(10.) In combination with a steam-cylinder, a revolving piston arranged therein, a rotary abutment having a recess I to receive said piston, an induction-port located in proximity to the rotary abutment, a valve controlling said induction-port, and a channel or passage formed in a wall of the cylinder and extending from a point in proximity to the induction-port to a point distant therefrom, whereby steam entering the piston-receiving recess of the rotary abutment is permitted to pass from said recess into the main steam-space of the cylinder, and to expand therein after the steam-induction port is closed. (11.) In combination with cylinder B, shafts D, E, gears F, G, the latter provided with recess I, and piston H, passage-way or channel n serving to maintain communication between the recess I and the steam-space of the cylinder during a portion of the revolution of the gear G, substantially as and

for the purpose set forth. (12.) In combination with the cylinder and revolving piston of an engine of the character described, a packing-strip for said piston comprising two angular members Z, each extending radially along one side or end of the piston and partially across the peripheral face thereof parallel with the axis of revolution. (13.) In an engine of the character described, and in combination with the piston H thereof, having grooves or recesses to receive it, a packing-strip Z comprising two angular sections each extending across one side or end of the piston and partly across its peripheral face, and springs acting upon the respective sections and serving to move them outward both radial to and in the direction of the axis of revolution of the piston. (14.) In an engine of the character described, the combination with a steam-cylinder, of a piston H, packing-strips provided with studs i, and springs j bearing against the studs and serving to move the strips outward obliquely to the axis about which the piston travels. (15.) In combination with a cylinder and a steam-chest, each provided with a seat or chamber concentric with the cylinder, a shaft passing axially through the cylinder, and rollers interposed between said shaft and the walls of said seats or chambers, substantially as described and shown. (16.)
