SKATE-DRESSING TYOOL.

Application filed August 28, 1926, Serial No. 132,212, and in Canada February 19, 1926.

Skates are generally ground upon a rotating emery wheel or the like, but the wheel is generally of comparatively coarse material and consequently the blade of the skate; is left more or less rough. My object therefore is to devise a tool by means of which this roughness may be smoothed off without danger of taking off the sharp edge which it is so desirable to retain.

I attain my object by means of the con structions hereinafter described and illustrated in the accompanying drawings in which p Fig. l is a front view of my device; and

Fig. 2 an end view of the same.

In the drawings like numerals of reference indicate corresponding parts in the different figures.

My device comprises a U-shaped frame, usually bent up from a sheet of flat metal. Between the legs 1 of the frame is positioned a spacer 2, which is usually a little less in thickness than the thickness of the skate blade to be dressed. WVrapped around this spacer is one or more plies 3 of sand paper or emery cloth. The spacer and the abrading material carried thereby are held in place by means of a bolt 4 by means of which the legs 1 are drawn together to frictiona'lly hold the spacer and abrading material in position As skate blades usually have their greatest thickness right at the lower edge, and gradually decrease in thickness towards the plates by means of which the skates are secured to the shoe, the spacer 2 will also preferably be similarly shaped.

It will be notedthat the lower edge of the spacer 2' is somewhat back from the ends of the legs 1, so that the extending ends of the legs form guides which engage the sides of the blade to prevent sidewise movement of the device. proper alinement with the blade of the skate, and there is therefore little danger of the device tilting to one side and there fore acting more on one side of the blade than the other.

The device is used by placing the same with the legs 1 straddling the blade and the abrasive material in engagement with the blade. The device is then moved back and forth longitudinally of the blade until the blade has been given the desired surface.

To" remove any burring, which may be formed on the sides of the blade, I provide The device is thus held in iabrading cloth, it will be apparent that, one

or more plies of suitable material may be wrapped around the spacer bar to give the necessary thickness to permit the skate to enter the space between the guides. I

The frame 1 will usually be made of spring material so that the legs normally tend to move apart.

The bolt 1 will be provided with a square neck, .and one of the legs 1 will be provided with a similarly shaped hole. The nut may therefore be tightened :up without danger of the bolt also turning.

lVhile the device is intended particularly as a dressing tool and not as a sharpening tool, it will of course be evident that once the blade has been well ground on a grinding wheel, it would not be difficult to keep a good edge on the blade for a considerable timeby means of my device.

From the-above description it will be seen that I have devised a construction which will satisfactorily attain the object of my invention as set out in this, specification.

It will be noted on reference to the drawing that the spacer 2 is tapered from end to end. This facilitates the taking up of any slack which might otherwise exist in that portion of the abrading material 3 which engages the skate. The abrading material and spacer are positioned with the upper edge of the spacer engaging the bolt of a U-shaped frame adapted to straddle the blade of the skate; a spacer bar between the legs of said frame, but spaced from the ends of the legs; abrading means carried by said spacing bar; and a bolt for drawing the legs towards one anotherto clamp the spacer bar and abrading means in position, the upper edge of the spacer bar being tapered longitudinally and adapted to be wedged against said bolt to tighten the abradlng means on the spacer.

2. In a skate dresslng tool for use with skates having bladesthat taper away from greatest thickness towards the bottom of the U-shaped frame; abrading means carried by said spacer bar ,and means for drawing the legs towards one another to clamp the spacer bar and abrading means in position.
