Abstract
Abstract A wagon for transporting and dumping material having an improved dumping mechanism which provides a relatively low and stable transport position of the material container while providing a relatively high dumping position of the container, in which the pouring edge along the side of the container is significantly higher in the dumping position than in the transport position. A moveable guide member and a connecting link cooperate when actuated by a hydraulic ram to move the material container outward along a pivot arm, thereby providing the increase in dumping height as the hydraulic ram further rotates the pivot arm to dump the container.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
149 words
A dumping mechanism for a dump vehicle having a wheeled transport carriage and a material container moveable thereon from a transport position to a dumping position, comprising: a. a support frame attached to the wheeled transport carriage; b. a pivot arm pivotally connected to said support frame; c. means attached to said material container at an upper portion thereof for mounting said material container to said pivot arm with one side of said container adjacent the pivot point for relative movement of the container therealong between a transport position toward the pivot point and a dumping position away from the pivot point, said mounting means providing at least partial support for the material container; and d. actuation means operably connected for moving the material container along the pivot arm away from the pivot point to the dumping position and for rotating the pivot arm to dump the material container.
Claim 2
Dependent Claim
149 words
A dumping mechanism for a dump vehicle having a wheeled transport carriage and a material container moveable thereon from a transport position to a dumping position, comprising: a. a support frame attached to the wheeled transport carriage; b. a pivot arm pivotally connected to said support frame; c. means attached to said material container at an upper portion thereof for mounting said material container to said pivot arm with one side of said container adjacent the pivot point for relative movement of the container therealong between a transport position toward the pivot point and a dumping position away from the pivot point, said mounting means providing at least partial support for the material container; and d. actuation means operably connected for moving the material container along the pivot arm away from the pivot point to the dumping position and for rotating the pivot arm to dump the material container.
Claim 3
Dependent Claim
28 words
A dumping mechanism according to claim 1 wherein said mounting means includes a guide member attached to the container and moveably engaging said pivot arm for support thereby.
Claim 4
Dependent Claim
33 words
A dumping mechanism according to claim 2 wherein said pivot arm includes a stop member engageable by said guide member when the container has moved a predetermined distance away from the pivot point.
Claim 5
Dependent Claim
40 words
A dumping mechanism according to claim 2 wherein said guide member comprises a pair of brackets spaced on either side of said pivot arm, and a roller attached between said brackets for engaging the top surface of said pivot arm.
Claim 6
Dependent Claim
33 words
A dumping mechanism according to claim 4 further including a pair of stop blocks attached to said pivot arm for engagement by said brackets when the container is moved to its dumping position.
Claim 7
Dependent Claim
51 words
A dumping mechanism according to claim 1 wherein said actuation means includes a bell crank pivotally connected to the container and having one end pivotally connected To said pivot arm, and wherein said actuation means further includes means for applying an actuation force to the other end of the bell crank.
Claim 8
Dependent Claim
30 words
A dumping mechanism according to claim 6 wherein said force applying means comprises a hydraulic ram connected between said other end of the bell crank and the wheeled transport carriage.
Claim 9
Dependent Claim
134 words
A dump vehicle comprising: a. a wheeled transport carriage; b. a material container; c. a support frame attached to said wheeled transport carriage; d. a pivot arm; e. means for mounting said material container to said pivot arm for relative movement of the container therealong between a transport position toward the pivot point and a dumping position away from the pivot point, said mounting means providing at least partial support for the material container; f. a connecting link pivotally connected to said material container and to said pivot arm; and g. an extensible member connected to said wheeled transport carriage and to said connecting link for applying the actuating force to move the material container along the pivot arm to its dumping position, and to rotate the pivot arm to dump the material container.
Claim 10
Dependent Claim
134 words
A dump vehicle comprising: a. a wheeled transport carriage; b. a material container; c. a support frame attached to said wheeled transport carriage; d. a pivot arm; e. means for mounting said material container to said pivot arm for relative movement of the container therealong between a transport position toward the pivot point and a dumping position away from the pivot point, said mounting means providing at least partial support for the material container; f. a connecting link pivotally connected to said material container and to said pivot arm; and g. an extensible member connected to said wheeled transport carriage and to said connecting link for applying the actuating force to move the material container along the pivot arm to its dumping position, and to rotate the pivot arm to dump the material container.
Claim 11
Dependent Claim
28 words
A dump vehicle according to claim 8 wherein said mounting means includes a guide member attached to the container and moveably engaging said pivot arm for support thereby.
Claim 12
Dependent Claim
28 words
A dump vehicle according to claim 8 wherein said connecting link comprises a bell crank having ends pivotally connected to said pivot arm and to said extensible member.
Claim 13
Dependent Claim
25 words
A dump vehicle according to claim 10 wherein said extensible membr comprises a hydraulic ram connected between the wheeled transport carriage and the connecting link.
Claim 14
Dependent Claim
74 words
A dump vehicle according to claim 8 wherein said material container has a pouring edge formed on the top edge of one side of the container, and wherein said one side slopes downwardly from the pouring edge and inwardly toward the interior of said material container when the container is in its transport position, said sloping side thereby forming an inclined ramp to urge material downwardly when said container is in its dumping position.
Claim 15
Dependent Claim
56 words
A dump vehicle according to claim 12 wherein said support frame comprises at least one transverse support strut sloping upwardly from said wheeled transport carriage along a line parallel to said sloping side of the container in its transport position, said transverse support strut for abutment by and stabilization of said container in its transport position.
