Abstract:

A guide arm for a gang sawmill is provided adjacent to an inlet of a gang saw and is movable about a pivot pin depending on the actual curvature of a cant to adjust (continuously or fixed) the position of an incoming cant to maximize the yield of usable boards produced by the gang saw by moving the cant relative to the saw as a conveyor feeds the cant through the gang saw.

Abstract:

A spiked H-style link for a sharp chain conveyor where the single centrally-placed saddle of the prior art is replaced by a double saddle with a centrally-located opening shaped to receive a sprocket tooth. The double saddle moves each saddle outward from the central portion of the spiked link to enhance the rigidity of the legs between which the connecting pins act. The legs are provided with a thickened offset step on the lower inner portion of each leg. There is a corresponding decrease in the thickness of the legs in the region where the connecting link works. By decreasing the thickness of the legs in the region outside the offset step, the connecting link may be widened, allowing for a greater bearing surface on the connecting pin and thus reducing the rate of wear on the connecting pin.
