Abstract
1410825 Electric horns ROBERT BOSCH GmbH 20 Oct 1972 [23 Oct 1971] 48348/72 Heading G5J An electromagnetic horn has a vibrator contact assembly 28, which is fastened by rivet 36 on to an inclined seating plane 55, formed into the annular face 53 of the housing 11. The leaf spring 29, carrying contact 30, is deflected by vibration movements of armature 45, which becomes attracted towards core 15 by electromagnet 14. The bridge member 32, carrying contact 31, is adjustable into a set position by set screw 35 and compression spring 60, acting on nut 34, which is insulated by adhering plastics material 58. Before assembly, spring 29 and bridge 32 extend in straight form, as indicated in Fig. 3 by broken lines, and their deflection into the assembled position sets up pressure between the contacts 30, 31.
