Abstract

324,144. Jacobs, A. H., and Painter, G. Nov. 1, 1928. Spinning.-In spinning a hollow body the blank 6, Fig. 3, is expanded against the inner face of a hollow mould. The mould comprises two parts 1, 2 connected by studs 4 engaging bayonet-slots 5, the studs having flats so that, when turned slightly, they will lock the parts together. The tool 9, Fig. 1, is manipulated by racks 15, 19, pinions 14, 18, and levers 13, 17. A finishing stroke is made from the bottom to a groove 20 and then from the mouth to the same groove to cause the metal to flow into this groove.
