Abstract

Abstract A cut-clinch mechanism with a movable knife that is arranged to be slidably attached to a piston rod so that when the cutting edge of the knife engages a lead-in wire, a sensor will be contacted to indicate the lead-in wire is in a proper position for cutting and clinching.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 68 words
A cut-clinch mechanism including a fixed knife and a movable knife and means to drive said movable knife into cutting relationship with said fixed knife, the improvement which comprises: means linking said movable knife to said drive means, said linking means allowing a limited movement of said movable knife relative to said drive means and sensing means to determine if said movable knife has achieved said limited movement.
Claim 2
Dependent Claim 68 words
A cut-clinch mechanism including a fixed knife and a movable knife and means to drive said movable knife into cutting relationship with said fixed knife, the improvement which comprises: means linking said movable knife to said drive means, said linking means allowing a limited movement of said movable knife relative to said drive means and sensing means to determine if said movable knife has achieved said limited movement.
Claim 3
Dependent Claim 89 words
A cut-clinch mechanism including a fixed knife and a movable knife and means to drive said movable knife into cutting relationship with said fixed knife, the improvement which comprises: said drive means including a piston rod and means linking said movable knife to said piston rod, said linking means allowing limited movement of said movable knife relative to said piston rod in directions toward and away from the movement of said piston rod and sensing means to detect if said movable knife has achieved movement toward said piston rod.
Claim 4
Dependent Claim 89 words
A cut-clinch mechanism including a fixed knife and a movable knife and means to drive said movable knife into cutting relationship with said fixed knife, the improvement which comprises: said drive means including a piston rod and means linking said movable knife to said piston rod, said linking means allowing limited movement of said movable knife relative to said piston rod in directions toward and away from the movement of said piston rod and sensing means to detect if said movable knife has achieved movement toward said piston rod.
Claim 5
Dependent Claim 32 words
The cut-clinch mechanism according to claims 1 or 2 wherein said drive means has a holding means disposed at one end thereof and said sensing means is disposed in said holding means.
Claim 6
Dependent Claim 32 words
The cut-clinch mechanism according to claim 3 wherein said sensing means is an electrical contact disposed so as to touch said movable knife if said movable knife has achieved said limited movement.
Claim 7
Dependent Claim 40 words
The cut-clinch mechanism according to claim 4 wherein a spring urges said movable knife away from said sensor, said spring being tensioned so as to be overcome when said movable knife contacts a lead-in wire disposed adjacent said fixed knife.
Claim 8
Dependent Claim 30 words
The cut-clinch mechanism according to claim 4 wherein said sensor includes an electrical contact imbedded within a plastic material so as to insulate said electrical contact from said drive means.
Claim 9
Dependent Claim 118 words
A cut-clinch mechanism including a fixed knife and a movable knife said movable knife being arranged to be driven into a cutting relationship with said fixed knife, the improvement which comprises: a piston rod and a link rigidly affixed to said piston rod; said movable knife having a hole formed therein so as to receive said link, said hole being wider than said link thereby allowing limited movement of said movable knife relative to said link; spring means engaging said movable knife and urging said movable knife away from said piston rod; sensing means disposed within said piston rod and arranged to provide a signal by contact with said movable knife if said limited movement has been achieved.
Claim 10
Dependent Claim 118 words
A cut-clinch mechanism including a fixed knife and a movable knife said movable knife being arranged to be driven into a cutting relationship with said fixed knife, the improvement which comprises: a piston rod and a link rigidly affixed to said piston rod; said movable knife having a hole formed therein so as to receive said link, said hole being wider than said link thereby allowing limited movement of said movable knife relative to said link; spring means engaging said movable knife and urging said movable knife away from said piston rod; sensing means disposed within said piston rod and arranged to provide a signal by contact with said movable knife if said limited movement has been achieved.
Claim 11
Dependent Claim 30 words
The cut-clinch mechanism according to claim 7 wherein said sensing means is an electrical contact imbedded within plastic material so as to insulate said electrical contact from said piston rod.
