Abstract
Abstract The present invention relates generally to ground wire clips for attachment to wooden poles and the like, and more particularly to a novel and very practical electrically nonconductive one piece ground wire clip. Embodiments of the present invention disclosed herein include an electrically nonconductive one piece clip having an elongate shank section and a hook shaped head section integral with one extremity of said shank section. The entering extremity of the elongate shank section is relatively sharp to facilitate driving the shank into a wooden workpiece. The hook shaped head provides a conductor accomodating recess and means is provided in the vicinity of the head for limiting the extent to which said shank may be longitudinally driven into a workpiece. Barbs or teeth disposed on opposite sides of the shank section are so arranged as to reduce to a minimum the possible fracture or severance of wooden fibers and function effectively to resist unauthorized or unintentional retrograde movement or withdrawal of the shank.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
281 words
A clip capable of being hammer-driven into a wooden pole to hold a ground wire against said pole, said clip comprising an integral elongated shank portion and a head portion of an electrically nonconductive plastic material, said shank portion being substantially rectangular in transverse cross-section and the side walls thereof tapering from said head portion to a chisel point at the other end thereof, a plurality of barbs on two opposite side walls of said shank portion, said barbs on each of said two opposite side walls arranged in a spaced apart relationship longitudinally of said shank portion and each of said barbs extending substantially completely transversely across said side walls, a plurality of recesses in the other two opposite side walls of said shank portion, said recesses arranged in a spaced apart relationship longitudinally of said shank portion and spanning said barbs to render at least the ends of said barbs deflectable inwardly of said shank portion, said head portion including a central driving section in axial alignment with said shank portion and a hook section and a stop section, said hook and stop sections arranged on opposite sides of said driving section and extending transversely outwardly of said clip, said stop section including a shoulder extending outwardly of said clip and terminating in a transverse plane substantially including the longitudinally inner end of said head portion and an integral web perpendicularly arranged between said shoulder and one side of said driving section, said hook section comprising a hook portion directed outwardly from the head end of said driving section and longitudinally of said driving section and frangible web means integrally interconnected between said driving section and said hook portion.
Claim 2
Dependent Claim
281 words
A clip capable of being hammer-driven into a wooden pole to hold a ground wire against said pole, said clip comprising an integral elongated shank portion and a head portion of an electrically nonconductive plastic material, said shank portion being substantially rectangular in transverse cross-section and the side walls thereof tapering from said head portion to a chisel point at the other end thereof, a plurality of barbs on two opposite side walls of said shank portion, said barbs on each of said two opposite side walls arranged in a spaced apart relationship longitudinally of said shank portion and each of said barbs extending substantially completely transversely across said side walls, a plurality of recesses in the other two opposite side walls of said shank portion, said recesses arranged in a spaced apart relationship longitudinally of said shank portion and spanning said barbs to render at least the ends of said barbs deflectable inwardly of said shank portion, said head portion including a central driving section in axial alignment with said shank portion and a hook section and a stop section, said hook and stop sections arranged on opposite sides of said driving section and extending transversely outwardly of said clip, said stop section including a shoulder extending outwardly of said clip and terminating in a transverse plane substantially including the longitudinally inner end of said head portion and an integral web perpendicularly arranged between said shoulder and one side of said driving section, said hook section comprising a hook portion directed outwardly from the head end of said driving section and longitudinally of said driving section and frangible web means integrally interconnected between said driving section and said hook portion.
Claim 3
Dependent Claim
