7 Claims.

This invention relates to a tool for paring and coring fruits and vegetables, having a blade movably connected with a handle and adapted to swing automatically in substantial alignment with the line of engagement desired for uniformly peeling an article of irregular contour and being capable of such movement without wrist-turning action on the part of the operator.

It is an object of this invention to provide a device of this character that is inexpensive to manufacture yet is durable and of pleasing design.

With the abov and other objects in view, as will be apparent, this invention consists in the construction, combination and arrangement of parts, all as hereinafter more fully described, claimed and illustrated in the accompanying drawing, wherein:

Fig. 1 is a side elevation of a paring'and corstamped preliminary to forming a sleeve for receiving and engaging the extension of the blade aforesaid within a suitable handle.

Fig. 5 is a side elevational view showing the sleeve of Fig.4 in final form.

Fig. 6 is an enlarged transverse section taken 3 on line 6-6 of Fig. 1.

Fig. 7 is an enlarged transverse section taken on line 'l-'l of Fig. 1.

Fig. 8 is a fragmentary side elevational view of a modified form of handle extension.

Fig. 9 is a plan view of a modified form of sleeve for cooperation with the type of extension shown in Fig. 8.

Fig. 10 is an enlarged end view of the handle extension and sleeve assembly embodying the features of the elements shown in Figs. 8 and 9.

Referring first to the structure illustrated in Figs. 1 to 3, inclusive, the numeral I0 indicates a blade having parallel side edges H and I2, and an end extension [3 which, when bent, will form a tubular structure or journal. The blade l0 and extension l3 are preferably formed from an integral blank of sheet metal or the like with the sides of the blank recessed as at M to provide a relatively narrow shank or neck portion intermediate the blade portion It: and the extension I3 To complete the formation of the blade, a slot I6 is cutlengthwise of the edgesll and [2 oi the blade and is. disposed centrally thereof, to define edges IT and I8 which are preferably sharpened to provide cutting edges as contemplated by this invention wherein either of. said edges coacts with the other as a guard in leading relation to cutting edge during operation of the blade. In order to dispose the cutting edges l1 and I8: of the blade It] in operative relation. to

the surface of an article to be cut or pared there by, the edges II and I2 of the blade are bent. inwardly toward each other to. create a transversely arched blade structure. The shank portion- I5 is also bent as at 20 in Fig. 1 to align the cutting edges l1 and I8 with the longitudinal axis of the extension l3.

Referring now to Figs. 4-and 5, as well as Fig. l, the numeral 2| indicates a flat blank of metal stamped to form parallel edges which, when bent, will form a tubular sleeve or bearing within which the extension I 3 of the blade I llmay freely turn. The sleeve 2!- isadapted to be seated in the central bore 22 of'a handle 23of suitable design and construction. A ferrule 24 of desired shape and style may be fastened to the forward end of the handle and through which the extension l3 of the blade l0 must pass to enter the handle. To aid in holding the sleeve 21 firmly in the body of the handle 23 defined by the limits of the bore 22, a barb'25 is preferably formed integrally with the sleeve 2|. Thus when the sleeve 2| is driven into the bore 22 of the handle, the point thereof projecting toward the blade ID will be in a position to embed itself in the handle under any influence tending to Withdraw the sleeve 2| therefrom.

In order to prevent longitudinal movement of the blade I 0 with reference to the handle, and also to limit rotation of the blade l0 within predetermined limits of movement consistent with eflicient paring or peeling action of the cutting edges I1 and I8, an ear or lug 26 is struck inwardly from the body of the sleeve 2| for reception in a transverse slot 21 cut in the body of the extension l3. As shown in Fig. 6, the end edges of the lug 26 thus serve as stops against which the edges of the slot 21 parallel to the length of the extension l3 may be engaged to limit for and aft movement of the blade relative to the handle.

Figs. 8, 9 and 10 illustrate an extension on the blade corresponding to the journal I3 of Figs. 2 and 3, and a sleeve corresponding to the It will be understood that changes may be i made in details of construction and arrangement of parts without departing from the spirit and scope of this invention. Accordingly, this in vention is not limited to the exact structure or structures shown and described hereinbefore,

except as defined by the appended claims.

What is claimed is:

1. In a paring tool, a handle, a blade comprising a sheet metal blank stamped to create a transversely arched body and a tubular extension projecting longitudinally from one end thereof, means providing a cutting edge and a guard edge in spaced relation thereto including a sharp edged slot extending centrally and longitudinally of the outer side edges of said blade, means for engaging and mounting said blade for pivotal movement of the cutting edg relative to said handle about an axis concentric with the longitudinal axis of said handle including a sleeve extending axially inwardly from the toolward end .of said handle adapted to cooperate with said tubular extension, and a transverse slot in said extension presenting stops for engaging a member projecting inwardly from the body of said sleeve to limit axial and pivotal movement of said tubular extension relative to said sleeve.

2. In a paring tool, a handle, a blade comprising a sheet metal blank stampedto create a transversely arched body and a. tubular extension projecting longitudinally from one end thereof, means providing'a cutting edge and a guard edge in spaced relation thereto including a sharp edged slot extending centrally and longitudinally of the outer side edges of said blade, means for engaging and mounting said blade for pivotal movement of the cutting edge relative to said handle about an axis concentric with the longitudinal axis of said handle includ ing a sleeve extending axially inwardly from the toolward end of said handle adapted to cooperate with said tubular extension, and a transverse slot in said extension presenting stops for engaging a member projecting inwardly from the body of said sleeve to limit axial movement of said tubular extension relative to said sleeve.

3. In a paring tool as described in claim 2, means for engaging and mounting said sleeve against axial movement relative to said handle.

4. In a paring tool as described in claim 2 means for engaging and mounting said sleeve against axial movement relative to said handle including a barb extending outwardly from said sleeve.

5. In a paring tool, a handle having a central bore extending axially inwardly from the toolward end thereof, a sleeve seated in said bore,

a blade having a shank extending longitudinally from one end thereof journalled in said sleeve, and interlocking means on said shank and sleeve for; limiting axial and pivotal movement of the shank in said sleeve.

, I 6. In a paring tool, a handle having a central bore extending axially inwardly from the toolward end thereof, a sleeve seated in said bore, a blade having a shank extending longitudinally from one end thereof journalled in said sleeve, and means for limiting axial and pivotal movement of the shank in said sleeve including a transverse slot in said shank presenting stops for engaging a member projecting inwardly from the body of said sleeve.
