摘要： A railway car hopper having downwardly and inwardly inclined side walls and end walls defining a rectangular hopper discharge opening is provided with a downwardly extending discharge chute. A gate for opening and closing the hopper discharge opening is supported for reciprocable movement by the discharge chute. The discharge chute has a pair of integral cold formed steel members defining the side walls and integral cold formed steel members defining the end walls. The discharge chute side walls each have an upper inwardly and downwardly directed flange. The top surfaces of the flanges each engage an outside surface of one of the downwardly and inwardly inclined side walls of the hopper. The bottom surfaces of the flanges each define a gate receiving and supporting elongated groove with a remaining portion of its respective integral cold formed member. The grooves each include a downwardly and inwardly directed surface for slidingly and sealingly supporting upwardly and outwardly turned edges of the gate. One of the discharge chute end walls also has an upper inwardly and downwardly directed flange with a top surface engaging an outside surface of one of the downwardly and inwardly inclined end walls of the hopper. The other integral cold formed end wall of the discharge chute has an upper gate supporting flange member.

摘要： A multi-deck rail car having an interior cavity and an end opening for loading and unloading lading is provided with a pair of door assemblies, each of which includes a plurality of panels. Each door assembly is pivotally movable for closing at least a portion of the end opening. Double vertical pivots mount each of the door assemblies and are provided such that they move the door assemblies between their respective open position, storage position and closed position. The double vertical pivot means are cranks pivoted at either end to permit pivoting of the door assemblies for storage within the rail car, when their panels are folded back upon one another. A lock for the doors includes a rigid projection extending from the edge of a first one of the panels behind and past an adjacent edge of the second of the two panels and in register with a cutout in the adjacent edge of the second panel. A locking bar is mounted on the second door for reciprocal movement in a vertical direction such that gravity can act to lock the door. A locking cam is pivotally mounted adjacent the bar for engagement with a stop projection on the bar to selectively permit the bar to be lifted.

摘要： A peripheral sealing gasket is disclosed for use in mounting a discharge gate to the adapter frame of a railroad hopper car. The gasket has a peripheral base formed of a relatively rigid sealing material, which base is formed and adapted to be positioned between and in substantial surface contact with a discharge gate mounting flange and the hopper car adapter frame. The base has at least one sealing element on each side thereof, which sealing elements extend outwardly beyond the base and are formed of a sealing material substantially less rigid than the base. There is a recess for each sealing element whereby each sealing element will distort into its recess during use so that the base is in substantial surface contact with the mounting flange and adapter frame throughout its peripheral extent.

摘要： A sliding gate for closing the discharge opening of a hopper having inclined side walls is mounted on elongated low-friction bodies or assemblies secured between the underside of upturned inclined side margins of the gate and the top sides of inclined side walls of a discharge chute secured to the hopper and extending below the discharge opening. The elongated low-friction bodies or assemblies are mounted to create a labyrinth seal by methods which include the use of a plurality of integral stud portions extending through corresponding openings along the inclined side margins of the gate, adhesives, keyways, welding or combinations thereof. The elongated low-friction bodies or assemblies are of a polymeric material such as nylon, Teflon or a composite material like ultra-high molecular weight polyethylene impregnated with molybdenum disulfide. The polymeric low-friction material may be molded to a metal matrix which is mounted on the gate by means of welding. Tapered sealing flaps for engagement with the lower portions of the inclined side walls of the hopper may be included in the low-friction bodies or assemblies.

摘要： A rail car having an interior cavity and an end opening for loading and unloading lading. A pair of door assemblies, each of which includes a plurality of panels, each pivotally movable with respect to the other for closing at least a portion of the end opening. Pivot means for mounting each of the door assemblies are provided to move the door assemblies between their respective open position and closed position. The pivot means are mounted for movement toward and away from the interior of the rail car to permit storage of the door assemblies within the rail car when their panels are folded back upon one another. The means for moving the pivot means include a guide means in the form of a pair of parallel racks and co-operating pinions drivingly mounted on a common manually driven shaft, one rack and co-operating pinion each at the top portion and the bottom portion of the door assembly. The rack and pinions function to keep the top and bottom portions in register as the folded door assemblies move along tracks extending normal the opening into the interior of the car for storage. The pinion driving shafts are manually driven and include pawl means which hold the doors in storage until the pawl is automatically removed from the teeth of its associated pinion upon manual pulling out of the door assembly. Intermediate locking means on the edges of horizontally disposed lading deck members adjacent the opening are provided, as well as a final locking means which includes a plurality of cams pivoted for movement in unison on a common locking shaft. The shaft includes a locking flange by which vertically movable interference means can selectively restrain the locking flange to prevent rotational movement of the locking shaft for unlocking of the doors. A pivoted sealing lug and appropriately positioned adjacent apertures on the lug and member prevent movement of the interference member during transit of the car.

摘要： An end tube assembly for the outlet gate of a railroad hopper car includes an end tube and an end tube cap for closing the end tube. The cap is pivotally connected to the end tube and there is a diametrically opposed latch between the cap and end tube. The cap has a guide which extends toward and over the end tube and there is a ramp on the end tube in alignment with the guide to coaxially direct the guide and cap on the end tube during closure. There is a lock on the end tube adjacent the ramp to prevent relative circumferential movement between the cap and end tube. The end tube mounts a gasket which faces the end tube cap. The cap has a rim extending outwardly therefrom for contact with the gasket. The extension of the rim gradually varies from at least one area of greatest extent to at least one area of lesser extent to compensate for distortion of the cap when it is latched onto the end tube.

摘要： This invention relates to a discharge trough for use in combination with a discharge gate of a railroad hopper car. The discharge gate has slanted side walls terminating in spaced, longitudinally extending lips which define a longitudinal discharge opening. The longitudinal trough has a somewhat rounded or circular cross section and merges with the lips of the slanted side walls to define the discharge opening. The slanted side walls are generally flat in the area adjacent the lips, with the lips having a rounded contour merging into the somewhat rounded inner wall of the trough. There is a rod-like discharge valve positioned within the trough adjacent and slightly below the lips to control the flow of material through the discharge opening.
