2,610,396 Straight Safety Razor Frank Sherosky, Detroit, Mich. Application June 21, 1950. Serial No. 169,379. 1 Claim. (Cl. 30—69)

My Invention pertains to a safety razor in which the blade is of the type known as a straight razor, the blade including a thick heel or back portion and tapering therefrom towards the cutting edge, the faces of the blade between the heel and the cutting edge being of hollow ground contour. The blade is associated with a safety guard which will be presently described. The object of my invention is to provide a razor in which the blade is associated with a guard and a handle, the blade with the guard being adapted to be mounted either endwise or crosswise upon said handle, as desired. A further object of my invention is to provide a razor including a blade to be used in the manner of a straight razor but with a guard thereon, which guard may be frictionally held upon the blade without any special additional means.

Another object of my invention is to provide a razor in which the relative position of the cutting edge of the blade with respect to a part of the guard extending along said cutting edge may be conveniently regulated by a turn of the handle. A further object of my invention is to provide a razor blade which, when mounted on the handle endwise, may be honed or stropped in the manner of a straight razor.

I shall now describe my invention with reference to the accompanying drawings, in which:

Fig. 1 is a perspective view of my razor as assembled for use;

Fig. 2 is a side elevational view of said razor;

Fig. 3 is a side elevational view of the handle of my razor;

Fig. 4 is an enlarged sectional view on line 4—4 of Fig. 1;

Fig. 5 is a perspective view of the blade comprising one element of my razor;

Fig. 6 is a perspective view of a guard adapted to fit over the blade;

Fig. 7 is a perspective view of a handle and a blade mounted thereon endwise in the manner of a straight razor;

Fig. 8 is a perspective view of the blade with a guard thereon, and a fragment of a handle, the blade being set endwise upon said handle.

Similar numerals refer to similar parts throughout the several views.

The razor comprises three separate elements: the blade, best shown in Fig. 5; the guard, best shown in Fig. 6; the handle, best shown in Fig. 3.

The blade, generally indicated by numeral 10, includes a thick back portion or heel 11 defined by a flat rear surface 12, a flat upper surface 13, and a parallel flat under surface 14. The body of the blade tapers from the heel to the cutting edge 15, the faces 16 of the blade, between the heel and the cutting edge, being hollow ground, as best shown in Fig. 4. The blade is provided with two threaded openings of the same diameter, one, indicated by numeral 17, being located within the heel of the blade at one end thereof, as best shown in Fig. 5. The other opening 18 is located midway the length of the blade in the heel portion thereof and extends crosswise thereto and at an angle to the medium plane of the blade, as best shown in Fig. 4.

The guard, generally indicated by numeral 19, includes a rectangular channel-like portion20 adapted to fit snugly over the heel portion 11 of the blade, and an apron 21 extending forwardly towards edge 15 of said blade. The marginal portion of the apron includes a lip 22 extending forwardly of the edge and slightly curling outwardly. The apron part of the guard is provided with an opening 23, the opening being located so as to be alined with the threaded opening 18 with in the blade.

The handle 24, made of cylindrical stock, includes a threaded end 25 of a diameter to pass through opening 23 in the guard and to fit into either of the threaded openings of the blade, that is, into opening 17 or 18. A portion 26, being of a reduced diameter, separates the threaded end 25 from a shoulder 27.

When the razor is to be used in the manner of a conventional straight razor, the threaded end 25 of the handle is screwed into the end opening 17 of the blade, as shown in Fig. 7, whereupon the guard 19 may be slipped over the blade endwise. The razor, thus assembled, is shown in Fig. 8.

When the blade is to be disposed transversely to the handle, the guard is first slipped over the blade in such a manner that the opening 23 in the guard is alined with opening 18 in the blade, whereupon the threaded end 25 of the handle may be inserted through the opening in the guard into the threaded opening 18 and screwed in place. It will be noted that the shoulder 27 of said handle will fit under the apron 21 of the guard, as shown in Fig. 4. It will be further noted that normally there is a slight spacing between the faces of the blade and the surface of the apron adjoining it, as shown at 28. As the handle is turned into the blade opening 18 or out of it, the spacing may be decreased or increased, this serving to adjust the spacing between the lip 22 of the guard and the edge of the blade. This is an important feature of my invention which up to now has not been shown in razors of this type.

For stropping the razor the blade is simply affixed endwise to the handle, as shown in Fig. 7.

It will be understood that some changes may be made in the structure of my razor without departing from the inventive principle disclosed herein.

What I, therefore, wish to claim is as follows:

A safety razor comprising a blade having a thick heel portion defined by a flat back, a flat top, and a flat under side, said blade tapering from the heel portion to a cutting edge, the blade being provided, midway its length and transversely thereto, with a threaded opening, a guard frictionally retained over the heel portion and including an apron on the under side of the blade, the apron extending in the direction of the edge of the blade and being in a yieldable progressively expanding spacing to said blade, the guard being provided with an opening for alinement with the threaded opening in the blade and including an outwardly extending lip along the edge of the blade and in a normally spaced relation thereto, and a handle having a threaded end for engagement with the threaded opening in the blade and a shoulder below its threaded end for abutment with the apron at a point where the apron is spaced from the blade to adjust the spacing between the lip of the apron and the cutting edge of the blade.
