Abstract
Abstract A farm utility wagon for carrying round or cylindrical bales with a center superstructure running from the front to the rear of the wagon. The superstructure can be raised or lowered by hydraulic cylinders. When the superstructure is in a lowered position it forms with the wagon base two parallel channels on to which two parallel rows of round or cylindrical bales can be set and moved. When the superstructure is raised, the bales are forced off to the side.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
187 words
A round bale hauler and unloader comprising; a wagon frame having a central longitudinal axis; one or more axles secured to the frame; wheels rotatably attached to said one or more axles for support and movement; an elevatable superstructure located along and parallel to the central longitudinal axis of the wagon frame and extending from the front to the rear of the wagon; and, means for raising the superstructure above the wagon frame and for lowering the superstructure onto a portion of the wagon frame, said portion of the wagon frame comprising wedge shaped structures fixedly attached along both top side edges of the wagon frame sloping inward toward the center of the wagon which form, with the superstructure when it is lowered onto the wedge shaped structures, two parallel side by side channels, wherein the bales can be loaded into each of the two parallel channels with the bale axis parallel to the longitudinal axis of the wagon, and unloaded by raising the superstructure above the wagon frame, thereby causing the bales to roll over the wedge shaped structures and off the sides of the wagon.
Claim 2
Dependent Claim
187 words
A round bale hauler and unloader comprising; a wagon frame having a central longitudinal axis; one or more axles secured to the frame; wheels rotatably attached to said one or more axles for support and movement; an elevatable superstructure located along and parallel to the central longitudinal axis of the wagon frame and extending from the front to the rear of the wagon; and, means for raising the superstructure above the wagon frame and for lowering the superstructure onto a portion of the wagon frame, said portion of the wagon frame comprising wedge shaped structures fixedly attached along both top side edges of the wagon frame sloping inward toward the center of the wagon which form, with the superstructure when it is lowered onto the wedge shaped structures, two parallel side by side channels, wherein the bales can be loaded into each of the two parallel channels with the bale axis parallel to the longitudinal axis of the wagon, and unloaded by raising the superstructure above the wagon frame, thereby causing the bales to roll over the wedge shaped structures and off the sides of the wagon.
Claim 3
Dependent Claim
33 words
A round bale unloader and hauler as claimed in claim 1 wherein the means to raise the superstructure is by a hydraulic cylinder which is powered by hydraulic lines connected to a tractor.
Claim 4
Dependent Claim
69 words
A round bale hauler and unloader as described in claim 2 wherein the hydraulic cylinder has an adjacent cylindrical reciprocating structure comprising two cylinders of different diameters, the larger of which is hollow so that the smaller can fit inside the larger with the one part of the cylindrical reciprocating structure attached to the superstructure and the other part of the cylindrical reciprocating structure attached to the wagon frame.
Claim 5
Dependent Claim
166 words
A round bale hauler and unloader comprising: a wagon frame having a central longitudinal axis with at least one axle with wheels attached thereto for support and movement; an elevatable superstructure located along and parallel to the central longitudinal axis of the wagon frame and extending from the front to the rear of the wagon; means for raising the superstructure above the wagon frame and for lowering the superstructure onto the wagon frame; wedge shaped structures fixedly attached to the top outside portion of the wagon frame sloping inward toward the center of the wagon frame and forming, with the superstructure when it is lowered onto the wedge shaped structures, two parallel channels wherein the bales can be loaded into each of the two parallel channels with the bale axis parallel to the longitudinal axis of the wagon, and unloaded by raising the superstructure above the wagon frame, thereby causing the bales to roll over the wedge shaped structures and off the sides of the wagon.
Claim 6
Dependent Claim
166 words
A round bale hauler and unloader comprising: a wagon frame having a central longitudinal axis with at least one axle with wheels attached thereto for support and movement; an elevatable superstructure located along and parallel to the central longitudinal axis of the wagon frame and extending from the front to the rear of the wagon; means for raising the superstructure above the wagon frame and for lowering the superstructure onto the wagon frame; wedge shaped structures fixedly attached to the top outside portion of the wagon frame sloping inward toward the center of the wagon frame and forming, with the superstructure when it is lowered onto the wedge shaped structures, two parallel channels wherein the bales can be loaded into each of the two parallel channels with the bale axis parallel to the longitudinal axis of the wagon, and unloaded by raising the superstructure above the wagon frame, thereby causing the bales to roll over the wedge shaped structures and off the sides of the wagon.
Claim 7
Dependent Claim
22 words
The round bale hauler as described in claim 4 further comprising reciprocating cylinders adjacent the means for raising and lowering the superstructure.
