ABSTRACT:
This invention relates to a thermostat mounting arrangement suitable for use in a clothes dryer. Thermostat mounting arrangement includes a thermostat mounted to engage the inner and outer opposing sides of a surface supporting portion of the clothes dryer to sense temperature conditions in the clothes dryer. The mounting arrangement is characterized by an aperture passing through the surface supporting portion. The aperture has an enlarged central opening with four projection tab members extending into the central opening and two diametrically opposed slots extending radially outward from the central opening. The thermostat includes a temperature sensitive flat surface adapted for positioning within the central opening of the aperture slightly beyond the inner surface of the surface supporting portion of the clothes dryer. The thermostat has two resilient wings each having an arm extending generally toward and through a corresponding slot of the aperture. Each arm terminates in a bent end member adapted to engage the inner side of the surface portion adjacent the slot of the aperture. The thermostat has a depressed shoulder surrounding the temperature sensitive flat surface which engages the outer side of the projection tab members extending into the central opening of the aperture.
