COMBINED SAFETY RAZOR AND BLADE SHARPENER.

Application filed April 13, 1925. Serial No. 22,652.

My invention relates to improvements in combined safety razors and blade Sharpeners, and has for its primary object a device which can be used either as a safety razor or as a device to hold the blades while being sharpened and stropped.

A further object is to construct a combined safety razor and blade sharpener in which a double edged blade is designed to be held and which is provided with a pivoted and rotating shield by means of which either edge of the blade can be protected during the stropping, and which is provided with a removable guard, which can be readily placed in position when it is desired to use the device as a razor.

In the drawings Fig. 1 is a plan view of my device showing a blade therein and illustrating the manner of swinging the shield away from the blade by dotted lines. Fig. 2 is a cross section taken on the line 2-2 of Fig. 1 and illustrating the manner of stropping one side of the blade.

ig. 3 is a longitudinal section of the handle taken on the line 3-3 of Fig. 1 and showing the device with the shield removed.

Fig. 4 is a perspective view of the shield.

Fig. 5 is a perspective view of the swivel for the shield. i

Fig. 6 is a side elevation of my device when arranged as a razor.

Fig. 7 is a front view of the same with part of the handle broken away; and

Fig. 8 is a top plan view of the guard.

In the construction of my device, I employ a handle 9 which is preferably hollow as illustrated in Fig. 3, and which has its open end closed by means of a plug or knob 10. The opposite end of the handle is provided with a screw threaded lug 11, which is designed to be secured in the screw threaded socket 12 formed in the blade holder. The blade holder is provided with the end 13 in which a screw threaded socket is formed and also with a groove 14 in which the swivel 15 is located. This swivel is formed of a piece of sheet metal bent in the form of a circle and is provided with perforated cars 16. The forward portion of the blade holder is flattened so as to be substantially elliptical in shape and is composed of two members 17. These members are spaced apart and have secured therebetween strips of cork or similar material 18. The purpose of the cork it to tightly grip the blade and prevent the same from slipping. Pivotally secured to the cars 16 are cars 19, which are formed integral with the shield. The shield is substantially U shaped in cross section and has its one face provided with slots 20; the purpose of these slots will be explained in detail later. The free edge of the shield is slightly rounded as at 21 so that it will pass partially over the portions '17 of the blade holder. Adjacent the curved portion 21 are longitudinally extending depressions 22, which are also for the purpose of coming in contact with the portions 17 and preventing the shield from being pushed forward and contacting with the edge of the blade. It is to be understood, of course, that the shield is formed of spring material and be stiff enough so that the stropping will not force the shield ut of the position illustrated in Fig. 2.

When it is desired to use my device as a razor the handle 9 is unscrewed from the screw threaded socket 12 and secured in a boss 23, which is provided with a screw threaded socket. Secured to the boss 23 is a guard which is substantially U shaped in cross section and which is designed to be slipped over the shield. The portion 24 of the guard is solid as illustrated in Fig. 8

and is provided on its forward edge with a plurality of spaced apart teeth 25. These teeth are for the purpose of preventing the person shaving from cutting himself. The remaining portion of the guard is composed of strips 26, which are of a width to fit in the slots 20 and thus prevent any possibility of the guard shifting while in use. The forward edges 27 of these strips are'designed to bear against the blade 28 and to prevent any springing of the edge of the blade when the device is in use. This guard is also made of spring material so that it can be easily attached and detached.

When it is desired to strop a razor blade, the shield is swung into position indicated by dotted lines in Fig. 1, the blade then inserted between the cork filler 18 and securely held therein by means of the members 17, which are formed of spring material so that they will give slightly. After the blade has been thus secured properly in position the shield is swung into position indicated by solid lines in Fig. 1 and the device is ready for stropping or honing. The blade can now .be handled like an ordinary razor blade,

' the shield is being held with the other, thus bringing the sharpened edge in position to be covered by the shield. The other edge of the blade can now be sharpened in the same manner.

When it is desired to use the device as a razor the guard 24: is placed in posit-ion, the handle 9'unscrewed from the blade holder and screwed into the boss 23. Should it be found desirable, the guard can be moved forward or back, thus regulating the degree of closeness of the shave.

It will be seen from the foregoing that with my device a double edged blade can be stropped with the same motion now emloyed in stropping the old fashioned razor lade, there being absolutely no possibility when turning .the blade for reversing the stroke of cutting the strop as is the case where both edges of the blade are exposed.

Having fully described my invention, What I claim is I 1.
