GEORGE L. SULLIVAN, OF KANSAS CITY, MISSOURI.

KNlFE-SHARPENER.

SPECIFICATION forming part of Letters Patent No. 772,542, dated October 18, 1904.

, Application filed March 4, 1904. Serial No. 196,592. (No model.)

citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have. invented certain new and useful Improvements in Knife-Sharpeners, of which the following is a specification.

My invention relates to knifesharpeners, and more especially to a sharpener for meat and bread knives; andmy object is to produce a device of this character by which knives can be sharpened quickly and easily, which is adjustable to accommodate knives of different bevels, and which is of simple, strong, durable, and cheap construction.

To these ends the invention consists in certain novel and peculiar features of construction and organization, as hereinafter described and claimed, and in order that it may be fully understood reference is to be had to the ac hardened properly-tempered steel, pivotally mounted on bolt 3 and formed below the latter with oppositely-bowed portions 8 and 7 respectively, the lower ends of said bowed'portions being connected by a retractile spring 9, which tends to hold the blades 5, and 6 in substantially the position shown in Fig. l, and in this 2 connection it will be noticed that the inner or opposing edges 10 of the blades converge, as shown clearly the arrangement being such that when a knife .is introduced between the blades, as shown in dotted lines, Fig. l, and

is drawn toward the operator it will be quickly and efliciently sharpened.

If desired, the clamping-nut may be screwed upon the bolt '3 only a sufficient distance to hold the blades together, so as to permit the spring 9 to hold the cutting'edges of said blades together with a yielding pressure; If preferred, however, the wing-nut can be screwed home upon the bolt so as to clamp the blades in'rigid relation to each other, at which time of I course the spring is functionless. By clamping said blades at different angles it is obvious that it'is possible to give the knifeblade dilferent bevels or to accommodate the diiferent bevels of the knife-blades.

The manner of placing the sharpener in position will be readily understood by reference to Fig. 1, as the spring-clamp portion 2 is simply forced upon the edge of the table, from which position it can be readily removed; From the above description it will be apparent that I have produced a knife-sharpener embodying the feature of advantages enu-.

merated as desirable in the-statement of invention, and while I have illustrated and described its preferred construction it is obvious that it may be modified in some particulars without departing from the principle of construction involved.

Having thus described the invention, what 2 the presence of two witnesses.
