Abstract
23,774. Graetzer, O. Oct. 28. Couplings. - An electric coupling comprises frictiongrip balls c mounted in chambers in a carrier b, which is guided in a conical casing a. The cover f which closes the end of this casing serves as the guide for the stem of the carrier. The wire d, inserted in a hole in the carrier, is gripped by the balls, which are wedged against the casing by the action of the spring e. The carrier is drawn up to liberate the wire by a key screwed into the end of the stem ; or, the stem may project and be provided with a knob of insulating-material. In a modification, the stem does not pass through the cover, but the carrier is formed with an extension to pass through the bottom of the casing. The device may be used for branch connexions, and it may be duplicated, as shown in Fig. 9, to form a coupling. The balls may be arranged to press the wire against one side of the carrier.
