"1 9 v T Generally,described, the Y invention p'rO- I vides, a large curvature'razor having a seat and 'g'uardjmeniber' to receive a doubl'e edged being removablyheld together by a conven- 'tional screw and handle construction. lo afford a large curvature, the-blade may-beelongated'between the cutting edges thereof in proportion to the angle of the curve.

Preferably this, angle is approximately 120 degrees, the blade being comparatively longv in consequence, so that the curve is sufficient to avoid undue strain on the blade andto' length of a cutting edge.

central part thereofmay be made narrow, with its lines diverging toward the cutting edges. Also the central part may have one or more openings or slots to reduce the cross section thereof. Since razor blades are made of a high grade steel, the desired fiexure thereof can be readily accomplished. lhe razor may be constructed to cause most of the flxure of the blade to occur in the central part thereof. The curve of the blade has a stiffening edect upon the edge portions thereof, which renders feasible a razor constructed according to the principles herein defined. Utilization of the resilience of the blade is effected with the cover bearing upon the razor at selected points adjacent to the cutting edges for stidening the latter and to cause it to follow predetermined lines and with the cutting edges adapted to lie substantially fiat against the surface being shaved. Thus a cleancutting action is obtained on the hair without a tearing or pulling thereon, producing a smooth shave. The cover member may be made of sheet metal with downwardly bent marginal flanges to engage around the side edges of the lower or guard member of the razor. To interlock the razor parts any suitable means may be provided, one possible form of which is illustrated herein.

Referring in detail to the drawings, 10 denotes a device embodying the invention. The same includes a razor for a novel double edged blade 11 more p rticulariy described hereinafter. The razor comprises a base member 12 having a seat 13 for the blade 11, a holding or cover member 14' for the blade above said seat, and handle 15. At the ends of the base member 1 are conventional guards 16. Any suitable means are provided to removably interconnect the

members

12 and 14, including a central screw 1'? on the cover member, adapted to pass through a hole 18 in the base member, to be threaded into an axial bore 19 in said handle.

The blade 11 is stamped or otherwise formed of plane sheet steel, and provided with opposite cutting edges 20. Intermediate of these edges 20, the blade is considerably elongated, so that its length may be equal to, or preferably greater than the This permits the blade to be flexed into any desired curve and with any required angularity. To facilitate the flexing of the razor blade, the same is narrowed intermediate its ends to form a neck portion 21 toward which the opposite cutting edge portions taper along the side edges ea ers To hold the blade in place in the razor, the cover member 14 has a short ridge 23 extending in opposite directions from the screw 17 lengthwise of the said member. T he blade 11 is provided with a correspondng hole 2d and a slot 25, the former receiving the screw 17 and the latter the ridge. In the base member is a groove 26 to register with the ridge.

The opening 24: and slot 25 reduce the cross section of the neck portion 21 of the blade and facilitate the flexing thereof into the desired curve in the razor. These openings may be of any desired shape and size, and can be arranged as in Fig. 8 hereinafter described.

By the formation of cutouts in the sides of the blade as shown at edges 22, a saving of material may be effected since a plurality of blades can be cut in staggered formation as shown by the dotted lines '27 in Fig. 8, indicating a fragment of the blank of another razor blade.

To cause most of the flexure on the blade to occur at the central or nec portion thereof, the razor may be correspondingly formed, so that the seat 13 forms angles of approximately degrees with the axis of the razor, as indicated by the handle 15. Thus the opposite seat portions form a total of lQO degrees. To afford a distribution of the stresses on the blade, the seat has a central portion 28 lying substantially at right angles to the axis of the razor. This seat portion 28 is of sufficient length to provide space for the simplified ridge and screw construction. From the central seat portion 28 extend in opposite directions seat portions 29 which may be substantially plane and slightly recess-ed at 30.

Both the base ann cover members of the razor may be made by molding, stan'iping, or the like, preferably the latter, for which purpose any suitable sheet metal can be used.

The construction of the cover member 1 as a stamping has an especial advantage since it can be inexpensively made and will have a minimum thickness, permitting the blade to lie closely tangential to surface being shaved. lVhere a cheap material is used, the cover member may be stiffened by the provision of ribs, flanges, or the like, and a particularly simple and compact construction is effected by forming marginal reenforcement elements such as flanges 31. Thus there may be a flange on each side of the cover member to extend downward and in engagement with the opposite side edges of the base member. These flanges may each be integral with the cover member and continuous therewith. in length. In assembling the razor, the base member may be easily set into the cover member between said fianges. the latter may perform the additional function of holding the said members against any lateral relative side movement. i

. "seesaw? the blade adjacent to the cutting edgesthereof, and the blade may follow a curve infthe razor, whereby it contactsthe cover member at 33 to predetermine the shape of'the curve and to stiffen the blade. e With the cover member beingmade of very thin metal as stated, and the outer surfaces 34thereoiplane, the latter may serve as guides for the operator in holding the razor in substantially tangential shaving position.

The ridge 23 may be made as part of the- 1 I v t p v 7 H cover member-14 oras aseparate part to'be. {to said axis,.the:seat haying .partsextending 'afiiXed thereto in a suitable manner. Thus the ridge may constitute an 'integral portion of a plate 35 extendi ngcrosswise of the cover" memberat the central part thereof and from flange to flange thereof. "To secure theplate; to the cover )member, the former may have" projections '36 to be press fitted or headed 1 overin corresponding openings 37,]in, thecover member. The screw 17 may aliord ad I ditional holding'engagementby, having'a shoulder coaction at38-with the plate.

In the construction ofthe razor, the resilience ofthe blade is available as a stiffening factor to render the cutting edges of the. blade stifi for apropercutting action, and such cut-. 4 H h I V v I 1 portion otthe blade, means, to .interconneetgfi ,the coverand' base membersincludi'ng a screwaandthe coverme'niber having apnea providedewith aridg egto engageinthe slot 7 j of. fi leblada thelplate being secured by the h foa ting action will be almostprecisely transverse to thehairs to avoid tearing or pulling thereon, and afford a smooth shave. It will be appreciated that there is anim portantrelation between thelength of "the blade and the curvature of the razor. This may be determined according to therelation of the length of an arc to the circumference; according to geometry.

However, arcs of varying angularity may be employed, al-v though they ought in every case tov be sufii cient for the reception of the handle there-L v, v v xpositezends guards for the cutting edges of between, since the razor must be light and compact. Furthermore, the degree of curvature to which the blade may be subjected must be considered, including thequality ofrthe steel and the construction'of the blade.

In Figs. 7 and 8 is shown a modified form of the invention, 'in which the construction maybe substantially as. hereinbefore de scribed, but the blade 39 has a transversely.
