'7 Claims. (01. 30 94) This invention relates tonew and'useful improvements in a blade for safety razors.

This invention proposes the construction of a blade for a safety razor or other similar razor which is characterized by the fact that it has more cutting edges than the conventional safety razor blade without requiring more material.

Still further the invention particularly proposes increasing the cutting edges of a standard two edge blade so that it has four cutting edges, without an increase in-the material from which the blade is constructed.

Still further the invention contemplates an arrangement whereby a plurality of flat narrow blades with cutting edges at the sides are positioned in the horizontal and associated with a means for holding the blades as a unit for engagement into a safety razor so that certain of the edges (the outer edges) of the blades are exposed for use, and whereby the blades may be adjusted so that the other cutting edges are repositioned to constitute the outer edges and then are exposed for use.

Still further the invention contemplates the arrangement of flat narrow blades with cutting edges at the sides and positioned parallel to each other, and end elements cooperatively associated with the blades for holding the blades as a unit for engagement into a safety razor so that the outeredges are exposed for use, and wherein the blades may be adjusted so that the other cutting edges constitute the outer edgesexpo'se'd for use.

As another object of this invention it is proposed to associate end elements with theends of a plurality of flat narrow blades having cutting edges at the sides in a manner so that the blades may beheld with either of the cutting edges disposed outwards, and wherein'the mem-' ber itself is adapted to be associated'witl'i the standard parts of a safety razor, that is, the cap plate and the guard plate for the purpose of holding the blade as a unit within the safety razor ready for use.

Furthermore as another object of this inven-- tion an arrangement is proposed whereby a memher is adapted for association in a safety razor, a plurality of flat narrow blades with cutting edges at the sides are arranged in the horizontal, 50 and cooperative means arranged upon the member and blades for holding these parts as a unit simulating a conventional blade for a safety razor.

The invention also proposes a provision wherer by" the flat narrow blades previously mentioned 5 are equipped with handles by which they maybe readily adjusted from one to the other of their positions of exposing either of their edges.

Still further the invention proposes the construction of articles asmentioned which are simple'and durable and which may be manufac- 5 tured and sold at a reasonable cost.

For further comprehension of the invention; and of the objectsand advantages thereof, reference will be had to the following description and accompanying drawing and to the appended 10 claims' in which the various novel features of the invention are more particularly set forth.

The blade for safety razors according to this invention comprises a plurality-of narrow-flat '5 blades 10 with cutting edges II at the sides and positioned parallel to each other, in the horizontal and associated with a means for releasably holding said blades as a unit for engagement into a safety razor so that the outer edges are exposed for use. More particularly the means referred to according to the form of the invention illustrated in Figs. 1-4 comprises end elements [2 having dove-tailed projections.l3 adapted to ene gage in similar cutouts l4 formed in the ends of the blades for holding the blades as a unit.

The cutouts M are extended through the thickness of the blades so that the end elements [2 may be assembled by just sliding the element into position so that the tongues l3 engage the openings Hi. When the blade is engaged in the safety razor the cap plate and guard plate of the safety razor will prevent the blades ID from becoming disconnected from the end elementsl2 in that these parts will be held against relative up and down motion.

The elements 12 are so constructed to facilitate the engagement of the blade within a conventional safety razor. For this reason, a fork shaped projection I5 is arranged upon the inner sides of each of the elements l2. These fork shaped projections l5 are adapted to engage the conventional central rib formed upon the cap plate of the safety razor. This rib is schematically illustrated by the dot and dash lines I6.

The dot and dash lines I! illustrate the cap plate 3 and 4.

of a razor. This cap plate is shown formed at the corners with projections 18, as is a construction of a popular brand of razor blades sold on the market at the present time.

The end elements l2 are so arranged that they projections 18 engage against the endsv thereof and in this mamier the blade is safely and. securely held within the razor. In Fig; 1 the blades ID are shown having their edges numbered I, 2, With this arrangementv records may be kept as to the number of times each of the edges are used so that the most satisfactory services can be obtained. from the blades. As illustrated the blades H] are shownwith one of their edges disposed upon the outside. These blades may be disengaged from the end elements and turned around through 180 and then reengaged in place so that the edges which werepreviously towards the inside are now disposed towards the outside and ready for use when the blade is engaged into a safety razor.

