Abstract:
1. A drive link for a saw chain, comprising: a forward rivet hole and a rearward rivet hole, wherein the forward rivet hole and the rearward rivet hole define a first centerline that is generally parallel to a rail of a guide bar, and the forward rivet hole further defines a second centerline that is generally perpendicular to the first centerline, wherein the first centerline and the second centerline are generally coplanar with the drive link; a top edge comprising a tail portion having a trailing end tip disposed a first distance from the second centerline along a line perpendicular to the second centerline, wherein the tail portion is configured to substantially overlap and align with an upper surface of a cutting link depth gauge when the cutting link depth gauge is pivotally coupled to the drive link at the rearward rivet hole, as the drive link traverses a nose of the guide bar; and a concavity formed between the top edge and a trailing edge of the drive link, wherein the concavity has a forward-most portion disposed below the top edge and at a second distance from the second centerline along a line perpendicular to the second centerline, the second distance being shorter than the first distance.
