  • Patent number: 4259886
    Abstract: A trailer mounted wood cutter and loader for cutting tree length material or logs into pulpwood, saw logs, and the like. The wood cutter and loader includes a framework supporting a plurality of conveying and feeding chains having outwardly extending concave log engaging latches thereon for receiving a tree length log and moving it transversely to feed the logs under a plurality of overhead saws with the cut lengths of logs free falling unto a loading conveyor. A spring loaded latch assembly is associated with the saws to catch or engage the tree length material prior to the saws engaging the tree length material. The chain mounted latches combined with the spring loaded latches and a slight upward incline of the conveying and feeding chains co-operate to prevent kickback of the cut length logs and to prevent binding of the logs in relation to the saws.
