Abstract

An improved spring-energized stapling machine comprises a body, an actuating arm which is secured to the body to pivot about a pin, a movable fitting and a driving pin extending through an end portion of a tongue on the arcuate arm and through arcuate slots in the body. When the actuating arm is in its original position, the driving pin will be at the lower end of the arcuate slots and contacts the fitting so as to move the fitting away from a base of the body.
