  • Patent number: 5934138
    Abstract: The present invention provides tools and methods for bending angle stock, a tool including first and second parallel facing plates and a third plate holding the first and second plates in a fixed position. The third plate is fixed to upper edges of the first and second plates, and the first and second plates are separated by a gap sized to receive a side of the angle stock. The first plate has a back surface to which is attached an end of a rod-shaped handle. A bend in the angle stock is made by first cutting one side of the angle stock at a desired bend point on the other side and then placing two of the tools on the uncut side, one on each side of the desired bend point. The handles of the tools are pushed together to form a 90.degree. bend in the angle stock, which is formed because the edges of the first plates that are adjacent to the desired bending point have a 45.degree. angle. With this edge, a right-hand tool contributes a 45.degree. bend and a left-hand tool contributes a 45.degree.
