ABSTRACT:
Chain saw bars having overlapping slots adjacent locations where the saw chain leaves the driving sprocket and in the region of the nose end of the bar are provided. In these areas, where the chain tends to pound against the bar, the slots dampen the vibrations between the outer portions of the bar rails and the interior of the bar and greatly reduce noise emission. The slots also provide cooling of the saw bar.
