EDGAR S. HARPST, OF TYLER, TEXAS.

FRUIT GORING AND HALVING MACHINE.

SPECIFICATION forming part of Letters Patent No. 393,154, dated November I 1888.

Application filed July 17', 1853. Serial No. 280,136.

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to improvements in fruit cutters and eorers, the object being to provide a machine that will, when cutting the fruit, core such fruits as apples and stone such fruits as peaches; and it consists in the construction and novel combination of parts, as

hereinafter described, illustrated in the accompanying drawings, and pointed out in the appended claims.

In the drawings, Figure lis a side elevation of my improved cutter complete, partly in section. Fig. 2 is a horizontal section on the line a7, Fig. 1. Fig. 3 is a detail end view of the knives H. Fig. et is a section on the line x x of Fig. 3. guide-plate.

Referring to the drawings by letter, A designates the base-plate of the machine, having an aperture,A, therein, and a a vertical standard rising therefrom, which standard is slotted at its top and provided with the horizontal arms B, extending from its upper end, which arms are united at their outer ends by the vertical guide-sleeve b, open or slotted vertically between said arms.

C is arack-bar moving in said sleeve and having upon its lower end the cup-shaped follower-cap c, provided with the inwardly-standing parallel arms c.

D is a guide-plate lying against the face of the standard and having its lower end passing through a guide-opening, cl, in the base-plate at the foot of the standard. The shank d at the top of said plate is provided with a series of perforations, d2, near its upper end, through which perforations the said shank may be pivoted by the pin d3 at different heights between the arms e of the cap c.

E E are vertical guidegrooves in the outer face of the guide-plate D, which grooves are Fig. 5 is a detail face view of the (No modul.)

curved inward at their middle portions so that they meet at their centers. The said grooves perform a function hereinafter described.

F is a segmental rack journaled in bearings at the upper ends of the standard and meshing withthe rack-bar C, andf is ahandle projecting outward from the segmental rack. It is evident that when the handle is depressed the rack-bar and cap will be lifted, and will consequently lift the guide-plate D.

G G are vertical knives facing each other at a suitable distance apart. The said knives are bolted or otherwise secured to the base-plate below the cap c, and have their cutting-edges g at their upper ends rounded downward and outward.

H H are similar-knives curved laterally with their eonvexities outward and with their upper ends curving inward to their edges, which stand upward.

7L h are ears at suitable points on the opposite edges of said knives, through perforations in which ears the knives H H are pivoted upon pins h2, standing inward at opposite points from the inner edges of the knives G G.

h3 h3 are transverse edges or projections standing from the lower ends of the edges h of one of the blades H.

I I are arms standing inward from the lower ends of the blades H, and provided on their ends with anti-friction rollers i, that enter the grooves E of the guide-plate D. It is evident that as the said plate is caused to descend by lifting the handle f the guide-grooves E, on account of their central inward bends, will move the ends of the arms I first toward each other and then away from each other, thus moving the edges h of the blades H away from and toward each other.

The operation of the machine is as follows; A fruit such as a peach being placed above the knives, the cap c is made to descend thereupon by lifting the handle f, and as the handle is further lifted and the cap further depressed the peach is driven upon the upstanding edges of the knives G, and is divided in half thereby IOO rollers i, separate the edges 7L of the knives H, so that they pass on opposite sides of the stone of the fruit, and when the fruit has passed .farther down the said grooves close the knifeblades G, so that the peach is divided in hall" and stoned simultaneously. In such fruits as apples the core is removed in the same inanner.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

l. In a fruit-cutter, the combination of the pivoted knives having laterally-concaved facing sides and curved inward to the edges at their upper ends, the arms extending from one side of said knives near their lower end, and the verticallynxoving guide-plate provided with the longitudinal guide-grooves parallel at their upper and lower portions and curving inward tomeet at their centers, into which grooves the ends of said arms en ter for the purpose of opening and closing said knives, substantially as and for the purpose specified.

2. In a ruitcutter, the combination, with the vertically-reciprocating follower-cap, of the vertical iiat knives having cutting-edges at their upper ends, the concave knives H, rounded inward at their upper ends to their edges 7L, pivoted through their perforated ears upon pins standing inward from said vertical knives, and one of which is provided with transverse cutting-edges h3, the arms I, standing from said knives, the anti-friction rollers z' on the ends of said arms, and the guide-plate D, having its shank attached to arms standing from the follower-cap, passing into the guideopening cl in the base-plate of the machine, and provided with the guide-grooves E, into which the anti-friction rollersz' enter, substantially as specified.

3. The herein-described fruit-cutting machine, comprising the base-plate A, provided with the aperture A and guide-opening d, the standard B, the sleeve b, uniting arms standing horizontally from the top of the standard, the vertical rack-bar, the follower-cap on the lower end of said rack-bar, the segmental rack F, having the handlef and meshing with the rack-bar, the guide-plate D, having its shank adjustably attached to arms extending from the follower-cap by means of a pin and a series ofadj Listing-openings, and provided in its outer face with the guide-grooves E, the vertical iiat knives G, secured to the base-plate and having rounded cuttingedges g at their upper ends, the concave knives H, pivoted through.

perforated ears to pins standing from the inner edges of the vertical iiat knives, the arms I, standing from the concave knives, and the anti-friction rollers z' on the ends of said arms entering the guide-grooves E, substantially as speciied.

In testimony whereof I ai'iix my signature in presence of two witnesses.

EDGAR S. HARPST. Witnesses:
