A New or Improved Method of and Apparatus for the Control of Electric Supply Plant.

Abstract

135,922. Read, H. J., and Bransom, W. J. Dec. 2, 1918. Systems of charging galvanic batteries.-In a supply plant consisting of a prime-mover, generator, and battery, the charging of which is under the control of an electrolytic meter, the meter controls the ignition circuit and throttle valve of the engine and an engine turning-gear so that the generation is automatically started and stopped according to the condition of the battery. One electrode f of the meter is balanced by a spring k and, according to its weight, either opens or closes the ignition circuit &c. In a modification, the variation in weight of both electrodes is used to energize two oppositely-acting solenoids alternately and throw over a switch for the same purpose. The action of the electrode may be direct or through relays on the switch. The relay devices and frames described in Specification 22348/13 mav be used with the electrolytic meter. The switching-devices may cause the engine to start on petrol and run on paraffin.
