4 Claims. (Cl. 30-66) This invention relates to safety razors and more particularly t-o inexpensive disposable razors using the injector type blade. Specifically, the invent-ion relates to a simplified construction and improvements in the bladeattaching means.
It is well known that for sanitary reasons razors are extremely personal toilet articles which are not ordinarily exchanged between users. Heretofore, therefore, travelers who found themselves Without their own personal razors were forced to either purchase new razors or engage the services of professional barbers whenin need of a shave. Both alternatives were objectionable for many reasons including the expense involved, particularly when it is noted that the purchase of a razor is oftentimes not inexpensive. For these and many other reasons the need for an inexpensive disposable safety razor has been long felt. However, attempts to furnish such an inexpensive razor, to my knowledge, have met with little success for the reason that razors which were sufficiently inexpensive to warrant their use for relatively few times, were incapable of affording satisfactoiy and safe use.
Finally, a further object is to afford a safety razor 0 simple, inexpensive construction yet sturdyand eflective for the purposes intended. Inits simplest form the razor comprises a handle member formed with a blade-supporting portion at the top thereof. A simple clip-on member is adapted to retain the blade on the supporting member; integrally formed portions of the various members serving as guard devices. The entire razor may be. molded or otherwise formed from inexpensive plastic materials or portions may be made from metal or other suitable materials.
With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel features of construction, arrangement and a combination. of parts hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed'out in the appended claims, it being understood that various changes in the form, proportion, size and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.
For the purpose of facilitating an understanding of my invention, I have illustrated in the accompanying drawings a preferred embodiment thereof, from. an inspection of which, when considered in connection with the following description, my invention, its mode of construction,
It is therefore an important object of this invention to provide a safety razor of such design that all of the objections mentioned hereinabove are satisfactorily overcome.
Another object is to afiord a safety razor which may be entirely constructed of inexpensive plastic.
A further object is to provide a safety razor having a removable head with elements adapted to cooperate with other portions of the razor to efiectively secure a razor blade in operational position within the razor.
In some of the razors which were introduced in an attempt to alleviate the condition mentioned previously, disposable razors were afforded with a blade permanently mounted therein. Obviously such a razor could be used only for the duration of the razor blade edge. As soon as the edge became dulled, the razor was rendered ineffective and a new razor was required. Oftentimes, such a razor could be used for not more than one or two shaves. It is therefore another important object of this invention to provide an inexpensive disposable razor which may be used over a considerable length of time and for a relatively large number of shaves. An object relating thereto is to so construct the razor that the blade may be removed and changed whenever the need arises.
Still another object is to provide simple clip-on means for assemblying the razor blade with the razor.
Still a further object is to afford a two-piece razor which maybe readily disassembled for cleaning purposes and as readily assembled when desired.
Yet another object is to provide a safety razor in which metal guards may be completely eliminated so that the skin of the user need not be irritated by contact with metallic materials. It is well known that the skin of many individuals is often-times allergic to or in other ways irritated by contact with the metallic pogtions of razors.
assembly and operation, and many of its advantages should be readily understood and appreciated.
Referring to the drawings in which the same characters of reference are employed to indicate corresponding or similar parts throughout the several figures. of the drawings:
Fig. l is a perspective view of a safety razor embodying the principles of my invention;
'Fig. 2 is an exploded plan view of the razor as viewed in the position shown in Fig. 1 of the drawings and with a portion broken away to better illustrate certain details of construction;
Fig. 3 is an enlarged fragmentary sectional view taken on the plane of line '33 in Fig. 1- of the drawings and viewed in the direction indicated; and
Fig. 4 is an enlarged fragmentary perspective view of the clip-on head member of the razor.
Turning now to Fig. 1 of the drawings, reference numeral 10 indicates generally a two-piece razor blade holder comprising a handle member 12 and a clip-on head member 14. The handle member 12 comprises a wide slightly-arcuate shaped strip 14, at least one side of which may be provided with spaced ridges or protuberances such as 16. These ridges afford gripping means for the fingers of the user.
The upper portion 18 of the handle member 12 serves as a blade-supporting member and is formed with an upstanding straight wall portion 20 adjacent a second straight wall portion 22, the plane of which is disposed substantially at right angles to the plane of the straight wall portion 20.
