RAZOR-BLADE HAODER AND STROPPING DEVICE.

Application led December 9, 1920. Serial No. 429,430.

T ov all whom z't'may concern Be it known that I, HARRY OJHAs'rINGs; a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain -new and useful Im rovements in Razor- Blade Holders and Stropping Devices, of which the following 'is a specification'.

rlhis invention relates to a holder for safety razor blades for use during the procam aware, of course, that holders for said purpose have previously been provided but, 1n the present invention, the holder is so constructed as to be capable of retaining either single or double edged blades without slipping.

And furthermore, the holder is provided with a coverof such a nature that, during.

the process of stropping the blade, a rela-l tively small portion of such cover is evenly deposited over the surface of the strop and acts as an abrasive whereby 'a very line edge isV imparted to the blade.

rllhis invention also provides an especially light but strong holder whichis particularly inexpensive to' manufacture in view of' the fact that it consists of but a single strip of material, convex in cross section, and bent double so that the doubled end provides the jaws between which a blade may be held and the free ends cooperate topform a. round handle over which-a locking device slides4 for firmly clamping the blades in xed position between the jaws. f

In the drawings, wherein there is shown a specificA embodiment of the invention on a somewhat enlarged scale for clearly showing details:

Figure 1 is a vention in use;

'Figure 2 is a longitudinal ,section inta vertical plane;

y Figure 3 is asectional 3-3 of Figure 2;

Figure 4 is a sectional view on the line of Figure 2; Figure 5 isa view similar to Figure-3 but showin blade c amped therein;

view on the line Figure' 6 is a perspective view of a hold-v clip for a double edged blade; igure 7 is a view similar to Figures'3 perspective view of the inthe holder with a doubleedgedV i and 5 bu-t showing the holding clip of Figure 6 in use.

In detail: t

The invention comprises a holder A having the handle portion l and the jaw portion 2 which-latter, as will be hereinafter set forth, is adapted to grip and hold safety razor blades of the type indicated by B and C in Figures 3 and 5 of the drawings.

The holder is formed of metal throughout and the body portion thereof which is shaped tov provide the handle portion 1 of cylindrical cross section and jaws 2 consists of a length of metal, such as pressed steel or the like having a natural spring, is convex in cross section and is beaded as shown at 3 'so that the saidbeads lie opposite each other when the length of metal is doubled, as at 4.

However, previous to .doubling the metal body there is applied thereto, between the beads 3, a piece of sheet lead as indicated at 5` and the edges 6 of which are curled over the edges of the convex metal body. The metal body is then doubled, as previously mentioned, to bring the beads 3 opposite to each other where they serve to define the leaded jaw portion .2 from the handle portion 1 and also act as a stop for a clamping member to be later mentioned. The two sides thus formed are slightlytsprung apart at the beads 3, as clearly shown in F1 and the free ends 'are fastened together by a ferrule 7, after a slidable clamping ring .l

clamped between the jaws but in this case.

the back edge of the blade may rest agamst the inside edges of the jaws opposlte to those actually clamping the blade.

It is of course obvious that various grades of lead may bev ein loyed for the jaws de'- f pending upon the ubricating andk abrasive properties, but in any event the liolders cornprise a still' metal body portion forming a foundation for the flexible lead facing of the jaws.

In order to provide for sharpening one p edge at a time of a` double blade, a clip such as is shownn Figure 6 may be used. This clip is made of light spring metal and comprises the base portion 9 and jaws 10 and 11 having the curled edges- 12 and 13 respectively. In using the clip, the double edged blade is inserted in the position shown in Figure 7 in the clip whiclris then inserted in the holder with the curled edges 12 and 13 resting against the holder. L'

Each edge of the double edged blade may be thenstrop'ped in the' usual manner incident to the single edge blade. Y

ll claim:

l.1 In a razor blade lholder and stropping j device, a pair of spring jaws for receiving and clamping .the blade, and an abrasivel carried by said jaws for deposit on the razor strop.

2. ln a razor. blade holder and stroping device, a pair of spring jaws faced with lead for clamping-the blade frictionallytherebetween, means for contracting the said Yjaws into clamping position, and a handle.

3. ln a razor blade holder and stro'pping device, a metal bar doubled to provide jaws and a handle, a lead facing for said jaws,

end neans for contracting said jaws tc clalnl a'blade therebetween.

l. n ay razor blade holder and stroppin device,l a metal bar doubled longitudinally and sprung apart intermediate its ends to provide jaws and a handle, a lead facing for said jaws7 and means carried by said handle for contracting the jaws.

lln testimony whereof ll aflix my signature.
