Application January 11, 1956, Serial No. 558,577

2 Claims. (CI. 3063) This invention relates to a safety razor having a single unit cutting range adjustment.

An object of the invention is to provide an eflicient safety razor whereby the user can secure a satisfactory shave, whether he is accustomed to a tender or tough shaving.

Another object of the invention is to provide means in a safety razor which cooperates with the blade thereof to control the shaving by the operator so that excellent results are obtained.

A further object of the invention is to provide a novel control means which includes what might be styled a cam action for obtaining excellent results irrespective as to the type of beard on which it is used.

With the foregoing and other objects in view, this invention comprises certain novel constructions, combinations, and arrangements of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the drawings:

Figure l is a view in side elevation of a safety razor constructed in accordance with this invention, while Figure 2 is a sectional view taken along the line 22 of Fig. 1, as viewed in the direction indicated by the arrows.

Figure 3 is a vertical, central sectional view taken on line 33, Figure 2, and looking in the direction of the arrows.

Figure 4 is a vertical, central sectional view somewhat similar to Figure 3, but showing the adjustable parts as they appear for shaving tough beards.

Figure 5 is a horizontal sectional view taken on line 5-5, Figure 3, and looking in the direction of the arrows.

Figure 6 is a perspective view, greatly enlarged, of the control tension device.

Figure 7 is a detail fragmentary view of the bowed member and a part of the auxiliary frame.

Referring to the drawings by numerals, 1 designates the handle of the safety razor, on the inner end of which is fixedly mounted the primary frame 2. The primary frame 2 is provided at its outer end with a substantially right-angled lip or flange 3 against which one side of the blade 4 bears, Fig. 3. The blade 4 is flat throughout its length and is provided with the usual cutting edge.

The primary frame 2 is provided on its inner edge and at its ends with inwardly bent lugs 5 between which the auxiliary frame 6, Fig. 2, is positioned. The primary frame 2 is provided with a small tongue 7, Fig. 3, that extends through an aperture 8 in the auxiliary frame 6. The primary frame 2 is also provided with upstanding lugs 9, Fig. 2, against which portions of the auxiliary frame 6 bear. Therefore, it will be seen that the auxiliary frame 6 practically seats down between the lugs 5 and 9. The auxiliary frame 6 is provided with an upstanding flange 10. Therefore, it will be seen that the blade 4 is positioned between the parallel flanges 3 and 10.

The auxiliary frame 6 is provided with a spur 11, Fig. 7, that fits in the notch 12 of the bowed member 13.

On the end of the bowed member 13 opposite to that provided with the notch 12, a suitable aperture 14, Fig. 3, is provided through which screw 15 extends. Screw 15 is threaded through a hollow rivet 16 having a threaded bore 17. The head 18 of screw 15 is provided with a portion 19 that has a circular groove 20 therein, for the reason hereinafter described.

The auxiliary frame 6 is provided at its ends with upstanding lugs 21 under which are positioned the primary fingers 22 of the control tension device, Figure 6. Registering with the lugs 21 are spring-like lugs 23, Fig. 1; the lugs 21 and 23 constitute sockets into which fingers 22 are seated.

The control tension device (Fig. 6) comprises a bar 24 that has the primary fingers 22 on the ends thereof. The fingers 22 are off center of the ends, as clearly shown in Figure 6. By this structure, a cam action is obtained when using the device. Welded to the bar 24 are two parallel arms 25, which arms are connected at their outer ends. On these arms 25 are inwardly extending auxiliary fingers 26. These fingers 26 normally ride in the circular groove 20 of screw 15. Therefore, when the screw 15 is in its innermost position, Fig. 4, the bar 24 is furtherest removed from the blade 4, while when the screw is in its outermost position, the bar 24 will be in its innermost position (Fig. 3) close to the cutting edge of the blade 4, allowing of a close shave.

The bowed member 13 is normally positioned between the arms 25. The bowed member 24 performs the function of a spring and exerts pressure upon the auxiliary frame 6, holding the frame in an eflicient seated position upon the primary frame 2. By reason of the auxiliary frame being held in a comparatively rigid position upon the primary frame, the control tension device, Figure 6, is efficiently positioned for the adjustment thereof with respect to the kind of shave the operator desires.

The flanges 3 and 10 constitute jaws between which the blade 4 is held. In other words the primary frame 2 has jaw 3 at its outer end and the auxiliary frame 6 has jaw 10 at its outer end.

Referring particularly to Figure 7, the lug or spur 11 prevents any sidewise movement of flange or jaw 10, thereby assisting in stabilizing the structure, by reason of said spur fitting in the notch 12.

While I have described the preferred embodiment of the invention and illustrated the same in the accompanying drawings, certain minor changes or alternations may appear to one skilled in the art to which this invention relates during the extensive manufacture of the same, and I, therefore, reserve the right to make such changes or alterations as shall fairly fall within the scope of the appended claims.

What I claim is:

1. In a safety razor, the combination with a primary frame provided with a primary jaw, an auxiliary frame seated on said primary frame, said auxiliary frame provided with a jaw adjustably mounted close to said primary jaw, said jaw of the auxiliary frame provided at its ends with upstanding lugs, said jaw of the auxiliary frame also provided with spring-like lugs registering with said upstanding lugs, said upstanding lugs and spring-like lugs constituting sockets, a bar provided with fingers on its ends fitting into said socket, and manually operated means on said primary frame and connected to said bar, whereby the position of the bar can be adjusted with respect to said primary and auxiliary jaws.

2. In a safety razor, the combination of a primary frame provided with a jaw, an auxiliary frame supported by said primary frame and provided with a jaw, a control tension device mounted on said head comprising a bar having primary fingers on its ends, said fingers oif center of the ends arsid Bar'na 'ngaging an fir't'iafi to provide a cam action thereagainst, parallel arms connected to said bar, said arms provided with inwardly extending auxiliary fingers, a "shrew mounted on said primary 'frainQ-said screw-provided Witha circular gram;
