1 Claim.

The object of this invention is to provide an exceedingly simple and inexpensive device by the use of which a pair of scissors or shears, which has become dull through use, may be readily sharpened by an unskilled person. The invention is illustrated in the accompanying drawing and consists in certain novel features which will be hereinafter first fully described and then more particularly defined in the appended claim.

In the drawing,

Figure 1 is a perspective view of a scissors sharpener embodying our invention, and

Figure 2 is an enlarged detail section on the line 2-2 of Figure 1.

In carrying out the invention, there is provided a holder which may be readily stamped or bent from a single unitary blank of sheet metal and formed to provide a handle I, a gage or guide 2 and a base plate 3. The guide 2 extends from the handle portion of the device at an angle thereto, as shown most clearly in Figure 2, and the base 3 is extended from the lower edge of the backing or guide plate 2 at an angle corresponding to the bevel given the cutting edge of a scissors blade. The base plate is connected with the guide or backing plate through an offset bend 4 which defines a groove or transverse recess receiving one edge of a file 5, the walls of the recess being preferably disposed at right angles to each other and so spaced as to firmly grip the edge of the file so that it will be securely held. Between the ends of the outer edge of the base plate, there is formed a tongue 6 which engages around the outer edge of the file, as clearly shown, so that the file will be fixed in the holder and will not be dislodged while in use.

When the device is to be used, the blade to be sharpened, indicated at "I, is placed against the backing or guide plate 2 with the beveled edge of the blade resting on the file immediately at the lower edge of the guide plate, as clearly shown in Figure 2. The sharpener is then moved along the edge of the blade from end to end of the same, or the blade may be reciprocated over the file, sufficient pressure being exerted to maintain the file in contact with the blade and remove irregularities in the blade so that the desired cutting bevel will be quickly restored.

It will be noted upon reference to Figure 2 that the file is double-faced so that when one face of the file has been worn smooth, through long continned use, the file may be removed from the holder and reversed and then re-inserted. It will also be noted that the blade bears upon the file adjacent one edge thereof only and the wear will be,

of course, upon only a small portion of the surface of the file. When the file has been worn smooth along one edge or adjacent an edge it may be slipped endwise from the holder and then turned so that the edge which was previously outermost will be engaged in the groove 4 and pre 11) sent a new working face for engagement with a scissors blade. It is very desirable to provide the groove 4 inasmuch as the edge of the file is thereby firmly gripped and also the blade will be in contact with the face of the file through the en 15 tire cutting edge of the blade whereas, if the file merely rested against the face of the backing plate, the edge of the blade immediately adjacent the backing or guide plate might be out of engagement with the file and would not be properly sharpened. It will be understood upon reference to Figure 2 that the base plate is disposed at such an angle to the backing or guide plate that when the blade is resting on the file with its side against the backing plate and its edge on the file it will be held at the proper angle to produce the desired efficient bevel of the cutting edge.

The device is exceedingly simple and may be produced at a trifling cost while it is eificient in use and may be manipulated by any person however unskilled mechanically.

Having thus described our invention, we claim:

A scissors sharpener comprising a unitary holder consisting of a strip of sheet metal bent intermediate its length to form a flat end portion constituting a handle and a guide extending downwardly from the front end of the handle, the strip being then bent to form a lip extending rearwardly from the lower edge of the guide and then bent downwardly and forwardly to form a flange and a base member projecting forwardly from the flange beyond the guide and having a pocket along its rear side formed by the lip and flange, a tongue extending upwardly from the front side edge of the base member and overha nging the same, and a file resting upon the upper 45 face of the base member with its rear edge portion engaged in the pocket and its front edge portion overlapped by the tongue.
