SAMUEL ELLIOTT CREASEY, OF SANFORD, MAINE.

CORE-REMOVING TOOL.

Application filed February 6, 1918. Serial No. 215,693.

To all whom it may concern Be it known that l. SAMUEL E. (.nnnsnr, a citizen of the United States, and -a resident of Sanford, in the county of York and State of- Maine. have invented a new and Im proved (lore Renmving Tool, of which the following is a full, clear, and exact descrip tion.

Among the principal objects which the present invention has in view are to provide 'means for readily removing the core from fruit of certain characters. such as grapefruit or other citrous products; to perform the operation with despatch and neatncss; to reduce the need for handling the fruit, with the consequent soiling of the hands; and to produce a tool of the character mentioned at reduced cost.

Drawings. Figure-1 is a perspective view of a coreremoving tool constructed in accordance with the present invention;

Fig. 2- 1s a bottom end view of the same; Fig. 3 1s a longitudinal sect on, the section being bent as on the line3-3 in Fig. 2 and I Fig. 4: is a side view of a power attachment used foroperating the said tool.

As seen in the drawings the tool has a hollow tubular ,body 9 which is slightly tapered, terminating at. the lower and advancing end in sharp saw-cutting teeth 10.

- The upper end of the body 9 forms a ferrule 11 to receive a handle 12.,

Intermediate the ends of the body 9 a delivery orifice 13 is formed through which the macerated core of the fruit being operated upop is delivered. To assist the delivery reterred to an inclined shield 14 is disposed tl'ansversely of the body 9 and. is support-ethin operating position by the bandle l2. The shield 14 is rigidly and permanentl y secured to the body 9. v

To regulate the depth to which the cutting end of the tool is to operate a shield 15 is removably attached to the body. In practice one shield 15 is usually employed and, as shown in the drawings, the central perforation of the said shield permits the extension thereof over the body 9 to a position adjacent the lower end of the orifice 13. It is obvious that if it be desired to limit the in- Specification of Letters Patent.

.course relative to the atented Feb. 4, 1919.

tral opening which would engage the tapered side of the body 9 ate point nearer the cutting edge thereof.

Just inside of the tubular body 9, and disposed in an inclined position; is a cuttin blade 16. The inclination of the blade 16 the fruit. and with a revolving or rotary movement. This in the accompanying serves the added function of lifting the thereof in line with the axis of the core of depresses the said cutting edge serves to sink the cutting end of the tool into the fruit until the cutting blade 16 is brought in contact therewith, when it will be found that the lower end of the inclined blade will engage and cut the core, removing the same from the body of the fruit for delivery upward over the inclined blade adjacent the inner' wall of the tubular body 9. lVith the continued revolution of the tool the blade 16 sinks farther into the body of the fruit and the separated ormacerated portion thereof continues to pass up the incline of the blade 16, taking thereby a spiral wall of the body 9, this being in reality a straight line, due to the fact that the severed or macerated portions are not revoluble by the operation of the tool.

The operation above set forth is continued until the shield 15 engages the outside of the fruit and serves to arrest the further introduction' of the. cutting edge of the too] thereinto. At the latter end of the operation it will be found that the severed or macerated portion of the fruit, to wit, the core thereof, has been partially delivered through the orifice 13.

The tool herein disclosed -is used principally for the purpose of removing the core from grapefru1t,;and generally from a half mand-relhaving a screw-threaded portion 18 mounted in a bearing 19 on a bracket 20, the screw-threaded portion 18 engages a block :introduced in'the ferrule 11, the handle hein removed or modified in form. The bracliet 20 is intended tor use in connection with a table, bench, or other suitable supadvantageously employed for removing the cores of such fruit as the apple, pear, or

similar srvxtt-centerml or cor-ed bodies. I

1. A tool as characterized havin e hollow.

tubular body provided with a delivery orifice intermediate the ends thereof, said body having at the receiving end a series of eut-- i ting teeth; a lifting cutter rigidly mounted,

in. said bodyto extend partially across the same, said cutter being inclined to the sums of said body and l'irmided'with a straight fice intermediatethe ends thereof said body,

having at the receiving end a series of cutting teeth; a lifting cutter rigidly mounted port. When so arranged the tool is most mo est in said body to extend partially'ecross the same, said cutter being inclined to the axis of said body and providedwith a straight cuttingedge, the depressed end whereof is adjacent the plane of said teeth, said cutter being disposed toiorrn an elevating surface at the upper side thereof for lifting the material out from the body of the fruit; and a delivery shield mounted in said body adjacent the delivery opening therein for eject 0 ing the severed portions of the fruit from said tubular body. it

A tool as characterized having a hollow tubular body provided with a deiivery orifice intermediate the ends thereof, said body having at the receiving end a series of cutting teeth; a lifting cutter rigidly mounted in said body to extend partially across the some said cutter being inclined to the axis of said body and provided with a straigl'it cutting edge, the depressed end whereoi'is adjacent the plane of saidteeth, said cutter being disposed to form an elevating si'lriaee at the upper side thereof for lifting the material cut from the body of the'55 fruit; and a shield reinovably disposed on said tubular. body for regulating the depth of the insertionoi the tool in the fruit.
