OF LOCKLAND, OHIO, A CORPORATION. OF OHIO I MACHINE FOR FORMING CARTOLl'S Application filed September 13, 1929. Serial No. 392,451.

7 objects of my invention. These objects will be pointed out hereinafter or will be apparent to one skilled in the art upon reading these specifications. Reference is made to the ac-' companying drawings. Figure 1 is an isometric view of a simple form of my machine.

Figure 2 is a longitudinal section of a platform carton of a type which I shall use as exemplary in explaining the construction and use of my machine.

Figure 3 is a representation of the blank from which the carton of Figure 2 is to be set up.

- Figure 4 is a sectional view through my machine showing the platform-folding members in upraised position.

Figure 5 is a side elevation of my machine with a portion cut away, showing the blank inserted in the machine before the operation of the platform folding members.

The several drawings are semi-diagram 1 matic in parts, and all but the essential por-' tions thereof have been omitted. Thus, I

have not shown a machine equipped with feeds, plungers and the like, for the complete automatic setting upof cartons. The type of machine which I show is one adapted for the facilitating of a rapid semi manual operation of setting up one type of carton. This type, however, embodies means for setting up the main portion or body of the carton and the folding ofthe recessed panels into position. These means are the subject matter of this invention.

My machme, embodying the said means, is

suitable for the setting up of many types of platformcartons, and is not restricted to types in which the platforms are an integral part of the carton blank. In describing the construction and operation of my machine in connection with. the carton shown in blank forminFigure 3, I desire it to be understood that my machine is not limited thereto, but. is equally adapted to the setting up of gluetypes of cartons, such as, for example, but

7 without limitation, the carton of my copending application Serial No. 394,444 filed Sept.

23, 1929., and other types.

The carton of Figure 3, forms the subject matter of my copcnding application Serial No. 373,123, filed June 24, 1929. The blank comprises a bottom member 1, side members 2- and 3, and a top member 4 provided with a tuck end flap 5. These members are articulated together, score lines being indicated by dotted lines. To the side member 3 are articulated, by means of platform supporting flaps 8 and 9, platforms 6 and 7. These platforms are provided with side flaps 10 and end flaps 11 and 12, all of a width proportioned to the recessing of the platforms as determined by members 8 and 9. The side member 2 has at' its ends two flaps .13 and 14, provided centrally of their outer sides with comparatively narrow locking tongues 15. The flaps 13 and 14, when the box is set up, are designed'to fold over the flaps 11 and 12. In the line of score whereby flaps 11 and 12' are articulated to the platforms 7 and 6, occur slits or cutlines 16 to receive the locking tongues 16. The assembly of the carton will be clear from the section, Figure 2. When the locking flaps are in place the carton'is held in fully assembled form even when the lid is open, which is not the case with any other unpasted platform I carton formed of a single blank. The platforms may have appropriate holes 17 and 18,

where desirable, to hold such a fragile object as an incandescent lamp, the hole 17 holding the bulb end thereof while the hole 18 engages the screw base, permitting the testing of the lamp without its removal from the carton.

essential in holding it in set up relationship, they are of assistance to that end inasmuch as they resist any movement of the platforms inwardly such as would permit the disengagement of the locking tongues from the slots While the contents of such a carton are not 9 rear side member of the machine, and the top ship .16. The carton is closed after filling like any other tuck end carton, the tuck end flap 5 seatmeans for performing the initial forming op-' erations, comprising the setting upof the body portion of the carton, and the correct positionin of the recessed platforms. In this embo iment of my invention, a suitable base 20 is mounted at a convenient height for the operator as by being mounted upon-a table, or upon the legs 21. Two side members are mounted in, such a way as to extend upwardly from the .base so as to hold the sides of the carton body in the desired rectangular relationship. The side members are conveniently formed of pieces of sheet metal 22, and may be mounted upon elongated blocks 23 which are affixed to the base. The members 22 are rolled or turned over at their upper edges 24 to facilitate the initial setting up operation. The carton blank of Figure 3 is placed above the two side members of the machine with the side member 3 therebetween.

