Abstract: Herein disclosed is a carpenter planer in which a stock is cut during the reciprocative motion on a stock feeding table. The stock to be cut is reciprocated by a stock feeding unit above the stock feeding table, which is driven by a reversible motor. A detector for detecting the passage of the stock to change the forward or reverse rotation of the motor is provided on the side of the feeding table. The detector is adapted to emit a signal toward the side of the stock and to receive the reflected signal from the stock. With the detector is connected a timer for preventing the detector from malfunction even if the reflected signal has not been received by the detector for a predetermined period of time due to irregular reflection of the signal on the stock.

Abstract: A wood-planing and finishing machine in which a cutting tool is secured to a knife stock through a mounting plate. The mounting plate is mounted on the inclined mounting surface of the knife stock in such a manner that the tilting angle of the former, and therefore its vertical position, can be adjusted by means of a wedge member. The degree of projection of the tool increases when the upper end of the mounting plate is tilted upwardly, and decreases when it is tilted downwardly. The mounting plate is secured by the wedge member against tilting and vertical movements resulting from a resisting force acting on the tool during operation.
