FRUIT-PITTEFL- SPECIFICATION forming part of Letters Patent No. 276,365, dated April 24, 1883. Applicationfiled January 2, 1883. (Model) To all whom it may concern Be it known that I, CHARLES A. GURRAN, of Albany, in the county of Linn and State of Oregon, have invented certain new and useful Improvements in Fruit-Fitting Machines; and I do hereby-declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form partof this specification,in which- Figure 1 is a front elevation of the machine, showing the plunger and knife up. Fig. 2 is a detail showing the plunger down. Fig. 3 is a vertical cross-section taken in the plane in dicated by dotted line as w on Fig. 1. Fig. 4 is a view showing the pit-knives, which are attached to the hinged section of the bed.

This invention relates to certain novel improvements on fruit-pitting machines; and the nature of my invention. consists in a vertically-reciprocating plunger bearing a dividingknife, a cup-shaped fruit-holder formed of two hinged sections, and a tripping-hook for tiltingpone of said sections to discharge the pits; also, in combining with saidcup-shaped holder two knives, which will cut the skin of the fruit, so that the pits will pass out without bruising the fruit; also, in novel means for actuating the plunger and the dividing-knife, all of which will be fully understood from the following description, when taken in connection with the annexed drawings.

A designates the base of the machine, which is constructed with a narrow extension, B. This extension has hinged to it a section, B, and the two are bored out so as to form a hemispherical cup or fruit-holder, a, through the bottom of which is a hole, I), for allowing the discharge of the pits. It will be seen that one half of thecupais formed in the extensionB and the other half in the section B; also, that this latter section-is hinged at its upper edge to the extension B. If desired, the cup a may be lined with a vitreous substance, or any other substance which will not corrode.

. G C designatetwoknives,which are secured by pivots to the inner face of thesection B, and which are so arranged that they will cut through the skin of the fruit and allow the pit to be discharged without bruising the fruit.

The knife 0 is acted on by a spring, I), which allows it to yield during the act of discharging the pits.

D designates a standard having an overhanging arm, 1). This standard and its arm afford bearings for a horizontal oscillating shaft, E, bearing on one end abalance-wheel, F, which may be provided with a crank-handle for turning it by hand; but I prefer to turn this wheel by means of a treadle. This is of fected as follows: The wheel F has a grooved periphery, in which is applied a treadle-rope, F, which is secured at one point to the rim of this wheel. On the shaft E is coiled a spiral spring, Gr, one end of which is secured to this shaft and the other endis secured to the standard D. When the treadle is depressed the wheel and its shaft will be turned in one direction, and when the foot is released fromthe treadle the spring G will turn the wheel and its shaft in. the opposite direction. A spurwhee], H, is keyed on the shaft E, which engages with a vertically-movable rack-bar, J, that works in guides c c on the arm 11). To the lower end of the bar J is rigidly secured a double-beveled knife, K, for dividing the fruit, and over this a cup-shaped plunger, L, is looselyapplied, which is partly split vertically and held down on the back of the knife M by means of a coiled spring, N.

P designates a spring tripping'hook, which is secured to the rack-bar J, and which is designed for tilting the section B at every upward stroke of the said bar and its plungerby engaging with a hp, 0, on the said section. When the section B is released from the hook P a spring, S, will return this section to a position for receiving the fruit.

When fruit is put into the cup at and the wheel and shaft are turned in the direction indicated by the arrow on the drawings, the knife M and its plunger L will descend together until the plunger covers and holds the fruit in the cup. The plunger will then cease to descend, but the knife will continue its descent and divide the fruit into halves. At the same time the stone or pit will be forced from it, and the hook P will engage with the lip on the hinged section B. When the treadle is released the plunger and knife will be raised by the recoil of the spring Gr. At the same time the hook I? will tilt the section B and allow the pit to drop from the machine.

Having described my invention, what I claim, and desire to secure by Letters Patent, 18-

1. In a pitting-machine, the combination, with a plunger and knife, of the extension of the base A, and the hinged section B,having a fruit-holding cup, at, and the knives O 0, substantially in the manner described.

2. 1n apitting-machine, the combination of the spring tilting-hook on the plunger-bar with the lip on the hinged scctionB and the spring which acts to hold down this section, substantially as described.

3. In a fruit-pitting machine, the cupped sectional base B B, in combination with the double-beveled knife and the spring-actuated yielding plunger, constructed and adapted to operate substantiallyin the manner and for the purposes described.

4. The combination of the base A with its cupped portions B B, the standard with its spring-actuated shaft, the spur-Wheel on this shaft, the rack-bar, the spring-actuated plunger, and the dividing-knife, all constructed and adapted to operate substantially in the manner and for the purposes described.

5. In a fruit-pitting machine, the combination of a slitted spring-actuated plunger, the double-bex'eled knife, and the vertically-movable rod, to which said plunger and knife are applied, all constructed and adapted to operate substantially in the manner and for the purposes described.

In testimony that I claim the foregoing as my own I aftix my signature in presence ot-two witnesses.

CHARLES A. GURRAN.
