S'PECIFIUATION formingpart of Letters Patent No. 798,?923, dated. July 1-, 1905.

Application lileil fl li l 26, 190%. Elerial l lo. 23 L419.

To It (oh/mt H; nt/ty eon/cent.-

lle it known that l, tl'r'ro Kain IFE, a citizen l. the llnited tit/ates, residing in the borough olilh-ooklyn, county ol Kings, city and tltate o'l blew llierk, have invented new and uscl'ul .l inrnovcments in blaliety tlhaving Devices, 01' which the following a specilic: tion.

ltly invention relates to improven'ieuts in, sal'ety shaving devices, by which l mean devices whose operation is essentially that ol shaving as opposed to cutting such, for example, as incisive cutting----an.d. which l'urther are n'ovided with a guard whose purpose it is to prevent any incision and also to limit the depth or extent el. shaving actkai thereol.

in my application Serial i-l .1207,$)8l7, liled ll lay 14-, Itldll, l. have illustrated and described a number of Forms ol sa'lety shaving appliances embodying the generic inventionol' which. the constructions set lorth. in this applic: tion constitute one or more species. lhe improvements set liorth in this application may no used either in. conjunction with or independently of various forms set l'orth in the said earlier application.

in the cmistruction shown and described in. this applicatiol1v the abeve-statml purpose oi the guard. is aceonrplished by its project- .ijng beyond the cutting edge of the blade, which projection not only manifestly prevents the possibility of any incisive cutting, but also compels the operator to keep the blade almost parallel withv the surlacc upon which the blade rests during a giv m -(.iperation.

The specilic devices in which. I. believe my invention will be most useful. are what are popularly known. as ctni'i-knivesz but the the same may be a iplied to any blade where it is desired to secure the results above stated and which. is used. as a shaving device as opposed to a cutting device.

lily invention will be l'ound cl exceptiomifl value wherever it is desirable to make it possible tor the user to vary the depth or extent or thickness of the shavings or slices which he is removing without any adjustment'ot the gmtrd.

lie the constructiens illustrated in th 2 acctnnpanying drawings this result is accomdished by leaving a space between the upper surlace ol' the blade, and more particularly the upper surl'acc conti;.3;uous to its cutting edge, and the lower surl'ace ot the guard and having a variation in the extent of this space at a plurality of points along said cutting edge. This result may be heightenedv er in.- creased by also varying the extent of the prejection of the outer edge of the guard beyond the cutting edge of the blade. .lt may l'urther be increased by leaving a space intermediate the inner edge of the guard and the Ulll. ting edge ol the blad and varying the extent o'l this space at a plur: .lity ol points along the cutting edge ol the blade.

hi the acconrpanying drawings l have shown a number ol modifications illustrating a variety of means for securing the guard in o ierative position with regard to the blade and also l'er allowing it to be moved a ay from and entirely clear o'l' both the cutting cdg and the upperand lower surlaees thereol.

in the drawings similar letters o'l' relierence rel'er to (an'respoiuling parts.

Figure l is a side elevation showing the guard behind the blade. Fig. 2 is a front view looking toward. the cutting edge of the blade. Fig. 3 is a side elevation oi a modilication. F 41s a rear view ol the same partially broken away. .l igs. 5 and 6 are re speetively a side elevz'ttion. and a rear view of another nnnlillcation with the casii'ig re.- moved. .liigs. 7 and t l represent still another modification each. in side elevation, showing the guard in two dill'erent positions. l ig. E] represents a slight variation. from liorms shown in Figs. 5 and (3, again with. the casing removed.

Oi course i. have merely shown in these drziwings the prel'erred l'orm ol' my invention, and it will be raidily umlerslood that substantially the same results may be accomplished in a variety ol' ways without departing I'rom my invention.

