Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
206 words
In a dental pliers of the type comprising two arms which are connected to each other by a pivot member to define two handles and two jaws, the improvement comprising, an anvil on one of said jaws and a cutting edge on said other jaw, said anvil and said cutting edge being cooperable to cut a wire, said cutting edge being defined by a face and caming surface, said camming surface being angularly disposed with respect to said anvil when said jaws are closed so that said camming surface and said anvil define a generally V-shaped opening, a resilient elongated member, said member including a means for coupling it to said pliers and a leg, said leg lying along said camming surface and extending into the opening between said cutting edge and said anvil when said jaws are open so that when said jaws are closed on a wire said camming surface urges said leg toward said anvil to engage the wire between said leg and said anvil before being cut to enable said pliers to be moved along the wire while it is so engaged, and said leg is operative to retain the distal end of the wire on said anvil after it is cut.
Claim 2
Dependent Claim
206 words
In a dental pliers of the type comprising two arms which are connected to each other by a pivot member to define two handles and two jaws, the improvement comprising, an anvil on one of said jaws and a cutting edge on said other jaw, said anvil and said cutting edge being cooperable to cut a wire, said cutting edge being defined by a face and caming surface, said camming surface being angularly disposed with respect to said anvil when said jaws are closed so that said camming surface and said anvil define a generally V-shaped opening, a resilient elongated member, said member including a means for coupling it to said pliers and a leg, said leg lying along said camming surface and extending into the opening between said cutting edge and said anvil when said jaws are open so that when said jaws are closed on a wire said camming surface urges said leg toward said anvil to engage the wire between said leg and said anvil before being cut to enable said pliers to be moved along the wire while it is so engaged, and said leg is operative to retain the distal end of the wire on said anvil after it is cut.
Claim 3
Dependent Claim
53 words
A dental pliers as defined in claim 1 wherein a bight is disposed in said elongated resilient member intermediate said coupling means and said leg, said bight bearing against the jaw on which said cutting edge is located to support said leg as said leg retains the distal ends of the cut wire.
Claim 4
Dependent Claim
61 words
A dental pliers as defined in claim 1, wherein said anvil includes an edge, said cutting edge including a face, and said anvil edge abutts said face when dental wire is cut so that said face can be placed close to a dental appliance to which the wire is connected to substantially eliminate an exposed wire end in a patient''s mouth.
Claim 5
Dependent Claim
43 words
A dental pliers as defined in claim 2, an opening in said pliers, said opening being substantially coaxial with said pivot pin, and the end of said elongated resilient member remote from said leg is received in and is retained in said opening.
Claim 6
Dependent Claim
33 words
A dental pliers as defined in claim 3 wherein said cutting edge and said edge of said anvil are disposed at an angle of about 60* from a plane defined by said arms.
Claim 7
Dependent Claim
24 words
A dental pliers as defined in claim 3 wherein said anvil edge and said face are disposed between said pivotal connection and said leg.
Claim 8
Dependent Claim
129 words
A resilient elongated member for use in a dental pliers of the type used to cut wire, said member comprising an elongated body portion, a downwardly extending bight formed at one end of said body portion, a first leg coupled to said bight at an end thereof which is spaced from said body portion, said first leg being in substantial alignment with said elongated body portion so that said first leg and said body portion can lie along a surface of the pliers, a downwardly and longitudinally extending second leg coupled to the end of said first leg, said second leg having a distal end of sufficient length to extend into the opening between the cutting members of the pliers, and means for coupling said member to the pliers.
Claim 9
Dependent Claim
129 words
A resilient elongated member for use in a dental pliers of the type used to cut wire, said member comprising an elongated body portion, a downwardly extending bight formed at one end of said body portion, a first leg coupled to said bight at an end thereof which is spaced from said body portion, said first leg being in substantial alignment with said elongated body portion so that said first leg and said body portion can lie along a surface of the pliers, a downwardly and longitudinally extending second leg coupled to the end of said first leg, said second leg having a distal end of sufficient length to extend into the opening between the cutting members of the pliers, and means for coupling said member to the pliers.
Claim 10
Dependent Claim
38 words
A member as defined in claim 7 wherein said means for coupling said member to the pliers comprises a generally downwardly extending tail, said tail being coupled to said body portion at its end remote from said bight.
Claim 11
Dependent Claim
28 words
A member as defined in claim 8 wherein said bight is generally planar and is disposed at a lateral angle of about 50 with respect to said tail.
Claim 12
Dependent Claim
23 words
A member as defined in claim 7 wherein said first leg extends in a generally downward lateral direction with respect to said body.
Claim 13
Dependent Claim
35 words
A member as defined in claim 10 wherein downward direction is an angle of about 25* and said lateral direction is about 10* from said body portion and in the same direction as said bight.
Claim 14
Dependent Claim
25 words
A member as defined in claim 10 wherein said second leg extends in a direction which is downward, forward and laterally diverging from said bight.
Claim 15
Dependent Claim
39 words
A member as defined in claim 12 wherein said downward direction is at an angle of about 80* and said lateral direction is at an angle of about 10* from the plane defined by body portion and said tail.
