The elevator I3 carries the globular objects to the position indicated at 1'6 where they are permitted to roll from the elevator l3 into the entrance end I! of the apparatus of the present invention. The endless belt l4 may be lapped around a roller 18 suitably supported by a shaft l9 to which may also be keyed a spur gear 20 adapted for use in the drive of mechanism of the present invention.

.As shown in Figs. .1 and 2 the novel feeding apparatus may comprise a wide chute 2| adapted to receive at its entrance end IT a haphazard supply of the globular objects or oranges. If this chute is to be employed in the separate feeding of a plurality of rows of receiving :cups, such as three rows which may be staggered .desired'as proposed in the above identified Walker patent, the objects must be taken from the common haphazard supply and arranged in three single files,

or as many files as there are rows of receiving cups in the moving receiver, without undesired jamming. For this purpose the inclined chute 20 may be provided with a pair of dividing walls 22 and 23 which, together with side walls 24, 24 of the chute 2|,provide three separate ways down each of which the objects are to tumble in single file.

Feeding into the 'three separate ways may be accomplished by foreshortening the entrance ends of the ways. Preferably such foreshortening is of a distance approximately equal to, or somewhat greater than, the average diameter of the objects so that feeding to all three ways in auniform and eflicient manner will 'be assured. This is indicated in both Figs, 1 and 2 wherein the dividing wall 23 is shown to be foreshortened about the diameter of one ofthe objects A with respect to the entrance end of the dividing wall 22.

In accordance with the development of the present invention it 'was unexpectedly found that jamming, or ineificient feeding or arrangement of the objects .into'the respective single files, could be effectively avoided at all times by'the employment at the'bottom of the ways in the vicinity of their entrance ends of object agitating means such as upwardly movable means to engage the objects and agitate them, thereby assuring that they will fill up the longer way, spill overand fill up th next longest way, and spill 'over again to fill up the successively shortened ways in an orderly fashion. In accordance with the preferred embodiment of the present invention this is preferably accomplished by a link belt structure. 215, the upper stretch of which may extend substantially completely across .the chute 21, a sec.- tion of the bottom 26 thereof being preferably removed as is .indicated ,inEigs. 1 and 2, and with the upper stretch of the .link .belt serving as the bottom of the ways at least in the vicinityof their entrance ends.

The link belt structure may be rotatably .supported :on a pair of rolls .2! and 28 with the roll 21 fixed to a shaft 29 :to which may be keyed a spur gear 30 :meshed with the spur zgear 2.0 to

be driven from the latter. "The roll 28 may also be fixed upon a rotatable shaft 23] to'which may be keyed :a pulley '32 about which a belt l33 may be lapped for the drive of other mechanism, as hereinafter indicated. Of course it will be *understood that the belt structure need not hecessa-rily be a link belt structure, but the latter :is preferred due to the uneven surfaces and .projections provided thereby which assure a better grip upon the surfaces of the globular objects to assure the efi'ective agitation thereof.

The three ways, depicted by way of example, or resultant chutes provided by the side walls 24, 24 and dividing walls 22 and 23 may feed to any desired receiving means, but preferably are associated with the retard roller apparatus of the above identified Walker patent for the reasons therein indicated. Obviously the retard roller means may comprise three separate chutes each of which is aligned with one of the chutes provided by the above desirably subdivided chute 2 I. However, for the purpose of simplicity the three ways of the chute 2| may be continued to provide the three ways of the retard roller means as is proposed in Figs. .1 and 2.

In such case the two side walls 24, 24 may support in the vicinity of their lower ends a rotatable shaft 34 to which is keyed apulley 35 to be driven by the belt 33. The lower end 36 of the chute 2| may thus constitute a delivering end terminating adjacent the cylindrical receiver 10 means may be a single roll structure suitably grooved in the vicinity of each of the three ways or it may comprise a plurality of 'hyperboloid .elements 38-38, one for each of the ways as is indicated in Fig. 2. When the rollers 3838 are so shaped they have the advantage. of tending to center the objects regardless of the shape of the ways so that the objects fall into the middle of the cups l2--l'2 "of the receiver, l0; there to be prop! erly located and securely seated. These retard rollers are preferably made of hardor unyielding material, but may be made of or-surfaced with somewhat resilient material such as rubber or the like. These rollers are spaced from the bottoms of their respective chutes a distance sufiicient to 0 permit. the fed objects to move by gravity past them to the receiver, and the distance between any portion of the surface of the cups 1-2-12 and an opposed portion of the surface of the rollers 38-38 is preferably slightly morev than the distance between that.,portion of .a cup surface andthe opposed portion of the protruding surface .of any object to be located thereinso that the .objects will pass freely beneath the rollers when the objects are properly seated. in the receiving ;cups' thereby permitting them to he .carriedaway in more detail in the above identified Walker patent. The chute 2.] is inclined, as shown inli'ig. 1, so