Between the two straight Wall portions 20 and 22 there may be formed a rectangular-shaped slot 24 extending transversely across the razor with the ends thereof defined by segments 26 and 28 connecting the straight wall portion 22 to the straight wall portion 20. Upwardly extending protuberances such as 30 and 32 are further provided at these points each with vertical faces such as 34, the function of which will become apparent as the description proceeds. One side of the slot 24 may be formed with a marginal detent or step-down formation such as 36. It will be noted that the straight wall portion 20 provides a straight inner surface 37 and that the top of the straight wall portion 20 is inwardly curved as at 38. A transverse groove as 40 may be formed in this the thickened portion42andthe opposite endportion 46; V
This straight wall portion 22 terminates adjacent a verti call'y' disposed member48, the plane of which 'is at right angles to the plane ofthe straight wall 'portion22 It will further be noted that the member s isspaced from the inner suirface 37 of the straight wall member 20. p h cutting means h zvrmar c mp i a blade such as 50 with its leadin'gedg'e 52 honed and sharpened to provide the shaving edgeofthe blade; This blade is positioned on the blade-supporting top surface of the straight wall portion 22 of the razor with its cutting edge 52 positioned over the slot 24 and abutting the vertical faces 34 of the protuberances 30and32.
Securing the; blade in the above-described position is the novel removable clip member 14 whichwill now be described in some detail; As illustrated in Fig. 4 'of the drawings it will be noted that the'clip 14 may be unitarily formed from any suitable material such as plastic,'wood; metal, rubber'and the like and resembles at least remotely a short but broad clothespin. Preferably the clip should be made from a material among whose properties should be included resiliency sufiicient to insure the proper functioning of the member. 7 v Essentially, the clip comprises a pair of wide prongs .56 and 58 integrally formed and protruding from a cylin drically-shaped shank portion 60. From the rear of the is less than the thickness of the portion 42, the prong returns to its unflexed position, leaving the clip securely.
positioned on the razor with the razor blade secured therein. 7 V
In operation the user merely grasps the handle member 12 of the razor and positions the head against the skin with the razor blade edge in close proximity to the skin.
Although the blade is held in a plane which is at a slight 1 angle to the plane of the skin surface, the movement of the razor is substantially parallel to the plane and contours of the face or skin surface. The protuberances 30 and 32 serve as guards asdoes the leading edge 76 of the slot 24.

shank 60 there may protrude a singlefinger-grasping member 62 which extends transversely across the entire width of the clip 14. The prongs 56 and 58 terminate at their inner ends in a vertically positioned straight wall 64'which, in cooperation with the inner surfaces 66. and 68 respectively of the prongs 56 and 58, provide a channel 70.
'When the clip'14 is placed in operational position on the razor, the blade 50 and the straight wall member 22 are positioned within the channel 70 in such a relationship that therbladeis securely and immovablyretained therein; the height of'the channel 79. being such that the blade and the straight wall member 22 are securely clamped therein. The clamping relationship is insured by the resiliency of the prongs 56 and 58. V
To insure the retention of the clip on the razor, the top surface 68 of the bottom prong 58 is formed in a reverse-curve, the shape of which is complementary to the shape of the bottom surface of the wall member 22.
It will be noted thatthe blade sup orting top portion of the razor is formed with sidewall members such as 72 which depend from the segments 26 and 28 and in thickness are no greater than the width of the segments. Hence,
the bottom prong 58 is somewhat narrower than the top Pr ng 6 and the ends thereof are indented inwardly sufficiently to permit the bottom prong tobe accommodated between the side wall members 72. So also the bottom prong 58 is somewhat shorter than the top prong 56. a
To assemble the razor the blade is first positioned on the blade supporting portion as described hereinabove and as'illustrated in Figs. 1 and 3 of the drawings. The clip 14 is'then grasped between the fingers of the operator and forced into operational position with a portion of the blades!) and the straight wall portion 22 positioned in the channel 70. As the thickened portion 74 or" the lower prong 58 is forced over the thickened portion 42 of the straight wall member 22, the prongs are flexed outwardly to enable the admittance of the blade and wall assembly within the channel. 'After the two thickened portions have passed over one another, the thickened portion of the prong moves to the intermediate portion 44 0f the member 22. Since, the thickness of this intermediate portion From the foregoing description and drawings, it should be apparent that my invention provides a simple, inex-. pensive, disposable safety razor which may beuscd coo-- nomically for a single shave and then disposed of or may be used for a number of shaves as desired. Detachable d clip means are provided so that the blademay be changed orthe razor disassembled for cleaning. The entire razor may be 'made from a non-irritating material, such as plastic or rubber, thereby completely eliminating all metal parts which might otherwise irritate the skin with the ex ception, of course, of the cutting edge of the razor blade. It should also be apparent that my shaving device,
although capable of disassembly, contains nomoving parts and readily lends itself to mass production with no assembling operations required.
It is believed thatmy invention, itsmode of construction and assembly, and many of its advantages should be readily understood from theforegoing without further description, and it should also be manifest'that while a' preferred embodiment ofjthe invention has been shown and described for illustrative purposes, the structural details are nevertheless capable of wide variation within the purview of my invention as defined in the appended claims. a 7
