A coEroEATIoN or NEW JERSEY COMBINED SAFETY RZVOR AND SHARPENING DEVICE Applcatonledlllay 21, 1931. Serial No. 538,936.

This invention relates to improvements in combined safety razors and sharpening devices.

Among the objects of this invention are the provision of improved means facilitating the honing or stropping of opposite faces of the edge of a single edged razor blade, or the opposite faces of the edges of a double edged razor blade without dismounting the razor lo blade from the razor. Y 1

Another object of this invention is the provision of means for holding therazor blade assembled with an outer clampingcap.

Another object of this invention is the arrangement of the improved combination of means facilitating the honing or stropping ofboth faces of an edge ofa razor blade,'at an angle with respect to the handle so that the razor blade will assume the proper angular shaving position with respect to the handle.

Another object of this invention is the provision of means forv holding a sharpening means in a position in which it does not interfere with the shaving operation. I

Another object of this invention is the provision of means for holding a sharpening means in the positions it'occupies when em# ployed to hone or strop opposite faces vof an edge of the razor blade.

Other objectsof the invention will appear from the following description taken Vin con- Anection with the drawings, in which Fig. 1 is a longitudinal section through the handle and transversely of the sharpen- 35 ing means, guard, razor blade and clamping plate, with the razor blade in shaving position and the sharpening means in position 4to sharpen hone or strop the lowerv or'rear face of one edgeof the razor blade;` A

Fig. 2 is a similar section with the outer clamping member and razor blade lifted, shown in the process of being turned toreverse the edges of the blade with respect to the guard and sharpeningV means;

Fig. 3 shows the sharpening means in pov sition to hone or strop the upper face of an edge of a razor blade f Fig. 4 is a top plan view of the device of Fig. 2; A

Fig..5 is a view of a device similar to that partly in section,

of Fig. 1 but-showing provision for flexing the razor blade and also means for supporting the sharpening rollerfso that it may be swung into position to hone or rstrop each y face of an edge of the blade; 55

F ig. 6 is a cross section on the line 6-6 Fig. 6; Fig. 8 illustrates another modified form 60 showing the razor head vdisposed at anangle to thehandle; and I I f Fig. 9 is a section on the line 9-9'of Fig. 8. fThe embodiment shown in Figs. 1, 2, 3 and 4 comprises a hollow handle 10v which at its upper end carries a guard member 11 Whichhas a substantially strai ht outer face', on one side edge of which are Y ormed curved guard lingers 12. The other edge is ypreferably' out away on an arc to permit the sharp- 70 ening roller 13`to be moved `into engagement with the razor blade 14 for the purpose of. honing-of stropping the lower face of the adjacent edge of the razor blade. The roller 13 is mounted on a shaft 15 suitably journaled in arms 16 of a yoke-like member, the cross member of which is indicated at 17. Y The yoke member is pivotally supported by means 'of studs 18 in ears 19 formed or secured tothe guard member `11, as is clearly shown in these figures. The center of the studs 18 lies inthe yplane of the razor blade 14 so that Y the roller, when in eitherl of Y the positions l Shownin Figs. 1 and 3, will bear the proper relation tothe adjacent face of the edge of the razor blade. During shaving operations the roller will preferably be in the position shown in Fig. 1, in which position also it may be employed to hone or strop the lower vface of the idle edge of the razor blade. The roller may be moved out of engagement with either face and into engagement withl the other face of the edge of the'blader by manipulating the cross member 17. In Fig..3 the roller is shown in position to hone or strop the upper face of the edgeV of the razor blade.

The razor blade may be provided with three apertures, the loutside pair of'apertures receiving alining studs 20 on the clamp- 100 enlarged internally threaded head 24A of a plunger 25 movablegwithin the hollow handle l0, said plunger 25v being normally pressed downwardly, as shown in Fig. -l,b-y.means.

of the spring 26 Which bears against a "shoulder in the handle 10 and against a shoulder on afinger piece 27 which may be rigidly secured to the plunger 25-by a rivetor screw, as indicated.' When pressure is applied on the linger piece 27 th'e-spring 26 yields and the` razor blade and. cap may be moved upwardly, as indicated in Fig. 2, after Which'the 'capr'and razorfblade may be rotated so as to reverse the edges of the blade With respect Ato-the Vguardfandsharpening roller 13. i, .Asshovvn in Figs. 1, 2 and 3, the movement of the plunger 25 With respect tothecap 2l is preferably limited by a shouldered engagement betweenthe' stud V22 and: the enlarged headon the stem 25, the relation of the same to theiclamping cap 21 being suchy that the blade Will bestraight and in an unflexed condition when held against the guard member 11. fTo 'remove the blade it is merely necessary to unscreW the studf22 from Athe piece 24 by turning the finger piece 27, whereupon -the cap piece 21 Will drop 0H together with the blade.- Then any slight jarring of the cap will release the blade therefrom.

Inl-the modification shownv inFig.v 5, 'the guard member V30 is curved and' the shoulders on the stud`31- and the Vhead 32 vof the plunger 33 are so located and arranged With respect tothe clamping cap 36, that by turning the p'lunger'33by means of the vfinger piece 34 the blade 35 may be flexed as the blade is forced into the` arcuate Clamping cap 36. The sharpening roller 37 is supported on a-shaft l38 Whoseends'are rounded, as indicated at '39, exteriorly of. the arms 40 supporting the rroller. The arms 40 yare pivotally supported by means` of studs 41 in ears 42- which are formed on the guard member 30 in suchfa manner' as to `support the studs 41 in the plane of the exposed edge ofthe razor blade. When the roller is swung into the position shownin Figs. 5 and 6, the ends`39 of the shaft 38 engage in recesses 43 in the ears V42 toi-retainthe roller in the approximate position shown in Fig. 5. As shown in Fig. 7, the recesses'43 arepreferably made on a longer arc than the rounded ends 39 of the shaft 38 in' order that the movement ofthe sharpening roller toward the razor blade may not be limited.

razor blade 47 bears a proper angular shaving relation to the handle 46. In vother respects this construction is the same as that shown in Figs. 1, 2, 3 and 4 except that the sharpeningv roller 48 is preferably 4mounted on arms49 similar to the arms 40 shown in Figs. 5 and 6, and that the sharpening roller is held in each of its moved positions by a different means. The means comprises a projection 50 on each of the arms 49 adapted to engage the proper recess 51 ina supporting ear 52 when the rollerkis in the position shown in Fig. 8 or in a position corresponding to thaty shovvninl Fig. 3. v f v While the invention `has been described in particularity Withreference to the several embodiments shown, it is to be understood that other vforms or embodiments may jbe apparent to those-skilled in the art after understanding the embodiments hereindisclosed, andthatit is Ythe'intention toincludeall such embodiments`- Within theterms of the appended claims. i
