To all whom, 'it may Concern.' v

Be it known tliet l, MORGAN FARKER, a citizen of 'ire United States7 'residing et Newport, charity ot Newport, mid Sttte of Rhode island. invented certain new and useful npr-otemente iii. Safety-Razors; and l do lioreliy. declare the following lobe e full, oezir, :md emot description of the in- Veiitioiij suoli. will eiieble .others skilled in the art to which .it eppertn-ins to malte md use the' Semo.

The .numeral l indicates the handle. and. the numeral 2 tlie elizuiir of the razor. The lilededioldingr end of the Slieiilc bladereteining means and. gimrretei ieg' means independent of one another. The Siecle-re ai ingmenus on the Simtel; comprise e pair of oppositelydireeted tongues 'l 4 which, in

liieet of invention to poride e;

shank and that, the etfect ol' the narrower portion .5 may. be produced by machining the metal of the shank to form longitudinal shoulders thereon. Either of these expediente imiy be adopted as may happen to be 'the` most adi/'eutageous under any particular manufaeturiiig circumstances. The blade has e. longitudinally extendiu)` slot in its Central portion as shown 1n t e drawings ity-guard 1s in place the po ioniiient oi the illude is further asured by tire upstzuiding Luoulders 6 on the tif-guard From e, consideration of Figs. fi, nud. Cf, it will appear that the shoulders 6 and. the tongue l eoperate t0 prevent the accidentel .rlisplenient of the blade sol whe-ri in use. by reason of the feet that.

'the blade cannot lie passed out from under the tongue 4t until it lies been longitudinally flexed and lifted und i "led over the slioulders fi. lu other wirds, tire 'tongue l and the sllorlders 6 effect a tlemre of tlie blade durin `positioiimeilt mid until the blade lies been slipped under tiie tongue to :i position such that its end will tell behind tile shoulders whereupon' lexure oitlie blade is relief'ed and it falls the position shown iii. l? l and To remove the blade it mi. t be llexed gain iu order to @leer tlie siioulders 6, i

The ssrfety-guerd 7 lies the ordiuer f double :serrated edges, aud it is adapt-ed to oe et taelied to and removed from thesliaulr without disturbing; the blade, in the following meneer. 'lllie 't-.Wo serrated end portions of tlie guard are simeeclmart and united to one another by arcuate straps 8 of a shape to elosel embrace the Slizizik 2 as shown in Fig. G, mid tliel'disteiice between the inner opposed edges of these guard. portions is slightly greater time the Width of the plate 5 aud lese than the width ofthe shank body 2me indicated in the drawings, so that the guard may be secured to the shank by slipping it on to the end of the shank with the straps 8 embracing the body of the shank '2 and the inner opposed edges of the guard ortions overlapping the edge shoulders ormed on the shank by reason of the fact that the platev 5 is narrower than the body vof the shank. For the purpose oil definitely positioning the guard longitudinally on the shank, the shank and the guard are provided with a coperating recess 9 and projection 10. The recess 9 is formed in the strap which is intended to lie nearest to the handie, the other end ot' the guard'being cut awayl to afford a finger-grip recess permitting the easy gripping and removal ot the vblade without removing the guard. This lend of the guard also has the shoulders 6 above referred to.

y Although I prefer to incorporate the several features of improvement hereinbefore described in a single safety razor, yet itvwill be understood that these features are to a large extent individually -useful in such razors, and all or only a part of them may be employed, as may seem desirable in any particular case. v

What I claim is:

l. In a razor, a shank composed of two permanently united lat members of different widths forming guard retaining'shoulders valong the longitudinal edges of the shank, and a guard composed of two parallel flat members lying in the same plane and adapted at their inner edges to rest upon the fiat shoulders formed by the wider member of the shank, said members being maintained in sp ced relation by transverse strap portions bent out of the plane of the flat members and adapted to embrace the wider member of the shank to hold the guard in place thereon.

2. In a razor, a blade, a shank, a pair of blade-holding means on the shank adapted to overlie the blade to hold it upon the shank while permitting its lengthwise movement thereon, a guard detachably mounted upon the shank, and means on the guard to cause longitudinal flexure lof the `clade as it is moved longitudinally of the shank and then to relieve the flexure of the blade and act in conjunction with one of the bladeholding means to prevent longitudinal displacement of the blade on the shank.

3. In a razor, a slotted blade, a shank proi vided with a pairof oppositely directed tongues abovethe plane of the shank adapted to extend through the slot in the blade and overlie the blade to hold it uponthe shank while permitting longitudinal movement thereon, a guard detachably mounted while permitting vits lengthwise movement thereon, and means on the guard to cause longitudinal flexure of the blade as `it is so moved and then to relieve the iexure of the blade and act as positioning means, requiring that the blade be flexedto effect its disengagement from the shank.

5. A safety razor havin a shank, a removable-guard and a bla e, blade-holding means on the shank adapted to overlie a portion of the blade to hold it to the shank while permitting its lengthwise movement thereon, and means on the guard to'cause longitudinal flexure of the blade as it is so. i

moved and then to relieve the fiexure oit the blade and act as positioning means, requiring that the blade be Hexed to eeet its disengagement from the shank, the said bladeholding-means having sufficient grip to hold the blade on the shank for stropping when.

the guard is removed.

6. A safety razor havin a shank, a detachable-guard and a bla e, blade-holding' means on the shank adapted to overlie a portion of the blade to hold it to the shank while permitting its lengthwise movement thereon, and means on the guard to cause longitudinal flexure of the blade as it is so moved and then to relievethe lexure of the blade and actas positioning means requiring that the blade be flexed to effect its disenn gagement from the shank, the guard having a finger-grip recess to permit the easy removal of the blade.

In testimony whereof I affix -my signature.
