George Corliss received US Patent 6162 for his valve gear on March 10, 1849, a more efficient type of steam engine which ran more efficiently on less fuel. The patent covered the use of a wrist-plate to convey the valve motion from a single eccentric to the four valves of the engine, as well as the use of trip valves with variable cutoff under governor control that were associated with Corliss Engines.
The collection contains a manuscript about George Corliss by William Sawyer, 1988, "Corliss--Man and Mchine"; with photocopies of drawings and illustrations.
