Abstract
Abstract Corn detasseling apparatus for mounting on a vehicle frame to be moved thereby to a field of corn and detassel the same. The apparatus includes a pair of cleated tires in engagement with each other and driven in opposite directions so as to define a tassel receiving nip which may receive the tassel on a stalk of corn and move the same upwardly to pull it from the corn plant.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
142 words
A corn detasseling head comprising: a base; a pair of shafts on said base, said shafts being parallel and projecting upwardly and forwardly of said base; a pair of cylindrical elements, each mounted on a respective one of said shafts for rotation about its cylindrical axis relative to said base, the cylindrical surfaces of said cylindrical elements being in contact with each other to define a detasseling nip; cleat means on each of said cylindrical elements adjacent the cylindrical surfaces thereof, said cleat means including a plurality of protuberances on each cylindrical element and spaced uniformly about the cylindrical axis thereof to project outwardly from the cylindrical periphery thereof, the protuberances of one of said cylindrical elements meshing in gear-like fashion with the protuberances of the other cylindrical element; and means for oppositely rotating said cylindrical elements about their respective cylindrical axes.
Claim 2
Dependent Claim
142 words
A corn detasseling head comprising: a base; a pair of shafts on said base, said shafts being parallel and projecting upwardly and forwardly of said base; a pair of cylindrical elements, each mounted on a respective one of said shafts for rotation about its cylindrical axis relative to said base, the cylindrical surfaces of said cylindrical elements being in contact with each other to define a detasseling nip; cleat means on each of said cylindrical elements adjacent the cylindrical surfaces thereof, said cleat means including a plurality of protuberances on each cylindrical element and spaced uniformly about the cylindrical axis thereof to project outwardly from the cylindrical periphery thereof, the protuberances of one of said cylindrical elements meshing in gear-like fashion with the protuberances of the other cylindrical element; and means for oppositely rotating said cylindrical elements about their respective cylindrical axes.
Claim 3
Dependent Claim
33 words
A corn detasseling head according to claim 1 wherein said cylindrical elements are defined by inflatable tires and said protuberances are at the junction of the tire side walls and the fire tread.
Claim 4
Dependent Claim
51 words
A corn detasseling head according to claim 1 further including means for securing said base to the front of a wheeled vehicle such that said shafts project forwardly of the vehicle and upwardly therefrom at an angle in the range from about 40* to about 50* with respect to the horizontal.
Claim 5
Dependent Claim
19 words
A corn detasseling head according to claim 3 further including means for selectively varying said angle within said range.
Claim 6
Dependent Claim
72 words
A corn detasseling head according to claim 3 wherein said base includes a horizontally elongated member and said securing means includes a parallelogram linkage whereby the vertical position of said cylindrical elements with respect to a vehicle to which they may be secured may be varied without changing their attitude with respect thereto; and motor means operatively associated with said parallelogram linkage for selectively varying said vertical position of said cylindrical elements.
Claim 7
Dependent Claim
33 words
A corn detasseling head according to claim 5 wherein said cylindrical elements are defined by inflatable tires and said protuberances are at the junction of the tire side walls and the tire tread.
Claim 8
Dependent Claim
61 words
The corn detasseling head of claim 1 wherein said rotating means includes a motor drivingly engaging one of said shafts to rotate the same to thereby drive the cylindrical element; the other cylindrical element being driven in the opposite direction by reason of the meshing of the cleat means thereof with the cleat means of the other of said cylindrical elements.
