UNITED STATES PATENT trion IIEBBERT VW, B. GOXVDY, OF UNION PIER, MICHIGAN.

SKATE-SHARPENER.

SPECIFICATION forming part of Letters Patent No. 59'7,163, dated January 11, 1898. Application filed Aprl 1, 1897. Serial Ne. 630315. (Nomodai To all whom it may oonoern:

Be it known that I, HERBERT XV. B. GOWDY, a citizen of the United States, residingat Union Pier, in the County of Berrien and State of Michigan, have invented certain new and useful Inprovements in Skate-Sharpeners; and I do herehy declare the following to be a full, clear,'and exactdescription of the invention, su eh as will enable others skilled iii the art to which it appertains to make and use the same.

My invention appertains to skate-sharpeners, and relates more particularly to a device adapted for holding a section or piece of file, preferably having a flat and convex side.

My improved sharpener consists in the construction and combination of parts, as will be hereinafter fully described and claimed, reference being had to the accompanying drawings, in which- Figure 1 is a top plan View of my invention complete, showing the members thereof ad- Fig.` 2 is an end elevation showing the file so adjusted as to present its convex face. Fig. 3 is a similar View showing the file a'djusted to present its fiat face. Fig. i is a central longitudinal section of Fig. 1.

For convenience of reference to the various details involved they will be indicated by figures, the same figure being applied to the, same part throughout the several views.

Briefly stated, my invention may be said to consist in providing a holder which is laterally adjnstable, enabling the jaws thereof to accommodate varying widths of runners, and also of certain accessories deemed necessary to hold the parts in their adjusted positions Referrng to the drawings, l and 2 represent the holding members of my skate-sharpener. Said members consist of the jaws proper, 3, designed to lie upon either side of the skate-runner, receivin g the same between them. The upper ends of said members term'i-nate in the lateral bend or head i and 5, respectively, the head 4 being provided upon its upper surface with the recess 6, having the end guideways 7, while the head 5 is provided with the laterally-extending flange or body 8, designed to be received by the recess 6 and held therein by the guideways 7. (More clearly shown in Figs. 1 and l.)

In order that the j aws may be held in an adjusted position with respect to each other, I provide the set-screw 9, which is seated in a threaded apertnre provided in the recess 6 after first passing through the slotted opening 10, centrally fol-med in the fiange S. By this arrangement it will be readily apparent that the jaws may be separated or drawn together and held in the desired position by simply turning home said set-screw.

The holding` members 1 and 2, it will be observed, are also provided upon their inner faces with the offset or open section 11, designed to provide a seat 173 for the file 13, and in order that said file may always be held in its seat in such position that the plane thereof will be parallel With the edge of the jaws I locate upon one end of each of the seats 12 the guide-block 14, preferably formed integrally with the jaws, the inner face of which is inclined upwardly and inwardly, as more clearly shown in Fig. 4. By this construction it will be readily apparent that said guide will always direct the end of the file downward, no matter what the thickness thereof may be, thus holding the same in position to receive the bottom edge of the shate-runner as it is placed between the jaws.

Upon the end of member 2 I locate the bracket or lip 15, preferably integrally formed with said member. Mounted in a suitablythreaded aperture in said bracket I locate the thumb-screw 16, designed to take entirely through said bracket and engage with the free end of the file, and as said screw is directed inwardly the action thereof will be to force the file inward and also lock it securely in position upon the seats 12, preventing any lateral or longitudinal movement.

It will of course be un derstood that the parts forming my improved skate-sharpener maybe construoted of any preferred and suitable material, though it is thought that best results will follow when a low grade of cast metal is employed, rendering it possible to cheaply and expeditiously produce the de- Vice.

The operation of my improved skate-sharpener may be stated to be as follows: After the parts are assembled in their respective operative positions and a section of a file placed IOO 2 &7,163

upon the seats 12 the adjusting-screw 9 is loosened, when the jaws may be separated sufficiently to loosely receive between them the runner of the skate, when said screw is turned home in its seat, thus binding the parts firmly together. The thumb-screw 16 is then turned tightly against the end of the file, when the sharpener may be appled to the skate-runner by simply reciprocating the same thereon until the desired result is produced, enabling the device to beefiectively used by any one, even though not skilled in the work.

lt will of course be understood that if a face which shall be at right angles to the walls of the runner isdesired the fiat surface of' the file will be exposed. If, however, it is desired that the bottom of the runner shall present a coneave face, of course the convex side of the file will be presented.

It Will be seen from the foregoing that I have produced a simple, cheap, and efficient skate-sharpener, and believing the Construction and operation thereofwill be fully apparent furtherreference is deemed unneces sai-y.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. A skate-sharpener consisting of adjustable jaws, one jaw having a groove in each end, and the other jaw fitting said groove, and means to fasten the jaws, as set forth.

2. A skate-sharpener consisting of adjust able jaws, one having a depressed portion on its top surface, and the other jaw sliding in able jaws, having a tongue-and-groove joint,

and means to hold the jaws in any desired position, as set forth.

5. A skate-sharpener consisting of adjustable tongu eand-grooved j aws having depending parallel 'extensions to receive the runner of a skate, and` a file carried on the upper shoulders of the extensions, and means to hold the file in place, as set forth.

6. A skate-slarpener conssting ofadjustable jaws, each j aw having a triangular guideblock at one end,`and means to force a file against said block and hold it in place, as set forth.

7. A skate-sharpener consisting of adjustable jaws having a tongueandgroove joint, one of the jaws having a longitudnal extension carrying a set-screw adapted to press against a file and hold it in place, as set forth.

In testimony whereof I afix my signature in presence `of two witnesses.
