-. To @ZZ whom it may] concern;

Be, it known that I, OLIVER CLARK TERRELL, a citizen ofthe United 1Statesresidingat Portland, inthe .countyof Multnomah and State of Oregon, have invented certain new and useful Improvements in a `Praring Knife, of which the following is, a specification. y y f This invention re-lates toparingknives and it-consists in the novel features herein,- after described and claimed. Y fr An object. of the invention is tofl provide a knife especially adapted to be usedfor paring fruit or vegetables of globular or substantially conical form and for `slicing the denuded bodies intot segments or sections and also for coring and pitting fruits.,

In the operation of paring fruits or vegetables it is desired that the skins be removed completely from the bodies in one continuous ribbon of the same transverse breadth, and of substantially the same transversethickness. In that the surfacesl of fruit and vegetables, irrespective of the general form of their bodies, do not lie in the same arc of curvature, it is a difficult operation to remove the skin in such form of ribbon, with a straight edge knife or with a knife having a curved edge of but onearc of curvature. Therefore, it is the object of the present invention to provide a knife blade which may be conveniently and effectufally used for removing the skin in a continuous ribbon of uniform. transverse breadth and thickness from the fruit or the vegetables irrespective ofthe irregularities which might occur in the genera-l geometrical form o-f the surface of the article.

VithA this object in view the knife includes a blade having a plane end portion and which merges into an inner portion which is formed with a succession of arcs of different magnitudes. That 1s lto say these arcs are of different degrees of curvature' and the individual arcs of the series of `arcs increase in magnitude from the plane end portion of the blade toward that end pork tion thereof upon which the handle is mounted. At a point between the arcuately shaped portion of the blade and the handle, the blade is provided with a bent portion. In use, the bent portion is 'inserted in the stem depression of the fruit, `and the skin is cut whereby the ribbon is started. During the paring operation the fruit is rotated under the respective arcuate portions o-f the blade and thecuttinglof .the ribbon is conl tinued' until the body of the fruit is completely denuded The plane end portion of the blade may thenbe used for dividing'the denuded bodyinto segments or sections.

In .the accompanying drawings V Figurelfis a perspectiveI viewl ofthe paringknife.` f f Figure 2.is a diagrammatic edge view of a fragment 'of ,the blade of the lparing knife.

blade l provided at onel end with a plane portion. The inner end ofthe plane portion 2 mergesintoanarcuate portion 3, the arouate portion 3 merges into an arcuate portion f e, and rthe arcuate portion 4 merges into an arcuate portion 5. The cords of the arcs 3, 4: and 5 lare substantially of the same length. Of the series of arcs the curvature of the arc 3 is least, the curvature of the are a is deeper than the curvature of the arc 3 and the curvature of the are 5 is deeper than the curvature of .the arc 4E. Thus the arcs inc-reasein degrees yof curvature from the plane portion 2 but as hereinbefore The paring knife comprises a: Spatulate 5" stated the cords of the said aros are substantially of the same length. The arc 5 vmerges intofan irregular curve 6 which forms one-side of an arcuate Vbend 7 provided in the blade l. From the bend 7 the blade .is continued into a side 8 which is disposed opposite the irregular curve 6 or which is inclined toward the said irregular curve 6. Handle strips 19 are applied to the opposite side of the blade. l beyond the side portion 8. y f 1 In use the bend 7 is inserted in the stem depression of the body, fruit orvegetable,

and the said body is turned with relation to the blade in a usual manner. Theirregular curved portion 6 removes the skin from the wall of the depressionfin the` body and starts the ribbon. n As the flatter portions of the surface of the body are brought toward the bladek the body is worked along the blade so that the different arcs 5, 4 and 3 are brought under the skin of the body.

Thus the ribbon which is removed from .the

body will be substantially of the same transf versebreadth in that the cords of the arcs ythe body has been completely denuded it may be cut'into `sections or segments in a usual manner by using the plane end portion 2 of the blade.

Vith the sharp curved edge 7 the eyes may be removed from potatoes and the green circles may be cut out of parsnips and the parts of the cores may be removed from slices of apples, pears and quinoes and the like, and Without gouging into the fruit. The blade may notl only'be used for removing the skins from fruit of every description but may be used for slicing the fruit and.v removing the seed and pits from the slloes 1n an efficient manner. The curves 5,

G and 7, and the side portion 8 of the blade may be used for eoring and seeding and for removing the cores and seeds from such fruitr as apples, pears, quinces and the like. The curves 6, 7 and 8 may be used to advantage for removing the eyes from potatoes in an eiifcient manner.V The blade may also be used to advantage for slicing and paring such fruit as peaches, plums, prunes, apricots and other fruitspreparatory forV drying and for removing the. pits or seed from such fruit.

Therefore it will be seen that each curve and each straight edge in the knifel blade structure may perform its special function and purpose in slicing and paring fruit and vegetables.

Having thus described the invention, What I claim is:

l. AV paring knife blade having a plane end portion which merges into a series of successive and joined arcuate portions, the cordsV of eacharc of the arcuate yportions being of the same length andthe arcs gradually'increasing in depth from the plane end portion.y 'Y f 2. A paring knife blade having a plane end portion which merges into a series of arcuate portions, the arcs of curvature of the said arcuate portions being of thesanie length and the arcs of curvature of thearcuate portions being of different depths, and the said arcuate) portion ,merging into a return bend portion-havingspaced 'side Walls.v f l Intestilnony whereof I affix' my signature.
