Abstract

See full text

A resilient anvil for clinching staples driven through a drive track is adjustably mounted on the stapler to permit compensation for wear and to otherwise control the curl or clinch applied to the driven staple. Overlapping or partially aligned openings in the anvil and a fixed adjusting or locating plate provide camming edges or surfaces adapted to be engaged by, for example, an inserted screwdriver bit. When the bit is turned, the position of the anvil relative to the drive track is varied. Threaded fasteners lock the anvil and plate in the adjusted relative positions on the stapler.
