Abstract

209,828. Trevorrow, J. H. L. Oct. 17, 1922. Steam generators. - Hollow metal bodies of rectilinear cross section such as steam boiler headers are made weldless throughout by working the open end of a blank a of rectilinear cross-section to rounded form and then bringing this end c to a domed form provided with a substantially central opening. The open end of the blank is acted on while hot by a die d the crosssection of which gradually merges from a rectangle to an ellipse, a plug e of oval section lying within the open end. A series of cupping-dies such as f, Fig. 5, is then driven on to the end of the blank to reduce the opening to circular form. The blank is then acted on bv a die of circular cross section and hemispherical end, bringing the open end to the shape shown in Fig. 1.
