Patent number: 4152578Abstract: The novel electric heating element is particularly useful as a water heating element, although its use is not so limited. The element comprises the usual metal-sheathed heater having electrical termination at one end of the sheath. The customary water heating element has a sheath of hair-pin formation, with the ends of the two legs of the sheath connected to structure which serves as a mounting member and an electrical connector. Such structure in the present application is of molded plastic with a metal insert.Type: GrantFiled: October 3, 1977Date of Patent: May 1, 1979Assignee: Emerson Electric Co.Inventor: David F. Jacobs

Patent number: 4136437Abstract: A method of mounting a potentiometer (pot) on a plate, wherein a hollow cylindrical housing appendage of the pot is positioned through a hole in the plate to the other side thereof. The rotatable shaft of the pot then projects to the said other plate side through the appendage. A washer, a jam nut and a seal nut are positioned around the appendage. A compound is then potted in contact with and around the pot housing sealing it to the plate, and around the shaft. The housing on its side of the plate is larger than the hole. However, the shaft is not primed and is therefore rotatable after potting. The plate is primed on both sides prior to potting.Type: GrantFiled: September 28, 1977Date of Patent: January 30, 1979Assignee: International Telephone and Telegraph CorporationInventor: Lowell J. Leyrer

Patent number: 4001547Abstract: Our invention relates to electric heating elements for heating liquid within a tank, and particularly to heating elements for use in domestic commercial water tanks, wherein the element comprises a metal mounting member secured to the wall of the tank and a sheath portion carried by the mounting member and extending through a hole in the tank wall for immersion in the water in the tank. The sheath portion contains a resistance conductor and insulation which electrically insulates the conductor from the sheath, so that water in the tank is heated when the resistance conductor is electrically connected to a source of electrical energy.Our invention provides means for protecting the electric heating element from damage which may otherwise be caused by a sudden surge of high voltage, such as that which may be caused by lightning disturbances in the immediate vicinity.Type: GrantFiled: December 22, 1975Date of Patent: January 4, 1977Assignee: Emerson Electric Co.Inventors: Alben C. Boggs, Robert D. Shirey

Patent number: 3997760Abstract: An electric resistance heating element for use in appliances such as dishwashers includes a mounting grommet having a resilient body portion sized to be forcibly urged through an aperture formed in a bulkhead of the appliance. A neck portion formed integral with the resilient body portion has an axial extent substantially equal to the thickness of the bulkhead receiving the grommet and a width to substantially fill the aperture. A head portion formed integral with the neck portion overlies the aperture on the side opposite that of the resilient body portion. A passage is formed axially through the body portion, neck portion and head portion to receive the end of a heating element therethrough. A flared tubular ferrule or conical tubular ferrule is provided at the end of the body portion to receive sealing cement for permanently securing the mounting grommet to the heating element inserted therethrough.Type: GrantFiled: December 6, 1974Date of Patent: December 14, 1976Assignee: Electro-Therm, Inc.Inventor: Fred G. Salinger

Patent number: 3934116Abstract: The heater assembly comprises a sheathed electric heating element and an elastomeric bushing within a sheath end opening. A mounting flange is rigidly secured to the sheath inwardly of an end, and the bushing is held under longitudinal compression at the time the mounting flange is secured to the sheath.Type: GrantFiled: October 23, 1974Date of Patent: January 20, 1976Assignee: Emerson Electric Co.Inventors: Donald M. Cunningham, Ralph Santoro
