BLADE SHARPENING DEVICE FOR ICE SKATES Filed March 2, 1935 -1nu|:n[nr Joseph U102 21 I %%%Z/ Patented June 2, 1936 ATENT OFFICE BLADE SHAREENING DEVICE FOR ICE SKATES Joseph Viozzi, Hamilton, Ontario, Canada, as-
signor to Vitz Skate Hone Company, Hamilton,
Ontario, Canada Application March 2,
1 Claim.
My invention relates to improvements in blade sharpening devices for ice skates, and the object of my invention is to provide a small device which the skater can carry in his pocket, and which comprises a skate blade engaging stone adapted to be rubbed along the blade in engagement with the edge thereof and positioned between a pair of metal guide members which engage and slide along the sides of the blade.
A further object of my invention is to secure the guide members and contained stone together, by means of one or more screws passing through the guide members and which are of sufficient length to permit stones of various thicknesses to be used in the one device.
My invention consists of such a sharpening device constructed and arranged all as hereinafter more particularly described and illustrated in the accompanying drawing in which:
Figure 1 is a perspective view of an ice skate blade, showing my device being applied thereto.
Figure 2 is an enlarged side elevational view of my device.
Figure 3 is an end elevational View of my de vice showing it applied to a skate blade.
Figure 4 is a side elevational view of the inside face of one of the guide members and also showing the stone positioned thereon.
Figure 5 is a side elevational view of an alternative form of my device wherein the device permits both the upper and lower edges of the stone being used.
Figure 6 is an end elevational view of the device shown in Figure 5, and Figure '7 is a side elevational view of my device,
in reduced size, showing the use of a single centrally positioned guide plate joining screw.
Like characters of reference indicate corresponding parts in the different views in the draw- My device primarily consists of an abrasive sharpening stone made from suitable material and having one or more of its edges of transverse convex form designed to put the proper concave edge on the blade of a skate, together with a pair of guide plates positioned one on each side of the stone and extending beyond the cutting edges of the stone to lie along the sides of the skate blade.
In my device as illustrated in Figures 1 to 4, the guide members comprise a. pair of rectangular plates 1 and 2 having their lower edges bent outwardly to form lips 3. A fiat substantially rectangular abrasive stone 4 is positioned between the upper parts of the two plates and the as- 1935, Serial No. 9,042
sembly is secured together by a pair of screws 5. The screws are freely contained in counter-sunk orifices in one plate, as the orifices 6 in the plate I, and threaded into orifices in the other plate, as the orifices I in the plate 2.
The stone 4 has its lower edge 8 of convex cross section, and in Figure 3 it is shown applied to the concave edge 9 of a skate blade 10, as is also shown in Figure 1. The stone 4 as shown in Figure 4 has its ends H cut away in conformity with the screw holes, and its upper edge l2 can be also made of convex form so that the stone can be reversed in the plates and such convex edge l2 used. Upon reference to Figures 3 and 4 it will be seen that I form a pair of longitudinal grooves I3 in the inner faces of the plates l and 2 along the sides of the stone edge 8. These grooves are furnished to catch the abrasive material which wears ofi' the stone and which might otherwise spoil the concavity of the skate blade.
In my device as shown in Figures 5 and 6, I show a pair of plates [4 with the stone positioned intermediately of their width so that both edges [5 and Hi can be used. In this case the stone can be made of two grades of abrasive material, the material in the portion I! being coarse, and the material in the portion [8 fine. The stone as shown in dotted lines in Figure 5 can be of rectangular form and of less length than the distance between the screws I9.
The sharpening device shown in Figure 7 is substantially the same type as shown in Figures 5 and 6, with the exception that the screw 20 passes through the center of the plate 2| and also through the square stone 22. four edges of the stone can be used.
To sharpen a skate blade, my sharpening device is rubbed up and down the blade in the position illustrated in Figures 1 and 3, and as the edge of the stone is convex, a concave edge will be cut in the blade. The stone used in my device is of substantially the same thickness as the blade, so that the blade is a close fit between the plates to obviate rocking of the stone on the blade. As skate blades are made in several thicknesses it will be necessary to provide the merchant selling my device with stones of such several thicknesses. In making a sale, it will be only necessary for the merchant to insert a stone of the required thickness between the plates and tighten up the screws.
Although I have illustrated and described a particular embodiment of my invention, it is to be understood that I can make such changes and alterations as I may deem necessary without de- In this device the parting from the spirit of my invention as set edge of the stone. to form a skate blade receiving forth in the appended claim. slot, means extending between the plates for What I claim as my invention is: clamping the plates and stone in assembly, and A skate blade sharpening device comprising a. lips turned outwardly from the bottom edges of flat sharpening stone positioned to engage a skate the plates below the blade-engaging edge of the 5 blade along one edge of the stone, a pair of guide stone to form thumb and finger rests positioned plates of greater width than the stone and posibelow the edge of an engaged skate blade.
