ABSTRACT:
A support is provided and a rotary grinding head is journaled from the support for rotation about a first predetermined axis. A support arm is pivotally mounted at one end from the support for swinging of the support and support arm about a second axis substantially paralleling the first axis and the other free end portion of the support arm includes structure for supporting a saw chain therefrom for successive positioning of the cutting teeth of the chain in predetermined position for sharpening by the grinding wheel. As a result of relative swinging of the support and the support arm, the rotary grinding head is swingable into registry opposite side portions of the supported saw chain. Also, a chain tooth engaging and positioning member is supported from the support arm for establishing the predetermined position of the tooth to be sharpened and is swingable into and out of an operative position. When the rotary grinding head is positioned at one side of the supported saw chain, all of the cutting teeth on that side of the chain may be successively sharpened and when the grinding head is positioned on the opposite side of the supported saw chain, all of the cutting teeth on that side of the chain may be successively sharpened.
