发明名称 Cam actuated railway hopper car door operating mechanism
摘要 A door operating mechanism for a bottom dump railway hopper car including a plurality of longitudinally mounted, divergently opening discharge doors held in the closed position by a plurality of longitudinally spaced claw-like latches. Each pair of transversely opposite latches includes operating rods connecting each latch to a bell-crank positioned beneath the longitudinal hood of the car. The bell-cranks are operatively connected to a longitudinally disposed tension rod, which includes linkages at either end for actuation of the mechanism by trackside mounted cams.
