Application January 31, 1957, Serial No. 637,453
1 Claim. (Cl. 30-741) This invention is concerned with safety razors for shaving of the type in which a flexible, replaceable blade is supported in position between two separate members that are afiixed to a holder.
The razor herein to be described has a unique feature in that there are three (3) separate cutting edges for shaving and one (1) short cutting edge for removing a beard beneath the nose of the person using the device.
Heretofore, razors have appeared on the market with two (2) cutting edges which are for the purpose of giving extra time and use of the blade.
It is a principal object of the within invention to provide a safety razor which has facilities for providing a medium, heavy, and a light cutting edge on the same blade which are separate from each other.
It is another object of the within invention to provide a safety razor that has the feature of a small cutting edge to cut away whiskers and hairs beneath the nose.
It is yet another object of the within invention to provide a razor blade holder that hasa novel geometrical shape that lends itself for speedy cutting'of whiskers from the face and the body.
It is still another object of the within invention to provide a safety razor assembly that is inexpensive in the cost of manufacture and yet is of excellent and high efliciency.
The above and other objects are attained by the use of a three sided razor blade mounted in a razor assembly in which the head itself appears to be triangular, except for a short, fiat cutting surface between two of the three larger sides.
Reference is made to the following specification and the accompanying drawing in which:
Figure 1 is a side elevational view of the razor blade assembly.
Figure 2 is a top plan view of the razor blade assembly looking down on Figure 1.
Figure 3 is a view of the inside portion of the cap, looking up into the head of Figure 1.
Figure 4 is a sectional view taken along line 4-4 of Figure 3.
Figure 5 is a view of an enlarged section along the line 5-5 of Figure 2.
Figure 6 is a top plan view of the razor blade itself looking down upon it.
Figure 7 is a top plan view of the razor blade support member.
Figure 8 is an exploded perspective view of the entire razor and blade assembly.
In Figure 1 the entire razor and blade as assembled is shown. The razor blade assembly has a handle portion 1 and a bottom of the handle 2. Above the handle portion 1 is a top tapered portion 3 which lies beneath the blade support 6. The blade support 6 is shown in detail in Figure 7. Above the blade support 6 is the razor blade itself 11, which is shown in detail in Figure 6 and which can be seen clearly in the exploded view of hired States Patent 0 Figure 8. Above the razor blade 11 is the head 13. The head 13 has a pyramid top point 21.
In Figure 8 there are screw threads 5 on the screw portion 4 of the handle 1. In the support 6 there is an opening 128 into which the screw portion 4 passes. It is also to be noted that in the blade 11 there is an opening 12 also through which the screw portion 4 passes. Beneath the head 13 there is a cylindrical opening 12H having threads 5A for receiving the threads 5 of the screw portion 4. It is by rotating the handle portion 1 so that the screw portion 4 threads into the opening 12H which is afiixed to the-head 13 that the three parts, the cap 13, the razor 11, and the support 6 are held securely together. The razor blade 11 has besides the central opening 12, other openings which align the razor blade 11 in the proper position on the support member 6. The opening, for example, 18B, fits around the protrusion 18 in the cap 13. The opening 19B similarly fits around the protrusion 19 of the cap. 13. Similarly does the opening 20B fit around the protrusion 20 in the cap 13. The protrusions 20, 19, and 18 pass through the openings in the razor blade 11 as just mentioned and also pass through the complementary openings in the support shown in Figure 7. That is to say, that the opening 188 lies proximate to opening 18B in the blade 11 and both fit around the protrusion 18 in the cap 13. Similarly do the openings 19S and 20S fit around the protrusions 19 and 20 in the cap 13 and lie beneath, of course, the openings 19B and 20B in the razor blade 11.
It is to be noted in the view of Figure 2 that the letters, L, H and M appear on the surfaces of the cap 13. It is to be pointed out that the razor cutting edges opposite these letters are for heavy (H), light (L), an d medium (M) cutting. The surface on the head 13 opposite H is indicated on the cap 13 as 9H and on the support as 98 and on the razor blade itself as 9. The surface on the light edge indicated at L has an edge 10H on the cap, an edge 108 on the support, and a cutting edge 10 on the razor blade. Opposite the medium cutting edge are the edges H on the cap, 88 on the support, and 15 on the razor blade 11. There is a short edge indicated on cap 13 in Figure 2 as 78. This surface has beneath it a cutting edge 7 on the razor blade 11 and beneath that, an edge 78 on the support 6. This particular cutting edge 7 is small and is designed to fit beneath the nose of the person being shaved. It is, of course, small and may be utilized to cut hair in areas which are difficult to get to with the larger length of blade.
The cap 13 is not fiat but has inclined planes reaching down from the top pyramid point 21. The surfaces which are inclined from point 21 are all triangular. Upon inspection of Figure 2 it can be seen that the surfaces marked M, H, and L are separate triangles and that the surface marked 14H is also a triangular surface. The cap 13 and the support 6 pressing together cause the razor blade 11 to have tension at its central areas of the various inclined surfaces. These surfaces are indicated on the razor as 14 for the surface opposite the cutting edge 7; 15 for the area opposite the cutting edge 8; 16 for the area opposite the cutting edge 9; and 17 for the area opposite the cutting edge 10. The numbers in the drawings on the cap are similar and proximate to the areas indicated in the razor blade. However, these numbers have an H thereafter. They are, 15H on the area opposite the cutting edge 8H; 16H on the area opposite the cutting edge 9H; 17H on the area opposite the cutting edge 10H; and 14H on the area opposite the cutting edge 7H. Similarly, on the support 6, the numbers are similar and proximate those of the blade that have the letter S thereafter. The cutting edge has 'the""triangularsurface 168; the cutting edge 85 is opposite the triangular area 158; the cutting edge 78 is opposite the triangular area 148, and the cutting edge 108 is opposite the triangular area 178. There is in the support 6- a sleeve 22 which can be seenin' a cross-section in the view of Figure 5. This sleeve 22'is complementary to thereceptacle' 121-1 and assists in-the alignment of the support6,"the razor blade 11, and the'cap 1 3.
- In operation, it is necessaryto assemblethesupport 6, therazor-blade11,'and the cap 13 as indicated in the exploded-view of Figure 8. 'Because of the openings 12S, 12H through the center ofthe support 6, and the razor blade -11,with the screw 4 passing therethrough into'the cylindrical -opening 12H, and because of the 'protrusions 18, 19, and 20 already mentioned, in the cap which pass through--the openings complementary "thereto'in therazor blade 11 and'-the support 6;-and
because of thesleeve'22, the parts align themselves automaticallyupon being placed one over the'other as'shown in Figure 8 and itis only-necessary for the user of the razor to turn the handle 1' so that the threads 5 on the screw portion'4 will engage the threads SH Within the receptacle 12H and'tie in its threads 5 therein.
' in the razor blade 11 it is only necessary that edge-7 be used at right angles against the skin. As pointed 'out, the edge 7 lends and adapts itself to getting into places which "are-small and difiicultto reach-with the longer cutting edge.
A pressure is exerted by the cap 13 on the blade 11 against the support 6 causing the blade 11 toconform to the pyramid shaped the cap 13.
Dimensions in the drawing have been exaggerated to teach more clearly the within invention. Changes in certain of the detailed structure are contemplated without departing from spirit and scope of the within invention.
-I-Iaving thus described my invention, I claim:
