Abstract

462,704. Pipe - end closing. BIGINELLI, O. Jan. 24, 1936, No. 2340. Convention date, May 23, 1935. Addition to 433,829. [Classes 83 (ii) and 83 (iv)] Forging; making bottles and cartridge-cases.- The method of forming a thickened closed end on a tube according to the parent Specification is modified by the provision of an independent source of heat for heating the end of the tube to be deformed. A tube 11 is placed between a forming-tool 1 and a counter-tool 7 and die 6, the end being upset and closed by movement of the tool 1. A source of heat 8, such as electrical means or hot gases, is enclosed in an insulating cover 10, and heats the tube through a T- section ring 9 engaging the die 6. Cartridge cases or gas bottles may be so produced.
