BY Q/lhmZ/ZM w I Patented May 22, 1951 UNITED STATES OFFICE MECHANISM AND METHOD FOR MAKING BOXES WITH ATTACHED HANDLES AND THE LIKE My invention relates, in the specific embodiment hereinafter described, to a one piece type of box, which can be shipped fiat or in knocked down form, and can be erected readily for packing by the user. It is an object of my invention to produce a box of the character noted which will provide both a bottom and lid, having front and side Walls, said walls being joined at corners where they meet, the box being provided with handles to permit it to be readily and easily carried.

There have been attempts to solve the problem of providing a handle box for use by department stores, womens specialty shops, etc. Many such attempts in the past involved the use of separate handles in one form or another, which had to be attached by the sales clerk after the garment was packed. This not only caused a considerable loss of time, but involved the problems of handling separate boxes and handles.

Another approach to this problem in the past practice has been through the use of various cutouts or cutaway portions from the box itself, to form a handle. proach is that such cutouts both disfigure the box, spoiling its appearance, and lessen the structural strength of the box. Another defect is that the boxes known in the trade customarily as suit or clothing boxes are made normally from boxboard containing a high percentage of waste paper, which lacks any considerable degree of tearing strength. Accordingly, such cutout handles, being no stronger than the board of the box itself, tear very readily and have proved decidedly troublesome.

By my invention as herein described these difficulties are overcome. My box is provided with handles formed of separate pieces of stock, so that there is no disfigurement or loss of strength or cutting away of the box itself. Furthermore, since my handles are made of separate pieces of stock, the stock used in the handles can be of solid kraft board or other board of superior quality and strength, if desired, thus providing tear resistance. This is achieved economically, since the higher grade stock is used for the handle portion alone, the remainder of the box being made from the ordinary grades of box- One of the defect of this apboard customarily used by the trade. Again, the

2 is a sturdy and dependable grip on the box, providing a safe carrier.

By my invention as herein described I not only provide boxes with handles attached having the features previously enumerated, in a high speed and fully mechanized operation; but I also provide methods and mechanisms whereby this is accomplished as a part of a continuous series of operations in which the box blank itself is folded and glued, producing thereby a handle-attached box in complete form in a single and continuous operation, with insignificant additional manufacturing or labor cost as compared to the production of ordinary boxes without handles.

My invention can be used in connection with the machines described in my Patent No. 2,149,- 111 issued February 28, 1939, and in conjunction with the mechanism and methods described in my Patents, No. 1,926,364 issued September 12, 1933, and No. 1,974,408 issued September 25, 1934.

It is also particularly adapted for use with the.

method and mechanism described in my Patent No. 2,145,682 issued January 31, 1939, having to do with a reinforced, one piece box.

While I shall describe my invention in the exemplary embodiments aforesaid, it will be evident upon reading these specifications that the principles of my invention are applicable to the problems of attaching handles or other fixtures to other types of boxes.

The main objects of my invention will be apparent from the foregoing; and these, as well as more specific objects which will be set forth hereinafter or will be understood by the skilled worker in the art upon reading these specifications, I accomplish by those mechanisms and methods, and in those structures of which I shall now describe the exemplary embodiments.

Figure 11 is a fragmentary sectional view showing the reciprocating pressure members that press the handles into contact with the box blanks.

Figure 12 is a fragmentary plan view of the platen on which the handle rests preparatory to the application of the handle to the box blank.

Figure 1a. shows a blank for a preferred form of box, prior to the folding and gluing of the blank and prior to the application of the handles. There is a main bottom panel i, having side panels 2, 2, a wall 3-, which for convenience will be called a front wall, and a wall 4, which for convenience will be called a back wall. Articulated to this back wall is the main body panel 5 of the lid, said lid having side walls 5, 6 and a lid front wall 'I.

Extending laterally from the front wall panel of the box bottom portion are the corner sustaining flaps 8, 8 and like corner sustaining flaps 9, 9 extend laterally from the lid front wall panel. The side panels 2, 2 have diagonally scored portions 2a, and the side panels i5, 5 have have like portions 6a, 6a.

