The pockets 36 which receive the drive tangs of the saw chain have enlarged portions, or bores, 40 opening radially outwardly from the sprocket, which bores are wider than the side-to-side dimension of the side links on the chain to allow debris to clear radially from the pockets past the sides of the chain during operation. The sprocket also may have axial ports 46 intersecting the radially disposed bores. <IMAGE> |
