rrnn STATES ATnN'r COMBINED SKATE SHARPENER AND GROOVER.

SPECIFICATION forming part of Letters Patent No. 641,752, dated January 23, 1900.

Application led September 9,1899. Serial No.730,009. (No model.)

To a/ZZ whom it may concern.-

Beit known that 1, ALBERT A. STEPZINSKI, acitizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented a new and useful Oombined Skate Sharpener and Groover, of which the following is a specification.

My invention relates to skate-Sharpeners; and the object thereof is to provide a device of the character described whereby the file can be interchangeable to make a concave groove or a plain surface, the edges of which are sharp, on the runner of the skate.

With this object in view my invention con sists of a plate having depending side flanges andin the center of which is secured alongitudinally-arranged ille and supplemental plates secured on the side flanges and carrying inwardly-projecting arms to which are journaled guidingrollers, whereby the runner is guided in contact with the cutting-surface of the ille.

My invention further consists of certain parts and combinations of parts, all of which will be described in detail hereinafter, recited in the claims, and illustrated in the drawings, in which-u Figure 1 is a perspective view of a skatesharpener constructed in accordance with my invention. Fig. 2 is a longitudinal section through the same. Fig. 3 is a bottom View, and Fig. 4 is a transverse section through the line 4 t of Fig. 3.

Referring now to the drawings by referencenumerals, 5 indicates the casing, consisting of a plate 6, provided with depending

side flanges

7 and 8, and 9 is a front flange depending from the plate 6 and connecting the

flanges

7 and 8 at its ends.

10 is a handle secured to the rear portion of the plate 6, the object of which will be apparent and which will be referred to hereinafter.

11 is a file or abradiug tool oval in crosssection and provid ed at its rear end with rightangular openings 12 and 13, respectively. The other end of this le is bifurcated, the projections 14 and 14: projecting through openings 15 in the front flange and the projections 16 and '16a lying snugly against the bottom edge of the flange 9. .A pin 17 projects through suitable openings in the side anges and through one of the openings 12 or 13 to securely hold the le in place.

The

supplemental plates

18 and 19 project slightly above the plate 6 and are adjusted to and from the side flanges by a threaded pin 19a.

Four sets of parallel arms 2O project through the side llanges, and journaled between the file ends of said arms are guide-rollers 21, preferably in the form of a truncated cone. These arms and rollers are properly spaced apart and are positioned slightly below the file and can be adj usted to and away from the longitudinal center of the file by the pin 19a to accommodate dierent widths of runners.

The ille is shown in position to abrade the longitudinal edge of the skate, so that the edge thereof will be sharpened; but by removing the same and turning it so that the reverse side of le will be presented to the skate-runner a concave groove will be made. In this instance the projections 16 and 16a would project through the opening in the end flange 9 and the

projections

14 and 14 would lie against the bottom edge of said flange.

The operation of my device is as follows: The runner of the skate is secured between the guide-rollers by adjusting the supplemental plates through the medium of the threaded pin when the skate is rested upon a suitable support, the handle grasped by the operator, and the whole device reciprocated, thus making a clean even groove.

- While I have shown and described a particular style of file, it is obvious that any style might be employed, and I reserve the right to use a tool having only one cutting edge or a plurality, if desired.

Having thus fully described my invention, what I claim as new, and desire to obtain by Letters Patent of the United States, is`

1. In a skate-Sharpener, the combination'- arranged in said casing, inwardly-projecting arms extending through said flanges and IOO adapted to secure the skate-runner in operatieally-journaled rollers carried by the free tive connection with the file, substantially as ends of said arms adapted to guide the skatedescribed. runner against the cutting-surface of the file,

3. In :t skate-Sharpener, the combination substantially as described.
