Abstract

660,418. Making hollow-ware. JACOBSEN, O. May 13, 1949, No. 12818/49. Class 83 (ii). Spherically-curved metal plates for pressure vessels are built up from sections B of curved hexagonal shape combined with sections A of curved pentagonal shape arranged as shown in Fig. 1b, the included angles between adjacent sides being such that the sections can be welded together along the butting edges. The plane hexagonal and pentagonal section blanks are cut to the dimensions shown in Figs. 2 and 3, the letter R representing the radius of the circle circumscribing the hexagons and pentagons and the blanks are then pressed to the curvature given in the above Figures. In ball shells of large dimensions each section may itself be built up from curved hexagonal and pentagonal sections welded together. The hexagonal sections may be of regular equilateral shape or as indicated in Fig. 4. The invention is applicable to the manufacture of spherical, hemi-spherical or part-hemispherical shapes, e.g. a ball cap or ball skirt.
