Abstract
146,665. Tavener, J. April 30, 1919. Motor meters.-The circuit through the shunt coil of an integrating watt-meter is closed only when one or more consuming devices such as lamps are switched on. As shown, the supply to a house is taken through a coil F of a thermal switch consisting of a balanced tube containing mercury D. When a lamp L is turned on the mercury is displaced and the circuit through the shunt coil SC closed at the contacts H. To prevent over rapid movement a second coil F<1> is used of less effect than the coil F but opposed thereto; or a resistance in shunt to the coil F may be used. In place of the thermal switch an electromagnetic switch may be used.
