CORLISS VALVE GEAR. In thisdesign, B is the bell crank, which carries thehook H mounted on a short shaft, on theother end of which is the trip lever (not shown),which engages with the knock-off cam C, oper-ated by the governor rod. K is the drop leverwith dashpot connection. The cam lever C,controlled by the governor, limits the time ofrelease of the hook H. 189. Shows the position of the parts at themoment of release. 90 STEAM POWER 190. CORLISS VALVE GEAR. Thisdesign consists principally of a curved bellcrank, B, carrying the grab hook D mountedon a short shaft having an arm at the otherend. The trip lever d rides on the knock-offcam A, the position of which is controlled bythe governor, as usual. When the bell crankreaches the position shown in the upper sketch,the trip lever is thrown outward, releasing thedrop lever, the point of release being governedby the position of the knock-off cam. 19 T. Shows the position of the parts at themoment of release. 192. CORLISS VALVE GEAR. A is a bell-crank lever mountedloosely on the valve stem or on a projection of the bonnet, and carries the grab hook H at one end and is connectedto the wrist plate by an adjustable connectingrod, from which it receives its motion. Thehook H is normally pressed inward by thespring S so that the longer arm of the hookis always held firmly against the knock-offcam C, which is placed next to the bell crankand is connected to the governor by
