FREDERICK J. KALTEYER, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO ELECTOSTEOP MANUFACTURING COMPANY, A CORPORATION OF PENNSYL- VANIA.

BLADE HOLDER FOR SAFETY-RAZOR BLADES.

Application filed June 24, 1920. Serial No. 391,483.

T 0 all whom t may concern Be it known that I, FREDERICK J. KAL- TEYER, a citizen of the United States, residing in Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented cert-ain new and useful Improvements in Blade Holders for Safety-Razor' Blades; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same, reference being had to the accompanying drawings and to the let-` ters and figures of reference marked thereon, which form a part of this specification.

My invention relates to blade holders for safety razor blades while being honed or stropped. It has for its object to provide novel features of construction which contribute to expedition in making the holder, and result in producing a holder strong and durable in use, and in which the blade may be readily inserted and detached and effectively clamped when in the holder. To the accomplishment of the foregoing and such other objects as may hereinafter appear the invention consists in the features hereinafter particularly described and then sought to be clearly defined by the claims, reference being had to the accompanying drawing forming part hereof and in which- Figure 1 is a front elevation of part of a suitable sharpening device with the blade holder in position;

Figure 2 is a front view of the blade holder;

Figure 3 is a face view of a vblank from which one jaw and supporting prongs of the holder are found;

Figure l is a face view of a blank from which the other jaw is formed; and Figures 5 and 6 are vertical sections through the jaws fulcrums.

In the drawing the numeral 1 designates a suitable sharpening device formed with an overhanging arm 2 to which the blade holder may be clamped so as to support the blade in position to be acted on by the honing or stropping rolls 3.

The letter A designates a blank from which one jaw of the holder is made, and B the blank from which the other jaw is made. The blank from which one jaw is made is formed with a tongue which re- @elves a Spring that hQlclS @ne jaw to the other and serves also to supply the pressure for clamping a blade between the jaws, and it is also formed with fulcrum bearings on which the other jaw is fulcrumed, and also formed with studs designed to enter openings usually formed in safety blades and adapted to enter openings formed in the other Ijaw so as to center and steady the connection between the two jaws when in closed position. The blank from which the oppositejaw is made is formed with an opening to receive the spring bearing tongue of the companion jaw; also with openings to receive the fulcrum bearings of the other jaw, and with openings to receive the steadying and centering studs of the companion jaws. These several parts are subject to modification in details but the preferred construction is as follows. One jaw, designated by the numeral t, is formed with upwardly extending arms or prongs 5 by which the holder may be supported from the sharpening mechanism. It is slitted to form a tongue 6 which is bent at an angle to the plane of the jaw and is formed with an opening 7 which has laterally extending slots 8. The opening 7 is designed for the insertion of the legs or prongs 9 of a spring 10 having coils 11 and a loop 12, the legs or prongs of the spring spreading apart after insertion through opening 7 and entering the lateral slots 8 the walls of which serve as bearings for the legs or prongs so as to hold the other jaw against which the loop of the spring bears in closed relation to its companion jaw under spring tension, the upper ends of the legs or prongs being bent into hook form and seated in perforations 13 formed in the jaw. The jaw l is further slitted to form fulcrum bearings 14 bent at an angle to the plane of the jaw and upon which is mounted the other jaw 15 which is formed with openings 16 to receive the bearings 14 upon which the jaw 15 fulcrums. Thej aw 4; is also formed with bosses or studs 17, preferably made by pressing out a portion of the metal of the jaw, which are designed to enter openings usually formed in safety blades, such as blade 18, so as to center the blade between the two jaws, and the companion jaw 15 is formed with openings 19 which may receive the studs 17 as illustrated in Figure 2 and thus serve to steady the connection between the parte when the jaws are in their @10Std post tion. The upper portion of the jaw 15 lis bent at an angle to the plane of the jawA so as to form a finger grip 2O by which the jaw-15 may be manipulated for the insertion and withdrawal of the blade from between the jaws, and isA also formed with an opening 21 registering with the coils of spring 10 for the passage of the .prongs .of the spring and to straddle the tongue 6 when the jaw is swung open. When the jaws are formed and connected one to the other by means substantially such as described, a very efficient holder for blades in the operation of sharpening is produced; appropriate r bearings for the connecting parts affording stability and firmness of bearing points is assured; and strength and durability and simplicity in use of the holder obtained.

Instead of forming the fulcrum bearings so as to projectfroni jaw 4 they may be formed to project from jaw 15 as shown in Figure 6' but the functioning of such parts is the same in both forms and therefore same reference numerals are used.

I have described with particularity the preferred details of the various parts but changes can be made therein and essential features of the invention retained.

Having described my invention and set forth its merits what I claim is:

1. A blade holder for sharpening devices comprising oppositely disposed jaws, one jaw having a tongue formed with an opening having elongated extensions and with projected fulcrum bearings, and the other jaw formed with openings to receive said bearings for fulcruining one jaw on the other, and a spring connecting the two jaws, one part of said spring bearing against one jaw and having-prongs bearing in the elongated slot extensions of the tongue of the companion jaw.

2. A blade holder for sharpening devices comprising oppositely disposed jaws, one jaw having a tongue formed with an elongated opening and with projected fulcruin bearings and the other jaw formed with openings to receive said bearings for lfulcruniing one jaw on the other, and a spring connecting the two jaws, one part of said jaw having a tongue formed with an opening, and also with projected fulcrurn bearings, and the other jaw formed with openiings to receive said bearings for fulcrurning one jaw onthe other, and a spring connecting the' two jaws, one part of said spring bearing against one jaw and having prongs bearing in the elongated opening of the tongue of the companion jaw and having their ends seated in perforations in the jaw.

4.-. A blade holder forsharpening devices comprising oppositely disposed jaws, one jaw having a tongue formed with an opening and also with projected fulcrum bearings, and the other jaw formed with openingsto receive said bearings for fulcruming one jaw on lthe other, vone jaw also being formed with centering bosses and the other with corresponding openings therefor, and a spring connecting'the two 'jaws,jone part of said spring bearing against one jaw and another part bearing in the tongue of the companion jaw. j

5. A blade holder for ,sharpening devices comprising oppositely disposed jaws, one jaw having projected fulcrum bearings and the other openings to receive'said bearings for fulcruming one jaw on the other, with the fulcruming point close to the adjacent faces of the two jaws, and having itsV upper portion deflected at an angle to the plane of the jaw to constitute a finger grip for manipulating the aw, and a spring connecting the two jaws, one part of said spring bearing against one jaw and another part having a bearing in the companion jaw.

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