  • Patent number: 9718170
    Abstract: Sockets, for example, hexagon sockets, dodecagonal sockets, and splined sockets, that have inner surface geometries adapted to engage a flank of a fastener at a point away from a corner of the fastener. In general, the sockets engage the flank of the fastener at a distance of about 30 to 60 percent of half a length of the flank away from the corner of the fastener. This increases the strength and life of the socket, reduces a risk of the fastener becoming locked or stuck in the socket, and reduces the risk of the fastener being stripped or the socket slipping on the fastener.

    Abstract: A Framing Rafter Square Attachment. The attachment cooperates with a conventional rafter or framing square to make the repetitive cutting of lengths of framing lumber (such as for blocking) much easier and faster to accomplish. The attachment allows the position of the framing square as held by the attachment to be adjustable so that it can accommodate a wide variety of circular saw fence configuration. The attachment is extendable and retractable so that the attachment has both a compact size for storage, while at the same time being able to accommodate longer cuts. A drag clip may be provided to allow the user to selectively pinch a piece of wood with the attachment so that the pinched piece of wood can then be repositioned for another cut without the user having to set down either the circular saw or the attachment. Finally, the attachment has a subassembly that allows the user to easily cut a piece of lumber to fit a preexisting length or opening.

  • Patent number: 7162809
    Abstract: The invention is directed to a guide for a power saw or router of the type having a blade and a housing wider than the blade which directly overlies the blade during the cutting operation. The guide includes a guide bar having a straight outer edge configured for guiding a peripheral edge of the saw housing and a gauge device. The gauge device includes an elongated holder and a light beam projector mounted on the holder for projecting a beam of light at an angle relative to a lengthwise axis of the holder. In this respect, the light beam projector is mounted on the holder for projecting a beam of light at a right angle relative to a lengthwise axis of the holder such that the beam of light is parallel to the straight outer edge of the guide bar. The light beam projector is preferably a laser.

  • Patent number: 7086173
    Abstract: A positioning member (21) of a calibration tool (20) touches a slitting edge (17) of one of the blades (11, 12) to be calibrated of a slitter-winder of a paper or board machine. The tool (20) position is measured by the multipoint measurement method and edge position is determined based on the measurement result of the position of the calibration tool (20). A device for calibrating blade position is disposed in connection with the slitter-winder which comprises a top blade (12) and a bottom blade (11), attached to respective blade carriages (11A,12A) which are movable along a guide (14,13). The calibration tool (20) is arranged to be attached to the same guide (14) with the blade (11) to be calibrated. The calibration tool (20) has a means (21) for indicating the slitting edge (17) of the blade (11) and means (23,16) for measuring the position of the calibration tool (20).

  • Patent number: 6757984
    Abstract: A novel guide is disclosed for fixing to a cutting tool for cutting a piece of sheet material having a plurality of fiducial lines marked thereon. The guide has a set of alignment marks and a plurality of measurement scales associated with the alignment marks. Each measurement scale corresponds to at least one of the fiducial lines, such that when one of the alignment marks is aligned with a particular fiducial line, the measurement scale corresponding to the particular fiducial line indicates the distance of the blade of the cutting tool from an edge of the sheet material. Particular embodiments of the guide include a flat portion attached to the front of the cutting tool, or alternately, a laser guide rotatably fixed to the front of the cutting tool. Novel methods for cutting a predetermined distance from an edge of a piece of sheet material using the guides of the present invention is also disclosed.
