Abstract:
A plier for pulling staples from posts and the like, the staples being of the type including a transverse bight portion joining a pair of spaced leg portions, said plier comprising:a pair of members connected in scissor-fashion for pivotal operating action in a plane normal to a pivot axis of said members,said members each including a jaw and a handle portion,said jaws of said pair of members forming a head portion above said axis and opposite of said pivot axis to said handles portions,said head portion having opposite side faces formed by said jaws and disposed in substantially parallel planes normal to said axis,said jaws in a closed position defining a substantially continuous post engaging top edge,said jaws having opposed inner surfaces defining pincer points adjacent said top edge for movement toward engagement on closure of said handles to thereby grasp said bight of said staple thereunder;said jaws having side edges curving smoothly upwardly and inwardly to said opposed inner surfaces of said jaws thereby forming said top edge in the form of continuous ridge in a plier closed condition,said continuous ridge being in the form of a substantially semi-circular top outline of said head portion,said plier including a fulcrum means formed integrally with said head portion and projecting laterally from one of said opposite side faces,said fulcrum means including a pair of fulcrum members, one each being integrally formed with one of said jaws on a common side face of said head portion,said fulcrum means defining upper edges extending in a plane substantially normal to said post engaging top edge of said jaws, so that on swinging movement of said handle portions in a plane normal to said top edge leverage is provided for pulling a staple grasped by said pincer points, anda single hammer head integrally formed with one of said jaws and projecting from the side face of said head portion opposite to said one of said opposite side faces of said head portion,said hammer head being disposed on an axis parallel to but disposed vertically above the pivot axis of the pair of connected members between said pivot axis and said pincer points.
