Abstract

9502. Nicholson, A. H. April 22. Electro-magnetic interrupters of the vibrating-contact type are provided with a stationary contact a which is automatically kept in adjustment, relatively to the vibratory contact spring h, by a spring f of less power which urges the contact a against the spring h while the parts are at rest. The spring f, however, is prevented from doing so, while the apparatus is working, by a locking-bar d attracted by an electro-magnet in shunt to the working circuit so as to jam the slidable contact rod b against its bearing c. In a modification, the contact rod b is provided with an armature held by an electro-magnet. In a further modification, the contact rod is locked by a mechanical connexion, such as a spring, to the main circuit-closing switch.
