ABSTRACT:
The side discharge doors of a railway hopper car are maintained in a closed and locked position by a rotatable latch element which is engaged by a stop and lock member. The stop and lock member is connected to a linkage rigging arrangement which is moved by a ground actuated operating and tripping mechanism. The tripping mechanism includes a cam actuated arm which by linkage means transmits vertical movement to horizontal movement of the linkage rigging which actuates the latch and locking members of the doors.
