  • Patent number: 5022633
    Abstract: A tool which can be held and manipulated in one hand, for grasping and pulling steel fish tapes of the type used to pull electrical wires through building walls comprises two identical handle members having flat and parallel front and rear surfaces. Each handle member has a convex inner transverse wall surface, and a notch cut forward from the rear wall surface behind the convex transverse wall surface to a flat longitudinal plane located approximately midway between the front and rear wall surfaces, the notch terminating in an inner transverse wall plane which serves as an anvil plane. Two handle members are pivotably joined by a pivot pin with their bottom longitudinal notch walls in sliding contact, such that a space for receiving a fish tape is provided between each convex inner transverse wall surface of a handle member and the adjacent anvil plane of the other handle member.

  • Patent number: 4746099
    Abstract: A tool for gripping and pulling steel fish tapes of the type used to pull electrical wiring through conduits and passageways in building construction comprises identical jaw pieces and elongated, rearward extending handlebars. The outer half of each jaw piece has a forward extending jaw member having a convex front surface facing a flat anvil plane formed in a cutout rear half section of the opposite jaw piece. The two jaw pieces are joined by a transversely disposed pivot pin such that a forward extending jaw member is pivotable within the cutout section of the opposite jaw piece, forming a pivotable interdigitated structure. The axis of the pivot pin is located eccentrically with respect to the convex front surface of the forward extending jaw member, thereby providing as the handlebars are pivoted into colinear alignment, a decreasing space between the jaw member and the anvil plane for gripping a fish tape inserted therebetween.
