Abstract
Abstract A tool for inserting an electrical wire into a clip type terminal is described. The tool features a removable working blade which is also reversible to provide a cutting edge to remove excess wire. Cutting is effected by applying a controlled impulse to the blade via a bifurcated blade holding adaptor from an automatic impulse generator arranged in an elongated housing.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
126 words
A tool for inserting a wire into the slot of a clip-type terminal, comprising an elongated housing, an elongated impulse generating device within said housing and having a projecting plunger rod which is impacted when moved inward a preset distance, a working blade having opposed ends and a generally rectangular cross-section, at least one of said opposed ends having a slot and a recess extending into the blade from the slot bottom and dimensioned to receive the terminal end, and means for securing the blade at the other of its ends to the end of the projecting plunger rod in such manner that the blade one end projects from the housing, said housing containing a generally rectangular guideway for receiving the blade and preventing rotation thereof.
Claim 2
Dependent Claim
126 words
A tool for inserting a wire into the slot of a clip-type terminal, comprising an elongated housing, an elongated impulse generating device within said housing and having a projecting plunger rod which is impacted when moved inward a preset distance, a working blade having opposed ends and a generally rectangular cross-section, at least one of said opposed ends having a slot and a recess extending into the blade from the slot bottom and dimensioned to receive the terminal end, and means for securing the blade at the other of its ends to the end of the projecting plunger rod in such manner that the blade one end projects from the housing, said housing containing a generally rectangular guideway for receiving the blade and preventing rotation thereof.
Claim 3
Dependent Claim
31 words
A tool as set forth in claim 1 wherein an adaptor member is secured to the plunger rod end and comprises means for removably locking same to the blade other end.
Claim 4
Dependent Claim
40 words
A tool as set forth in claim 2 wherein the adaptor comprises a flattened shank portion adapted to seat in the blade end recess, said shank portion having a height such that the blade edges remain clear of the adaptor.
Claim 5
Dependent Claim
40 words
A tool as set forth in claim 3 wherein the adaptor comprises projecting tines of spring metal for engaging the blade end recess, said tines having outwardly enlarged lobe ends for engaging blade walls at the bottom of the recess.
Claim 6
Dependent Claim
39 words
A tool as set forth in claim 1 wherein in the housing is of generally tapered configuration from a wide end remote from the blade to a narrow end at the blade providing an unobstructed view of the terminal.
Claim 7
Dependent Claim
40 words
A tool as set forth in claim 1 wherein the blade other end also haS a slot and a recess extending from the slot bottom into the blade interior, both recesses terminating in a common hole in the blade side.
Claim 8
Dependent Claim
43 words
A tool as set forth in claim 6 wherein at said one end the blade walls defining the slot have flat edges, and at said other end the blade walls defining the slot have one flat edge and one slightly longer cutting edge.
Claim 9
Dependent Claim
31 words
A tool as set forth in claim 1 wherein the housing contains an interior wall portion separating the guideway from another cavity therein housing the remainder of the impulse generating device.
