Abstract
An indicator device for proving an announcement of the status of a burner control knob, A base plate attaches to and rotates with a burner control shaft on a stove. An attitude sensing switch mounted with the base plate changes its conductive state when a burner control shaft moves from an “off” position. An annunciator senses the change in conductive state to initiate an announcement of that event.
Claims19
An indicating device that provides an annunciation of rotation of a burner control shaft in a stove from an off position to any of a range of angularly displaced positions, said indicating device comprising:
- A) reference means mounted on the stove for defining the off position;
- and
- B) a control system for indicating an angular displacement of the control shaft from the off position including:
- i) a base attached to the control shaft for rotation therewith,
- ii) electrically-operated annunciator means mounted on said base,
- iii) a battery operated power supply mounted on said base, and
- iv) switching means mounted on said base and connected between said power supply and said annunciator for establishing an open circuit when the control shaft is at the off position whereby said annunciator is inactive and for activating said annunciator means when the control shaft is displaced from the off position.
A burner alert control for annunciating rotation of a burner control shaft in a stove from an off position to any of a range of angularly displaced positions, said burner alert device comprising:
- A) a magnet mounted on a stove proximate the burner control shaft at a position corresponding to an off position of the burner control shaft, and
- B) a control system for indicating an angular displacement of the burner control shaft from the off position including:
- i) a base attached to the burner control shaft for rotation therewith,
- ii) electrically-operated annunciator means having at least a portion thereof mounted on said base,
- iii) a battery operated power supply mounted on said base,
- iv) switching means mounted on said base whereby said magnet and said switching means portion on said base are aligned when the burner control shaft is in its off position, said switching means establishing an open circuit when the burner control shaft is at the off position whereby said annunciator is inactive and a closed circuit for activating said annunciator means when the burner control shaft is displaced from the off position.
