(No model.)

To all whom it mag/concern:

Be it known that I, KING CAMP GIILETTE, a citizen of the United States, and a resident of London, England, have invented new'and use--v -spect to which itis positioned bymeans 'of pins or the like passing through'the perforations in the blade, such a razor being described and claimed in my application for United States LettersPatent, Serial No. 84,552, filed December 3, 1901, of which application this present application is a division.

The razor specifically shown and described in my said prior application has a thin ilexible blade provided with two opposite cutting edges, and the two sides of the4 holder are made alike, the handle being symmetrically disposed midwaybetween them, so that either edge of the blade can be used without altering its position in the holderzand my present improvements are hereinshown and described as embodied in a' razor hav'igv the same general characteristics-that is to say; a doubleedged .flexible blade, a double guard, and a symmetrically-disposed handle; but it is to be iinderstood that this particular construction and arrangement of these parts isnot essential to the main features of my present invention.

Figure 1 is an end elevation, partly in section, of the complete razor, showing the parts in position ready for use. Fig. 2 is a central longitudinal section through the same. Fig. 3 is a view similar to Fig. l, but .showing the parts of the razor partly separated. Fig. 4 is a plan view of the outer face of the head of the razor, and Fig. 5 is a plan view of the razor-blade.

Referring to the drawings, 2 indicates the blade of the razor, which is usually made of sheet -steel having a uniform thickness of about six one-thousandths of an inch and'provided with two opposite cutting edges 3. The

holder comprises a backing 4, a guard-piece 5. a handle 6, carried by the guard, and means for moving the guard and backing toward or from each other. backing 4 is of the same length as but slightly narrower than the blade 2, being thus adapted to support the blade near its cutting edges and impart the necessary rigidity thereto when-the blade is secured in place. The longitudinal edges of the guard 5 are of the same gether 1 provide a pin or bolt 9, carried by the backing and having its free end threaded to engage the internally-threaded hollow end of the handle 6, whichV is preferably located vwithin a sleeve or socket l0, secured to or formed integral with the guard. and is held to turn' in said -sleeve by means of a pin 11, passing through the wall of the sleeve and entering an annular groove 12, cut in the handle.

When the parts are assembled, the blade 2 is located between the guard and the backing, and in order to position the blade the backing is provided with pins or lugs 13, adapted to pass snugly through openings or perforations 14, formed at the proper points in the blade. The guard is preferably positioned by means of the same pins, which are made long enough to pass through perforations 15, formed in the guard, and registering with the perforations 14 in the blade when' the parts are in proper relation. l

When the blade and guard are double-edged, as shown, the sleeve 10 is located at the center of the guard and extends at right angles thereto, and the blade is centrally perforated, as at 16, to receive the bolt 9; the pins 13 and the registering perforations 14 and 15 in the blade and guard being also located midway In the present instance the between the edges of the holder and at equal dmetrical arrangement of the handle permits either edge of the razor to be used with equal facility. V

In the construction illustrated the adjacent surfaces of the guard and backing conform in area and contour, or substantially so, thus providing rigid supporting-surfaces for the blade throughout practically the entire area I ofthe latter when clamped between said parts,

and in order to utilize the tlexibility andelasticity of the thin blade for the purpose of obtaining an adjustment of its cutting edges toward and from the edges of the guard these conforming-surfaces ofthe guard and backing are somewhat curved transversely, so that the blade is bent transversely and its cutting edges are caused to approach closer and closer to` the notched edges of the guard as the guard and backing are drawn together or permitted to' spring away from said notched edges as the guard and backing are separated. In Fig. 4 the backing 4 is shown as provided at each corner with a lateral projection 17, adapted to extend slightly beyond the edge of the corresponding corner of the blade and lie close against the same, thus covering the rear side thereof. This feature, as well as an arrangement similar to that above described for ad.-- justing the cutting edges of the blade, is described and claimed in my prior application,

Y Serial No. 84,552, above referred to, and isincluded herein in order'to illustratethe pref It is one of the -features of my present im' provements that after the guard and handle have been detached from the backing the blade may. still be held in place on the'back- `ing by 'means of the positioning-pins and may b'e grasped by its ends andreadily applied or removed without having to be slid laterally.

as has been the practice heretofore. I claim as myinvention- 1.` In a razor, the combination with forated blade, of a holder comprisinga han# between` the sides of a supporting-framework,

die, a backing provided with positioning-pins l a per# arranged to pass through the perforations in the blade, a guard, and means for clamping said blade between the backing and the guard.

2, In a razor, the combination with a perforated flexible blade, of a holder comprising a handle, a rigid backing .forming a support for said blade and provided with positioningpins arranged to pass through the perforations therein, a guard, and means for clamping said blade between the backing and the guard.

3i In a razor, the combination with a pertral screw-threaded bolt, a guard curved transversely to correspond with said backing and aving its opposite longitudinal edges notched, a flexible blade having two opposite .cutting edges and provided with perforations arranged to'receive the bolt and positioningpins, and a handle having its inner end internally screw-threaded to receive said bolt.

5. Ina razor, the combination with a perforated blade of a holder comprisingaguard, a handle, a backing, and clamping means passing through the blade, said blade and backing being so formed that the ends of the former project beyond the ends 0T the latter.

6.' In "a razor, the combination with a perforated blade .having two opposite cutting edges, of a holder comprising adouble guard having perforations corresponding to those in the `blade, a backing provided with posi- IOO tioning-pins passingthrough the blade and guard, a handle, and means for detachably clamping the blade between said backing and guard.

7. In a razor-,Va holder comprising a backing provided with positioning-pins and with a central screwthreaded bolt, a double guard provided with"perforatious adapted to receive said positioning-pins and bolt, and a handle provided with an internally-screw-threaded nut adapted to receive said bolt.

8u. In'a razor, a holder comprising a trans- `versely-curved, rigid backing provided with positioning-.pins and with a screw-threaded bolt, a -guard curved transversely to correspond with said backing and perforated to re ceive said positioning-pins and-bolt, and a handle provided with an internally--screwthreaded nut adapted to receive said bolt.

9. A safety-razoromprising a back plate,

IIO

a clamping-plate, a. handle piojecting from 'means for securing the plate, bladeaud guard said plates at substantially a right angle, a together. v

sleeve connected to said clamping-plate and mounted on the handle, and mea-ns for adjusting said plates toward and from each other.

l 10. A safety-razor comprising a back plate having lugs, a blade, a guard, both the blade and guard having openings for said lugs, and

1n testimony whereof I have hereunto subscribed my name this 10th day of May, 1904.
