  • Patent number: 4653708
    Abstract: A thermostat mounting arrangement includes a thermostat fixedly retained by a mounting member, and the mounting member then being mounted in a panel using a "twist-in" motion. The mounting member is of one-piece metal construction having a tubular housing portion, a pair of rigid arcuate flanges at its base and, intermediate the arcuate flanges, a pair of separate resilient flange tabs. The flange tabs are spaced above the rigid arcuate flanges and include downwardly-extending detent knobs. The panel includes a notched aperture for passing the mounting member housing and the flange tabs in a certain rotative position. The flange tabs are inclined to facilitate both the rotation of the mounting member relative to the panel and its retention in the panel. The mounting member is rotated until the detent knobs on the flange tabs detentingly snap into detent holes in the panel.

  • Patent number: 4533894
    Abstract: An adjustable bimetal snap disc thermostat is disclosed which provides conventional resistance-type heaters symmetrically positioned adjacent one side of the snap disc to allow adjustment of the operating temperature of the thermostat. The heaters are supported by heater terminals which extend up through the thermostat body and cover, and connect the cover to the thermostat body. The heaters and heater terminals are connected as a subassembly and subsequently installed as a unit in a device to minimize assembly costs. Further, since the heaters are conventional commercially available heaters, the cost of the heaters per se is minimized.
