SAFETYIRAZOR.

Specification of Letters Patent.

Application led October 2, 1906. Serial No.A 337,152.

vention is the production of a holder, for

such blades, of. pronounced simplicity and having only a few parts.

In the device o1c my invention, the thin removable blades are not sharpened on both or opposite edges, they .are n`ot perforated for any engaging devices and they are not bent transversely by the holder as has heretofore beenusual with safety razor blades of this class.

In carrying out my invention I provide a body member forn'iing a holding frame for receiving the thin removable 'and interchangeable blades one ata time auditor en'- gaging the same around three sides oredg'es (the fourtlredge or side being sharpened. for cutting);

In this frame iis pivotally mounted a swinging guard comb whose outer surface bears upon the razor blade to press the same against the holding edges or frame of the body member. The vfree ends ofthe comb teeth are slightly curvednind extend beyond the cutting edge of the blade. The body meniberis secured to a tubular handle, the `tree' end of which is formed with a screw thread, and a rod passes through the tubular handle which bears against the swinging guard comb to forceand hold the blade in position and said rod is secured to a manually actuated plug threaded to screw` in position, the same is bent longitudinally,

that is to say, the straight sharpened edge of the blade is slightly bowed, the curvature thereby imparted producing the same functional etfect in the use of the implement for shaving as does thc curved edge of the blade ot an ordinary razor.

In the drawing, Figure l is an elevation e at the cutting side of the implement with vthe handle broken oli), Fig. is a' plan of the parts shown in Fig. l, Fig. 3 is a vertical longitudinal section through the entire i1npleinentand Fig. l is a vertical section through the body member with the guard comb lowered for the introduction of acutting blade.

The body member a. as will be seen by reference to Figs. l, i). and 3 is ot elongated pro-A and reducedI materially in thickness so as not to present any blunt or oliposing metal to ,interfere with the act of shaving.

b represents a tubular handle to the upper end otwhich the head portion (il ot the body member is secured and formed to all intents e and purposes substantially intt-gral, the said head being centrally perforated and the lower or open end ot this tubular handle is orined Awith a screw thread 1, the sides -ot the body member being provided with support ledges 5.

'l provide a. swinging guard comb o adapti ed to tit. within lhevtranie of the body vmember and provided with lugs 6 formed as engaging hooks extending through openings in the hack portion ot the body member so as to maintain a pivotal relation of the "guard comb c with the body member'v to pre' vent accidental separation of the parts; said lugs providing 'for the swingingl of the guard comb between the over-turned edges 2 and 4lwhich torni stops in an upward direction and the support ledges 5 which form stops in downward direction; the said guard comb having teeth c1 lthe tree ends ot which are overturned and bent at a slight downward inclination. As will be seen from Fig. 3, this guard comb is in cross section flat and straight, While from l` to thel extent of this cient if quite slight although it may 1fv de- Fig. 1 it will be seen that the said guard comb longitudinally is slightly bent or of an arched configuration. Ido not limit myself curvature; it issuttisired, be made more pronounced.

d represents the razor blade as over-lying the guard comb'c with three edges of the blade extending under and held to the overturned edges 2 3 4 of .the body member by the upward pressure of the This pressure is produced by a rod e which passes through the frame of the body member and is formed with a threaded plug f which is adapted to turn into the lower pfen and threaded end ofthe tubular'handleQ plug being preferably provided with a knurled'head f1 for rotating the same. Itl

will therefore be apparent that as this knurled head and its plug and rod are turned in one direction the free end of the rod bears with force against the under surface of the 'guard comb raising the same and clamping K,

the razor blade in position, whereas in the reverse position. the loweringor removal of the rod e permits the guard comb c to drop by gravity' and to free the razor blade d from the grasp of the parts holding the same. The razor blade when freed assumes a flat and straight form. It is removable and the parts are adapted to receive a duplicate thereof that may be sharp and scrviceable for shaving, so that these razor blades are removable and interchangeable; Fig. 4f showing the position just described and adapted for the removal of one blade and the insertion of'another, and in this position tained without going it will be noticed that the guard comb c which has dropped by gravity when released now rests upon the support ledges 5, no razor blade being shown in this 'gure.

From the foregoing description andaccompanying illustration, it will be apparent that the razor blade of my inventionin use has a convert outer face and convex cutting edge; that this convex face is presented to a shaving'sur-face; that the path shaved is less than the whole length of the cutting edge and because of the curvature the shaving is cleaner than is produced with a straight edge which has a greater bearing surface, consequently a cleaner shave is ob g over'the face so many times. The shaving edge of the blade is sharpened when straight and is under tension when curved and it is 'believedvthat this tension prolonge the useful sharp life of the blade, making it unnecessary to sharpen fre quently. The razor blade is fiat in its initial condition. t is iliexible longitudinally of the said rectangular blade, that is to say, it is fiexible in the line of its sharpened or cutting edge so thatl said cutting edge is curved in use,

A shaving and that the manner guard comb c.'

l'said From the illustration and foregoing description it will be apparent that the device of my invention is composed of a very few parts, that these are accessible degree for cleaning and wiping dry after of removing one razor blade and introducing an interchangeable sharp blade is exceedingly simple.

lVhile I have hereinbefore described the thin flexible rectangularv razor blade of my cutting, curved form under pressure and tension, I wish it to be understood that yI do not limit my invention in this particular as said thin rectangular bladey may be made normally stantially it over and'upon the curved upper surface of the swinging guard comb without in any manner departing from the spirit of 4my invention; the `manner of sharpening a straight or curved blade being immaterial and forming no -part of my invention.
