Y. Application August 5, 1936, Serial No. 94,405 1 Claim. This invention relates to safety razors, an ob ject of the invention being to provide a safety razor having an improved construction and ar Ul rangement of guard and cap constituting clamp ing means for a double edged safety razor blade between them, said parts being capable of adjust ment so as to accommodate various thicknesses of blade and permit ñexing of a thin blade and securely clamping a rigid blade without ilexing the same. , Another object is to provide an improved con struction of guard and cap which insures a proper positioning of the blade and the retention of said blade in proper position under all conditions. A further object is to provide a safety razor of this character which can be readily taken apart, thoroughly cleaned and reassembled. With these and other objects in View, the in vention consists in certain novel features of construction and combinations and arrange ments of parts, all of which will be more fully hereinafter described and pointed out in the claim. In the accompanying drawing 25 . Figure 1 is a View in side elevation of my im proved safety razor with the parts assembled for use; Fig. 2 is a view in transverse section through the center of the head of the razor and a portion 30 of the handle, the rest of the handle being shown in elevation; - Fig. 3 is a top plan view of the razor shown in Fig. 1; ' Fig. 4 is a view in longitudinal section through CIJ 5 the center of the head of the razor; Fig. 5 is a perspective View of the razor cap; Fig. 6 is a plan View of the bla-de; ' Fig. 7 is a perspective view of the guard; Fig. 8 is a view similar to Fig. 2 showing the position of the cap and guard with a rigid or non-flexible blade clamped between them. My improved safety razor comprises three main parts, namely, a guard I, a cap 2, and a handle 3. 4 represents a double edged safety razor blade clamped between the cap 2 and guard I, and said cap is formed centrally with a screw (Cl. 30-68) commonly employed in the art, it is to be noted that as a matter of fact both the members I and 2 constitute guards as they are provided along their longitudinal edges with teeth 9. . The guard I is formed on its upper face at 5 both ends with a pair of spaced lugs IU, and ex tending from these lugs to the side edges of the guard are transversely extending webs II, and between the lugs I Il at the extreme ends of the guard, recesses I2 are formed in the guard. The cap 2 is provided in its ends with spaced recesses I3 to receive the lugs Ill, and between these re~ cesses I3 longitudinally extending bars I4 are provided which extend beyond the ends of the cap and at their extremities are provided with downwardly extending fingers I5 which are adapted to be positioned in the recesses I2 in the guard. The blade 4 is of the double edged type and is provided in its ends with spaced recesses I6 which receive the lugs I0 of the guard, and the blade is of such a length that it i'its nicely between the webs II at the ends of the guard. In other words, the blade is con iined and held against lateral or longitudinal movement relative to the guard and cap'by rea son of the fact that the lugs I0 project through the recesses I6 of the blade and the webs II conñne the ends of the blade and, furthermore, when the cap is screwed down tightly upon the blade its bars I4 and fingers I5 resting in the , recesses I2 further confine the ends of the blade so that the blade is incapable of displacement from its normal proper position relative to the guard and cap when the parts are properly as sembled. 35 The blade 4 must of course have a central opening 6, as above deñned, to receive the stud 5 of the guard, and where the blade is a ñexible one in addition to this opening 6, longitudinal slots I'I are formed centrally of the blade and merging into the opening 6. It is to be under stood, as above stated, that my improved razor is adapted to clamp not only a flexible type of blade, which is given an arched ilexed formation between the cap and guard as shown most clearly in Fig. 2 of the drawing, but it is also within theV threaded stud 5 which projects through open scope of the invention to provide a rigid or non- ` ings 6 in the blade 4 and through an opening ‘I in the guard I and engages internal screw threads 8 in the tubular handle 3 so that when flexing blade which is also securely clamped be the handle is screwed tightly against the guard the cap 2 will be drawn downward to securely clamp the blade 4 between the cap and the guard. While I employ the terms cap and guard to indicate the parts of the razor head such as tween the cap and guard as shown in Fig. 8 of the drawing. 50 While I have illustrated and described what I believe to be the preferred embodiment of my invention, it is obvious that various slight changes may be made with regard- to the form and ar rangement of parts without departing from my 55 2,117,850 2 invention, and hence I do not limit myself to the precise details set forth but consider myself at liberty to make such changes and alterations as fairly fall Within the spirit and scope of the claim. I claim: of the guard, the blade and the cap both hav ing recesses in their ends to receive the webs, integral bars at the ends of the cap between the recesses therein, said bars extending beyond the ends of the cap and adapted to rest between A razor head including a cap and a guard the lugs on the guard, fingers at the ends of the adapted to clamp a blade between them, spaced lugs integral with the guard at the central por bars adapted to overlie the ends of the blade between the cap and guard, said guard having tions of both ends thereof, webs extending from 10 the lugs to the sides of the guard, the surface between the lugs being flush with the surface recesses in its ends receiving the fingers. 10 JOHN FRANCIS OÃ’MALLEY.
