Improvements in or relating to Gas, Oil, and like Engines

13,314. Redrup, C. B., and Richards, W. A. June 13. Gas engines.-Figs. 1 and 3 show a two-cylinder, four-stroke-cycle, revolving-cylinder engine in which the charge is drawn into the enclosed crank chamber c through a hollow crank shaft, and compressed by the pistons on their respective in-strokes. The compressed charges are forced into the reservoir q through the non-return valve q , and enter the cylinders a, b through the curved pipes r. The inlet and exhaust valves are operated by the cam k in the ordinary way. An exhaust-silencer t is connected to and rotates with the engine framing together with the reservoir q. If preferred, a separate compression pump may be used, or air compressed by the pump may be passed through the carburetter (not shown). The above method of compressing the charge in motor-road-vehicle and cycle engines may also be applied to two-strokecycle internal-combustion engines.
