Abstract:
1. A clutch assembly for coupling a first spindle to a second spindle, the clutch assembly comprising: a first disc connectable to the first spindle and rotatable about a first axis, the first disc having a first couple; a first finger operatively coupled to the first disc and pivotable about a second axis between a first engaged position and a first disengaged position, the second axis spaced from and parallel to the first axis, the first finger configured to oppose rotation of the first disc in a first direction when the first finger is in the first engaged position; and a second disc connectable to the second spindle, the second disc having a first slot engaged by the first couple, the second disc configured to pivot 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 to rotate the first disc in the first direction when the second disc is rotated beyond the first range of angular positions, wherein the first disc has a first contact, and the first finger has a first stop spaced a first radius from the second axis and configured to apply to the first contact a reactive force opposing rotation of the first disc in the first direction when the first finger is in the engaged position.
