Abstract

See full text

A railway car having an end opening includes a swingable folding door assembly provided with a keeper mechanism carried by the door assembly and the adjacent side wall of the railway car. As the panels of the door assembly are folded from a flat, closed position overlying the car end opening to a collapsed, open position disposed substantially longitudinally extended away from the end of the car side wall, a guide rod carried by the door assembly is arcuately displaced to simultaneously horizontally shift a vertical locking pin to a position overlying an aperture in a lock plate whereupon gravity concurrently drops the connected rod and pin to secure the open door assembly in a fixed position.
