i To all whom i i ma i concem:
Beit known that I, JASPER O. Owens, a citizen of the United States, residing at Los Angeles, in'the county of Los'Angeles 5 and State -of California,'have invented newand useful Improvements in Knives, of which the following is a specification.
This invention relates to a knife particularly adapted for the cutting. of linoleum 10 and like articles, the prime object being the provision of a strongly constructed knife in a shape adapted for this class of workand with a detachable blade. The parts of the knife are soarrangedthat the sheath sur- 15 rounding the blade forms a heavy reinforce ment for the same, the blade consequently being comparatively thin and light and ca pableof receiving and keeping a fine edge.
Ifa blade is broken it is only necessary to .20 procure a new blade instead of procuring a whole new knife as formerly. By reason of making the blade thin and containing little metal it is possible toput into its manufacture a much higher grade of steel than is' ordinarily used, and still keep the cost of the knife at a reasonable figure. Moreover, the sheath is made of a material, such as mild steel, which is not so brittle as the knife steel, being consequently much less liable to breakage and protecting the knife blade from injury.
Another feature of my device is the pro.- vision of a double ended knife, the blade being reversed in the sheath when one edge has been dulled.
In the accompanying drawings I have shown the forms preferably taken by my invention for the purpose of cutting linoleum. Minor changes may adapt it to other uses.
In the drawings Figure 1 is a side elevation of the preferred form of my invention.
Fig. 2 is a plan of the; same. Fig. 3 is .a side elevation of the knife blade. Fig.4: is an enlarged section taken on line k4; of Fig. 1. Fig. 5' is an enlarged section taken on'line 55 of Fig. 1. Fig. 6 is.a side elevation of a modified form. Fig. 7 is an enlarged section of a modified form.
In the drawings 5 designates a handle to which is rigidly affixed the sheath. Sheath 6 in the preferred form is of circular side configuration, being completely closed on its end near the handle Sand open on its other end. The back portion 7' of the sheath is enlarged in the form of a rib to inclose the bread 8 on the back of knife 9. Portion 7 of the sheath extendsdown over the beaded back-of the knife to a point close to the cutting end" of the knife blade, while the inner portions of the sheath are cut away as at 10 to expose the cutting edge of the knife blade back to the knife also being circular. The body of the knife-blade can'consequently be of uniform width and still slip easily into the sheath, its end resting against the closed end of the sheath -as is.'shown-'in Fig. 1. A small set"screw'11 bears against the knife blade, and prevents it moving out of the sheath. i
In Fig. 6 I have shown a modified form in which thesheath and blade are curved in some manner other than on the circumference of a circle, preferably on a curve flattening at the end and curving greatest 1n the center. In such a case-it. is necessary that the sheath and blade shall taper from the center the blade shall be introduced to the sheath ture of the knife is practically the same as above described.
In Fig. 7 I have shown a section'of a knife of modified form in which the bead is omitted. This form may be ,used as well as the preferred form. A
Having described my inventior'nI claim:
1. A knife, c'omprismg a handle, a thin sheath of curved configuration mounted upon the handle and closed at its end nearest the handle and open at its other end and along its inner .edge near the open end, a cutting blade of similar curved configuration and having cutting edges on its lnner edge near its ends, the blade being adapted to fit within-the sheath with one end projecting from the open end thereofv and its cutting edge projecting from the open inner edge of the sheath,-and means to hold the blade in place in the sheath.
2. A knife, comprising a hollow sheath of curved configuration, being entirely closed atone end'and beingopen at its other end and along its inner edge adjacent the open end, and a knife blade of similar curved con 2. point near, the middle of the blade. The edges of rthe sheath at 10 toward both ends in order that? A and fit snugly therein; Otherwise, the strucfiguration sharpened on its inner edge and have hereunto subscribed my name this 3rd adaptedto he slipped longitudinally into the day of January 1911. sheath, leaving one end projecting from the open end thereof and its sharpened edge JASPER OWENS' pfi'ojelclting from the open inner edge of the \Vitnesses: s eat ELWOOD H. BARKELEW, In Witness that I claim the foregolng I Com E. MONTGOMERY.
