Abstract
Abstract An orthodontic plier-type tool is disclosed in which jaws are formed to bend a wire into the desired open or closed loop sizes as determined for the particular arch wire to be used in the mouth of the patient. The jaws of this plier include a mating conically shaped male and female wire bending or straightening means. In one embodiment is shown wire cutting means carried by the jaws, thus requiring only one tool to be used to cut and form an arch wire as used by the orthodontist in his task of straightening children''s teeth.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
375 words
A plier-type tool for orthodontists and the like and adapted for bending and forming tempered wire such as for arch wires and the like, said tool including: (a) a pair of plier members each having a handle and a jaw portion, said members retained in a pivotal relationship by a pivot pin, said plier members selectively movable from an open to a closed condition by manipulation of the handle portions of the members; (b) a generally larger jaw portion formed in each jaw and extending from the pivot pin to a mid portion from which the jaw tapers toward the distal end thereof, said larger portion of each jaw having their facing portions generally planar and adapted to meet when the pliers are in a closed condition; (c) at least one transverse wire retaining groove formed in each of the planar surfaces of the jaw portions, said grooves disposed at a generally right angle to the center line of the jaw, said grooves cooperatively shaped and positioned so as to mate with the other groove when the jaws are closed and in this groove to grip a wire and define a straight length retaining means as the wire is formed into a loop; (d) a circular cross-sectional portion formed on one jaw and providing at least two substantially different diameter circular mandrels for forming circular configurations and loops in the wire; (e) a male conically shaped die form comprising an exterior segment portion of said conical form, this die portion disposed in a tapered attitude and extending a small distance above the planar surface of the generally larger jaw portion of one of the jaws, and (f) a female conically shaped die form comprising an exterior segment portion of said conical form, this die portion disposed in a tapered attitude and extending a small distance below the planar surface of the generally larger jaw portion of the other of the jaws, the female die form disposed in a cooperative position with said male form and with the radius of the female form sufficiently greater than the male form to permit a wire of determined diameter to be bent to a curve having a radius of at least a half an inch without deforming the wire.

Claim 3
Dependent Claim
49 words
An orthodontists plier-type tool for bending arch wires as in claim 1 in which the conically-shaped die form segments have their greatest extent disposed toward the pivot pin with the conically-shaped portions diminishing to the planar surface at a point midway of the jaw and toward the distal end.
Claim 4
Dependent Claim
58 words
An orthodontist plier-type tool for bending arch wires as in claim 1 in which the conically-shaped die forms have a diameter of at least 1 inch and with the male portion having a greatest extent above the planar surface of about one-sixteenth inch, a width of about three-eighths of an inch and a length of about one-half inch.
Claim 5
Dependent Claim
59 words
An orthodontist plier-type tool for bending arch wires as in claim 1 in which there are at least two transverse wire retaining grooves formed in the planar surface of the greater portion of the jaws, said jaws being stepped in width and with a groove formed in each width so as to provide transverse gripping grooves of different lengths.
Claim 6
Dependent Claim
34 words
An orthodontist plier-type tool for bending arch wires as in claim 1 in which the jaws are provided with complementary wire cutting means enabling the wire to be cut both before and after forming.
Claim 7
Dependent Claim
38 words
An orthodontist plier-type tool for bending arch wires as in claim 5 in which the wire cutting means are hardened inserts secured to and carried by the jaws so as to provide a shear cut of the wire.
Claim 8
Dependent Claim
40 words
An orthodontist plier-type tool for bending arch wires as in claim 1 in which the circular cross sectional jaw portion is made with at least three adjacent different diameters having a common surface at the surface facing the other jaw.
Claim 9
Dependent Claim
50 words
An orthodontist plier-type tool for bending arch wires as in claim 7 in which the face portion of the jaw opposite the circular cross sectional portion has a shallow partly circular recess which mates with the circular cross-section to grip without deformation a wire being formed into a circular loop.
