ABSTRACT:
A single punch head is slidable along a multi-faced, rotatable, horizontal bar having different arrays of detents on its several faces; a spring-pressed ball coacting successively with the detents on any selected face of the bar to position the head for punching holes spaced correspondingly to the detent spacing on the selected face. The ball also serves to hold the bar somewhat yieldably in any of the plural face positions to which the bar may be turned.
