Application filed July 19, 1918, serial No. 245,848.
To all who met may concern:
Be it known that I ALBERT MGGALL, a citizen of the United tates, and a resident of New York in the county of New York and State of lllew York,. have invented certain new and useful Improvements Safety-Razor-Blade Sharpeners, of which the following is a specification.
My invention relates to Sharpeners for knives or safety razor blades or other keenedged cutting instruments.
he object of my invention is the production of a sharpener of extreme simplicity of construction, of low cost to manufacture and which may be utilized to efi'ectively and expeditiously sharpen the cuttingedge of the blade it is desired to sharpen.
To the above ends my invention consists in the various parts and combinations of parts hereinafter more particularly described and then specified in the'claims.
In the accompanying drawing:
Figure l-is' airont elevation of my improved sharpener.
Fig. 2 is a side elevation of the same.
Fig. 3 is a horizontal section of a modification oi sharpener.
Referring more particularly to the several figures of the drawing:
1, 2 indicate the arms of my improved sharpener consisting prefera ly of two. fiat pieces of metal joined together at their lower ends by suitable rivets 3 or by other suitable means. The arms 1, 2 are provided adjacent their upper ends with circular openings 4. acting as seats for and adapted to receive the sharpening elements 5 which have curved meeting surfaces normally contacting with each other and which are held yieldingly together by the arms 1, 2 as illustrated. The sharpening elements 5 consist preferably of balls made of hard steel although the invention is not limited to any specific material of which the sharpening elements must be constructed nor is it limited to making them exactly spherical in shape as long as they have rounded meeting surfaces, (5 indicates the cutting edge of the razor blade 7 or other blade it is desired to sharpen. The cutting edge is sharpened in an obvious manner by merely drawing it between the sharpenin elements 5 in the position indicated in 11g. 1. As is obvious inasmuch as specification of Letters Patent.

the sharpening elements are at all times yi'eldingly held together to permit them to be moved away from each other during the sharpening operation and inasmuch as there is a constant take-up therebetween, no special adjustment of their position is at anytime necessary to accomplish the sharpening of the desired, blade.
In the modification illustrated in Fig. 3,
' 8 indicates the body of ahox having a cover 9 provided with a slot 10. The means for holding the sharpening elements 5 together in this case consists of a receptacle provided with a base 11 having vertical side arms 11 within which receptacle is provided elements 12 having circular openings adapted to receive the sharpening elements 5. The sharpening elements are yieldingly held togather by means of the springs 13 interposed between and bearing against the side arms 11 and the elements 12 and to which side arms and elements-they are preferably attached. To sharpen the blade, it is inserted in the slot 10 and the or. ting edge drawn between the sharpening elements 5 in the same manner as in the preferred form of my invention. 7
What I claim as my invention is 1. A blade sharpener comprising sharpening elements having op osed curved surfaces and spring means tor normally holding said sharpening elements in engagement with each other and adapted'to permit said sharpening elements to be forced away from each other during the sharpening operation.
2. 1%. blade sharpener comprising sharpen ing elementshaving opposed curved surfaces and means for normally holding said sharpening elements together with their curved surfaces in engagement with each other; said means being adapted to permit said sharpening elements to be forced away'from each other and adapted also to permit a constant take-up. between the sharpening elements during the sharpening operation.
3. A blade sharpener comprising spherical sharpening elementsnormally engaging each other and retaining means for said sharpening elements consisting of two strips of metal joined together and adapted to hold said sharpening elements yieldingly togather.
sharpening elements normally engaging each sharpening elements during the sharpening other and retaining means for sand sharpenoperation ing elements consisting of two strips of Si ed. at New York in the county of metal joined together at the lower ends and New orkand State of Iiew York, this 18th 5 provided with circular openings adjacent day of July A. D. 1918..
