2,421,205 Razor Errol F. Kingsley, Multnomah County, Oreg. Application June 1, 1945. Serial No. 597,067. 10 Claims. (Cl. 30—49)

One of the objects of this invention is to provide a simple form of safety razor of the wafer blade type.

Another object of this invention is to provide a razor of the class described which will have an improved blade-holding principle forming the cutting edge into a curved line, being a combination of pressure upon the ends of the wafer blade and the lower central portion thereof as indicated by A and B in Fig. 6 of the drawing. This overcomes any possibility of movement or chattering of the blade in relation to the razor during shaving. It improves the cutting property of the blade and also permits it to better conform to the surface of the skin over which the razor is passing.

A third object of this invention is to provide a guard having grooves or teeth that are diagonal in relation to the guard itself. This feature permits the guard to create a greater friction upon the skin under the blade, thereby stretching it tighter and improving the cutting efficiency of the blade. This form of guard also has a tendency to move the skin sidewise at approximately right angles to the direction of the razor stroke, thereby further improving the shaving quality of the razor.

A fourth object of this invention is to provide a handle that has a definitely enlarged portion forming a natural grip for the thumb and fingers.

I accomplish these and other objects in a manner set forth in the specification and accompanying drawing, in which Fig. 1 is a front elevation showing the parts in an open position; Fig. 2 is a front elevation of the razor in a closed or working position; Fig. 3 is a side elevation of Fig. 2; Fig. 4 is a plan of the guard member; Figs. 5 and 6 are for illustration of the principle of combination of pressures that hold the blade, with Fig. 5 showing the parts in an open position and Fig. 6 showing them closed with pressure applied at A and B. Fig. 7 is an enlarged diagrammatic view of the head of the razor.

Fig. 8 is a diagrammatic top view of the head of the razor.

Fig. 9 is a diagrammatic view of a portion of the arm 12 of the razor.

Similar numerals refer to similar parts throughout the several views.

Referring in detail to the drawing, there is shown a handle 10, on one end of which are disposed the curved arms 11 and 12, which are substantially the same width as is the diameter of the handle 10. The ends of the arms 11 and12 are joined by the arcuate plate 13 and flat back 14.

Secured to the arm 11 at the hinge 15 is a rectangular guard member 16 having one straight side 17 and an arcuate side 18 which constitute a guard for the razor and are spaced somewhat away from and inside of the edge 19 of the curved plate 13. The end 20 of the guard member 16 is straight and is adapted to occupy the notch 21 in the arm 12 when the device is in a closed position. To further expedite the clamping action that is holding the blade 24 and the positioning of the guard 16, there is provided a spring 22 on the side of the arm 12, said spring bearing against the end 20 of the guard member 16 and in turn against the blade 24 to create pressure at point A of the blade.

Secured to the arcuate side 18 of the guard member is a clamping jaw 25 which is curved to conform with the interior of the plate 13 and is fixedly joined by the legs 26 to the side member 18 of the guard 16. When the razor is closed, the clamping jaw 25 creates pressure at the point B of the blade 24. The blade 24 is substantially one-half of the width of the ordinary wafer blade and is held firmly between the members 13 and 25 and by the member 22 and the arm 11.

While the arms 11 and 12 are integral with the handle 10 and form substantially an are at the upper end of said handle, the inner face of the arm 12 from its point of joinder with the curved plate 13 for a distance of approximately of an inch below said plate is parallel with the plane of the axis of the handle 10 so that the distance between the point on said arm 12 of an inch below the curved plate 13 is considerably further to the point where the guard member 18 is hingedly connected with the arm 11 than the distance from the point where the arm 12 connects with the curved plate 13 to the point where the guard member 18 is hingedly connected with the arm 11. This construction permits the insertion of the wafer blade 24 while the clamping joint 25 is open as shown in Fig. 1.

The wafer blade is of such a length as to permit it to be readily placed upon the clamping jaw 25 when in its open position as shown in Fig. 1, but is sufficiently long so that when the clamping jaw 25 is closed, the end 20 of the guard member 16 will press the spring 22 in and against the end of the wafer blade 24 and thereby compress the wafer blade 24 by the contact of one end of the blade with the inner edge of the arm 11 and contact of the other end of the blade with the spring 22.

The closing of the clamping jaw 25 with the attached guard member causes the end 20 of the guard member so pressing against the spring 22, to seat itself in the notch 21 of the arm 12 and hold the same in said locked position, thereby causing the end pressure upon the wafer blade 24 between the arm 11 and the spring 22. This spring 22 is of piano wire welded to the arm 12 in such a position as to permit the same to be compressed beyond the inner surface of the arm 12 upon closing the jaw 25.

Upon closing of the clamping jaw 25 the same applies initial pressure on the under side of the blade 24 and limits the movement of the blade 24 between the element 13 and the jaw 25, however, the blade 24 is held firmly in its arched position limited in its upper arch by the plate 13. The pressure which holds said blade 24 firmly in its arched position is provided by the pressure of the spring wire 22 on one end of the razor blade 24 and the abutting of the other end of the razor blade 24 against the opposite side of the frame of the razor just below the plate 13.

The spring wire 22 has an outwardly extending offset just opposite the notch 21 in the arm 12. Upon closing the jaw and guard member the end 20 of the guard member fits snugly against the arm 12 and having enough give to the guard member to cause this snugly fitting and still permitting the same to be readily closed, but when the Jaw member is completely closed the end 20 of the guard fits into the notch 21 and by its contact against the offset in the spring wire 22 causes said spring wire 22 to press in against the end of the blade 24.

It can be seen from the foregoing that I have provided an extremely simple and effective form of razor which has the minimum number of parts, all of which are joined together, and the closing and opening movements are made by a simple hinge action. It will be noted that the line of the arms 11 and 12 is inclined somewhat with relation to the axis of the handle 10, and that the angle of the face 13 is less than 90 degrees with relation to the arms 11 and 12.

These angles and parts may be modified to suit the ideas of the individual manufacturer without departing from the spirit of this invention.
