JOH/Y 15 5554i X Q W 3,015,159 COMBINED SAFETY RAZOR BLADE AND GUARD ASSEMBLY John E. De Baun, 335 Marshall St., Ridgewood, NJ. Filed Aug. 10, 1959, Ser. No. 832,518 1 Claim. (Cl. 30-47) The present invention relates to razors, and more particularly to a combination safety razor and blade combination.

It is well known that safety razors are constructed so that a portion of the razor can be opened and a blade inserted therein. The use of the blade alone for shaving has often been attempted, but, either the safety features are lost, or else the user cannot shave with the blade. Although many attempts were made to provide a blade which could be directly used for shaving, still retaining the safety features, because of the dilficulties and disadvantages, none, as far as I am aware, was entirely successful when carried into practice commercially on an industrial scale.

It has now been discovered that a blade assembly, i.e., a safety type razor blade assembly can be provided which can be used directly with a handle for shaving, of simple and inexpensive construction.

It is an object of the present invention to provide a simple and inexpensive combined razor blade and guard assembly, which together with an appropriate handle can be used directly for shaving.

Another object of the invention is to provide an inexpensive throw-away type of razor blade which can be used for shaving.

The invention also contemplates providing a method for manufacturing an inexpensive type of razor blade assembly or rather a razorless shaving blade assembly.

With the foregoing and other objects in view, the invention resides in the novel arrangement and combination of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

The invention will appear more clearly from the following detailed description when taken in connection with the accompanying drawings, showing by way of example, a preferred embodiment of the inventive idea.

Generally speaking, the present invention contemplates a razor and blade assembly, comprising the combination of a flat sheet of the usual safety razor blade length and of about double the width of the usual safety razor blade, having an aperture in the center thereof, preferably in rectangular form, i.e., which forms a rectangle when flat, occupying about just enough room for the insertion of a handle therethrough, or a little wider permitting the passage of water and soap therethrough. Said sheet is folded at slightly more than a right angle along the lengthwise center thereof forming two lower wings, each lower wing being again folded at an angle more than a right angle, forming an upper wing which in turn is folded back on itself in a hairpin turn to form a blade. The size of the upper wing and the blade folded thereon occupies in one plane a space somewhat smaller than the size of the lower wing.

For a better understanding of the invention, reference is had to the accompanying drawings in which:

FIGURE 1 is a perspective view of the razor and blade assembly with the handle attached, contemplated herein, and ready for use;

FIG. 2 illustrates in greater detail the razor and blade nited States Patent lee assembly as well as the handle shown in FIGURE 1 by showing a top unassembled View thereof;

FIG. 3 depicts a bottom view of the razor and blade assembly alone; and,

FIG. 4 depicts a perspective View of the handle alone.

In carrying the invention into practice, it is preferred to employ the device depicted in the foregoing described drawings. The razor and blade assembly shown therein comprises a sheet of metal 10, which is initially flat, the dimensions of which are between about 2 to about 3 inches long by about 2 to about 2 /2 inches wide, of rectangular shape. Said sheet of metal 19, when flat has an aperture or central opening 19 at the center thereof, advantageously likewise of rectangular shape, and about 1 to about 1%. inches long by about to about inch wide. Said flat sheet is folded down a center line 12 thereof parallel to the length to provide opposing wing formations with lower wing portions 11 slanted towards each other at an angle of between to about 120 approximately, at their juncture, said lower wings curve gently so that there is no sharp intersection of the two planes formed by the wings but rather a. gradual curve where said wing formations meet. At a point about between /s to /2 inch from the centerline 12 on each of said lower wing portions 11, there is a second gradual curve bend 13 forming an angle of between 100 to approximately in said lower wing portions 11, and forming upper wing portions 14. At approximately from to up from said second fold, said upper wing portion is folded back on itself in a hairpin turn 15 to form the blade 16. Preferably, at this hairpin turn 15, the blade 16 is connected to the upper wing portion 14 by a series of teeth 17, parallel openings or apertures 18 being provided between the teeth to allow for the passage of soap and water. Likewise, the aperture 19 should be constructed so that the handle 21 will not fill up the entire opening 19, but on the contrary, it is preferable to allow for room for the soap and water to escape. As is evident from the drawing, aperture 19 runs lengthwise along the upper wing portion 14. Therefore, along said upper wing portion 14, and advantageously towards the center of said aperture 19, engageable holding means 20, or one of a pair of such means should be provided so as to cooperate with corresponding holding means 25 on the handle 21.

The handle for the razor and blade assembly may preferably be made of plastic having some resiliency; thus said handle 21 need only comprise one sheet of plastic bent to form a hairpin turn 23 so as to have two sides 22, and flanges 24 on the sides bent outwardly of a size to enter aperture 1% and rest against upper wing 14-. Holding means 25, corresponding to holding means 211 on upper wing 14 should be provided on the flanges 24. Thus, to use the handle with the razor-blade assembly, all that is needed is to press on the sides 22, insert the flanges 24 through aperture 19 and have the respective holding means, i.e. 20 on the upper wing, 25 on the flange into engagement, and the razor and blade assembly is ready for use.

It is to be observed that the razor and blade assembly herein contemplated is easily manufactured with simple machinery. Thus, aperture 19, teeth 17, recesses 18 and holding means 20 all can be made in one stamping operation. Lower wings 11 and upper wings 14 can all be shaped in a die, and likewise blade 16 can be turned at hairpin turn 15 either in the same or in a subsequent die operation. Preferably, the blade edge 16a is sharpened prior to the stamping and folding operation.

In this way, there is provided a two edge blade, i.e., razor and blade assembly with an attachable handle which constitutes an entirety, or a complete razor which is simple, more efiicient and longer lasting. When disposing or discarding the double edge dull blades, the Whole assembly excepting the handle is rejected or discarded by a simple pressure on the hande 21 which releases the razor and blade assembly from the handle. And in a similar way, hand pressure will admit or connect another assembly 10. The blade is bent at both edges so as to function or duplicate the action of a carpenters wood plane. Furthermore, the blade angle is such that the blade will more readily cut the hair or heard.

The razor and blade assembly herein contemplated can be made and supplied at the same cost as conventional razor blades. The simple plastic handle can be supplied either with a package of blades or separately. To sharpen the blade edge 16a, it is only necessary to contact the blade edge with a fiat stiff back conventional leather strap and push downwards or forward, and avoid pulling the blade as this would cut the strap. The blade should be lifted from the strap for the return stroke and again pushed. The assembly 10 can readily be made from a stamped out moderately thin steel with sharp edges. The handle likewise can readily be made by forming a U- shaped plastic having a spring like tendency and having curved or turned out ends which can look into the razor and blade assembly.

Although the present invention has been described in conjunction with preferred embodiments, it is to be understood that modifications and variations may be resorted to Without departing from the spirit and scope of the invention, as those skilled in the art will readily understand. Such modifications and variations are considered to be within the purview and scope of the invention and appended claim.

I claim:

A combined razor blade and guard assembly formed of a sheet of razor blade material having a bend along a center line providing wing formations, each of said wing formations having a lower wing portion and an upper wing portion bent inwardly and upwardly along a bend line parallel to the center line, said'wing formations being cut away to provide a central opening, each of said upper Wing portions being folded outwardly and downwardly upon itself and having a cutting razor edge on its end running parallel to the center line, each of said upper wing portions having vertically-extending parallel openings extending through the bend of the upper Wing portion upon itself and providing thereby a series of teeth along the bend of the upper wing portion and said central opening being adapted to receive a detachable razor blade handle.
