Abstract
Abstract A hand tool wraps a wire about a terminal, having a slot for receiving the wire. Embodied in the tool is a hollow-nosed shank where the nose has an oblique slot and an indentation, diametrically opposed to each other, for initially contacting the wire after placing the shank over the terminal to provide a perpendicular orientation of the tool with the wire. During the wrapping operation lobes on the nose of the shank ride over the wire to impart a helical wrap of wire about the terminal.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
194 words
In a tool for wrapping a wire about a terminal wherein the wire extends transversely on opposite sides of the terminal: a sleevelike shank for receiving the terminal; said shank having an oblique slot extending inward from a peripheral edge for receiving a free end section of the wire which extends on one side of the terminal; said shank having an indentation on the peripheral edge, diametrically opposed and of equal depth as the slot for contacting a section of the wire on the opposite side of the terminal to orient said shank perpendicular to the wire; said shank having a symmetrical pair of axially extending curved ridges disposed on diametrically opposite sides of the periphery interposed between the slot and the indentation for imparting a camming action to the shank; and means for rotating said shank about the terminal to engage the wire in said indentation whereafter further rotation of said shank wraps a convolution of wire about the terminal, while the pair of opposed ridges impart equal axial motion to said shank during the rotation to produce an axial displacement that results in an inherent helical wrapping of wire around the terminal.

Dependent Claim

In a tool for wrapping a wire about a terminal wherein the wire extends transversely on opposite sides of the terminal: a sleevelike shank for receiving the terminal; said shank having an oblique slot extending inward from a peripheral edge for receiving a free end section of the wire which extends on one side of the terminal; said shank having an indentation on the peripheral edge, diametrically opposed and of equal depth as the slot for contacting a section of the wire on the opposite side of the terminal to orient said shank perpendicular to the wire; said shank having a symmetrical pair of axially extending curved ridges disposed on diametrically opposite sides of the periphery interposed between the slot and the indentation for imparting a camming action to the shank; and means for rotating said shank about the terminal to engage the wire in said indentation whereafter further rotation of said shank wraps a convolution of wire about the terminal, while the pair of opposed ridges impart equal axial motion to said shank during the rotation to produce an axial displacement that results in an inherent helical wrapping of wire around the terminal.
Claim 3
Dependent Claim
181 words
In a hand operated tool for wrapping a wire about a terminal having a wire-receiving hole therein: a handle; a cylindrical shank secured to said handle, said shank having a hollow nose end for insertion of the terminal with a wire extending transversely through the wire-receiving hole; said shank having a slot extending at an oblique angle from a forward edge of said hollow nose end for engaging and seating a section of the wire at the bottom of said slot; said shank having an indentation extending from said edge at a point diametrically opposed to said slot for contacting another section of the wire to orient said shank in a perpendicular direction with respect to the wire; and a pair of symmetrical curved ridges axially extending from diametrically opposite sides of said shank and interposed between said slot and said indentation for imparting a camming action against the wire during rotation of said handle to impart equal axial motion to said shank to seat a portion of the wire in said slot, and helically wrap the wire about the terminal.
