ISAAC ATWOOD ABBOT, OF DENVER, COLORADO.

SC ISSORS-SHARPENER.

PECIFICATION forming part of Letters Patent No. 372,886, dated November 8, 1887.

Application filed February 23, 1587. Serial No. 228,547. (No model.)

To all whom it ma'y concern:

Be it known that Llsnno ATWOOD ABBOT, of Denver, in the county of Arapahoe and State of Colorado, have invented anew and Improved Sorissors-Sharpener, of which the tfollowing is a full, clear, and exact descrip- My invention relates to a device specially intended for sharpening scissors, but adapted also for sharpening other bladed cutting-instruments; and the object of the invention is to provide a simple, inexpensive, and efficient sharpener of this character.

The invention consists in certain novel features of construction and combinations of parts of the scissors-sharpener, all as hereinafter fully described and claimed. I

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a front view of my improved scissors-sharpener and a part of a table or shelf to which it is attached, and shows in cross-section the blade of apair of scissors in position to be sharpened. Fig. 2 is an edge view of the sharpener, with the table and scissors-blade indicated in dotted lines. Fig. 3 isaside view of the body or stock of the sharpener with the attached'gage in section. Fig. 4 is a face view of the sharpening-disk, and Fig. .5 is a face view of the auxiliary sharpening-blade.

The body or stock A of the sharpener is formed with a bowed lower portion, a, to the extremity of which a screw, 13, is fitted, to allow the device to be clamped to a table or shelf, 0. The head of the stock A is formed as a flat plate .or flange, a, having a threaded hole, d, to receive a screw, D, by which the main sharpening-disk E and the auxiliary sharpening-blade F are held securely to the stock, all as clearly shown in Figs. 1 and 2 of the drawings. A gage, G, having an outwardly-projecting flange, g, is held to the top of the plate a of the stock A by screws H, which pass through slots in the gage, allowing it to be set to bring the flange g at the desired angle with the periphery of the disk E and the edge f of the blade F for sharpening the scis- 5o sors-blade I, as presently explained. The disk E is made sharp at its periphery by beveling it from either one or both faces, and the disk has a central hole, 6, snugly fitting the screw D, on which it may be turned to present an other cutting part of its periphery when dulled at any one place, and the diameter of the disk allows its cutting-edge or periphery to stand but a little above the base portion 9 of the gage G; hence said part of the gage serves as a. stop to prevent the disk E cutting too deeply or unevenly into the blade of the scissors. The auxiliary blade F is made with a slot, f, allowing it to be shifted on the fastening-screw D to present a new portion of its cutting-edge-f at the angle formed by the face of the gage-flange g and the periphery of the disk E when the edge f becomes dulledor worn by use.

I purpose making the sharpening-disk E,

blade F, and gage G of hardened or tempered steel, and the stock A, with its clamp-screw B, of cast-iron or brass or other suitable metal. I In using the sharpener the gage G will be set so that its flange 9 stands at the desired angle with the sharp periphery of the disk E, and the blade F then will be set with its edge f aboutflush with the outer face of the gageflange, andboth the disk and blade will then be clamped tightly by the screw D. The scis- Sorsblade I to be sharpened will then be laid with its inner face flat against the gage, and will be drawn across the disk E, which will sharpen the edge of the blade I, and the edge f of the sharpener-blade F will remove the wire edge produced by the disk E at the inner face of the scissorsblade; hence scissors may be sharpened Very quickly and smoothly with the device by any person of ordinary intelligence, and the sharpener may be made and sold at a trifling cost. The blade F need not have the precise form shown, the essential features of it being the edge f, and this edge, combined with the slot f, allowing the edge f to be shifted, for purposes above described.

This instrument is not restricted in use to sharpening scissors, but may be used to advantage in sharpening other bladed cutters, as will readily be understood.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, in a scissors-sharpener,

of a stock, A, a disk, E, having a sharp periphery and a central hole, 6, and an auxiliary blade, F, having an edge, f, and a slot, f, and said parts E F held adjustably to the stock by 5 a Screw, D, passed through the hole 6 and slot 10 against which the blade to be sharpened rests,

and said gage held to a curved end part of the stock by screws H, passed through slots of the gage and allowing adjustment of the flange g at various angles to the periphery of the disk 15 E, substantially as shown and described.

3. The combination, in a scissors-sharpener, of a stock, A, adisk, E, an auxiliary blade, F, adapted to eoact with the disk in sharpening a blade, and said parts held to the stock by a sharpened, substantially as shown and described.

4. The combination, in a seissorssharpener, of a clamp-stock, A B, a disk, E, having acentral hole, 6, and a sharp periphery. a blade, F, having an edge, f, and a slot, f, and both parts E F held to the stock bya screw, D,and a gage, G, having a flange, g, guiding the blade being sharpened, and a part, as a stop to said blade, and said gage held to the stock by screws H, passing through slots of the gage, substantially as described, for the purposes set forth.
