SAFETY-RAZOR.

Specification of Letters Patent.

' A li ti fil d March 31,1906. Serial No. 309,102.

To all whom it may concern:

Be it known that I, CHARLES BALLREIoH,

to .t ese en s it consists in the various featuresof construction and arrangement of,

parts adapted to" co-operate in'the manner substantially as hereinafter pointed out.

Referring to the accompanying drawings, wherein I have illustrated the referred embodiment of my invention, igure .1 is a perspective view of the handle, showing the blade in dotted lines in position to be inserted therein; Fig. 2 is a lan view of 'thehandle showing more particularly the su porting and clamping plate portion thereo Fig. 3 is a vertical longitudinal section ;Fig. 4 is a perspective showing. a way of detaching the blade-from the handle.

One of the objects of my invention is to make a complete safety razor which shall comprise only two parts, that is a holder for the blade and a separable .razor blade, and these shall be adapted and co-related to'each other so that the blade may be easily laced and held in operative position on the older and be detached therefrom, and when assembled the parts will be in the best position for practical use. Furthermore, 1 provide novel and exceedingly simple means for retaining the two parts of the razor in operative position.

The holder A, which is preferably made of a single piece of materi may be said to comprise a handle'portion 1, which is shown as of a tubular form and having the lower portion roughened or milled for convenience of grasping, and a yoke or. plate portion'extending therefrom. This yoke and plate portion may, broadly speaking, be said to be 1n the form of a platehaving a central 0 ening and the plate bent or partially dou led nearits center, thereby forming what may betermed the yoke portion 2 and the plate portion 3. The plate portion preferably extends at an angle something less than ninety degrees with relation to the yoke portion, as best indicated in Fig. 3. The plate ortion, which may be conveniently defined as a-supportingand clamping plate for the blade, is formed with a concaved face ortion 4-, and its free edge is preferably ormed with a comb gu'ard' comprising a series of teeth 5, with intervening notches 6,

and these are (preferably curved or bent toward the ban le portion, as best indicated in Fig. 3. What may be properly termedthe ends of this plate portion 3, are provided with clamping lugs 7, 7, forming recesses between their faces and the face of the plateportion to receive the blade. These lugs are preferably arranged adjacent the front edge of the plate portion near the bases of the teeth 5. Also formed on the supporting and clamping plate are guide stops 8, 8, which project slightly beyond the front plane of the plate and serve to determine the relative position of the cutting edge of the. blade and comb teeth. Both the yoke and clamping plate portions are recessed or cut awaynear their centers, as indicated at 9 and 10.,'for a p ose hereinafter described. 3

The blade 11 is rectan ular in shape, of relatively thin material aving 'a cutting edge 12 on what may be termed its front side,

and it is more or less flexible so that when in position in the holder it will present a slightly curved cross section as shown in Fig. 3, and by the tension thus exerted holds itself in place.

Such being the preferred construction of I the two arts constituting my complete razor, it Wlll be seen that they are not only very simple and chea of construction, but that they can be readi y taken apart and assembled, and when assembled are main tained in proper relations to each other. Thus, when the parts are to be separated, all it is necessary to do is to grasp the handle in the hand and with the thumb extendin over. the rear edge of the blade, it can be orced.

forward as indicated in Fig[ 4, where it is readily grasped with the fingers of the other hand and the separation is complete. In this movement the blade may be said to be removed sidewise from the holder with its edge in front and by pressure upon its rear edge. When the parts are to be assembled, the blade 11 may be grasped between the thumb and finger of one hand and, its rear edge 13 is placed over the comb-guard and between the lugs 7 and plate 3 and pushed in position a'certain degree when the rear edge 13 can be grasped 'by the thumb and finger extending in the recesses 9, "10,. and the blade drawn into position un il its rear edge abuts against the guide stops 8. In doing this,

owing to the concaved face of the ri id plate, the blade, being thin and flexible, wil conform to the plate and also be concaved, as shown in Fig. 3. The two will be held together in position by the spring or tension exerted by the blade. As it is clamped between the lug 7 and plate 3, as above indicated, the stops 8 will insure the bladebeing maintained in the proper relation to the holder. In thus assembling the parts, .the'blade may be said to be movablesidewise with its cutting edge to the rear during such movement, and it will be seen that by the aid of thecut-away portions 9 .and 10 in the yoke and supporting and clamping plate, the blade cannot only be readily dlsplaced from its pro er osition in removing the blade but. can he rawn into its proper-position afterbeing once'started, or placed between the lugs 7 and plate 3. This can be done without cutting or injuring the hands of the operator.

It will thus be seen that my device comrise s a holder in one piece, embodying the handle and clamping plate with a concaved front adapted to receive a'thin, flexible blade and with clamping ln s and guide stops for insuring its retaining t e proper position; the blade being held in'position by the tension it exerts through the medium of the curved or concaved face of the clamping plate and the lugs.

What I claimis 1. In a safety razor, thecombination with a flexible blade, of a holder comprising a'handle portion and a su porting plate, said plate hav ng a concaved ace whereb two bearing surfaces are provided for the b ade in its unflexed state, and lugs on said plate between which and the face of the plate said blade is ada ted to be clamped, the bearing faces of sai lugs being arranged between the said two bearing surfaces of the plate and closer to the face of said plate than the outer surface of said blade in its unflexed state.

2. In a'safety razor, the combination with a flexible blade, of a holder comprising a handle portion and a su porting plate, said plate havmg a concaved ace whereby two bearing surfaces are rovided for the blade in its une flexed state, ugs on said plate between which and the face of the plate said blade is ada ted to be clamped, the bearing faces of said lugs being arranged between the said two bearing 1 the eari ng faces of said.

stops and said plate having a concaved face whereby two bearing surfaces are provided for the blade in its unfiexed state, and lugs on said plate between which and the face of the late said blade is adapted to be clamped,

ugs being arranged between the said two bearin surfaces of the plate and closer to'the face 0 said plate than the outer surface of said blade in its unflexed state I '4. In a safety razor, the combination with a flexible blade, of a supporting plate there- .blade whereby two bearing surfaces are provided for said blade in its unflexed state, and

, ing bearing surfaces, a flexible Mae, and lugs arranged at the ends of said plate portion between the bearing surfaces and clamping said blade against the concaved face.

6. A safety razor comprising a holder having a handle portion and a supporting and clamping plate concaved on its su orting face providing bearing surfaces and having clamping lugs at its ends between the bearing surfaces, and guide stops on its rear, and its rear portion being cut away between the guide stops, and a flexible blade, whereby the parts are arranged to flex and hold the blade 1n place on the, concaved face of the plate and to permit the blade being pushed from the,

.rear'and removed with its cutting edge to the 'for having a face concaved relative to said 1
