ABSTRACT:
A generally horizontal elongated mount is provided having structure on one end for supportive anchoring from one marginal edge portion of a workbench with the other end portion of the mount projecting outwardly of the bench marginal edge portion. A depending support leg is carried by the mount spaced intermediate the opposite ends thereof and the lower end of the leg is adjustably extendible for supportive engagement from a floor surface. A support shaft generally parallels the mount and is supported therefrom for adjustable angular displacement relative thereto about the longitudinal axis of the shaft and the end of the shaft corresponding to the one end of the mount oscillatably supports one end of a swing arm therefrom for angular displacement relative to the shaft about an axis transverse to the swing arm and the shaft and angularly adjustable with the shaft. The free end of the swing arm journals a motor driven grinding wheel therefrom for rotation about an axis transverse to the swing arm and the other end of the mount is disposed beneath the free end of the swing arm and supports an elongated grooved saw chain support structure therefrom for adjustable angular positioning about a vertical axis shiftable laterally of the mount. Further, structure is provided whereby the free end of the swing arm is biased laterally to take up slack in the pivot connection between the swing arm and the shaft as the swing arm other end is swung toward the saw chain support structure.
