Abstract: A general purpose rasp bar carrying rotor construction for an axial flow-type harvester combine embodying a vaned impeller and a series of bars which cooperate with elements within the surrounding rotor casing for crop threshing and grain separation purposes in a novel and efficient manner. The rotor proper is generally of imperforate tubular cylindrical construction so that the crop material in its entirety is confined to the annulus which exists between the rotor and its casing.

The threshing portion of the rotor having both helical and longitudinal extending rasp bars.

Abstract: A rethresher and conveyor for combines in which a rotary blower is positioned to receive tailings from a combine and in which a blower is provided with threshing elements coacting with stationary elements to rethresh the tailings. The rethreshed tailings are entrained in the air stream formed by the blower and conveyed from the rethreshing assembly through duct work to the combine for reprocessing.

Abstract: A self-propelled combine has a forward transversely elongated harvesting platform mounted on the forward end of a forwardly and downwardly inclined feeder housing through which the crop is fed to a separating mechanism in the combine body. A plurality of axially transverse paddle type impellers are mounted in the feeder housing and extend between the opposite sides of the housing immediately above the housing floor, the impellers being rotated in the same direction so that the impeller paddles move rearwardly along the floor, whereby the crop material is engaged by successive paddles and moved upwardly and rearwardly along the housing floor to the separating mechanism.

Abstract: Control means for the feeding of crop material from a header and condensing auger to the forward, inlet end of an upwardly and rearwardly extending elevator having an endless flight therein, said control means comprising plates connected to the inlet end of said elevator to restrict the width thereof and thereby prevent crop material from being engaged by the outer edges of said endless flight in said elevator, thereby preventing the accumulation and backfeeding of crop material along opposite side edges of said elevator.

Abstract: This invention comprises novel combine conveyor means having novel transverse slat or flight means adapted to engage and drag fresh cut unthreshed grain along at a uniform velocity and then eject the same at an increased velocity at an exit end of the conveyor means while the velocity of the conveyor means remains the same, and the transverse slat means being formed with recesses in grain engaging edge portion means thereof or formed with a plurality of trailing fingers for providing a stripping action on the grain as the grain is transferred from an auger to a conveyor and from the conveyor to a threshing cylinder.

Abstract: In an apparatus for increasing the yield of beans or grain wherein a primary harvesting machine or header is mounted forward of the combine with a secondary harvesting device located immediately to the rear of the primary harvester. The secondary harvesting device is vacuum operated to pick up beans or grain knocked to the ground under the primary harvester. The vacuumed up beans or grain are fed into the onboard chaffer and separator mechanism of the combine for cleaning and combining with the beans or grain picked up by the primary harvester.

Abstract: The harvesting mechanism of the present invention uses a transversely extending threshing means and a rotary separating mechanism. The separating mechanism includes a transversely extending separating rotor having crop treating and crop conveying elements cooperating with a separating concave operable to receive crop material from the threshing means and separate grain from the crop material while the material is being conveyed spirally to one end for discharge.

Abstract: A harvesting and threshing machine having a crop collecting platform carrying a threshing cylinder extending across its full crop collecting width. Crop threshed by the cylinder passes to a straw conveyor mounted behind the cylinder which collects the threshed crop and conveys it laterally. The straw conveyor may itself effect grain separation or may pass the crop to grain separation apparatus.

Abstract: In a combine having a header to cut crop material and an elevator to deliver the cut crop material to auger means in an undershot manner for feeding the same to threshing rotor of an axial flow combine, there is provided an adjustable transition or feed plate between the upper end of the elevator and the forward end of the rotor means to adapt the combine to accommodate crops of different types of texture, bulk, character and moisture content and prevent back-feeding of the crop material down the elevator. The adjustment is readily made manually and externally of the combine.

Abstract: Combined harvesting and threshing machine which can be mounted as a compact single unit on the front of a self-propelled power unit. Crop is cut by a cutterbar and fed by an auger to a threshing cylinder at one end of a crop gathering table. The threshing cylinder discharges threshed crop onto the input end of straw walkers mounted above the cutterbar.

Abstract: In a combine having a header to cut crop material and an elevator to deliver the cut crop material to auger means in an undershot manner for feeding the same to threshing rotors of an axial flow combine, there is provided an improved transition or feed plate between the upper end of the elevator and the forward end of the rotor means to postpone or delay the discharge of crop material by the rear discharging portion of the elevator until leading portions of the discharging crop material are at least partially engaged by the auger means whereby more positive control is maintained over the transfer of crop material from the elevator to the auger feeding means.
