Abstract

A device and method for contouring and sharpening an ice skate blade. The device uses a fixture for holding the ice skate. The fixture employs retractable depending cam rollers to be guided by cam templates recessed into the top surface of the table of the machine. The cam templates are coverable when not in use, thus increasing the usefulness of the top surface of the table. The grinding wheel is movable into and away from the fixture. One of the cam rollers is mounted to an eccentric wheel for pitching the ice skate blade in relation to the grinding wheel. The method comprises the steps of clamping a skate into the fixture, retractably depending or lowering the cam rollers to engage the cam templates in the table of the machine, adjusting the cam roller by operating the eccentric to achieve the desired pitch, moving the grinding wheel to the fixture holding the ice skate and contouring or sharpening the ice skate.

Claims

1. An ice skate sharpening fixture having means for retaining an ice skate therein, the fixture having follower means thereon, the ice skate sharpening fixture comprising

a base plate, the base plate having a planar underside,

the follower means being movable above and below the planar underside of the base plate, and

means for radially adjusting the follower means for pitching the blade of an ice skate held in the fixture, wherein the means for radially adjusting the follower means comprises an eccentric device on the follower means, wherein the follower means comprises a roller.

2. An ice skate sharpening device for placement on a flat surface having a top edge and means for directing recessed below the top edge of the flat surface, the device comprising a fixture according to claim 1 having means for retaining an ice skate therein, the fixture having follower means thereon, the ice skate sharpening device being placeable on the flat surface,

means for directing the follower means, the means for directing the follower means being interengagable with the follower means and the means for directing the follower means being recessed below the top edge of the flat surface.

3. An ice skate sharpening device according to claim 2 further comprising a means for sharpening, the means for sharpening being movable into and away from the fixture.

4. An ice skate sharpening device according to claim 2 further comprising

means for covering the means for directing the follower means, the means for covering fully covering the means for directing, thereby making a contiguous flat surface.
