Patent number: 5482420Abstract: A collated screw package is formed with a plurality of parallel screws secured to each other with two wires which are sufficiently friable to permit the screws to be singly detached from the package as the screw is driven by a rotary drilling device. The wires are preferably spot welded to unthreaded portions of each screw which prevents fragments of the wires and fragments of the spot welded joints from interfering with the screw threads. To form the unthreaded portions, the thread of each screw is interrupted for a portion to allow at least one of the wires to be secured to the screw shank at the interruption. The interruption is formed by a relief in a continuous surface of thread forming tooling.Type: GrantFiled: November 10, 1994Date of Patent: January 9, 1996Assignee: Illinois Tool Works Inc.Inventors: William L.

Patent number: 5195931Abstract: Nails having radially offset, circular heads are manufactured from a malleable wire. The wire is clamped so that a leading portion extends axially from a clamping mechanism. The extending portion is bent at an acute angle relative to a clamping axis. The extending portion is cut so as to form a pointed end thereon and so as to leave a bent stub extending at such an angle. Such a nail head is formed from the stub, which is pressed by a punch into a cavity defined by the clamping mechanism, and which is deformed when pressed thereinto. The cavity has a fully circular, offset margin. The punch has a face covering the cavity. Once released, the wire is fed axially until a leading portion extends as before. These operations are repeated to form a similar nail in each repetition. A novel apparatus for carrying out these operations is disclosed.Type: GrantFiled: February 7, 1992Date of Patent: March 23, 1993Assignee: Illinois Tool Works Inc.Inventors: Robert W.

Patent number: 5033181Abstract: Nails suitable for outdoor use, such as, for example, roofing nails, are formed from carbon steel wire precoated with a metallic layer, which has corrosion-resistant properties, such as, for example, a zinc layer applied by pre-galvanizing the stock carbon steel wire. Each nail is formed with a shank and with a head. The metallic layer is discontinuous within a region formed upon the head of each nail. The nails are collated by means of collating wires welded to the shanks of the nails. The collated nails are coiled. The coiled nails are cleaned in a cleaning bath, such as, for example, 1,1,trichloroethane. The cleaned nails are coated with a polymeric layer, which covers the region of the head of each nail where the metallic layer is discontinuous, thus restoring the corrosion-resistant properties of the nails.Type: GrantFiled: June 8, 1990Date of Patent: July 23, 1991Assignee: Illinois Tool Works Inc.Inventors: Geronimo Lat, William L.
