andresident of Chieagoftook eounrv. llli- If nots, have invented a eertain new and ost-lu! i Im rovemeut in Safety-harnas. ot' wlneh the fol owing is a speeilieation.

i the floll't.

My Invention mntemplates eel-tain 'ine provements wlneh are lireeled more especiully to the idea of having the upper or top surfaee of a safety razor blade imeovered or left fullv exposed and thus adapted to b' held flat-wise upon the eheek of the uwr.

To the fon'going and other ns'l'ul ends m v iuveiitioneon-ists in matter.` hereinafter @t forth and claimed.

ln the aeeompzurviug drawings Figure l is a seetional \iew of :i razor embodying the riueiplesl of nl v invention: l"ig. :i plan oft le same: Fig. Il is a vlew similar to Fig. l. showing anotln-r form ot' in v invention: Fig. -t is a plan of the mme: Fig. .'i is n view Silnilul' to Fig. l. -l|o\\il:g another form of my invention: aml Fig. l is a plan of the same.

lu Figs'. l and the. plate. ha. teeth a and rear holding lugs u'. The clamping jaw ii has holding .lugs l and a stem i. lQuid jaw is adapted for morena-.ut iu the plane of the bhule ('A. ulul has' a bevel 1' in its stem. 'l'lze haudlel) is rigid with the plate and provided with a soeket for said stem. Spring l'i presses the stem outward aml tends to move the jaw li away from the blade. Said holding lugs eaeh engage and overhang a eorner of the. blade.

screw a2 acts on a stop to prevent the stem from falling out of ite soeket. 'lhe handle is hollow and provided w-ith an operating screw l". Said operating s( rew has nu upper end portion f adapted toengage the bevel b. A tlmmb piece f is secured to the screw for operating the same. When the screw F is rotated one way the end ores downward aml allows the jaw B to disengage its` lu from the blade. The blade can then be li ted from the plate A. Vhon the screw is rotated the other way the end f then moves up and causes tho blade.

lu l"igi. tl and `t the stem (l of the' movable Jaw is provided with a nut y. A spring g is interposed between this nut and the shoulder l 'f The screw II has its u )per ond adapted i engage the said stem With be removed guard the jaw to engage and hold lu Figs. I uml the rear edge of the bhnh.l l is not sharpened and is provided with a :lmvnwardly de|wnding lip or ridge .1'. The movable jaw .l is at the rear instead of at This jaw'is adapted to clamp the li i or rldge z' again.-'t the real' edge of the plate l( upon whieh the'lilade rests. Said 05 mw has a stem j provided with a bevel i'. Il will be umlerstmal of eouise that said bevel is formed at the elul of a slot in said stem. as shown in Fig. 'l`he upper end ot' the serew l. engages said bevel. spring .\l moves the jaw outwardly. 'ith this arrangement the entire upper surfaee of the blade is exposed. and there are up projections 1 rising above the same.

ln 'the forms shown in Fi 1 to -i the 15 lpper surface of the blade isiiill e.\|msed. andthe lugs do not rise but szlig tl v above such surface. In these forms. however, the blade is double edged.

In Fig. 5 the screw N )reveals the jaw .l l0' from being diseonneete from the blade holder or plate K.

ln eaeh form of nl v invention. the eavity for the-nl n'ino' is loeated midway between the ends of t le blinde. 'l'hus the stem and spring B5 are. in eaeh ease. loeated eentrally of thil holder. ln this way the ends of the holder are alike and the razor is balaneed.

'hat l claim as my invention inzy l. ln a safety razor. the combination of a blade. a plate provided with a guard, a clamping )aw movable. in the plane of said blade, means for supportin f said jaw for movement in the plane of t ie blade. and a handle. a screw operable at the lower end 5 of said handle. and means engaged by said screw for lcxflcing seid jaw.

2. lu a safety razor. the mnnbination of a double edged b ade. a guard. a movable jaw provided with a pair of lugs engaging and 10 overhimging the two forward eornerx, of said blade, a plate provided with two luga engaging and overhanging the two rear corners' of Raid blade, a stein ou said jaw extending toward the rear of aaid ilate, a spring holding the jaw in one direction, and a www extending upwardly und en ging said stein, 'said plate rovided with a mndle at. the lower end o which said serew is operable. o

3. In a safety razor, the combination of a double edged blade, l. holder provided with a stat for the blade and holdin lugs for-l said blade holdin device arranged lengththe corner portions thereof, eaci lag rei wise of the hand e, und means coperating cessed to receive and overhang a corner portion of the blade. the two front lags being connected to forni a pair, the two rear lugs being connected to forni another pair, means for supporting one pair ot' lags for niove ment toward and away from the. other pair, means including a sert-v extending.lenwtlil wise ot' thc handle l'oi- Rwlting the ngs against relative morena-ni when the blade is in placc.ii guard loi' tlic blade. :i liainllc rigid t willi one pair ol' lags. and a slidii'er conncc tion between the liaiidliand movable pair of lags. engaged by -aid screv.. said lags ireventing` edge isc displacement of the li :ide in all directions.

-l. ln a .sah-ty razor. ilie combination of a reversible doiible edged bladea holder pr0- vided with t'ront and rear holding lags, each lng holding the blade against endwise therewith whereby the normal action of the spring is opposed and overcome to etfect the insertion and removal of the blade.

t'. In a safety razor, the combination of I' tlat rectangular bladehavingr one or more cutting edges, a blade holding device therefoi' comprising a pair ot' clamping jaws, one tixed and one movable thereon, a spring normally actuating the lnovablc clamping jaw in the lane of the blade, a blade seat 0n Said 'tixed clamping jaw and .i guard for the cntting edge or edges. means on said jaws receiving and ovci'haiiging opposite edges of, the blade and holding it tiiitwlse oli the blade seat and tixed from displacement in any difi'ection. a centrally disposed handle on the ander side of the blade seat` means on Said blade holding device arranged lengthwise :ind `'idewise displacement. iiicanS integral:

with the .said lngs t'or engaging the top of the blade io hohl the saine Ilatwise in place on said holder. a guard for the eiitting edge of the blade. a handle for tlnl lioidci. and i means including zrsliding connection in the l holder engaged by the iipper end of a rotary sci ew evtending lengihr. ise ol' the handle for locking -onie oi' said lugs relatively to the iillicitsl lo gllp tlnI lilntlc.
