Abstract

119,016. British Thomson - Houston Co., (General Electric Co.). June 1, 1918. Push-button systems; controllers with no-volt release.-The circuit of the motor 1 is closed by the contactor 3, the actuating-circuit of which is completed by the push-button switch 4 after the switch 5 has been closed. The switch 4 is held closed by an electro-magnet 8 which is energized through the contact 13 and acts as a no-volt release. An overload relay 10<1> controls a contact 9 in the retaining-circuit, and the starting resistance 2 is controlled by the series contactor 12. In a modification, the start-and-stop button switch 5 is replaced by a drum switch.
