  • Patent number: 9375860
    Abstract: Adjustable guidebushes and methods for using the same facilitate cutting joint elements into work-pieces to join together two or more of the work-pieces. In some embodiments, the adjustable guidebush includes a guide surface defining a number of outer diameters having different lengths. Positioning different outer diameters of the guide surface to interact with a cutting guide allows one to adjust the fit of the joint elements formed in the work-pieces.

  • Patent number: 6736173
    Abstract: A guidebushing assembly for use with an electric router. A guidebushing holder clamps to the router base, and a guidebushing is secured within the holder and used for cutting an inlay by reference to a female pattern. An appropriately shaped and sized recess is cut by reference to the female template while contacting the template with a tapered sleeve secured to the guidebushing. Movement of the guidebushing and sleeve along the axis of rotation of the router cutter permits adjustment in the size of the recess cut by reference to the template.

  • Patent number: 5711356
    Abstract: A template for use with a jig having a workpiece positioning member. The template supports and guides a cutting tool used to cut joint members in two workpieces and comprises a support surface and at least one set of guides formed on the support surface for guiding the cutting tool. The support surface is movable with respect to the workpiece positioning member a predetermined distance between a first position to cut joint members in one workpiece and a second position to cut complementary joint members in another workpiece. This arrangement permits accurate routing of rounded or square finger joints or other types of uniform, spaced joints as determined by the template being used. Moving the template with respect to fixed workpiece positioning members means that no adjustment of the positioning members or workpieces is necessary between cutting of complementary joint members on separate workpieces which tends to result in more accurate cutting of the joints.

  • Patent number: 5156508
    Abstract: A cam action clamp for use against a fixed clamping surface comprising a threaded shaft extending outwardly from the fixed clamping surface and a movable clamping member having a channel therethrough to allow the clamping member to be mounted on the threaded shaft for slidable movement along the shaft. A thrust plate is affixed to the movable clamping member adjacent the channel. A mounting block is threadably mounted on the threaded shaft and a clamping handle is pivotally mounted to the mounting block. The handle is formed as a cam member that abuts the thrust plate. Pivoting the handle causes the cam member to engage the thrust plate to slidably advance the movable clamping member along the threaded shaft toward the fixed clamping surface in order to clamp an article between the surfaces. The mounting block can be rotated along the threaded shaft to vary the distance between the clamping surfaces.

  • Patent number: 5123463
    Abstract: A jig for guiding a power tool having a cutter bit to cut joint members in workpieces includes a base frame having a tool support surface and a workpiece support surface. A pair of guide arms are releasably attachable to the power tool. A track is formed on the tool support surface adapted to slidably receive one of the guide arms. A template is releasably securable to the tool support surface having guide surfaces engagable by the other of the guide arms. The track and template co-operate to guide movement of the power tool atop the tool support surface. A clamping system is provided for securing workpieces to the workpiece support surface in a position to be cut by the power tool slidably supported on the tool support surface and guided by the track and the template to provide a joint member in one workpiece and a complementary joint member in another workpiece.

  • Patent number: 5114265
    Abstract: An interlocking joint for joining two panels together has curved jigsaw shaped indents and protrusions on edges of both panels that fit together and cannot pull apart. The indents and protrusions are cut by a router with a straight sided cutter. A template is provided for guiding a bushing on a cutter shaft of a router and the template takes into account the bushing having a larger diameter than the cutter. There is also a jig provided that has fingers that are asembled to cut out the interlocking joint with a router.

  • Patent number: 4750536
    Abstract: A waste attachment for a router. A first housing is connected to a vacuum source and attached to a router base. A second housing is slidably attached to the first housing. An arm extends from the second housing and ends in an inlet to receive router waste. The arm is used when the waste attachment is in its useful position on a router, into contact with the work piece being routed.

  • Patent number: 4428408
    Abstract: A jig used to support and guide a cutting tool has a base frame provided with an elongated support. Mounted on this support is a plurality of guide fingers which collectively serve as a template for the cutting of joint members in boards. The guide fingers are individually secured to the support so that the lateral spacing between the fingers is adjustable. Along one side edge of the support, the overhanging ends of the fingers are shaped to allow the cutting of common joint members. Along the other side edge of the support, the overhanging ends of the fingers are shaped to allow the cutting of complementary joint members. The jig has a clamping arrangement which allows the boards to be clamped to the base frame with the board ends disposed in selected positions relative to the shaped ends of the fingers.
