SAFETY RAZOR.

Application filed August 6, 1920. Serial No. 401,648.

To all'whom iii-"mag concern:

Be it known that I, LEON M. BUYUKAS, a subject of the King of Greece, and a resident of Grantwood, county of Bergen, and State of New Jersey, have invented certain new and useful Improvements in Safety Razors,

set forth in the following specification.

This invention relates to safety razors. The object of the invention is to provide a structure which shall be compact, simple, convenient for use and at the same time, one in which all parts of the blade-holding structure are inter-connected to form an integral whole, even when the structure is opened for the removal of the blade and with all the parts so arranged that the blade contacting surfaces are free from obstructions so as to permit of ready cleansing, particularly for the removal of rust stains.

More generally the object of the invention is to improve safety razors of the type employing a flexible blade.

The above will be pointed out more particularly in the accompanying claims which are directed to the illustrative embodiment of the invention, described in the following specification in connection with the accompanying drawings, which form a part hereof, and in which drawings like characters designate corresponding parts in the several figures.

In the drawings, Fig. 1 is a left side elevation of the assembled structure;

Fig. 2 is a front elevation of the assembled structure;

Fig. 3 is a right side elevation;

Fig. 4 is a plan view of the structure with the blade-holder open;

5 is a cross section of the assembled structure;

Fig. 6 is a plan view of the assembled structure ShOWiIlg theblade clamped in position;

Fig. 7 is a section through VII VII of Fig. 6; and

Fig. 8 is a plan view of the blade employed.

A guard member A of substantially rectangular outline is arranged to be mounted on any suitable handle 1, detachably connectable therewith as through the means of the threaded stud 2; The blade engaging face 3 of the guard member A is preferably cylindrically convex, as is best indicated in Figs. 1, 3 and 7, although these figures show the surface 3, conforming to the shape of a line a smooth curved cylindrical surface, it is to be understood that the expressions cylindrically and cylindrical in this specification are use to denote such a surface as is generated by an element moving parallel to itself and following either a curved line or the sides of an angle or a combination, lines and curves. The desired functioning shape for the surface 3 is such that a flexible blade B mounted upon said surface 3 may be flexed or dished from its central line downward at both edges 5 and 6 :so that the edges 5 and 6 approach the guard fingers7 and 8 which form the side terminal'edges of the guard member. A.

A clamping blade holder C of a length to span the blade B and the guard A and having a concave cylindrical under surface 9 .to. fit over the surface 3 and for direct engagement with the blade B is suitably hinged at one end to the guard A. A preferred embodiment for the hinging is a link 10, hinged to the cars 11 of the guard A by hinge pin 12, and to the blade holder C by the hinge pin 13, secured in the ears 14. By this arrangement the link 10 is free to swing in the notches 15 and 16. A notch 17, symmetrically positioned and otherwise similar to notch 15 is symmetrically hinged to the other end of guard member A A link 18 has hinged to it, by hinge pin 19 a double cam 20, operable by a thumb piece 21,'while the link 18 itself is hinged to ears 22 straddling notch 16 on the blade holder C by the hinge pin 23. The pins 12, 13 and 23, it should be noted, are located sufficiently back from the blade engaging surfaces 9 and 3 so that the links 10 and 18 may be swung completely clear of these surfaces, as indicated in Fig. 4, so that a brush or cloth may be wiped over these surfaces to remove all rust stains without encountering any obstructions while, at the same time, the links 10 and 18 may serve as positioning means for the blade B- by cooperation therewith through the notches 24c and 25. So far as the structure of the guard and clamping member is concerned, they are both free from all obstructions to interfere with cleansing by a flat brush or polisher. The blade B positioned upon the guard A so that its notches 24 and 25 correspond in position with the notches 15 and 17, may be clamped in position by swinging the holder C up and overthe'blade. The link 18 is pressed into the notches l7 and 25 while the link 10 enters the notches 15 and 24, serving to canter the blade B. A manipulation of the finger piece 21 serves to operate the cam 20 to clamp the blade holder C so as to flex the blade B and hold it firmly upon the guard member A.

It should be noted that even when the structure is opened, to remove the blade, the guard C is held fixedly assembled to the guard A by the link-10 as likewise are all the other parts. This prevents the loss of a part in the use of the structure. Furthermore, the links 10 and 18, which cooperate with the blade B in the notches 24 and 25 for positioning the blade, are readily swung clear of the cylindrical blade-engaging surfaces 9 and 3 and there are no projecting pins or posts otherwise to obstruct the wiping of these surfaces.

What I claim and desire to secure by United States Letters Patent is:

A safety razor comprising a guard member having a cylindrical blade-engaging surface free from obstructions to prevent cleaning; a blade holder for ing and binding a blade upon said guard member having a surface configuration complementary to said cylindrical clamp- 25 blade-engaging surface of said guard member; a hinge link hinged at one end to said serving as means for positioning a blade;

and a clamping hinge link for connecting the other ends of said guard member and blade holder being hinged to the end of one of said members to swing clear of its bladee'ngaging surface and beingprovided with disengageable clamping means for the end of the other said member and serving, when in operative position, as means for positioninp; a blade.

In witness whereof I have signed my name to this specification, this 2nd day of August,

L. M. BUYUKA S.
