Abstract

A dual-purpose puncher combining two-hole and three-hole punch assemblies, is shown and described. The dual purpose puncher provides a duality of uses to the consumer without the necessity for readjustment. In the preferred embodiment, the two-hole punch assembly is positioned opposingly to the three-hole stationary punch assembly in such a way that a central arm of the press lever frame of the three-hole punch assembly passes between two arms of the press lever frame of the two-hole punch assembly. In another embodiment, the modified press lever frame of the three-hole punch assembly slidably engages the modified press lever frame of the two-hole punch assembly thereby driving both, the punch set of the two-hole punch assembly and the punch set of the three-hole punch assembly. Either embodiment combines both punch assemblies and a platform into a single unit while reducing the platform's footprint.
