Patent number: 7013567Abstract: A pipe cutter comprises a rotary head having an axis of rotation, and a housing gear is coaxial with the rotary head such that the housing gear and rotary head have a common axis of rotation. A pipe slot extends into the rotary head and the housing gear, and a pipe cradle is provided in the pipe slot, and serves to receive a pipe. A cutting wheel is associated with the rotary head and a wheel biasing member urges the cutting wheel to extend into the pipe slot. A primary drive source is operatively connected to the housing gear by a gear system that rotates the housing gear and the rotary head about the common axis of rotation. Because the cutting wheel is biased to extend into the pipe slot and contacts a pipe placed therein, the cutting wheel revolves around the pipe and cuts into the pipe during rotation of the rotary head. The primary drive source may be manual or automated.Type: GrantFiled: October 27, 2003Date of Patent: March 21, 2006Inventor: Kent J. Myers

Patent number: 4302958Abstract: The invention relates to methods and apparatus for making rings from tube stock (10) by a part-off rolling tool (12,15) which is advanced radially into the tube stock to form successive rings, e.g. annular blanks for subsequent roll forming into bearing rings. The tube stock is indexed forward after separation of each ring. Errors in the length of tube stock indexed forward each time are contained by forming a locating groove (47) on the tube stock by means of a groove-rolling tool (40) set at an appropriate axial distance from the part-off rolling tool (12) and moved radially with it. In the next cycle the groove (47) automatically centers the part-off tool as the latter begins its advance into the tube stock, so as to give the correct axial length of the finished ring. The part-off tool is stopped before fully penetrating the tube wall, which is then machined. Final separation takes place during this machining or in a subsequent finishing pass by the part-off tool.Type: GrantFiled: December 26, 1979Date of Patent: December 1, 1981Assignee: Formflo LimitedInventors: Ronald C.
