Patent number: 9272717Abstract: A hopper car discharge section may be wide at the top and narrow at the bottom. Outflow is controlled by movable closure members. The hopper car has a plurality of hoppers of which two hoppers share a common ridge assembly. The ridge assembly forms a common mating and fit up location for the upper margins of the slope sheets of two lengthwise adjacent hoppers. The ridge assembly includes an horizontal center section and two end plates that angle upwardly outboard toward the top chords of the sidewalls. The ridge assembly stands proud of the upper margin of the respective adjacent slope sheets. A gusset is mounted between the adjacent slope sheets below the ridge plate such that the slope sheets and gusset form a reinforcement tube running across the car, the end plates forming the stems of a vertical T-section attached to the sidewall and overlapping the top chord.Type: GrantFiled: December 13, 2013Date of Patent: March 1, 2016Assignee: NATIONAL STEEL CAR LIMITEDInventors: James W. Forbes, Mohamed A. Khattab, Tomas Bis, William R. Davis

Patent number: 7703397Abstract: 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.Type: GrantFiled: September 8, 2006Date of Patent: April 27, 2010Assignee: National Steel Car LimitedInventors: James W.
