ABSTRACT:
A support plate is provided and includes a pair of intersecting adjacent side marginal edges disposed at generally 100.degree. to 120.degree. relative to each other and provided with endwise outwardly opening grooves formed therein communicated with each other at adjacent ends. The plate includes a transverse bore formed therethrough whereby the plate may be oscillatably supported from a swingable arm of a saw chain sharpener for movement of the plate toward and away from the rotary grinding wheel of the sharpener. Adjustment structure is supported from the plate for adjustably limiting angular displacement of the plate in one direction relative to the corresponding swing arm. The grooves formed in the plate are provided to guidingly and slidingly receive the guide lugs of an associated saw chain and the plate includes adjustable abutment structure engageable with successive saw chain teeth to limit shifting of an associated saw chain relative to the plate along the grooves.
