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.

Patent number: 7422399Abstract: A debeading tool capable of internally debeading butt-welded pipe made of PVC and similarly hard plastics has a work head that can be coupled to a distal end of a torque tube. The work head includes a motor carrying a cutter which is oriented at an angle, e.g., 12 degrees, to the interior pipe wall for cutting the weld bead as the tool is rotated inside the pipe. The work head cutter can be moved between an insertion/removal position away from the side wall and a cutting position against the bead on the side wall. A locator assembly that contacts the bead during insertion of the work head aids in positioning the cutter to straddle the weld bead. A pipe cleaner can be prepositioned in the pipe before butt-welding to be engaged upon removal of the work head to pull weld bead chips and fines from the pipe.Type: GrantFiled: September 13, 2006Date of Patent: September 9, 2008Inventors: Rolland Edward Salsberry, Randle Flick Salsberry

Patent number: 5435676Abstract: A method and apparatus for broaching a series of axially aligned and spaced bores in which a first broach is provided for broaching in an initial operation. The first broach has circumferentially extending cutting teeth. The first broach also has arcuately spaced, longitudinally extending grooves which cross the cutting teeth and divide the cutting teeth into arcuate segments. Broach guides in the spaces between bores have ribs arranged in the same arcuately spaced relation as the grooves about an axis coinciding with the aligned axes of the bores. The first broach is advanced through the bores with the ribs slidably received in the grooves to guide the first broach and the cutting segments, broaching arcuately spaced sectors of the bores but leaving unbroached ridges therebetween. A second broach broaches the ridges left by the first broach.Type: GrantFiled: January 19, 1994Date of Patent: July 25, 1995Assignee: National Broach & Machine CompanyInventors: Harvey J.

Patent number: 5323949Abstract: The invention comprises a method and apparatus for handling the weld bead scarfed from the interior surface of continuous seam welded metal tube or pipe incident to its manufacture. A section of tube of predetermined length is cut from the lead and of the advancing continuous tube, having the scarfed weld bead therein, by a rotary cutter. The speed of the individual section is increased to create a gap between the individual section and the continuous tube, and a scissor mechanism severs the weld bead within the gap. The severed section of weld bead is then conveyed within the associated individual section of tube to a tube accumulation or storage area for removal and disposal.Type: GrantFiled: June 23, 1993Date of Patent: June 28, 1994Assignee: Abbey Etna Machine CompanyInventors: Lewis H. Ruple, George W. Kaase

Patent number: 5216792Abstract: An arrangement for trimming short shavings from a seam inside a longitudinally welded pipe having a longitudinal axis, in which an inside shaving is scraped off continuously with a stationary blade by moving the pipe relative to the blade. The inside shaving is then cut up discontinuously with an actuated knife inside the pipe. The scraping procedure is carried out with scraping forces having a resultant force vector lying substantially in a plane through the longitudinal axis of the pipe and the seam. The scraping procedure is dependent on the speed of the moving pipe, whereas the cutting procedure is independent of the speed of the moving pipe.Type: GrantFiled: June 2, 1992Date of Patent: June 8, 1993Assignee: Hoesch AktiengesellschaftInventors: Bernd Engler, Helmut Will

Patent number: 5201622Abstract: A train apparatus for removing thick blister buildups from an underground fiber conduit used for housing power cables. The train apparatus includes three or more cutting units including an initial, a middle and a final cutting unit having smallest, medium and largest overall cutting diameters respectively. Each cutting unit having a lead guide and six cutting stars each having four cutting blades where the cutting blades on one cutting star are offset with the cutting blades on the other cutting stars. When pulled through the fiber conduit, the lead guide of the cutting units will prevent the cutting unit from going off the center of the conduit and digging itself into the interior sidewall of the conduit. The initial, middle and final cutting units will remove respectively the surface, the intermediate and the underneath portions sequentially.Type: GrantFiled: August 5, 1991Date of Patent: April 13, 1993Assignee: Robert P.
