    • A chain saw guide bar (14) for guiding an endless saw chain (16) has a sprocket (30) rotatably mounted in the nose (28) of the bar (14) to elevate and transport the saw chain (16) around the nose end. The teeth (34) of the sprocket (30) engage the drive links (50) of the chain (16) to lift the chain off the nose edge (25) as the chain (16) traverses the nose (28). The tooth tips (40) project above the side link bearing surfaces and into configured notches whereby the teeth (34) effectively provide the lifting action without entering the saw chain chassis.
