ABSTRACT:
An elongated frame supports a pair of rails for a wheeled log carriage. A winch drum is mounted on the frame between the ends of the latter and drives a cable reeved through opposite end pulleys for moving the carriage in feed and return movements. Multiple pulley V-belt assemblies are provided in the drive unit for the carriage and are operated by a manual lever which in one direction actuates feed movement of the carriage and releases return drive movement and in the other direction of the lever releases the drive for the feed movement and actuates the drive for the return movement. Such actuation and release of the multiple pulley V-belt assemblies is controlled by rocker arm clutches controlled by the manual lever. A log ramp is utilized with the mechanism and has a pull cable powered from the main drive mechanism of the sawmill under control of an operator's lever. A sawdust pickup housing is combined with the saw blade to catch sawdust and a conveyor associated with the pickup housing and driven from the main power drive of the saw delivers the sawdust to the opposite side of the machine for loading into a vehicle.
