摘要: A discharge gate assembly for a railroad hopper car is disclosed. The gate assembly includes a frame defining a discharge opening and a gate or first element slidably carried on the frame for controlling the discharge of material from the hopper car through the discharge opening. The gate assembly further includes a second slidable element carried by the frame in vertically spaced relation relative to the first element and extending across the discharge opening. A first drive mechanism including a first operating shaft assembly is mounted on the gate frame for slidably moving the first element relative to the frame. A second drive mechanism including a second operating shaft assembly is also mounted on the gate frame for slidably moving the second element relative to the gate frame. The operating shaft assemblies are mounted for rotation about independent fixed axes and in horizontally adjacent relation relative to each other. A single lock assembly is also provided for releasably but separately holding the first and second element in a closed position. The second slidable element is preferably configured as an open top pan assembly having outlet tubes extending laterally therefrom. A closure assembly including an end cap or cover is provided in combination with a free end of each outlet tube allowing for one-handed operation of the closure assembly.

摘要: A gate assembly for a railroad hopper car is disclosed. The gate assembly includes a frame defining a discharge opening, a slidable door mounted on the frame for movement between a closed position, wherein the door closes the discharge opening, and an open position, wherein the door is positioned to allow commodity to pass through the discharge opening. Either of two modular components can be arranged in combination with the door on the gate assembly to allow the gate assembly to be conditioned for either pneumatic and/or gravitational discharge or gravitational discharge only of commodity from the gate assembly. A drive mechanism including an apparatus for selectively engaging either the door or either of the modular elements arranged in association with the door is mounted on the frame of the gate assembly, with the apparatus of the drive mechanism preferably being lost motion connected to the door. Seal structure is provided in combination with the frame, door and a modular element for inhibiting debris from contaminating the door and a discharge plenum defined by the frame of the gate assembly.
