Patent number: 8795034Abstract: A dressing blade for finishing and reconditioning new and used abrasive grinding and cutting tools has a slab-shaped shank with an extension protruding longitudinally from the shank. Superabrasive grains are disposed on the surface of the extension and held in place by a brazed metal composition. This composition is formed by brazing a powdered mixture of brazing metal components and active metal components. Specific extension configurations are provided which allow aligning the superabrasive grains in single layer arrangement for precise dressing and simple fabrication of the tool. The novel dressing tool exhibits excellent wear characteristics.Type: GrantFiled: December 5, 2007Date of Patent: August 5, 2014Assignee: Saint-Gobain Abrasives, Inc.Inventors: Richard M. Andrews, Sergej-Tomislav Buljan, Earl G. Geary, Jr., Robert L. Owen, Marcus R. Skeem

Patent number: 5983767Abstract: The present invention is a saw guiding device for guiding a power saw when cutting a workpiece in the form of either a flat board or an I-beam. The saw guiding device comprises a base member which is to be disposed across end caps of an I-beam. A straight saw guiding surface of the base member is configured such that a power saw can be engaged therewith and slidably moved therealong to thereby guide the power saw in a straight line as it cuts the I-beam. The base member includes an upwardly facing saw supporting surface disposed adjacent the straight saw guiding surface. The upwardly facing saw supporting surface is constructed and arranged to support the power saw as it is engaged with and slidably moved along the straight saw guiding surface between the end caps of the I-beam. The base member has a workpiece edge engaging structure extending downwardly therefrom. A movable workpiece edge engaging structure is constructed and arranged to be moved through a range of operative positions.Type: GrantFiled: March 27, 1998Date of Patent: November 16, 1999Assignee: The Stanley Works, Inc.Inventors: William D. DeFelice, Robert L. Owens

Patent number: 5878501Abstract: A fixed blade utility knife has a housing provided by a lower handle portion, an upper lever portion, and a nosepiece at one end thereof which seats one end of the handle and lever. The lever is pivotably supported on the nosepiece, and a blade holder in the nosepiece is pivotably supported on the handle. The blade is seated in the holder and extends outwardly of the nosepiece, and a blade guard of generally U-shaped cross section extends about the cutting edge and is slidable in the nosepiece to extend outwardly to sheathe the cutting edge and to be withdrawn into the nosepiece to expose the cutting edge. A manipulatable element slidably seated in the nosepiece is engaged with the blade guard to effect its sliding movement. Pivoting of the lever into an open position releases the blade from engagement in the holder so that it may be easily replaced.Type: GrantFiled: August 8, 1997Date of Patent: March 9, 1999Assignee: The Stanley WorksInventors: Robert L. Owens, Christopher J. Pigeon, Timothy O. Van Leeuwen

Patent number: 5493787Abstract: A casing for a chalk line dispenser comprises a pair of casing elements which interfit and define a chamber for storing chalk. The casing elements have end walls and sidewalls extending about the periphery thereof with interfitting surface portions along the outer ends thereof. The interfitting surface portion of one of the casing elements has a groove in the end surface of the sidewall extending about the periphery thereof and intermediate its width to provide resiliently deflectable depending wall sections. The interfitting surface portion on the other of the casing elements has a tongue extending about its periphery which seats in the groove and is of greater width than the groove to deflect the wall sections, so that the tongue is firmly gripped by the resiliently deflectable wall sections to provide a seal therebetween.Type: GrantFiled: December 21, 1994Date of Patent: February 27, 1996Assignee: The Stanley WorksInventor: Robert L. Owens

Patent number: 5406707Abstract: A utility knife has a handle providing a cavity and an opening at one end, and a slide seated in the cavity for sliding movement relative to the opening. Supported on the slide is a knife blade which moves therewith between a position within the cavity and a position projecting outwardly of the opening. The blade has a cutting edge extending along its lower edge, and the slide has a side wall against which the blade is disposed and a base wall upon which a portion of the cutting edge is disposed. The slide has a cam portion configured to produce a horizontal force component on the cutting edge portion of the blade when the cutting edge cuts into the base wall as a result of the cutting force applied by the user on the outwardly projecting blade.Type: GrantFiled: June 10, 1994Date of Patent: April 18, 1995Assignee: The Stanley WorksInventors: Robert L. Owens, W. Gregory Sawyer

Patent number: 4276526Abstract: A miniature current limiting circuit breaker incorporates double break circuit interrupting contacts capable of being abruptly separated by a high fault current responsive solenoid acting to first trip the breaker mechanism and then forcibly effect contact separation. The arc chamber is constructed to achieve enhanced blowout of the arc into the arc chute and to develop gas pressures acting to accelerate contact separation. The circuit breaker is trip-free and includes both thermal tripping and internal common tripping capabilities.Type: GrantFiled: January 23, 1980Date of Patent: June 30, 1981Assignee: General Electric CompanyInventors: Ronald D.
