Abstract:

An automatic-cutoff electric iron employs two timing cycles for turning off power to the electric iron upon the absence of motion for two different discrete time periods. A motion sensor includes an angle sensor to enable a short timing cycle for cutting off power to the electric iron after the electric iron is motionless with its sole plate in a horizontal orientation. The longer timing cycle is enabled when the electric iron is motionless with its sole plate tilted from the horizontal. The cutoff function is performed by a wedge-shaped actuator driven by a solenoid which releases a spring-urged shaft along with one of the electrical contacts feeding power to the electric iron. The power is turned on by mechanical actuation of the shaft whereby a latch member is engaged behind a cam boss. A manual cutoff is also disclosed.
