RAZOR-BLADE STROPPER;

Specification of Letters Patent. Patented Ailg. 15,1911,

Application filed November 2, 1910. Serial N 0. 590,330.

To all whom it may concern:

' of which the following is a full, clear, and

Be itknown that I, Isrnonn KL IN, a citizen of the United States, and a resident of the city of New York, Rockaway Beach,

borough of Queens, in the countyof Queens and State of New York, have invented a new and Improved Razor- Blade Stropper,

exact description.

This invention relates to. ainew and improved device for holding safety razor blades of various types during the operation of sharpening.

'An object of this invention is to provide a device which will be simple in construction, inexpensive to manufacture, strong,

I durable, and easilybperated.

A further object of this inventionis to provide a sharpener for safety razor .blades,

comprising a holder consisting of a plurality fof leaves hinged together and having profiO jections and recesses for; securing the different types of safety razor blades so that they can be readily stropped or sharpened in any suitable manner.

These and further objects,together with the construction and combination of'parts, will be more fully described hereinafter and particularly set forth in the claims.

.Reference is to be had to the accompanying drawings forming a part of this speci fication, in which similar characters of reference indicate corresponding parts in all the views, and in which- Figure 1 is a perspective view showing the device open, ready to receive a safetyrazor blade; Fig. 2 1s a horizontal longitudinal section; Fig. 3 is a section on the line 33 of Fig; 2'; Fig. 4 is a sect-ion on the line 4-4 of Fig.2; and Fig. 5 is a section on the line 5-5 of Fig. 2. g

'Referring more particularly to the separate parts, itwill be seen that this holder comprises a pair of members 1 and 2, hinged together at 3 by any suitable form of binge joint. These members are of the nature of leaves, and are adapted to be locked. to-

gether in their closed position by means of a nut 4, which engages a screw formed of two half screws 5 and 6 provided on the end of each of the leaves 1 and 2. These half screws 5 and 6, when they cometogether, forma whole screw, which will en gage -in thev screw-threaded socket on the nut 4, and therebylocl; the two leaves in their closed position. The nut .4 preferably the above description.-

conforms to the quastelliptical form of the cross section of the two leaves when closed together. While these leaves may 'be made of any suitable form and material, they are preferably stamped out of sheet metal, and 'have various projections and concavities therein, to hold various types of safety razor blades between them.

For the Gillette blade, the form of which is indicated at 7,-there are provided a plurality of projections 8, which engage in from one of the edges'of the holder as to permit the edge of the razor blade to pro;

ject beyond the latter a suflicient distance to permit the edge of the razor blade to be, sharpened.

For such safety razor blades as the Sexto-Blade, the width of which is of somewhat less magnitude, there is'provided a rec ss 11, in which fits the enlargement 12 on this type of blade, indicated at 13. This recess 11 is located at'the proper distance from the edge of the holderor sharpener, so that it will permit the edge of'the blade to pro- 7 ject a sufficient distance to be sharpened.

For such blades as the Gem, which more nearly resembles an ordinary razor in cross section, and is provided with'a considerable enlargement formed integral with the blade and extending gradually from the front edge to the back, there are provided recesses 14 in each of the leaves, so located and formed as to secure such type of blade, indicated at 15,- between the leaves of the holder, in such a position that the edge thereof will projectbeyond the holder a sufficient distance to permit the blade to be sharpened. v 0 The utility of-thedevice wlll be readily understood when taken in connection with This device can be standing that it can be used with any one ld with the under-- v 25 ing out of the sheet metal, on one side of the,

of a plurality of different types of safetyrazor blades. If the owner happens to have a Gillette razor, a blade similar to the blade 7 can be inserted between the leaves of the holder or sharpener, and the leaves secured together by the nut 4. The projections 8 will secure the blade in such a position that it will be prevented from swinging, and it will be possible to sharpen both edges of the blade without opening the sharpener.

If the Gem type of blade is used, the opposite end of the. holder or sharpener can be used to secure the blade, as indicated. in Figs. 2 and 5, and the operator then grasps the hinge end of the holder during the sharpening operation. Other types of blades can be conveniently sharpened by securing them in the depressions or cavities 1Q,and 11., It will be seen that the device can be made very cheaply from sheet-metal, by anywell- .knownstamping operation, and can be adjusted time.

It will be noted that, inasmuch as the recesses and projections are formed by stampto any type of blade in'a very short holder,.those portions of the holder which are used to retain the razor blades will be in the form of projections on one side, and on the opposite side will be in the form of cavities or recesses.

While I have shown one embodiment of my invention, I do not wish to be limited to the specific details thereof, but -desire to be protected in various changes, alterations and modifications which may come within the scope ofthe appended claims.

Having thus described my invention, I

of said leaves'having a pair of projections to secure by Letters arranged in spaced relation at one end of said holder, adapted to engage in openings in a razor blade, said leaves having depressions on their opposedfaces at the end opposite to that at which said projections are provided, adapted to receive a razor blade, said leaves also having a plurality of depressions interposed between said projections and said first-mentioned depressions, adapted to. re-

ceive other types of razor blades.

In testimonywhere'of I have signed my) nameto this specification in the presence oftwo subscribing witnesses. ISIDORE. KLEIN, Witnesses: I
