Interrupted infeed flight means for combine rotor

A rotor for an axial flow type mobile combine having threshing means extending longitudinally therealong rearwardly from the forward end thereof and including rasp bars and the like, in combination with flight means on the forward infeed end of said rotor operable to engage harvested agricultural material delivered thereto from the forward end of a combine, said flight means comprising interrupted flight segments arranged in a substantially spiral overall pattern and connected to a base member coaxial with said rotor, said interrupted segments being in axially offset and staggered relationship to each other by being longitudinally and circumferentially spaced along the surface of said base member from the forward end thereof toward the rearward end of said rotor to provide a substantial multiplicity of leading edges to attack the material aggressively, said rotor being operable for unidirectional rotation and the leading ends of said segments in the direction of rotation of said rotor being adapted to aggressively engage said agricultural material in a ripping and tearing manner to disintegrate any knotted masses thereof and thereby feed the same in a relatively even manner longitudinally rearward for engagement by the threshing means on said rotor.
