Definitions

  • Another object of the invention is to provide ice skate sharpening equipment by means of which repeated sharpening of blades to maintain their predetermined longitudinal contour can be accomplished with minimal loss of blade stock.
  • the invention consists in a novel series of steps, conveniently practiced by usage of the illustrative embodiment herein disclosed, for intermediate shaping of a skate blade as well as the ultimate sharpening of its ice-contacting contour.
  • FIG. 1 is a plan view, with portions broken away, of an ice skate sharpening device, its follower means being indicated in three selected operating positions relative to a fixed contour cam; 7
  • FIG. 3 is a plan view corresponding to FIG. 1 but on a smaller scale and showing successive positions of the work holder and follower means as the blade is sharpened;
  • FIG. 4 is a schematic plan view, the curvature being exaggerated, and showing three different ice tangency points of a longitudinally radiused blade and corresponding to its initial longitudinal indexing;
  • FIG. 5 is a detail view in vertical section of a portion of a grinding wheel and indicating the transverse blade curvature imparted thereby;
  • FIG. 6 is a perspective view of an alternative work holder arrangement by means of which longitudinal indexing of a blade may be selected relative to the blade clamp template followers of a sharpening device;
  • FIG. 7 is a plan view, partly in section, of indexing means for a tubular blade.
  • FIG. 8 is a section taken on the line VIII-VIII of FIG. 7.
  • a horizontal work support is provided on which a work holder comprising a carriage 20 is horizontally movable, for example on its legs 22 two of which are shown in FIG. 2.
  • the carriage 20 is formed with opposed, parallel guide ways 24, 24 for receiving a slide 26 an upstanding portion 28 of which is fitted at its upper end with spaced blade positioning pins 30, 30 defining a line extending normal to the guide ways 24, 24.
  • Hinged to the top of the portion 28 is a clamping plate 32 for securing a blade 34 of a skate generally designated 36 to be sharpened.
  • a locking means shown in the form of a threaded stud 38 projecting from the portion 28 and through a bore in the plate 32 may receive a wing nut 40 to hold the blade in clamping relation with the slide 26.
  • the pins 30, 30 may be removed and an alternative clamping plate 39 mounted in the same manner as the plate 32 is engageable with a longia flange 41 of its tube portion.
  • the carriage is provided with a pair of spaced elements such as follower rolls 44, 44 (FIGS. 1-3, inclusive).
  • the rolls 44 are journalled in a holder 46 pivotally mounted on and slidable along a horizontal fulcrum pin 48 having end bearings in the carriage 20.
  • An edge portion of the holder 46 is formed between the rolls 44 with at leastone and preferably several teeth 50 which, when the rolls are lowered to horizontal operative dash line position shown in FIG. 2, mesh with correspondingly shaped indexing teeth 52 (FIG.
  • each skater by prick punch or other marking, permanent or temporary, on his blades 34 or skate register a point or identification of position that he desires his ice tangency to correspond with an index mark of the scale 58.
  • he can always sharpen his skates by duplicating the desired contour in the edge 42 and removing a minimum of blade stock. He can by resort to this same skate sharpening mechanism in any geographical area restore the desired blade contour and point of ice tangency or shift it in predictable manner.
  • an adjusting screw 60 threadedly extends through a bore of a lug 62 formed on the slide 26, and has an inner end secured against relative axial movement by a set screw 64 in a lug 66 on the carriage 20.
  • the lug 66 slidably extends in a slot 68 parallel with the guide ways 24, 24. Accordingly, rotation of a knurled knob 70 affixed on the screw 60 shifts the slide 26 parallel to the guideways and the skate clamped on the slide is moved in a radial direction toward and from the grinding locality of the wheel 12.
  • FIG. 6 An alternate longitudinal indexing mechanism is shown wherein it is assumed the follower rolls 44 (one shown) have their axes fixed in the carriage 20.
  • FIG. 6 construction corresponding parts are identified by the same reference characters heretofore employed.
  • the blade clamp 32 is now provided with a mounting block 72 rabbetted to slide longitudinally of a skate blade on a mating tongue 74 formed on the slide 26. Registry as desired of a scale 76 on the block 70 with a reference mark 78 on the slide 26 is obtained by turning a knob 80 of an adjusting screw 82 extending through an end of the tongue 74 and threaded into the block 72.
  • a suitable wheel 12 may be substituted.
  • 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.
  • 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.
  • 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.
  • 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.
