ABSTRACT:
An interlock device for the door of an appliance, such as a washing machine, to prevent operator access to the spin dryer drum while it is driven or coasting. The device comprises a switch and a bimetal element for being connected in a series circuit including a timer operated switch and the drum drive motor. A slotted latch member projecting from the door closes the switch when the door is closed and the motor becomes energized if the timer switch is closed. The bimetal is heated by motor current and causes a latch lever to engage and maintain engagement with the latch member until expiration of a delay period which exceeds the time required for the motor to coast to a stop.
