This invention relates tosafety razors.

" and has for} its principal object the provision of a relatively permanent blade" of high grade steel in a framefad'a'pted to as a handle during the shaving operation and a guide durlngthe op'eratlonsof str'opping and hon ng. v

It has long'beeni-cu'sto'mary to consider safety razor bladesjas small, thin strips of 1 medium grade steel intended for'juse only a comparatively few times after which they a're-j'discarded. Itis an object ofjthis invention to replace the usual. fl msy tempoj rary blades witha relatively heavyjbla'de of high grade razor steel which will lastprac j tically as long as the-frame and other parts of the device. Such blade is pivotally mounted within a frame and means-are provided to position it at any desiredangle relatively to the frame.

Another object of the invention is the provision of a holder adapted to-det'achably engage both the blade a1id'frame,and which can be adjustably securedto the frame in several positions;

A further ob'ect' of arrangement of means for bending the pen.

tion of the holder member adjacent the edge of the blade tob'ring such portionto-any desired positionrelatively to'the' edge of the blade. A further objector the invention is the arrangement of means for holding the blade during the stropping and honingoperations j and hones. v i I v Other ob ects and advantageswill be apparent from the 'iiolloiving -10 wherein reference is made to the accompanymg drawings illustrating a 'preferredem-j bodiment of my invention and wherein similar reference numerals designate similar parts t'hroughout the several views: 3

' Referring now to the drawings, the nu meral '5 designates al handleand 6 a holder frame detaehably securedthereto, as by a threaded'stem 7. The holder framefi issubstantially' U-shaped and provided with Fig. 10- is a detail section aka ubstan threaded apertures inits extremities for the reception of'the fulcrum screws 8, which are preferably formed substantially as shown in Fig. 10 with round tenons 8 adapted tovfit within'the apertures 95in the bladei9 to peri initread-yrotation of thexblade to position it at any desiredanglerelatively to the holder frame 6. The blade ;9 is preferably an'i'n tegral 'pi'ece of high grade steel having I relatively thick rear portion in which are located t'he apertures 9. and'a body portion tapering I gradually to the edge portion which is preferably beveledsubstantially as shown.' If desired the body portion of the" razor 9 may be hollow groundbetween the beveled ed e'portion'andthe'thickened rear portion, 'wl iereby only the beveled edge portion and the sides of the thickened'rear portioncontact a strop 10'during the'st'ropping' operation or a hone'during a honing opera- .tion (note F1g.'2)'.' Tlieblade canrbe honed and stroppedwithout being removed from the razor frame, and onthef usual bones and strops nowin'general use; The blade has a large wearing surface againstthehone'or stropand can always'beykept to a super= "keen 'e dge, after the manner of the o'ld-i'aslb ioned razors rather than the modern safety razor bladesofribbon steel. The honingor stropping "operation "with my improved;

safety razor is performed exactlylikethe hO-ningOr stropping of an oldfashioned razor except that the blade itself is grasped by the operator through the medium of an auxiliary holder 11 note Fig. and then sli d along thesurface ofthelstrop or hone as long i as desired. "The" auxiliary holder "11 1s formedwith a pairj of clamping tines 12 adapted to engage the body portion of' the i eralslipping of the blade during the honing.

razor intermediate the beveled edge portion and the thickened rear portion of the blade. In the illustrated embodiment I have provided a pair of notches 13 in the'body portion of the razor blade adjacent one side thereof for the reception of the tines '12 of This insures the the auxiliary holder.

grasping of the blade by the auxiliary hold? er at the right location. The notches 13 are preferably of suchdepth that the outer surfaces of the tines 12 will notextendbeyond the opposite faces of the razor blade and contactthe strop or hone instead of permitting the desired contactsonly between the bevelededge portion ofthe bladeand its thickened rear portion. During the hon-- ing or stropping operation the razor frame 6 depends from the thickened rear portion, of the blade 9 and acts as a-pendulum to maintain the blade in contact with the strop or hone. 'Moreover, the arms of'therazor frame 6 act as guides for preventing the lator stropping operations. Preferably the strop or hone used is of slightly less width than the distance between the arms of the U- shaped frame 6 tov permit a slight turning of i the frame so that theblade will set with its edge at an angle to the sides of the strop other than a right angle. This permits the usual positioning of the blade relatively to ,thesurface of the strop or,.hone,,and the arms of the frame then engage the sides of the strop to prevent deviation from the .desired angle while the blade is being slid alongthe surface of the strop or hone.

