Abstract
Abstract A hand tool for loosening and removing coiled wire wrap electrical connections by engaging the end of a wire and rotating the tool until the wire loosens and can be lifted off. The tool has a hollow central tubular member with a helical thread on one end. A second tubular member having flexible collet jaws fits over the center tube for replacing coil wire wraps. An outer tubular member fits over the second tubular member and when pushed down forces the collet jaws against the wire wrap to tighten the coil.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
101 words
A tool for removing and replacing coil wire wraps comprising: a first tubular member having a raised external helical groove having a predetermined depth at one end; a second tubular member concentric with the first tubular member and having at least one flexible collet jaw at one end adjacent to the helical groove of the first tubular member; a third tubular member slidable over and concentric with the second tubular member to force the collet jaw of the second tubular member against the helical groove of the first tubular member whereby a coil wire wrap may be retained in the tool.
Claim 2
Dependent Claim
101 words
A tool for removing and replacing coil wire wraps comprising: a first tubular member having a raised external helical groove having a predetermined depth at one end; a second tubular member concentric with the first tubular member and having at least one flexible collet jaw at one end adjacent to the helical groove of the first tubular member; a third tubular member slidable over and concentric with the second tubular member to force the collet jaw of the second tubular member against the helical groove of the first tubular member whereby a coil wire wrap may be retained in the tool.
Claim 3
Dependent Claim
25 words
The tool as recited in claim 1 wherein the first concentric tubular member has a semi-helical slot in the opposite end from the helical groove.
Claim 4
Dependent Claim
31 words
The tool as described in claim 2 including longitudinal slots in said second tubular member; and a retaining pin passing through the first tubular member and riding in the longitudinal slots.
Claim 5
Dependent Claim
34 words
The tool as recited in claim 3 wherein the collet jaw is formed of a plurality of flexible strips at the end of the second tubular member with resilient pads attached to the strips.
Claim 6
Dependent Claim
50 words
The tool as recited in claim 3 wherein the collet jaw is comprised of a flexible semi-circular strip attached to the outside of said second tubular member with a rounded post attached to the concave surface of the flexible strip adjacent to the helical groove of the first tubular member.
Claim 7
Dependent Claim
39 words
The tool as recited in claim 1 wherein the helical groove has a depth slightly larger than the diameter of the wire for which the tool is intended to be used to prevent excessive pressure when rewrapping a coil.
