Abstract: A supply of logs are successively transferred from an endless deck conveyor to a sawmill carriage by a log transfer rotor and log positioning cradles. The rotor includes a shaft supporting a plurality of axially spaced transfer elements each having diametrically opposed recesses for receiving logs. The log positioning cradles are arranged in parallel relation to the rotor and are supported for vertical movement by corresponding fluid cylinders. The log transfer rotor and deck conveyor are independently driven by corresponding motors which are operated in timed relation by an automatic control system.

Abstract: The specification discloses a sawmill arrangement in which a log carriage is provided which is suspended from a horizontal rail located above the carriage with the log being suspended on the carriage therebeneath. The carriage has dogging elements thereon to engage the ends of the log and which are rotatable for turning the log. Controls are provided for controlling the reciprocation of the log carriage and the feeding of the saw toward and away from the path of the log. Two saws may be employed, one running on each side of the center of the mill for cutting slabs or boards from both sides of the log. Each saw may have associated therewith edging saws for edging the slabs or boards taken by the main saws of the machine.

Abstract: As boards are being cut from a log, they are moved over an inclined slide. When fully cut away from the log, the boards fall down the slide away from the cutting area. To insure that longer boards are moved away from the saw blade a horizontal shelf may be mounted on the slide for temporarily supporting the leading end of the board. As the trailing end of the board is cut free, it falls down the slide and pulls the leading end off the shelf. The slide is shown in association with two board handling systems. In one system a stop and dump assembly including arms for receiving the freshly cut board is mounted at the base of the slide. The arms are movable for also stopping the boards on the slide and for dumping trash therefrom. The other system includes a screw roll conveyor mounted at the base of the slide adapted to convey cut boards longitudinally of the screw roll conveyor and parallel to the travel of the log from which the board is cut. Immediately adjacent the screw roll conveyor is a chain conveyor for conveying boards in a direction perpendicular to the movement of the log. To position the boards on the chain conveyor, one of the screw rolls remote from the saw blade is moved to an upper position to stop boards from moving longitudinally of the screw roll conveyor. The raised screw roll is still rotated so that it, along with the other screw rolls, tends to cam or convey the freshly cut boards in a direction perpendicular to the rotation of the rolls and onto the chain conveyor.
