(4.) In a rotary engine such as described, means for making a steam-joint between the periphery of the abutment and the circular wall of the annular chamber in which the piston of the motor revolves, said means consisting of the combination with the said circular wall of a ribbed plate fitting a dovetailed recess therein, and a contact-bar having a groove to receive the rib of said plate, and springs located in holes in the said plate, substantially as specified. (5.) A compound rotary steam-engine comprising, in combination, coaxial annular chambers, a main shaft common to and eccentric with said chambers, discs upon said shaft one for each chamber, a piston upon each of said discs, recessed cylindrical abutments rotatably mounted one in each annular chamber, valves controlling admission and exhaust of steam to and from the annular chambers, with means for rotating said abutments and for actuating said valves from the said main shaft, substantially as specified. (6.) A compound rotary steam-engine comprising a casing, a partition dividing the casing in a plane at right angles to its axis, circular walls projecting towards each other within the casing on each side of the partition, a main shaft axial with said circular walls, a disc secured to the shaft upon one side of the partition, a piston upon the disc, a second disc similarly secured upon the other side of the partition, a piston of larger area thereon, the said pistons rotating in annular chambers bounded by the circular walls and the casing, rotatably mounted abutments one for each annular chamber, means for rotating the abutments, steam-valves controlling admission and exhaust of steam, gear for actuating the steam-valve, and a pipe conducting steam exhausted from one annular chamber for use in the other annular chamber, substantially as set forth. (7.) The combination in a rotary engine of a main shaft, cams thereon set at diverse angles, rocking-levers adapted to be rocked by the cams, blocks slidable in bifurcations of the rocking-levers, pins through the block, suspension-links to which the pins are fixed, arms to which the suspension-links are pivoted, a rocking-spindle to which the arms are secured, a lever secured to the spindle, a valve-spindle, a sleeve fitting the valve-spindle, steam-valves secured to the spindle and sleeve respectively, arms fixed to the spindle and sleeve respectively, pins projecting from the arms, pivoted intermediate levers having eyes for engaging the said pins and the pins of the suspension-links respectively, a reversing-lever, with means for retaining the same in a plurality of positions, a pivoted lever, a rod connecting the reversing-lever to said pivoted lever, and springs connecting the said levers to the rocking-levers, substantially as set forth. (8.) In a rotary engine, means for oscillating a cylindrical steam-valve, comprising, in combination, a main shaft, a cam thereon, a rocking-lever adapted to be rocked by the cam, a block slidable in a bifurcation of the rocking-lever, a pin through the block, a suspension-link carrying said pin, an arm upon which the suspension-link is pivoted, a spindle upon which the steam-valve is secured, an arm fixed upon said spindle, a pin projecting from the arm, a pivoted intermediate lever having eyes for receiving said pin and the pin of the suspension-link respectively, substantially as specified. (9.) In an engine of the type described, reversing-gear comprising a reversing-lever and quadrant, a pivoted lever, a rod connecting the reversing-lever to the pivoted lever, a pivoted rocking-lever, and springs connecting the said levers to the rocking-lever, substantially as set forth.
