AVABY 1B. CARROLL, OFNOIRFOLK, VIRGINIA...

SAFETY-RAZOR.

Application fi1ed August 28, 1916. Serial No. 116,523.

Be it known that I, AVARY B. CARROLL, a citizen of the United States, and resident of Norfolk, in the county of Norfolk and State of Virginia, have invented certain new and useful Improvements in. Safety-Razors, of which the following is a specification.

The present invention relates to'the art of cutlery and has particular reference to new and useful improvements in safety razors.

The primary object of my invention is to provide a safety razor which is cheap to manufacture, easy and safe to use and effective in operation.

Another object of my invention isto provide a safety razor in which the cutting elements are so arranged that a draw out is provided tending to greatly enhance the eficiency of such razors and render the same more safe.

A further object of myinvention is to provide a safety razor having new and improved means for supporting a plurality of the blades for cooperation in shaving.

A still further object of my invention is to provide a safety razor of the class described having a frame for supporting a plurality of blades at proper angles whereby to afiord an efficient cutting action when presented to the face of the user. 7

Other objects and advantages to be de rived from the use of my improved safety razor will appear from the following detail description and the claims, taken with an inspection of the accompanying drawing, in which:

Figure 1 is a front elevational view of a safety razor embodying the improvements of my invention;

, Fig. 2 is a fragmental perspective view of the same;

Fig. 3-is a transverse sectional view taken on the line 3-3 .of Fig. 1;

Fig. 4 is an enlarge sectional view taken on the line 44 of Fig. 1;

Fig. 5 is an enlarged detailed sectional view of one of the blade retainers;

Fig. 6 is an elevational view of a blade holder for honing; and

Fig. 7 is a fragmental rear elevationalview of the blade supporting frame. Referring more-particularly to the drawings, wherein similar characters ofreference desi thro ii ghout the various views, I provide a frame having angularly related rectangular Specification of Letters Patent.

The inner A pair of arms 6 and 7 are connected fto the back faces of the wings 1 and formed of a single blank of magenta connected by a strip 3. The wings 1- and 2' 4 2, said. arms 6 and 7 being twisted together as at 8 to form a handle. I do not limit myself to this form of handle, the same merely being shown to indicate one type of handle which may be employed.

The blades are designated 9 and 10, the

same being provided with the usual bevelportions 11 and 12, respectively, to provide the cutting edges said blades being receivable on the wings 1 and 2,

I

The blades are clamped in position on their respective wings by means of holders 16 and 17. The

holders are identical in construction and I will is provided with a cylindrical outer surface and asquare opening indicated at 18, a pair 4,

formshank ofbolts 22, said bolts having fiat heads and n'al alinement with the inner end of the bevel 12 of the blade 10 so that in use the path of blade 10 overlaps the path movement of the of'movement of the blade 9 insuring complete removal of the hair and leaving no streaks. The blades are arranged slightly r the in spaced relation as at 24 to prevent spoiling the cutting edge of the blade 9.

A bolt 25 extends through the strip 3 and is provided with a fiat head 26, the inner surface of the head being beveled as at 27 to more readily grip the adjacent portions of the blades 9 and 10 and retain the same in position on the wings. A wing nut 28 is carried by the bolt 25. An enlargement 29 formed on said strip 3 serves to raise the blades 9 and 10 from the wings 1 and 2, similarly to the enlargement 15 hereinbefore referred to.

A rearwardly directed flange 30 is formed on the upper end marginal edges of the wings 1 and 2 and on the strip 3 to deflect the lather downwardly onto the rear surface of the wings and prevent the same from reaching a persons face while in course of shaving.

A holder for the blades 9 and 10 when being honed is shown in Fig. 6, the same including a handle 31 having a shank 32 provided with a squared portion 33 for insertion into the squared openings 18 of the holder 16. An annular collar 34 is formed on the squared portion 33, and a bolt 35 is provided in one end of said squared portion to clampingly engage the blades and firmly retain the same in position for honin It will be seen that in use when the lades are drawn down over the face of the user a slanting cut will be afi'orded instead of a straight out, thereby rendering more efficient the operation of the razor and preventing injury to the face of the user. Any part of face may be reached by my improved razor, the an lar relation of the blades as well as their arrangement in angularly related planes serving to provide a more eflicient cutting operation. The provision of .the holders 16 not only afiordmeans for holding the blades for honing but also serve as guides when using the razor, the same serving to dispose the blades at the proper angle to the face. The blades and wings are cut away as at 36 so that when starting to out along the side of a persons face the corners of the blades will not cut the users ear. I desire to lay particular stress upon the arrangement of the blades both with regard to their planes and longitudinal axes, this being the principal feature of my invention. It will be seen that the blades are supported at three points and are clamped at two points each so that accidental dislodgment of the blades when in use is practically impossible. It will be readily aptherefrom, said frame aaaaeai parent to those skilled in the art that in the provision of my improved safety razor I have afforded a device which is exceedingly simple in construction, efiicient in operation as Well as cheap to manufacture and sell.

From the above description taken in connection with the accompanying drawing, it is thought that a clear and comprehensive understanding of the construction, operation and advantages of my invention may-be had, and while I have shown and described the device as embodying a specific structure, I desire that it be understood that such changes may be made in said structure as do not depart from the spirit and scope of the invention as claimed.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a safety razor, the combination of a supporting frame including a pair of wings having their longitudinal axes relatively at right angles, a plurality of blades disposed on said wings, said blades having enlargements provided with elongated openings, and means passing through said wings and said enlargements to clampingly engage the blades and retain the same upon said wings.

2. In a safety razor, the combination of a supporting frame, handles extending being formed with win portions, said wings having their longitudinal axes relatively at right angles, a plurality of blades to be disposed on said wings, a bolt extending through said frame to engage the adjacent corners of said blades, said corners being in offset relation to permit the path of travel of one blade to overlap'that of the other, and a deflecting flange formed on said wings at the upper marginal edge thereof.

3. In a safety razor, the combination of supporting frames including a pair of wings having their longitudinal axis relatively at right angles, a strip connecting said wings adjacent their outer edges, a plurality of blades disposed on said wings, a holder for said blades, a pair of spaced tongues extending therefrom adapted to embrace the blades, means for securing the blades to said tongues, and a bolt member passing through said wings in said holder to clampingly engage the blades and retain the same upon said wings.

In testimony whereof, I affix my signature hereto.

AVARY B. CARROLL.
