Abstract
A wire gripping assembly is provided with a pair of lever arms that are each movable between a gripping position and a release position. Each lever arm includes a plurality of engagement teeth that interact with drive teeth formed on a moving rack member. The rack member is coupled to a piston movable within an open interior of a drive cylinder. Pressurized air is supplied to either side of the piston to move the piston and rack member. The movement of the piston and the rack member within the drive cylinder results in pivoting movement of the first and second lever arms between the gripping position and the release position.
