A machine for sharpening the blade of an ice skate has a vertically mounted, thin grinding wheel with a convex transverse cross-section corresponding to the concave transverse cross-section desired for the blade edge. Clamping plates on a cradle hold the blade above the wheel with their central planes coplanar and with the wheel biased against the blade. The cradle is pivotable about a horizontal axis above the skate so that the skate can be swung in an arc. Hence the movement of the blade over the wheel takes place in an arc that is curved in the same d...
In a machine for sharpening the bottom edge of the blade of an ice skate, said edge having a convex profile in side view, comprising (a) a thin grinding wheel having a periphery with a convex transverse cross-section corresponding to a desired concave transverse cross-section of said blade edge, (b) means for rotating said wheel about its axis, (c) means for clamping said blade, and (d) traversing means for effecting relative movement between the clamping means and the wheel in the longitudinal direction of the blade with the central longitudinal plane o...
