Abstract
451,838. Making pipe elbows. CORNELL, E. S., 17, Campbell Lane, Larchmont, New York, U.S.A. March 20, 1936, No. 8424. Addition to 412,075. [Classes 83 (ii) and 83 (iv)] Angular bending.-In bending wrought copper elbows, a tube 20 with normal edges is pushed by a stepped punch 8 into a split die 6 with an angular part forming an offset abutment. Sockets may be formed on the elbows by enclosing the elbow within a split die and expanding the ends in succession by a punch. The punch 8 carries a pivoted ball 33 for preventing collapse of the inner wall. After formation the elbow is secured in a clamp and the ends are squared by a saw. The bore of the elbow is trued by passing therethrough balls of increasing diameter.
