20160023669 | Protective Structure for Tank Top Fittings - A railway tank car including a protective structure for the top of its cargo tank and surrounding both a valve group mounting nozzle and a pressure-relief safety valve nozzle, to protect the associated valves against damage resulting from the car being overturned, particularly while the railcar is moving along a railway. The protective structure includes protective housings including upstanding walls of metal plate construction surrounding the nozzles yet not attached directly to the nozzles, so that the protective housings afford convenient access to the valves associated with the nozzles. | 01-28-2016 |
20150336590 | OPERATING MECHANISM FOR TANK CAR BOTTOM VALVE - An operating mechanism for a bottom valve for a cargo tank of a railroad tank car, in which a valve operating lever is normally disconnected from a valve operating shaft and a valve operating shaft assembly includes a weak-link connector to prevent inadvertent opening of the bottom valve in case of derailment of the tank car. | 11-26-2015 |
20150291184 | Protective Structure for Tank Top Fittings - A railway tank car including a protective structure for the top of its cargo tank and surrounding a valve group mounting nozzle and a pressure relief safety valve nozzle, to protect the associated valves against damage resulting from the car being overturned, particularly while the railcar is moving along a railway. The protective structure includes an upstanding wall of metal plate that surrounds and is located at a radial distance outwardly apart from the tank top valve group mounting nozzle. A reinforcing band is attached to an upper portion of the upstanding wall to enhance its strength. Also disclosed is a method of protecting fittings mounted on a nozzle on the tank top of a railway tank car by providing and mounting such a protective structure to surround the tank top nozzle and associated fittings. | 10-15-2015 |
20150291183 | Protective Structure for Tank Top Fittings - A railway tank car including a protective structure for the top of its cargo tank and surrounding both a valve group mounting nozzle and a pressure relief safety valve nozzle, to protect the associated valves against damage resulting from the car being overturned, particularly while the railcar is moving along a railway. The protective structure includes protective housings including upstanding walls of metal plate construction surrounding the nozzles yet not attached directly to the nozzles, so that the protective housings afford convenient access to the valves associated with the nozzles. | 10-15-2015 |
20150284012 | Railroad Car for Carrying Motor Vehicles - A fully protective railroad freight car for carrying motor vehicles in a selected one of a bi-level or a tri-level configuration, with the lowest level including a depressed longitudinally central portion between body bolsters of the underbody, which may be a low-level flat car. A pair of vehicle-carrying decks are adjustable in height to provide for either one or two vehicle-carrying levels above the lowest level, while also providing at least a prescribed amount of vertical clearance above each vehicle-carrying deck. Ramps may be provided on the lowest level at an end of the car to provide a wheel-supporting surface having a prescribed minimum height. A roof structure is light in weight, and the car has an overall height not exceeding a prescribed limit for operation on most rail lines. The ends of the car are equipped with three-panel folding doors. | 10-08-2015 |
20150135986 | Protective Structure for Top of Tank Car - A railway tank car including a protective structure for the top of the tank and surrounding a manway or valve mounting nozzle to protect it against damage resulting from the car being overturned even while moving longitudinally. The protective structure may include longitudinally extending generally parallel side plates and a skid structure including longitudinally extending sloping, end portions and providing access to a manway or valve mounting assembly on the top of a nozzle. Openings may be provided in a side wall of the protective structure to give access to valve operating mechanisms extending laterally from valves. A lid for an access opening to a set of valves may include an extension that prevents a valve handle from being moved to open the valve while the lid is closed. | 05-21-2015 |
20140261071 | Railroad Car with Reinforced End Doors - A railroad freight car adapted for carrying automobiles and having a pair of doors enclosing and end of the car body. The pair of doors is hinged to the sides of the car body and meets each other at a central vertical plane, with each door including latches at top and bottom that engage an end sill and a roof the car body. The doors include panels of composite construction and have stiffening structures along vertically extending closure mating sides of the doors, whose margins confront each other. Door engagement members on each door extend toward and are engaged with the stiffening structures on the margin of the opposite one of the pair of doors. | 09-18-2014 |
20140123872 | RAILROAD CAR FOR CARRYING MOTOR VEHICLES - A fully protective railroad freight car for carrying motor vehicles in a selected one of a bi-level or a tri-level configuration, with the lowest level including a depressed longitudinally central portion between body bolsters of the underbody, which may be a low-level flat car. A pair of vehicle-carrying decks are adjustable in height to provide for either one or two vehicle-carrying levels above the lowest level, while also providing at least a prescribed amount of vertical clearance above each vehicle-carrying deck. Ramps may be provided on the lowest level at an end of the car to provide a wheel-supporting surface having a prescribed minimum height. A roof structure is light in weight, and the car has an overall height not exceeding a prescribed limit for operation on most rail lines. The ends of the car are equipped with three-panel folding doors. | 05-08-2014 |
20120043432 | Pipe anchor for railroad car - An assembly such as a pipe anchor to be mounted on a structural support member to hold a pipe or other elongate article in a desired location. A base portion includes a cradle having slide channels on a pair of opposite side walls. A clamping body includes flanges that fit in the slide channels. Locking tabs that may be extensions of the flanges may be bent to engage retention faces of retainer legs on the base portion to keep the clamping body in place, yet permit it to be removed by straightening the locking tabs. | 02-23-2012 |
