6HW-5311 THERMOSTAT AND IRON ASSEMBLY ABSTRACT OF THE DISCLOSURE A stacked thermostat assembly includes a lower heat deformable blade, a conductive intermediate stiff spring blade, and a conductive upper less stiff spring blade with all the blades being supported, secured, and spaced apart at one end by interposed insulator. Electrical contacts on the conductive blades include structure for transmitting movement between the heat deformable blade to the upper blade to make and break an electric circuit and control heat to a medium sensed by the thermostat such as an iron soleplate on which the thermostat may be mounted. To this standard construction an improvement is provided in the temperature setting control mechanism of 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 acurate 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°-210° 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.
