  • Automatic shut-off and alarm for electric heater
    Patent number: 5007103
    Abstract: An electric heater assembly which provides an alarm warning when an abnormal condition occurs and which simultaneously disables the electrical heating elements is provided. The heater element assembly includes a heating element, an electrically actuated alarm which provides an alarm warning when an abnormal condition occurs, and a tip-over switch which provides a closed circuit when the heater is in a predetermined level position and which provides an open circuit when the heater is tilted beyond a selected tilt angle. The electrical heating element, electrically actuated alarm, and tip-over switch are electrically connected such that the tip-over switch disables the heating element and actuates the alarm when the tip-over switch is in one of the open and closed positions, and such that the tip-over switch enables the heating element and disables the alarm when the tip-over switch is in the other of the open closed positions.
