Patent number: 8650740Abstract: A method for making a collated fastener assembly includes arranging a plurality of fasteners in a row parallel to one another, in a plane, and spaced from one another, preheating the fasteners, applying a molten polymer material onto the fasteners and conveying the fasteners with the polymer into a mold cavity. The fasteners are maintained in the plane. The polymer is molded onto the fasteners and between adjacent fasteners to form a molding having a collar encircling a shank of each fastener and a connecting portion between adjacent fasteners. The molding maintains the space between the fasteners. A cooling stream is introduced onto the fasteners and the molding as the fasteners and the molding exit from the mold cavity.Type: GrantFiled: October 11, 2011Date of Patent: February 18, 2014Assignee: Illinois Tool Works Inc.Inventors: Isaac H. Heskel, Lawrence S. Shelton, Donald E. Bergstrom, Michael J. Christensen, Algis P. Suopys, Eldrige J. Presnell, Joseph J. Righter, Jr., Richard W. Mrozik, Jr.

Patent number: 8033005Abstract: A method for making a collated fastener assembly includes the steps of arranging a plurality of fasteners each having a head and a tip, in a row parallel to one another, the fasteners being arranged in a plane. The plurality of fasteners are preheated to elevate the temperature of the fasteners and a molten polymer material is applied onto the preheated plurality of fasteners. The fasteners, maintained in the plane, are conveyed with the molten polymer thereon between a pair of forming wheels. The molten polymer material is molded onto the preheated fasteners and between adjacent fasteners to form a plastic molding having a collar encircling a shank of each fastener and a connecting portion between adjacent fasteners. A cooling vapor is sprayed onto the fasteners and the plastic molding as the fasteners and the plastic molding exit from between the molding wheels. A gaseous cooling stream is forced over the fasteners and the plastic molding to cool the strip to form the fastener assembly.Type: GrantFiled: November 30, 2009Date of Patent: October 11, 2011Assignee: Illinois Tool Works Inc.Inventors: Isaac H.

Publication number: 20110083396Abstract: A fastener is configured for securing a lath to a surface for, for example, the application of stucco to the surface. The fastener includes a fastener having a head, a shank and a penetrating tip. The head has a diameter and the shank has a diameter less than the head diameter. The stucco fastener has a sealing/spacer assembly having spacer element and a sealing element. The spacer element is formed from a relatively incompressible material and has a diameter greater than the shank diameter. The spacer element has a bore therein having a diameter about equal to the shank diameter. The sealing element is formed from a resilient, water-resistant material and is positioned adjacent to and in contact with the spacer element. When the fastener is driven into the surface, the fastener penetrates the surface to secure the fastener to the surface and a portion of the lath is captured between the head of the fastener and the spacer element to space the lath from the surface.Type: ApplicationFiled: September 30, 2010Publication date: April 14, 2011Applicant: ILLINOIS TOOL WORKS INC.Inventors: Lawrence S.

Patent number: 7845889Abstract: A nail having a plurality of grooves configured to reduce the amount of material needed to create the nail and increase the holding power of the nail, while only minimally affecting the bending yield strength of the nail and other important properties. The nail includes a relatively high number of grooves having a relatively shallow depth to retain a cross-sectional geometry of the shank that permits the formation of a full round head of sufficiently large diameter such that pull through resistance of the nail is not significantly affected. Various embodiments of such a nail are disclosed. In a first embodiment, the grooves are semi-circular and are disposed evenly and symmetrically about the circumference of the shank. In a second embodiment, a protrusion is formed at one tangent point (corner) of each of the plurality of grooves. In a third embodiment, a protrusion is formed at each tangent point of each of the plurality of grooves.Type: GrantFiled: December 18, 2007Date of Patent: December 7, 2010Assignee: Illinois Tool Works Inc.Inventors: Lawrence S.

Patent number: 5749692Abstract: A fastener is formed from carbon steel wire so as to have an elongate shank defining an axis, an enlarged head formed at one end of the shank, and a generally pointed tip formed at the other end of the shank. The shank has a ringed portion formed with annular grooves defining annular rings and with helical grooves intersecting the annular grooves and defining helical ribs. The fastener is heat-treated, zinc-plated, and chromate-coated. Substantially all of the shank or of the fastener, as a whole, is further coated with a polymeric material to resist corrosion, to improve ease of driving the fastener, and to increase holding power of the fastener when driven through a wood, plywood, or plasterboard workpiece and then through a steel framing member. Substantially all of the shank or of the fastener, as a whole, may be thus coated with the polymeric material. The polymeric material softens and flows upon penetration and rehardens.Type: GrantFiled: June 5, 1997Date of Patent: May 12, 1998Assignee: Illinois Tool Works Inc.Inventors: Frederick A. Kish, Elizabeth J. Eckmann, Lawrence S. Shelton

Patent number: 5642974Abstract: A building assembly comprises a wooden board, a metal framing member, and a fastener having an elongate shank, an enlarged head, and a generally pointed end and fastening the board to the framing member. The shank has a ringed portion with annular grooves defining annular rings having a uniform, outer diameter, helical grooves intersecting the annular grooves, a cylindrical land having a smaller diameter and dividing the ringed portion into an axially longer subportion nearer to the tip and an axially shorter subportion nearer the head, a cylindrical land between the tip and the ringed portion, and a cylindrical land between the head and the ringed portion. The fastener is driven through the board and through the framing member wall so that the head bears against the board, so that the tip and the shank form, from the wall of the framing member, a generally annular lip projecting toward the tip and so that the lip is disposed around the cylindrical land dividing the ringed portion.Type: GrantFiled: December 12, 1995Date of Patent: July 1, 1997Assignee: Illinois Tool Works Inc.Inventors: William L. Gabriel, Lawrence S. Shelton, Henry A. Sygnator, Elizabeth J. Eckmann
