s claims.' (ci. iis-49p i This invention relates to machines for stacking open-mouth boxes, such as vcartons or trays, having collapsible sides VIVand-ends, and it has for its l object to provide a simple 'and efficient construction and organization-of mechanism whereby such exclusively, designed V'for use in connection with or fas an attachment to machines for Vmaking shal-` low collapsible cartons whereby the lsaid cartons asrap'idly las they are ldischarged from the ma- A chine are intercepted 'and Vcompact-1y assembled.

The invention, broadly considered, comprises time combination With means `for 'supplying collapsible boxes, of simple,` Jdurable and lefficient means for natten'ing the boxes and 'arranging speciiica'lly, vthe invention comprises the combination 'with a carrier for 'supporting a 4successiono'f fcollapsible boxes, bottoms downward,

and feeding them ksuccessively to a point of discharge, 'and "a" vertically-reciprocating plunger for discharging the boxes successively from the carrier, Yof a box receiverA under the path of the phrnger, means for `temporarily supporting each succeeding box at the mouth 'of the receiver, and means for folding 'the collapsible end Walls of Vthe box ina iriannerto bend the side walls outwardiy in the same plane as the bottom of tire box, `and at the same time depressing the flattened box into the receiver.

The invention also comprises various features of construction and `combinations of parts which will be hereinafter described; the sc'op'e of the invention Vbeing expressed in the appended claims;

-5 is 'a perspective View of a collapsible Vbox or carton.

vFig. 6 is a similar view 'of said box Aor carton as collapsed 'or flattened. Y Y 1' v Referring tothe drawings, irdesig-nates se eral of the open formel-links of the endless chain of 'a welbknown type of 'box-making 'machine, which links are intermittently impelled in the usual manner to t-he path -of a verticallyreciprocating ejector 11,4v Ywhereby A'in :each dwell of the chain a collapsible box (B) is 'discharged from A`one of the'links through an opening 1'2 in a-table `13 which is supportcdby Va 'standard 14 cn then-ame structure.

:The form Aof box herein illustrated comprises a 7' bottom a, end walls b and side walls c, the latter having therein adjacent the ends ldiagonal scores `or creases d which enable the box to be collapsed 4or fiattened by the application of in- 75l ward pressure to the respective end walls.

The form of Vejector illustrated is similar to that described in Letters Pat-ent of the United States No; 1,287,088 dated December 110, 1918, that is to say, it comprises a 'yielding lframe ofy inverted V-forni supported by a vertically-reciprocative cross-head 15 which is mounted on vertical `guide posts 16 'on the table. This cross-head is connected by means -of a-link 17 'to vone arm of a rocklever A18 which is fulcrumed on a standard 19 on the supporting frame. The 'other arm of the'lever is connected by means of a link 20 with one -arm of a lower rock-lever 21 which is also fulcrurned on the standard 19; the other arm of the lever 21 having a roll '22 operatively fitted in the run of a suitably-disposed face cam 23. This cam is fast on a drive shaft i231 having its bearings in suitable standards, including the standard 14 on the main frame, Vwhereby during the -operationof said shaft the cam in its rotation cheats, through the described Ylever and link connections, the timely reciprocation of the Vejector' in respect to each lsucceeding link of the box chai-n. v

As` each box is discharged through the opening 142 -of the table 13 the `box is temporarily supported at the mouth of a guide chutev2`5 depending from the table, which box is Vcollapsed vor iiattened and 'then entered in the chute, as will presently appear. This chute is `of appropriate internal for-in and dimensions for the reception and guidance therein ofeach succeeding flattened box,so that when the articles are discharged `from ing element for the iiattenecl boxes. 11,0

