acter which may be readily and quickly ap-- plied to the blade of the ordinary form of razor to form a safety guard therefor. A further object of the invention resides in providing a guard bar the ends ofwhich' are formed with upwardly disposed projections which are adapted to interlock with the end edges of the razor blade and another object'of the invention-resides in providing a bar which is adapted to be sprung into position.

of means "for the dispositionof the guard bar to one side or the other of the blade so as to permit the device to be-readilyfdisposed in position'for use with either hand;.

sides in providing a device which is. cirtremely simple and durable in construction,

inexpensive to manufacture and one which construction, combination and arrangement throughout the of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims. I I 5 In the accompanying drawing forming a part of this application, Figure 1 is 'a side elevation of a razor showing my improved safety guard applied to use on the blade thereof. Fig. 2 is a horizontal section through the blade as seen on line 2-2, Fig.

1, showing the manner of. applying the guard thereto.

3 is a vertical transverse section through the guard. Fig. 4 is a perspective view of the guard bar removed. 4 In describing my invention, I shall refer to the drawing in which similar reference characters designate corresponding parts several views and in which 1 1 indicates a handle member of the type provided in the ordinary form of razor, to

tegral upstandingprojections 9 and 'l0,-- whic h-are adapted to respectively engage the front and rear end edges of said blade 11 'rear: end projectionor heel po'rtion'lO of I A further object resides in the provision intb engagement with the-rear end edge or the same in such 'posit-ion, said end isu'c'j duped in thickness for apportion-of its Still'anoth'er object 'of'the invention'r'e-' upwardly facing shoulder which is pivoted the shank 2 of the blade 3 This blade is of the ordinary form used in razors of this type and in order to provide for the guarding of the cutting edge there .of, the toe or outerlend edge of said blade is provided with a stud or the like 4 which 1 1. is disposedjmmediately adjacent the rear or i back edge of said blade, while the heel or 's inner end edge of said blade is cut away to 5 form an upwardly facing shoulder 5'.

The guard proper comprises a bar 6, the side faces of which are beveled as shown at 7 and provided with notches 8 arranged at regular intervals throughout the length thereof. The-front and rear ends. of this I bar are respectively-provided with the inand the upstanding projection 9 has an" .opening ll formed therein which is adapted to'receive' the stud 4 therethrough. The

the bar 6'isadapted, to be sprung or snapped heel'portion of the same and in order to lock length to provide adownwardly facing. shoulder 12 which'is 'adaptedto engage the t 5 onthe heel por tion of the blade, a

lVhen' the guard bar is locked into engagement with the blade '3, through'the medium of-the meansabovedescribed, the ;--:-2

extreme free end ofthe upwardly projecting portion 10 of said bar,- which is bifu'r catet ,as shown at 14, is straddled over theshank 2 a ulthe-guard'bar proper is dis posed below the cutting edge of the bladei I have provided, however, for the disposi-' tion of the guard bar to the one side or the other of the cutting edgeof the blade and to this end, the portion of the extension 10 between the shoulder 12 and the bifurcations 14 thereon, is provided with a pair of upwardly convergent channolsor grooves 15. v These channels are adapted to receive directly therein the inner end edge or what may be termed the heel of the blade 3, and as the one end of said guard baris pivoted to the blade, while the other end is sprung into position thereon, it willbe appreciated that said guard will be .securely' held to the blade ineither of its adjusted positions. Thus, should the guard be disposed on one side of the blade and'it is desired to use the same on the Opposite side thereof,

will only be necessary to press 'upon. the

. heel or end portion of the guard-in the 5 proper direction which-will move the guard so that the same will be locked to the blade in the opposite channel or groove thereguard, the extension 9 is provided on the side edges thereof-with the lugs 16 which extend on opposite, faces of the blade when .1 ,15 properly posltlonedh- The-channels 15 are.

.50 arranged that the up-p'er edge of one -.beveled face or the other of the bar 6, will register-with the cutting edge of the blade, on the disposition-of the guard to the one 20 side or the'other of said blade.

In practice, should it be desired to apply. the guard bar to the blade, the same is first positioned'so as to allow the stud 4; to be 7 l entered in the opening 11 of the extension 9, whereupon" the opposite extension 10 is sprung into engagement with the heel or inner end; edge of the blade so that the shoulders 45 and 12 interlock. Asstated abo e, this guard may be disposed to the one side or the other of the blade, as de-Y sired,- bymerely placing a pressure on the heel portion or the'extens1on 10 ofsaid i guard, which will cause the one or the other 1 ''of said pair of channels or grooves 15 to enga e the-end edge ofthe heel of the blade 3'an it will be appreciated that the spaced studs 16 on theopposite extension 9 will limit the movement of the guard with respect to the blade. Should it be found 40 necessary toremovethe guard, it will only be necessary toplace a pressure on the heel or'extension 10, which pressure will spring the shoulder 12 in saidextension out of engagement with the shoulder 50f the blade 'so that guard proper may be readily re- .moved from the stud 4. v

From .the foregoing it will be seen that I haveprovided a simple, inexpensive and efficient meansfor carrying out the objects,

of the invention and while I have particularly described the elements most well adapted-to perform the functions set forth,

it is obvious that various changes in form, proportion and" in the minor details. of construction may be resorted to without.de-,55 parting from the spirit or sacrificing any ofthe principles of the invention. Having ,thus described his invention, what I claim is:

the ends of which'are bent upwardly to" form projections thereon, the one of saidv projections having an opening adjacent its? .free end and also provided with spaced lugs 5 adjacent its lower end, the other of said projections having a shoulder formed-on the inner face'thereof adapted for engagement with the end of a blade, said projection being also provided with a pair ofup 'wardlyconvergent grooves leading from said shoulder and adapted to receive the endof said blade therein. p 2; In a razor guard, the combination with a bladehaving a stud formed on the one endedge thereof and, provided with an up- .75 wardly facing shoulderon theopposite end I edge thereof; of a guard bar, Qthe ends of which arebent upwardly to form" projecttions to embrace the end edges of sai the one projection being provided with an 89 opening to recc ive ,'sai stud. therein, the other projection ha 'vmg a downwardly 'fac-, ing shoulder thereoneadapted. to .besprung -in'to engagement withjheshoplderoh the projection: having its free end bifurcated to receive the shank of. the blade therein and also having a pair of upwardly con; j .vergent channels extending from the-shoulmentioned end edge of the blade therein,

and means to limit the swin ing movement of said guard bar on the blade. In testimony whereof I hereunto aflix my 7 ORIEL E. CRATER.
