Abstract
303,040. British Thomson-Houston Co., Ltd., and Hastings, H. C. Sept. 26, 1927. Addition to 233,438. Master control, electromagnetic. -Relays 104, 105 which when energized alternately by a voluntary action, e.g. by the driver of a train, carry on successive closure of a set of electromgnetic contractors for accelerating a motor M independently of a two-wire current-limit notching device P, P<1> are connected to additional mastercontroller fingers e<1>, f<1> instead of the separate two-way switch described in the parent Specification. The object is to permit the driver to effect non-automatic notching by to-and-fro movement of the master-controller.
