ABSTRACT OF THE DISCLOSURE The specification discloses a forming die movable along a track by a pair of toggle-joint linkages to move from a column of staples a staple hav- ing a downwardly bowed central portion into engagement with an anvil, then bend outer portions down over the anvil to drive pointed legs into the flesh and bring the legs into alignment with each other. The column of staples is pressed by a spring arm and a follower toward the track and is laterally sup- ported in a staple magazine. Each toggle joint-linkage is a one-piece member with two rigid arms connected by an undulating spring portion. The magazine is detachably connected to the track by spring latches. Another stapler has a hook-like anvil, and the bowed central portion of the staple as it is pres- sed against the anvil by a forming die or ram, is first straightened and then bent legs are bent from the central portion, thus giving a "soft" initial feel to the stapling.
