ABSTRACT:
A wood handling machine for handling stacked layers of board lumber to facilitate marking the boards comprising essentially a support bed for supporting a stack of boards in layers, a fluid pressure operated clamping device to clamp the stack and hold it in alignment, a pushing device at one end of the stack for pushing at least one layer at a time of the boards a predetermined distance to expose the surface of the next layer of boards for marking, and a stop bar at the other end of the stack to prohibit the movement of the next adjacent layer of boards during the operation of the pushing bar. The pushing bar is provided with an indexing means which automatically controls the incremental movement of the push bar a distance comparable to the thickness of the layer of boards. Fluid pressure cylinder and piston devices are used in combination with valves in a fluid pressure circuit for controlling and operating the pushing bar and stop bar and raising and lowering them into the predetermined desired position.
