Abstract
Abstract An automatic lumber feeding device to be used in combination with a wood working machine such as a hand feed planer or the like. The lumber feeding device comprises a fixed bracket, a free bracket mounted to the fixed bracket at a certain angle and a roller shaft head arranged to be at right angles to the free bracket. The roller shaft head supports a rotatable roller shaft to which a feed roller is fastened. The free bracket is reciprocally movable along the fixed bracket in the longitudinal direction thereof, and the position of the roller shaft head relative to the free bracket is adjustable. The feed roller attached to the roller shaft is rotated by means of a driving motor or by other means so as to feed lumber with a surface thereof being pressed by a press surface of the feed roller. The lumber feeding device is attached to a ruler member vertically provided on a working table of a wood working machine.
