Hancock, General Superintendent of Moti by-pass valve consists of a plate whichrests on a horizontal seat, and nor-mally covers openings leading to tlielive steam ports. When the throttleis open, the plate is held down byboiler pressure which acts on its uppersurface. Excessive pressure within thecylinders will cause the plate to liftfrom its seat, thus opening communica-tion between the two live steam center lines of the steam chestsare placed 4^^ ins. outside the centerlines of the cylinders, thus making pos-sible a simple arrangement of Wals-chaerts valve gear with all movingparts in practically the same verticalplane. As the engine is equipped withinside admission valves, the eccentriccranks follow the pins. The cranksare of cast steel, and are secured tothe main pins by a tapered fit andthrough bolt.