At the top of the chute 25 are ngers 26 which are movable into and from the paths of the end portions of each succeeding box discharged from the chain 10, the walls of the chute having suitable openings 27 for the passage of the fingers. These fingers when in inward position intercept and rsupport the box as it is discharged by the plunger 11, and when in outward position they permit the descent of the nattened box in the chute. In the present instance the fingers are formed on the upper ends of upstanding arms 28 having at their lower ends sleeves 29which are fulcrumed on shafts 30 fixed to brackets 31 on the bed 32 of the machine. Fast on the sleeves 29 are upstanding arms 33 having at their upper ends rolls 34 which are normally maintained in operative contact with a cam 35 by means of suitably-disposed springs 36. yThis cam is fast on a shaft 37 which has its bearing in the standard 14 and is driven from the main shaft 24 throughv meshing gear wheels 38 on the respective shafts. The contour of the cam 35 is such that the arms 33 and their companion arms 28 are simultaneously actuated to eiect the inward and outward movement of the fingers 26 in timed relation to the operation of the box ejector.

Two oppositely-disposed folders are reciprocative in longitudinal paths intersecting the vertical planes of the respective end walls of the box overlying the chute, whereby such ends and the creased corners of the `sides of the box are pressed down in ar manner to collapse or atten the box, that is,.the ends are folded inwardly and downwardly and the sides are bent outwardly n the same plane as the bottom of. the box. (See Fig. 6). In the present instance each of the folders comprises an elongated body plate .39Y

having upstanding perforated ears 40 which are slidably fitted on a guiderod 41 projecting from the table 13, and having also spaced depending ironing members 42 of substantial length which are curved or beveled at their nose portions/43 so as to bear smoothly against and irondown the opposing end wall of thebox. The folders are connected ,by means of links 44 to theupper ends of upstanding arms 45 having at their lower ends sleeves 46 which are fulcrumed on Yshafts 47 fixed to brackets 48 on the bed of the machine. Fast on the sleeves 46 are upstanding arms 480, the upperends of which are connected by links 49 with upstanding arms 50 pivotally supported on the respective shafts30. The arms 50 are equipped with rolls 51 which are normally maintained in operativecontact with a cam 52v fast on-the shaft 37 by means of suitably-disposed springs` 53, the contour of the cam 52 being Vsuch that the arms 50 andtheir associated arms 45, 480 are simultaneously actuated to effect rthe requisite inward and outward movements of the folders in timed relation to the operations ofthe fingersk 26 and the box ejector 11. Y

In the construction illustrated the ratio of the gearing between the shafts 24 and 37 is such that the shaft 37. whichcarries the cams 35 and 52 makes one rotation during two rotations of the shaft 24 which carries the cam 23; the contour of the latter cam isk such that the ejector is lowered and raised during one-half rotation of the shaft 24 but is at restduring the remainder of the rotation, and the relative contours of the two cams 35, 52 are such that in each rotation of the shaft 37, while the ejector is atk rest in raised position, the arms for actuating the fingers 26 and folders 42, respectively, are reciprocated inopposite directions toeach other. j

. 42 are moved inward, the lower acting surfaces lof such folders thus pressing the opposing end In the relative positions of the parts shown in Fig. 2 the fingers 26 are in inward position, a box (B) is seated on the fingers, the ejector 11 is up and the folders 42 are outward. In a quarter rotation of the shaft 37 and its cams 35 and 52 the parts are caused to assume the relativey positions shown in Fig.l3, that isvto say, the fingers 26 are gradually moved outward away from the ends of the box, and coincidentally the folders walls b of the box inward and downward and the scored or creased side walls c outward and downward and at the same time forcing the flattened box down in the mouth of the chute, In the next quarter turn of the shaft 37 the folders v42 are moved outward, the fingers26 are moved inward upon the ends of the previously flattened box, and the ejector is moved downward and upward, another box being positioned on the fingers by the descending ejector as seen in Fig. 2. In the next succeeding two quarter rotations of the shaft 37 the operations just described are repeated, and so on the succeeding boxes are discharged from the box making machine, flattened, and entered in the chute. The assembled boxes progress to the bottom or discharge end of the chute from which predetermined quantities can be removed for packing or other purpose.

It is to be understood that my invention is not limited to thestructural features herein illustrated, as the mechanism may be variously modinedv within the principle of the invention and the scope of the appended claims.
