Historical Information about Razee Smoothing Plane


Patent illustration from patent obtained by Daniel Heald, son of the maker, in 1878, for an elegantly simple plane iron cap. According to Instruments of Change, p. 33, "this patented device apparently evolved from Daniel Milton Heald's earlier pivoted wooden wedge and tightening screw. In the fully developed invention, the cast-iron plane iron cap is pivoted on a steel pin. A steel screw penetrates a slide in the cap and holds the double plane iron. A second screw permits the vertical adjustment of the slide, moving the plane iron in or out of the mouth of the plane."
