Abstract
1,222,550. Machinery safety devices. INDUSTRIE A. ZANUSSI S.p.A. 17 May, 1968 [20 May, 1967], No. 23693/68. Heading F2J. The door latch 16 of a laundry or dish washing machine is mechanically actuated by a cam 24 on the shaft 25 of the machine programming unit 26 so that the door 11 cannot be opened until a predetermined time after machine operation has ceased. An arm 17 having a fixed pivot 18 carries the latch 16 and a U-shaped branch 22 on which is a follower 23 for the cam 24. A spring 20 holds the follower against the cam surface. During machine operation a circular portion of the cam allows the spring 20 to hold the latch 16 in engagement with a recess 15 in the door 11. The cam portion 29 acts when operation has ceased to withdraw the latch from the recess 15. An optical signal may be provided to indicate when the door may be opened, and a known safety circuit preventing operation of the machine if the door is is not properly closed can be included.
