Patent ID: 7226355

Claim:
A transverse pivot assembly mechanism for automatically positioning a pinch-point of a concave relative to a rotor of a combine, the mechanism comprising: a linking assembly pivotally coupling said concave to said combine, said linking assembly defining at least one transverse pivot axis, said transverse pivot axis allowing automatic transverse pivot of said concave relative to said rotor in accordance with adjustably set clearance spacing between said concave and said rotor, wherein said linking assembly includes at least one non-rotatable member defining a peripheral surface, at least one rotatable member defining a peripheral surface, a rotatable shaft, and at least one linking member, wherein said non-rotatable member is mounted to said concave and said rotatable member is mounted to said rotatable shaft for rotation therewith, said peripheral surface of said rotatable member being engageable with said peripheral surface of said non-rotatable member, said linking member coupling at least one of said non-rotatable member and said concave with at least one of said rotatable shaft and said rotatable member.
