ABSTRACT:
A sawmill for cutting finished boards from logs in a single operation. The log is mounted on a reciprocating carriage which is also laterally adjustable to control the thickness of each board. Two vertically adjustable circular chippers are mounted on a vertical shaft. The spacing of the chippers controls the width of each board. A vertical saw is positioned with respect to the chippers so that the sides of the saw cut made through the log span the vertical cuts made by the chippers. The operation produces a maximum of sawdust.
