SAFETY RAZOR.

Application ,flled March 31, 1928. Serial No. 266,867.

character.

1'0 vide a safety razor device with few parts that may be readily cleaned or renewed and capable ofguarding against slashes of the face when used rapidly.

A still further object of this invention to provide means for quickly removing the blade from the razor device to the end that the blade may be readily seated securely in position upon the razor and in this manner serve to deliver a clean cool shave.

Another object of my invention is to provide in a device of the kind set forth means for effecting fine adjustments of the blade in the blade holder part of the safety razor.

Still a further object of this invention is to provide an improved guard for the blade of the razor outfit whereby this guard is located in advance of the blade edge instead of underneath the same. I

\Vith the above and other objects in view my invention consists in the combination, arrangement and details of construction disclosed in the drawings and specification and then more particularly pointed out in the appended claims- In the drawings, wherein similar reference characters designate similar parts throughout the several views,

Figure 4 is a bottom plan view of one section of the razor, and

Figure 5? is a plan view of the other section of the razor.

Referring to the, drawings, which are merely illustrative of my invention, a handle 10 threaded as at 11 is formed upon a concavo-convexrazor blade carrier which tapers from small as at 12 to large as at 13, where by the arc distended by the large end is struck on a smaller radius than the small end so that the corner of the part 13 curves around further downwardly than the end designated at 12, providing a diagonal edge 13'. The blade is made of ribbon steel and is narrow, being designated 14, havin the sharp cutting edge 15 and the en wise notches l6. l

There is provided a tubular razor blade holder 20 having formed thereupon the diagonally disposed slot 21 and having formed upon diametrically opposite points the holes 22, 23 thru whichthe handle 11 of the blade carrier may project. 19 designates the point where handle 10 is secured to razor blade carrier A. l e

The blade carrier A is also formed upon its concave side with the endwise notches 17 and 18 designed to receive the pins 24 and 25 disposed at the ends of the blade holder 20 to be more particularly referred to hereinafter. This blade holder 20 in a plane with the diagonal slot or slit 21 is formed with a diagonal countersunk seat 26 whose shoulder edge appears clearly in Figure 10 where it will also be seen that the blade seating and holding pins 24 and 25 project outwardly from the blade holder. Extending in the same direction as the slot 21 is a guard consisting of the comb elements 27 spaced.

under the blade edge 15 when all the parts are properly assembled. L

It will be noted that as the seat 26 is d1sposed diagonally of the holder 20 and is arcuate in cross section that one end where pin 24 is disposed will extend down farther than the other end where pin 25 is disposed. 3O designates the knurled handle of the device at the upper end of which is the internally threaded stem 28 having the threaded bore 28'into which screws the screw 11 of handle 10 of the blade carrier A. The blade 14 is taken and its notched ends 16 seated around the pins 24 and 25 which centers and trues the seating of the blade flat upon the curved arcuate seat 26 of the blade holder 20. Figure 9 shows how this blade seats shows one end of the blade snugly fitting the pin end 25 of .the holder 20 while the opposite end of this blade 14 has its edge spaced out of contact with the ad acent curved surface of the holder. Now when all the parts of the razor are assembled in proper order and relation as shown in Figure 12, the handle or post 10 of the carrier A Wlll be introduced into the holes 22, 23; the blade 14 will be seated against the pins 24, 25, the threaded portion 11 of this post Wlll be then entered in threaded relation into the bore 29 of the stem 28 of handle 30; the handle 30 will now be rotated to screw home the threaded portion 11 of the handle 10, thereby causing the lip 13 ,of the carrier A to extend down so as to engage the end of the razor blade farthest removed from contact with the holder 20, as at 13' as the rod 11 is screwed home the razor blade is being flexed and curved to the outline of the holder and thereby set the edge and adjust the blade as may be desired for shaving purposes. The tighter the screw handle 30 v, is screwed home the more securely will the blade be clamped in position. It will now be seen from Figure 13 that the cutting edge 15 of the blade is spaced above the guard comb 27 opposite the slit 21 and the device is then ready for use. Figure 11 shows the ultimate curvature of the razor blade.

I have devised a modification of. the razor blade device shown-in Figures 1 to 5 inclusive. Here it will become obvious that the handle 18' is secured into one section 13 of the razor device, the other section being designated 14. The sections are of the same shape being U-shaped on concave in cross section hinged together as by means of the hinge knuckles 12 and 27 thru which knuckles the pintle 12' extends to unite movably thetwo sections.

Section 13 carries the diagonally disposed razor blade l6in any desired manner and also carries the handle stub 17 by means of which the sections may be opened and closed against the tension of the spring 20 secured at one end by fasteners 21' to section 10 and having a free bearing 19 against the other section, as shown in Figure also having corresponding holes formed therein for the pins 20 to project in. A leaf spring 26 is attached to the cover plate 22 and has a coil wound around the pintle 25'; this arrangement allows the cover plate 22 to be lifted with the pins 20 out of engagement with the blade holes 19 against the tension of this spring 26' when it is deslred to remove the blade for replacement purposes. When both sections are closed the blade is ready for use. I claim all variations coming within the scope of the appended claims. 1
