    Abstract: A set of log support carriage units are supported for horizontal movement by a set of parallel spaced tubular tracks and are connected by an elongated hydraulic cylinder. The carriage units include depending plate-like brackets which support corresponding dog members for engaging the opposite ends of a log when the connecting cylinder is retracted. The main carriage unit includes a variable speed hydraulically driven resilient wheel. The wheel engages the bottom surface of one of the tracks and is effective to move both of the carriage units along the tracks for feeding the log into a pair of rotary saws of a corresponding set of laterally adjustable saw husks. The dog member of the main carriage unit is mounted on one end of an elongated horizontal shaft rotatably supported by the corresponding bracket. The opposite end of the shaft connects with a hydraulic motor which is also supported by the bracket and is controlled by valves positioned adjacent a rotary actuator driven by the shaft through an electrically actuated clutch. The log is rotated to a selected position for the initial cutting operation and is then automatically indexed by precisely 90* from the initial cutting position.

    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.
