Abstract: A convertible railway hopper car has parallel longitudinal beams defining the sides of a hatchway for filling the car with granular material from a spout, and hinged on the upper margins of the car sidewalls are cargo cover members which may occupy elevated positions in which they form a roof covering the entire car body except the hatchway, or idle positions hanging inside the car body. Hinged hatch elements are mounted on the cargo cover members at one side of the hatchway and are movable between extended positions closing the hatchway and secured to the cargo cover members at the other side of the hatchway, and open positions lying atop the cargo cover members upon which they are mounted. When the cargo cover members are in idle position the hatch elements hang below them.

Abstract: A dual discharge hopper device for the cargo body of a bulk cargo carrying wheeled vehicle has at least one transverse side wall which is pivoted and releasably latched for free discharge of material from the cargo body, and also has a bottom closure which provides for controlled discharge of material. A diverter panel is mounted on a shaft at the bottom of the device alongside the pivoted side wall, and is movable between a controlled discharge position in which it confronts the pivoted sidewall, and a free discharge position in which it lies diagonally across the device to block the controlled discharge closure. Two opposite sidewalls may be pivoted, in which case there are two diverter panels the upper ends of which effectively meet to block the controlled discharge closure.
