Abstract

617,140. Jointing by stamping. STANDARD TELEPHONES & CABLES, Ltd. Sept. 20, 1946, No. 28302. Convention date, Sept. 24, 1945. [Class 83 (iv)] [Also in Group XXXVII] Insulating studs 3 are mounted on blade springs 1 by forming an aperture in the spring with marginal extrusion of the metal 4, placing the stud within the aperture, Fig. 2, and then, by means of an annular punch and die, compressing the metal extrusion 4 so that it is displaced inwardly into compressive engagement with the stud. The stud may be of hard rubber or phenol fibre composition and is deformed in the process, Fig. 4.
