KNIFE SHARPE APPLICATION FILED AUGJI. l9"- (r/je 5. WedVlf 4* Is {my Patented Aug. 12,1919.
CHARLIE B. WEAVER, OF LOS ANGELES, CALIFORNIA.
KNIFE-SHARPENER.
Application filed August 21, 1917.
To all whom it may concern:
Be it known that I, CHARLIE B. WEAVER, a citizen of the United States, residing at IJOS Angeles, in the county of Los Angeles, State of California, have invented new and useful Improvements in Knife-Sharpeners, of which the following is a specification.
This invention relates to a device for sharpening knives and the like; and relates particularly to devices characterized by, a cutter against which the knife blade is drawn by longitudinal movement to sharpen the blade. It is a general object of this invention to provide a simple device which may be readily attached to a sharpening steel, file, stone, or the like, and may be readily used to sharpen a knife blade. It is an object to provide such a sharpener in a convenient ready form so that a knife blade may be and will be quickly and easily sharpened whenever it is used.
The features of my invention will be best understood from the following detailed description of a preferred form of device reference being had for this purpose to the accompanying drawings, in which Figure 1 is a view of a sharpening steel equipped with my sharpening device; Fig. 2 is an enlarged side elevation taken as indicated by line 22 on Fig. 1; Fig. 3 is a similar elevation taken as indicated by line 33 on Fig. 1; Fig. 4: is a section taken on line 41-4 of Fig. 2; Fig. 5 is a section taken on line 5-5 of Fig. 2; Fig. 6 is a perspective view of the cutter which I utilize in my device; and Fig. 7 is a longitudinal section taken as indicated by line 77 on Fig. 5.
In the drawings the numeral 10 may designate the blade of a sharpening steel and 11 the handle thereof. This sharpening steel may be of any design or character, and the steel itself may be either smooth or roughened. I provide a holder. or clamp 12 which may preferably be in the form of a band encircling the steel 10, although not necessarily of such particular form. Without limiting myself to such form, I describe this holder 12 as being in the form of a ring or band of metal as shown at 13 with an offset socket portion 1-1 adapted to hold the lower end of the sharpening cutter 15. This sharpening cutter 15 is formed preferably as shown in Fig. 6, being made of a triangular piece of steel with three sharp cutting edges 16, any one of which may be used. Or the sharpening cutter may have more Specification of Letters Patent.

than-three edges; for instance, it may be square instead of triangular. The lower end of the cutter has its corners beveled away as shown at 17, forming tapered or beveled surfaces at 17 adapted to bear against the surface of the steel 10. The lower end of the cutter 15 is inserted in the socket 1 1, which is made of proper configuraserted between the band and the steel.
The fact that surface 17 bears against the steel 10 throws the cutter 15 out at a slight angle to the surface of the steel 10. This angle is made to correspond to'the proper average edge angle of a knife blade.
By proper reference to Fig. 7, it will be seen that the cutting edge 16 runs right up to the surface of steel 10 at a point somewhat above the clam) 12. In other words, the angular opening between the cutter and the steel narrows down to a very fine point; so that the knife blade may be very finely sharpened. The cutter 15 is readily removable by loosening the clamp so that any one of the edges of cutter 16 may be used. When all the cutting edges 16 have become dulled then the cutter may be easily sharpened by slightly grinding its flat faces; or these cut ters may be provided so cheaply that a dulled cutter may be discarded and replaced with a new one.
In using my device the handle 11 is held in one hand and the knife in the other and the knife blade is merely drawn longitudinally through the angular opening between cutter 15 and steel 10. The sharp edge 16 of the cutter sharpens the knife blade on the side next the cutter. The knife blade is drawn through first one way and then the other, so as to draw both edges of the knife blade against cutter 15. A few strokes will usually suffice to keep the knife in proper sharpened condition if the knife is sharpened at frequent intervals. WVith my device conveniently at hand a knife will be sharpened at more frequent intervals than if the sharpening device were not conveniently at hand. The edge of the knife blade having been sharpened it may be finished by drawing it in the usual manner over the steel 10. It will thus be seen that my device is very conveniently used; with the result that knives of all kinds; butcher knives, table carving knives and the like are all kept with a much better edge than would otherwise be the case.
I have described in particular a specifically preferred form of my invention; but I do not thereby limit my invention thereto, believing my invention to be. broad in its nature within the scope indicated and set forth by the following claims:
Having described a preferred form of my invention I claim:
1. In combination with a sharpening steel or the like, a blade sharpening cutter clamped against the side of the steel at an angle so as to leave an angular opening between the cutter and the steel through which opening a blade may be drawn with the opposite sides of its cutting edge in contact with the cutter and steel, respectively.
2. In combination with a sharpening steel or the like, a clamp encircling the sharpeningsteel, said clamp having a socket, and a blade sharpening cutter mounted in said socket and held by the clamp against the sharpening steel at an angle thereto so as to leave an angular opening through which a blade may be drawn with the opposite sides of its cutting edge in contact with the cutter and steel, respectively.
3. In combination with a sharpening steel or the like, a clamp encircling the steel and having a socket at one side, and a blade sharpening cutter held in said socket, said cutter having at its lower end a diagonal edge pressed by the clamp. against the steel so that the cutter is held at an angle to the surface of the steel.
4. In a device of the character described, a sharpening cutter having a longitudinal cutting edge and a mounting surface on one efid of the cutter at an angle to the cutting e ge.
5. In a device of the character described, a sharpening cutter, prismatic in form and having a plurality of longitudinal sharp cutting edges, the edges of the cutter being beveled away at one end to form a mounting surface at an angle to the cutting edges.
In witness that I claim the foregoing I have hereunto subscribed my name this 14th day of August, 1917.
