A skate blade sharpening device having a housing that includes a top wall, side walls and a bottom wall that form a hollow chamber. The top wall has a lid separated by a front face and a back face. The front face extends from a first edge to the lid and the back face extends from a back edge to the lid. A groove extends from the front edge to the back edge along the bottom wall. Disposed within the hollow chamber of the housing is a motor, at least one battery, a grinding wheel, at least one magnet, a dust catching compartment, and a micro-computer.

A skate blade sharpening system used to sharpen the blades of ice skates. The skate sharpener can include a housing that includes an elongated slot for receiving the blade of an ice skate for sharpening, and clamp jaws for retaining the skate. The housing can include at least one slot cover to engage the skate blade. Engagement of the skate blade can be sensed by a controller to enable sharpening operations to proceed. The skate blade sharpening system can automatically operate a grinding wheel and move the rotating grinding wheel back and forth along the lower face of the skate blade a desired number of times to sharpen the skate blade.

The present disclosure provides for a skate sharpening system comprising an operative unit and a base, the operative unit comprising a central body, the central body comprising a skate receiving slot, a skate clamp being positioned adjacent to the skate receiving slot such that a skate can be secured within the skate receiving slot for a sharpening operation, the operative unit further comprising a grinding unit, the grinding unit being configured to translate along a length of the slot such that the grinding unit can conduct the sharpening operation on the skate that is secured within the skate receiving slot, the operative unit being positioned over at least a portion of the base, the base comprising a swarf-receiving cavity, the operative unit and the base being pivotably connected.

A skate sharpening system comprises an adjustor assembly and a skate holder assembly. A runner is releasably coupled to a template runner, and then clamped into the skate holder assembly. The template runner defines a pre-defined profile for the blank runner. An operator moves the skate holder assembly such that the template runner moves along a guide bearing of the adjustor assembly. The guide bearing is disposed proximate a grinding wheel. While the template runner remains in contact with the adjustable guide bearing, the runner remains in contact with, and moves along, the grinding wheel such that the grinding wheel simultaneously sharpens and contours the runner.

The invention relates to apparatus for polishing a running base that comprises a blade with two opposing blade edges separated one from the other by an intermediate section; the polishing apparatus comprising: a support body, and blade alignment guide means; wherein the support body is capable of carrying a polishing surface which comprises: a profile which is adapted to conform with one or more portions of the intermediate section; and wherein the blade alignment guide means comprise one or more pairs of first and second blade alignment guides, which first and second blade alignment guides in each pair are separated from each other by the polishing surface, and further wherein the blade alignment guide means is adapted to receive and/or guide and/or constrain a running base so that when the intermediate section between the two edges of the running base is brought into contact with the polishing surface, there is no contact between the polishing surface and any part of the two opposing blade edges of the running base.

In at least one embodiment, the present invention discloses a manual blade sharpening tool having a longitudinally extending at least partial channel defined by a longitudinally extending first channel wall, a cutter pocket and a distal planar guide surface located in the longitudinally extending first channel wall, and a longitudinally extending cutter having a longitudinally extending first cutter wall, a longitudinally extending second cutter wall and a transverse cutter surface, the transverse cutter received in the cutter pocket such that one of the longitudinally extending first cutter wall and the longitudinally extending second cutter wall abuts the cutter pocket.

The method is for profiling blades with a belt grinding profiling machine. The blades are mounted into a vise. A vertical position of the template is adjusted by rotating the rotatable knob. The motor is turned on to rotate the grinding belt over the grinding wheel. The guide wheel engages the underside profile of the template. The guide wheel of the template guides movement of the grinding wheel mounted on the common axle by moving the guide wheel along the underside profile of the template. The grinding belt grinds material off the underside of the blade until a portion of the underside profile of the template is copied to the underside of the blade.

An automated self-service machine for the selective sharpening of ice skate blades utilizes a pair of actuating mechanisms that operate a sharpening device. The sharpening device is disposed within a base and accessible only when activated. A user wearing the ice skate blade to be sharpened steps onto the base and inserts the ice skate blade within a slot where the sharpening blade resides. A control system is configured to enable a user to interface with it to provide the activation of the sharpening device and to enable financial transactions.

Computer-implemented method of operating an ice skate blade grinding apparatus, which comprises determining a number of contiguous ice skate blades inserted into the apparatus; and setting an operating parameter of the apparatus based at least in part on the determined number of contiguous ice skate blades. This allows optimized sharpening and profiling of multiple blades at a time.

A blade for a skate for skating on ice. The blade includes ice-contacting material with an ice-contacting surface for contacting the ice. The ice-contacting surface has a machined longitudinal profile with a radius of curvature that varies smoothly over a majority of the length of the blade. Such a radius of curvature may, in some cases, be an elliptical arc.
