3 Claims.

My present invention relates to the art of kitchen utensils and more particularly to a gauge paring knife.

Many attempts have been made in the past to lind a paring knife having a guard or gauge member which lessens the danger of cutting ones self on the knife blade itself and fiuther permits more rapid use of the knife in that a'gauge is provided which limitsithe depth the knife can cut. Applicant is well aware that many attempts have been made in the past to provide such a par ing knife. However, there are several considerations which must be duly weighed in the production of a utensil of this order. First, and probably most important, is the necessity of providing a knife which will be cheap to make so as to make the articles saleable in the face of low priced competition. Some attempts have been made in the past to provide a gauge paring knife formed of rolled material which is rolled around the end of a handle or itself provides the handle; for structural reasons this is a very fine design. However, most such constructions fail as an article of manufacture in that, in order to provide suitable material for the cutting edge itself, it has been necessary to make the entire metal portion of material too high priced to make the article saleable in the face of present competition or the entire device suffers because of cheap material. In the present instance the applicant has endeavored to make use of the structural advantages of the rolled or tubular type paring knife and to supply this knife with a cutting edge of suitable material while leaving the frame work of the knife proper of material suitable for the purpose but not of the expensive character which a keen cutting edge requires.

Therefore the principal object of the present invention is to provide a gauge paring knife wherein the actual cutting edge is an inserted piece of high grade steel made of better material than the frame work of the knife proper.

A further object of the present invention is to provide a paring knife in which, additional new blades can easily be inserted by an inexperienced person.

A further object is to provide in a knife of the character described, a reversible or double edged knife so that if one edge becomes damaged another one is available for immediate use.

A still further object of the present invention is to provide a blade of material different from theframe work proper and which is so arranged that it may be reversed so as to 'provide not only a gauge paring knife but a slicing implement as well.

' Other and more specific objects `will be apparent from the following description taken in con- Figure 1 is a perspective view showing my knife as applied in the peeling of an apple.

Figure 2 is a longitudinal View of my knife a portion of which is shown in section.

Figure 3 is a longitudinal View, partly in section, of my knife.

Figure 4 is a cross sectional view along the line 4-4 of Figure 3.

Figure 5 is a perspective view showing one desirable type of blade for use with my knife.

Figure 6 is a fragmentary perspective view partly in section to more completely illustrate the construction I wish to employ.

Referring to the drawing, throughout which like reference characters indicate like parts, I6 designates a rolled type of sheet metal paring knife which is intended to be secured to normally a wooden handle as I8. It will be apparent it is believed that if the tubular portion of member I8 as 20 were to'be extended it would in itself provide a suitable handle. This may be desirable in certain instances. The knife frame work i6 is formed of a substantially tubular shape with a portion of the same removed but providing a tip portion as 22 which is curved in conformity with the tubular form of base 20.

It has been found most convenient to curve, by suitable pressing, the portion intermediate between collar 20 and tip 22 to the end that a curved surface may be more closely peeled. This is shown in perspective in Figure 1 as applied to an apple and the curve of the cutting blade 24 should approximate as nearly as possible to the average curvature of the fruit or vegetable it is intended to pare. In this way a relatively wide peeling P can be removed from any fruit or vegetable instead of the usual narrow peeling which is removed with the ordinary straight blade. This being accomplished with the curved blade without cutting too deep into the fruit or vegetable and thus wasting the same.

Member I6 is normally made of cheap material of rather light gauge preferably of stainless material but of material which is relatively inexpensive and by having the tubular form the minimum thickness of material can be used and still retain the rigidity essential for this type of knife.

It is then found desirable to form the cutting edge as knife blade 24 of material which can nection with the accompanying drawing, where'- 'L Cil easily be sharpened and which will retain its keen edge for a long period and when damaged can normally be replaced with a new blade without discarding the entire knife. Possibly the simplest manner of attaching knife blade 24 is by providing recesses as 26 and having the knife blade 24 provided with outwardly extending lug portions as 2S to engage these recesses. Now the material of which blade 24 is made should be fairly flexible and it has been found that the two ends of the bowed blade 24 can be placed in the recesses 26 and then by springing the blade downwardly past the line joining the two recesses 26 the blade will snap into position.

As seen in Figure ll, the blade 24 is held securely in position by a backing or stop ledge 3Q. Then it is desirable to indent the tubular portion as at 32 to provide a space 34 between gauge member 32 and the knife blade 24. The extent of this opening determining in a large degree the depth to which the knife will cut. It is then further desirable to further distort the tubular arrangement at S5 so that a relatively easy entrance of the knife into the fruit or vegetable will be possible.

In Figures 2 and 3 I have shown the paring knife as provided. with a wooden or composition handle ES which is composed of a male portion 52 and a female portion` 54. Secured wit-hin the female portion I provide in the illustrations a coring device as 5@ and provide within member 52 a socket as 58 of suicient depth to accommodate this coring device. It may be desirable to substitute for this coring device a hat or curved paring knife blade of any desirable type.

It is believed that it will be apparent that, following the principles outlined, if it were desirable to produce the cheapest possible type of paring knife, blade 24 might be Xedly secured within the tubular portion I6. This could be accomplished by riveting the same in place or by spot welding or even soldering the blade in position. This would destroy the inter-changeability of blades but it would naturally provide an article of merchandise that could loe offered to the buying public at the very lowest prices.

The foregoing description and the accompanying drawing are believed to clearly disclose a preferred embodiment of my invention but it longitudinally curved walls in said holder, of an arched blade of resilient material, retaining lugs forming shoulders at the opposite ends of said blade and transversely extending slits at the opposite ends of said opening to receive said lugs and shoulders, and said holder having an inturned portion at one longitudinal edge of the opening forming a gauge for the cutting edge of the blade.

2. In a paring knife having a handle, a tubular frame portion, an extension curved in cross section forming a blade holder and an opening in said holder having longitudinally curved walls, and a pointed tip on said extension, or a cutting blade of resilient material, means for detachably mounting said blade in the holder adjacent the opening, and an inturned concaved longitudinal wall of the opening forming a spaced gauge for the cutting edge of the blade.

3. In a paring knife, the combination with a blade holder of sheet metal, curved in cross section and provided with an opening therein, said holder being curved longitudinally to forni concave walls at opposite sides of the opening and transversely arranged arcuate slits in the opposite end walls of said opening, of an arched blade oi resilient material, end lugs on said blade projecting through said slits and forming end shoulders engaging the walls of the slits whereby the blade is retained in arched position, and said holder having a depressed inturned edge along one longitudinal side of the opening forming a gauge for the cutting edge of the blade.
