    摘要： An apparatus for sharpening knives, and the like where fixed abrasive elements on an orbiting surface in contact with the knife cutting edge facet move in a mechanically generated uniform cyclic orbit of circumference less than about one (1) inch and through that motion provides the work and energy to sharpen the knife or blade edge. The apparatus provides a circumferential velocity of the abrasive element of less than 800 feet per minute and restrains motion of the abrasive surface to less than ± .005 inch in a direction perpendicularto the intended plane of the knife or knife edge facet. The apparatus contains novel magnetic and other means to steady, guide and control position and angle of the face of the blade relative to the orbiting abrasive elements, to realign any burr or sharpening debris on the knife edge, to control in part the abrading forces, and to remove sharpening debris from the abrasive surface and sharpening zone. A means used to create the orbital motion of the abrasive surface utilizes a pair of synchronously driven eccentric cranks that engage an orbiting drive plate that supports the abrasive surface or surfaces, where the eccentric cranks are mounted on or are an integral part of the shafts of two gear pulleys driven syncronously by means of a motor-driven timing belt, and where the supporting drive plate is constrained to orbit in a prescribed principal plane by means of fixed bearing support points.

    摘要： A scissors sharpening apparatus includes a motor driven sharpening member (23) having an abrasive surface. A magnetic guide (33) is arranged to position the scissors blade (27) at a fixed angle relative to the principle plane of the abrasive surface in such a manner that the magnet of the guide (33) has the axis of its poles oriented nominally perpendicular to the flat face of the blade (27) and nominally parallel to the principle plane of the abrasive surface (23).

    摘要： Grinding fixture for grinding scissors by means of a ro­tatable grindstone (1) using an adjustable support arm (3) arranged at the grindstone base and extending transversely of the grindstone (1) in parallel with the axis thereof. Accord­ing to the invention the grinding fixture comprises a support plate (4) movably and rotatably fixable to the support arm (3), a first clamping plate (7) abutting on the support plate (4) freely movably as well as at least one second clamping plate (10) having a clamping edge. One blade (15) of a pair of scissors to be ground can be clamped between the clamping edge and the first clamping plate (7) be means of one or more screws (12, 13).

    摘要： A small and portable apparatus for sharpening the blades of a pair of scissors is provided according to the invention. The scissors sharpener comprises a main body; a vertically-oriented, stationary sharpening steel having opposed surfaces that is securely attached to the main body; a pivotable sharpening steel that rotates with respect to the main body; and a U-shaped return spring positioned between the main body and the pivotable sharpening steel. A user inserts a pair of scissors so that the inside surfaces of the two blades abut the opposed surfaces of the stationary sharpening steel for stable alignment, and closes the blades against the pivotable sharpening steel to cause it to travel along the blade cutting edges to sharpen them. When the scissors blades are disengaged from the scissors sharpening apparatus, the return spring will bias the pivotable sharpening steel back to its standby position.
