Patent number: 7073495Abstract: A concrete cutting saw has wheels and a rotating cutting blade that cuts a groove in the concrete surface. A support is mounted to the saw to support the concrete surface adjacent the cutting blade to reduce raveling. One or more nozzles are mounted to the saw and in fluid communication with a gas source to provide a gas stream directed toward the support so the gas stream from the nozzle impinges on a leading end of the support. The one or more nozzles are located adjacent to and in front of a leading end of the support, and preferably blow on opposing sides of the plane containing the cutting blade.Type: GrantFiled: August 31, 2005Date of Patent: July 11, 2006Assignee: Soff-Cut International, Inc.Inventor: Charles E. Markley

Patent number: 6990972Abstract: A concrete saw has a rotating cutting blade that rotates in a first plane to cut a groove in a concrete surface. The blade is guided along that groove by two guides. A rolling or sliding support member on opposing sides of each guide roll or side along the concrete to support the saw blade on the concrete and to position the blade relative to the concrete. The guides and rollers are advantageously on opposing sides of the blade. The guide can be a sliding member but is preferably a rolling disc sandwiched between two rolling supports. A diverter can prevent debris from the blade from getting under the movable support.Type: GrantFiled: February 11, 2004Date of Patent: January 31, 2006Assignee: Soff-Cut International, Inc.Inventor: Charles E.

Publication number: 20040031475Abstract: A portable concrete saw has a rotating concrete cutting blade that is rotated about a rotational axis by rotating drive shaft mounted to the saw and driven by a motor on the saw. A threaded recess in a distal end of the drive shaft is aligned parallel to the rotational axis but offset from that axis. An arbor sleeve is mounted to rotates with the distal end of the drive shaft. The sleeve has a non-symmetric blade mounting portion thereon to orientate the cutting blade in only one orientation. The sleeve has a hole therethrough parallel to the rotational axis through which the distal end of the shaft extends. A clamping plate has a recess aligned with and configured to receive at least one portion of the blade mounting portion in order to align the plate to rotate about the rotational axis. The plate has a geometric center with a hole through the plate parallel to the rotational axis but offset from the geometric center.Type: ApplicationFiled: August 16, 2002Publication date: February 19, 2004Inventor: Charles E. Markley

Patent number: 5749353Abstract: A saw blade is provided which includes an inner collar separated from an outer collar with a resilient isolated layer. The inner collar fastens to the arbor shaft of a driving motor, while the outer collar is welded to the rim containing hardened particles, such as diamond bits. The inner and outer collars form inner and outer collar flanges which receive the resilient isolating material therebetween. In an alternative embodiment, the inner and outer collars are separated from one another with a plurality of plugs formed of resilient isolating material. The plurality of plugs are formed in a circular pattern about the arbor shaft and are spaced apart from one another. In another embodiment, a vibration dampening coupler is fastened to the arbor shaft and formed separate from the cutting blade. The isolating resilient layer may be formed as a solid layer, as a plurality of O-rings, or with a void therein.Type: GrantFiled: September 30, 1996Date of Patent: May 12, 1998Assignee: Diamant Boart, Inc.Inventors: Charles E. Markley, Rick Younger

Patent number: 4390338Abstract: A blow pin assembly for use in blow molding extruded thermoplastic parisons is disclosed. The assembly provides a blow pin tip which effects forge formation of structure on the inside surface of the neck finish of the container. The blow pin assembly utilizes a rotation collar and a cutter collar to aid in removal of any neck moil associated with the blow molding procedure.Type: GrantFiled: November 18, 1981Date of Patent: June 28, 1983Assignee: Ethyl Development CorporationInventors: Kenneth E. Bowers, Charles E. Markley

Patent number: 4381183Abstract: An apparatus for removing a waste portion from a blow molded article is disclosed. The apparatus removes the waste portion while the article is enclosed within the blow mold and features a gripping structure for gripping the waste portion and a power assembly associated with the gripping structure to move the gripping structure from the article, thereby pulling the waste portion from its point of attachment with the article. The gripping structure includes two opposed gripping means which are arcuately movable about their respective pivot points. Each pivot point is laterally displaced from the gripping structure and positioned along a line extending through the shortest distance from the pivot point to that portion of the gripping structure which is closest to the attachment of the waste portion to the article.Type: GrantFiled: October 22, 1981Date of Patent: April 26, 1983Assignee: Ethyl Development CorporationInventors: Kenneth E. Bowers, Charles E. Markley
