KNIFE-SHARPENER.

Speccaton of Letters Patent.

Patented Dec. 7, 1909.

Application filed February 4, 1909. Serial No. 476,042.

To all whom it may concern:

Be it known that I, Moens L. HAwxs, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Knife-Sharpeners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to knife sharpening devices and particularly to that type which employ a cutting or shaving steel and a guiding portion or body.

The object of the present invention is to improve upon former patents taken out by me and to render the device more serviceable and at the same time cheap in its construction.

A still further object of the invention is the provision of means whereby the guiding means for the scissor blades may be used for opening beverage bottles.

With the foregoing and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be more fully described and particularly pointed out in the appended claim.

In the accompany drawings, Figure 1 is a top plan view of the invention showing a can opener attachment applied to the handle; Fig. 2 is a rear view of the device shown in Fig. 1; Fig. 3 is a transverse sectional view on the line 3 3 of Fig. 1; Fig. 4 is a transverse section on the line 4-4 of Fig. 1; Fig. 5 is a perspective view of the clamping plate removed from the device; Fig. 6 is a plan view of the device without the can opener attachment.

Referring more especially to the drawings, 1 represents the body of the device which is preferably constructed of heavy wire having the opposite legs thereof, intermediate their ends, convergent so as to form a beveled bearing surface 2 which is arranged adjacent the steel 3. The opposite end of this body is extended out into connected parallel portions 4 which form a handle for the device and upon which I preferably mount the component parts 5 and 6 of a can opener.

Adjacent the bearing portion 2, the legs of the body are extended or bulged out, as at 7, in order to provide the double bearing points a and b for the steel and prevent the latter from engaging the legs throughout its length. The outer ends of the legs are preferably turned outwardly and upwardly into the form of hooks 8 which are beveled at 9 to form engaging edges 10. These hooks while primarily formed to make bearing surfaces 11 for the guidance of the scissor blades and heavier instruments, such as cleavers, and the like, they are admirably adapted to remove the caps of bottle closures.

The legs of the body at the bearing points a and b are arranged in substantially parallel relation and the cutting steel 3 which is used, being triangular in shape, lies in between the legs with its upper edges overlapping the same and its lower conical edge projecting therethrough, as shown in Fig. 4.

In order to hold the steel in position, I provide a clamping plate 12 which is provided with a central raised ridge 13 forming a channel 14 for the reception of a locking pin 15. The plate 12 is provided with substantially V-shaped notches 16 in its ends so that when the ends are bent around the legs of the body, the edges of the notches 16 will be closely arranged, as shown in Fig. 2. The wedge 15 lies onV top of the cutting steel and clamps the same tightly between the legs so that its adjustment is assured. By removing the wedge, the steel may be adjusted or reversed or turned upon its longitudinal axis so that different edges may be brought into operative engagement, it being understood that each edge of the triangular bar is sharpened for the purpose described.

In operating the device, its lower end is placed against a table and the body held at an angle while a knife blade is inserted between the bearing surface 2 and the steel 3 and drawn through in the usual manner. When it is desired to sharpen cleavers or the like, the tool is laid flat upon the table and the Cleaver used upon each bearing surface 11. By hooking the beveled ends 9 over Vva bottle cap and using the side of the clamp 12 as a fulcrum, the cap may be readily removed and the bottle opened.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction, may be resorted to without departing from the principle or sacricing any of the advanlegs, a clamp for holding said legs in proper tages of the invention as dened in the ap=` relative position, and a Wedge engaging pended claim.
