ABSTRACT:
An apparatus using an abrasive belt is employed for sharpening ice skates quickly and accurately to any one of a variety of different hollow ground curvatures. The abrasive belt is mounted on pulleys and driven at a high speed across a changeable head which shapes the belt to the desired curvature for grinding a skate edge moved longitudinally thereagainst. The skate is mounted by means of a clamp so as to present the blade edge in a precise grinding position with respect to the belt and the head. The clamp is slidably mounted on the top of a carriage moveable along a guideway parallel to the head, whereby a blade edge may be brought to bear in a movement corresponding to the profile of the blade edge. The head may be changed to different positions in order to present different curvatures in the belt, depending upon the radius of curvature desired in a skate edge.
