  • Patent number: 5427299
    Abstract: A manually powered fastening tool that stores and instantly releases the energy of a spring such that it forces a staple or other fastener into an object by an impact blow, wherein the operating handle is hinged near the end of the tool body opposite the end from which the staples exit. A staple ejecting plunger is unstably linked to spring actuating levers such that with the removal of a light holding force, the plunger and actuating levers are de-linked. The tool housing comprises a cantilevered rear profile.

  • Patent number: 5328075
    Abstract: A manually powered fastening tool which stores and instantly releases the energy of a spring such that it may force a staple type fastener into an object by an impact blow. In the present invention the squeeze handle is hinged near the end of the tool body opposite the end from which the staples exit. The user grips the tool near the staple exit end and pushes the squeeze handle toward the intended staple impact point. This novel arrangement causes the user to force the staple into the receiving object with the same hand that pushes the squeeze handle toward the tool body, while the prior art typically requires use of a second hand to hold the tool firmly upon the staple impact point. Improving from the prior art, the present design ensures that the staple exit end of the tool body will not lift away from the receiving object. The energy storage spring and handle engagement linkage are located remotely from the plunger in the present design.
