Abstract
Abstract The present invention provides an apparatus for disintegrating hay stacks which includes a bed upon which a hay stack is placed, a conveyor on the bed for moving the stack toward a plurality of vertically arranged rolls to disintegrate or pull apart the hay stack, dropping the hay into a well from which it is fed into a cutting roll which cuts the hay into small pieces suitable for immediate consumption by cattle.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
103 words
Apparatus of the character described comprising, a bed of a size sufficient to receive and support a hay stack; a conveyor on the bed; a vertical array of horizontally arranged toothed rolls rotatably mounted at one end of the bed, said array being of hay stack height and extending transversely substantially the width of the bed; a hay chopper at said end of the bed; means for rotating the rolls; means for operating the conveyor to feed a hay stack on the bed into the rolls to disintegrate the stack; and means for feeding hay disintegrated by the rolls into the hay chopper.
Claim 2
Dependent Claim
103 words
Apparatus of the character described comprising, a bed of a size sufficient to receive and support a hay stack; a conveyor on the bed; a vertical array of horizontally arranged toothed rolls rotatably mounted at one end of the bed, said array being of hay stack height and extending transversely substantially the width of the bed; a hay chopper at said end of the bed; means for rotating the rolls; means for operating the conveyor to feed a hay stack on the bed into the rolls to disintegrate the stack; and means for feeding hay disintegrated by the rolls into the hay chopper.
Claim 3
Dependent Claim
126 words
Apparatus of the character described comprising, a bed of a size sufficient to receive and support a hay stack; a conveyor on the bed; a vertical array of horizontally arranged toothed rolls rotatably mounted at one end of the bed, said array being of hay stack height and extending transversely substantially the width of the beD; a well extending transversely of and substantially the width of the bed positioned below the lowermost roll of said array; a hay chopper at said end of the bed; means for rotating the rolls; means for operating the conveyor to feed a hay stack on the bed into the rolls to disintegrate the stack; and means in the well for feeding hay disintegrated by the rolls into the hay chopper.
Claim 4
Dependent Claim
126 words
Apparatus of the character described comprising, a bed of a size sufficient to receive and support a hay stack; a conveyor on the bed; a vertical array of horizontally arranged toothed rolls rotatably mounted at one end of the bed, said array being of hay stack height and extending transversely substantially the width of the beD; a well extending transversely of and substantially the width of the bed positioned below the lowermost roll of said array; a hay chopper at said end of the bed; means for rotating the rolls; means for operating the conveyor to feed a hay stack on the bed into the rolls to disintegrate the stack; and means in the well for feeding hay disintegrated by the rolls into the hay chopper.
Claim 5
Dependent Claim
156 words
Apparatus of the character described comprising, a bed of a size sufficient to receive and support a hay stack; a conveyor on the bed; a vertical array of horizontally arranged toothed rolls rotatably mounted at one end of the bed, said array being of hay stack height and extending transversely substantially the width of the bed; a well extending transversely of and substantially the width of the bed positioned below the lowermost roll of said array; a rotatably mounted toothed drum positioned at said end of the bed; means for rotating the rolls, means for operating the conveyor to feed a hay stack on the bed into the rotating rolls to disintegrate the hay stack; a reverse-flighted auger in said well; means for rotating said auger to feed disintegrated hay to the center of the well and a discharge opening at the center of the well to permit passage of disintegrated hay to the toothed drum.
