SAFETY-RAZOR.

Specification of Letters Patent. Patented Dec. 2'7, 1910.

Application filed September 18, 1909. Serial No. 518,424.

To all whom it 'may concern:

Be it known that I, ALFRED MORGAN Pom- DEXTER, a citizen-of the United States of America, residing at Red Bank, in the State of New Jersey, have inventeda new and useful Improvement in Safety-Razor's, of which the following is-a specification.

-My invention relates to improvements in razors and more particularly to that class of razors known. as safety razors, and the object of my invention is to provide a razor which, while possessing all the advantages yet overcomes the declass of razor-now in use. I

It is obvious'that the easiest and most comfortable method 'of shaving; is that in Which the least possible resistance is encountered to .the cutting of the hair." This, as is well.

known, can be accomplished only by the proper position of the razor in shaving, in which the lateral surface of the bladeis held against the face, and the edge of the blade adjusted diagonally to the line of the stroke; and it is to the ease and facility with which the old style or long blade razor lends itself to this position, that it owes its present superiority over the safety. Various attempts to adapt this feature to the safety razor have heretofore been unsuccessful, for the reason that the present type of construe,- tion employed in safety razors renders such a position ofthe razor in shaving extremely difficult' and awkward. The objection was sought to be overcome by surrounding the blade of the old style razor with a frame or guard, but this in practice was found to be not only awkward and unwieldy, but the delicate the old style razor, was thereby utterly destroyed.

In my invention hereinafter described, I have succeeded in devising a razor, which, while retaining all theadvantages of the safety is so constructed, that not only is the proper position ofthe blade in shaving always assured, but at the same time, the sliding diagonal stroke, conceded to, be the correct stroke in shaving, is without any ractice or skill on the part of the operator, imparted to the blade. This I accomplish in and shown in the accompanying drawings, in which Flgure 1 is a top view of mydevice, Fig. 2

poise and adjustment of the blade so essential to the successful manipulation of is a side View of the same, Fig. 3 is a view of the cutting member, Fig. 4 is a view of the retaining member, Fig. 5 is a view of the bolt used forsecuring the parts, Fig. 6 is a perspective view of the guard'and handle Fig. 7 is a View of my preferredform of handle; 1

Similar characters refer to similar parts throughout the several views.

My device comprises a guard member 1 on the, marginal sections or guard sections of which I These teeth are preferably graduated in length. The base 12 of the teeth 1 and the base 12 of the teeth 1 are preferably set in a line obliquely to the longitudinalline of the guard member, and the outer extremities 13 of the teeth 1 and the outer extremities 13' of the teeth 1" are preferably set in a line parallel with the longitudinal line of the guard member. A cutting member or blade 2 is provided to rest upon the guard member 1, and a retaining provide'a series of teeth 1 1'.

member 3, narrower than the blade member 2, is placed upon the blade member 2 and held in position by means of studs 4 4 on the retaining member 3, and intended to fit in the apertures 8 8 in the cutting member 2', and in similar apertures l0 10 in the guard member 1. These studs in the apertures in the guard member 1 and cutting member 2 are preferably so placed, as to give the blade member 2 a diagonal position on the guard member '1, so that the cut-ting edge of the blade member 2 will be nearer the edge of the teeth 1" 1 of the guard member 1 at one end than at the other. I also provide a post 7, upon the guard member 3 to pass through a central aperture 9, in the .cutting member 2, and

a similar central aperture in the guard member 1, upon which post the hollow handle 5 is placed. In the end of the hollow handle 5, I provide a bolt 6, internally screw threaded at its end section 12 to receive the externally screw threaded section uponthe end of the post 7.

I prefer to use the form of handle. shown in Fig. 7, substantially square in cross section, as by the use of this form of handle the desired position of the blade in shaving is always maintained; but any handle having two sides thereof parallel may be used to advantage. i

In the drawings I have shown, my device 110 in the sim lest form; but I do not mean to limit mys'e f to the form shown, as device may be adapted to any form" of razor in which guards are used, the essential feature being'the blade set diagonally across the same. So-too, I do not mean to limit myself to a ard provided with teeth, as the same result maybe obtained by the use of anyequivalent for teeth.

1 Having thus described my invention, what Iclaimis; In a.

a guard member provi ed with marginal teeth, graduated in -len h, a cuttm mendber set thereon substantially diagona ly-to a line drawn through the outer extremities of said teeth, and a retaining member, substantially as shown and described.

' 2.- In a device ofthe. character described, a guard section provided with marginal teeth, a cutting member set thereon substantially diagonally to a line drawn through 4. In a device of the character described,

device of the character described,

a guard member, having its guard section provided with teeth graduated in length, a cutting member set thereonsubstantially diagonally to the exterior line of said guard member, substantially as shown and described.

5. In a device of the character described,

the combination of a guard member-prd. vided with marginal teeth graduated in length, a cutting member set substantially diagonally thereon and parallel to the base of said marginal teeth, a, retaining member,

and a handle, substantially as shown and described.

6. In a device of the character described, the combination of a cutting member and a guard member provided with marginal teeth graduated in length, whereby'in operation the cutting edge is. presented obliquely to the line of stroke, substantially as shown.- and described.

7. In a device ofthe character described, the combination of a cutting member and a guard member provided wit marginal teeth graduated in length, the base line of which teeth is parallel to the edge of the cutting member,-substantially-as shown and described.
