Description:
Described by Hartness and Tower as an improvement of Orril R. Chaplin's patent (126519), the focus of this patent is on the method of attaching the cap-iron to the plane-iron so that it won't shift with the lever cap when the iron is adjusted for heavier and lighter cuts. Noted as especially useful for wood-bottom planes.
