Hg.2lsaviewinperspectlveofaholderand occupylustpriorto position which carton is shifted ported upon this framework near each end of which is a sprocket wheel i'l over which trains an endless conveyor chain It carrying at spaced intervals fingers It which, on the upper run, extend upwardly to ride through the slot is. The 5 chain is continuously moved as by a driving connection 20 extending from a wheel 2| associated withoneotthesprocketstoawheel 22 thatis' scared to a motor M.

The two rails furnish a support on which the material to be operated upon is rested and slidingly advanced. Such material comprises a cellular holder H and a tubular carton C (see Fig.

2) having one or both ends open. The holder may be moulded from a pulp composition so as to be load-sustaining, all as described in my pending application filed August 10, 1935, under Serial No. 35,680. A holder filled with eggs or other commodities, when placed on the rails at the left end of the machine, as viewed in Figure 1, is adapted to receive engagement from one of the conveyor fingers and thereby be advanced toward the opposite end of the machine. During its travel the holder is led with the carton. and the resulting filler package P then 25 moves on between upstanding guides 23 to a discharge or take-off point.

The cartons which are desirably of rectangular form in cross section are initially collapsed into flat condition (see Figs. 6 and 7) for vertical stacking in a magazine which may comprise fourangle posts 25. The facing flanges It on the two posts adjacent the rails are cut away at the bottom and carry gauges which may be vertically adjusted to provide the requisite space for movement thereunder of the lowermost collapsed carton in the stack toward and upon the rails where I have provided an upstanding flange 21 which serves as a combined stop and guide. The successive feeding movement of collapsed cartons is effected by a plate 28 which is reciprocally mounted under the stack and connected for operation with an adjustable link 29 pivoted to .alever tl which is carried fast upon a shaft ll r kably mounted in bearings 32. A second lever 5 33 attached to the same shaft carries a roller 14 (see Fig. 3) adapted to track in a cam groove ll that is formed peripherally in a wheel it mounted on a shaft 3'! that is driven as by a chain II from the proximate sprocket wheel I1. 60 By some such mechanism as this the plate is reciproeated to displace from the stack the lowermost collapsed carton which is thereupon advanced to a position upon the rails against the stop ll.

The next operation upon the carton is to set it up. This is accomplished by an arm (or arms) 40 supported upon a shaft 4i which parallels the rails in proximity to the edge thereof which is 5 nearest the magazine. This arm is of a length which about corresponds with the vertical dimension of the erected carton and at its swinging or free end is turned toward the carton to provide a finger 42 which will closely overlie the proximate edge thereof. A rocking movement of slightly more than 90 is imparted to this arm. This is effected by a crank 43 which extends from the shaft 4| for pivotal connection with a link 44 whose lower end (see Fig. 4)

5 is joined to a lever 45 pivoted at 46 and provided with a roller 41 which tracks in a cam 48 formed in one end face of a wheel 48. By such a mechanism the arm 40, immediately after retreat of the feeding plate 28, is caused to rise up and engage the collapsed carton which is thereupon caused to "break" along preformed score lines defining its edges. In so doing, it is erected to the position shown in Fig. 7. In this operation the parts move through positions one of which is indicated by the dotted lines in Fig. 6. The angled free end of the arm effectively restrains any but a correct movement of the carton, and this is important because'of the resistance offered by the collapsed carton to bending at its four parallel edges two of which are initially related at 180 and the other two at 0 apart. When the carton is fully set up, the arm remains in vertical position as long as need be to cooperate. with the flange 21 in holding and 35 guiding the carton during the succeeding operations. After that the arm swings down again below the level of the feeding plate so as not to interfere with its next reciprocatory advance.

The holder II, when first advanced by the 0 conveyor chain, moves between a pair of walls 50 (see Fig. 1) into a guide which may be in the form of a shoe S having four walls about corresponding in transverse dimensions to those of the carton walls. These shoe walls, however,

5 are inclined inwardly very slightly and are resilient so as to be readily accommodated within an open end of the carton which, in the next operation, is shifted endwise so as to befitted over the shoe-guide which has a fixed mounting 50 upon the rails. The shoe-guide is, of course, slotted lengthwise of its bottom so as to allow the conveyor fingers to ride therethrough.

