Abstract

570,634. Electromagnetic interrupters. RUSSELL, E. S. Oct. 21, 1943, No. 17371. [Class 38 (v)] An electromagnetic interrupter with adjustable time lag comprises a solenoid 1 which attracts a hollow core 2 upwards thereby stressing a spring 4 between the core and a rod 3 connected to a time lag device, (not shown), so that the rod 3 follows the core 2 slowly upwards and at a predetermined time an adjustable projection 8 actuates a tilting mercury or other switch which breaks the solenoid circuit and also controls other circuits. The core 2 then falls by gravity carrying the rod 3 with it and at a time determined by a second adjustable projection 14 returns the switch to its original position, the cycle then recommencing.
