ENSEMBLE DE THERMOSTAT ET DE FER A REPASSER

THERMOSTAT NECESSITANT UN PETIT NOMBRE DE PIECES.IL COMPORTE UN EMPILAGE CONSTITUE PAR UN BILAME INFERIEUR 48, UNE LAME INTERMEDIAIRE RIGIDE CONDUCTRICE 50, UNE LAME SUPERIEURE CONDUCTRICE SOUPLE 52 ET UN ORGANE SUPPORT 54 SOLIDARISES, A UNE EXTREMITE, AVEC INTERPOSITION DE RONDELLES ISOLANTES 58, PAR UN RIVET 60. UN ORGANE 66 PORTE PAR LE BILAME EST UN APPUI CONTRE LA LAME SUPERIEURE POUR LA PLACER DANS UNE POSITION CORRESPONDANT A LA TEMPERATURE DETECTEE TANDIS QUE L'ORGANE SUPPORT COMPORTE UNE EXTREMITE LIBRE ELARGIE 76 DANS LAQUELLE EST MONTE A ROTATION ET A COULISSEMENT UN ARBRE DE COMMANDE 74 DONT L'EXTREMITE 70 EST UN APPUI CONTRE LA LAME INTERMEDIAIRE. LE DESSOUS DE L'EXTREMITE ELARGIE 76 FORME UNE SURFACE DE CAME 82 QUI COOPERE AVEC UN ERGOT 86 PORTE PAR L'ARBRE DE COMMANDE AFIN DE REGLER LA TEMPERATURE EN FONCTION DE LA POSITION ANGULAIRE DE L'ARBRE.APPLICATION A UN THERMOSTAT DE FER A REPASSER. 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.
