ABSTRACT:
A safety device for use with machines in which the operator must use his hand or hands to position a work piece in the vicinity of a subsequently descending potentially dangerous element. The mechanism includes a downwardly movable probe which if intercepted by the operator's hand will prevent the machine element from operating. Removal of the hand to a safe position enables the probe to fall and the machine operation to proceed. The mechanisms are controlled by air actuated valves which automatically direct compressed air sequentially to the operative elements.
