<p>A clutch (10) selectively transmits torque and rotary motion from a spindle (12) having an axis of rotation to a drum (16). First and second shoe members (30, 32) disposed radialy between the spindle (12) and the drum (16) move radially with respect to the axis of rotation between an engaged position and a disengaged position with respect to the drum (16). The first and second shoe members (30, 32) are responsive to acceleration for moving into the engaged position and responsive to rotational speed for moving into the disengaged position. A biasing spring (24) normally maintains the first and second shoe members (30, 32) in the disengaged position when the spindle (12) is at rest.</p> |
