T 0 allwhom it may concem: I

Be it known that IQWA TER ALTHOFF, of Genevafiin, the county of @ntario, in the Stateof New 'Yorlghave invented new and useful Improvements in Adapters for Safety Razors, of'wh-ich the following, taken in con nection'with the accompanying drawings, is a full, clear and exact description.

This invention relates to an adapter for safety razors.

The object of the invention is to produce a device capable of being assembled with the ordinarysafety razor of the double edge blade; type to adapt said razor for use "with a single-fedge-blade.

Furthen'safety razors of the double edge blade type support the blade in a position practically at right angles to the longitudinal axis or extension of the handle so that the handle must be held at substantially right position is unnatural, and somewhat difficult/for the hand of the operator to assume, and another object of the invention is to produce a simple and inexpensive device, capa- Jole of assemblage with a razor'of the doubleedge blade type that will support a blade in a normally inclined position disposed at a substantial angle to the plane perpendicular to the longitudinal axis of the handle. Thus,

a razor substantially of'the character known as hoe type is produced.

Other objects and advantages relate to the details of construction form and arrange ment of the adapter, all as will more fully appear from the following description,

" taken in connection withthe accompanying drawings, in which Figure 1 is a perspective view of a razor having my adapter applied thereto.

Figure 2 is a perspective view of the adapter.

Figure 3- is a perspective .view of a blade.

Figure 4 is a sectional view through the assembled structure of Figure 1.

The ordinary razor of the double edge blade type consists of a base late 1 having a series of openings therethrough, in this instance three and a top plate 2 having a series of lugs 3, 4 and 5- projecting therefrom and adapted to extend through the openings in the base plate -1-. The central projection -4 is preferably externally threaded for engagement with the internally threaded hollow end of the handle withia razor of this type, andfor thatfpur- 20 so that by screwing the handle upon the stud the base plate and top plate are drawn together to grip between them the "ordinary'idoubl ei edge razorblade, such blade belng usually provided withfaseries of openings equal in number to the studs upon the top plate for the reception and passage of said studs.

My adapter is designed for assemblage pose is provided with a concave base -7-.

having three .recesses,': 87--, .9'-. and 10 in thefront edge ofsaid base for the: 1

respectively. As shown, the base plate --'1 and the top plate -'2 are both of a somewhat 'concavoeco'nvex nature, and the conveXity of the base 7is1sonieWl-1at greater; than'that of thecap late 2 and the base;

plate '1 respectively,.so' that w-henfthe cap plate is drawn toward the base plate, the radius ofltheconcavity of the base -71 will be lengthened to a limit where its concavity is of a radius similar tov theconvexity:

of the base plate 1-, or the concavity of This operation-not only affords a tightyen- I gagement between the adapterja'nd the razor part, but effects a gripping of the razor, as hereinafter described. v The basey 7' is provided withla rear wall the adjacent surface of the cappl'a-te I ll 11"extending upwardly and forwardly wardly and downwardly inclined v flange 16 for engagement with the outer'js'urand is provided at its-lower end with a forface of the razor blade to hold thesame tightly" against the wall: of the receiving space 13 and against thefrontedge of the cap plate 2 andjthe upper surface of the base plate l'wliich is prov-idjed in the usual manner at its edgeswith teeth.-";'

The adapter may first be applied to; the

razor structure and the blade may be slid laterally into the groove or receiving space 13 and at the rear of the flange -16 and in front of the edge of the cap plate --1. By screwing handle 6 to draw the cap plate -2-- toward the base plate -1 the scraping of the convex base --7- of the adapter will throw the rear wall -11- downwardly, causing the flange -16- to force the blade 14: against the wall of the receiving space -13 and against the front edge of the cap plate 2, the rigidity and firmness of such engagement of the parts being determined by the extent to which the concavity of the base 7- is increased in radius to the point where it conforms with the convexity of the adjacent surface of the base plate -1-, or the concavity of the adjacent surface of the cap plate -2-.

Preferably, this adapter is formed of a single piece of sheet metal which has sufficient rigidity to effect the purposes at hand, and still has a certain amount of flexibility and resiliency which permits tight frictional engagement of the parts without absolute immovability. Thin sheet steel is found Suitable for the purpose at hand. However, itmay be that other suitable materials having the desired flexibility and resiliency may be substituted, or in certain cases perhaps with less preferable results rigid mate rial may be substituted, and I do not, therefore, desire to limit myself except as set forth in the claims hereto appended to any particular material or to any particular flexibility or to the exact form and shape of the adapter, as here shown, as various changes and modifications may be made in the materials from which the same is made, and in the form and shape of the adapter, without departing from the invention, as set forth in the appended claims.

I claim I 1. The combination with a base plate and a cap plate adapted to receive a razor blade between them, of means having a portion positioned between said base plate and said cap plate for holding a razor blade in an exterior position.

2. The combination with a razor part, including a base plate and a cap plate adapted to receive a razor blade between them, of a blade-holding member having a concave flexible base positioned between the cap plate and the base plate. I

3. The combination with a razor part, including. a base plate and a cap plate adapted to receive a razor blade between them,

of a blade-holding member having a concave flexible base positioned between the cap plate and the base plate, said concave flexible resilient base being of greater concavity than the adjacent surfaces of the cap plate.

4. The combination with a razor part, including a base plate and a cap plate adapted to receive a razor blade between them of a blade-holding member having a concave flexible base positioned between the cap plate and the base plate, the concavity of the base being shorter than the radius of the convexity of the adjacent surface of the base plate.

5. The. combination with a razor partincluding a base plate and a cap plate, of .a blade-holding member having its base POSI'. tioned between the base plate and the cap plate and provided with an upwardly inclined rear wall extending from the base, and a downwardly inclined front wall extending from the upper end of the rear wall.

6. The combination with a razor part including a base plate, and a cap plate, of a blade-holding member having its base positioned between the base plate and the cap plate and provided with an upwardly inclined rear wall extending from the base, a downwardly inclined front wall extending from the upper end of the rear Wall, and a razor receiving groove separating the upwardly inclined rear wall and downwardly inclined front wall.

7 The combination with a razor part inplate and provided with an upwardly inclined rear wall extending from the base, and a downwardly inclined front wall extending from the upper end of the rear wall, said front wall provided at its lower end with a rearwardly directedflange for contact with the razor blade.

8. The combination with a razor part in cluding a base plate and a cap plate, of a blade-holding member having'its base positioned between the base plate and the cap plate and provided with an upwardly inclined rear wall extending from the base, and a downwardly inclined front wall extending from the upper end of the rear wall, and a razor receiving groove separating the upwardly inclined rear wall and downwardly inclined front wall, said front wall provided at its lower end with a rearwardly directed flange for contact with the razor blade.

In witness whereof I have hereunto set my hand this 3rd ,day of October 1921.

WALTER ALTHOFF.
