摘要： A railway hopper car (H) has a bottom outlet (B). An outlet assembly (A) is attached to the outlet for lading to be discharged into the outlet. An outlet flange (OF) at the bottom of the hopper defines the lading discharge outlet. A mating flange (F1) is formed on the outlet assembly for attaching the outlet assembly to the railcar. Fasteners (L) are used to mount the outlet assembly to the hopper bottom. A gasket (3) installed between the respective flanges effects a seal between the hopper outlet and outlet assembly. The gasket extends circumferentially about the opening. One of the flanges has a circumferential groove (9) and the gasket has a raised portion (15) extending circumferentially of the gasket and sized to be received in the groove. This arrangement aligns the gasket with the flanges so when the outlet assembly is mounted to the bottom of the hopper, no cavities are formed in the between the hopper outlet and the outlet assembly. Similarly, an end adapter (E1, E2) is attached to the ends of the outlet assembly. A second gasket (5) is used to effect a seal between the adapter and outlet assembly. A groove (23) is formed in an outlet assembly flange (F2) to which an end adapter flange (MF) mates, and the gasket has a raised portion (25) fitting in the groove also align the gasket.

摘要： A hopper is provided having longitudinally spaced tapered end walls and transversely spaced tapered side walls. An opening is provided in one of the end walls and a discharge conduit is attached to the external surface of this end wall. On the internal surface of this end wall a discharge trough is attached. The front surface of the trough is tapered on the same incline as this end wall. Fluidizing membrane assemblies are attached to each of the side walls which are inclined downwardly toward the discharge conduit to facilitate lading flowing into the discharge conduit during unloading. The discharge trough is generally in the form of an inverted V, with the lower edges of the V spaced from the lower hopper wall a distance sufficient to allow air and lading to pass around the trough and into the discharge trough. The lower edges of the V are preferably tapered inwardly and downwardly toward the end wall to increase the velocity of the fluidized lading as it passes into the trough and then into the discharge conduit.

摘要： A pair of longitudinally spaced valve elements are provided in a pneumatic outlet. Each valve element includes a body portion, preferably a segment of a circle, including a body portion edge which seats on a body portion valve seat located adjacent the body portion edge, and a moment portion extending eccentrically away from the body portion, which seats on a moment portion valve seat. Each valve element is movable to a sampling position in which the body portion is spaced from the body portion valve seat and the moment portion is spaced from the moment portion valve seat to allow lading for sampling to flow into the discharge conduit. Each valve element includes a pair of operating shafts extending in opposite directions from the valve element, parallel to the discharge conduit, through opposite end walls of the outlet. Operating handles are attached to the operating shafts outside the end walls of the outlet. The discharge conduit end caps are held in place with a pair of large headed bolts which are pivotably mounted on the discharge conduit and which engage at least a portion of the adjacent end cap. The large headed bolts are attached to vertically extending locking members of generally inverted J shape which are rotatably mounted on a side of the discharge conduit. In accordance with the present invention, the lower locking surface on a pair of diagonally spaced inverted J bolts is spaced from its respective operating handle a distance sufficient that if the end cap on the near or sampling end of the outlet is removed, the operating handle on the sampling end may be rotated sufficiently to move the valve member away from its valve seat a distance sufficient to take a sample of lading, without removing the end cap on the opposite end of the discharge conduit.

摘要： A gravity outlet (10) for discharging lading from a railway car (C). An outlet assembly attached to a discharge opening in the railcar includes an upper end attached to the opening and sidewalls (12a, 12b) and endwalls (14a, 14b) whose bottom portion defines an outlet (D) through which lading flows, by gravity, when discharged from the railcar. An outlet gate (34) positioned beneath the outlet assembly moves relative to the discharge outlet between respective open and closed positions. A latch mechanism (36) includes a latch (50a, 50b) pivotally attached to the gate to latch the gate in its closed position and prevent inadvertent opening of the gate and spillage of lading. A gate operating mechanism (38) includes a rack (40) attached to the gate and a pinion (42) engaging the rack for moving the rack and the gate. A capstan (46) is connected to an operating shaft (44), as is a coupling member (64). Rotation of the capstan by yard personnel effects movement of gate between its open and closed positions. A blocking bar (62) is engaged by the coupling member to lock the gate in its closed position. A lost motion connection between the pinion and the coupling member enables the gate to be unlocked prior to movement of the rack by the pinion, and locked in its closed position subsequent to movement thereto by the rack and pinion. The arrangement produces a desired sequence of gate operations (unlocking, opening, closing, relocking) which occur automatically.

摘要： A gasket for a hopper outlet is disclosed, particularly well-suited for use between the frame of the hopper and the frame of an unloading outlet for a railway hopper car. The gasket has a central metal frame carrying a pair of relatively hard, continuous elastomeric seals along each edge of the frame. Each of the seals has a lip which protrudes upwardly (or downwardly) and outwardly from the body of the gasket so as to be readily compressed upon initially mating with the frames to ensure sealing even if the frames are warped. Such a gasket may be retrofitted to existing outlets.

摘要： An internal water drainage system for an interconnected hollow structural assembly within a railroad pressure discharge hopper car or the like is disclosed. To facilitate water drainage throughout the interconnected hollow structural assembly following hydrostatic pressure testing of the car, water draining passageways are provided in the hollow structural members in an area of juncture between the members, at least along a lowermost extent of each of the hollow structural members. The water drainage passageways are constructed to communicate with a water drain opening provided in the shell of the railroad car, in order to afford gravity flow of water through the hollow structural members and evacuation from the railroad car. A method for hydrostatic pressure testing of a railroad car is also disclosed in which gravity flow evacuation of water through the hollow structural members is achieved by utilizing gravity flow of water throughout. In both the aforementioned assembly and method, water deterioration, corrosion, and the like after hydrostatic pressure testing are substantially minimized or totally eliminated.
