Abstract
A clutch assembly for coupling a first spindle to a second spindle. The clutch assembly has a first disc connectable to the first spindle. A first finger is operatively coupled to the first disc and pivotable between a first engaged position and a first disengaged position. The first finger opposes rotation of the first disc in a first direction when the first finger is in the first engaged position. A second disc is connectable to the second spindle. The second disc pivots the first finger from the first engaged position to the first disengaged position when the second disc is rotated in the first direction through a first range of angular positions and rotates the first disk in the first direction when the second disc is rotated beyond the first range of angular positions.
