SAFETY-RAZOR STROPPER.

Specification of Letters Patent.
Patented N ov. 21, 1916a Application'led Apr120, 1916. Serial No. 92,393.
To all whom it may concern:
Be it known that l, BERNHARD TRosKY, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Safety-Razor Stropper, of which the following is a full, clear, and exact description. Y
This invention relates to a stropping device for razor blades of the double edge type, and deals particularly with means for holding the blade in'coperative relation with the rollers or sharpening elements.
The invention has for its general objects to improve the construction of devices of the character referred to so as to, be reliable and elicient in use, comparatively simple and inexpensive to manufacture, andis so designed that the blade is automatically clamped or unclamped in closing or opening the casing.
A more specific object of the invention is the provision of 'a stropping device of that vtype embodying a pair of rollers or stropping elements mounted in the body of the casing and between which is a stationary bar forming art of the razor blade holder, and on the lid of the casing is resliently mounted the other part of the holder, so that the two parts coperate to grip the blade and hold it firmly in cooperative relation with the rollers or sharpening elements.
With such objects in view, and others which will appear as the description proceeds, the invention comprises various .novel features of construction and arrangement of parts which .will be set forth with particularity in the following description and claims appended hereto.
In the accompanying drawing, which illustrates one embodiment of the invention and wherein similar characters of reference indicate corresponding parts in all the views, Figure 1 is a perspective view of theO device with the lid of the casing open;
Figs. 2 and 3 are vertical sectional views respectively on the lines 2 2 and 3 3, Fig. l; and Fig. 4 is a section yon the'line 4--4 Fig. 3.
Referrin to the drawing, 1 designates the body ofY the casing or box and 2 the lid or cover which is hingedly connected at 3 with the body, the cover and body being so proportioned that the device can be conveniently gripped in one hand while the stropping or sharpening elements may be operated by the other hand, which turns the operating crank 1. Fastened in the casing is a frame consisting of end plates 5 and 6 which are connected together by a central cross-bar 7 integrally united with the top edges of the'plates 5 and 6. These end plates support parallel shafts 8 and 9, the latter of which extends through the front wall of the body 1 and carries the operating crank l. The shafts have fastened thereto sharpening or stropping elements 10 and 11 respectively, and they also have gears 12 and 13 which are connected together for simultaneous rotation by inter-v meshing pinions 14.
The razor blade holder is formed in part by the bar 7 and by a complementary bar 15 carried by the cover on ,the inner face thereof. One of the bars, for instance, the bar 7, has lugs 16 which are adapted to engage in apertures 17 of the bar 15. These lugs are adapted to engage in the usual apertures 18 of the razor blade 19 which is clamped between the two bars 7 and 15 in such a position that the edges of the blade will be in tangential relation to the rotary stropping elements 10 and 11. These elements operate only on one side of the blade at a time, so that it is necessary to' l reverse the blade in order to strop both sides. The blade-holding bar 15 is resiliently mounted on the cover, and-for this purpose the bar is made of a strip of spring metal which has its ends of Z-sliape, as
shown in Figsfl. and 4, so that the portions 2O will be springs and the portions 21 bases that are riveted or otherwise secured tol the cover. By making the blade roller partly on the cover and partly on the body of the casingvthe blade is automatically*clamped or unclamped by the closing or opening of the cover.'v y
From the foregoing description taken in connection with the accompanying drawing, the advantages of. the cnstruction and method of operation will be readily understood by those skilled in the art to which the invention appertains, and while I have described the principle of operation, to-` gether with the device which l now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made when desired as fall within the scope of the appended claims.
By yieldingly mounting the member 15, the razor'blade is yieldingly clamped in pm sition, so that the edges can yield when the leather or stropping surface contacts therewith. It is difficult to obtain on the market a leather which is of uniform thickness, so that the leather on one roller might be higher than the leather on the other roller, and consequently the clasping of the attaching one of the bars toits associated sectionof the box and permittin the har to yield when a blade is clampe 'between the bars by the bringing 'ofthe box sec` tions together.
' 2. A. razor sharpening device comprising a .casing composed of two sections movable .ff i with respect to each other, sharpening .35 posed of two registering bars, and springs means in the casing, and a blade holder comsupporting one of the bars and serving to conneetlsuoh bar with one of the sections of the casing d y '3. A razor sharpening device comprising a body, sharpeningmeans mounted therein,
a bar on the body and disposed tohold al razor blade in coperative relation with the said means, a cover hingedly mounted on the body, a bar carried by the cover and adapted to mate with the first-mentioned bar to clamp the razor blade on -the latter, said lastfmentioned bar having Z-shaped extremities ,rigidly secured tothe inside of the cover, whereby the second-mentioned bar is resilient.
BERNHARD TRosKY.
