Dual discharge hopper device for bulk cargo vehicles

A dual discharge hopper device for the cargo body of a bulk cargo carrying wheeled vehicle, said body having a bottom wall provided with a rectangular opening, said dual discharge hopper device comprising, in combination:

• a depending structure having two fixed sidewalls which bound first parallel sides of said rectangular opening, and two connecting walls which bound second parallel sides of said opening, one of said connecting walls being mounted on a pivot the axis of which extends between the fixed sidewalls immediately adjacent the bottom of the cargo body so that said one of said connecting walls may selectively abut the fixed sidewalls or swing clear of said sidewalls for uncontrolled discharge of material from the cargo body;
• controlled discharge closure means at the lower end of said depending structure;
• discharge control means for moving said controlled discharge closure means to any desired point between a closed position in which it completely blocks the lower end of the structure and a fully open position in which said lower end is effectively unobstructed;
• and a diverter panel mounted on a horizontal shaft that extends between the lower ends of the sidewalls immediately adjacent said one of said connecting walls, said diverter panel being movable between a generally upright controlled discharge position confronting said one of the connecting walls, and an uncontrolled discharge position inclined across the structure so the lower end of the structure is completely obstructed.
