DEFINITION

Classification: 314/16

(under subclass 15) Subject matter having the feed regulating mechanism operated by the electro-responsive means, such as an electromagnet, and having the shunt circuit switch actuated by the movement of the feed regulating mechanism.

(1) Note. Continue the search in subclasses 12 and 14 of this class.

(2) Note. In most of the devices in this subclass, the feed regulating mechanism is given an abnormal movement when the electrodes are either consumed or fail to feed, and this abnormal movement is utilized to operate the shunt circuit switch.
