MACHINE FOR HARVESTING SUGAR CANE
First Claim
1. In a machine for harvesting sugar cane the improvement which comprises a ground gliding member, yieldable means for mounting said member in position to glide over the ground, a plurality of cutters, means for mounting and rotating said cutters adjacent the bottom of said ground gliding member for cutting the cane, a stripping column, means for blowing air through said column, means for conveying the cane after it has been cut, said conveying means being adapted to feed the cut cane into said airblast column for stripping and a cutter for cutting the cane into pieces before it is fed into said airblast column.

Abstract
A machine to harvest sugar cane comprising a cutting disk to cut the standing cane. The disk is mounted on a convex shaped member gliding on the ground. A chain assembly seizes the cut cane to lead it between two belts which introduce it in an airblast column. At the entry of the airblast column, the cut cane is sliced sideways in the sense of movement of the cane. In the airblast column the cane is stripped and then loaded in a pick-up cart while the wastes are left on the ground.

2. A machine for harvesting sugar cane as specified in claim 1 wherein said ground gliding member is mounted on the same center as said plurality of cutters and wherein said member is free to rotate relative to said yieldable mounting means.
-
3. A machine for harvesting sugar cane as specified in claim 1 wherein said yieldable means for mounting said ground gliding member include an arm pivotally mounted on the chassis by means of a jack having a compressed air reservoir of sufficient volume with respect to that of the jack so that the action of support of the jack is appreciably the same in any position into which the arm pivots.
-
4. A machine for harvesting sugar cane as specified in claim 1 wherein said means for mounting and rotating the plurality of cutters are adapted to yield and follow the movement of the ground gliding member as it travels over the ground and wherein the cutters each have horizontal cutting portions that extend radially out from the edge of the gliding member.
-
5. A machine for harvesting sugar cane as specified in claim 4 wherein said means for mounting and rotating the plurality of cutters include a rotating disk and pivotal means for mounting each cutter including springs adapted to maintain said knives in radial position.
-
6. A machine for harvesting sugar cane as specified in claim 1 wherein said conveying means include plates of a compressible elastic material which assist in conveying the cane.
-
