Thomas E. Daniels, 1800-1867
Daniel�s Plane
Two small gold stars for Dan and Tom
In 1834, Daniels patented a machine face-jointer that was, at least in America, the first successful mechanization of the process of flattening boards and lumber. His design was used for many years, often in combination with the Woodworth planer, which machined a second face parallel to the first. The Woodworth planer could not be used by itself to create a flat face, because the pressure of the feed rollers tended to flatten the board, which would spring back after it had been planed. The Daniels planer consisted of a reciprocating carriage on which the lumber was secured; the lumber was shimmed as necessary so that it could not rock or twist while being planed. A pair of cutters were mounted on either end of a horizontal bar that was suspended from a vertical spindle above the stock. This vertical spindle rotated rapidly, removing material from the stock so that the upper face of the stock is flattened (except for circular score marks similar to those left behind by a circular saw).
