ICE SKATE SHARPENING DEVICE

摘要

a lightweight transversely pivoting and longitudinally sliding skate carriage exhibiting exceptionally low friction, introduces a high degree of sensitivity into the process of skate sharpening, facilitating very light grinding cuts and low uniform traversing speeds, enabling a relatively unskilled operator to product superlative surface finishes and accurately maintain the blade "rocker" profile. The carriage pivotal axis is so located and the skate blade so positioned that the "hollow grind" is accurately centralized throughout the length of the blade. The low friction, pivotal provision enables the blade to be held in sensitive contact with the cutting wheel controlling the depth of cut, whilst the longitudinal sliding provision permits sensitive control of rate of cutting lengthwise along the skate blade. The skate carriage is readily removeable and being lightweight facilitates inspection of the blade surface during the course of sharpening, it may be fitted with rolling elements to accommodate both the pivotal and longitudinal motions. The longitudinal profile or rocker of the blade may be controlled by mounting a template to the carriage parallel to the longitudinal axis, which engages a stationary roller throughout the course of longitudinal travel, thereby replicating the template profile onto the blade during the sharpening operation.
