  • Publication number: 20130199671
    Abstract: An improved design for a featherboard. The featherboard exerts lateral pressure against a work piece, keeping it pressed against a guide fence of a power tool for improved accuracy of cut. The featherboard consists of a bracket, which can be fixed to and removed from the worktable without tools. It has one or more attachment posts. The bracket also has a guide that accepts a featherboard arm that can be locked in place with a locking knob when it is in the desired position. At the end of the featherboard arm is one or more flexible plates with guide marks. When the featherboard arm is properly positioned the flexible plate(s) is/are pressed into the work piece to hold the work piece against the guide fence and to prevent kick back of the work piece by the saw.

  • Patent number: 6962179
    Abstract: A bending jack for straightening bent boards. The device has three main components: a spur assembly that has a spur head, a spur bar and a spur; a handle, secured to the spur bar by a pivot pin or bolt; and a push arm. At one end of the push arm is a shoe. The other end of the push arm is pivotably attached to the handle. The device is used by driving the spur into a joist near a bent board. The device is set so that the shoe is near the spur and abuts against the board. As the handle is then moved forward it pushes the shoe against the board. Because the spur is fixed in the joist, the board is moved in the direction of the handle movement. Once the board is secured, the device can be pulled from the joist, ready for the next operation.
