Patent number: 8109405Abstract: A can end is provided, which includes a severable panel, a peripheral scoreline defining the periphery of the severable panel, an opening mechanism such as a pull tab, a rivet coupling the pull tab to the severable panel, and a rivet base scoreline in the public side of the severable panel within about 0.025 inch or less of the stem of the rivet. The rivet base scoreline includes an arcuate head portion, first and second arm portions extending from the arcuate head portion, and first and second ends. The base of the rivet has a radius of curvature forming an intersection between the stem of the rivet and the public side of the severable panel. The arcuate head portion of the rivet base scoreline is contiguous with the radius of curvature. The pull tab includes a nose portion having a number of apertures aligned with corresponding portions of the rivet base scoreline disposed thereunder.Type: GrantFiled: June 12, 2008Date of Patent: February 7, 2012Assignee: Stolle Machinery Company, LLCInventors: Gregory H.

Patent number: 7472575Abstract: A non-circular can end for a container having walls which form an opening includes a corner-mounted pull tab opener secured to a severable panel portion by an integral rivet. The corner-mounted opener facilitates easy opening of the can end. A pair of generally parallel bead recesses on either side of the integral rivet stiffen the severable panel portion in order to facilitate bending of the panel aft of the rivet to easily open the can end. The severable panel optionally further includes a mustache-shaped scoreline to reduce the amount of force required to lift the opener. Tooling and a conversion press for converting shells into the non-circular can ends are also disclosed.Type: GrantFiled: July 13, 2007Date of Patent: January 6, 2009Assignee: Stolle Machinery Company, LLCInventors: Gregory H. Butcher, Kenneth F. Fultz, Mark R. Mitchell, David A. Stradling, Greg S. Williams

Patent number: 6266992Abstract: A modular tooling system for use in combination with a conversion press has an upper base member adapted to be removably mounting into the conversion press, a tooling holder, a tooling insert and means for retaining the tooling insert within the tooling holder. The tooling holder is adapted for attachment to the upper base member. The tooling holder defines a chamber therein extending therethrough. The chamber includes a shoulder portion. The tooling insert is adapted to be removably mounted in the tool holder. The insert has a first end, a second end, and a shoulder portion adapted to cooperate with the tooling holder shoulder portion. Bushings and spacers secure the insert within the tooling holder. Both the tooling holder chamber and the tooling insert are of a predetermined cross section which are adapted to correspond with each other and define a keyed relationship.Type: GrantFiled: August 25, 1999Date of Patent: July 31, 2001Assignee: Alcoa Inc.Inventors: Gregory H. Butcher, Greg S. Williams

Patent number: 5798477Abstract: The present invention includes a small diameter explosive cartridge and a two-stage large diameter explosive cartridge apparatus for presplitting rock can be axially detonated by detonating cord through a central detonation passageway in the explosive cartridge while keeping the detonating cord and the explosive material in the explosive cartridge physically separate. The explosive cartridge includes an outer tube and an inner tube inside of the outer tube. The explosive cartridge includes two or more continuous webs extending radially between the outer surface of the inner tube and the inner surface of the outer tube. For the small diameter explosive cartridge, the space between the outer surface of the inner tube and the inner surface of the outer tube is filled with high explosive material such as water gel or emulsion explosive material.Type: GrantFiled: December 18, 1996Date of Patent: August 25, 1998Inventors: Richard W. Givens, Greg S. Williams
