<p>571,255. Ships' hulls. NEWTON, E. P. (Odenbach Holding Corporation). Aug. 4, 1943, No. 12610. [Class 113 (ii)] A method of constructing an end portion of a ship's hull consists in forming an open-ended tubular structure 20 corresponding in crosssection to the amidship portion, cutting approximately triangular pieces 26 . . . 29 from oppositely-disposed walls 21, bending certain of the projections 30, 31 so left into contact with the other projections 32, 33, and joining the contacting projections together. One cutting line of each triangle 26 . . . 29 passes through the centre of curvature of the adjacent rounded corner of the structure 20, and sector-shaped pieces are removed to prevent buckling. The bending is effected by hydraulic jacks or tackle blocks, and the joining by welds. A flat bar header may be used between the contacting edges. By making the triangles 28, 29 larger than the triangles 26, 27, an overhang deck is obtained, as shown in Fig. 9, wherein an extreme bow or stern section 55 has been added. Alternatively, flat end plates may be employed. An open-topped tubular structure 20 may be used to obtain an undecked hull. Specification 464,837 and U.S.A. Specification. 2,279,091 are referred to.</p> |
