RAZOR.

Application filed June 15,

This invention relates to razors, and in particular to that form of razor known as a safety type. The invention has for an object the provision of a razor wherein the blade is held at correct shaving angle without the necessity of the operator attempting to hold the blade at such angle.

Another object is the provision of a razor which will permit the blade to be readily placed within the razor holder or ejected therefrom without entirely disconnecting the blade holder parts.

Another object is the provision of a razor which is sanitary in that there are no parts which will allow moisture or germsto collect, andto this end the razor is so formed that it may be readily cleaned withina minimum of time. Another object is the provision of a razor which will hold a blade properly to obtain best shaving results.

Another object is the provision of a razor which will shave either a substantially flat surface or a curved surface and using the same blade.

Another object is the provision of a razor wherein the handle member thereof is so arranged as to securely lock the razor blade and razor holder together.

Other objects include inexpensiveness of construction, adaptability for general use and service, and general superiority.

With the above and other objects in view, the invention cons'sts in the novel and. useful provision, formation, construction, association and relative arrangei'nent of parts, members and. features, all as shown in certain cmbodimcnts in the drawing described gen erally and more. particularly pointed. out in claims.

Corresponding parts in all the figures are designated by the same reference characters.

Referring with particularity to the drawing, the improved razor is designed as an entirety by A, and such razor includes as elements a handle a, blade holders Z) and c, and a blade (Z, all of which elements may be used in practicing one embodiment of the invention.

The handle or includes a knurled hand-engaging portion 1 which is reduced as to diameter at 2, the reduced portion being provided with a head 3 which is provided with a curved periphery or ball-shaped part. This head portion is axially bored and screw-threaded as indicated at at. The said razor handle will act to hold one or the other of the blade holdcrs Z) or c. The blade holder Z) includes two parts 5 and 6, the said parts cooperating to clamp the blade (.1 therebetween. The part 6 has a greater transverse width than the part 5, and such part is commonly known as the guard-piece, being provided with acomb edge 7. The part 6 is likewise provided with two spaced bores 8 and 9, and with a central slot 10, there being a flanged member or raised portion 11 upon said member 6 and bounding the slot 10. This member 11 acts as a bearing member for the head 3 of the handle when the blade holder members 5 and 6 are cooperating to hold. a blade. The part 5 of the blade holder is provided with two spaced guide studs 12 and 13 superimposed upon a surface of said blade holder, and likewise with a stud 14 which is bent transversely as indicated at 15 so as to provide two portions 16 and 17 angularly related with the portion 16 screwthreaded at 18. In general practice the blade (Z is sharpened along one longitudinal edge only, and when it is desired to place the blade between the blade holders 5 and 6 it is only necessary to lay the blade, say, on the member 5, as indicated in Figure 7 so that the unsharpened edge of said blade will abut against the guide studs 12 and 13, whereupon the member 6 may be laid upon the blade, the said guide studs being passed through the openings 8 and 9 and the threaded stud through the slot 10, after which the handle 1 is screwthreaded to the threaded stud 15, as indicated in Figures 1 to 4 inclusive. The handle plus the stud 15 acts as a locking means for locking the blade holders together. The head 3 by having a curved periphery or a substantially hall-shaped periphery will be in part received within the confines of the slot 10 and engage a portion of the side walls of the raised part 11 on the guard-piece 6.

It is evident upon inspection of the drawing that due to the form of th screw-threaded. stud 14L the razor holder is held at an angle to the handle 1, and this angle is assumed to be the one best adapted for shaving purposes, so that it is only necessary to press the blade holder lightly against the surface of the part to be shaved, said blade holder being held at a proper angle so that the blade (Z is most effective. Furthermore, it will be readily appreciated that neither guard-piece has any obstruction or openings which are difficult to clean, and which are likely to form possible breeding places for germs. As a matter of fact, by slightly unscrewing the handle the blade can drop from between the blade holders and by holding the blade hol der under hot water followed by shaking the blade holder, it is properly cleansed without the necessity of extensive wiping, such as now required by safety razors wherein all the parts must be separated or that type of safety razor in which the blade holders are hingedly connect ed. However, our safety razor doesnot stop at a single feature,'that is, by providing a blade holder adapted for shaving flat surfaces, but is so constructed that surfaces difficult of access, such as under the arm-pits, at the chin, under the nose, etc., may be as easily shaved as a substantially flat surface, such as a side of the check. The blade holder 0 includes two members and 21, the member 21 being of the convex concave type the convex surface being adapted to have the blade bear thereon. This ineu'iber 21 is in all details the same as the member 6, with the exception of the longitudinal curvature given the same. The same holds true for the holder 20 which is of the convex-concave type, and in all details sim ilar to the holder 5, save in one particular, that is, the threaded stud adapted to be ennotch 22 will maintain the said blade slightly flexed, as indicated in Figs. 12 and 14. The guard 21 is then placed over the blade when positioned as in Fig. 12, so that the studs 12, 13 and 1a are passed through the openings 8, 9 and 10 of the member 21, whereupon the handle may be secured to the threaded stud 15, as before. Thus, the blade will be flexed to correspond to the curvature of the blade holders, all as indicated in Figs. 9 and 10. As before stated, places difficult of access with the ordinary flat blade may be readily shaved when the blade is so flexed. The present razor will then be distributed with blade holders of the type 7) and 0 adapted to have a common handle member 1, and a pack of blades of the form (Z, and it will be readily appreciated that the razor just described is universal in its adaptability.

' From the foregoing description it will be seen that we have presented in the present safety razor, in addition to a universal type,

of razor, one whereinthe head of the handle has a two-point engagement with the blade holder, in that the handle has screw-threaded engagement with the stud 13, while a second portion, namely, the curved surface of'the head 3 of said handle is in engagement with the bearing surface or flanged part 11 bounding the slot 10. Furthermore, this contact zone is slightly spaced from the zone of engagement between the head and the said stud 15, as indicated in Figure 4 at 40 and 41. As a result we provide a razor in which the blade holder and the handle are securely locked together, a feature of importance, as it prevents a turning of the blade holder relative to the handle when the razor isin use, and which oftentimes r sults in serious cuts.

It is obvious that various changes and modifications may be made in practicing the invention, in departure from the particular showing of the drawing, without departing from the true spirit of the invention.

Having thus disclosed our invention, we claim and desire to secure by Letters Patent:

1-. Improvements in safety razors, including a handle, ablade holder carried by said handle, said blade holder comprising two separable members, one of said members being provided with a threaded stud, said handle being formed to receive said threaded stud to hold the blade holder to said handle, said threaded stud being formed with a notch portion, and whereby when the blade is received between said blade holders a portion of said blade is received within said notch.

2. Improvements in safety razors, including a blade holder comprising tWo separable members, one of said members being provided at its rear edge with two spaced guide studs, and a bent screw threaded stud, the other of said blade holders being formed with two spaced openings adapted to permit the passage of the guide studs therethrough, and

with an elongated slot to permit the bent stud to pass therethrough, there being a raised 10 bearing surface member surrounding said elongated slot.

In testimony whereof, we have signed our names to this specification.
