This application is a substitute application for my application, Serial No. 215,755, filed June 25, 1938 now abandoned.

This invention relates to improvements in safety razors.

The main object of the invention resides in an inexpensive safety razor having a non-removable razor blade whereby the entire razor must be disposed of after the blade becomes too dull for shaving purposes.

Another feature of the invention is to provide a safety razor wherein the blade and its holder constitute a single unit which is simple and inexpensive of construction to enable its user to economically dispose of the entire unit after a limited number of shaves, thus eliminating the usual practice and annoyance of removing a used blade from its holder and replacing the same with a new one.

A further object of the invention is the provision of a safety razor unit in which the razor blade holder is constructed from a single blank of bendable metal.

A still further feature of the invention is the provision of a razor blade holder in which the handle thereof is constructed of a pair of winglike elements flexibly connected to the underside of the razor head to enable compact folding of the elements against the head for packing purposes, and which elements may be flexed outwardly and brought into confronting relation to handle forming position when the razor is to be used for shaving.

Other novel features of construction will be apparent as the following specification is read in conjunction with the accompanying drawings, in which:

Figure 9^a is a plan view of a modified form of blade.

Referring to the drawings by reference characters, the numeral 10 designates my safety razor unit in its entirety, the blade holder being constructed from a single blank of thin metal A shown in Figure 9 and the material from which the blank is formed being preferably of thin sheet steel or aluminum. The blank A is elongated in plan and is cut to provide a central rectangular shaped clamping plate 11 having spaced slots 12 arranged in longitudinal alinement. Coextensive with the ends of the clamping plate 11 are guard plate sections 13—13, the same being foldable against the underside of the clamping plate 11 on the transverse fold lines 14—14. Slots 15 are provided along the fold lines 14—14, the slots extending further into the guard plate sections 13 than they do into the clamping plate 11. The guard plate sections 13 are wider than the clamping plate 11 and arranged adjacent and parallel to the longitudinal sides of the guard plate sections 13, are rows of equidistantly spaced slots 16 and extending longitudinally through the slots are dot and dash lines 17 indicating lines of fold on which the side edges of the guard plate sections are folded. Struck out from the guard plate sections 13 and arranged in longitudinal alinment with the slots 12 are tongues or prongs 18. Coextensive with the guard plate sections 13 are wing like finger grip elements 19—19, the same being bendable on the perforated lines 20—20.

Having described the blank A, I shall now describe the manner in which a double edge cutting blade 21 of the “Gillette” type is associated with the holder formed from the blank. The razor blade 21 is placed flat against the clamping plate 11 with the longitudinal slot 22 of the blade in registration with the slots 12 of the clamping plate, while the reduced ends 23 of the blade projects over the slots 15—15. The longitudinal side edges of the guard plate sections 13—13 are folded under on the lines 17 which form spaced guard fingers 24 along the longitudinal sides of the guard plate sections. The guard plate sections 13 are next folded inwardly over the blade on the clamping plate 11 on the fold lines 14—14 which causes the reduced ends 23 of the blade to project through the slots 15. The prongs 18 are bent outwardly and inserted through the slots 22 in the blade and through the respective slots 12—12 in the clamping plate 11, after which the prongs are bent over the outer side of the clamping plate as clearly illustrated in Figure 7 which effects a tight clamping of the blade 21 between the clamping plate 11 and the guard plate sections 13—13. By reason of the prongs passing through the slot 22 of the blade and the extension of the reduced ends 23 of the blade passing through the slots 15—15, the blade is properly positioned with respect to the guard edges of the guard plate formed by the sections 13—13. When the sections 13—13 are folded inwardly, they meet to provide a continuous row of guard fingers 24 along the longitudinal sides of the razor head. The finger elements 19—19 are bent into shell-like shape in cross section as best seen in Figure 7, and each is formed with a concavity 25 to accommodate the index finger and thumb to effect gripping of the razor for use. For packing purposes, the finger elements 19 are folded flat against the under side of the razor head on the weakened fold lines 20—20 as illustrated in dotted lines in Figure 7 of the drawings.

From the foregoing description, it will be seen that I have provided a safety razor unit which is inexpensive of construction and relatively light in weight, and which may be used in the manner of an ordinary safety razor with the exception that the handle formed by the finger elements 19—19 is relatively short but is sufficient to enable the thumb and index finger of the hand to firmly grip and hold the razor when in use. Due to the inexpensive construction, the entire razor may be disposed of after the edges of the blade 21 become dull, thus eliminating the annoyance and loss of time in changing blades.

In Figure 9^a I have illustrated a modified form of double edge blade 21′ which may be used instead of the “Gillette” type blade 21 hereinbefore referred to. The blade 21′ is provided with a relatively large slot 22′, the end walls of which are centrally notched as at 23′ to receive prongs similar to those designated 18—18. With this type of blade, the slots 15—15 may be dispensed with for the ends of the blade 21′ fit within the confines of the ends of the head of the holder.

While I have shown and described what I consider to be the preferred embodiment of my invention, I wish it to be understood that such modifications thereof may be resorted to as come within the scope of the appended claims.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is:

1. A safety razor blank comprising a single elongated blank of bendable sheet metal which is cut to a shape and foldable on transverse lines to provide a central clamping plate, a pair of guard plate sections connected to the ends of the clamping plate section and foldable inwardly thereunder into end to end relation, said guard plate sections having guard teeth on the side edges thereof which extend beyond the plane of the side edges of the clamping plate, said clamping plate and guard plate sections being adapted to have a double edge razor blade interposed therebetween, bendable tongue and slot connections between said guard plate sections and said clamping plate for securing the same in clamping relation, and a pair of finger grip elements connected to the adjacent inner ends of the guard plate sections along lines of fold, whereby said finger grip elements may be folded flat against the respective guard plate sections for compact packaging purposes, and subsequently unfolded by bending them to a position at right angles to said guard plate sections into contacting engagement with each other when the razor is intended for use and by which the razor may be grasped and held by the thumb and forefinger of the user.

2. A safety razor as set forth in claim 1, in which the finger grip elements are provided with concavities which open outwardly when the finger grip elements are in finger grasping position.

3. A safety razor of the non-replaceable blade type comprising a clamping plate, a pair of guard plates underlying said clamping plate and having their respective outer ends integral with the ends of the clamping plate, a double edge razor blade interposed between said clamping plate and the guard plate sections, bendable tongue and slot fastening connections between said clamping plate and the guard plate sections, the tongues of the tongue and slot fastening connections passing through slots in the razor blade and bent against the clamping plate, and a pair of finger grip elements integral with and flexibly connected to the inner ends of said guard plate sections for compact folding thereagainst for packaging purposes, and for unfolding to a position at right angle to the guard plate sections when the razor is to be used for shaving purposes.

Anestis Foltis.
