SKATE RUNNER SHARPENER Filed April 15, 1947 INVENTOR. D n 6y L.6/ocum Patented Oct. 7, 1947 I ve r iiariiemn unces for 1 1579? blades of ice skates of'the "type having a "holderfora sharpening gstone,
wherein the holdermapbe hldin one'hand'and slid the other hand, and inparticular, a substantially C-shaped clamp in which a grinding stone may be clamped against an open side or slot, and the width of the slot adapted to be adjusted to provide a snug fit over'the blade or runner of the skate. I
The purpose of this; invention is to provide a holder for grinding stones, wherein the stone may readily be actuated for sliding contact with an ice-contacting edge -of an ice skate runner for sharpening the runner.
Various devices have-been provided for holding sharpeningstones for ice skates and other purposes, but to maintain a smooth cutting or grinding surface, it is essential to incorporate means for readily changing the position of the stone, and at the same tim means for rigidly holding the stone in operative position. With this thought in mind, this invention contemplates a device having a skate runner-receiving slot with means adjusting thewidth thereof and means clamping a grinding or sharpening element in relation to the slot so that the element is positioned to engage the ice-contacting edge of a skat runner held in'the slot.
The object of this invention is, therefore, to provide a clamping element having an ice skate runner-receiving slot in one side in which means is provided for clamping a sharpening element against the inner end of the slot.
Another object of the invention is to provide a holder for sharpening elements of ice skate runners, wherein a skate runner is inserted in a slot therein for sharpening, in which means is provided for adjusting the width of the slot to compensate for skate runners of different thicknesses.
A further object of the invention is to provide a unique, manually actuated sharpener for ice skate runners having a combination of clamping elements therein which is of a simple and economical construction.
With these and other objects in view, the invention embodies a substantially rectangular,
c-shaped frame with a continuous skate runnerreceiving slot in one side, a thumb screw extending into the side in which the slot is positioned from one end for adjusting the width of the slot, a grinding stone positioned in the frame, and a aloi'i'ga skat rufifier, with the skate held in thumb screw for-clamping t-he' grin ding' stone in operativeposition. I
Other featuresand advantages offthe invention will appear from the following description, taken in connection with-thedrawings;wherein:
Figure l is a view showing a front elevation of the sharpener.
Figure 2 is a view showing an end elevation of the sharpener.
Figure 3 is a view illustrating the operative position of the sharpener as it would appear in use on the runner of an ice skate with the runner indicated in dot-and-dash lines.
Referring now to the drawings, wherein like reference characters indicate corresponding parts, the ice skate runner sharpener of this invention includes a rectangularly-shaped frame having vertically disposed end members [0 and H with their upper ends connected by a horizontally disposed side l2 and with inwardly extending sections 13 and M at their lower ends. With the parts arranged in this manner, a slot l5 xtends continuously through the lower side and a skate runner l6, as indicated in dotted lines in Figure 3, may be positioned in the slot. The width of the slot may be adjusted by a thumb screw I! that is threaded through the section 14 and provided with a disc l8 at the inner end which contacts a side surface of the skate runner.
A cylindrically-shaped sharpening stone I9 is positioned in the frame with the lower surface thereof covering the inner end of the slot l5 so that as the blade or runner of the skate is placed in the slot, the ice-contacting edge thereof wil contact the lower surface of the stone.
The stone i9 is clamped in the position shown in Figure 1 by a thumb screw 20 threaded through the upper horizontal side l2 and the inner end of the thumb screw is provided with a clamping element or disc 2|.
With the elements arranged in this manner, the stone [9 is clamped in the holder with the lower surface positioned at the inner edge of the slot [5 and with the holder placed over a skate runner, as illustrated in Figure 3, it may be actuated with a reciprocating movement backward and forward on the runner, wherein the stone will sharpen the runner. Th position of the disc I 8 may readily be adjusted by the thumb screw I! to compensate for runners of difierent thicknesses, and as the stone is used, the position thereof may be continuousl changed by loosening the thumb screw 20 so that grooves will not be-worn in the under surface thereof.
It will be understood that modifications may be made in the design and arrangement of parts without departing from the spirit of the invention.
What is claimed is:
1. A holder for ice skate runner-sharpening stones comprising a substantially C-shaped'frame having vertically and horizontally disposed webs with an open longitudinally extending slot positioned in one side intermediate the ends thereof, a thumb screw threaded in the side opposite to that in which the slot is positioned, and a centrally disposed thumb screw threaded through one end of the side in which the slot is positioned for adjustably contacting the adjacent side of a skate runner positioned in the slot.
2. A holder for ice skate runner-sharpening stones comprising a substantially C-shaped frame having vertically and horizontally disposed webs with an open longitudinally extending slot posi-' tioned in one side intermediate the ends thereof, acylindrically-shaped sharpening element positioned in the frame over the inner end of the slot, a thumb screw threaded in the side opposite to' that in which the slot is positioned for clamping the sharpening element against the inner 4 H surface of the side in which the slot is positioned,- and a centrally disposed thumb screw threaded through one end of the side in which the slot is positioned for adjustably contacting the adjacent side of a skate runner positioned in the slot.
3. A holder for ice skate runner-sharpening stones comprising a substantially c-shaped frame having vertically and horizontally disposed webs with an open longitudinally extending slot positioned in one side intermediate -,the,,ends thereof,
a cylindrically-shaped sharpening" element posi-.
tioned in the frame over the inner end of the slot, a thumb screw threaded in the side opposite to that in which the slot is positioned for clamping the sharpening element against the inner surface of the side in which the slot is positioned, a disc rotatably mounted on the inner end of the thumb screw, a centrally disposed thumb screw threaded through one end of the side in which the slot is positioned for adjustably contacting the adjacent side of a skate runnerpositioned in the slot, and a contacting element rotatably mounted on the inner end of said centrally disposed thumb screw.
