White and Middleton

White and Middleton engines were used both in the original Victorian era Argonaut-class submarines of Simon Lake[5] and in the Protector-class submarines[6] built by the Lake Torpedo Boat Company of Bridgeport, Connecticut and sold to the German, Austro-Hungarian, and Russian Imperial Navies during the decade preceding World War I.

[7] A White and Middleton engine powered the electrical generator for Vanderbilt's Biltmore Estate in Asheville, North Carolina.

[14] An engine of the ordinary four-cycle type, for gas or gasoline, is made by the White & Middleton Company, Baltimore, in sizes from 4 to 50 B.H.P.

Ports are also uncovered by the piston, through which part of the exhaust products escape; the remainder are discharged at the end of the stroke through a valve worked by a rod and levers from the crank shaft, through a slide and cam.

If the engine is driven with gasoline a small oil pump is substituted for the gas valve-rod, and is controlled on the "hit-and-miss " principle by the governor.
