CA 2213913

A discharge gate assembly for a railway hopper car that satisfies the new AAR requirements and specifications and includes a frame defining a generally rectangular discharge opening with a gate slidably mounted on the frame for endwise horizontal movement between opened and closed positions. An operating shaft assembly is supported on opposite frame extensions for rotational movement about a fixed axis. The operating shaft assembly is operably coupled to the gate. A lock assembly is operably coupled to the operating shaft assembly and includes a vertically displacable stop member mounted for vertical and rotational movement about a fixed axis extending above the path of movement of the gate and in fore-and-aft relationship relative to an edge of the gate. When the gate is in its closed position, the stop member extends downwardly and into engagement with the gate edge to positively prevent the gate from substantial movement toward an open position. A drive mechanism is disposed adjacent the frame extensions for positively displacing the stop member from the path of travel of the gate in timed relation relative to movement of the gate toward an open position.
