  • Patent number: 4507998
    Abstract: Logs which have previously been de-limbed are placed onto and removed from a loading deck one at a time and delivered to an aligning trough or mechanism where one end of all logs are moved to a common point. The logs are then conveyed one at a time by a feed conveyor in a direction transverse to the longitudinal axis of the logs and presented to a sawing mechanism where each log is sawed simultaneously into a plurality of shorter firewood pieces. The sawing mechanism includes a plurality of circular saws spaced longitudinally along a common axis which is, in turn, spaced above the level of the feed conveyor and extends parallel to the longitudinal axis of the logs. Each saw is individually mounted for ease of removal and adjustment. A spring device urges the log downwardly, while lugs on the feed conveyor at the same time urge the log forwardly through the sawing mechanism.
