Abstract
Abstract A wire-cutting tool has a pair of swingably interconnected plier arms and a holding member swingable jointly with one of these arms, this holding member including a rear portion traversed by the pivotal plier axle and rigid with the shank of the associated arm, an inclined front portion substantially coextensive with a sloping face on the jaw of that arm, and a substantially triangular intermediate portion which is perpendicular to the swing plane and overlies a transverse land of the arm. Upon the cutting of a wire, a straight edge of the front portion of the holding member normally registering with the cutting edge of the underlying jaw is repressed by the cut-off wire end and rides up the sloping jaw face against the torsional resistance of the triangular intermediate portion of the holding member.

Claim 1
Independent Claim
207 words
In a wire-cutting tool including a pair of plier arms interconnected for relative rotation in a swing plane about a pivotal axle, said arms having rearwardly extending shanks and forwardly extending jaws with sloping faces which terminate in respective cutting edges meeting along a straight line in a closure position, and a holding member secured to one of said arms for joint swinging to grip a cut-off wire end between itself and the opposite jaw upon closure of said jaws, the improvement wherein said holding member is a flat integral resilient strip longitudinally subdivided into three portions, namely: a rear portion parallel to said swing plane traversed by said pivotal axle and rigidly anchored rearwardly of said axle to the shank of said one of said arms; a substantially triangular intermediate portion perpendicular to said swing plane overlying a transverse land of said one of said arms adjoining the sloping face thereof; and an inclined front portion substantially coextensive with said sloping face of said one of said arms and overlying same with limited relative slidability against the torsional resistance of said intermediate portion, said front portion having a straight edge extending along substantially the full length of the cutting edge of sAid one of said arms.
Claim 2
Dependent Claim
207 words
In a wire-cutting tool including a pair of plier arms interconnected for relative rotation in a swing plane about a pivotal axle, said arms having rearwardly extending shanks and forwardly extending jaws with sloping faces which terminate in respective cutting edges meeting along a straight line in a closure position, and a holding member secured to one of said arms for joint swinging to grip a cut-off wire end between itself and the opposite jaw upon closure of said jaws, the improvement wherein said holding member is a flat integral resilient strip longitudinally subdivided into three portions, namely: a rear portion parallel to said swing plane traversed by said pivotal axle and rigidly anchored rearwardly of said axle to the shank of said one of said arms; a substantially triangular intermediate portion perpendicular to said swing plane overlying a transverse land of said one of said arms adjoining the sloping face thereof; and an inclined front portion substantially coextensive with said sloping face of said one of said arms and overlying same with limited relative slidability against the torsional resistance of said intermediate portion, said front portion having a straight edge extending along substantially the full length of the cutting edge of sAid one of said arms.
Claim 3
Dependent Claim
24 words
The improvement defined in claim 1 wherein said straight edge lies flat against the sloping face of said opposite jaw in said closure position.
Claim 4
Dependent Claim
37 words
The improvement defined in claim 1 wherein said shanks are partly covered by insulation, said rear portion being anchored to the shank of said one of said arms by having an extremity enveloped by the insulation thereof.
