摘要：
An apparatus for pivoting and locking a door on the bottom of a rail hopper car includes a locking mechanism for locking the door when closed and a lever mechanism for pivoting the door between closed and open positions. The locking mechanism and lever mechanism are separate but are operated by a single sliding operating linkage on the bottom of the car.
