Fig. 3 is a side elevation with the handle and guard removed. Fig. t .is a detached side elevationof the guard and its clamp or holder,- the guard slipped endwise partly out of place in order to better show a portion of one side ofthe guard. Fig.

The blade.7 is made of a separate piece ofsheet metal from the back 8 and tang 9, and detachably secured within the back ashereinafter described. The. back and main portion of the tan are formed from one piece of sheet metal oubled u on itselfalo the middle of its length wit a rounded end. In the rtion the two sidemembers of the bent or olded metal are left'with a s ace. between that is. thick 1 enough for the 'ng iece 10 that is set in swaged into the formof a hollow. rod or tube .s o iamio oruumrama' mamas 1M August 1. 1m. molasses.

separated in order to leave sufficient space between them to insert theu per 'on of the blade 7. The outer on of roll or. hollow rod which formsthe back is closed by so a short cylindrical plug 15, the inner and of which plug is beveled off as shown inFig. 2. This pug may besecured in any manner as for example, bysoldering.

. The piece 10 of the tang is cut awe u at its inner end and for part of its le from the said end atthe top, in ordo'r'to leave space for the introduction of the ing latchj16 and its spring 17. .The In 16 is pivoted on the pm 18 at the "unctiou 10 of the back. and tang and is provi ed with a holding face or shoulder 19 for engaging a shoulder 20 on the confronting endofthe detachable blade .7. The spring 17 issecured in anypro r manner as for example, 15 by a: pin 21,-an he metal of the tang, so that it may bear with some tension on the I tail 22 .of the latch with a constant tendency to force the latch into the position shown in Fig-l 2. The latch may befomod against the spring to disen age the latch from the shoulder 20 of the lflade by pressing back on the projection or handle 23. The upper outer'corner of the blade is recessed or cut away so as to leavean upwardl and u outwardly inclined locking shoulder 54 for engaging with the beveled inner end of the plug 15 asshown in Fig.1. Thou r tion of the blade is made of a this pe 50 1 fill the slot or space between the fl es 1a of the back 8, while the upper or bac of theblade 7 is designed to rest ainst upper wall of the hollow back. eramr may be rovided with any desired-number of these etachable blades so that when one blade is dull, it may be removed and a sharp blade substituted therefor.

In order to changeblades, the handle 23 of the latch may be forced away from the end of the blade to disengage the shoulders 19 and 20' of the latch and blade. 'Ihen pulling on the heel of the blade will with draw that end while, the other end on the plug 15. When the heel 'end of the blade is out far enough to clear. the latch, 10. the blade may be moved endwise a little I) as to disengage the loc shoulder 24 from the plug 15 for removing t 0 blade. To

in a new blade, it is inserted in the tween the flangeswith the notchzg upper 1D of the way and against its spring and as soon.

as the blade reaches the position shown in Fig. 2 the latch will, by the spring, be forced into engagement with a snap and stopped in the position shown in Fig 2.

a flat sheet metal plate with the usual comb form at the lower edge. of this guard is designed to rest squarely against one of the broad sides of the blade and the other broad side of the guard is provided with a series of longitudinal grooves for adjustably'fixing the'guard in posi- I 'form the guard 29 for my razor of tion on the blade in connection with the resilient guard holder-26. This guard holder isformed of apiece of sheet metal that is A thickened back, and may be so appliedwithseparate from the guard and is doubled upon itself along the middle of its length and shaped at the bent ortion to fit and embrace the back 8 w e thelower art of the member'27 is fitted to one of the road sides of the blade for hearing thereon, while theopposite member of the guard holder has an inwardly projecting rib 28 formed 'at its lower edge for engaging'the desired one of the longitudinal grooves 25, as best shown Fig. 6. The guard holder is so formed that its two

clamping members

27 and 28 have to be forced. apart slightly in order to slip'the guard in between the razor blade and the member 28, whereby the guard holder is put under tension when the'parts are in the position shown in Figs. v 1 and 6.

