Abstract
An analog thermometer of the bimetal coil type has a rotatable hub carrying the bimetal coil. The thermometer is calibrated to indicate exact ambient temperature by rotating the hub to the proper angular position. The hub and the base supporting the hub are designed to allow fabrication as a unitary molded plastic article. A preferred embodiment of this design comprises at least four inwardly projecting tabs carried in an opening in the base and spaced from each other around the periphery of the hole. The hub has at least four outwardly projecting tabs spaced about its periphery. The angles which each of the hub's tabs and the hole's tabs subtend and the tabs' axial positions allow the hub to be rotated to interleave the tabs, restraining the hub in a predetermined axial position and frictionally fixing the hub in the angular position for calibration.
