ABSTRACT:
A self-adjusting, self-locating chain stop mechanism having a pawl with a notch for receiving the rearward edge of a cutter link of a saw chain is secured to a holder which supports the saw chain in position for sharpening a selected cutter link using a disc-shaped grinding wheel. The movement of the pawl is restricted within a preset range determined by the size of the saw chain to be sharpened, the range of movement permitting the saw chain to be advanced after each cutter link is sharpened without interference from the pawl and preventing movement of the cutter link being sharpened when backed up against the notch on the pawl.
