Fig. 7 is a detail sectional seated in recesses formed in the cylinderview of the same on the plane indicated by heads, as'shown at 32 and 33 in Fig. 2. the broken lines 7 7 of Fig. 6. Fig. 8 is a de- 34 indicates the exhaust-port at the bottom tail perspective view of the rotary piston and of the cylinder, from which a channel 35 95 shafts when constructed with the shafts proleads outward through the base. There are jecting on both sides of the piston.

40 indicates the steam-pipe, provided with a throttle-valve 4l and leading to a three-way valve 42 at the junction with branch pipes 43 and 44, leading, respectively, to the inletports 36 and 37. The valve 42 is provided with an operating-lever 45, which may be held at any adjustment by a clamp-screw 46, passing through a curved slot 47 in a curved bar 48, secured by standards 49 to the top of the cylinder. By turning the valve 42 steam may be admitted to either of the inlet-ports, according to the direction the engine is to be driven. The steam enters either of the spaces 50 or 5l in the cylinder above the blade, which may be in advance of the ports and forces that blade around until its forward end reaches the exhaust-port, when the steam will be exhausted. Before this takes place the other blade has passed the inlet-port and is being forced around. As the blades rotate they slide in the rotary piston, both ends of the blades always contacting With'the cylinder on account of the elliptic shape. The steam-receiving chambers are continually expanding in size until the exhaust takes place, thus offering the least possible resistance to the movement of the blades.
The engine is non-reacting, reversible, and smooth-running.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
l. In a rotary engine, the combination, with a cylinder, the head of which is perforated above the center and recessed/upon its inner face, concentrically to said perforation, of a shaft projecting through saidfperforation and provided upon its inner endl with a series of sector-shaped sections forming a substantially cup-shaped piston, the sections being at a distance apart and the inner end of the shaft being provided with intersecting grooves to register with the spaces between the sections, reciprocatory blades between the sections and in said grooves, and inlet and exhaust ports in the cylinder. l
