Abstract
Abstract The present invention provides an apparatus for cutting the long stalks making up a hay stack into short sections more suitable for cattle feed. The arrangement includes a vertical array of disintegrating rolls for breaking up the hay stack and delivering the stems to a plurality of material distributing devices which distribute and feed the stems in a uniform fashion to a cutter roll which chops the stems into short lengths. In the operation of the apparatus, the stems making up the hay may be delivered repeatedly to the cutter roll to assure cutting to the proper length.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
144 words
Apparatus for reducing a hay stack to a short length cattle feed comprising an elongated bed, a vertical array of disintegrating rolls rotatably mounted at one end of the bed, a conveyor for moving a hay stack on the bed into said disintegrating rolls, a first material distributing means extending across the bed below the disintegrating rolls and adapted to move material disintegrated by the rolls in one direction across the bed, a second material distributing means beneath the first material distributing means and adapted to move material received from said first material distributing means across the bed in the opposite direction, a rotatably mounted cutter roll positioned to receive material from said material distributing means, means for moving material transversely across the face of the cutter roll toward one end thereof, and a material discharge means at said end of the cutter roll.
Claim 2
Dependent Claim
144 words
Apparatus for reducing a hay stack to a short length cattle feed comprising an elongated bed, a vertical array of disintegrating rolls rotatably mounted at one end of the bed, a conveyor for moving a hay stack on the bed into said disintegrating rolls, a first material distributing means extending across the bed below the disintegrating rolls and adapted to move material disintegrated by the rolls in one direction across the bed, a second material distributing means beneath the first material distributing means and adapted to move material received from said first material distributing means across the bed in the opposite direction, a rotatably mounted cutter roll positioned to receive material from said material distributing means, means for moving material transversely across the face of the cutter roll toward one end thereof, and a material discharge means at said end of the cutter roll.
Claim 3
Dependent Claim
135 words
Apparatus for reducing a hay stack to a short length cattle feed comprising an elongated bed, a vertical array of disintegrating rolls rotatably mounted at one end of the bed, a conveyor for moving a hay stack on the bed into said disintegrating rolls, a first auger extending across the bed below the disintegrating rolls and arranged to move material disintegrated by the rolls in one direction across the bed, a second auger beneath the first auger and arranged to move material received from the first auger across the bed in the opposite direction, a rotatably mounted toothed cutter roll positioned to receive material from said augers, means for moving material transversely across the face of the cutter roll toward one end thereof, and a material discharge means at said end of the cutter roll.
Claim 4
Dependent Claim
135 words
Apparatus for reducing a hay stack to a short length cattle feed comprising an elongated bed, a vertical array of disintegrating rolls rotatably mounted at one end of the bed, a conveyor for moving a hay stack on the bed into said disintegrating rolls, a first auger extending across the bed below the disintegrating rolls and arranged to move material disintegrated by the rolls in one direction across the bed, a second auger beneath the first auger and arranged to move material received from the first auger across the bed in the opposite direction, a rotatably mounted toothed cutter roll positioned to receive material from said augers, means for moving material transversely across the face of the cutter roll toward one end thereof, and a material discharge means at said end of the cutter roll.
Claim 5
Dependent Claim
156 words
Apparatus for reducing a hay stack to a short length cattle feed comprising an elongated bed, a vertical array of disintegrating rolls rotatably mounted at one end of the bed, a conveyor for moving a hay stack on the bed into said disintegrating rolls, a first auger extending across the bed below the disintegrating rolls and arranged to move material disintegrated by the rolls in one direction across the bed, a second auger beneath the first auger and arranged to move material received from the first auger across the bed in the opposite direction, a rotatably mounted toothed cutter roll positioned to receive material from said augers, a third auger positioned parallel to but above the cutter roll to receive material from the cutter roll and reintroduce it thereinto, said third auger serving to move material transversely of the cutter roll toward one end thereof, and material discharge means at said end of the cutter roll.
