  • 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.

  • Patent number: 4213725
    Abstract: A hopper car door locking mechanism includes a rotatable latch member which includes a keeper receiving portion. The latch member also includes a positioning portion providing stops which are engaged by a rotatable locking pawl in the closed position of the hopper car door. The rotatable locking pawl includes a cam device which is pivoted in response to reciprocating movement of a rod having a suitable cam surface. The rod also includes a stop device which with the rotatable latch member provides a second stop which therefore provides for double locking of the door.

  • Patent number: 4207020
    Abstract: An open top railway hopper car is provided with longitudinal center dump discharge openings closed by hinged clam shell type of doors. The doors include an arm and linkage arrangement pivoted to the hopper car structure for continually urging the doors to a closed position. The arm and linkage arrangement is opened by means of side of track cams. Locking for each of the doors is provided by means of a locking pawl engaging stops provided on door brackets which preclude opening of the doors during transport. Opening actuation of the arm and linkage arrangement provides for initial displacement of the locking pawls thereby permitting the doors to continue to their open position.

  • Patent number: 4206710
    Abstract: A modular center filler and center plate may be constructed as a unit away from the car and adapted for connection to the center sill webs of a railway vehicle. The center filler has a thick bottom plate which extends beneath the center sill and has pairs of interconnected longitudinal and transverse sill reinforcing plates arranged in a double I-beam manner. The center plate has longitudinally extending attached skirts, and bevels are provided which allow the car to rock at the bevel lines. Forces transmitted through the center plate at the bevels are absorbed and distributed by the associated longitudinal plates and other bolster and center filler structural elements.

  • Patent number: 4198785
    Abstract: A door seal for an inside compartment of a railway passenger vehicle. A door that moves on rollers laterally into and from a door opening to a stored position in a hollow portion of an adjacent wall. The lower portion of the door is located adjacent a threshold having a movable, flexible seal that moves between a flat position covering a roller track portion of the threshold to a substantially upright position against the bottom of the door when the door is located in a closed position. The seal is constructed of a resilient material and bends to be urged against the lower portion of the door in such a fashion as to seal out noise, debris, light and the like. When the door is open the seal returns to a flat, horizontal position to prevent an accumulation of debris or dirt in the door track which would interfere with movement of the door.

  • Patent number: 4194450
    Abstract: A door operating mechanism for a bottom dump hopper car including a plurality of transversely mounted bottom discharge gates arranged in oppositely opening pairs and operatively connected by compression struts to pendulously mounted vertical levers. The levers are movable divergently outward by linkages connecting them to a lever mounted on a longitudinally extending rotatable actuating shaft. The invention further provides that in the locked position the vertical levers and compression struts be in an overcenter position relative to each pair of associated discharge gates, thereby assuring positive locking of the mechanism.
