DEFINITION

Classification: 314/38

(under subclass 36) Subject matter having two or more movable electrodes connected together by mechanical means so that these movable electrodes are each moved by the same motive power means.

(1) Note. In many of the patents in this subclass the two movable electrodes each cooperate with the same third electrode to establish the electrical discharge.

(2) Note. Continue the search in subclass 37 of this class.

SEE OR SEARCH THIS CLASS, SUBCLASS:

3, and 4 and indented subclasses, for consumable electrode discharge devices having three or more electrodes wherein the discharge is initiated between two of the electrodes and is maintained between these electrodes until at least one of the electrodes is consumed, the discharge then being shifted to another electrode or to other electrodes, and having two or more movable electrodes connected together by mechanical means so that these movable electrodes are operated by the same motive power means.

33, for consumable electrode devices having three or more electrodes connected in series relation in the circuit, and having two or more movable electrodes connected together by mechanical means so that these movable electrodes are operated by the same motive power means.

53, and indented subclasses, for miscellaneous consumable electrode discharge devices having the electrodes connected together by mechanical means so that the electrodes are each fed towards the other by the same motive power means during the feeding operation.
