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.

Abstract: A device and method for contouring and sharpening an ice skate blade. The device uses a fixture for holding the ice skate. The fixture employs retractable depending cam rollers to be guided by cam templates recessed into the top surface of the table of the machine. The cam templates are coverable when not in use, thus increasing the usefulness of the top surface of the table. The grinding wheel is movable into and away from the fixture. One of the cam rollers is mounted to an eccentric wheel for pitching the ice skate blade in relation to the grinding wheel. The method comprises the steps of clamping a skate into the fixture, retractably depending or lowering the cam rollers to engage the cam templates in the table of the machine, adjusting the cam roller by operating the eccentric to achieve the desired pitch, moving the grinding wheel to the fixture holding the ice skate and contouring or sharpening the ice skate.

Abstract: A device and a method for contouring an ice skate blade. The method comprises the steps of measuring the overall length of the soleplate of the boot and calculating the center point of the soleplate, transferring the center point of the soleplate to the blade and marking the center point of the soleplate onto the blade as the first calibration point. A second and third calibration point, calculated as 25% of the soleplate length are marked from the first calibration point towards the toe and towards the heel of the blade. Toe and heel radius termination points are also marked. The device comprises a measuring tool for measuring the length of the soleplate and having calibration points and radii termination points preset on the device according to the soleplate length. The device therefore eliminates the calculation of all the calibration points and radii termination points each time an ice skate blade is to be contoured.

Abstract: The invention comprises an improved ice skate grinding, sharpening and contouring machine. The machine includes pins mounted in movable blocks to accurately center an ice skate between the heel and sole struts in a movable holding fixture and alternate eccentric pin positions to select the best contour location on the blade as a function of intended skate usage. As an example, the best blade contour for a hockey forward requires a deeper grind below the forward strut than the contour for a hockey defenseman. The centering feature assures that the skate contour desired will be accurately ground onto the blade and pitched forward the desired amount. An eccentrically mounted pin to adjust the blade position relative to the blade holding fixture for pitching is disclosed in one embodiment. In an alternative embodiment the entire fixture is pitched relative to the fixture follower rollers.

Means to adjust the blade position relative to the blade holding fixture for pitching are disclosed in one embodiment. In an alternative embodiment means for pitching the entire fixture as desired are disclosed. Figure skates can be advantageously centered and pitched as desired with the invention for accommodating the particular requirements of the figure skater.
