Abstract
Abstract A wire stripper having an elongated lever which is pivotally connected thereto for movement into and out of engagement with a plurality of detents to limit the extent to which the handles and the jaws of the wire stripper are spread. A stop element on one of the handles of the wire stripper limits the extent to which the jaws can be closed to strip the insulation from a wire of predetermined thickness without cutting the conductor therein.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
97 words
In a wire striPper of the type comprising first and second arms pivotally connected to each other to define two facing jaws with wire stripping means thereon and two handles with means for biasing the handles and jaws to an open position, the improvement comprising first means for limiting the minimum opening between said jaws to a predetermined range of openings, second means for selectively limiting the maximum opening between said handles over a predetermined range of openings said second means cooperating with said first means throughout the range of openings to prevent said arms from spreading.
Claim 2
Dependent Claim
97 words
In a wire striPper of the type comprising first and second arms pivotally connected to each other to define two facing jaws with wire stripping means thereon and two handles with means for biasing the handles and jaws to an open position, the improvement comprising first means for limiting the minimum opening between said jaws to a predetermined range of openings, second means for selectively limiting the maximum opening between said handles over a predetermined range of openings said second means cooperating with said first means throughout the range of openings to prevent said arms from spreading.
Claim 3
Dependent Claim
57 words
A wire stripper as defined in claim 1 wherein said second limiting means includes a plurality of detents disposed along one of said arms, and means for selectively engaging each of said detents, said last named means being disposed on said other arm, and each of said detents correspond to a different maximum opening between said handles.
Claim 4
Dependent Claim
97 words
A wire stripper as defined in claim 2 wherein said first means comprises a stop member coupled to one of said arms and engageable with said other arm for limiting the opening between said jaws to a predetermined minimum, means for enabling said stop member to move along said one arm, means for selectively fixing said stop member to said one arm at a plurality of locations thereon to vary said minimum opening and said detents and said selective engaging means cooperate with said stop member at each of said locations to prevent said arms from spreading.
Claim 5
Dependent Claim
62 words
A wire stripper as defined in claim 2, wherein said means for engaging said detents is an elongated member, means pivoting said member to said other arm intermediate the ends of said member so that it lies along said arm with one end adjacent the handle portion of said other arm and its other end adjacent the detents on said one arm.
Claim 6
Dependent Claim
22 words
A wire stripper as defined in claim 4 wherein said detents comprise notches disposed along the rear face of said one arm.
Claim 7
Dependent Claim
70 words
A wire stripper as defined in claim 4 wherein said detents are linearly arranged along the rear face of said jaw of said one arm and said engaging member includes a stop to limit its pivotal movement in one direction, and said stop corresponds to the detents furthest from the handle of said one arm so that the maximum opening of said handles in said predetermined range is limited thereby.
Claim 8
Dependent Claim
47 words
A wire stripper as defined in claim 6 wherein said detent closest to the handle of said one arm is engaged by said engaging member when it is pivoted from said stop so that the minimum opening of said handles in said predetermined range is defined thereby.
Claim 9
Dependent Claim
65 words
A wire stripper as defined in claim 4 wherein said elongated member comprises a first portion which is pivoted to said other arm and a second portion which is coupled to said first portion, one part of said second portion being engageable by an operator to move said elongated member about said pivot, and another part of said second portion being engageable with said detents.
Claim 10
Dependent Claim
115 words
A wire stripper as defined in claim 1 wherein said first means comprises an elongated slot in one of said arms with a stop member mounted in said slot for movement therealong and means for fixing said stop member at locations along said slot to limit the opening between said jaws to a predetermined minimum so that the conductor in the wire that is stripped will not be cut, the improvement comprising said stop member being comprised of a first element extending through said slot for engagement with said other arm and a second element coupled to said first element, and means for releasably coupling said second element to said one arm along said slot.
Claim 11
Dependent Claim
26 words
A wire stripper as defined in claim 9 wherein said second element is generally bowed so that its intermediate portion is spaced from said one arm.
Claim 12
Dependent Claim
25 words
A wire stripper as defined in claim 9 including graduations disposed along said slot so that said first element can be positioned at predetermined locations.
