Abstract
Abstract A hand tool is disclosed for straightening wire and includes three elongated rod-like wire straightening members each having a plurality of wire engaging circular ridges spaced longitudinally of the respective straightener member. Link means interconnects the wire straightener members at the ends thereof for pivotal movement relative to the longitudinal axes thereof, between an open position and a closed position. The wire straightener members in the closed position define a longitudinal passageway between the circular wire engaging ridges for receiving a wire and straightening the wire in response to relative longitudinal movement of the wire in the passageway as pressure is applied exteriorly of the wire straightener members. The circular ridges on each wire straightener member are spaced and located to be disposed in gaps between the circular ridges of each other wire straightener member.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
122 words
A hand tool for straightening wire, comprising: at least three elongated wire straightener members each having a plurality of wire engaging surfaces spaced longitudinally of the respective straightener member; and means interconnecting said wire straightener members for pivotal movement about axis means extending generally parallel to the longitudinal axes of the wire straightener members between an open position and a closed position with the wire straightener members in said closed position defining a longitudinal passageway between said wire engaging surfaces extending generally parallel to the longitudinal axes of the wire straightener members for receiving a wire and straightening the wire in response to relative longitudinal movement of the wire in said passageway as pressure is applied exteriorly of the wire straightener members.
Claim 2
Dependent Claim
122 words
A hand tool for straightening wire, comprising: at least three elongated wire straightener members each having a plurality of wire engaging surfaces spaced longitudinally of the respective straightener member; and means interconnecting said wire straightener members for pivotal movement about axis means extending generally parallel to the longitudinal axes of the wire straightener members between an open position and a closed position with the wire straightener members in said closed position defining a longitudinal passageway between said wire engaging surfaces extending generally parallel to the longitudinal axes of the wire straightener members for receiving a wire and straightening the wire in response to relative longitudinal movement of the wire in said passageway as pressure is applied exteriorly of the wire straightener members.
Claim 3
Dependent Claim
24 words
The hand tool of claim 1 wherein said wire engaging surfaces are generally annular about the axis of their respective elongated wire straightener member.
Claim 4
Dependent Claim
23 words

Claim 5
Dependent Claim
59 words
The hand tool of claim 1 wherein said spaced wire engaging surfaces are located along each wire straightener member with respect to the wire engaging surfaces of the other straightener members such that each wire engaging surface is disposed in a gap between a pair of wire engaging surfaces on each other wire straightener member in said closed position.
Claim 6
Dependent Claim
38 words
The hand tool of claim 4 wherein the circular ridges on each wire straightener member are spaced and located to be disposed in gaps between the circular ridges of each other wire straightener member in said closed position.
Claim 7
Dependent Claim
26 words
The hand tool of claim 1 wherein said interconnecting means comprises link members between one of said wire straightener members and the other wire straightener members.
Claim 8
Dependent Claim
26 words

Claim 9
Dependent Claim
14 words
The hand tool claim claim 7 wherein the link members are of equal length.
Claim 10
Dependent Claim
127 words
A hand tool for straightening wire, comprising: three elongated rod-like wire straightener members each having a plurality of wire engaging circular ridges spaced longitudinally along the respective wire straightener member, link means interconnecting said wire straightener members for pivotal movement relative to the longitudinal axes thereof between an open position and a closed position, said wire straightener members in said closed position defining a longitudinal passageway between said circular ridges for receiving a wire and straightening the wire in response to relative longitudinal movement of the wire in said passageway as pressure is applied exteriorly of the wire straightener members, said circular ridges on each wire straightener member being spaced and located to be disposed in gaps between the circular ridges of each other wire straightener member.
Claim 11
Dependent Claim
127 words
A hand tool for straightening wire, comprising: three elongated rod-like wire straightener members each having a plurality of wire engaging circular ridges spaced longitudinally along the respective wire straightener member, link means interconnecting said wire straightener members for pivotal movement relative to the longitudinal axes thereof between an open position and a closed position, said wire straightener members in said closed position defining a longitudinal passageway between said circular ridges for receiving a wire and straightening the wire in response to relative longitudinal movement of the wire in said passageway as pressure is applied exteriorly of the wire straightener members, said circular ridges on each wire straightener member being spaced and located to be disposed in gaps between the circular ridges of each other wire straightener member.
Claim 12
Dependent Claim
30 words
