Patent number: 5622464Abstract: A screw for use with a washer as a sealing fastener having formations near the head of the screw to increase driving resistance when the portion having the formations reaches a surface into which the screw is being drilled. The screw includes a shank with a tip end and a head end. A head at the head end may be driven by a driving tool such as a pneumatic or electric drill. To facilitate retention of the washer the head has a flange that forms a recess. The shank has an enlarged portion near the head adjacent to the recess and the enlarged portion has ridges. The enlarged portion, including the ridges, increases the driving resistance of the screw. This increase in resistance gives notice to an operator of the driving tool that an appropriate driving depth and torque have been achieved. Preferably, the washer has an inner diameter surface with fully radiused projections.Type: GrantFiled: August 22, 1995Date of Patent: April 22, 1997Assignee: Illinois Tool Works Inc.Inventors: Michael C. Dill, James W. McElderry, Juergen O. Rathgeber

Patent number: 5605018Abstract: A flexible end cap includes at least one flexible membrane, such as a rubber sheet, for covering the end of the roof rib, having a top peripheral portion and a bottom peripheral portion. At least one frame member is attached to at least a portion of the top peripheral portion of the flexible membrane for supporting the membrane in a sealing relationship with the roof rib. At least a portion of the bottom peripheral portion, such as the portion for covering a ridge profile, includes at least two sealing ribs wherein a cross-sectional height of one rib is larger than a cross-sectional height of the other rib. The sealing ribs with the larger cross-sectional height allow the end cap to accommodate varying designs of roof rib profiles formed by adjacent sheets of roof panels.Type: GrantFiled: August 4, 1995Date of Patent: February 25, 1997Assignee: Illinois Tool Work Inc.Inventors: James W. McElderry, Michael C. Dill, Juergen O. Rathgeber, John A. Wand, John F. Fox

Patent number: 5469671Abstract: A composite roof covering securement element is comprised of an elongated rubber membrane onto which a plastic batten strip is adhesively bonded. The membrane and strip have a range of flexibility which permitts the same to be rolled into a coil for manual prepositioning on a roof and then unrolled to lie flat upon the roof for attachment along the perimeter. When installed the composite element resists shear loads and securely retains the overlying roof covering in place.Type: GrantFiled: March 9, 1994Date of Patent: November 28, 1995Assignee: Illinois Tool Works Inc.Inventors: Juergen O. Rathgeber, Frederick A. Kish, Syed R. Hasan, Craig A. Hindman

Patent number: 5419867Abstract: A seamless tube useful in making a roofing batten is extruded from a polymeric material consisting essentially of a major amount of poly(ethylene terephthalate) and a minor amount of at least one polyolefin, flattened in a vacuum sizer so as to define two plies, and milled and drawn so as to orient the tube longitudinally. As milled and drawn, the tube is oriented so as to have a tensile strength of at least about 25,000 psi in a longitudinal direction. The plies are punched so as to have holes therethrough at spaced intervals along the tube. When used to make a roofing batten to coact with conventional fasteners, such as roofing screws, the tube exhibits superior characteristics of split resistance and pull-through resistance.Type: GrantFiled: May 19, 1992Date of Patent: May 30, 1995Assignee: Illinois Tool Works Inc.Inventors: Donald L. Van Erden, Juergen O. Rathgeber, Parimal M. Vadhar, John P. Wojcik

Patent number: 5139379Abstract: An improved composite fastener comprised of an improved roofing screw and a roofing washer and useful to fasten a blanket of roofing insulation to a soft substrate. The screw shank has a leading portion and a locking portion. The locking portion has two locking tabs. The washer has an aperture with a margin coacting with the screw when it is driven through the washer. The screw becomes locked to such washer when the screw is driven sufficiently for its head to bear against the washer at which time the locking tabs engage the undersurface of the washer.Type: GrantFiled: October 29, 1990Date of Patent: August 18, 1992Assignee: Illinois Tool Works Inc.Inventors: Syed R.
