  • Patent number: 9943952
    Abstract: An electro-pneumatic tool drives a fastener into a workpiece by energizing an electric motor to drive a first piston and generate compressed air in a first cylinder. The compressed air is then supplied to a second cylinder and causes a second piston to move and drive the fastener into the workpiece. After the first piston has passed through its top dead center, braking is applied to the first piston according to one or more braking parameters. Then, if a control unit determines that the first piston has come to a stop at a position that is outside a predetermined range about the bottom dead center of the first piston, one or more of the braking parameters is changed in a subsequent fastener driving cycle to cause the first piston to stop closer to its bottom dead center after conclusion of the subsequent fastener driving cycle.

  • Patent number: 6991146
    Abstract: A stapler having a detached base supporting an anvil and a first magnetic element, and a stapling assembly for ejecting staples from a magazine port. The stapling assembly supports a second magnetic element positioned for magnetic coupling to the base to align the anvil with the magazine port. Accordingly, the staple-driving stapling assembly and detached anvil-supporting base are not mechanically coupled. Instead, the stapling assembly and base are magnetically couplable. The magnetic coupling feature eliminates throat depth limitations and allows for staple placement at any desired location on a sheet of any size. An alignment guide may be provided to visually indicate an approximate location where a driven staple will be placed. The base and stapling assembly may be provided with friction pads for limiting movement of any sheets therebetween while stapling.

  • Patent number: 6955282
    Abstract: A magnetically operated driving tool includes a body member, first and second stator magnets at opposed ends of the body with like poles facing one another, a movable magnet (traveler), a coupling adjacent each stator coupled to a user-operable linkage, a hammer, and a spring. In use, the traveler begins magnetically coupled to the first stator and engaged with the first coupling; the hammer holds a fastener. A user operates the linkage, rotating the traveler until its and the first stator's polarity match. The first stator magnetically repulses the traveler, which propels the hammer to insert the fastener and moves to the second stator where it engages the second coupling. The user operates the linkage, causing the traveler to rotate until its and the second stator's polarity match. The second stator then magnetically repulses the traveler, which engages the spring and reaches the first stator, returning to the initial configuration.

  • Patent number: 6805272
    Abstract: A pneumatic nail driver includes a main body having a cavity defined for receiving a spring and a sleeve that has an annular groove defined in an outer periphery of the sleeve. A passage is defined in the main body and selectively communicates with the annular groove for allowing the compressed air flow into the sleeve. A block and a cylinder are sequentially received in the cavity. A striker is reciprocally movably received in the cylinder due to the block and the compressed air. A shaft partially longitudinally extends into the cylinder and the striker is moved to strike the shaft for driving the nail when the shaft and the cylinder are backward pushed to make the annular groove communicate the passage to guide the compressed air flowing to the cylinder for pushing the striker.

  • Publication number: 20040173658
    Abstract: A device attaches to a roofing nail gun for individually feeding disc-shaped tin tags into centered alignment with the nail gun hammer for safe and accurate center nailing of the tin tag to a host surface. A chute on the device extends from an open top end to a bottom end having a tin tag passage hole centered below the nail gun hammer. Tin Tags are individually deposited through the open top of the device and slide down the chute. Magnets at the bottom end direct and hold the tin tag in centered alignment between the nail gun hammer and passage hole. The bottom portion of the chute is spring biased to allow the nail gun to be pressed downwardly so that the hammer urges the tin tag through the hole and against the host surface prior to firing the nail.
