23,065. Sunderland, H. Oct. 23. Exhaust steam, returning to boiler.-In an apparatus for compressing the exhaust steam from an engine and pumping it back into the boiler, the exhaust steam is admitted through the valves b, c into the compression-cylinder a, then passed through the valves e or f into the chests m, and through pipes p into the smaller cylinder h, where it is further compressed, and then passes through valves q to the boiler. The pistons g, i are connected to a rocking shaft so that one moves up when the other moves down, this shaft being connected, by a bell crank lever k, with the crosshead or other working part of the engine. The valves b, c are not opened by the eccentric d until the pressure in the corresponding ends of the cylinder a has fallen to the pressure in the exhaust pipe.
