Abstract

348,151. Heating water by electricity. CHALMERS, A., 249, William Street, Anderston, Glasgow. Feb. 8, 1930, No. 4296. [Class 39 (iii).l A float 9 in the boiler 1 is operatively connected to a switch 4 included in the circuit of a contactor C adapted to break the heating circuit when the water is below a certain level and to make the circuit when the level is restored. The switch 4 is provided with a sliding push button 5 embraced by a rectangular ring 6 connected by screws 7 to the float rod 8. The switch is housed in a watertight casing 10. The rod 8 is a tube forming a vent for the float.
