Abstract
A scissors sharpening apparatus includes a motor driven sharpening member having an abrasive surface. A magnetic guide is arranged to position the scissors blade at a fixed angle relative to the principle plane of the abrasive surface in such a manner that the magnet of the guide has the axis of its poles oriented nominally perpendicular to the flat face of the blade and nominally parallel to the principle plane of the abrasive surface.
Claims7
A scissor sharpening apparatus for sharpening a scissor blade comprising a ferromagnetic disk having an abrasive surface, motor means for rotating said disk, a magnetic guide means for positioning the scissor blade at a fixed angle relative to said abrasive surface, said magnetic guide means including a magnet having magnetic poles oriented with their axes nominally perpendicular to the flat face of the blade and nominally parallel to said abrasive surface, and said magnetic guide means being juxtaposed and slightly spaced from said abrasive surface for supporting the blade in contact with said abrasive surface whereby a magnetic current may flow from said magnet and through the blade and through said metallic disk and back to said magnet to maintain the blade in contact with said abrasive surface.
