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.
