Application April 7, 1939; ScrialLNoAli (Ci. Sii-454) S'Ciainis.

My. invention relates to razors and relates particularlyto-those razors wherein the blade isremovable from the razor holder. f

Heretofore, razor blades of both the flexible and rigid type have beenused in holders. However, the blade holders require careful adjustmentito tensionfor to hold-the blade in position. Whenaaman employing the razor is in a hurry or` does` not make the proper adjustment, the razor blade will not properly cut the hairs on a mans face.

Therefore, it is an object of my invention to provide asafety razor with an automatic blade tensioning unit.

Another object of'my invention is to provide in-.a safety razor a device which will enable the razor blade to be quickly removed or rapidly installed inits proper position.

AnotherA object of my invention is to provide a razor blade and razor blade holder which can easily` be cleaned.

Anotherv object of my invention is to provide a razor blade holder which will hold a non-lex ingthin blade.

Other objectsof my invention are to provide animproved. device of the character described, that is easily and economically produced, which issturdy in construction and which is highly efficient in operation.

With theabove andrelated objects in view, my invention consists in the following details of construction and combination of parts, as will be morev fully understood from the following description, when read in conjunction with the accompanying drawing, in which:

Fig. 1 is a fragmentary side elevational View of my inventionshowing a razor blade holder with a razor blade in place.

Fig. 2 is a fragmentary side elevational view of the razor blade holder showing the razor blade in position to be inserted.

Fig. 3 is a topV View of the razor blade holder showing the razor blade in place.

Fig. 4 is a top View of a modication of my invention showing an assembled blade in the holder.

Fig. 5 is a side elevational view of Fig. 4.

Fig. 6 is a top view showing a modiiied razor supporting member holding a blade that has an inclined cutting edge.

Referring now in greater detail to the drawing, I show a razor with a hollow cylindrical handle, generally designated as A. A blade rest is generally designated as B. The blade rest consists of a substantially flat surface slightly inclinedin relation tothe handle, and attached to one sideof the blade rest is a cylindrical member, generally designated as C, which interfits with the handle A. The blade holder or rest is oi' the safety type variety having a plurality of serrations inthe front edge it. It has two small endstops l2 and il?. at each end in a position to receive the cutting edge oi the blade. The stops i2k andli hold the blade in a` predetermined positionin the razor holder.

A razor bla-de, generally designated as D, has its cutting edge it lie over the serrations in or- .er to cut into the beard without cutting the face oi the user. The blade is positioned back of the serrations, as above described, and the serrations prevent the blade from cutting into the flesh of the user.

ApluralityA of side holding. and overhanging lugs ifi and i3 prevent the side movement of the blade and also retainthe blade in position in the holder by providing reaction against the locking pin, hereinafter described.

The rear end 22 of the blade, which comes substantially over the center line of the handle, is contacted by a bevel or cyiindrical lock pin, generally designated as E. The lock pin is beveled at its upper end Eiland is adapted to go up against the rear edge 22 of the razor blade in order to hold the razor blade securely in cutting position.

TheV cylindrical portion C' of the blade holding member B has an inclined opening or inclined slot 24 therein at its lower end, which serves to receive a pin 23 that is fixed to and f arranged to move the cylindrical portion 28 of the blade holding member longitudinally within the handie of the razor when the handle is rotated in relation to the blade holder member. A spring 25 surrcundsthe lower end of section 28 and impinges on the bottom 29 of the handle A and the lower end of the Xed blade cylinder C. Thus, the tendency of the spring 25 is to force the razor pin E in a downward direction.

The blade locking pin E is comprised of two

cylindrical sections

26 and 28 which are connected by virtue of a spring 30 which is between the cylindrical sections 26 and 2B. The lower section 28 of the locking pin E also is securely fastened to the handle A whereby rotation of the handle constitutes rotation of the lower cylindrical section 28.

The spring Sii serves to impose a substantially proper tension on the cone 2U of the lock pin E when the handle is rotated to allow the locking portion of the pin to extend beyond the blade holding member and contact the blade. The spring 30 is suitably connected to the lower end of the section 26 and the upper end of section 28.

The spring 30 also serves to provide the proper tension on the blade when the blade is positioned in the blade holding member.

It will be noted that when the handle is turned in a counterclockwise direction or to the lefthand side as Fig. 1 is viewed with relation to the blade holding member that the locking portion of the lock pin is withdrawn into the inside of the cylindrical portion C of the blade holding member B. This allows the blade to be taken out of the holder.

When the blade is being inserted, the blade isV placed in the holder, and the handle is turned in a clockwise direction in relation to the blade holding member. This draws the cylindrical portion of the blade holding member into the handle and allows the locking portion of the lock pin to project to a position where it engages the blade. In this position slight pressure is exerted on the spring 33. This insures proper tension on the blade without putting excessive tension on the same.

The lower end 28 of the locking mechanism is securely fastened into a plug 29. The plug 29 is in turn securely fastened to the casing of the handle. By this arrangement when the handle is rotated in relation to the blade holding member, the locking pin is also rotated with the result that the mechanical movements above described take place.

In Fig. 4 I have shown a modification of the.

blade portion of the safety razor wherein an assembled blade comprised of two parts is posi- Vtioned in the holding member. A V-shaped member S is out in the back edge of the blade, and at this point the locking pin engages the blade. Otherwise, the device is substantially as shown in Figs. l, 2 and 3.

Fig. 5 is a side elevational view of the blade shown in Fig. 4.

Fig. 6 is a further modification of my device wherein the blade is on ya slant in Vrelation to the serrations on the edge of the blade holding member. This provides for a clear cutting edge when the blade is moved over .the face.

The spring 25 is positioned within the hollow handle and surrounding the lower portion 28 of the locking mechanism. This spring is arranged to exert pressure between the plug and is in the bottom o1" the holder and the lower edge of the cylindrical portion of the blade holding member B. This spring is provided to force the blade holding member upwardly in the handle so that the locking pin will be withdrawn in relation to the blade holding member and the blade released as shown in Fig. 2.

Although my invention has been described in considerable detail, such description is intended as illustrative rather than limiting, since the invention may be variously embodied, and the scope of the invention is to be determined as claimed.

I claim as my invention:
