  • Patent number: 6179193
    Abstract: An impelling blade guide is inserted into a space provided for inserting a blade unit in order to create a simple structure for the removal of staples which have become jammed in the staple ejecting mouth during empty operation. A notched section is formed in proximity to the staple ejecting mouth of the frame. During normal operation, the impelling blade guide can be easily raised since an indentation formed on the notched section and a projection formed on the impelling blade guide are fixed. When a staple is jammed in the staple ejecting mouth, the impelling blade guide is pulled up and the projection separates from the indentation. Thus the rear surface side of the staple ejecting mouth is opened. In such a way, jammed staples can be easily removed from the staple ejecting mouth.

  • Patent number: 5511715
    Abstract: A power tool has a flywheel for driving a working member such as the driver of a fastener tool. A motor mounted at a rear end of a tool handle drives the flywheel mounted in a tool housing at the forward end of the handle. A cable is secured to a drum and to the working member. A clutch selectively couples the flywheel to the drum to wind up the cable and drive the working member forcefully. A return cable is wound on the driver drum against a spring bias to rewind the drum, unwind the cable and return the working member to its prior status when the clutch decouples the flywheel from the drum. When coupled to the drum, the motor speed and flywheel speed is reduced. An electronic control operates the motor to recapture the initial speed within 500 milliseconds of the speed reduction. The electronic control includes a phase-locked loop velocity control.

  • Patent number: 5460314
    Abstract: A stapler having improved stapling precision is provided. In a preferred embodiment, a stapler has a magazine with a staple driving unit, and a staple clinching unit wherein the magazine and the staple clinching unit are separately disposed. The magazine of the stapler is provided with a actuation linkage and guides which cause the magazine having the staple driving unit to consistently move in a substantially vertical direction with respect to the staple clinching unit, so that a staple driven thereby is driven in a direction substantially perpendicular to sheets of paper to be stapled, regardless of the thickness of the paper. In a variant of the preferred embodiment, the stapler is incorporated in another unit where the stapler is moved from one operating position to another. In order to maintain the alignment of the separately disposed magazine and staple clinching unit, alignment members are provided on either a frame supporting the magazine or a frame supporting the clinching unit, or on both.
