SAFETY-RAZOR.

Specification of or NEW Yoann. Y.

Leers raient. Patented Feb. 17, 1914.

Application filed November 26, 1913. Serial No. 803,263.

To all whom it may concern i B6 it kIlOWn that I, GUS MAJOR` KAISER,l a citizen of the United States, residing at New Yorkcity, in the county of New York and State of New York, have invented new and useful Improvements in 'Safetyl-azors, of which the following is a specification.

The eneral object of this invention is to refine tie construction of safety razors, in point of promoting the efficiency of the same and in cheapness of manufacture. And to these ends the invention resides-in a flat, relatively rigid blade and a resilient shield adapted to be adjusted in relation tothe edges of the blade.

Other objects will appear and be better understood from that embodiment of my invention of which the following is a specification, reference being had to the accompanying drawings forming part hereof, in which:

Figure 1 is a perspective view of my improved razor. Fig. 2 is a side view of the razor partly in elevation and partly in sec-- tion. Fig. 3' is a dissected perspective view 'of the elements forming the razor.

The razor,as shown in the drawings, con' sists of theC holder 5 and the blade (5. The holder 5 is formed of a plurality of members which include the handle 7 the guard 8 and the blade retaining member 9.

r1`he blade 6 used in my improved razor is formed from a flat and relatively rigid sheet of razor-steel, and While it is of sufficient thinness to admit of a minimum expense in manufacture, it is substantially rigid for all purposes of shaving. In order that it may be especially adapted to be used in my improved razor-holder, which will be hereinafter-fully described, a centrally disposed perforation 10 is provided in the blade; and so that the life of the blade may be douj bled, the usual double shaving-edge 11-11 is provided. p

The blade is carried, when in the holder 5, by the retainer 9, which may be made of cast steel or any like material. While the inside length of the retainer 9 and the length of the blade are of the same dimensions, the Width of the retainer is narrowed so that the edges of the blade may project beyond the edges of the retainer. A substantially long stem 12 is centrally positioned on theJ inner face of the retainer and over this is adapted to tit the perforation 10 of the blade, As only one stem is used,

. it Would seem obvious that the blade would have angular lateral movement and to prevent this, the corners are provided with retaining lugs 13, which Contact with the opposite short ends of the blade and x the blade in a steady position. It willbe seen that the retainer is provided at each end with recesses or cut-away portions la which admit of iingerro'om when positioning the blade or removin the same from the holder.

Vhen the bla e is positionedon the retainer 9 and fitted within the side lugs 13-,13, the-shield S is placed over theblade. This shield .is substantially U-shaped and is preferably formed of light spring metal. The sides of the shield are fiared outwardly and the edges are preferably fluted as at 15, so as to provide guards for the edges of the blade and recesses for the material removed from the face during the operation of shaving. An opening 1G is centrallylocated in the top of the shield so that the stem 12 of the retainer may project therethrough. The handle 7 is provided with a screwthreaded bore 17, which is adapted to be screw-threaded over the head 18 of the stud 1Q. It will be noted that this head is relatively short and as only a portion of the bore 17 is screw-threaded, the handle can be readily placedover the stem and a few turns will suiice to secure the parts together. As shown in Fig. 2, the lower portion A19 of the handle is narrowed so as to provide a shoulder 20. The part 19 is adapted to be inserted in the opening 1G and the shoulder 2() will bear against the top of the shield; obviously, as the handle 7 Yis turned so as to tighten the parts, the shield will be under pressure and the fresult will be, that the guard ends 15 Will tend to separate, and reduce the cutting edges of the blade. Conversely, when it is desired to increase the cutting edges, the pressure on the shield is reduced. It will be seen by referring to Figs. 1 and 3 that the guards 15 are relatively longer than the sides of the shield and provide, thereby, ears 21; it will also be noted that one edge 22 of the lugs 13 is oblique and is provided with a notch 23. Now, the normal lateral distance between the ears 21 is less than the lateral distance between the remote edges ofthe vlugs 13, and upon the shield being positioned on the blade, the action of the oblique edges will be to spread the vsides of the shield apart, This spreading increases until' the llO ears 21 reach the notches 23 in the lugs, whereupon the shield will be sprung into position and by virtue of the tension in the shield, the guards 15, bearing I' the blade against the retaining member 9, Will securely hold the blade in a relatively rigid manner.

It is obvious that those skilled in the art may vary the details of construction and arrangements of parts Without departing from the spirit of my invention, and therefore I do not wish to be limited to such features except as may be required by the claim. v

Whatis claimed as new is:

In a razor, the combination with a at blade, of a blade retaining member having oppositely disposed lugs positioned at the ends thereof, the said luvs having oblique sides provided With notces, and a resilient shield provided with laterally-extending guards having ears loca-ted at opposite ends7 the said ears being adapted to be sprung over the oblique sides of the lugs and into the notches upon the shield being placed in Contact with the blade.

In testimony whereof I aiix my signature in presence of two'witnesses.

GUS MAJOR KAISER.
