Abstract
Abstract A grip for pulling fiber optic cable having a wire mesh sleeve for engaging the outer jacket of the cable and a coupling assembly for engaging the strength member in the cable. The grip comprises a hollow member, a pulling eye at the lead end of the hollow member, a wire mesh sleeve at the tail end of the hollow member, and a coupling assembly attached to the hollow member. The hollow member forms a protective sheath supporting the coupling assembly therein. This coupling assembly can be a loop, a bore and a plug assembly or a plurality of set screws.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
143 words
A grip for pulling fiber optic cable including an optical fiber core, a strength member located adjacent the core and an outer jacket enclosing the strength member with an exposed end of the strength member extending therefrom, the combination comprising: a hollow member having a lead end and a tail end and an inner surface; a pulling eye coupled to said hollow member lead and; a wire mesh sleeve coupled to said hollow member at said tail end thereof and adapted to receive the fiber optic cable therein and grip the outer jacket thereof; and coupling means, coupled to said hollow member, for coupling the exposed end of the strength member to said hollow member for increased support during pulling, said coupling means comprising means for releasably clamping the strength member directly against said inner surface and under an outwardly directed clamping force.
Claim 2
Dependent Claim
143 words
A grip for pulling fiber optic cable including an optical fiber core, a strength member located adjacent the core and an outer jacket enclosing the strength member with an exposed end of the strength member extending therefrom, the combination comprising: a hollow member having a lead end and a tail end and an inner surface; a pulling eye coupled to said hollow member lead and; a wire mesh sleeve coupled to said hollow member at said tail end thereof and adapted to receive the fiber optic cable therein and grip the outer jacket thereof; and coupling means, coupled to said hollow member, for coupling the exposed end of the strength member to said hollow member for increased support during pulling, said coupling means comprising means for releasably clamping the strength member directly against said inner surface and under an outwardly directed clamping force.
