Abstract
267,243. Standard Telephones & Cables, Ltd., and Gowring, H. J. Dec. 15, 1925. Electromagnetic interrupters.-An electric bell or buzzer comprises two magnet coils 1, 2 the cores of which are provided at one end with a magnetic yoke 6 and at their other ends with adjustable inwardly - projecting polepieces 3, 4, between which a pivoted armature 5 mounted on the yoke 6 is arranged to vibrate and in so vibrating to direct the current alternately to the two magnet coils.
