SAFETY-RAZOR.

To all whom it may concern:

Be it known that I, ALoNzo NEWTON BENN, a citizen of the United States, residing at Chicago, inthe county of Cook and the State of Illinois, have invented a new and, useful Improvement in Safety-Razors,

I of which the following is a specification.

The object of my invention is to make the most convenient and efficient safety razor possible, having the detailed merits as herein set forth and theinvention is described in the claims.

Reference will be had to the accompanying drawings in which:

Figure 1 is a front elevation of the razor assembled for use.

. Fig. 2 is a view at right angles to that of Fig. 11

Fig. 3 is a similar view to that of Fig. 2

when the razor blades is adjusted at an incline. I I

Fig. 4 is a View on an enlarged scale of a part. of the handle looking in the same direction as that of Fig. 1. V

Fig. 5 is a central sectional view on an enlarged scale looking in the direction of Fig. 2.

F Fig. 6 is a sectional view on line 6-6 of Fig. 7 is a plan of the razor blade.

Fig. 8 is an elevation of the blade holder.

Fig. 9 is a plan sectional detail of the left side of Fig. 8 on line 99 of Fig. 8.

Fig. 10 is a plan of the guard piece.

Fig. 11 is a central section'on line 1111 of Fig. 10.

Fig. 12 is a sectional view showing the parts in a position when they are being put together or taken apart.

Fig. 13 shows the razor in position of shaving a concave region on the face.

In the drawing 1 indicates a milled handle in a form that is common with safety razors. 2 indicates a threaded stud which is screwed through a threaded hole in a cross-head 3 in a manner to turn freely in the cross-head and then is screwed tightly into a threaded hole in the end of the handle 1, the end 4 of the screw bottoming tightly in the end of the hole in the handle in a manner to hold the screw in place without movement in the handle in the ordinary use of the razor. The screw is provided with a conical pointed head 5 which furnishes an abutment end used in looking the parts together.

Patented July 1, 1919.

Application filed July s, 1916. Serial No. 107,320.

The ends of the cross-head 3 are provided 7 with holes 20 extending inward endwise about half way to the center of the crosshead, making as it were tubular ends for the cross-head. Into the sidesof the tubular ends are cut slots 21 which are enlarged on the handle side as is indicated by the openings 19. v

6 indicates the blade holder and 7 the blade and 8 the guard piece. The blade holder 6 is provided with posts 9 having I necks 10 and s herical heads 11. The posts 9 are chamfere off at 12 on the inside faces and at 13 on the sides to assist in assembling the razor blade.

The blade 7 is provided with holes 14 having rounded ends and straight sides as shown. The straight sides register with the flat spots 13 of the blade holder. The blade is provided with projections 15 to facilitate handling of the blade in assembling the same.

The guard 8 is curved in outline to fit the blade holder 6 and is provided with the ordinary guard fingers 16 common With safety razors and is perforated with the holes 17 to fit the posts 9 of the blade holder. A curved faced projection 18 is located on the inside istering over the posts 9 as shown by the dotted lines in Fig. 8, then the guard piece 8 is placed in contact with the blade and with its holes 17 registering with the posts 9. The parts are then pressed together flexing the b ade to the curved form of the blade holder the inclines 12 assisting, as has been said, in guiding and holding the blade as it is pressed toward the holder and passes over the chamfered parts of the studs between which it fits when fully home. The projection 15 facilitates handling the blade, it being possible, obviously, to compress the blade endwise as soon as flexing begins by more pressure of the fingers. Then the handle 1 with its cross-head 3 is placed in position the parts as is indicated by Fig. 12. The

handle is then rocked, bringing the slots 21 of the cross-head over the necks 10 ofthe posts 9 thus engaging the heads 11 within the tubular ends of the cross-head. Therepiece, the axis of this adjustment being the centerof the spherically shaped heads 11 of the posts 9. i

The holes 17 in the guard piece 8 are a little nearer the guards on one side than they are on the other side, that is the distance A -is a little shorter than the distance B, Fig.

10, for the purpose of causing the guard fingers 16 to project over the razor blade a v little farther on one side than on the other.

'lhispermits a littlemore clearance and a deeper cut'of the blade on one side than on i the other, pe'finitting the user to choose what '25 I desires.

suits him best for the class of .shaving he i The curved out-line of the razor is esecially serviceable in shaving concave suraces on the face as is indicated by Fig. 13,

'wherein the dotted lines indicate the out-line of the chin and 22 indicates the razor in position in sha'the concave space below the lower lip.

Heretofore .with safety razors having double edged blades held in place by means of perforations through the blade, it has been necessary to disconnect a greater number of pieces with more trouble and inconvenience 1n changing blades than with my device.

In the use of my razor I have simply to twist the handle slightly, loosening the screw head 5 just enough to free it from pressure against 'the projection 18 of the guard piece 45.

8 and then rock the handle and cross-head 3 until the openlngs 19 register with the heads 11 ofthe posts 9 whereupon the crossfhead 3: becomes disconnected-and the parts may then be separated. This .QPeration is much easier and simpler than are the con 'nections ordinarily found in razors of this class.

Besides the facility which my construction permits of in' replacing the blades, at the same t1me without extra'means or mech-.

anism, itprovides for the adjustment of the handle atdifi'erent inclined positions in relation to theblade, which is a very desirable convenience for users of razors of this class.

60 g I class are serious and although a. razor may .The fsanitary features of razors of this be "so shaped and constructed shave conveniently, if it-has'nothes, corners and inaccessableplaces which are not easily cleaned,' jit is an undesirable instrument. My
