7 RAZOR BLADE SHARPENER Filed Feb. l6, 1931 m g ATTORNEYS Patented Sept. 27, 1932 UNITED STATES- EDWARD C. BRYANT, F ATLANTA, GEORGIA RAZOR BLADE SHARPENEE Application filed February 16, 1931. Serial No. 516,169.

microscopic teeth along the cutting edge of the blade may be relined to restore said edge together with hand gripping and support engaging means so that the device may be either held in the hand while in use or securely attached to a support.

Another object of the invention is the provision of a blade sharpener which is simple as and economical in construction, and reliable and efficient in use.

With the above and other objects in view, the invention further includes the following novel features and details .of construction, to

be hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claim.

In the drawing I Figure 1 is a perspective-view of a razor blade. sharpener constructed in accordance with the invention.

Figure 2 is a transverse sectional view of the same.

Referring to the drawing. in detail where- 80 in like characters of reference denote corresponding parts, the reference character 10 indicates the body of the device which is arcuate in cross section and provides an upper convex sharpening surface 11. The body is made of glass or some other non-abrasive material and hasintegrally formed therewith spaced outwardly curved, longitudinally extending'fianges 12. These flanges are concaved along their outer surfaces as indlcated at 13 and provide finger gripping flanges whereby the device may be conveniently held in the hand for use.

The flanges 13 are spaced apart to provide .a slot or channel 14, the inner portions of the o posed side walls of which are parallel as in icated at 15. These parallel portions provide gripping means for engagementover the edge of a drawer or like member as ndicated in dotted lines at 16 in Figure 2. The L3 remaining portions of these walls are outwardly curved as shown at 17 so as to provide guides when attaching thedevice to the drawer or other supporting member 16-.

In use, the sharpener may be either held in the hand of theuser, or it may be attached as shown in Figure 2, while if desired, the sharpener may rest upon a broad flat surface, the flanges 12 having their lower edges disposed in the same plane.

By placinga blade upon the concaved surface 11 and exerting a slight pressure thereon while reciprocating the blade in the direction of the curve, the microscopic teeth along the edges of "the' blade will be forced inward. The blade is then reversed and the action repeated, at the'expiration of which all of the microscopic teeth which have become disaligned through the use of the blade, will be realigned so that the cutting surface will be restored.

j The invention is susceptible of various changes in its form, proportions and minor details of construction and .the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

Having described the invention what is claimed is v In a razor blade sharpener, including a bodyhaving an outer honing surface, .a pair "of spaced reversely curved finger gripping flanges extending from the body having straight alining ends to afford a support for the body when arranged on" the smooth surface, said flanges defining a sl t therebetween and.the opposed parallel wa Is at the inner end of the slot to define a gripping portion, and outwardly curved guide walls at the outer portion of the slot, for guiding a vertical support between said flanges and into gripping engagement with the parallel inner walls thereof.

In testimony whereof I aflix my signature. EDWARD O. BRYANT,
