Patent number: 9212078Abstract: A vertical individual section (I.S.) machine for manufacturing glass containers is disclosed in which parisons made in parison molds are lowered into blow molds located under the parison molds without being inverted, where they are blown into glass containers. Optionally, reheat shrouds may be located vertically intermediate the blank molds and the blow molds to reheat the parisons prior to them being blown. The vertical I.S. machine may have multiple sections that are located close adjacent each other, with each section potentially having multiple blank and blow molds.Type: GrantFiled: September 23, 2013Date of Patent: December 15, 2015Assignee: Emhart Glass S.A.Inventors: Kenneth L. Bratton, F. Alan Fenton, Matthew R. Hyre, Paul Stargardter, Jonathon S. Simon, Stephen A. Austin, Steven J. Pinkerton

Patent number: 8839644Abstract: A method of manufacturing of strengthened glass containers, and more particularly a method of thermally strengthening glass containers in a glass container manufacturing line at a location intermediate the hot end and the cold end. Glass containers formed at an I. S. machine are conveyed through a special tempering Lehr that heats them uniformly to a high temperature that is short of temperatures at which they may become deformed. Subsequently, the glass containers are subjected to a unique rapid thermal strengthening cooling process in which the outer and inner surfaces including all areas of the glass containers are simultaneously cooled to a temperature below the Strain Point of the glass used in the glass containers.Type: GrantFiled: May 24, 2011Date of Patent: September 23, 2014Assignee: Emhart Glass S.A.Inventors: Steven J. Brown, Timothy A. Ringuette, Kenneth L. Bratton, Steven J. Pinkerton, Matthew R. Hyre

Patent number: 6857291Abstract: A blow mold assembly for an I.S. machine for blowing a parison of glass and cooling the blown parison into a formed bottle which can be removed from the blow mold. A blow head is lowered onto a blow mold and final air is applied. A predetermined time after the blow head engages the top surface of the blow mold the blow head is lifted a selected vertical distance above the top surface of the blow mold to an exhaust position allowing cooling air to escape from the blow mold. The selected vertical distance is selected so that at least a minimum pressure will continue within the formed bottle. The blow head is maintain at the exhaust position for a predetermined time and then retracted. The selected vertical distance and the predetermined time can be set as desired.Type: GrantFiled: December 5, 2001Date of Patent: February 22, 2005Assignee: Emhart Glass S.A.Inventors: Leo Diehm, F.
