ABSTRACT:
A drive sprocket for use with an elongate, endless saw chain, the sprocket being a substantially circular member having pockets spaced circumferentially thereabout for receiving drive tangs on the saw chain and edge margins adjacent the tang-receiving pockets against which surfaces of side links of the saw chain may rest. The pockets have enlarged portions, or bores, 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 intersecting the radially disposed bores.
