ABSTRACT:
A latch mechanism in one position causes a ram and the punch mounted thereon to be forcefully actuated in unison with the pivotal arm constituting part of the drive means. In a second position of the latch mechanism, the ram, together with the punch, can be manually lowered without being powered so that an alignment of the die with the punch can be achieved before performing a powered punching operation.