that the globular objects will tumble down-it and its respective ways due to the force of gravity, The inclination of the chute f2] may beat an angle of about fifteen toforty-flve degrees, and the entrance portion thereof should be of'suflicient length to obtain a free movement of the globular-objects before they ar diverted into the separatepaths of th successive ways provided by the foreshortened dividing walls 22 and 23.

Although thestructures shown in Figs. 1 and .2 are preferred, it is obvious that other agitating means maybe -provided,;such as a'pair of roughened rolls 39.39,, -.one of-which has the peripher thereof rotated in ;a. .slot 40 in the @bottom 26 of the chute somewhat medially of the way .70 provided by the side wall 24 and dividing wall .22 in the yicinity of the entranceend thereof; The otherroll 39 similarl has-its periphery rotated inaslot the bottom .of theway provided by the dividing walls and 23 alsoin the vicinity of by movement of the receiver, all as is explained.

the entrance end thereof. When the rolls 39.3.9 7

are rotated 'in'a suitable direction, 'such-asindicated b'y the' 'arrow in Fig:3,"it-'wil1 be seen' thafi eachfprovi'des an' upwardly movable means atth'e' 1 agitatethem so as to draw 'theffruit away from the entrance ends should there be any "tendency for the same tojam. at that locationas tempt to enter the difierentways.

A similar end may be obtained" by? 'pr o'viding the upwardly n'iovii'lg' means at the 'bo'ttdrrf qr the waysin the rvicinityfof their entrance-"ends such as by the provision Of an agitating plate-ji aspropos'edin'l igge. This plate'4l may "'e locatedina slot 42 in the "bottom of the chute structure 2 I1 in'the vicinity of the entrance endsof 'the'successiv'ely foreshort'ened' ways; and pre'f erably extends substantially entirelyacrosschut 2|'.=. "In' order to avoid any tendency for a down wardly zmoving surface to increase any jamming tendency, provision mayibe made "for assuring that'the plate 4| is held in the'plane of the bot 7 tom 26 of the chute 2| only as it i's-slid upwardly from itslowermost position to its uppermost po sitionr It may then be retracted out of thesl'ot 42 soias toavoidengagement with-thesurfa'ces of the objects during return travel downwardly to its initial position. For this purpose *the'plate 4 =-may,,.be suitably supported upon" one or more arms 43 and; one or'more' arms "44." The arm or arms 43 'may carry a stu'dior shaft andthe' ar'm" or arms 44 may carry: a:similar-studor' shaft 46. The studs or 's'hafts 45 and 46 are slidably supported upon asurface 41 sprovided'by a-ne1on"-' I gated slot548 inan enlarged head 49 0f a member 50 reciprocatively supported in any suitable man nor s'uchias by means 5 I. :This reciprocating and s a pin :52 disposedin a ng structure may be i u ns; I

A stopiama'y rocation of'the plate 4| may be obtained in any suitable manner such as by an arm 59 having a slot 60 receiving the pin or shaft 46, and with the arm 59 pivoted to a reciprocable 'arm 6|. The bellcrank lever and the arm 59 maybe as upon a common shaft 62.

In operation of the embodiment shown by way of example in Figs. 1 and 2 the. elevator or slat conveyor |3 carries oranges up to the position l6 and dumps them into the entrance end ll of the chute 2|. This is done in a haphazard manner without any attempt to segregate; align, or prearrange the oranges. The latter, then start rolling down the inclined chute 2| over the bottom surface, provided by the upwardly moving top They then continue to tumble down the surface of the moving link belt a sufficient distance to obtain a free movement, after which they approach the entrance ends of the three ways provided by the side flanges 24, 24 and the foreshortened dividing walls 22 and 23.
