Dump body with self-cleaning, fold down side doors

A dump body, which comprises:

• a generally rectangular bottom wall having front and rear ends;
• means including interconnected longitudinal and transverse from members secured beneath said bottom wall;
• pairs of spaced-apart upright front and rear posts secured to the front and rear ends, respectively, of said bottom wall;
• a front wall secured between said front posts and the front end of said bottom wall;
• said doors positioned between associated front and rear posts, each side door including top and bottom ends;
• means for pivotally securing the bottom end of each side door to said bottom wall for movement over an obtuse angle between raised and lowered positions;
• the bottom ends of said side doors and adjacent portions of said bottom wall both being angled downwardly and outwardly at complementary angles in order to shed material therefrom when said side door is in the lowered position without tilting the dump body;
• a pair of pins mounted at opposite sides of each side door for movement between extended positions in registry with holes in the adjacent front and rear posts, and retracted positions;
• means for normally biasing said pins toward the extended positions to secure each side door in the raised position;
• a lever pivoted to each side door between said pins;
• means for connecting said lever to said pins for selective manual actuation thereof toward the retracted position in order to release said side door for movement toward the lowered position;
• a hinged rear door secured between said rear posts for movement between open and closed positions;
• and
• means for releasably securing said rear door in the closed position.

A dump body, which comprises:

• a generally rectangular bottom wall having front and rear ends;
• means including interconnected longitudinal and transverse frame members secured beneath said bottom wall;
• pairs of spaced-apart upright front and rear posts secured to the front and rear ends, respectively, of said bottom wall;
• a front wall secured between said front posts and the front end of said bottom wall;
• side doors positioned between associated front and rear posts, each side door including top and bottom ends;
• means for pivotally securing the bottom end of each side door to said bottom wall for movement over about 180 degrees between raised and lowered positions;
• the bottom ends of said side doors and adjacent portions of said bottom wall both being angled downwardly and outwardly at complementary angles in order to shed material therefrom when said door is in the lowered position without tilting the dump body;
• means for releasably securing each side door in the raised position;
• a rear door positioned between said rear posts, said rear door having top and bottom ends;
• means for releasably securing the top end of said rear door to said rear posts for pivotal movement about an upper transverse axis between opened and closed positions;
• and
• means for releasably securing the bottom end of said rear door to said rear posts for pivotal movement about a lower axis between raised and lowered positions, the upper and lower axes being longitudinally offset so that said rear door is normally biased by gravity about said upper axis toward the closed position.
