(under subclass 99) Subject matter having the retarder connected to the electrode holder so as to control the rate of feeding throughout the feeding movement of the electrode.
(1) Note. In most of the patents in this subclass during the feeding operation the electrode is released from engagement with the electrode operating mechanism, the electrode falling under the influence of gravity, with the rate of falling being determined by the retarder.
(2) Note. Continue the search in this class, subclass 82, for consumable electrode discharge devices wherein the rate of motion of the feeding electrode while feeding is regulated by an escapement.
(3) Note. Continue the search in this class, subclass 68 and
indented subclasses, particularly subclass 70, for consumable electrode discharge devices provided with positive acting electrode feeding mechanisms and means for controlling the rate of feed of the positively fed electrode.
