MEJORAS A ENSAMBLE DE TERMOSTATO EN UNA PLANCHA DE VAPOR

To a standard stacked thermostat assembly construction as used in an iron an improvement is provided in the temperature setting control mechanism of a single structural integral bracket extending over the blades and mounted on and above the supported end, the bracket having an enlarged integral portion on its free end. A smooth unobstructed bore in the integral portion forms an elongated bearing guide between the ends of and over the blades. In the bore a control shaft is rotatably supported and extends through an opening in the upper blade to position the intermediate blade and set temperature. An arcuate cam surface with end stops is formed directly on the integral portion facing the upper blade and a cam follower is provided on the control shaft and biased by the intermediate blade against the cam surface which extends over an arc of substantially 180 DEG -210 DEG and has a short arc angular rise at one end adjacent a stop. The structural arrangement allows a single integral bracket to perform multiple functions of a shaft bearing, a cam surface with its included stops, and a single locator of all the structural parts of the stacked thermostat assembly for installation as a package on an iron soleplate.
