ABSTRACT:
A variable ratio, or adjustable ratio, mechanical drive mechanism employs a rotatable driving element the effective diameter of which may be changed. The driving element is segmented to permit effective diameter change by an alteration in the relative position of the segments.
Alteration is effected by forcing a change in the separation of the axis of driving element and the point of engagement of the driving element with the driven element.
