/NVENTOF -W/TNESSES ATTORNEYS 2oV and to permit described hereinafter and BENJAMN KIAM, OF NE w ORLEANS, lLOUISIANA.

- SAFETY-RAZOR.'

No, 914,957. l l Specification Application lfiled November Toall whom'it mayconcern:

Be itknown that I, BENJAMIN KIAM, a citizen of the United States, and aresident of New Orleans, inthe parishof Orleans and State of Louisiana, have invented a new and Improved Safety-Razor, of which the following'is a full, clear, and exact description.-

An object of the invention -is to provide a simple, inexpensive and efficient safety razor,

'employing a detachable, stiff or a flexible blade and provided with two cutting edges, and co-acting with a guard to preventv the user of the razor from cutting or otherwise injuring himself.

A-further object of the invention is to rovide a safety razor having a curved, flexible, detachable blade anda guard to co-act withA the .blade, and arranged to be clamped againstthe latter to straighten the same and thereby provide it with suiiicient rigidity, .its adjustment with respect to the guard. I

A still further object of the invention is to provide a ,safety razor having a'gcurved lade, 'and co-,acting therewith an oppositely curved guard, 'whereby agspaceis provided 'between' the blade and the guard to 'permit the escape of through. j

The invention consists in theconstruction and combination of parts to be more fully particularly set vlather and the like thereforth in the claims.

Referencev is tf0 be had to the accompanying drawings forming a part of this specification, in'which similar characters of reference indicate corresponding parts inall the views, andin whichm Figure 1 is an elevation showing the prevferred form -of-my safety razor; Fig. 2 isa longitudinal section of the device on the'line 2-2 of Fi 1; Fig. 3 is a plan view showing a part bro en away and a part in cross-sec,- tion; Fig. 4 is a perspective view showing a blade-of the type used in connection with my razor; Fig. 5 is an elevation showing a razor of modified form and having a part broken away; F ig. G is a longitudinal section on the line 6"-5 of Fig. 5; and Fig. 7 is a plan view of a modified forni showing a part broken away and a partv in cross-section.-

Before proceeding to a more detailed explanation of .my invention, it should be understood that I can use a stiff or a flexible blade in connection therewith. It has been found that the use of a thin, flexible blade,

preferably having two cutting edges, permits .great saving in time and expense over the ordinary form of safety razor blade, asy the 'flexible blade requires less steel or other material in its manufacture, and consequently can be made at a comparatively lowcost, thereby permitting it to be thrown away when dul Ilurthermore, the flexible blade when used in combination with a guard, can

more lor less closely with respect to the guard, and in consequence, it permits the regulation of the shaving operation in regard to the closeness ofthe removal of the beard. The

i blade which I preferto use in connection with my safetyv razor differs essentially from other flexible blades now in use, in that it is nor- Inallycurved and is straightened or b ent into a'form of flatter curvature by the engagement therewith of the guard.

Referring more particularly to the drawings, the preferred form of my invention vas shown in Figs'. 1 to 3 includes a handle 1 which may be of any suitable form', though preferably consisting of a hollow cylindrical shank which can be conveniently gras ed by the hand of the user. Atone end, the liandle correspondingly threaded end of the handle. rlhe headl 2 has an vopening therethrough for a purpose-which will appear hereinafter. The head 2 rigidly carries a cross-bar 3. The latter' has rigid side-bars 4, preferably formed integral therewith and constituting, withthe cross-bar, the. blade and guard holder. The side bars 4 at the upper ends have inwardly disposed fingers 5. Near the fingers 5 the side bars have inward projections 6 so .formed that the distance between the projections is less than the corresponding distance between the side bars near the cross-.bar 3. j

I refer to employe concave, transversely flexible, and detachable blade 7 fashioned from steel or other suitable material, and decreasing in thickness from the center toward the o posite longitudinal cutting edges S.v The blade, owing toits curvature, of course possesses greater ,flexibility longitudinally thereof, but bendseasily transversely of its length. [it the opposite end edges, the blade thickness of the blade at the middle, the flexibilityresides primarily in the cutting edge portions of thesame. n

1 has a head 2 mounted in position by meansof a threaded portion 15 secured within the 1s lprovided with recesses 9 preferably rectangular forni.` Owing to the greaten be bent by the latter so'that it adjusts itself The length of theblade 7 is such that it permits the insertion of theblade between the side bars 4 below the inward proj ectio'ns 6 of the latter. Thus the blade can be placed between theside bars and when itis moved upward alon the same the projections are received by t e recesses 9, which 'thus' serve to hold the blade in position between theside bars with the upper face resting against the under sides of the fingers 5. In the preferred form' of my invention I employ a uaid 10,

' having a curvature the converse oft e curvaforme ture of the blade, and provided with laterally7 extended seirations 11 at the opposite lon itudinal edges. The guard edges engage t e blade near the nuttin edges of the latter in the usual manner. and a uard of opposite curvature, a space is (I between the blade and the uaitd which permits the lather, moisture, an severed bristles to escape freely along the cut` tinged eof the blade, into the space between `t e blade and the guard. 'l'hi'sl construction prevents the collecting of. lather or other material at the cutting `edge ofthe blade, to impede the operation of the same.

A stem 12 is rigidly secured by means of a rivet 13, or in any other convenient manner,

near the middle of the guard 10, and has the lower portion 14 threaded. Thestem 12 extends throu h an opening of the cross-bar 3 jand the hea portion 15. A correspondingly f threaded, manuallyoperable burred nut' 16 entire length thereof at the middle.

this form of the/device I employ a guard 1()a 'ism arranged upon vthe stem I4. Within the 35 opening of the head 2and by means ofthe same thestem can be moved longitudinally of the handle. to adjust the guard with re spect to the blade.- By forcing the guard against the blade the latter is bent transversely, and is straightened to a degree corresponding tothe pressure of the guard -a ainst the blade. Thus, by bendingL the having a'curvature similar tothe curvature of the blade though of flatter-curvature than the normal form of the blade. The serrated' edges 18 of the guard 10i1 extend beyond the olpposite cutting edges of the Ablade as is s own-Inost-clearl in Fig. 6. By forcing the guard 10 against the blade, the latter is straightened and the distance between the cutting ed es and the edges of the guard is adjusted t ereby. I Theguard 10i hasQnear the center, a socket 19in which is movably y employing a blade y blade and said guard.

l arranged a ball or head 20 of a stein 2,1. The

handle '22 of -the modified form has alon itudinal bore or opening through which t e stem 21 extends. The iatter has a threaded portion 24, co-acting with a correspondingly threadedportion 23 of the handle, Ato permit the adjustment of thestemlongitudinally ofthe handle. At the lower end the stem has a laterally extended burred head 215, by means of which the stem can be manipulated. As the guard inthe modified form has a movable connection with the stem, the Auard adjusts itself closely and automaticaIly withl respect to ,the blade when it is forced Vthereagainst by means of thel stem. At the same time the guard is ievented from becoming detached when it is loosened to permit the insertion or removal of a blade.

As the flexible blades which I employ in connection with my safety razor are of greater' thickness near the center than at the cutting edges, they have sufficient rigidity and require little support. 5 of the preferred form will securely hold the blade againstpr'essu're of the guard. modified form the cross-piece however, provides a back or brace lfortlie vb'lade alongthe entire length thereof, and conseqluently, with v 95 this form'of the invention the b ades can be made thinner. It will be understoodthatfif so desired, I canA use stiff blades with my Thus, the finger In the razor, provided they are suitably formed for the urpose.'A
