Abstract
Abstract A grip for wires and cables for use by linemen when applying tension to such wires and cables during installation thereof. The grip includes a rigid housing that defines a laterally accessible pathway for the wire. Wire engaging jaws are disposed on opposite sides of the pathway for movement toward the pathway so as to grip a wire residing therein. One jaw is supported on a four bar linkage arrangement that maintains the jaw surface in parallelism with the pathway. Associated with such jaw is a bail to which tension is applied when pulling the wire so that the force on the wire is proportional to the tension applied to the bail. The other jaw is wedge shaped and the housing has a diverging bearing surface so that movement of the second jaw along the surface moves the wire gripping portion of the second jaw into engagement with wire in the pathway. The second jaw is provided in a variety of sizes so that one grip can be used on a wide range of wire diameters. The mounting for the first jaw includes a spring for biasing the first jaw away from the wire pathway and a cam member for positioning the first jaw against the force of the spring so that the grip will remain on the wire in the absence of tension and until intentionally dislodged by movement of the cam.

Claim 1
Independent Claim
332 words
A wire grip for applying tension to a piece of wire in a given direction axially of the wire comprising a rigid housing defining an elongate wire receiving laterally accessible pathway therein, said housing including first and second channels confronting one another across said pathway, a first jaw member disposed in said first channel, said first jaw member having a wire engaging surface, means for mounting said first jaw member for movement toward and away from said pathway while retaining said wire engaging surface in parallelism with said pathway, said mounting means acting to constrain said first jaw member for composite movement toward said given direction and into said pathway, and a second jaw member disposed in said second channel, said second jaw member having a wire engaging surface, means supporting said second jaw member so that the wire engaging surface thereof confronts in parallelism the wire engaging surface of said first jaw member, said supporting means including means for constraining said second jaw member for composite movement opposite said given direction and into said pathway, a bail for affording engagement of said first jaw member for applying tension thereto in said given direction, means for resiliently biasing said first jaw member in a composite direction opposite said given direction and away from said pathway, said bail being arranged so that tension applied thereto acts against said biasing means, means for affording pivotal movement of said bail relative said first jaw member between a pull position at which said bail is generally parallel to said pathway, and a release position at which said bail is oblique of said pathway, said bail having a camming surface adjacent said pivotal movement affording means and eccentric thereof, said housing having a surface abutting said camming surface and cooperating therewith so that the wire engaging surface of said first jaw member is in said pathway when said bail is in said pull position and remote from said pathway when said bail is in said release position.
Claim 2
Dependent Claim

A wire grip for applying tension to a piece of wire in a given direction axially of the wire comprising a rigid housing defining an elongate wire receiving laterally accessible pathway therein, said housing including first and second channels confronting one another across said pathway, a first jaw member disposed in said first channel, said first jaw member having a wire engaging surface, means for mounting said first jaw member for movement toward and away from said pathway while retaining said wire engaging surface in parallelism with said pathway, said mounting means acting to constrain said first jaw member for composite movement toward said given direction and into said pathway, and a second jaw member disposed in said second channel, said second jaw member having a wire engaging surface, means supporting said second jaw member so that the wire engaging surface thereof confronts in parallelism the wire engaging surface of said first jaw member, said supporting means including means for constraining said second jaw member for composite movement opposite said given direction and into said pathway, a bail for affording engagement of said first jaw member for applying tension thereto in said given direction, means for resiliently biasing said first jaw member in a composite direction opposite said given direction and away from said pathway, said bail being arranged so that tension applied thereto acts against said biasing means, means for affording pivotal movement of said bail relative said first jaw member between a pull position at which said bail is generally parallel to said pathway, and a release position at which said bail is oblique of said pathway, said bail having a camming surface adjacent said pivotal movement affording means and eccentric thereof, said housing having a surface abutting said camming surface and cooperating therewith so that the wire engaging surface of said first jaw member is in said pathway when said bail is in said pull position and remote from said pathway when said bail is in said release position.
Claim 3
Dependent Claim
26 words
A wire grip according to claim 1 including a stop member on said first jaw member for prohibiting movemeNt of said bail beyond said pull position.
Claim 4
Dependent Claim
39 words
A wire grip according to claim 2 wherein said camming surface has a portion for cooperation with said abutting housing surface that positions said first jaw member in an install position intermediate said pull position and said release position.
Claim 5
Dependent Claim
62 words
A wire grip according to claim 3 wherein said housing adjacent said abutting surface has a visible index marker and wherein said bail adjacent said camming surface has index markers corresponding respectively to said pull position, said install position, and said release position so as to afford a precise visual indication of the position of said bail and said first jaw member.
Claim 6
Dependent Claim
34 words
A wire grip according to claim 1 wherein said second jaw member is replaceable whereby a plurality of different size second jaw members can be employed to accommodate a wide range of wire sizes.
