There is provided an apparatus for sharpening ice skates, which includes means for supporting the blade in a fixed location, and means for moving a rotating grinding member along the blade, with the grinding member rotating about an axis parallel with the plane of the blade. The guide means are provided to allow the grinding member to follow a predetermined profile. The guide means include a gearing arrangement which rotates a cam shaft as the carriage supporting the grinding member moves longitudinally of the blade. A pivotal arm supporting the grinding member has a cam follower which is raised or lowered by the cam surface, to cause the grinding member to follow the predetermined profile.

A skate sharpening apparatus, comprising: first means for firmly supporting a skate blade, a grinding member having the shape of a surface of revolution, power means for rotating the grinding member about its axis of symmetry, second means supporting the power means for pivoting movement about a pivotal axis transverse to said axis of symmetry, the pivotal axis being spaced from the grinding member, guide means for allowing relative translational movement between the first means and the second means, and cam means controlling the pivotal position of the power means as a function of the translational position of the first means relative to the second means, the cam means being such as to cause the grinding member to follow a locus corresponding to a pre-determined skate blade profile, said cam means including a gear rack fixed with respect to said first means, a pinion meshing with and rolling on said rack, the pinion axis being transverse to the direction of translational movement and being fixed with respect to said second means; and means including a reduction gear mechanism for applying the rotation of said pinion to a cam shaft whose axis is fixed with respect to the second means whereby the cam shaft rotates more slowly than the pinion, a cam on said cam shaft, a follower mounted on the power means and bearing against the cam, the cam being contoured such that the follower causes the grinding member to follow the profile of a skate blade supported in said first means.
