Abstract
Abstract A pliers having a pair of jaw members each of which includes a pair of positioning legs for placing, removing and crimping light wire pins and other light wire devices. The jaws include a pair of transverse mating grooves, one in each jaw member adjacent the positioning legs and a longitudinal slot completely through the upper jaw member and partially through the lower jaw member, and a trough adjacent the partial slot in the lower jaw member for loosely receiving the spring coils of various light wire devices while the legs of the devices pass through the mating grooves of the jaw members.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
125 words
A universal orthodontic pliers comprising: a pair of lever arms pivoted together having handle means at one end and jaw means at the opposite end; the jaw means including an upper and a lower jaw member; a pair of transverse mating grooves, one in each jaw member; a pair of positioning legs on the end of each jaw member oppositely positioned from each other; a longitudinal slot passing through the upper jaw member between said pair of positioning legs; a partial longitudinal slot in the lower jaw member oppositely positioned from the slot in the upper jaw member with the pair of positioning legs defining the sides of the partial slot, both slots being of a width less than the width of the transverse grooves.
Claim 2
Dependent Claim
125 words
A universal orthodontic pliers comprising: a pair of lever arms pivoted together having handle means at one end and jaw means at the opposite end; the jaw means including an upper and a lower jaw member; a pair of transverse mating grooves, one in each jaw member; a pair of positioning legs on the end of each jaw member oppositely positioned from each other; a longitudinal slot passing through the upper jaw member between said pair of positioning legs; a partial longitudinal slot in the lower jaw member oppositely positioned from the slot in the upper jaw member with the pair of positioning legs defining the sides of the partial slot, both slots being of a width less than the width of the transverse grooves.
Claim 3
Dependent Claim
48 words
A universal orthodontic pliers as set forth in claim 1, including a trough means in the lower jaw member for loosely receiving spring coils, the trough means extending longitudinally inward on the jaw member from the partial slot and has a width substantially greater than the partial slot.
Claim 4
Dependent Claim
53 words
A universal orthodontic pliers as set forth in claim 1, wherein said transverse groove in each jaw member has a depth greater than half the width of the groove so that when the grooves are in mating contact, the opening defined has a width less than the combined depth of both transverse grooves.
Claim 5
Dependent Claim
52 words
A universal orthodontic pliers as set forth in claim 1, wherein the longitudinal slot in the upper jaw member and partial slot in the lower jaw member are defined by the space between each pair of positioning legs and each slot is of a width substantially the same as each positioning leg.
Claim 6
Dependent Claim
31 words
A universal orthodontic pliers as set forth in claim 1, wherein the depth of the transverse groove in the lower jaw member is greater than that in the upper jaw member.
Claim 7
Dependent Claim
46 words
A universal orthodontic pliers as set forth in claim 1, wherein each jaw member has a plane of contact with its opposing jaw member; lying in said planes are the ends of the positioning legs of each jaw member and the edges of said transverse grooves.
Claim 8
Dependent Claim
145 words
A universal orthodontic pliers comprising: a pair of lever arms pivoted together with handle means at one end and jaw means at the other; the jaw means includes an upper and a lower jaw member each having a contacting surface; a pair of transverse mating grooves, one in the contacting surface of each jaw member; a pair of parallel positioning legs on the ends of each jaw member, oppositely aligned with the opposing jaw member, with the ends of said legs in the contacting surface; a longitudinal slot passing through the upper jaw member between said pair of positioning legs; and a partial longitudinal slot in the lower jaw member oppositely positioned and aligned with the slot in the upper jaw member with the pair of positioning legs defining the sides of the partial slot, both slots being of width less than the transverse grooves.
Claim 9
Dependent Claim
145 words
A universal orthodontic pliers comprising: a pair of lever arms pivoted together with handle means at one end and jaw means at the other; the jaw means includes an upper and a lower jaw member each having a contacting surface; a pair of transverse mating grooves, one in the contacting surface of each jaw member; a pair of parallel positioning legs on the ends of each jaw member, oppositely aligned with the opposing jaw member, with the ends of said legs in the contacting surface; a longitudinal slot passing through the upper jaw member between said pair of positioning legs; and a partial longitudinal slot in the lower jaw member oppositely positioned and aligned with the slot in the upper jaw member with the pair of positioning legs defining the sides of the partial slot, both slots being of width less than the transverse grooves.
Claim 10
Dependent Claim
52 words
A universal orthodontic pliers as set forth in claim 7, including a trough means in the contacting surface of the lower jaw member for loosely receiving spring coils, the trough means extends longitudinally inward on the jaw member from the partial slot and has a width substantially greater than the partial slot.
Claim 11
Dependent Claim
53 words
A universal orthodontic pliers as set forth in claim 7, wherein said transverse groove in each jaw member has a depth greater than half the width of the groove so that when the grooves are in mating contact, the opening defined has a width less than the combined depth of both transverse grooves.
Claim 12
Dependent Claim
70 words
A universal orthodontic pliers as set forth in claim 7, wherein said transverse groove in each jaw member has a depth greater than half the width of the groove so that when the grooves are in mating contact, the opening defined has a width less than the combined depth of both transverse grooves and the groove in the lower jaw member is greater than that in the upper jaw member.
Claim 13
Dependent Claim
52 words
A universal orthodontic pliers as set forth in claim 7, wherein the longitudinal slot in the upper jaw member and partial slot in the lower jaw member are defined by the space between each pair of positioning legs and each slot is of a width substantially the same as each positioning leg.
Claim 14
Dependent Claim
20 words
A universal orthodontic pliers as set forth in claim 7, wherein the positioning legs are tapered toward their free ends.
