Patent number: 11597018Abstract: A tool for removing a coating from an end of a coated conduit comprising a metallic conduit having an outer diameter and a polymeric material applied over the outer diameter thereof is provided. The tool comprises: a guide member having an outer diameter sized to fit within an internal diameter of the metallic conduit; and a cylindrical cutting member having a substantially closed first end rotatably connected to an arbor, a substantially open second end, and a plurality of teeth elements. The cylindrical cutting member has an inner diameter that is substantially equal to the outer diameter of the metallic conduit such that when the cylindrical cutting member is rotated, the teeth elements remove the polymeric material from the outer diameter of the metallic conduit.Type: GrantFiled: November 11, 2020Date of Patent: March 7, 2023Assignee: Robroy Industries—Texas, LLCInventors: Steven A. Voelzke, Terry Henry, Amanda Lynn Kessel

Patent number: 11597020Abstract: A saw support assembly includes a base member defining a receiving channel. The receiving channel of the base member is configured to receive a leg of a saw therein to secure the base member to the leg of the saw. An arm member is pivotably coupled to the base member. The arm member is configured to pivot towards or away from the base member. The arm member is configured to extend from the base member to support the leg of the saw to which the base member is secured. A branch member extends between the base member and the arm member. The branch member defines a first end connected with the base member and a second end connected with the support arm. The branch member is configured to limit a degree to which the arm member can pivot away from the base member.Type: GrantFiled: February 18, 2022Date of Patent: March 7, 2023Inventor: Sean Radigan

Patent number: 11597021Abstract: A hobbing machine is disclosed having a workpiece spindle, by means of which a workpiece can be rotated about a workpiece axis, a hobbing head, at least one chamfering device, a first slide with a first slide guide system, wherein the hobbing head is arranged on the first slide, and a rail system. The first slide, by means of its first slide guide system, is arranged in a displaceable manner on the rail system. The hobbing machine also has a second slide with a second slide guide system. The at least one chamfering device is arranged on the second slide. Also, the second slide, by means of its second slide guide system, is arranged in a displaceable manner on the rail system, such that the first slide and the second slide can be displaced on an identical portion of the rail system. Presented is a structurally simple hobbing machine by means of which a workpiece can be hobbed and chamfered in a short period of time.Type: GrantFiled: February 3, 2020Date of Patent: March 7, 2023Assignee: Felsomat GmbH & Co. KGInventor: Jürgen Peschina
