Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
111 words
In a wire inserting tool comprising a housing, an impulse generator within the housing, and a working blade having one end proximal to the impulse generator to receive an impulse and an opposite end distal from the impulse generator and projecting from the housing and having a recess for accommodating a wirereceiving terminal which blade serves for severing and seating the wire in the terminal, the improvement comprising the blade distal end having a channel, a separable tip member having at one end a cutting edge, and means for removably mounting the tip member to the blade at the channel to form between the channel and the tip the terminal-accomodating recess.
Claim 2
Dependent Claim
111 words
In a wire inserting tool comprising a housing, an impulse generator within the housing, and a working blade having one end proximal to the impulse generator to receive an impulse and an opposite end distal from the impulse generator and projecting from the housing and having a recess for accommodating a wirereceiving terminal which blade serves for severing and seating the wire in the terminal, the improvement comprising the blade distal end having a channel, a separable tip member having at one end a cutting edge, and means for removably mounting the tip member to the blade at the channel to form between the channel and the tip the terminal-accomodating recess.
Claim 3
Dependent Claim
52 words
A tool as claimed in claim 1 wherein the blade channel is defined by a bottom wall and opposed side walls, and the tip member mounting means comprises grooves in the channel side walls, the tip member having along opposed edges projections shaped to mate with and engage the channel side-wall grooves.
Claim 4
Dependent Claim
14 words
A tool as claimed in claim 2 wherein the channel side-wall grooves are V-shaped.
Claim 5
Dependent Claim
21 words
A tool as claimed in claim 2 wherein the channel side-wall grooves and tip member edge projections form a dovetail-type joint.
Claim 6
Dependent Claim
19 words
A tool as claimed in claim 2 and further comprising means for locking the tip member to the blade.
Claim 7
Dependent Claim
42 words
A tool as claimed in claim 5 wherein the tip locking means comprises a flat spring member secured to the blade and having a distal end configured to extend within the blade channel and latchingly-engage a recess in the tip member surface.
Claim 8
Dependent Claim
65 words
A tool as claimed in claim 6 wherein the tip member has at its opposite end a flattened edge, and at its surface two transverse crevices each for engaging the spring distal end when the tip member is mounted in one of two reversed positions on the blade, a portion of the spring member extending outwardly of the blade for unlatching of the tip member.
Claim 9
Dependent Claim
49 words
A tool as claimed in claim 7 wherein the blade extends within a guideway in the housing, the impulse generator is provided with an adaptor having a ball retainer end, and the blade proximal end is configured to resiliently engage and connect to the ball retainer of the adaptor.
Claim 10
Dependent Claim
36 words
A tool as claimed in claim 8 wherein a portion of the spring member extends outwardly from the blade within the guideway and bears against the guideway wall to firmly hold the blade within the guideway.
