Gaddini, Winters, Calif. Application April 14, 1945, Serial No. 588,336, 14 Claims. (Cl. 146-23) ~ 2 1 The present invention relates in general to the art of automatic fruit machinery, and especially machinery of such character adapted to accom plish mechanical halving and pitting of stone fruit, such as peaches andv apricots. This invention represents a modi?cation of the Fruit holder shown inv co-pending application, Serial No. 588,335 ?led April 14, 1945. One object of this invention is to provide an individual fruit holder of novel construction adapted for use, in an automatic fruit. machine, to firmly hold the fruit in a predetermined posi tion for sequential operations thereon, which re a holding unit for fruit which will be effective for the purpose for which it is designed. These objects are accomplished by means of such structure and relative arrangement of parts as will fully appear by a. perusal of the follow ing speci?cation and claims. In the drawings similar characters of reference indicate corresponding parts in the several views: Figure 1 is a longitudinal. sectional elevation of the fruit holder with the-fruit supported there by and the bottom cut made by the upstanding supporting knives. Figure 2 is a cross section of the holder with. sult in halving and p‘itting of. the fruit; there the fruit therein, illustrating the side cutting op being a number. of said holders mounted on a 15 eration. conveyor which moves the same intermittently and step by step through separate stations at which different operations are performed on said fruit. An automatic fruit machine of the above type is illustrated in copending application, Se Figure 3 is a longitudinal sectional elevation of the holder after the fruit has been cut both bottom and sides; the fruit halves being spread apart about the uncut top portion as a- hinge and pre 20 paratory to ejection ofthe pit. rial No. 533,548, ?led May 1, 1944; the essence Figure 4 is a fragmentary plan view of the fruit of the instant invention residing in the particu holder. lar form and operation of the fruit holders. Referring now more particularly to the char Another object of the invention is to provide a acters of reference on. the drawings, the fruit fruit holder, for the purpose described, which is holder, of which a number are used ineach auto— arranged to be actuated at a. predetermined sta matic fruit halving and pitting machine in. spaced tion, after certain bottom and side cutting oper relation on an endless conveyor, comprises the following: ations on the fruit, to cause separation of the fruit halves at the bottom and about the uncut The numeral 1 indicates a rectangular frame, top portion of said fruit as a hinge, whereby to 30 said frame being open top and bottom on oppo maintain the fruit in proper position for engage site sides and centrally of its ends theframe l ment and ejection of the pit by a downwardly includes depending attachment ears 2 which con moving pit ejection rod at said station.

The rollers II have axially outwardly project ing roller extensions l3 thereon for the purpose which hereinafter appears. Each side 4 exteriorly thereof and between the corresponding cam slots II} is ?tted with a spool I4 on which an opposed leg, coil spring I5 is being spaced apart a distance substantially equal to the width of the pit 25. The knives 28 are mounted by parallel links 29 on a cross head 30 for parallel separating movement, and are nor mally urged towards each other by a connecting tension spring 3I. The cross head 38 is opera tively suspended in the machine by a vertical member 32 adapted to be reciprocated in timed disposed, the legs I6 extending from the spool in opposite directions and engaging with enlarged 10 relation to movement of the holder 'to the fruit side cutting station. The knives 28 are sharpened pulley-like guides H on the rollers I I'between the along adjacent edges, and are relatively pointed latter and the roller extensions I3. The action at their lower ends and sharpened on both edges of the spring legs I6 is to cause the rollers II to of said points, normally move toward and engagein adjacent After the holder comes to rest at the side cut ends of the cam slots I0, whereby the base plates 15 ting station, the side cutting unit 21. descends 6 are then in the horizontal and adjacent posi and knives 28 cut the fruit 25 on both sides of the tion shown in Fig. 1. pit; the cuts running inwardly directly to the pit, Adjacent end portions of the cam slots ID are and. extending from top to bottom of the fruit. straight and horizontal, and the rollers I I engage therein with an easy running but relatively close 20 In order to assure that the descending knives 28 clear, the outer edges of the upstanding knives ?t. The opposite or outer end portions of the cam I8, upwardly and inwardly inclined cam edges 33 slots III incline upwardly and are progressively are formed on adjacent edges of the knives 28 increased in height toward the outer end.

With continued descent A pair of ?at upstanding knives I8 are normal of the side cutting unit the cam pins 34 riding ly disposed transversely in edge-to-edge but spaced relation centrally between adjacent edges 30 against the cam edges 33 cause the knives 28 to separate slightly and to an extent such that said of the base plates 6; the knives I8 including op knives pass closely along the outer edges of the positely projecting, normally horizontal bottom knives I8. It will be noted that with the bottom ?anges I9. The bottom ?anges I9 intersect the cut made by the knives i 8 and the side cuts made corresponding base plates and are secured there to by bolts 28. The upper edges of the knives 35 by the knives 28, the peach halves 36 are cleanly cut apart about the sides and bottom. The only I9 are sharpened, as at 2!, and these sharpened remaining uncut portion is the top portion above edges converge inwardly and downwardly, the the pit.

Each base plate 6 is ?tted, centrally of its ends 45 roller extensions I3 on opposite sides of the frame I. With such descent of the cams the roller and intermediate its side edges, with a spring extensions I3 will move apart equally in oppo urged, upstanding fruit engaging ?nger 22 of sub site directions and the rollers It and I2 move stantial width and curved outwardly at the top along the cam slots It} to effect a corresponding for ease of fruit engagement between said ?ngers. The ?ngers 22 are pivotally mounted between 50 movement of the base plates 5.

The fruit halves are thus shape de?ned by the cutting edges 2| of the separated at the bottom and about the top hinge knives I8 permit the bottom out to be made to a point Very close to the pit. As so impaled on the knives I8 the fruit is frictionally engaged on opposite sides by the spring urged ?ngers 22. With the fruit so positioned in the holder the latter moves to the next station, where the fruit is acted upon by a downwardly moving side cut without any tearing or rupturing of the ?esh ting unit, indicated generally at 21, and which of the fruit halves; said halves being ?rmly and frictionally engaged between corresponding knives I 8 and spring-urged ?ngers 22.
