Abstract
138,700. Lechmere, W. F. Feb. 7, 1919. Valves, valve-gear.-Combustible mixture is compressed in a crank chamber 5 having transfer passages 14 which open into the combustion space through ports 15 located below air-admission ports 12 communicating with an annular chamber 9 formed in the upper portion of the crank case. Scavenging-air is delivered to the chamber 12 by a pump 1. The exhaust ports 17 are controlled by a reciprocating sleeve valve 16 actuated by a pair of levers driven from a grooved cam on a shaft connected to the crank-shaft by two-to-one toothed gear.
