Abstract

861,774. Switch bases and covers. NAIMER, H. April 5, 1957 [April 23, 1956], No. 11247/57. Class 38 (5). [Also in Group XXV] A row of switches 10-10c, Fig. 1, are secured together by tie-bolts 15 made of a thermoplastically - deformable, electrically - insulating synthetic resin, e.g. a superpolyamide. The tie-bolt may be screwed at both ends to receive nuts. In a modification, the bolt 20, Fig. 5, has a head at one end and is screwed at the other. The flashes 23, formed by the halves of the injection mould in which the bolt is made, engage with and lock a co-operating nut. In yet another arrangement, the bolt 52, Fig. 6, has a head 52c at one end and a slot to receive a cotter 52b, at the other, and is tensioned after installation by relatively-turning rings 53, 54 which have interengaging oblique surfaces 55. Ring 54 is subsequently locked to the bolt head by adhering rings 53, 54 together with a heated rod applied at the edges of surface 55.
