Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 208 words
A rtool for fastening lines having an upper crimping head, a lower crimping head and means for forcing said upper and lower crimping heads together to deform a crimping sleeve, the improvement comprising means defining a plurality of first parallel grooves in said upper crimping head, means defining a like plurality of grooves in said lower crimping head adapted to mate and engage with said first grooves, means defining a third groove in said upper crimping head disposed generally perpendicular across said first grooves, the depth of said third groove being less than the depth of said first parallel grooves, means defining a fourth groove in said lower crimping head disposed generally perpendicular across said second grooves, the depth of said fourth groove being less than the depth of said second parallel grooves, said third and fourth grooves disposed opposite each other to define a channel through said first and second grooves when said upper and lower crimping heads are engaged, the width of said third and fourth grooves being less than the width of said crimping sleeve, with said first and second grooves adapted to engage and deform the opposite sides of said crimping sleeve when said crimping sleeve is aligned with said third and fourth grooves.
Claim 2
Dependent Claim 208 words
A rtool for fastening lines having an upper crimping head, a lower crimping head and means for forcing said upper and lower crimping heads together to deform a crimping sleeve, the improvement comprising means defining a plurality of first parallel grooves in said upper crimping head, means defining a like plurality of grooves in said lower crimping head adapted to mate and engage with said first grooves, means defining a third groove in said upper crimping head disposed generally perpendicular across said first grooves, the depth of said third groove being less than the depth of said first parallel grooves, means defining a fourth groove in said lower crimping head disposed generally perpendicular across said second grooves, the depth of said fourth groove being less than the depth of said second parallel grooves, said third and fourth grooves disposed opposite each other to define a channel through said first and second grooves when said upper and lower crimping heads are engaged, the width of said third and fourth grooves being less than the width of said crimping sleeve, with said first and second grooves adapted to engage and deform the opposite sides of said crimping sleeve when said crimping sleeve is aligned with said third and fourth grooves.
Claim 3
Dependent Claim 17 words
The tool as claimed in claim 1 wherein said first and second parallel grooves comprise triangular prisms.
Claim 4
Dependent Claim 15 words
The tool as claimed in claim 1 wherein said third and fourth grooves are semi-cylindrical.
