SHARPENING DEVICE.

SPECIFICATION forming part of Letters Patent No. 609,078, dated August 16, 1898. Application filed September 18, 1897. Serial No. 652,115. (No model.)

T0 all whom it may concern.'

Be it known that I, JACOB BUYER, a citizen of the United States, residing at Sandusky, in the county of Erie and State of Ohio, have invented certain new and useful Improvements in Devices for Sharpening Scissors, Knives, 85e. of which the following is a speci` iication, reference4 being had therein to the accompanying drawings.

My invention is designed to provide simpleV and efficient means for sharpening all kindsv of edged tools, such as scissors, knives, sickles, scythes, die.; and to this end my invention lconsists in the novel construction, arrangement, and combination of abrading means, all as more fully hereinafter described and shown.

In the drawings, Figure l is an elevation of the device as arranged for sharpening scissors. Fig. 2 is a plan view thereof. Fig. 3

Fig. 4 is a detached perspective view of the slide. Fig. 5 is a plan view of a modified form of abradingbar.

My device embodies the abrading means A B. The abrading means A consists of two like pieces of convex-shaped bars a d, secured together in any suitable manner, with their convex sides turned outwardly. Each of the bars is file-cut, one being right out and the other being left cut, or what is technically called one side upcut7 and the other side overcut when speaking of files cut in this manner on two sides. Each of the bars a is preferably formed of a fiat bar, which after being out is bent in the convex form and suitably tempered. The uniting of the two bars maybe done by soldering along the edges or, as shown in Fig. 5, by providing them with suitable shanks secured in a common handle O. The other abrading-surface B consists of a thin piece of extrahardened steel, which is secured to a slide formed of sheet metal in the form shown in the drawings, in which D forms a sleeve fitting the bar c., E a guide-flange, and F the holderfor the abrading means B, formed along the edge of the guide, all arranged in such manner that the sleeve D forms a slide upon the bar a and can be adj usted thereon in any desired position, while the guide-flange E forms an angle with the bar in such manner that the file-cuts thereon form with said guide an angle of about ninety degrees, more or less, the ile-cuts being of the usual angle.

In practice it will be seen that scissors may be sharpened by drawing thev blade with its bevel edge across the bar in the V-shaped angle formed between the bar and the steel blade and use the guide-iiange for guiding the blade. In this manner the bar a. will abrade the bevel or scissors edge and the steel blade B will simultaneously remove the bur left thereon. Y

For sharpening knives or other edge-tools the slide is removed and the bar A is used in the same way as a'steel or whetting-tool is used.

My device is very simple, and the abradingsurfaces may be utilized to their full extent,

Vas the slide may be reversed upon the bar d,

while the steel bladeB may be adjusted up or down or reversed in the holder F.

What I claim as my invention isl. In a device for sharpening edge-tools,

the combination of a file having its operative faces oppositely out, capable of use as a whetting-tool, and a detachable slide upon said bar carrying cutting means in inclined relation with one sideof said bar.

2. In'- a device for sharpening edge-tools, the combination of an abrading-bar and a detachable slide composed of the sleeve D, the guide-fiange E, the holder F on one edge of the guide-flange and the steel B in said holder.

3. In a device for sharpening edge-tools, the hollow double convex abrading-barA composed of two iile-cut concavo-convex bars, secured together one being cut tothe right and the other to the left.

4. In a device for sharpening edge-tools, the combination of the double convex bar A, file-cuts upon opposite sides transversely to each other and a slide thereon, composed of the sleeve D the guide-liangcE obliqueto the sleeve, the holderF and the steel B adjustably secured therein.

5. In a device for sharpening edge-tools, a hollow double convex abrading-bar composed .of two file-cut concavo-convex bars, said bars being oppositely cut, and a handle for said device also serving as a securing means for said bars, substantially as described.

6. In a device for sharpening edge-tools,

so A- IOO for securing said bars or strips together with their Convex sides outward.

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

JACOB BUYER.
