  • Patent number: 9168626
    Abstract: A tool sharpening assembly suitable for sharpening cutting tools. In accordance with some embodiments, the apparatus has a rotatable abrasive surface, and a tool support structure which contactingly supports a body portion of a tool while a cutting surface of the tool is presented against the abrasive surface during a sharpening operation. A cooling mechanism operates to reduce a temperature of the tool.

  • Patent number: 8512103
    Abstract: A tool sharpening assembly (100) suitable for sharpening cutting tools (140,350,366,546,562). In some embodiments, a wedge-shaped port is formed between a rotational first abrasive surface (160,262) and a stationary second abrasive surface (162,264) to sharpen a distal cutting edge (146) of a cutting tool (140,230,546). In other embodiments, a cooling mechanism (136,326,330,334,338) actively draws heat generated during a sharpening operation from a tool (140) and through a tool support structure (170,234,328,332) contactingly supporting the tool, in further embodiments, a rotatable abrasive slotted disc (364) comprises at least one inspection aperture (372) formed from an interior sidewall (390) with upper and lower leading and trailing edges (396,398,400,402) of non-uniform separation distance. In other embodiments, a cylindrical drum abrasive member (572) is provided with an associated stationary support plate (574).

  • Patent number: 8388413
    Abstract: Apparatus and method for sharpening a tool, such as a chisel. A sharpening guide applies a clamping force to secure the tool and advances a beveled leading edge surface of the secured tool against an abrasive surface to sharpen a cutting edge while the guide is in an upright orientation. An alignment plate nestingly receives the guide in an inverted orientation to align the tool prior to sharpening. During alignment, a back surface of the tool slidingly contacts an upper plate surface and the cutting edge contactingly abuts an alignment feature which projects from the plate surface. In some embodiments, the alignment feature comprises a removable alignment pin selectively insertable into a plurality of spaced apart apertures, each providing a final bevel angle for the sharpened tool.
