Abstract

Abstract The wooden handle of a hammer or other impact tool is strengthened and the tool is reinforced against sudden loss of the head by drilling a bore along a substantial portion of the length of the handle from the head end, inserting a tension wire into the bore, and locking the ends of the wire in the bore by means of a plastic, such as an epoxy resin.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 159 words
A wooden handle for the head of an impact tool such as a hammer or the like having means for strengthening the handle against the effects of over-blows, said means comprising an elongated bore leading from an end of said handle adapted to receive the head of said tool and along a substantial portion of the length of the handle, an elongated metal wire tension member extending in the bore from the vicinity of said end and substantially along the length of said bore for a distance substantially more than twice the corresponding dimension of said head, said bore having a cross-sectional area several times the cross-sectional area of said tension member, and an epoxy resin bonding material substantially filling the bore around the wire tension member and self-bonded to the surface of the bore over Substantially the entire length of the wire tension member, said wire having means for anchoring the opposite ends thereof in said bonding material.
Claim 2
Dependent Claim 159 words
A wooden handle for the head of an impact tool such as a hammer or the like having means for strengthening the handle against the effects of over-blows, said means comprising an elongated bore leading from an end of said handle adapted to receive the head of said tool and along a substantial portion of the length of the handle, an elongated metal wire tension member extending in the bore from the vicinity of said end and substantially along the length of said bore for a distance substantially more than twice the corresponding dimension of said head, said bore having a cross-sectional area several times the cross-sectional area of said tension member, and an epoxy resin bonding material substantially filling the bore around the wire tension member and self-bonded to the surface of the bore over Substantially the entire length of the wire tension member, said wire having means for anchoring the opposite ends thereof in said bonding material.
Claim 3
Dependent Claim 19 words
A handle in accordance with claim 1, wherein said anchoring means comprises bent ends of said wire tension member.
Claim 4
Dependent Claim 31 words
A handle in accordance with claim 1, wherein said bore is of the order of 1/4 to 5/16 inch in diameter and extends along about 1/2 the length of the handle.
Claim 5
Dependent Claim 171 words
An impact tool comprising a head having a hole therein, a wooden handle having one end inserted in said hole and secured to said head, and means for strengthening said handle against the effects of over-blows, said means comprising an elongated bore leading from said one end of said handle along the length thereof, an elongated tension member extending in the bore along the length thereof, the length of said bore and said tension member being substantially more than twice the corresponding dimension of said head, said bore having a cross-sectional area several times the cross-sectional area of the tension member, and an epoxy resin bonding material substantially filling the bore around the tension member and self-bonded to the surface of the bore over substantially the entire length of the tension member, said tension member having means for anchoring opposite ends thereof in said bonding material with one end locked in bonding material in said head and the other end locked in bonding material in said bore remote from said head.
Claim 6
Dependent Claim 171 words
An impact tool comprising a head having a hole therein, a wooden handle having one end inserted in said hole and secured to said head, and means for strengthening said handle against the effects of over-blows, said means comprising an elongated bore leading from said one end of said handle along the length thereof, an elongated tension member extending in the bore along the length thereof, the length of said bore and said tension member being substantially more than twice the corresponding dimension of said head, said bore having a cross-sectional area several times the cross-sectional area of the tension member, and an epoxy resin bonding material substantially filling the bore around the tension member and self-bonded to the surface of the bore over substantially the entire length of the tension member, said tension member having means for anchoring opposite ends thereof in said bonding material with one end locked in bonding material in said head and the other end locked in bonding material in said bore remote from said head.
Claim 7
Dependent Claim 15 words
A tool in accordance with claim 4, wherein said tension member is a metal wire.
Claim 8
Dependent Claim 17 words
A tool in accordance with claim 5, wherein said anchoring means comprises bent ends of said wire.