ltel'erring new to these drawings and more particulmly to liigs l and .2, A represents a handle which may be ol' any suitable shape, size, and nmterial; ll, a blade; agu'ard pivot-- ally mounted at a point designated Y toswing away from the blade. .lhe position and n'iovement ol. this guard may be controlled in any suitable :ma.une|.'----such, Llor example, as

byasprin (Indicated by dotted lines in Fig. 1.) As shown, Fig. 2, the guard and blade are so arranged. relative to each other as to leave a slight space between the upper sur face of the blade and the lower surlace of the guard. This space intermediate blade 13 and. guard C is designated by the letter E and, as will be seen, varies in extent at a plurality of p aints along the cutting edge of the blade. As shown, this is a eeomplished by bowing the guard intermediate its pivot and the outer end of the blade, which. results in the guard from the point at which it is bowed extending outwardly at an incline to the blade and to the outer end thereol. This result maybe accomplished in a variety of ways, all that is essential being to produce a variation in the extent of the space in question at a plurality of points intermediate the cutting edgeol the blade and the guard. .Evid en tly this variation. in space in question will allow the user without any adjustment of the guard to vary the thickness ol shavings or slices which he is removing. This ell'eet may be heightened. by also varying the extent of the proj ection of the guard 0 beyond the cutting edge of the blade B or, in other words, by shaping either the blade or the guard, or both, so as to vary the distance between the cutting edge of the blade and the outer edge ol" the guard at a plurality ol. points intern'iediatc the ends of the blade. The same result may still turther be increased byalso leaving a space F intermediate the cutting edge of the blade B and the inner edge of the guard C and by varying the extent ol" this space at a plurality 01 points intermediate the ends ol the blade. Of course the shape of the blade and guard may be varied to an almost unlimited. extent. It is preferable to have the guard arranged. with regard to the blade in such a way that it can. be moved when. desired. to an extent sullicient to leave the cutting edge and the various surtaces ot the blade tree and. clear. This has two ad vantages lirst, to admit. ol cleansing and wiping, and, second, to allow the use o'l the blade without interference from the guard. l have alreadydescribed the method ol accomplishing this, (shownin Fig. 1,) where the guard emitrolled by the spring, (shown in dotted lines.) swings upward and rearward away lrom the blade, so as to leave the ei'itire blade tree and clear. I have also shown a number ol methods oi accomplishing a similar result in. my alorementioncd application. ol May let, 1904:, each o'l. which. would. be applicable to the present invention.

Figs. 3 and. l illustrate an arrangement by which the guard C is swung on. the pivot Y in a lateral. direction to the position indicated by the dotted lines, which again entirely ire-- moves it from the blade. It is controlled by a spring M, which. is arranged. opposite the guard to engage with. the continuatimi oi. the

shank thereof extending beyond the pivot I In the construction shown in Figs. and (3 the guard C is capable either ol being entirely removed from the blade and handle or merely being swung back and clear from the blade, substantially as shown in form. Fig. 4. In this construction the guard C in its inner end is providez'l with a slot 0, having at its inner end a circular opening adapted to lit the shank of the pivot Y and at its outer end a Vshaped. opening adapted to lit and be engaged by the inner end of. a locking device or a slide G. This locking device may be ol any suitable cons ruction,provided it willengage with the inner end ol the guard C, so as to lock or hold the same in operative position with regard to the blade. It is shown as (mm'u irising a strip of metal or other suitable material guided by a couple of studs {j g, shown as being small screws .litted in slots g g. At its outer end it is shown. as bent out substantially at right angles, so as to p roject through an aperture or slot (1/ through the casing or handle A to 'l orm a projectimi or lingerpiece f tor convonitmce in inaniyuilation. \lhenever the locking device G drawn backward or upward, the guard (.l is unlocked and may be swung upward and rearward or entirel removed by merely pulling the slot 0 over the shank ol the pivot Y. it it is not desired entirely to remove the guard. C, substantially the same construction maybe used as shown in Fig. 0, excepting that the slot c is done away with. .lin this emistruction the guard C is pivoted at the point Y and will. swing upward. and rearward substantially .in. the manner shown in Fig. l, but instead ol. being controlled by a spring will be locked and held in operative position with regard to the blade by the loeking device G in the same manner as in. the construction shown in Figs. 5 and 6.

In Figs. '7 and 8 the guard O is shown hinged to the upper part or back oi. the blade 13 by two hinges or loops c c, engaging with apertures if 7r, arranged in the upper part oi the back ol" the blade. ()l." course the guard may be hinged in any other suitable manner to allow it to swing entirely clear l'rom the cutting edge and sides o'l' the blade .5. it will be noticed that in all the nuulilieations shown herein a guard which is bowed at a point intermmliate the ends ol the blade proper can. be used and can readily be either entirely re moved or swung clear of the cutting edge and side surlaces of the blade to have the same il ree l or cleaning, wiping, or any surgical operation. Any other relative arrange ment oi," the guard and blade which will pro duce the same result with a bowed guard may be employed.
