PARKER SAFETY RAZOR Filed Nov. 28, 1930 2 Sheets-Sheet 2 Patented Sept. 15, 1931 UNITED -s'lze'ras PATENT ,y OFFICE A RILEY HEEBEE-T rAExEE, or NORTH MASSAcHUSETTs, AssieNoE To GILLETTE SAFETY EAzoE coMrANY, or BosToN, MASSACHUSETTS, AconPoEATIoN OF DELAWARE SAFETY RAZOR Application led November 28, 1930.l Serial '110. 498,788.

This invention relates to safety razors and relates more particularly to a umversal holder for safety razor blades. 4

An object of the invention is to provide a '.6 safet razor in which either a iexible blade or a rigid blade can be used.

There are two t pes of safet razors now enerally employed. One type, own as the illette type, utilizes a transversely flexible l blade having op osed longitudinal cutting edges, the blades eing flexed between the cap and uard members of its holder to place the shaving edges in their proper position relative the guard.- The other type of safety razor utilizes a non-flexible blade having only one shaving edge.

According to this invention, a safety razor i-s rovided with which any of the commercia -safety razor blades now available' canA be 3 used. The ossessor of a safet razor, ac-

cording to this invention, is thus ree from the necessit of keeping an7 particular make or type of lade i'n stock, a l lades being equally usable.

- 95 In o'ne embodiment ofthe invention, an

ordinary type guard and handle is employed with a novel form of ca The cap as its inner. face adapted to ex a blade placed between it and the guard member, as is done in the ordinary Gillette type razor, and is provided also "with a longitudinal aperture parallel and s aced behind one of its longitudinal sides t rough which the shaving edge of a non-iiexible lade can be introduced, the blade being clamped upon the guard by the longitudinal edge ,portion of the cap.

e The invention can be embodied in various forms, the preferred form herein described being one in which all of the parts of the holder are constructed as in the ordinary Gillette type razor with the exce tion of the cap piece, the Alatter beign there ore capable of use in substitution for the cap piece of a Gillettetype razor, constituting an article of manufacture.

' A preferred embodiment of the invention will now be described with reference tothe drawings, of which:

Fig. 1 is a-side'view of an assembled razor e 5 according .tolthis invention;

prevented from further movement by the ex- Fig. 2 is a plan view looking down on the razor of Fig. 1' 4 A Fig. 3 is a plan view of a cap piece of the safety razor Shown by Figs. 1 and 2;

Fig. 4 is a side viewshowing a non-Hex'ible blade inserted in the safety razor according to this invention;

Fig. 5 vis a side -view partially'in section of the razor shown by Fig. 4, and* Fig. 6 is a artial View of the razor assembled with a exible blade.

The safety razor illustrated comprises the guard piece 10, the lower portion 11 of which serves as a part of the handle of the razor. The guard 10 has the central aperture 12 which serves to `receive the threaded stu'd 13 of the cap piece-14. The handle portion 11 of the guard IO-has the central aperture 15 which serves to receive; the threaded ortion 16 -of the adjustable handle portion 1 The threaded. ortion 16 of the'handle screws onto l the threa ed stud 13 of the cap piece 14and upon rotation of the portion 17 of the handle, i

the cap piece 14 andthe guard 10 are positioned together. The cap piece 14 is provided with the longitudinal aperture 18 'extending parallel to and behind the longitudinal edgeportion 19 of the cap piece. The longitudinal edge portion 19 is provided with the two extensions 20 which extend beyond the edge of and adjacent the ends of the longitudinal edge portion 19.

Figs. 1, 2, 3, 4 and 5 illustrate the safety razor of this invention utilizing a non-flexible. blade. The cap 14 and the guard 10 are first assembled before the blade is inserted. Then before the cap piece 14 and the guard 10 are clamped tightly together, the non-flexible blade 21 is placed, as shown by Figs. 4 and 5, through the longitudinal aperture 18 in the cap piece 14. The blade 21 is passed through the aperture 18 until the edge portion 22 of the blade strikes against and is tensions 20 of the cap piece 14. The cap piece 14 and the guard 10 are then clamped to' gether by adjustment vof the handle portion Y 17, the4 portion of the blade-21 just to the rear of the cutting edge 22 being clamped in po 100 sition in contact with, the guard 10 and the edge portion 19 of the cap piece 14.

The non-flexible blade 21 can be easily inserted and easily removed from the safety razor and serves just as satisfactorily in this type of holder as in a holder designed solely for a non-flexible blade.

The holder illustrated may be used also with a transversely flexible razor blade, `this type of blade being shown clamped between the cap piece 14 andthe guard 10 of the razor in Fig. 6 of the drawings. The flexible blade 23 is first assembled on the cap piece 14, the cap piece being provided with the lade positioning studs 24 which fit in the positioning apertures (not shown) in the blade. The cap member 14 and the positioned blade are then assembled onto the guard 10. The blade is flexedinto position by the clamping action of the cap piece 14 and the guard 10 on tightening of the handle portion 17 (shown by Fig. 5). The one shaving edgev 25 of the flexible blade 23 is contacted with by the guard 10 and the longitudinal edge 26 of the cap piece 14, this longitudinal edge 26 being similar to that used in the ordinary type Gillette razors. The other shaving edge of the blade 23 is in contact with the edge portion 19 of the cap piece 14 which with a flexible blade acts to flex the blade in exactly the same way as the normal edge 26 does. The

edge portions

19 and 26 of the cap piece 14 are so arranged that they flex their respective sides of a transversely flexible blade the same amount, the two

edge portions

19 and 26 having the same length, being spaced the same distances from the center of the cappieee 14, and being arranged to position the shaving edges of the blade the same, relative the guard 10 of the razor..

As before stated, the handle and guard portions of an ordinary Gillette type safety razor can be employed with the novel form of cap piece described to enable both nonflexible and flexible blades to be utilized with easy facility in the one razor. When a nonflexible blade is used, the edge portion 26 ofthe cap piece 14 is not utilized, the razor inthis instance havin a single shaving edge. When a transversely flexible two edged blade is used, both of the longitudinal portions of the cap piece are used, the two edges of the blade belng e ually available for shaving, except that sma l portions of one of the edges of the flexible blade are guarded by means of the extensions 20.

Whereas one embodiment of the invention has been described for the purpose of illustration, it should be understood that the invention is notlimited to the exact details described as many departures may be made by those'skilled in theart without departing from the spirit ofthe invention.