T e guard and its holder may be both slipped uglon the razor together, or the guard may be st placed thereon and the guard holder afterwards slipped thereon. Both ends of the guard and its holder are alike so that they may be put on either end first, and thereby lace the guard on either broad side of the bl de as may be desired. By changing the guard sothat the ribbed member 28 is seated in a higher orlower groove in the series of grooves 25, the toothed edge of the guard may be made to roject more or less from the edge of the b ade. This'is especially useful when the edgeof" the blade is worn away so to make a narrower blade.

,While I have shown my guard and its holder in connection with a blade or back of a s ecific construction, the are equally app 'cable to an ordinary b ade made in one piece with the back, or to any blade with a out any substantial change in construction.

By my improvement I construct the blade, back and tang from sheet metal, whereby the construction is simpleand inexpensive. The

and is firmly and efficiently held in place.

One of the broad sides blade er is readily and 'convenientlyj dero tachalile or sharpening, or for substitution,'.

is substantiall a fiat sided blade, that is to say, it is free om ribs or.project1ons of any kind on its sides. It is inserted in the slot of the back by moving the blade edgewisein the slot towards the back, instead 0 slipfping the blade longitudinall into the end 0 the back towards the hand e, as in other detachable blades.

The com lete razor, without the guard, is substantia y'in the form of the made of sheet metal. a

The guard and itsholder are conveniently applied to either side of the blade for right or left handed use and the the guard teeth can be different widths.

I claim as my invention:

sided blade having at its upper outer corner a recess with an inwardly and downwardly slanting shoulder and at about the middle of its width on its opposite end, an outwardly facing shoulder 20, and an upwardly inclined end ace above the said s slotted back having near its upper outer end an u wardly and; inwardly extended holdin shou der fixed therein, and a spring actuated latch pivoted by its upper end within the oulder, with a old fashioned forged razor, although it is ro er ro'ectlon of Y lad wi th' lades of I Y 1. In a razor, the combination of a flat upper part of the said slotted back, and having an upwardly facing holding shoulder 19 near the lower outer end of the .said latch and belowits pivot, the said-shoulders at the upper outer-corner of the said blade and backbemg fitted toengage each other, andthe said latch being fitted to engage the holding shoulder 20.- and u Wardly inclined end face I at the opposite en of the said blade.

2. In a razor, the combination of a backandtang, with the back in the form of a slotted tube, a plug havin I fixed within the outer end 0 the said tube, a latch pivoted within the tang near its junction with the back, the'said latch having a a beveled end holding shoulder, and a projecting handle, a--

spring fixed within the tang and press1ng upon the said latch for holding it in engage ment, and a blade fitted to the said slotted tube and having at its outer end a holding shoulder for engaging the beveled end of the said In and having at its heel end a holding s ou der for being engaged by the holding shoulder of the sald latc 3. In a razor, the combination of the blade and back with a guard having on one broad side a. flat face for resting upon one broad side of the blade, and on its opposite broad side a series of longitudinal grooves, and a guard holder in theform of a spring clamp one of aving a longitudinal rib engagin m or a 1usta' y the grooves in the said series, holding the guard on the blade.

4'. In a razor, the combination of the blade to rest upon one-of the broad sides of the and a ribbed back with a flat guard adagpted blade, a resilient guard holder havin a tubuto rest upon one of the broad sides 0 the blade, and a separately formed guard holder lar back for fitting snuglg' the ribbe back of ha a tubular back for fittin snugly the the razor, the said guar holder having'two rib b d fback of the blade and de 'tely locatclamping members one of which presses upon 20 ing the ard holder relatively to the width one broad side of the blade and the other of of the b ade and two clamping members exwhich presses u on the guard and in turn tendin from the tubular back of the said presses the guar upon the, other broad side guard fielder, one of which members presses of the blade, and means for holding the said 10 upon one broad side of the blade and the guard at varying positions relatively to the 25 other of which presses upon the guard and in said two clampin members. turn presses the guard upon the other broad iLONZO A.
