Abstract
A chain saw bar nose has a rotatable sprocket. The sprocket assembly is adapted to conform in shape to the drive tang portions of the saw chain whereby the nose sprocket may receive operational forces imposed by the saw chain substantially as compressive forces as opposed to tensile forces. As a result, the nose sprocket assembly better withstands the harsh operating conditions imposed by cutting applications.
