Claims
- 1. A nail strip for holding a plurality of nails together in spaced apart parallel relation for use in a fastening element driving tool using a piston for driving the nails from an axially extending bore in a muzzle part of the tool, each said nail comprises an axially extending shank and a head at one end of said shank projecting laterally outwardly from said shank and having a circumferentially extending lateral surface, and said nail strip comprises severable connecting means securing the nails together so that an individual nail can be separated from said nail strip when the individual nail is driven by the piston from the muzzle bore, individual said nails in the nail strip are arranged to be inserted into the bore into position to be driven by the piston, wherein the improvement comprises that said nail strip includes a plurality of guide bushings each positioned on the shank of a different one of said individual nails, each said guide bushing extending in the axial direction of the nail shank and having two circumferentially and axially extending circularly continuous annular guide surfaces projecting laterally outwardly from the nail shank at least to the lateral surface of the head of said nail secured by said guide bushing, said two guide surfaces on each said guide bushing being spaced apart in the axial direction of the nail shank and located at the axially spaced opposite ends of said guide bushing, said guide surfaces being shaped to conform in sliding relation with the muzzle bore, each said guide bushing between the axially spaced guide surfaces being inset relative to said guide surfaces transversely of the axial direction of said bushing so that the axial length between said guide surfaces has a reduced transverse cross section relative to the corresponding cross sections of said guide surfaces, adjacent said guide bushings being spaced apart transversely of the axial direction of said shanks and being interconnected by said connecting means, and said connecting means projecting radially outwardly beyond said circularly continuous annular guide surfaces and spacing apart said annular guide surfaces on said adjacent guide bushings whereby the heads of the nails are in spaced apart relation, said connecting means comprises a web integral with said guide bushings and extending in the axial direction of the nail shank for at least half of the corresponding axial length of said guide bushings, said annular guide surfaces have a dimension in the axial direction of the nail shank corresponding to 0.1 to 0.3 times the diameter of said annular guide surfaces, and each said web has a reduced strength section spaced between adjacent said guide bushings and said reduced strength section being formed by a V-shaped recess formed into at least one end of said web extending transversely of the axial direction of the nail shank.
- 2. A nail strip, as set forth in claim 1, wherein said bushings have a section extending between said annular guide surfaces with at least a portion of said section spaced radially inwardly from the circumferential surface of said annular guide surfaces and said section forming a rectangular bore for holding the nail shank.
- 3. A nail strip, as set forth in claim 2, wherein said section of said guide bushing extending between said annular guide surfaces has exterior planar surfaces extending in parallel relation and arranged to guide the nail strip into the muzzle bore.
