Apparatus for sharpening implements

Apparatus for carrying out the sharpening of implements having a body portion and an edge for sharpening in conjunction with a bench grinder positioned upon a work surface having a motor, a shaft axis and oppositely disposed circular grinding wheels, rotatable about said shaft axis, spaced a predetermined distance from said motor and having a grinding surface, comprising:

• a base member supportable by said work surface and being adjustably positionable along a path substantially transverse to said shaft axis to select positions adjacent said bench grinder intermediate said spaced grinding wheels;
• a hinge fixed to and movable with said base member and having oppositely disposed sides, a hinge axis spaced upwardly from said base member, said hinge being pivotally movable about said hinge axis from a rearward mount position to forward grinding positions;
• a guide rod assembly mounted upon and movable with said hinge about said hinge axis and extending to end locations from each said hinge oppositely disposed sides a select distance greater than said predetermined distance;
• a carriage having at least one bearing mountable upon said guide rod assembly, said carriage being laterally movable upon said bearing across said guide rod assembly between a said hinge side to a corresponding said end location, said carriage having a bracket member selectively pivotal thereon about a bracket axis perpendicular to said hinge axis;
• and
• a gripping component mounted upon said carriage bracket member and hand actuable for receiving and removably retaining said implement body portion and pivotally movable with said carriage and said guide rod assembly to locate said edge in grinding association with said grinding surface when said hinge is moved to a said forward grinding position.

Apparatus for carrying out the sharpening of implements having a body portion and an edge for sharpening in conjunction with a grinder assembly including a grinding wheel drivably rotatable about a shaft axis above a work surface, comprising:

• a base member supportable by said work surface and being adjustably positionable along a path substantially transverse to said shaft axis to select positions adjacent said grinder assembly;
• a hinge assembly including a hinge mount fixed to and movable with said base member and a hinge mounted upon said hinge mount at a location spaced from said base member and pivotally movable about a hinge axis from a rearward mount position to forward grinding positions;
• first and second mutually spaced and parallel guide rods mounted upon said hinge, movable therewith and having rod axes generally parallel with said hinge axis and extending to end locations positioned outwardly of said grinding wheel when said base member is mounted upon said work surface;
• a carriage having bearings mountable upon said first and second guide rods, said carriage being laterally movable upon said bearings across said guide rods between said hinge and said end locations;
• and
• a gripping component mounted upon said carriage for receiving and removably retaining said implement body portion and hand actuable to pivotally move said carriage, said first and second guide rods with said hinge about said hinge axis to a said forward grinding position to locate said edge in grinding association with said grinding wheel.
