Embodiment Construction

[0020] Referring therefore to FIGS. 1 and 2, a portable skate sharpening device is generally denoted by numeral 10. The device 10 generally comprises a relatively smooth table top surface 12 with an upstanding wall or trunnion 14 attached at a rear edge of the surface 12, and a rotatable grinding device 16. The device 16 is supported such that its lower portion protrudes downwardly through an aperture 60 in the surface 12 when positioned in the configuration shown in FIG. 1. The grinding device 16 has a body 18, a guard 20 attached to the top of the body 18, and an actuating system 24 attached to the right wall of the body 18. The body 18 is attached to a plate 40 which is slidable relative to the trunnion 14

[0021] As best shown in FIG. 4, the grinding device 16 is pivotally attached to the trunnion 14 with a pin 100 and a threaded stud (not shown). The pin 100 is preferably supported by the trunnion 14 with a bearing 105. The threaded stud protrudes through an arcuate slot 102 in t...

Abstract

A skate sharpening device is provided which allows a grinding device to rotate with respect to a working surface of the device in both a cross grind configuration and a finish grind configuration. The grinding device pivots about a pin and is guided by a threaded stud protruding through an arcuate slot and securable using a flared, hand operated nut. A slidable rack attached to the grinding device is moveable in fore and aft directions relative thereto. A dressing tool may be attached to the rack and its forward position is governed by an actuating system. The actuating system allows a user to selectively inhibit forward movement of the rack to position the dressing tool at a suitable position to allow a dressing bit to contact a grinding wheel attached to and powered by the grinding device to dress the grinding wheel.

Description

[0001] This application claims priority from U.S. Provisional Patent Application No. 60 / 653,610 filed Feb. 16, 2005.FIELD OF THE INVENTION [0002] The present invention relates to skate sharpening devices. DESCRIPTION OF THE PRIOR ART [0003] The use of a grinding wheel for sharpening ice skates is well known. There exists numerous machines which utilize a motor-driven grinding wheel supported on a table top or other working surface for sharpening skates. To sharpen an ice-skate, an operator of the machine typically advances the blade of the skate towards the rotating grinding wheel making contact with the wheel to create a concave surface on the blade's ice engaging surface, commonly known in the art as a “hollow”. The hollow provides a pair of relatively sharp edges at terminal ends of the resulting concave surface. [0004] In some cases, a skate will be sharpened by first cross grinding the blade to remove the old edge. A cross grind is performed by passing the bottom of the blade a...
