UNITED STATES RAZOR BLADE SHARPENER Clifford E. McSwain and Cordell Smith, Bonita Springs, Fla.

Application June 20, 1933, Serial No. 676,730

3 Claims.

The invention relates to a hand sharpening implement and more especially a razor blade sharpener.

The primary object of the invention is the provision of a sharpener of this character, wherein a knife edge blade can be sharpened in a convenient manner, the sharpener being hand manipulated and capable of adjustment to vary the sharpening action thereof when in use.

Another object of the invention is the provision of a sharpener of this character, wherein safety razor blades can be easily sharpened with dispatch, these either of the double or single cutting edge type, the sharpener being of novel form and readily and easily handled when in use and assuring sharpening of the blade.

A further object of the invention is the provision of a sharpener of this character which is extremely simple in construction, thoroughly reliable and efiicient in its purpose, convenient for handling, susceptible of accommodating cutting blades of the safety razor type, and inexpensive to manufacture.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described in detail, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention, and pointed out in the claims hereunto appended.

In the accompanying drawing:

Figure 1 is an elevation of the sharpener constructed in accordance with the invention, showing by dotted lines the hands of a user and by full lines a safety razor blade in position for the sharpening thereof. 1

Figure 2 is a top plan view.

Figure 3 is a view similar to Figure 1 showing the sharpener in open position.

Figure 4 is an inner face view of one cheek part of the sharpener.

Figure 5 is a perspective view of the spring for the sharpener.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, the sharpener comprises a pair of cheek members or plates 10, these being alike and preferably of substantially rectangular form. Each member or plate 10 is formed with an extension or arm 11 at the heel edge and medially thereof. The arm at its free end is formed with a notch 12 constituting a seat for a purpose presently described.

Straddling the arms 11 of both members or plates 10 at the free ends of said arms is a substantially U-shaped leaf spring 13 which has its limbs 14 riveted or otherwise secured at 15 to the arms 11, while the bow or bight portion 16 of this spring is reduced in width and occupies the seats 12 in the free ends of the arms 11 so as to avoid lateral swinging movement of such spring or disalignment of the arms 11 with relation to the spring in the assembled condition of the sharpener.

The cheek members or plates 10 at their inner opposite faces carry leather pieces or slabs 17 for action upon the cutting edge of a safety razor blade 18 or other cutting blade for the purpose of the sharpening of the same or the reconditioning thereof.

In the use of the sharpener the same is placed preferably in the left hand of a user as illustrated at A, while held in the right hand as illustrated at B in the drawing is the blade 18 to be sharpened. The latter is placed between the pieces or slabs 17 as clearly shown in Figure 1 of said drawing. The thumb and index finger of the hand A exert a pressure on the cheek members or plates 10 against the opening action of the spring B and thus in this manner proper contact under pressure may be had upon the cutting edge of the blade 18 for the sharpening or reconditioning thereof. By sliding the blade 18 between the pieces or slabs 17 of the sharpener, sharpening action will take place for the sharpening of the cutting edge of said blade.

What is claimed is:

1. A sharpener of the character described comprising a pair of cheeks having leather pieces at their inner opposite faces, arms extending from said cheeks, and a spring straddling the arms crosswise of their free ends and made fast to said arms, the free ends of the arms being notched to provide seats for the spring.

2. A sharpener of the character described comprising a pair of cheeks having leather pieces at their inner opposite faces, arms extending from said cheeks, a spring straddling the arms crosswise of their free ends and made fast to said arms, the free ends of the arms being notched to provide seats for the spring, and fasteners securing the ends of the spring to the arms.

3. A sharpener of the character described comprising a pair of cheeks having leather pieces at their inner opposite faces, arms extending from said cheeks, a spring straddling the arms crosswise of their free ends and made fast to said arms, the free ends of the arms being notched to provide seats for the spring, and fasteners securing the ends of the spring to the arms, the straddling portion of the spring relative to the free ends of the arms being reduced for reception in the seats.
