Patent number: 5542320Abstract: An accessory (10) for a wrench socket (12) is disclosed including a generally cylindrical magnet (32) secured to a generally cylindrical, nonmagnetic, compressible disk (26). Specifically, the magnet (32) is received in a recess (46) formed in the disk (26) and secured to the disk (26) by a layer (60) of a size larger than and extending over the face (36) of the magnet (32) and integrally secured around its entire periphery to the face (44) of the disk (26). The disk (26) snuggly fits within the well (14) and magnetically insulates the magnet (32) from the socket (12). The magnet (32) has a size smaller than the well (14) and is generally concentric within the well (14), with an air space being created between the magnet (32) and the well (14) for magnetically insulating the magnet (32) from the socket (12) in the most preferred form.Type: GrantFiled: June 28, 1995Date of Patent: August 6, 1996Assignee: Vasichek Enterprises LLCInventors: Richard A. Vasichek, Robert J. Vasichek, Dean S. Somerville, Mitchel D. Trostad

Patent number: 5375449Abstract: A method of forming a number of sizes of hollow shaft nutdrivers from a common size metal tube workpiece. The method comprises three steps to form a hex drive socket on one end of a metal tube workpiece, and a fourth step to form a plurality of raised wings on the other end of the metal tube workpiece for retaining the other end of the then finished nutdriver in a handle.Type: GrantFiled: January 11, 1994Date of Patent: December 27, 1994Assignee: A.T. & G. Company, Inc.Inventor: Fred A. Bononi

Patent number: 5359911Abstract: A lightweight self-insulating composite hand tool such as a screwdriver has a tool shank of electrically insulative material molded to and about a tip shank of a tool tip, having a working end and an integral tip shank. A mechanical interlock coupling is molded into the tip shank to resist axial tensile and compressive stress and torsional stress. A premolded replaceable elastomeric cover is slipped onto the hand tool and about the periphery of the molded tool shank. The working end of the tool tip includes a circumferential groove which receives a snap fitting bead of the replaceable elastomeric cover. The molded tool shank may be a braided composite of non-electrically conducting reinforcing filaments embedded within a settable matrix such as resin or epoxy. The tip shank is provided with an annular recess which flares rearwardly at a slight retention angle to retain the braided filaments and the settable matrix end of the composite tool shank on the tool tip shank.Type: GrantFiled: June 30, 1993Date of Patent: November 1, 1994Assignee: U.S. Composites Corp.Inventor: August H. Kruesi

Patent number: 5163345Abstract: A tool for rotatably driving a fastening member includes a hollow tubular shank having a socket coupled to one end thereof in communication therewith for receiving an associated rotatable fastener member. A helical compression spring is disposed coaxially within the shank, having the outer end thereof affixed to a magnet disposed for magnetic engagement with the fastening member received in the socket, and having an end coil at the other end thereof disposed outside the other end of the shank with an outer diameter greater than the inner diameter of the shank, the other end of the shank being received in a bore in a handle for cooperation therewith to trap the end coil of the spring, therebetween.Type: GrantFiled: February 25, 1992Date of Patent: November 17, 1992Assignee: Snap-on Tools CorporationInventors: Jimmy T. Doan, Scott W. Predny
