Patent number: 10995568Abstract: Sucker rods include end fittings having an outer wedge portion proximate to an open end, an inner wedge portion proximate to a closed end, and an intermediate wedge portion between the outer and inner wedges. Each wedge includes a leading edge, a trailing edge, and an angle between the leading and trailing edges. The triangular configuration, length of the leading edge, the length of the trailing edge, and size of the angle in each wedge portion cause distribution of force, such that compressive forces distributed to the rod proximate the closed end exceed compressive forces distributed to the rod proximate the open end. An automated installation procedure installs the end fitting through the use of multiple chucks, positioned by servo motors along a fitting table.Type: GrantFiled: August 19, 2019Date of Patent: May 4, 2021Assignee: Finalrod IP, LLCInventor: Russell P. Rutledge

Patent number: 10738546Abstract: A guide for sucker rods comprises a cylindrical shape including an orifice for the sucker rod and four protrusions extending outwardly therefrom. The guide utilizes a symmetrical two-piece design wherein each piece comprises a semi-cylindrical shape, with one full protrusion extending the length of the guide and two half protrusions extending half the length of the guide and also beyond the semi-cylindrical profile. These two pieces are attached to each other by means of an interference fit between two pairs of interlock surfaces, one pair of which is located on the inner surface of the portion of the half-protrusions extending beyond the semi-cylindrical profile, and the other pair of which is located on the outer surface of the guide on the opposite side from the two half protrusions. Epoxy is injected into grooves along the internal surface of the cylindrical shape by means of ports extending through the rod guide.Type: GrantFiled: December 23, 2019Date of Patent: August 11, 2020Assignee: Finalrod IP, LLCInventor: Russell P.

Patent number: 8500943Abstract: A continuous composite fiberglass sucker rod for connection between a pump and a pump drive has a rectangular cross section. End fittings having a rod receiving cavity are connected to the rod ends using a curable adhesive. The rod fitting is maintained in a vertical position with the cavity facing upwardly. The rod end portion is positioned in the cavity with the end at the bottom of the cavity. Curable adhesive is introduced into the cavity. A centralizer bushing is used to maintain alignment of the rod relative to the cavity. A portable heating device receives the fitting and rod end portion and enhances the curing process.Type: GrantFiled: November 10, 2011Date of Patent: August 6, 2013Assignee: John Crane Production Solutions Inc.Inventor: Russell P.

Patent number: 8062463Abstract: An improved design and a method of assembly of end fittings to sucker rods which may be of conventional length or continuous sucker rods is described herein. The end fittings and rods are assembled so as to form wedges which enhance the connectability of the end fitting to the rod, and further, the wedge or wedges approach the rod asymptotically so as to avoid any abrupt discontinuities in the wedge or wedges thus substantially eliminating stress concentration areas and potential failure areas in the rod. The assembly method provides for integrity in the rod to end fitting assembly to promote longer connection life and fewer shop rejections and field failures.Type: GrantFiled: March 5, 2007Date of Patent: November 22, 2011Assignee: Fiberod, Inc.Inventors: Russell P.
