Abstract
A staple removing device has a pair of levers pivotally coupled at one end on an axis such that their other ends are capable of movement toward one another. A bias spring acts on the pair of levers for biasing the pair of levers into an open position. A pair of extraction jaws on the other end of the pair of levers have engaging ends extending toward the other of the pair of levers for engaging the underside of a staple embedded in a material to lift the staple away from the material. A capture slot is formed one of the pair of levers that captures a staple when removed.

A staple removing device comprising:
- a pair of levers pivotally coupled at one end on an axis such that their other ends are capable of movement toward one another;
- a bias spring acting on said pair of levers for biasing said pair of levers into an open position;
- a pair of extraction jaws on said other end of said pair of levers having engaging ends extending toward the other of said pair of levers for engaging the underside of a staple embedded in a material to lift said staple away from said material;
- a capture slot in one of said pair of levers that captures a staple when removed;
- and
- an engaging member attached to one of said levers and located adjacent said extraction jaw extending substantially parallel to said extractions jaw but spaced therefrom for engaging the top side of a staple at about the center thereof simultaneously with engagement of said engaging ends of said extraction jaws with the underside of said staple;
- said engaging member extends at least to a plane which includes said engaging ends of said extraction means and said pivotal axis of said levers;
- and
- wherein said engaging member will anchor said staple to said material at a middle portion thereof and the extraction jaws will uniformly withdraw the staple ends for removal.
