BIMETAL LID LOCK ABSTRACT OF THE DISCLOSURE A safety interlock for a door of an automatic washing machine is disclosed. The interlock securely latches the door during a spin cycle to prevent the operator of the machine from opening the door and catch- ing his hand in the rotating motor driven drum. The inter- lock operates during operation of the motor and during a time delay period following de-energization of the motor to permit the drum to coast to a safe speed or to a stop. In- eluded in the interlock is a switch member operable upon closure of the door to at least partially complete a circuit between the motor and a bimetallic element. The remainder of the circuit is completed by a timer driven switch, and when the circuit is completed the bimetallic element is heated to move a latch on the frame of the appliance into locking engage- ment with a latch on the door.
