13,724. Mavor, H. A., and Mavor & Coulson. June 13. Distributing.-An electric device for transmitting power, with a variable speed control, particularly suitable for propelling ships and road and other vehicles, is arranged by coupling the shaft g to be driven to an element e common to a polyphase generator a and a polyphase induction motor i, so that the shaft can be subjected to the reaction torque of the generator, augmented, diminished, or unaffected by the torque of the motor. The generator current, controlled by a variable resistance or by varying the field excitation of the generator, feeds the motor, and reversal is effected by reversing the current energizing the motor stator. The position of the motor elements may be interchanged. Specification No. 9950, A.D. 1907, is referred to.
