ABSTRACT:
A first member is pivotally connected to a second member. A rigid support and a linking member are pivotally connected to one another and interconnected between the first member and the second member. The length of the rigid support is selectively adjustable at a constant rate. Adjustment of the length of the rigid support within a first range of length causes the second member to pivot at a first angular velocity relative to the first member. Adjustment of the length of the rigid support within a second range of length causes the second member to pivot at a second, relatively greater angular velocity relative to the first member.
