Abstract
Abstract A chassis supports a main frame with one open side, and a dump box with an open upper side is situated within the main frame and pivoted to the other side of the main frame. An hydraulic piston and cylinder assembly can move the box from the vertical or normal position to a tilted or unloading position. The dump box is pivoted to the upper side of the main frame at a line spaced from the top side edge of the dump box so that the top side edge extends beyond the side of the wagon when tipped or tilted. A conveyor is situated on the side of the dump box which is pivoted to the main frame and driven by an hydraulic motor. Material is loaded in the open upper side of the dump box and when it is to be unloaded, the dump box is tilted whereupon the conveyor unloads the material from the open upper side of the dump box. This construction overcomes disadvantages of conventional dump boxes in which the center of gravity is shifted considerably when dumping by gravity, particularly when the load is such that it resists sliding movement during dumping. Furthermore, conventional dump boxes are usually pivoted adjacent the top edge thereof which dumps the load close to the side of the receptacle into which it is being dumped rather than towards the center as with the present device due to the fact that the upper edge of the box is spaced away from the chassis.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
153 words
A power dump wagon comprising in combination a supporting main frame, a dump wagon box mounted within said main frame, means for mounting said box by one side thereof within said main frame for tilting movement relative thereto, from a substantially vertical, normal position to an inclined uploading position and vice versa, an endless unloading conveyor operatively mounted upon said one side of said box and extending substantially the full length and breadth thereof, said unloading conveyor being substantially vertical when said box is in the said normal position, and including an outer run and an inner run spaced and parallel with said outer run and situated between said outer run and said one side, means to move said box from one position to the other and further means to operate said conveyor wherein said outer run moves upwardly from adjacent the lower end of said one side towards the upper end thereof.
Claim 2
Dependent Claim
153 words
A power dump wagon comprising in combination a supporting main frame, a dump wagon box mounted within said main frame, means for mounting said box by one side thereof within said main frame for tilting movement relative thereto, from a substantially vertical, normal position to an inclined uploading position and vice versa, an endless unloading conveyor operatively mounted upon said one side of said box and extending substantially the full length and breadth thereof, said unloading conveyor being substantially vertical when said box is in the said normal position, and including an outer run and an inner run spaced and parallel with said outer run and situated between said outer run and said one side, means to move said box from one position to the other and further means to operate said conveyor wherein said outer run moves upwardly from adjacent the lower end of said one side towards the upper end thereof.
Claim 3
Dependent Claim
46 words
The dump wagon according to claim 1 in which said box is mounted by said one side thereof for tilting movement about a line spaced downwardly from the top of said box whereby said top is spaced from said main frame when in the unloading position.
Claim 4
Dependent Claim
22 words
The dump wagon according to claim 1 in which said box includes an open top and detachable cover means for said top.
Claim 5
Dependent Claim
22 words
The dump wagon according to claim 2 in which said box includes an open top and detachable cover means for said top.
Claim 6
Dependent Claim
34 words
A power dump wagon according to claim 1 in which said main frame includes an open side opposite to the side of said main frame within which said box is mounted for tilting movement.
Claim 7
Dependent Claim
34 words
A power dump wagon according to claim 2 in which said main frame includes an open side opposite to the side of said main frame within which said box is mounted for tilting movement.
Claim 8
Dependent Claim
34 words
A power dump wagon according to claim 3 in which said main frame includes an open side opposite to the side of said main frame within which said box is mounted for tilting movement.
Claim 9
Dependent Claim
34 words
A power dump wagon according to claim 4 in which said main frame includes an open side opposite to the side of said main frame within which said box is mounted for tilting movement.
Claim 10
Dependent Claim
55 words
The dump wagon according to claims 1, 2 or 3 in which said means to move said box from one position to the other comprises at least one fluid operator operatively extending between said box and said main frame, and said means to operate said conveyor comprises an hydraulic motor operatively connected to said conveyor.
Claim 11
Dependent Claim
55 words
The dump wagon according to claims 3, 4 or 5 in which said means to move said box from one position to the other comprises at least one fluid operator operatively extending between said box and said main frame, and said means to operate said conveyor comprises an hydraulic motor operatively connected to said conveyor.
Claim 12
Dependent Claim
55 words
The dump wagon according to claims 6, 7 or 8 in which said means to move said box from one position to the other comprises at least one fluid operator operatively extending between said box and said main frame, and said means to operate said conveyor comprises an hydraulic motor operatively connected to said conveyor.
Claim 15
Dependent Claim
93 words
The dump wagon according to claims 3, 4 or 7 in which said means to move said box from one position to the other comprises at least one fluid operator operatively extending between said box and said main frame, and said means to operate said conveyor, comprises an hydraulic motor operatively connected to said conveyor, and linkage means operatively extending between said main frame, said box and said cover means whereby said cover means opens when said box is moved from the vertical normal position to the inclined unloading position and vice versa.
Claim 16
Dependent Claim
90 words
The dump wagon according to claim 8 in which said means to move said box from one position to the other comprises at least one fluid operator operatively extending between said box and said main frame, and said means to operate said conveyor, comprises an hydraulic motor operatively connected to said conveyor, and linkage means operatively extending between said main frame, said box and said cover means whereby said cover means opens when said box is moved from the vertical normal position to the inclined unloading position and vice versa.
