Abstract

8140. Siemens Bros. & Co., [Siemens & Halske Aktiengesellschaft]. April 18. Motors, electromagnetic.-An apparatus for vibrating the axles A or bearings G of electric meters, to diminish friction, consists of a spring F carrying an armature B, which is acted on by an electromagnet C, supplied with current through a resistance W, and short-circuited periodically by a contact K on the spring. The armature B is solid, and may have copper pins set in it, or a shortcircuited winding placed on it, to delay its magnetization. The magnet C may have a laminated core. The magnet may be supplied with alternating current, and the contact K dispensed with.
