  • Woodworking plane
    Patent number: 4589209

The iron is also displaceable on each side of a midposition parallel to the contact surface of the plane and transversely with respect to the direction in which the plane travels. The iron is secured in a predetermined position by a support that has a holder against which the iron rests. A support component can be displaced transversely on a frame.
