  • Patent number: 4215515
    Abstract: An operating rod assembly for use with a sliding plug door of a railway freight car. The operating rod extends vertically and it is connected with a manually actuated mechanism. Both the upper and lower ends of the operating rod are connected with adapter rods of each door crank member which move the plug door into and from the door opening. At both the upper and lower ends of the operating rod there is a telescoping connection between the operating rod and the associated crank. The telescoping connection is secured by a fastener which interconnects the operating rod to each crank attached adapter rod. When the door is in the locked position the fastener is in a captured position adjacent the door to prevent disassembly or accidental separation of the rod members during transit.
