One of the major objects of the present invention is to provide a superior safety razor and blade thereforwhereby a user m-ay readily and easily ascertain whicheutting position of the blade will provide a fresh shaving edge. 7 w

Another object of the present invention is to provide a Superior a etr j p an hlas e h refor constructed and arrangedwhereby persons having P 9 yes 9 R 9 P P0 1 1 3 ye: sight but in dim light may readily locate the desired cutting position of the bladewith respect to the safety razor proper.

With the above and other objects in view; as will appear to those skilled in the art from the present disclosure, this invention includes all features in the said disclosurewhich are novel over the prior art.

In the accompanying drawings, in which certain modes of carrying out the present invention are shown for illustrative purposes:

Fig. 1 is an elevational view of a safety razor including a blade and embodying the present invention; 7 V w Fig. 2 is a top or plan view thereof k Fig. 3 is a view mainly in longitudinal section on the line 33 of Fig. 1 and partly in elevation; H W

Fig. 4 is a sectional view taken on the line 4-4 of Fig. 1 but on a larger scale; h u v Fig. 5 is a perspective view of the outer clamping-member detached; r h

Fig. 6 is a similar view of the inner clampingmember together with its handle and tightening-- member; r no Fig. 7 is a face view of a; double-edge r azo .rblade suitable for use in the safety razor shown in the preceding figures Y J Fig. 8 is a sectional view similar to Fig- 4; but showing a modified form of the outer clampingmember; 7 Fig. 9 is a perspective viewof the 61111811613111.13- ingnember of the structure show-n in Fig. 8;

Fig. 10 is a face view of another form of doublesafety razor of the well known Gillette type which in thefo'rm ,shown includes an outer clamping-member Ill, a complemental inner clamping-ineinberl l, and a tubular handle 12.

The tubular har'idle 12 projects rigidly downwardly from the central portion of the inner clamping-member Il above referred to and the latter in effect constitutes a head for the said handle I2. The outer clamping-member IB' is provided centrally with 2. depending stem I3 whichis externally threaded at its lower end and which is adapted to extend downwardly into the tubular handle 12, as is' indic'ated in Fig. 3. The said outer clamping-member IB' is also provided on each of the respective opposite sides of its stem lil with two similar locating-Jugs I l-l4 which are adapted to extend downwardly through suitable apertures l5l5 in a wafertype razor-blade IS farmed, as usual, of highgrade steel. The said locating-lugs I l-l4 after passing through the apertures l5l5 in the razorblade [6 (Fig. 7) pass dewnwardly through apertures H-I'I formed in the inner clampinge l-.,,. j

In a manner common in the art, the razorblade [6 is located between the under surface of the outer clamping-member l0 and the upper surface of V the inner clamping-member It and m y be tight he d t e etiti n. referred to by means of a tightening member l8. v v

The main portion of the tightening-member 18 above referred to is extendible upwardlyinto the tubular handle l2 andis internally-threaded, as indicated in Fig. 3, to threadedly cooperate with the threaded lower end of the stem I3 of the outer clamping-member lfl A r U The razor-blade iii previously referred to is provided adjacent each of its four corners respectively with apertures i911), 2i and 22. Any given one of the said apertures is adapted, when the razor-blade is in position between the clamping-memb'ers wand ii to registerwith eprnbined punchout-and-sight openings 2% and 2d re; spectively formed in the clamping-members. It) and II adjacent eimilar corners thereof. The combined punchout-and- sight openings 23 and 24 just referred to are notonly in registry with e c ethe b e t nd. mr t lrih tsfi he respectiveelampin memibers which they are formed. as is especially well-shown in Fig. 4.

Usually, and as indicated in Fig. 7, the various surfaces of the razor-blade such as Is are marked with numerals, since in common practice it is customary to consider an identical edge as being a different edge when the blade is turned over. Thus, the blade 56 is provided with four designations respectively 1, 2, 3 and 4, as is indicated in Fig. 7. This feature is, as noted, common in double-edge razor-blades.

The razor-blade H; has its respective apertures 19, 20, 2! and 22 each filled with a body of nonmetallic and readily displaceable material providing punchout areas or members 25. The said punchout areas or members may be formed, for instance, of cellulose acetate, cellulose nitrate, polyvinyl chloride or any other suitable synthetic or natural resin having the characteristics of normally remaining in place in its given aperture and of being readily punctured or displaced.

