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. The loading conveyor includes a pair of aligned but spaced conveyors which enables short wood or logs to be discharged from the loading conveyor so that only the desired cut length logs will be carried by the loading conveyor to a truck body or other area adapted to receive the cut length logs.
A wood cutter and loader comprising a supporting framework, a plurality of spaced and aligned circular saws supported from said framework, a plurality of conveyor chains supported from said framework, means on said chains for engaging a tree length log and moving it toward the saws when the chains are driven, said chains being endless and entrained around end sprockets, one of said sprockets being disposed immediately adjacent the lowest peripheral point of an associated saw, each of said saws including a spring biased log engaging latch extending beyond the periphery of the saw to engage the top surface area of an approaching tree length log to stabilize the log and prevent kickback, loading conveying means supported on said framework at an elevation below the sprocket adjacent the lowest point of the saw to enable cut length logs to free fall onto the loading conveyor means immediately after the saw has cut through the tree length log thereby reducing binding and friction on the saws, and means driving said chains, saws and loading conveying means.
A wood cutter comprising a supporting framework, a plurality of spaced and aligned circular saws supported from said framework, a plurality of conveyor chains supported from said framework, projections on said chains for engaging a tree length log and moving it toward the saws when the chains are driven, said chains being endless and entrained around end sprockets, one of said sprockets being disposed immediately below the lowest peripheral point of an associated saw to enable cut length logs to move downwardly away from the saws immediately after the saws cut through the tree length log thereby reducing binding and friction on the saws, each of said saws including a log engaging means associated therewith in opposed relation to the chains and projections thereon to engage the top surface of an approaching tree length log to stabilize the log and prevent kickback when the saws are cutting the log and means driving said chains and saws, said log engaging means including an elongated, generally straight bar disposed above the projections on the chains and below the rotational center of the saws, and spring means retaining said bar in position and enabling upward movement thereof when a log engages the bar, said bar extending beyond the periphery of the saws and cooperating with the projections to stabilize the log when engaged by the saws.