In Fig. 3 a sectional view hasbeen illustrated.

in which the cap plate I! is shown coacting with the guard plate I9 holding the blade according to this invention in place. From this illustration it will be readily understood that only the outer edges of the blades ID are in position for use. A.

feature of this invention resides in the fact that without adding any additional material to that now generally used for the blades of a safety razor, two additional edges are obtained and thus the operative life of the razor doubled.

In Fig. 5 a slight variation of the invention has,

been disclosed in which the blade is substantially identical to the form previously described except for the fact that end elements are used which distinguish from the previous end elements in having large projections l5 upon the inner sides arranged so as to engage in a different type. of safety razor. The large projections 15. are formed with several curved portions 20 and 2| arranged to produce openings for the passage of. studs. This. razor blade is adapted for use in safety razors equippedwith studs. projecting from.

the cap plate through the guard plate as has been a very popular design in the past. There are large numbers of these razors still held by the public and with the arrangement disclosed in Fig. 5 the blade according to this invention may be used in that particular type of safety razor.

In Figs. 6 and 7 another variation of the invention has been disclosed inwhich the blade is equipped with a member 22 having several openings 23 for receiving the various studs which are projected from the cap plate through the guard plate of razors now on the market. This form of the invention distinguishes from the previous form in the arrangement of transverse end portions 24 on the member 22 and of a greater thickness then the member 22, and arranged to adjustably hold the blades In. More particularly the ends of each of the portions 24 are formed with projections 25, constituting fork constructions for engagement upon both sides of the blade I!) simultaneously. Located between the fork projections 25 and upon the end portions 24 there are projections 26 adapted to engage into niches 21 upon the blades I0 for the purpose of holding the blades against displacement.

this arrangement it is possible to reverse the blades whenever desired by merely flexing the blades to cause them to bend and allow. the disengagement.

In Figs. 9 and 10 another variation of the invention has been disclosed which is very similar to the previous form except for the fact that this blade is formed with a holder 22 having a longitudinal slot 28 in addition to the openings 23 to adapt it to more than one type of safety razor now on the market. The member 22' is provided with end portions 24 formed with openings 29 adapted to receive small tongues 30 projecting from the ends of the blades It]. With this arrangement it is necessarythat the blades Ill be slightly flexed at the centers to disengage the tongues 30 from the openings 29 for the removal of the blades. With this arrangement it is possible to reverse the blades as previously described. The tongues 30 are of flat construction engaging in the round openings 29, so that the blades are firmly held from falling out but may be rotated without removing the blades from the end portions 24.

In Figs. 11-13 inclusive, another modified arrangement of the blade according to this invention has been disclosed which distinguishes from the previous type in the provision of a member 22 having cutouts at the ends producing a. fork construction 32. The inner faces of this fork construction are formed with small longitudinal recesses 33 for receiving a shank in'a manner so that the shank may snap into place. With this arrangement the blade [0 is provided, which has tongues 34 projecting from the ends. These tongues are permanently engaged with studs or socket elements or shanks 35 adapted to engage the fork 32 and snap into the recesses 33. The studs 35 are formed with heads 36 adapted to normally be disposed outside of the portions 24 in a manner so that the blades'lll may be reversedwithout their removal from the holding'member, by merely gripping the heads 36 and turning the heads to cause turning of the blades.

In Fig. 14.an assembly of the cap plate Hand the guard plate I 9 has been disclosed inconjunction with, a blade. according. to. this; invention.

With this arrangement the blades [0 must be snapped into and out of position. With The blade is shown to comprise the blade portions in which are disposed in between the cap plate I! and I9 and which have their ends slightly projecting and the enlarged end portions 24 previously described. The purpose of this view is to illustrate the manner in which the end portions 24 are located outside of the area of cap plate and guard plate so that the construction and assembly of the device may be readily understood.

It is to be understood that the blade holders may be made of any suitable material, such as metal, composition, etc. and that the blades may be either sold with the said blade holders or separately for filling the blade holders.
