Opinion

ALMOND, Judge.

Appellant Chamblee appeals from the decision of the Patent Office Board of Appeals affirming rejection of claims 1 to 7 inclusive, of his application 1 entitled “Pipe Hanger Assemblies and Methods of Running and Removing Multiple Strings in Well Bores.” Claims 8 to 11, directed to a method of running a plurality of well pipe strings and packers into a well bore, were allowed by the examiner.

The application drawings, reproduced below, disclose a centrally apertured base A comprising two semi-circular sections 10, 11 connected by hinge 10a to provide a tapered aperture 17 into which is inserted a split hanger assembly unit B having three segments 18, 19, and 20 recessed at 18a, b; 19a, b, and 20a, b (Fig 3), to form three openings 23, 24 and 25. Assembly B has a plurality of string gripping slip elements C disposed in openings 23, 24, 25. The slip elements C are composed of segmental members 28 (Fig. 4) hinged together and arranged to be opened by means of a handle 27.
