Abstract
Abstract A dumping vehicle comprising a dump body pivotally mounted on the vehicle chassis frame for movement between a horizontal normal position and an inclined dumping position using an air bag or air bellows as a means of power to raise and lower the dump body. The dump body is so pivoted and the air bellows is so disposed between the body and the chassis frame that maximum lift is obtained with a minimum stroke of the air bellows.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
185 words
A dump vehicle comprising a chassis having a frame, a dump body pivoted to said frame at a pivot axis for movement from a normal substantially horizontal position to an elevated inclined dumping position, and means for moving said body between said positions, said means comprising an air bellows connected between the frame and said dump body at a location spaced from said pivot axis, and means for controlling flow of air to and from said bellows; said body having a dump end, said pivot axis being spaced inwardly of the dump end, said air bellows being located inwardly of but closely adjacent said pivot axis; said air bellows being supported on the frame in normally upright position with its lower end connected to the frame, said dump body having a bottom, said bellows having its upper end connected to the bottom by a slidable pivot connection between the upper end of the bellows and the bottom, said connection permitting movement of the pivot thereof in a vertical direction only as the dump body is raised and lowered so as to maintain the bellows upright.
Claim 2
Dependent Claim
185 words
A dump vehicle comprising a chassis having a frame, a dump body pivoted to said frame at a pivot axis for movement from a normal substantially horizontal position to an elevated inclined dumping position, and means for moving said body between said positions, said means comprising an air bellows connected between the frame and said dump body at a location spaced from said pivot axis, and means for controlling flow of air to and from said bellows; said body having a dump end, said pivot axis being spaced inwardly of the dump end, said air bellows being located inwardly of but closely adjacent said pivot axis; said air bellows being supported on the frame in normally upright position with its lower end connected to the frame, said dump body having a bottom, said bellows having its upper end connected to the bottom by a slidable pivot connection between the upper end of the bellows and the bottom, said connection permitting movement of the pivot thereof in a vertical direction only as the dump body is raised and lowered so as to maintain the bellows upright.
Claim 3
Dependent Claim
97 words
A vehicle according to claim 1 in which the chassis frame includes a pair of longitudinally extending parallel support beams, said dump body being disposed transversely of said beams, said pivot axis being provided by a hinge structure connected to the bottom of the dump body adjacent a tailgate discharge end, said hinge structure being supported by a bracket structure extending outwardly from one of the beams, said air bellows being supported in the space between the beams and being anchored therein, the upper end of the bellows being connected to the bottom of said dump body.
Claim 4
Dependent Claim
32 words
A vehicle according to claim 2 in which the hinge is connected to the dump body at a point spaced inwardly of its discharge end adjacent the outer extremity of said bracket.
Claim 5
Dependent Claim
24 words
A vehicle according to claim 3 in which the upper end of the aiR bellows is fixed to the bottom of the dump body.
Claim 6
Dependent Claim
60 words
A vehicle according to claim 4 in which the upper end of the bellows is connected to the bottom of the dump body by a pivot which slides relative to the bottom of the body in a direction at right angles to the pivot axis during raising and lowering of the dump body to permit the bellows to remain upright.
Claim 7
Dependent Claim
21 words
A vehicle according to claim 3 in which the dump body is provided with a tailgate having an auxiliary gate thereon.
Claim 8
Dependent Claim
