Device for dressing grinding wheels

Abstract

A movable frame assembly to move a device for dressing a grinding wheel for the sharpening an ice skate blade. The device uses a housing surrounding a grinding wheel and movable frame with a swing arm. A dressing tool is mounted in the dresser swing arm and the dresser swing arm is rotatable between a storage position and an operating position. The movable frame assembly slides along rails to allow positioning of the dressing tool into the grinding wheel. Horizontally and vertically disposed bearings are positioned beside and under a rail with resiliently biased bearings are held against the top of the rail. The bearings help the rails of the movable frame move smoothly. The rails are spaced apart by yokes on the arm or a bar across the top of the dresser to prevent binding as the movable frame is slid for dressing the wheel. Adjustment of the rails is also provided for by adjustment slots at the back of the rails.
