Abstract
A lever operated lock mechanism for a hopper door is provided which is especially suitable for use on railway hopper cars having hinged double doors. Included in the lock mechanism is a hook assembly which is pivotally mounted on a housing secured to the door frame or slope sheet of the hopper. A keeper assembly is attached to the spreader bar joining the double doors for engaging the hook assembly, this engagement being at either of two saddle formations or notches, the first or catch saddle formation being engaged when the lock mechanism is in a catch position, and the second or closed saddle formation being engaged when the lock mechanism is in a fully closed position. Movement between the catch position and the fully closed position is greatly facilitated by fulcrum means for receiving a lever bar by which a workman can readily close the hopper doors. Pivotally mounted to the mechanism is a locking latch for abutting engagement between the housing and the hook assembly to thereby wedgingly lock the lock mechanism in its fully closed position.
