ABSTRACT:
An upstanding support is provided and a rotary grinding head is journaled from the upper end of the support for rotation about a vertical axis. A horizontally disposed support arm is pivotally mounted from the support at one end portion for swinging about a vertical axis and the other free end portion of the support arm has a grooved support wheel journaled therefrom for rotation about a horizontal axis extending transversely of the support arm. The grooved support wheel may have a saw chain trained thereover and the grooved support wheel, during oscillation of the support arm, is swingable into registry with diametrically opposite side portions of the rotary grinding head. Also, a chain tooth engaging and positioning member is supported from each of the opposite side portions of the support arm adjacent the grooved support wheel and swingable into and out of an operative position. When one side of the support arm is swung toward registry with one side of the rotary grinding head the positioning member on that side of the support arm is swung to the inoperative position and the positioning member on the opposite side of the support arm is utilized to engage and properly position a chain tooth on the upper periphery of the grooved support wheel for movement of that tooth toward engagement with the rotary grinding head.
