Abstract: A pickup reel is provided with an anti-wrap extension that can be easily mounted to one of the elongated tubes. The anti-wrap extension increases the size of the bat to prevent wrapping. The tine is provided with an upstanding projection having a mounting screw for securing the anti-wrap extension to the tine. In addition, the extension is provided with a downwardly projecting flange having mounting apertures into which the tines are inserted.

Abstract: A reel for a harvesting machine includes a plurality of circumferentially spaced radially extending support arms, a plurality of axially extending bat tubes rotatably supported on the outer end portions of the support arms, a plurality of axially spaced tines, preferably made from a synthetic thermoplastic or thermosetting material, mounted on each bat tube and a spring having one end connected to each bat tube and a support carried by the reel. The spring holds the bat tube in an operating position where the tines are at a predetermined angular orientation relative to the rotational axis of the reel during normal operation. If one or more tines on one bat tube engages a plug of wet hay or other obstruction, the spring permits the bat tube to rotate in a direction opposite to the rotational direction of the reel to a deflected position where the tine(s) can ride over the obstruction.

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: A snap-away auxiliary tine for harvester reels. The tine is attached to its supporting shaft by a split cylinder which partially encloses a shaft fitting. Rounded axial grooves in the inside of the split cylinder interlock with splines on the shaft fitting and prevent normal rotation of the tine. Extreme force on the tine, such as that when the tine hits a hard object, causes the split cylinder to spread slightly, disengage the grooves and rotate on the shaft, thus preventing tine breakage. Manual rotation repositions the tine.
