OPENING STOP DEVICE FOR RAILWAY FREIGHT CAR DOOR OUTLET GATES

WIPO Patent Application WO/2023/288120

A3

Disclosed is a hopper car gate assembly including a frame configured for attachment to a hopper car body. The frame defines an opening and includes a beam, wherein the beam has a slot formed therein. A stop plate is removably attached to the beam to selectively obstruct the slot. The assembly has a door supported by the frame. A stop block is attached to the door, wherein the stop block is located on the door such that when the door is inserted into the frame the stop block is aligned with the slot. With the stop plate attached to the beam, the stop block engages with the stop plate to define an open position and prevent further movement of the door in the open direction. With the stop plate detached from the beam, the stop block passes through the slot to allow removal of the door from the frame.
