Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
89 words
A pivot comprising: first and second adjacent elements each having opposite plane faces, arcuate grooves formed in said faces first and second rings disposed in said grooves, each ring being continuous through a groove in each of the elements to provide pivotal motion of the elements about an axis commonly concentric with the rings, first and second retainer members disposed in overlying relationship with said opposite plane faces to retain said rings in said grooves, and means for securing said members and said elements together in an operative assembly.
Claim 2
Dependent Claim
89 words
A pivot comprising: first and second adjacent elements each having opposite plane faces, arcuate grooves formed in said faces first and second rings disposed in said grooves, each ring being continuous through a groove in each of the elements to provide pivotal motion of the elements about an axis commonly concentric with the rings, first and second retainer members disposed in overlying relationship with said opposite plane faces to retain said rings in said grooves, and means for securing said members and said elements together in an operative assembly.
Claim 3
Dependent Claim
44 words
The pivot defined in claim 1 further including: at least one pair stop surfaces formed on and integral with respective elements so as to be brought into mating relationship with one another at a predetermined angular orientation of the elements relatIve to one another.
Claim 4
Dependent Claim
77 words
A tool comprising first and second adjacent jaws having mating edges and opposite plane face, arcuate grooves formed in each of the faces to form first and second substantially contiguous circular channels when the jaws are adjacent, first and second rings coaxially disposed in the channels and slidable relative to at least one of the elements, and means separate from and overlying each of said rings and faces for maintaining the jaws and rings in integral relationship.
Claim 5
Dependent Claim
77 words
A tool comprising first and second adjacent jaws having mating edges and opposite plane face, arcuate grooves formed in each of the faces to form first and second substantially contiguous circular channels when the jaws are adjacent, first and second rings coaxially disposed in the channels and slidable relative to at least one of the elements, and means separate from and overlying each of said rings and faces for maintaining the jaws and rings in integral relationship.
Claim 6
Dependent Claim
50 words
A tool as defined in claim 3 including a pair of handles separate from said jaws and disposed in laterally adjacent relationship and pivotal relative to one another about a point spaced from the axis of said rings, the handles engaging the jaws for engaging and disengaging the mating edges.
Claim 7
Dependent Claim
42 words
A tool as defined in claim 4 wherein the means for maintaining comprises a pair of plates overlying the faces and portions of said handles, and means for interconnecting the plates with the jaws and the handles to form an operative assembly.
Claim 8
Dependent Claim
85 words
A tool as defined in claim 3 wherein each of the jaws is of an elongated and tapered configuration to define laterally spaced rearward legs; a pair of handles separate from said jaws and disposed in laterally adjacent and non-crossing relationship; means for pivotally interconnecting the handles for pivotal motion about an axis spaced from the axis of the rings, the handles having portions engaging the rearward legs such that working the handles toward one another causes the mating edges of the jaws to converge.
Claim 9
Dependent Claim
13 words
A tool as defined in claim 6 wherein the handles are reversely bowed.
Claim 10
Dependent Claim
49 words
A tool as defined in claim 6 wherein the means for maintaining comprises a pair of plates overlying the faces of the jaws and secured together by means of a fastener extending therebetween along the axis of the rings, the plates being pivotally connected to each of the handles.
Claim 11
Dependent Claim
15 words
A tool as defined in claim 8 including bias means for urging the handles apart.
Claim 12
Dependent Claim
78 words
The tool defined in claim 3 wherein said mating edges of said adjacent jaws are sharpened for cutting purposes, and an additional pair of opposite and mating stop surfaces formed on an integral with respective jaws and adjacent to the cutting edges so as to be brought into mating relationship with one another as said cutting edges are also brought into mating relationship with one another to prevent loading of said cutting edges when said jaws are closed.
Claim 13
Dependent Claim
49 words
The tool defined in claim 10 further including a second pair of stop surfaces formed on an integral with the jaws and disposed so as to be brought into mating relationship with one another as said jaws are opened thereby to limit the degree of opening of said jaws.
