Rail car door opener

A servo that is attachabley secured to the rail car frame at each door lock that is connected to the latch via a draw bar with sufficient modulus to withstand the repeated force required to move the latch thus opening the door. The servo provides a pulling action with the motive force being pneumatic pressure but not limited to pneumatic whereas hydraulic or electric energy can be supplied to the servo providing the motive force to pull the draw bar attached to the latch, that when said servo provides a pulling force sufficient to over come the friction ot the latch to the striker plate the latch moves in a upward direction thus releasing the door to open. A second element of the servo is to provide a pushing action via the draw bar to the door latch to drive it all the way into the closed position.

Rail road hopper car fittings and method of operation

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. The fulcrum may also be cantilevered outward from the slope sheet of the closure member to which the seal assembly is attached. The discharge section may be robustly reinforced to discourage deformation.

Railroad car and door mechanism therefor

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 transverse drive linkage that is driven by a transversely mounted actuator. The actuator is mounted in an accommodation in the lee of slope sheets between adjacent hoppers in a mid-span portion of the car. Drive from the actuator is carried to a pair of symmetrically mounted doors through drive train linkages. The drive train includes longitudinally extending torque tubes that transmit drive to both fore and aft ends of the door assemblies. The car also has a lost motion secondary lock system, an alternate manual drive door opening and closing drive train, and abnormally high side sills and a center sill that passes clear through the discharge sections at a height clearly lower than the upper margin of the discharge sections.
