Abstract
A nose sprocket for the saw chain of a chain saw includes radially projecting teeth, each tooth having leading and trailing edges. Each of those edges includes a straight inner portion and an outer portion that deviates from a radius of the sprocket by a greater amount than the inner portion. The teeth are long enough to enter a space formed between side links of the saw chain.
