To all whom 'it may concern:

Be it known that I, HARRY DLFLO, of Philadelphia, in the county of Philadelphia and StateA of Pennsylvania, have invented certain new and useful Improvements in Razor-Blade Holders, whereof the following is a specification, reference being had to the accompanying drawings.

My improvements relate to blade holders emplo ed for the purpose of stropping replaceable razor blades, and it is the object of my invention to construct a strong, cheap and durableblade holder which is capable of receiving and firmly holding all forms of replaceable razor blades in order that they may be stropped therein.

In the accompanying drawings, Figure I, is a side view of my blade holder. Fig. II, is a front view thereof. Figs. III, and IV, are cross sections along the line III, III, in the preceding figures, differing in the shape of the contained blade. v

My blade holder is adapted for use in connection with either the old fashioned triangular blade, or the thin blade with permanent backing, or the ordinary thin blades, whether single or double edged, as employed in Amany safety razors; and for this purpose comprises a holder in the elastic jaws adapted to contain the blade, but permitting adjustment, in combination with a pivoted clamp by which the jaws of the holder are so firmly clamped as to prevent motion of the blade therebetween.

My device is formed of a single piece of sheet metal folded along its median line and cut along its edges so as to form a combined handle and holder of the shape illustrated. It will thus be observed upon reference to Figs. I, and II'that from this single piece of bent sheet metal is formed the handle 1, the stem 2, and the holder proper 3. The article is nar-rowest in the region of the stem and here the free edges of the sheet may be turned in so as to prevent their exposure.

The holder 3, comprises the back 4, the sides 5, 5, and the jaws 6, 6. The sides 5, 5, are spaced a suicient distance apart lto permit the reception between Vthem of the head of an ordinary triangular razor blade. The jaws approach more closely together, being separated by only a narrow slot, through which the thin part of the blade projects and between which it is clamped. The metal ksides are exible, and therefore operate to compress the jaws under spring pressure upon the thin portion of the blade but this spring ressure is not of itself suflicient to rmly old the blade during stropping, but serves to vinitiall hold it during its pro er adjustment within the holder. To ren er this spring lpressure the more elastic,

the sides are lerced by elongated slots 8, e,

This clamp is pivoted to the holder by a pivot 18, passing through the stem 2. The distance between the sides of the clamp is such that when it is forced down upon the back of the holder, as seen in full lines in Fig. I, it compresses and binds thefsides, and therefore the jaws of the blade holder together, with a pressure which is much greater and much more unyielding than that lmparted to the jaws by the elasticity of the osides of the holder.

My blade holder is ca able of use as I have explained with di ering sizes of replaceable; razor blades, the sides being spaced to admit of the reception of either a triangular blade, as'shown in Fi IV, or a thin blade with permanent hacking as shown in Fig. III. In operation these blades are inserted by the user between the jaws of the holder, while the clam ing piece is turned back. The elasticity o the jaws temporarily holds the blade in the position shown in Figs. III, or IV, until the clamp is swun forward and forced into the position in Pig. I, where it grasps and clamps the sides of the holder, under which circumstances the jaws are so tightly pressed as to prohibit any possible movement of the blade during the stropping operation. In addition to thus holding blades of this sort, my blade holder is adapted to any of the thin blades, some of which are double edged, which are used with various styles of safety razors. Such blades are inserted in the holder substantially as shown in Fig. III, except that where a double edged blade is ing it in the holder, that the inner edge, if

already sharpened, be not dulled by contact with the ,back of the holder, and this is rendered easy in my construction of blade holder, because the jaws of the holder are so spaced as to prevent free motion of the blade between them, and by means of the visibility of the inner edge of the blade through the slots 8 8, there is no difficulty in placin the blade in its proper position between t e jaws, with its inserted edge free from the back of the holder, and then moving forward the clamp to firmly clamp the jaws without further motion of the blade with respect to the jaws.

Having thus described my invention, I claim i l. A razor holder comprising handle, exible sides, back connecting said sides, and opposed jaws formed integrally of a single piece of metal, in combinatlon with a clamping piece pivoted to the holder and capable of embracing its sides at a point adjacent receive the back of a triangular razor blade,

and pierced by-slotted apertures; jaws eX- tending from the sides and spaced so as to clamp the thin ortion of a razor blade between them, an a clamping piece by which additional pressure may be put upon the sides and therefore upon the jaws.

3. In a blade holder provided with springpressed blade-holding jaws, a clamping piece capable of embracing the holder and putting additional pressure on the jaws, :11nd comprising a back, sides, and pivoting u s. v

In testimony whereof, I have hereunto si ned my name, at Philadelphia, Pennsy vania, this eleventh day of October, 1909.

HARRY DIFLO.
