Abstract: A saw chain is disclosed which includes cutting links having a central pivot on the bottom or inner edge of such cutting link which contacts the track of a saw bar on which the chain is mounted. A front foot portion and a rear foot portion which extend from the central pivot to the front end and the rear end, respectively, of the cutting link are normally spaced from such track when it is not cutting. The cutting link tilts about the pivot rearwardly and forwardly during cutting to provide a smooth rocking motion which reduces vibration and injury to the operator. One embodiment of the cutting link employs a single pivot located centrally between the front rivet opening and rear rivet opening. Another embodiment of the cutting link employs two pivots which are spaced apart and are both located centrally between the front and rear rivet openings. The saw chain includes side cutting links and side tie strap links connected by rivets to central drive links.

Abstract: A saw chain length including articulated alternating center drive links and side links. Cutting links provide certain of the side links and a safety side link precedes each cutting link. The safety side link and its opposing tie strap link have shaved heel portions and thereby are raised off the guide bar when normally tensioned around the guide bar. The safety link is configured whereby engagement thereof by material being cut during a cutting operation induces pivoting of the safety link against the opposing tension force, which tension force thereby absorbs the impact prior to said heel portions engaging the guide bar edge.
