ABSTRACT:
An electric iron is provided with an orientation-detecting switch and a timing circuit, which, after the iron is unmoved in the horizontal or vertical positions for preset times, respectively, activates a heating resistor in the iron to trigger a manually resettable thermostatic cutoff switch. The iron also includes a temperature-sensing resistor and a potentiometer in circuit with a comparator and indicator means, whereby when the temperature reaches a level to which the potentiometer is set, the indicator means indicate that the iron is at ready temperature.
