Abstract
A window thermometer of the bimetallic type has a circular casing with a dial plate received in the casing for rotation relative thereto. The bimetallic element has one end coupled to the casing and the other end to a dial pointer. Suction cups with stems are secured to the dial plate by fasteners that pass through the casing and plate, the fasteners holding the parts together and yet permitting temperature calibration by permitting the plate to rotate relative to the casing when the fasteners are loosened.
