Abstract

A staple remover for removing staples from stapled materials utilizing an inclined plane in combination with a gripper. First and second jaws are provided, each have two jaw members. The two jaw members of the first jaw are spaced from each other just less than the width of a staple. The two jaw members of the second jaw are spaced from each other less than the spacing of the jaw members for the first jaw so that the second jaw may insert within the first jaw. The first and second jaws are connected together by a pivot and are resiliently biased in an open position. Each of the jaw members of the first and second jaws terminate in a pointed extremity. Each of the jaw members of the first and second jaws further have an upper and lower cam surface which smoothly diverge from each other rearwardly from the pointed extremity. The combination of the upper and lower cams of each jaw member form two parallel wedge shapes which are used as dual inclined planes to cause a staple to be separated from materials to which it is stapled. The jaw members of one of the jaws are each provided with a notch spaced from the aforesaid pointed extremity thereof. A staple is removed by squeezing the jaws together thereby forcing the pointed extremities to move under the staple, the inclined plane action of the upper and lower cams causing the staple to be partially released from the material to which it is stapled. Thereupon, the staple will encounter the aforesaid notches, causing the staple to be gripped by action of the cam surface of the non-notched jaw members of the other jaw, and allowing for final staple removal by pulling.