Each erected carton is, in turn, engaged at its end opposite the shoe-guide by a hand 5i which depends from a sleeve 52 by which it is pivotally supported. This sleeve is slidingly carried upon a rod 53 whose ends are secured in brackets 54 depending from a carriage 55 that is slidingly mounted on a pair of guide rods 56. To one end of the carriage is joined a link 51 in connection with one end of a lever 58 whose other end is fulcrumed at 59 (see Fig. 5), a yoke arm 60 extending from the lever to establish operative connection with a cam groove GI that is formed in an end face of a wheel 62 mounted on the shaft 31. The shape, of this cam is such that the carriage will be reciprocated only after the carton is erected whereby the latter may then be shifted endwise for fitting upon the shoe. This movement of the carriage stops when the carton and shoe are interfitted.

During advance of the carriage the sleeve is yieldingly supported by a light spring 63 which will compress only after the carton is fitted upon the shoe-guide. The hand which acts to advance the carton is sustained in a vertical depending position as by an arcuate finger 54 pro- Jecting therefrom to carry on its end a roller 55 which engages with the under wall of the 5 sleeve wherein is an arcuate slot 66 whose opening is normally offset with relation to the finger. As long as there is no countershifting force exerted upon the carton this finger will continue to abut the sleeve and be braced thereby; but 10 when a reverse movement of the carton commences, the sleeve will recede until the finger is positioned opposite the slot 65. At this point the finger will enter the slot and withdraw its bracing of the hand which will thereupon swing is upwardly and out of the way, as shown in Fig. 9. With the carton fitted upon the shoe-guide, a holder H which is advanced by one of the conveyor fingers will pass through the guide and enter the carton. The inclined resilient walls 20 of the shoe act to guide the holder accurately in reaching this position. During this operation the hand 5| remains engaged with the end of the, carton to act as a stop so that the carton will remain stationary. When the holder has been 25 completely received within the carton, the conveyor finger then engages the latter with the result that the sleeve is retracted to the point where its hand is freed to swing back and out of the way. The carton with a holder assembled 30 therewithin may thereafter continue to advance without restraint. This movement proceeds as indicated in Fig. 1 toward the delivery or takeoff end of the machine where the filler package, complete with eggs, is ready to be packed for 35 storage. shipping or other purposes.

The present machine is advantageous because of its extreme simplicity and the certainty and speed of its operation. It is characterized by (1) means for advancing a collapsed carton; 40 (2) means for setting-up the carton; (3) means for shifting the carton into interfitting relation with a guide; and (4) means for advancing (a) a holder through the guide into assembled relation with the carton and (b) thereafter the filler package complete. In the performance of these operations the erected carton is sustained between appropriate walls and is advanced to interfitting relation with the shoe-guide by means which thereupon serves as a yieldable stop to r assist the holder in entering the carton. All such mechanisms which cooperate to perform these operations are driven by mechanism which is simple and timed in accordance with the sequence of the successive operations.

It will be noted that the carton is advanced initially in a state of collapse by a transverse movement, it is then set up in the path of movement of the holder, it next receives a further movement, this time longitudinally of itself, relative to a guide to which it is then fitted, following this it receives the holder which passes through the guide to enter the carton, and finally it again moves endwise of itself, but this time in a direction reverse to that in which it was previously shifted. The path of the holder movement is simple, whereas that of the carton is compound. The means for finally moving the carton with the holder assembled therewith is the same means which advances the holder into 70 the carton. The path of carton movement which is compound coincides in part with the single path through which the holder itself is moved. By this relationship of movements I am enabled to expedite the several operations, including that 75 of assembly of the holder within the carton, all in a satisfactory and uniform manner.

I claim:
