Abstract: A sieve assembly for combine includes a frame having side frame and divider members, a wire rotatably supported and extending transversely between the side and divider members. The wire has a majority portion and offset portion and at least one slat mounted thereon including a first pocket for removably receiving the major portion of the wire and a deflectable finger for positively locking the major portion of the wire into the first pocket to prevent accidental displacement of the slat from the wire. The slat includes a second pocket for removably receiving the offset portion of the wire to prevent rotational movement of the wire relative to the slat. In one embodiment, the side frame and divider members have circular apertures through which the wires extend. The inside diameter of these apertures are approximately the same, but slightly larger than, the outside diameter of the wire.

Abstract: An improved harvester pickup reel tine and bat structure results in light weight, ease of assembly and non-snagging operation. A one-piece tine and attachment is formed by molding a plastic tine integral with a split ring to clamp it onto the support tube. A single split in the ring and the integral construction permits an assembly with no protrusions on the rear surface of the reel which otherwise catches on accumulated material in the harvester. An alternate embodiment includes extension wings which interlock with adjacent structures to form a continuous bat thus affording the reel assembly which is convertible between a structure with or without bats.

Abstract: An adjustment means for the slats of sieves and chaffers comprising a manually operable screw mounted on a mounting plate fixed to the chaffer frame and directly connected with the conventional slotted bar for oscillating the slats to clean them and for setting their operating angular position, the screw being normally held on the mounting plate against non-rotative axial movement but releasable for back and forth axial movement to open and close the slats for cleaning purposes; the mounting plate including a latch adapted to engage a noncircular element fixed on the screw to prevent its inadvertent rotation, whereby after being released for operating the slats without rotation the screw is returned to the mounting plate for engagement of the latch, the slats will be positioned precisely in their initially set operating position.

Abstract: A controller for maintaining pick-up tines on harvesting reels at predetermined orientation in space as the reel is rotated for severing crops from the ground having inherent structural self-compensation for wear and dimensional tolerance stack-up in the assembly of parts thereof and induced reduction of peak loads thereon by means of a pendulously-suspended control spider which is pivotally mounted on the machine in the direction against and nominally on the line of action of the applied load on said spider from the gathering and cutting of crops by the pick-up reel of said machine.
