TOOTH JUMPER DEVICE FOR SPROCKET CHAINS Presented is a tool and method for use in conjunction with chain conveyors of the type for transporting lumber from one work station to another. Lugs spaced along the chains usually remain in transverse alignment and usually similarly orient the lumber, but the chains sometimes become de-synchronized, causing the lugs to become misaligned, and the lumber unoriented on the conveyor. The tool is clamped on the drive sprocket of the chain that is out of synchronism and the sprocket is rotated, causing the chain to advance one tooth for each revolution. Rotation is continued until the de-synchronized chain is again synchronized with adjacent chains, and the lugs carried by the chains again transversely aligned.
