Abstract

118,922. Brougham, F. J., (Saurer, A. [Firm of]). Oct. 12, 1917. Thermostats. - In apparatus for operating the damper 4 of a furnace 1 by a hightension motor 23 under the control of a thermo-electric element 5 in the furnace, the movable contact 16 of a switch placed in the motor circuit is operated by the low-tension current of the thermal element and is supported at a distance from the fixed contacts 17, 18, 19 being pressed down upon the fixed contacts at predetermined intervals by clock-work or other mechanism. The movable contact is rotated in the manner of a galvanometer needle by a coil 7 in the circuit of the thermal-element. An adjustable resistance 10 is provided in the circuit for regulating the operation of the switch. The movable contact is pressed down by a bridge-piece 30 on an axle 31 connected to the clock-work mechanism.
