Stapling machine

Claim 1

A spring-energized stapling machine for both paper-fastening and staple-injecting comprising: a body including a base, an operating handle, and spring means for driving staples as a result of movement of said handle; a check plate having a tip end and two parallel sides, each of said sides having a slot therein, said check plate being slidably mounted on said body by way of a pin extending through said body and through said slots in said check plate such that said check plate is slidable to a position in which the tip end of said check plate engages said operating handle and thereby obstructs the movement of said operating handle; a movable fitting having an inverted U-shaped slot and two recesses included therein, said fitting mounting upon said body by way of two pins which also define two alignment points which said movable fitting is slidable thereabout whereby said fitting is slidable through a plurality of angularly and longitudinally displaced positions, said fitting forming a backing plate to clinch the ends of staples in said recesses as said staples are driven for paper-fastening when said fitting is in a first of said positions, said fitting forming a safety shield to preclude accidental driving of staples by blocking the path of staples driven by said spring means when said fitting is in a second of said positions, said fitting allowing the injecting of staples into objects when said fitting is in a third of said positions; a staple supply means possessing two sets of parallel grooves to accept staples of two different sizes, said supply means being positioned to supply staples to said spring means; and means for staple removal mounted on said base.
