Abstract

665,520. Tube expanders. CHAMPION, A. Aug. 9, 1950 [Aug. 9, 1949], No. 20680/49. Class 83 (iv). In a tube expander a tube is positioned against a flange 5, balls 10 are then projected by a conical mandrel 16 to form an expansion on the tube and to hold it in place while balls 11 form a bell mouth on the end of the tube. Specification 608,933 is referred to.
