Abstract

555,804. Riveting. RUDDICK, R., HATFIELD, S. J., and BRITISH UNITED SHOE MACHINERY CO., Ltd. March 4, 1942, No. 2832. [Class 43] [Also in Group XXII] A mandrel for use in riveting, of the kind described in Specifications 501,415 and 504,928, is of tapering form at the surface 11 of the head remote from the stem, to assist threading of the mandril head into a hole in the work, and of flat discoidal form adjacent the stem portion. The stem has a more or less elliptical cross-section at the locality of the constriction where the stem is intended to be broken off. To make the mandrel the wire stock is fed between dies 13, which close on it to form the constriction, the stock is severed to leave a predetermined length projecting beyond the dies, and this portion is acted on by a heading tool 21 to form the head.
