Abstract
A staple forming and driving tool (10) employing a vertical front portion of a staple head base (34), and sheath (40) to provide a space for the reciprocating former member (70) and a driver (80). A spring (50) urges base (34) and the sheath (40) together with spacer lugs (33) maintaining a defined distance between the base (34) and the sheath (40). A belt of staple blanks is fed through an opening (100) in the base (34) by a cartridge. The cartridge extends into the opening (100). A belt advancing means (104, 112) is provided which is held in an inoperative position by the forming tang (75) during a portion of the forming and driving stroke in order to prevent movement of a staple wire (200) during critical portions of the forming and driving stroke. The former (70) is moved during the forming and driving stroke through a path which permits former lugs (72) to guide the formed staple down to a point adjacent the workpiece.
