ABSTRACT:
Single revolution clutch mechanisms are conventionally employed in machines such as punch presses and the like. Such clutches are usually provided with single stroke mechanisms so that an operator must release the "RUN" buttons before a subsequent cycle can be initiated. The present invention shows apparatus which prevents the initiation of a subsequent cycle of operation whenever the single stroke mechanism comes into operation. A latch is released upon such operation of the single stroke mechanism which prevents operation of the cycle-initiating means by the operator and requires the services of a maintenance man at the clutch mechanism to restore the clutch-iniatiating and single stroke mechanism to operating condition.
