Abstract
Abstract A CLAMPING AND INDEX SHAFT IS MOUNTED FOR RECTILINEAR RECIPROCAL MOVEMENT BETWEEN EXTENDED AND RETRACTED POSITIONS AND ALSO FOR ROTARY MOVEMENT BETWEEN INDEX POSITIONS. A TOOL BLOCK IS MOUNTED ON THE SHAFT FOR MOVEMENT THEREWITH BETWEEN INDEX POSITION, AND A COUPLING MEMBER IS MOUNTED ON THE SHAFT FOR MOVEMENT THEREWITH INTO AND OUT OF RETRACTED POSITION. ANOTHER COUPLING MEMBER ENGAGES THE ONE TO HOLD THE SHAFT AGAINST INDEXING WHEN THE SHAFT IS RETRACTED. A MOTOR IS OPERABLE TO MOVE THE SHAFT BETWEEN EXTENDED AND RETRACTED POSITIONS, AND ANOTHER MOTOR IS OPERABLE TO ROTATE THE SHAFT BY THE INDEX POSITIONS. THE ONE MOTOR IS ARRANGED IN CONTROLLING RELATION TO THE OTHER FOR INDEXING THE SHAFT ONLY UPON MOVEMENT OUT OF RETRACTED POSITION, THEREBY DISENGAGING THE COUPLING MEMBERS.
