ABSTRACT:
A 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 which is mounted on an outside hopper sheet and which is pivotable for engaging extensions of a spreader bar joining the double doors. The hook, being mounted through a slot therein, in addition to being pivotal is also slidable through a limited slaping path that is generally parallel to the floor of the hopper, such slidable action enabling the doors to be held at either a "catch" position or a fully closed position. The lock mechanism positively positions the doors with opening and closing operations. An especially secure lock, one which maintains door closure even when the railway car is rotated is attained when a latch having a spring-like projection holds each hook and thus the hopper doors in their fully closed positions.
