Title: Coupler for electric furnace electrodes

Abstract: An electric furnace electrode coupler comprises a power driven chain loop which wraps tightly around a new electrode section such that when the belt is translated the new section is turned and screwed onto an operating old electrode section. Means are provided for tensioning the chain for gripping. The drive mechanism for the chain is mounted on an extensible and swingable arm for enabling operation on several electrodes associated with one furnace.
