Abstract: Ice skate-sharpening apparatus including a housing assembly carrying a vertically extending drive shaft on which a grinding wheel is mounted. Adjustable mounting means supports the housing assembly on a work table for vertical movement with respect to the work table to position the grinding wheel at a predetermined work-performing position above the work table. Drive transmission means connects the grinding-wheel drive shaft with a motor that is fixedly mounted at a position adjacent to the work table. The drive transmission means provides for the rotation of the grinding wheel in any of a plurality of vertical positions spaced above the work table. The housing assembly also carries a wheel-dressing tool which is simply moved to a wheel-dressing position.
