Closure mechanism for bottom dump hopper cars

摘要

A side of track closure mechanism is provided for engaging and exerting an inwardly directed lateral thrust against bottom dump doors of a hopper car for hingedly moving the doors inwardly to a closed position. The actuating mechanism includes a rotating arm having actuating apparatus at one end which when placed in an index position is adapted to engage the doors of bottom dump hopper cars as they move along a track adjacent to which the closure mechanism is positioned.
