Patent ID: 7371162

Claim:
A mechanism for adjusting opening sizes of first and second sieve segments disposed in edge to edge relation along a first axis in an agricultural combine, comprising: a first adjusting element disposed along the first axis of the first sieve segment and rotatable about the first axis for adjusting the opening size of the first sieve segment; a second adjusting element disposed along the first axis of the second sieve segment and rotatable about the first axis for adjusting the opening size of the second sieve element; an actuating element in connection with the first adjusting element and operable for moving the first adjusting element in rotational movement about the first axis; and first and second connecting elements disposed in connection with the first and second adjusting elements, respectively, the connecting elements being connectable for connecting the first and second adjusting elements together such that the rotational movement of the first adjusting element in the will cause joint rotational movement of the second adjusting element, and the connecting elements being disconnectable for allowing rotational movement of the first adjusting element about the first axis without causing rotational movement of the second adjusting element about the first axis.
