Abstract

552,185. Couplings combined with switches. CIANCHI, A. Dec. 2, 1941, No. 15513. [Class 38 (i)] [Also in Group XXXVII] A mercury or other enclosed switch D is mounted on a cover C carrying contacts E which are plugged into contacts B on a relatively-fixed casing A, and an electromagnet F1 which operates the switch D is mounted on an inner member G normally housed within but detachable from the casing A. The magnet poles F embrace the . mercury container and the magnet when energized displaces the mercury so that it bridges contacts connected to the contacts E. A fuse H<SP>2</SP> may be in series with the electromagnet F<SP>1</SP> and in a modification, Fig. 13 (not shown) a magazine fuse is in series with the mercury switch. In another modification, Fig. 12 (not shown) there are two electromagnets, one for closing the switch, which is then held latched, and the other for releasing the latch and so opening the switch. These magnets may also operate a sliding bolt which prevents the cover C being withdrawn when the switch is open. The contacts E are each formed from a U-shaped strip, the ends of which engage between a block B, Fig. 3, and spring fingers B<SP>1</SP>. In Fig. 9, the U-shaped contact strip J rests on knife edges J<SP>3</SP> and after insertion, rotation of a screw J<SP>1</SP> pulls down the centre of the U so that the side arms approach each other and grip the fixed block. Specification 501,815 is referred to. The Provisional Specification refers also to Specification 547,327, [Group XXXVII].
