Abstract

216,645. Vidal, A. E., (Rockwood Sprinkler Co.). April 17, 1923. Capsules, caps, and like cupped articles; bearings. - Cylindrical articles having different portions of varying diameter, such as bolster cases for spinning-spindles, are made by cupping a flat blank and then drawing down the ends thereof. The blank is brought to the form shown in Fig. 6 in stages and is then placed on a fixed mandrel 25, Fig. 14, and acted on by a die 17 carried by a press, to reduce the end B and force the end A into a reducing-die 13. This operation is repeated with smaller dies &c. and then the blank is inserted in a holder 32, Fig. 15, and a flange D<2>, with or without ribs F, Fig. 10, is upset by a die 30. The parts 23 and 35 are ejectors. A malleable iron cup 40, Fig. 12, is then cast or screwed on or secured by swaging down a flange H. A key notch 39 may also be stamped in the end A.
