PEACH-FITTING TOOL.

Specication of Letters Patent.

Patented Apr. 12, 1921.

Application led January 28, 1919. Serial No. 273,590.

To all iw hom it may concern Be it known that I, SAMUEL J. DUNKLEY, a citizen of the United States, residing at Kalamazoo, Michigan, have invented certain new and useful Improvements in Peach-Pitting Tools, of which the following is a specilication.

This invention relates to improvements in peach pitting tools.

The main object of the invention is to provide a simple and effective rotary cutting tool for the cutting' out of pits from cling stone peaches, although the tool is adapted for various purposes, and can be very well used for taking the cores from pears and apples.

Objects relating to details and economies of construction and operation will appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specii'ication. The invention is clearly defined and pointed out in the claim.

A structure which is a preferred embodinient of my invention is fully illustrated in the accompanying drawing forming a part of this speciiication, in which:

Figure I is a longitudinal central sectional view through a tool embodying the features of my invention, the driving shaft and some of the gears and other parts being shown in full lines, the same being taken on a line corresponding to line 1-1 of Fig. II.

Fig'. II is a detail transverse sectional view on line 2 2 of Figs. I and V, the gears, shafts and cutting tools being shown in full lines.

Fig. III is a detail view of the Spanner wrench for removing and inserting the gears for cleaning and inspection.

Fig. IV is a detail view of a modification of the cutter.

Fig. V is a detail view of the tool 1nodi fied for support in a vise or clamp'to permit the operator to use both hands in handling the fruit.

F ig. VI is an enlarged detail view of a modification of the knife 14, showing the serrated edge.

In the drawings the sectional views are taken looking in the direction of the little arrows at the ends of the section lines and similar numerals of reference refer to similar parts throughout the several views.

Considering the numbered parts of the drawing, 1 is the handle, on which is supported the detachable head 2, the same being provided with a screw thread connection 3 with a bushing 6 which provides a journal bearing for the driving shaft 4. A suitable bushing connection 5 is provided for the flexible shaft 7 at the opposite end of the handle.

A beveled gear 8 is provided on the end of the shaft 4 and intermeshes with a gear 9 which drives the revoluble cutter 14. A removable plug 10 carrying a sleeve 11 is provided to support the tubular shaft 13 which carries the cutting tool 14. The cutting tool 14 is hollow and conical in form with the outer sides beveled at 14 as indicated. The tool is provided with a shank l5 from the conical tip end which is inserted into the tubular shaft 13 and retained there by a set screw 16, as clearly appears in Fig. I.y The tool is readily removed by withdrawing the screw 16. The entire head can be disassembled for cleaning and inspection by using the Spanner wrench 17, as the parts are readily removable for cleaning and lubrication.

In Fig. IV, I have indicated a modification of the cutter. The same is still of the conical form with the beveled cutting edge, with portions cut away at 19 to permit of the ready passing of the debris, such as halved pits or the parts of the core of any fruit.

It is sometimes desirable for instance where fruit is large or is particularly tough for the operator to use both hands, in which event I provide the handle with a suitable squared portion 20 which can be supported in a clamp or vise 21 as indicated in Fig. V. It may of course have any suitable support.

I have shown my improved pitting and coring tool in its most approved form, but desire to state that it can be considerably varied in details without departing from my invention. .Vhile it is desirable that this cutter be disposed in transverse relation as indicated, it of course might very readily be supported on the end of the shaft and the intermediate gearing be avoided. As this is such an obvious expedient, I have not deemed it necessary to illustrate it.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

In a pitting or coring' tool, the combinetion of a, suitable handle, anV axially disposed driving shaft therein, e heed on the handle with e transversely disposed shaft, a hollow conical cutting tool With shank from the apex and with peripheral cutting edge beveled from the outside carried by the seid driven shaft, coacting substantially as de- 10 scribed for the purpose specified.

In Witness whereof, I have hereunto set my hand and seal in the presence of two Witnesses.
