  • Self-centering skate holder
    Patent number: 7473164
    Abstract: A self-centering skate holder for clamping a skate blade from above and below which maintains the blade at a predetermined height and parallelism. A handle is connected with a cable which is taut and extends around the circumference of the upstanding vertical member. The movements of the cable activate cam levers which rotate cams that move a pair of jaws towards or away from each other. The simultaneous movements of the cams ensure that the jaws move in unison and through a similar distance allowing a skate blade of any thickness to be clamped along the desired centerline. In an alternative mechanism, a tie bar extends between the jaws and is operated by a cam to induce equal and opposite movement of the jaws.
