12,330. Beech, J. May 31. Combined steam and gas engines ; starting engines. -Double-acting internal-combustion engines working on a two-stroke cycle may be arranged to work in combination with stationary, marine, motor car, or locomotive steam engines. Figs. 1 and 2 show one of a pair of internal-combustion engines applied outside the framing of a locomotive. Steam from the inside cylinders is passed through the jackets 5 of the outside cylinders 1, and afterwards flushes the latter by passing through ports 16 controlled by the cylindrical slide valve 15, non- return valve 17, Fig. 5, and a passage (not shown) leading to the inwardly-opening valve 19, through which a current of air is drawn for subsequent combustion by the inrushing steam. The liquid or gaseous fuel supply to the cylinder is controlled by a piston valve 10, operated by steam from the cylinder jacket 5, which regulates the opening of a port in the valve-chest 7 leading to an oil valve 11 of similar construction to the valve 15, Fig. 2. The valve 11 controls ports which open into passages leading to the valves 19, Fig. 2. Non- return valves 12 are shown in Fig. 5 controlling the passages in the valve-chest leading from the valves 10, 11. The valves 11, 15 are operated by the piston crosshead through rods 28, 25, 23, Fig. 1, and the rod 24, Fig. 2. Valves 20, 21 control the supply of steam to the jackets 5. When starting, the outside cylinders may be supplied with jacket steam, the oil supply being cut off by closing the valve 8 by the levers shown in Fig. 1. When the engine is working as a steam engine, the valve 15 is reversed by raising the end of the lever 24, in the slide block 26, by a lever 34 connected to the bell crank 35. The engine exhaust port 4, Fig. 2, is controlled by the piston.
