Claim 5

In a self-unloading wagon having a box including an end wall, a cross convEyor including a U-shaped trough disposed within the box along said end wall and an auger disposed in the trough for discharging material through an opening in the side of the box, wherein the improvement comprises: A a U-shaped frame member mounted on the side of the box in registration with an end of the cross conveyor trough; a U-shaped extension trough having an intake end mounted on said frame member in receiving relation with the cross conveyor and terminating in a discharge end; means mounting said extension trough for pivoting movement about a generally horizontal axis proximate to said intake end whereby said discharge end may be raised and lowered; an extension auger disposed in said extension trough for conveying material therealong; universal joints means drivingly connecting the cross conveyor auger with said extension auger thereby accommodating pivoting movement about said horizontal axis while maintaining the driving connection; and means mounting said frame member for selectively pivoting said extension trough about an axis transverse to said first mentioned axis to horizontally swing the same to a transport position out of receiving relation with the cross conveyor.

Claim 6

The subject matter of claim 3, wherein said universal joint means includes a pair of interfitting sections mounted on the cross conveyor auger and on the extension auger respectively, said sections being separable to permit swinging of said extension trough out of receiving relation with the cross conveyor.

Claim 7

In a self-unloading wagon having a box including an end wall, a cross conveyor including a U-shaped trough disposed within the box along said end wall and an auger disposed in the trough for discharging material through an opening in the side of the box, wherein the improvement comprises: a U-shaped frame member mounted on the side of the box in registration with an end of the cross conveyor trough; a U-shaped extension trough having an intake end mounted on said frame member in receiving relation with the cross conveyor and terminating in a discharge end; means mounting said extension trough for pivoting movement about a horizontal axis proximate to said intake end whereby said discharge end may be raised and lowered; an extension auger disposed in said extension trough for conveying material therealong; universal joint means drivingly connecting the cross conveyor auger with said extension auger thereby accommodating pivoting movement about said horizontal axis while maintaining the driving connection; and means mounting said frame member for pivoting movement relative to the side of the box and including hinge means mounted proximate to the juncture of the end wall and sidewall of the box, said hinge means defining a vertical pivot axis about which said frame member is swingable out of receiving relation with the cross conveyor to dispose the same into a transport position substantially parallel to and adjacent to the end wall.

Claim 8

In a self-unloading wagon having a box including an end wall, a cross conveyor including a U-shaped trough disposed within the box along said end wall and an auger disposed in the trough for discharging material through an opening in the side of the box, wherein the improvement comprises: a U-shaped frame member mounted on the side of the box in registration with an end of the cross conveyor trough; a U-shaped extension trough having an intake end mounted on said frame member in receiving relation with the cross conveyor and terminating in a discharge end; means mounting said extension trough for pivoting movement about a horizontal axis proximate to said intake end whereby said discharge end may be raised and lowered; an extension auger disposed in said extension trough for conveying material therealong; universal joint means drivingly connecting the cross conveyor auger with said extension auger thereby accommodating pivoting movement about said horizontal axis while maintaining the driving connection; and means mounting said frame member for pivoting movement relative to the side of the box and including hinge means mounted proximate to the juncture of the end wall and sidewall of the box, said hinge means defining a vertical pivot axis about which said frame member is swingable out of receiving relation with the cross conveyor to dispose the same into a transport position substantially parallel to and adjacent to the end wall.

Claim 9

In a self-unloading wagon having a box including an end wall, a cross conveyor including a U-shaped trough disposed within the box along said end wall and an auger disposed in the trough for discharging material through an opening in the side of the box, wherein the improvement comprises: a U-shaped frame member mounted on the side of the box in registration with an end of the cross conveyor trough; a U-shaped extension trough having an intake end mounted on said frame member in receiving relation with the cross conveyor and terminating in a discharge end; means mounting said extension trough for pivoting movement about a horizontal axis proximate to said intake end whereby said discharge end may be raised and lowered; an extension auger disposed in said extension trough for conveying material therealong; universal joint means comprising a pair of interfitting sections mounted on the cross conveyor auger and on the extension auger respectively, sAid sections being operative for drivingly connecting the cross conveyor auger with said extension auger thereby accommodating pivoting movement about said horizontal axis while maintaining the driving connection and separable to permit swinging of said extension trough into said transport position; and means mounting said frame member for pivoting movement relative to the side of the box and including hinge means mounted proximate to the juncture of the end wall and sidewall of the box, said hinge means defining a vertical pivot axis about which said frame member is swingable out of receiving relation with the cross conveyor to dispose the same into a transport position substantially parallel to and adjacent to the end wall.
