Fig. 1 is a view looking at crank side of the engine. The founda-tion is protected from oil and water by a bead which extends aroundthe outer edge of the base and conducts the oil, etc., to a pit under thecrank disk, from which it is drawn out through a pipe and saved forfiltering to be used again.

It will therefore be seen that the valve has two motions; one, aninvariable reciprocating motion, the other a twisting motion, which isinvariable in degree, but variable relative to the reciprocating variation is accomplished by the rolling of the sleeve on theeccentric, whenever the governor weights change their position as a re-sult of a change in speed. The experience of this company with piston valves condemns theiruse in a horizontal position. For, notwithstanding they are perfectlybalanced against steam, their weight produces friction which causeswear, and soon results in leakage. The company will use them in itsvertical compound and triple expansion engines, in which the weight willbe supported by the valve stem in a vertical position, doing away withfriction and consequent wear. The type of valve used in the horizontal engines, consists