The blank is then depressed forcibly until the side member 3 of the carton liesalong the base, the bottom member 1 lies along the member 4 liesalong the front side member of the machine. These several members of the carton blank will then lie at right angles to each other; but the side member 2 will not be bent over, but will extend upwardly in the same plane as the bottom member 1. The blanks may of course be-fed into the machine automatically, and the' depressing of the blank also accomplished automatically as by a plunger. It will be possible also in a modification of the structure to hinge the side members'22, swing them downward,.position the blank, place a form above it, then bring up the side members, bending the blank to shape, and finally to withdraw the form. These modifications and others do not change the spirit of scope of the invention of this application. 'In the form shown, the machine side members 22 are fixed in position with reference to the base, and a blank is placed above them by hand, and depressed between them by hand. Machinesare in common use which will take a carton blank, bend it to the shape of a rectangular carton and glue the several parts. There has been to my knowledge, however, no mechanism hitherto devised to set up into a carton body an articulated integral platform in proper recessed relation- I accomplish the setting up of 'the platforms by providing members 26 and 27, suitably pivoted with reference to the base, and adapted to swing from the horizontal to the vertical. In their horizontal position their inner or opposed edges, as shown in Figure 5, are separated by a distance only slightly greater than the length of thecarton. Their horizontal upper surfaces are separated from the base by a distance equivalent to the width of the platform supporting flaps 8 and 9. The result of depressing a blank between the side members 22 is to cause these flaps to be bent at right angles to the blank member 3, and to lie along the opposed sides of the members 26 and 27. I

These members are conveniently in the form of blocks, pivoted on shafts 28 and 29 which may extend through the members 23, and which may be equipped with wheels 30 to which are attached the ends of a bifurcated chain 31. This chain may run to a foot treadle 32 as a convenient means of power actuation. The wheels are fast on the shafts, and the shafts are fast in the blocks 26 and 27. The working of the foot treadle by an operator will result in the swinging of the blocks from horizontal to vertical position.

When the blocks 26 and 27 are in vertical positionytheir inner opposed sides correctly position the platforms recessed within the carton body, and their lower edges are separated from the base a distance such as will give proper clearance to the blank member 3 and the platform supporting flaps 8 and 9, which are superposed thereon. This is clearly shown in Figure 4. The mechanical movement of the blocks successfully positions the platforms, which is a diflicult operation because a horizontal thrust would tear or loose.

The side edges of the members 22 are also turned over or rolledas at 25 to facilitate the bending over of the flaps 10 on the plat-- forms as they are swung into position; and the rolled portions have fingers 25a which serve the combined purpose of guiding the platforms and flaps into the carton body, and of holding them there when the blocks 26 and 27- return to horizontal position under the influence of springs 35 when the treadle is released. The blocks are hollowed out as at 33 and 34 to accommodate the ends of an incandescent lamp bulb 19 which project through the holes 17 and 18 in. the platform.

In using my machine, an operator takes a blank in one hand and depresses it between the upright members 22 until it occupies the positionshown in Figure 5. Then with the other hand she places a lamp within the carton body, as shown in Figure 4. Operating the foot'treadle she swingsthe platforms into position by means of the blocks 26 and on top of them, and then the side member 2 over all. Finally she turns the locking flaps 13 and 1 beneath the platforms 11 and 12 and inserts the tongues 15 into the slits l6.

' dicated, the platform positioning blocks 26 and 27 have swung down out of the way. The completely set up, filled and closed carton is'thereupon removed from the machine.

These operations 'may be followed and repeated with great rapidity.

As hereinabove indicated the embodiment of my machine which I have described is a simple form, but embodies my invention. It may be made automatic in operation and may be equipped with automatic feeding and de livery devices. It is capable of modification without departing from the spirit of my invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is a 1.
