Abstract

470,615. Spark-preventing in switches. LEYHAUSEN, W. Feb. 15, 1937, No. 4433. Convention date, March 27, 1936. Addition to 470,521. Drawings to Specification. [Class 38 (v)] The invention described in the parent Specification is improved by dividing the spark-chamber into a plurality of compartments by partitions arranged parallel to the direction of contact-movement and to the arc gap. Preferably two partitions are arranged on each side of the chamber and are united by cross-members.
