发明名称 Hopper car gate with opposed double doors
摘要 A hopper car gate with opposed double doors for discharging cargo from a hopper car. The gate has joined side walls and end walls which present top and bottom openings. A flange joined to the walls adjacent the top opening is adapted to be joined to the hopper car. A rail extends between opposite walls adjacent the bottom opening. First and second doors are supported on the rail. The doors are moveable in opposite directions between a closed position which blocks the bottom opening and an open position which allows the cargo to exit through the opening.
