Skate sharpening devices

Claim 2

An ice skate sharpening device comprising a grinding tool operative in a fixed position, means for supporting a guide cam in predetermined relation to the tool, a carriage having follower means mounted for progressive engagement with the cam, a skate blade clamp adjustably mounted on the carriage for movement along an axis extending toward and away from an operating locality of the tool, and means for indexing relative to the follower means in a direction normal to said axis a skate blade fixedly held by the clamp.

Claim 3

A device as in claim 1 wherein the skate blade clamp is supported on a slide arranged in parallel guide ways in the carriage and extending substantially normal to the longitudinal guide face of the cam, and the follower means is laterally shiftable with respect to the slide and provided with indexing means for selectively registering therewith in a direction normal to the guide ways.

Claim 4

A device as in claim 2 wherein the follower means is a pair of spaced rollers, and a holder therefor having at least one tooth meshable with teeth arranged on the slide.

Claim 7

A work holder for causing a grinding tool and an arcuate template mounted in fixed relationship to impose the shape of the template in a selected one of a plurality of different positions on the work, said work holder comprising an independently movable carriage formed with a guideway, follower means adjustabLy mounted on the carriage and arranged to progressively engage the arcuate surface of the template, a slide adjustably movable in the carriage guideway and provided with means for clamping the work, and mechanism for selectively indexing the work held by the clamping means relative to the follower means to predeterminedly establish the selected position of the template shape in the work.

Claim 8

A work holder for causing a grinding tool and an arcuate template mounted in fixed relationship to impose the shape of the template in a selected one of a plurality of different positions on the work, said work holder comprising an independently movable carriage formed with a guideway, follower means adjustabLy mounted on the carriage and arranged to progressively engage the arcuate surface of the template, a slide adjustably movable in the carriage guideway and provided with means for clamping the work, and mechanism for selectively indexing the work held by the clamping means relative to the follower means to predeterminedly establish the selected position of the template shape in the work.

Claim 9

A work holder as in claim 5 wherein said means for clamping the work is adapted to secure a blade of a skate to be sharpened and includes a stop for abutting a work strut supporting the blade, and said slide is adjustable in the carriage guideway in directions extending toward and from said arcuate surface.

Claim 10

A skate sharpening device for use with a grinding wheel having a fixed axis and an arcuate template mounted in predetermined relation thereto, said device comprising a carriage freely movable in a plane and having follower means progressively engageable with the template at spaced points, skate blade clamping means constrained for adjustable movement on the carriage in a direction extending toward and from the template, and means associated with the blade clamping means for registering a blade clamped thereon longitudinally thereof relative to said follower means whereby a predetermined curvature derived from the template may be ground on the blade in a selected longitudinal position.

Claim 11

A skate sharpening device for use with a grinding wheel having a fixed axis and an arcuate template mounted in predetermined relation thereto, said device comprising a carriage freely movable in a plane and having follower means progressively engageable with the template at spaced points, skate blade clamping means constrained for adjustable movement on the carriage in a direction extending toward and from the template, and means associated with the blade clamping means for registering a blade clamped thereon longitudinally thereof relative to said follower means whereby a predetermined curvature derived from the template may be ground on the blade in a selected longitudinal position.

Claim 12

For use with a grinding wheel rotatable about a fixed axis and a template formed with an arcuate guide surface and mounted in predetermined relation thereto, a skate blade holder comprising a carriage mounted for independent movement, a pair of spaced follower elements mounted on the carriage for progressive contact with the guide surface of said template during carriage movement, means for jointly adjusting the points of contact of the elements along said guide surface to shift the point of ice tangency of a skate blade secured to said holder and to be sharpened by said wheel, and blade clamping mechanism mounted on the carriage and movable thereon in a direction normal to a line tangent to the follower elements, said clamping mechanism including an abutment adapted to engage a strut of the skate blade to index the blade longitudinally relative to the follower elements.

Claim 13

For use with a grinding wheel rotatable about a fixed axis and a template formed with an arcuate guide surface and mounted in predetermined relation thereto, a skate blade holder comprising a carriage mounted for independent movement, a pair of spaced follower elements mounted on the carriage for progressive contact with the guide surface of said template during carriage movement, means for jointly adjusting the points of contact of the elements along said guide surface to shift the point of ice tangency of a skate blade secured to said holder and to be sharpened by said wheel, and blade clamping mechanism mounted on the carriage and movable thereon in a direction normal to a line tangent to the follower elements, said clamping mechanism including an abutment adapted to engage a strut of the skate blade to index the blade longitudinally relative to the follower elements.
