Abstract
Abstract A staple removing device including a pair of hinged, opposing jaws. Each jaw includes an anvil member that is movable into and out of contact engagement with the other anvil member upon relative movement of the jaws. In one embodiment, the anvil members are used to release a staple that has been partially removed by the jaws. In another embodiment, the anvil members engage the staple simultaneously with use of the jaws to open the staple so as to facilitate complete release of the staple.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
201 words
A staple removing device, including an upper jaw member having a first and second side sections and a lower jaw member having third and fourth side sections, the upper jaw member being pivotally connected to the lower jaw member, the device comprising: a first plate member integral with the upper jaw member, the first plate member positioned between the first and second side sections; a second plate member integral with the lower jaw member, the second plate member positioned between the third and fourth side sections movable to a contact position with the first plate member when the upper and lower jaw members are moved toward each other so that a staple is engageable between the first and second plate members; and wherein the first jaw member includes a first gap and a second gap, the first gap being located between the first plate member and the first side section, the second gap being located between the first plate member and the second side section such that the third side section is received within the first gap and the fourth side section is received within the second gap when the first and second plate members are in contact with each other.
Claim 2
Dependent Claim
201 words
A staple removing device, including an upper jaw member having a first and second side sections and a lower jaw member having third and fourth side sections, the upper jaw member being pivotally connected to the lower jaw member, the device comprising: a first plate member integral with the upper jaw member, the first plate member positioned between the first and second side sections; a second plate member integral with the lower jaw member, the second plate member positioned between the third and fourth side sections movable to a contact position with the first plate member when the upper and lower jaw members are moved toward each other so that a staple is engageable between the first and second plate members; and wherein the first jaw member includes a first gap and a second gap, the first gap being located between the first plate member and the first side section, the second gap being located between the first plate member and the second side section such that the third side section is received within the first gap and the fourth side section is received within the second gap when the first and second plate members are in contact with each other.
Claim 3
Dependent Claim
25 words

Claim 5
Dependent Claim
193 words
A staple removing device, including an upper jaw member having first and second side sections and a lower jaw member having third and fourth side sections, the upper jaw member being pivotally connected to the lower jaw member, the device comprising: a first plate member integral with the upper jaw member, the first plate member attached to the first and second side sections; a second plate member integral with the lower jaw member, the second plate member attached to the third and fourth side sections movable to a contact position with the first plate member when the upper and lower jaw members are moved toward each other so that a staple is engageable between the first and second plate members; and wherein the first plate member has a first edge portion, the first plate member being substantially perpendicular to the first and second side sections, and the second plate member has a second edge portion, the second plate member being substantially perpendicular to the third and fourth side sections, whereby the first edge contacts the second edge when the upper and lower jaw members are moved together so that a staple is engaged.
Claim 6
Dependent Claim
193 words
A staple removing device, including an upper jaw member having first and second side sections and a lower jaw member having third and fourth side sections, the upper jaw member being pivotally connected to the lower jaw member, the device comprising: a first plate member integral with the upper jaw member, the first plate member attached to the first and second side sections; a second plate member integral with the lower jaw member, the second plate member attached to the third and fourth side sections movable to a contact position with the first plate member when the upper and lower jaw members are moved toward each other so that a staple is engageable between the first and second plate members; and wherein the first plate member has a first edge portion, the first plate member being substantially perpendicular to the first and second side sections, and the second plate member has a second edge portion, the second plate member being substantially perpendicular to the third and fourth side sections, whereby the first edge contacts the second edge when the upper and lower jaw members are moved together so that a staple is engaged.
