The exhaust lead by this device increases asthe cut-off is shortened. This secures a maximum powerwhile starting and a sufficient late compression to preventthe terminal pressure from exceeding the initial pressureat high speeds without by-pass or compression valves. The valve gear makes use of the Stephenson link,eccentrics and rocker arm as far as the end of the valve ing about one-eighth inch more lead for the shorter cut-off. The steam chests are fitted with a ten-inch bushing andthe valves have cast iron packing strips which are freeto move and adjust themselves to any irregularities inthe seat, thus reducing the leakage. The illustrations ofthe bushing shows two steam ports in a vertical line }iinch wide. The exhaust port is 1% inches wide an
