Thermostat and iron assembly

Abstract

A stacked snap-acting thermostat assembly in which a modification is provided of a single structural bracket extending over all the blades and mounted on and above the supported end with an enlarged integral portion having a bore therethrough to form an elongated bearing guide and support a control shaft rotatably in the bore contacting the tension part of the first element to position the upper spring blade. An arcuate cam surface is provided with end stops and facing the upper blade and a cam follower on the control shaft is biased by the upper blade against the cam surface, the entire arrangement providing a snap-acting thermostat of compact size with an improved mounting arrangement whereby a single bracket stacked mounting performs multiple functions of a shaft bearing, cam surface and end stops and with its shaft acting as an adjustment on the first element tension portion to vary the snap-action of the thermostat and act as a fixed locator of all the structural parts in intimate contact with an iron soleplate.
