the live steam within the chest is caused to maintain a relatively high temperature in the high- and low-pressure cylinders. (5.) In combination with high-pressure cylinder A and chamber B in communication therewith, shafts C, D, provided with gears E, F, the former carrying a piston G; steam-chest or chamber J; a cut-off valve H serving to open and close an induction-port between the steam-chest and the cylinder A; a reversing-valve I interposed between the cut-off valve H and the cylinder A, said valve I being provided with ports d and e within the casting of cylinder A adapted to register with ports b and c thereof, and further provided with ports t and v and t¹ and v¹; a low-pressure cylinder casting M provided with ports s, s¹, w, w¹, with which under different adjustments the ports t and v and the ports t¹, v¹, may be made to register alternately; shafts C and D extending axially through the cylinders and the supplemental chambers A and M and B and N; gears E, F, within the chamber A, gear E being provided with a piston G and gear F with a recess G¹; gears O and P carried by the shafts C and D within the cylinder M and chamber N, gear O being provided with piston Q and gear P with recess or cavity Q¹; valve L provided with ports o, p, q, adapted
to register under different adjustment with ports i, j, k and m in a casing surrounding the valve; a partition S separating the low-pressure cylinder casting into two spaces or chambers outside of the cylinder and its supplemental chamber; inlet-ports h and y affording communication from the interior of the steam-chest to the interior of the valve L under a certain adjustment of the valve; and a valve T controlling the port y, all substantially as set forth. (6.) In combination with cylinder A, provided with an inlet-port c and an outlet-port f; a rotary member E contained within the cylinder A, and provided with a revolving piston G; a rotary abutment adapted to co-operate with the rotary member E and piston G; a second cylinder M provided with a rotary member O, having piston Q, and co-acting rotary abutment P; a tubular valve controlling the exhaust-port f of the first cylinder, and extending thence to a steam-passage of the second cylinder; and an inlet-port for said second cylinder communicating with said valve through the intermediate steam-passage, all substantially as shown and described. (7.) In a rotary engine, the combination of a cylinder A and supplemental chamber B, the former provided with a channel or depression z; an inlet-port c; an exhaust-port f; rotary gears E, F, arranged within the cylinder A and chamber B, and concentric with said chambers, the gear E being provided with a piston G, and the gear F formed with a recess G¹; and means for admitting steam to and cutting off the steam-supply of cylinder A. (8.) In a compound rotary engine, the combination of cylinders A and M and intermediate steam-chest J; gears E, F, and O, P, arranged within the respective cylinders and their supplemental chambers, and provided respectively with pistons G and Q and cavities G¹ and Q¹; reversing-valves I and L; and cut-off valves H and T adapted to control the several induction and eduction ports, substantially as described and shown. (9.) In a rotary compound engine, a low-pressure cylinder provided with induction and eduction ports; and a valve controlling said ports and adapted when set in one position to admit steam into the cylinder from the high-pressure cylinder, and when adjusted to another position to cut off communication with the high-pressure cylinder and to open communication with the steam-chest or supply, and thereby to admit live steam to the low-pressure cylinder to reverse its action.
