First Claim
Patent Images
1. A cable and rod gripping apparatus, comprising:
- (a) a base;
(b) a pair of linkages each pivotally mounted on said base with spaced apart pivot axes that are parallel and located at respective pivot ends of said linkages; and
(c) a gripping pad pivotally mounted on a distal end of each of said linkages remote from the pivot end with a gripping pad pivot axis oriented in a direction parallel to the pivot axes of said linkages, said linkages pivotal from a position in which said linkages are aligned and said gripping pads are remote from each other to a position in which said linkages are aligned or nearly aligned and said gripping pads are in contact with or in close proximity to each other, said gripping pads contacting said cable or said rod just before reaching a position of alignment of said linkages and upon engagement of said gripping (d) pads with said cable or rod, tensioning said cable or pulling on said rod in a direction tending to bring said linkages into alignment increases friction between said gripping pads and said cable or rod.

Abstract
A cable and rod gripping apparatus which includes a base, a pair of linkages pivotally mounted on said base and a gripping pad pivotally mounted on a distal end of each of said linkages in opposition to each other so that upon pivoting together the pads contact the cable or the rod above a position of alignment of the linkages and move together until gripping said cable or rod while still above the position of alignment.
