Abstract
Abstract A device for removing broken portions of wire staples of the type used to secure together sheets of paper or the like, said device comprising a pair of overlying planar arms pivoted together on an axis normal thereto, said arms having cooperating notches formed in matching edges thereof generally radially of said pivot, whereby relative pivotal movement of said arms moves said notches from a position of registry, at which they may be engaged over the projecting portion of a broken staple, to an out-of-registry position to grip said wire between the edges thereof, whereupon said arms may be used as a pulling tool to withdraw the broken staple portion from the sheets in which it is engaged.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
230 words
A broken staple remover comprising: a. a pair of planar, elongated arms disposed in intersecting, overlapping relation, b. means pivotally interconnecting said arms intermediate their ends for relative pivotal movement about an axis normal to their planes, one corresponding pair of ends of said arms constituting a pair of angularly confronting jaws operable to be moved toward each other into partially overlapping relation by relative pivotal movement of said arms, and c. stop means carried by said arms to limit the closing movement of said jaws to a position at which at least a portion of the radial lengths of said jaws are spaced angularly apart by a distance less than the diameter of the wire of which a broken staple to be removed is formed, the confronting faces of said jaws being arcuately concave, all points of each of said jaws lying at one side of a radius line drawn from the pivotal axis of said arms to the outer end of said jaw, the inner end of each of said jaws being the point thereof having the greatest spacing from said radius line, whereby a wire engaged between said jaws is cammed by said jaws toward the inner ends thereof, said stop means preserving a minimum spacing between the inner ends of said jaws less than the diameter of the wire of which a broken staple is formed.
Claim 2
Dependent Claim
230 words
A broken staple remover comprising: a. a pair of planar, elongated arms disposed in intersecting, overlapping relation, b. means pivotally interconnecting said arms intermediate their ends for relative pivotal movement about an axis normal to their planes, one corresponding pair of ends of said arms constituting a pair of angularly confronting jaws operable to be moved toward each other into partially overlapping relation by relative pivotal movement of said arms, and c. stop means carried by said arms to limit the closing movement of said jaws to a position at which at least a portion of the radial lengths of said jaws are spaced angularly apart by a distance less than the diameter of the wire of which a broken staple to be removed is formed, the confronting faces of said jaws being arcuately concave, all points of each of said jaws lying at one side of a radius line drawn from the pivotal axis of said arms to the outer end of said jaw, the inner end of each of said jaws being the point thereof having the greatest spacing from said radius line, whereby a wire engaged between said jaws is cammed by said jaws toward the inner ends thereof, said stop means preserving a minimum spacing between the inner ends of said jaws less than the diameter of the wire of which a broken staple is formed.
Claim 3
Dependent Claim
78 words
A device as recited in claim 1 wherein the spacing of the inner end of each jaw from a radius line drawn from the pivotal axis of said arms to the outer end of said jaw is at least as great as the diameter of the wire of which a broken staple is formed, whereby said jaws move into overlapping relation outwardly from said wire after said wire has been cammed to the inner ends of said jaws.
Claim 4
Dependent Claim
39 words
A device as recited in claim 1 wherein the outer end portions of said jaws are smooth and blunt, whereby to facilitate the camming action thereof in moving a wire engaged therebetween toward the inner ends of said jaws.
Claim 5
Dependent Claim
56 words
A device as recited in claim 2 wherein the outer end portions of said jaws are smooth and blunt, whereby to defeat the cutting of a wire therebetween as these portions of said jaws move into overlapping relation, and to facilitate the camming action thereof in moving said wire toward the inner ends of said jaws.
Claim 6
Dependent Claim
65 words
A device as recited in claim 3 wherein the inner end portion of at least one of said jaws is sharpened to provide a cutting edge lying in the plane thereof engaging the other of said jaws, whereby a staple wire disposed between the inner ends of said jaws is partially severed when said jaws are closed to the limit permitted by said stop means.
Claim 7
Dependent Claim
65 words
A device as recited in claim 4 wherein the inner end portion of at least one of said jaws is sharpened to provide a cutting edge lying in the plane thereof engaging the other of said jaws, whereby a staple wire disposed between the inner ends of said jaws is partially severed when said jaws are closed to the limit permitted by said stop means.
