Abstract

212,217. American Radiator Co., (Assignees of Eggleston, L. W.). Feb. 27, 1923, [Convention date]. Thermostats. - The supply of air through a passage 19 to the ash-pit of a sectional boiler furnace is regulated by a damper 42 controlled by a thermostat arranged in a recess 25 formed in the rear section 12 of the boiler. The thermostat comprises an outer casing 26 and an inner metallic bellows 27 enclosing a space containing alcohol, ether or other volatile fluid. The outer ends of the casing and bellows are connected by a flange serving to seal the s p a c e between them. The inner end of the bellows is connected to a plunger 33, which is also connected to a lever 40 pivoted at 41 and carrying the damper 42. When the bellows expands due to rise in temperature in the boiler the plunger 33 operates the lever 40 to close the damper. The damper is closed against the resistance of a spring 58 attached to the lever and to a plate 56 engaging with a helical groove in the shaft 51. By turning the shaft 51 the position of the spring and the resistance against which the damper is closed may be varied. By removing the casing 26 of the thermostat and exposing the bellows 27 the damper may be controlled by steam pressure.
