Patent number: 8123106Abstract: An external weld bead is removed and processed from a welded pipe traveling in a downstream direction. The weld bead is separated from the pipe, allowed to flow in a downstream direction, and is guided downstream and cut into chips at a location downstream of where the weld bead is separated from the pipe. Also disclosed is weld bead cutting tool including a cutting edge at an upstream end of the tool, a guide feature disposed downstream of the cutting edge and extending toward a downstream end of the tool, wherein the guide feature widens from the upstream end toward the downstream end.Type: GrantFiled: June 9, 2011Date of Patent: February 28, 2012Assignee: Lumco Manufacturing CompanyInventor: Patrick J.

Patent number: 7695224Abstract: Methods of producing a pipe include curling a skelp into a cylindrical shape by bringing laterally opposed edges of the skelp together to form a seam, butt welding the seam to define the pipe downstream of the skelp, thereby leaving a radially inwardly extending weld bead. The weld bead is deburred off the pipe according to a depth of cut of a cutting tool. The depth of cut may be adjusted during deburring, and/or rotation of the cutting tool may be adjusted during deburring. The methods may be carried out using one or both of an adjustment device carried by a housing to pivot an adjustment member for adjustment of an upstream guide to adjust a depth of cut of the cutting tool into the weld bead, or an adjustment device carried by the housing and coupled to the cutting tool to rotate the cutting tool during deburring.Type: GrantFiled: January 31, 2008Date of Patent: April 13, 2010Assignee: Lumco Manufacturing CompanyInventor: Patrick J. Gleason

Patent number: RE28896Abstract: A cutting tool assembly comprising a cutter body which mounts at each of its opposite sides on one end and at the proper cutting angles a relatively narrow rectangular shaped cutter blade and a triangular shaped cutter blade. These cutter blades are maintained in an operative position in engagement with each other by a clamping element that is releasably joined to the cutter body at an angle that is related to the cutter cutting angles. Support and locking provisions further facilitate maintaining this operative position. Between these cutter blades a holder for another cutter blade is supported on the cutter body. This latter cutter blade and the triangular shaped blades are aligned along with the rectangular shaped cutter blades so as to machine a plural surface profile on a work piece.Type: GrantFiled: June 13, 1974Date of Patent: July 13, 1976Assignee: Lumco Manufacturing CompanyInventor: Patrick J.
