Abstract

106,029. Back, H. C. July 22, 1916. Electro-magnetic interrupters; contacts.-For adjusting the contact screw 2 of the armature 8 of a field telephone induction coil &c, the head of the screw is formed as a worm-wheel 3 for engagement with a worm 6 upon a shaft 4 mounted in bearings 5 on a solid plate or bracket 1 through which the screw passes. The shaft is rotated by means of its head 7.
