Abstract
Abstract A hand tool for loosening coiled wire wrap electrical connections by engaging the end of the wire wrap, rotating the wrap in a loosening direction and then lifting the loosened wrap off from the terminal pin. For reinstalling the coil of wire, the procedure is reversed with a pair of collet jaws being squeezed together at intervals to form the coil wrap back into position on the terminal.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
152 words
A hand tool for removing and replacing coiled wire wrap electrical connections comprising: a hollow tubular housing having first and second pair of opposing in-line longitudinally extending slots parallel to the axis of said housing; a hollow tubular spindle slidably engaged in said housing and having a semi-helical slot adapted to engage the end of a coil wire wrap electrical connection when the terminal about which the coil of wire is wrapped is received in the axial opening of said spindle; a knob attached to said spindle at the opposite end from said semi-helical slot; a pair of collet members slidably engaged in said first and second slots of the housing for crimping a coiled wire which has been replaced on a terminal; and a hollow retaining sleeve inserted co-axially between said housing and said spindle for retaining said collet members in the first and second pair of slots in said housing.
Claim 2
Dependent Claim
152 words
A hand tool for removing and replacing coiled wire wrap electrical connections comprising: a hollow tubular housing having first and second pair of opposing in-line longitudinally extending slots parallel to the axis of said housing; a hollow tubular spindle slidably engaged in said housing and having a semi-helical slot adapted to engage the end of a coil wire wrap electrical connection when the terminal about which the coil of wire is wrapped is received in the axial opening of said spindle; a knob attached to said spindle at the opposite end from said semi-helical slot; a pair of collet members slidably engaged in said first and second slots of the housing for crimping a coiled wire which has been replaced on a terminal; and a hollow retaining sleeve inserted co-axially between said housing and said spindle for retaining said collet members in the first and second pair of slots in said housing.
Claim 3
Dependent Claim
44 words
A hand tool according to claim 1 wherein said spindle has an oppositely inclined semi-helical slot in either end and said knob is detachable whereby the spindle may be reversed to accommodate either right hand or left hand wound coil wire wrap electrical connections.
Claim 4
Dependent Claim
44 words
A hand tool according to claim 2 wherein said pair of collet members has ears extending laterally from said first pair of slots and jaws engaged in saiD second pair of slots; said ears and jaws being connected by a flexible strip of metal.
Claim 5
Dependent Claim
51 words
A hand tool according to claim 3 wherein said second pair of slots has a downwardly inclined surface at one end and said collet jaws have a rounded cam surface which bears against said inclined surface when a downward pressure is exerted on said collet ears forcing said collet jaws inward.
Claim 6
Dependent Claim
45 words
A hand tool according to claim 4 including a pair of springs in each of said first slots which applies a light downward pressure on said collet ears whereby said collet jaws grip the coil wire wrap when the tool is positioned over the terminal.
