Description

Patented Mar. 8, 1932 UNITED STATES FRANK YAHN, F ST. PETERSBURG, FLORIDA FRUIT COREB.

Application filed February 2'?, 1931. Serial No. 518,808.

Another object is to provide such a device with several sizes of cutters for use in coring different sizes of fruit.

A further object of the invention is to provide a core remover which will lift the core bodily from the fruit, one from which the core can be readily extracted and which can be readily dismantled for cleaning.

Other important objects and advantages of the invention will become apparent during the course of the following detailed description when read in conjunction with the accompanying drawings, which form a part of this specification and in which:

Figure 1 is a side elevation of a corer embodying my invention;

Fig. 2 is a bottom plan view thereof;

Fig. 3 is a sectional view taken on the line 3-3 of Fig. 2;

Fig. 4 is a sectional view taken on the line 4-4 of Fig. 3 f

Fig. 5 is a view similar to Fig. 3, but showing different sized cutter;

Fig. 6 is a bottom plan view of a modified form of the invention; and

Fig. 7 is a sectional view taken on the line 35 7-7 of Fig. 6.

Referring now more particularly to the drawings, wherein like numerals refer to like parts throughout the same, 10 indicates a handle which may be made of wood or any 4 other suitable material and the'grip portion of which may take any desired form. The handle 10 terminates in a circular base portion 1l, the outer face of which is rabbeted as at 12 to form an annular shoulder 13.

A cylindrical cutter member 14 has one end received within the rabbeted portion 12 and over the shoulder 13 las clearly shown in Figs. 5 and 7. If desirable suitable fastening means such as a pin and bayonet slot maybe 5o employed to lock the cutter to the handle, but

a frictional engagement has been found satisfactory. The edge of the free end of the cuttgr member 14 is suitably sharpened as at 1 For the purpose ofV aiding in the lifting of the core from the fruit, a pointed pin 16 is provided. The pin 16 extends at an angle` from the low-er face of the base 11 and within the space enclosed by ythe cutter 14. An angularly disposed socket '17 is formed in the base so that the pin can be readily inserted therein or extracted therefrom. The pin preferably extends a short distance below the edge of the cutter and the pointed end thereof 1s also spaced inwardly from said edge.

In order to provide forthe accommodation of cutters of lesser diameter when operating upon smaller fruit, the base '11'is provided with an annular recess or socket 18 in the lower face thereof, producing an annular shoulder 19 which forms a seat for the end of a cylindrical cutter 20. A pointed pin 21 similar in construction and relative arrangement to the pin 16 is removably disposed in an angular socket 22 when the cutter 20 is to be used. In practice only one pin is actually needed,'the same being transferred from one socket to another depending on'the cutter to be used.

In the form of the invention shown in Figs. 6 and 7, instead of using a single

diagonal pin

16 or 21, I employ a plurality of vertically disposed pins 23 centrally grouped with respect to the cutters and adapted to penetrate the core. In this form, the handle 24 is identical in construction to the handle 10 except that the sockets for the pins 23 are parallel with the sides of the cutters.

In the operation, the cylindrical cutter of correct size is placed on the handle and thev pin inserted in the appropriate socket. The cutter is then placed over the end of the core and pressed down to sever kthe sides of the core from the fruit, the pin meanwhile penetrating the body of the core. When the cutting edge has reached the rind or skin around the core, the device is rotated so as to twist the end of the core free from the rind, whereupon the corer carrying the core is lifted Vfree of the fruit. The cutter is then removed from the handle and the core discarded. By making the cutters removable from the handle, cleaning of the device is greatly facilitated Which is very important when coring grapefruit and oranges.

The operation of the Inodiied form of the invention is substantially the same as above except the pins do not have to be changed t0 accommodate different sized cutters.

Although a preferred embodiment of the invention has been shown and described, it Will be understood that changes in the details of construction may be made Without departing from the spirit of the Ainvention as defined by the appended claims.

v I claim:

l( A corer .comprising a cylndricalcutter and a pin member extending substantially entirely through the bore of said cutter and diagonally thereof.

"2. A corer comprising a handle, a cylindr'calcutter element carried thereby, and a plurality of pin elements extending longitudinally of and substantially entirely t through the bore of said cutter.

' 3. A corer comprising a handle having a circular base, an annular shoulder for-med with said base, a cylindrical cutter having one end received on said shoulder and the other end sharpened, and a diagonally eX- tending pin element carried by said base and extending into the bore of .said cutter for substantially the length thereof.
