Abstract

524,868. Reciprocating motors WESTING- HOUSE BRAKE & SIGNAL CO., Ltd., and WALKER, A. H. B. Feb. 7, 1939, Nos. 4000 and 20027. [Class 35] The coil 1 of a vibrating electric motor operating, for example, a screen or tool, is supplied from an alternating current source RS and a source of direct current, is connected across a condenser or secondary battery, connected between the coil and the source RS. The source of direct-current may comprise a rectifier bridge 6 connected across a condenser 2, and supplied from a transformer 4 with variable tappings 7, 8, 9. Alternatively the vibrator coil 1 may be used as an autotransformer or provided with a secondary coil for supplying the rectifier. A resistance may be provided for adjusting the direct-current.