The operation of honing or stropping would, accordingly, be carried out by merely inserting the strop or hone between the arms of the razor frame 6 and holding it in substantially horizontal position. The handle 5 and frame 6 then hang from the thickened surface of the blade 9 and the blade rests upon the upper surface of the strop .10 substantially as shown in Fig. 2. The aux .iliary holder 11 is then inserted into the notches 13 of the blade and the blade with its attached frame and handle alternately pushed and pulled over the surface of the strop or'hone by pressure on theholder 1.1.

At the end of each stroke the blade is turned by partially rotating the holder 11 so that inainder the beveled edge portion of the blade is pointed in the desired direction, and this position is then maintained during the reof the stroke. These alternate strokes over. the strop or hone may be continned as long as desired. v

The blade may now be used for shaving, without detaching it from the razor frame 6, but after the auxiliary holder 11 has been removed. A guard member 14, preferably.

formed substantially as shown in Fig. 9, is positioned upon the blade 9' and the inner face of the razor frame 6. The gnardme'mber 14 herein shown comprises aguard plate I having rounded and dow-nturned teeth 15 secured upon the razor blade, thesecuring member 16 being adapted to snap into position over the thickened portion of the. blade 9 and press against thev inner face of the holder frame 6. The guard member and securing member 16' are preferably welded'or otherwise suitably united sofas tof form a' substantially integral piece. ,The angle at frame (5, substantially as shown in Fig. 7.'

The endmost guard teeth 15 are preferably bent upwardly and over the sides of the adjacent one end and a securing member 16 I of resilient material secured upon its opposite extremity, whereby the guard plate is blade to serve in positioning the blade upon the guard member and prevent the accidental relative movement of the bladeand guard member during theshavlng operation.

The free extremity ofthe securing member 16 is preferably curved'to provide a finger" engaging-projection 16 to facilitate the, po-

sitioning of the guard memberwithin the razor frame and its removal therefrom.

If desired, provision may be made for slightly moving the central teeth 15 of the. guard plate'toward or away from the ,edge.

of the blade9. As herein shown the endmost guard teeth 15 are provided with downturned apertured ears 19 for the reception of the stub shafts 2O eccentrically mounted.

in the ends of the adjusting roller 21. This roller is substantially cylindrical, but with the stub shafts eccentrically mounted in its. ends and j ournaled in the ears 19 of, the end most guard teeth, the rotation of the roller will serve to. bend the central-teeth 15 of the guard plate toward theblade 9 as the thicker portion of the roller comes between the shafts 20 and the 'teeth' tionof the roller moves in the opposite direction the resiliency of the metal j of the plate 14 willser ve to move the central jteeth away from'the blade 19,'the under surface of the teeth remaining always in engagement Then as the widerporJ .lau

with the periphery of the roller 21. A

knurled handle 22 may be provided for ready rotation of the adjusting roller 21. It.

will be noted that the adjusting roller is carried by the guard member l4 and is re,.

moved with the-guard member when it is de- 0 sired to strop or hone the blade. 'After the desired adjustment of the blade relatively to,

the central guard teeth 15 is once secured, it may be held indefinitely, the central guard the frame and blade may be swished in water standing in a bowl or the like, the operator holding to the tip of the handle 5. Likewise the guard member 14 may be readily cleansed by immersion in a standing body of water or held in the stream from a faucet.

Moreover, it will be noted that my improved safety razor is particularly designed for speedy action. The guard member 14 can be snapped on the'blade, and instantly removed by graspingv the projection 16. The blade, is readily stropped with a few strokes over the surface of the strop, and the cleansing operation can be quickly completed. The

frame 6 can then be disassembled from the handle 5 and the entire mechanism housed in any desired container. The edge portion of the blade 9 is preferably folded into the U-shaped frame 6 when the device is housed in a container. 7 1