The nonmetallic displaceable material of which the punchout areas 25 are formed is not transparent but translucent so that while light will pass therethrough the actual presence of the members 25 may be readily perceived which would not be the case were the same to be completely transparent.

Furthermore, and in the preferred mode of carrying out the present invention, the respective bodies 25 of synthetic material in the apertures I9, 20, 2! and 22 will be diiferently colored with respect to each other. Thus, the four bodies of nonmetallic displaceable material 25 in the blade #6 may be respectively translucent and colored red, blue, yellow and green.

One mode of utilizing the present invention would be for the user of the razor to insert and clamp a fresh blade like it between the clamplug-members ill and H and then by means of a toothpick, pencil or other instrument either totally displace or puncture the particular punchout member 25 which happens to be in registry with the combined punchout-and- sight openings 23 and 24 in the respective clampingmembers it and II. Before punching out the body as just described, the user could peer through the openings 23 and 24 by holding the razor up to the light to ascertain whether or not he was starting with the number 1 shaving edge, which in the present instance would be indicated by the red coloration of the particular punchout member 25 (in the aperture I9) which at the time is registered with the said openings 23 and 24.

After using the first edge, the user of the razor could, on the next occasion, install the blade HS in such manner that the aperture 2e was in alignment with the openings 23 and 2t and if upon inspection the aperture proved to be vacant, the user would then know that he was re-using a previously used edge.

Thus, by having the openings 23 and 24 respectively extending completely through the clamping-members l and M not only is the punching out or displacement of the punchout member 25 rendered convenient but the user may sight through the said openings by holding the razor up to the light and thus rapidly and surely ascertain whether or not he has installed a blade in the razor in such manner as to provide a fresh cuttin edge.

The structure of Figs. 8 and 9 The structure of Figs. 8 and 9 employs the same inner clamping-member H and its associated features as was illustrated in the preceding Figures, but the outer clamping-member I0 is replaced by a similar but slightly altered outer clamping-member 26. The clamping member is provided with a tubular punch 27 which is adapted to extend into the combined punchoutand-sight opening 24 in the inner clampingmember I l as is indicated in Fig. 8.

When a blade such as I6 is mounted upon the upper surface of the inner clamping-member H and the outer clamping-member 26 is applied thereover, the tubular punch 21 may be forced through the selected one of the apertures l9 to 22 inclusive to displace the punchout-member 25 therefrom. The opening through the tubular punch 21 provides a sight-opening which takes the place of the sight-opening 23 of the previously described outer clamping-member 10.

The razor-blade of Figs. 10 and 11 In Figs. 10 and 11 is illustrated a slightly modified form of razor-blade which may be utilized in place of the razor-blade I5 previously described. The razor-blade 28 is formed with four apertures respectively designated by the reference characters 29, 3B 3! and 32 and respectively corresponding to the previously described apertures 69, 20, 2! and 22.

Instead of providing inserts of nonmetallic synethetic material as was the case with the razor-blade l6 previously described, the razorblade 28 has adhered to one or more of its faces two strips respectively designated by the reference characters 33 and 34. The said strips are formed of the same type of material as has been previously described in connection with the features 25.

The razor-blade 28 above described may be substituted for the blade IS in the razors previously described and the particular areas of the respective strips 33 and 34 overlying the various apertures 29, 30, 3! and 32 provide the displaceable aperture-closing means or punchout areas similar to the means 25 before described.

The structure of Fig. 12

In Fig. 12 is indicated a single-edge razor-blade generally designated by the reference character 35, and having one edge sharpened as at 36 and its other edge provided with a clip 31 in a manner usual in the art. Adjacent its respective opposite ends the blade 35 is provided with one of two apertures 38 and 39 respectively covered or closed by bodies 40 and 41 of nonmetallic material similar to the material described in connection with the body 25 previously described.

The razor-blade 35 may be utilized in a Gem type or other suitable razor designed for the handling of single-edge blades and in which razor the respective clamping-members are provided with combined punchout-and-side openings similar to the features 23, 24, or 21, 24 previously described.

The invention may be carried out in other specific ways than those herein set forth without departing from the spirit and essential characteristics of the invention, and the present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein.
