    Abstract: A hopper car discharge outflow is controlled by closure members, at least one of which is movable. The doors are hingeless, being mounted on four bar linkages, such that the distal edge of the doors sweeps predominantly horizontally while the proximal edge of the door moves predominantly upwardly. The doors move through noncircular arcs, such that the size of the vertically projected door opening is abnormally large compared to the clearance heights of the door. The doors are driven by a longitudinal shaft that is mounted within the center sill. It drives a set of single input, double output bell cranks that drive adjacent pairs of doors, and that employs an over-center toggle to hold the doors in the closed position when the car is laded. The actuators may be mounted in shelters midway along the car, and may be offset from the centersill. The actuators may be mounted predominantly vertically such that gravity may obviate the need for a secondary lock.

  • Patent number: 7823514
    Abstract: A hopper car has arcuate side sheets that are bent over the forming members of the structure to give a generally outwardly bulging shape. The upper margin of the side sheet is kinked inwardly of the radius of curvature of the larger portion of the side sheet more generally, such as may tend to impose a bending moment on the large, relatively thin side sheet panels. This may in turn tend to urge or bias those panels to a bulging position or shape, rather than a sagging, deflected, or inwardly dented position.

  • Patent number: 7814842
    Abstract: A hopper car gate for discharging cargo from a hopper car having a length greater than its width. The gate has opposed generally upright side walls and opposed generally upright end walls coupled with the side walls. The coupled walls present a top opening and a bottom opening. A first rail extends between and is coupled with the side walls adjacent the bottom opening. A first door is supported on the first rail and is moveable in a direction that is perpendicular to the length of the hopper car that the gate is joined with between a closed position which blocks the bottom opening and an open position which allows cargo to exit through the bottom opening.

  • Publication number: 20100251922
    Abstract: A railroad gondola car has a hopper carried between two trucks. The hopper has convergent end and side slope sheets that feed a bottom discharge. The bottom discharge has a pair of longitudinal doors. The door closing mechanism is a mechanical transmission that includes a set of linkages running from the door to a reciprocating pneumatic cylinder. The linkages run generally parallel to the slope sheet. The car has a very short draft installation that includes a removable coupler carrier bar, and the main shear plate has a removable draft gear installation panel. There is a machinery space above the end section shear plate. It is overhung by the slope sheet that is substantially unobstructed by any other primary structure. The pneumatic cylinder is mounted on an angle in this unobstructed machinery space, oriented longitudinally over the draft sill beneath the main drag link of the mechanical transmission, and above the main pivot of the driving input lever of the transmission.

  • Publication number: 20100251923
    Abstract: A hopper car discharge outflow is controlled by closure members, at least one of which is movable. The doors are hingeless, being mounted on four bar linkages, such that the distal edge of the doors sweeps predominantly horizontally while the proximal edge of the door moves predominantly upwardly. The doors move through noncircular arcs, such that the size of the vertically projected door opening is abnormally large compared to the clearance heights of the door. The doors are driven by a longitudinal shaft that is mounted within the center sill. It drives a set of single input, double output bell cranks that drive adjacent pairs of doors, and that employs an over-center toggle to hold the doors in the closed position when the car is laded. The actuators may be mounted in shelters midway along the car, and may be offset from the centersill. The actuators may be mounted predominantly vertically such that gravity may obviate the need for a secondary lock.

  • Patent number: 7536957
    Abstract: A flow through railroad freight car may include a body having a containment structure. The body may be mounted upon railcar trucks for rolling motion along railroad car tracks. The containment structure may include one or more hoppers, each of which may have inflow and outflow ports, by which means lading may be introduced into the car, or discharged from it. The inflows may include an upper intake, which may be a series of hatches and hatch coamings. The hatch coamings may stand outwardly from the containment structure, and may also having internally extending skirts. In one instance, the skirts may be of a first length corresponding to a first fill level, or volume, for use with lading of a first density. The length of the skirt may be adjusted at a later time to correspond to a second fill level, or volume, for use with lading of a second density.

  • Publication number: 20080066642
    Abstract: A hopper car discharge section may be wide at the top and narrow at the bottom. Outflow is controlled by closure members, at least one of which is movable. The closure members come together to a closed condition or position for retaining lading. When apart, in an open position or condition, lading may be discharged. A seal member or seal member assembly is mounted to one or both of the closure members. When open, the seal member or seal member assembly lies substantially flush with, or shy of, the slope of the surface of the closure member. When closed, the seal member may be self-energizing, in the sense that as lading is added the seal may tend to seal more tightly. The seal assembly may include a cantilevered spring that presents a land to the opposed closure member, and a fulcrum, over, or across, which the spring is cantilevered, such that pushing down on one end of the spring may tend to cause the other end to flex upward.

    Abstract: In a method of loading several like coupled storage cars with bulk material, a first storage car is first filled with the bulk material by reducing the conveying speed mode of a bottom conveyor band in the first storage car to a bulk material storing speed mode while a transfer conveyor band of the adjacent storage car fills the first storage car, the storing speed mode of the bottom conveyor band in the first storage car is automatically adjusted in response to a measured amount of the bulk material accumulating in a pile so that the first storage car is filled to a maximal height, and after the accumulated pile has reached a forward end position, the conveying speed mode of the bottom conveyor band in the storage car adjacent to, and rearwardly of, the first storage car in the conveying direction is automatically reduced to the storing speed mode.

  • Patent number: 7171907
    Abstract: A drive system for a railway hopper car discharge gate includes a door panel operated by a rack and pinion drive. The pinion teeth present a substantially cylindrical profile in a plane orthogonal to the axis of pinion rotation. The cylindrical tooth profile substantially prevents the pinion teeth from skipping or walking against the rack teeth when the spacing between the pinion and the door panel and associated rack fluctuates during operation of the discharge gate. Pinion torque is converted into a vertical force at the ends of travel of the door panel to prevent damage to the drive components. A bearing arrangement supports a drive shaft that is operated to rotate the pinions, and minimizes deflection of the shaft when under rotational load. An inertia brake is provided to engage the door panel and prevent it from opening upon a rapid stop of the hopper car as may occur upon impact with an adjacent railway car.

The hopper closure assembly may have a raising structure which lifts the gate relative to the gate frame to create potential energy to assist in movement of the gate down the raising structure and in opening the discharge opening of the hopper. A method of using a hopper closure assembly which involves the steps opening the discharge opening by moving the gate longitudinally, also including the steps permitting the granular material to assist in opening the gate by striking the angled member, and additionally permitting the leading edge to move from the receiving member of the gate frame by descent from the raising structure.