Between the side Wall panels of the lid and bottom portions of the blank are intermediate corner connecting sections havin diagonal lines of fold therein. They may be described as having a median portion It, with triangular sections ii, I! and l2, l2 articulated by diagonal fold lines to the median portion and to the respective side walls by a fold line normal to their length.

The successive stages of folding as illustrated in la, Eb, Ic, id, and I are preferably as car ried out by my patents previously referred to in which flaps 2a, and 6a are first turned under as 4 shown in Fig. 1b, then the entire side walls 2 and 5 with the connecting portions I ll, il, i2

are turned over inwardly, as well as flaps 3 and a as shown in Fig. 1c. Thereupon there occurs a change of direction of motion of the blank as shown in Fig. 1d, and during this second motion adhesive Will be applied to the blank. The adhesive for forming the knocked down box structure as such may be applied to the flaps 8 and 9 as shown by stippling in Fig. 1d; or it could be applied to the turned over triangular portions 2a and 6a.

In my Patent No. 2,145,682 I have taught a mechanism for applying a reinforcement to the back wall t of the blank at the next illustrated stage, and where this is done, adhesive may also be applied as at la to the back Wall 4' at the stage id.

In the stage illustrated in Fig. 1e the rein for'cement 13 has been applied to the back wall as by mechanisms shown in Figure 5a and as taught in my said patent. In the next stage, the walls 3 and 7 together with their folded flaps 8 and 9 are turned inwardly as shown in Fig. if to complete the knocked down box as such.

However, in my present invention at the stage shown in Fig. 1e, separate die-cut handles [4, Id are fastened at the position indicated in that figure to both the bottom Wall I and lid wall 5 as by mechanisms shown, for example, in Figure 6 or Figure 11, and as shown in the next stage, Fig. 1f, the parts of these handles extending beyond these bottom and lid walls, that is, the handle portions underlying the end Walls 3 and l are folded over with the end walls. Pressure is subsequently applied to secure adhesion between the diagonally scored portions 2a and the corner sustaining flaps 8-8 as well as to augment the adhesion between the pair of handles and the box blank, the completed box in knocked down form collapsed ready for shipment appearing as illustrated in my preferred form in Fig. 1. It should be noted that part of each handle is secured to the outer surface of the main body walls of the box, while the extending or actual carrying portion of each handle is folded over to over-lie the end Walls, the handle attached box in knocked down form thereby coming within the same overall dimensions as an ordinary box without handles. It is also apparent that my process preferably involves a partial folding of the blank, then the application of the handles-and thereafter the completion of the folding operations.

Fig. 2a is a drawing of the handle blank itself. As shown, it includes the glue flap Ma, and the handle flap itself l-ib, which are articulated to each other. In the flap portion Mb, a hand hole flap M0 is demarked by a line of severance and a crease or score line as shown so that when a pair of handles are brought together in proper carrying position, the flaps Mo are free to swing along the score to either side, providing a space for the hand, and both an inter-locking and a cushion effect so that there are no sharp exposed edges to cause inconvenience. This will be clear from Figs. 2b, 3 and 3a,

Fig. 2 illustrates the preferred form of the box in partly erected condition. As the side walls 2, 2 are raised, the intermediate corner connection section as well as the side walls of the lid 6, ii are also brought into upright position, and the raising of these side walls simultaneously causes the corner sustaining flaps 8, 8 and 9, Q to swing into position against the main bottom and top panels of the box, as illustrated, serving to retain the box in upright position.

As the box is further closed, flap Nb of the handle which overlies the bottom wall 3, is also folded back from position adjacent the wall itself, so that the lid can be brought into closed position as illustrated in Fig. 3.

Figure 3 illustrates the box of Fig. 2 with the lid brought down into final closed position, and shows the handles extending outwardly from the box in carrying position. It may be noted that should it, be desired to use the box without using the handles (as for example in shipping the filled container), the two handles can readily be left flush against the outer surface of the front lid wall I, so that the box can as readily be tied or wrapped as if the handles were not present.

1 Thus my invention provides the maximum degree of flexibility in a store or other similar mechandising operation.

Fig. 3a is a partial end view of the box shown in Fig. 3. It will be noted that the hand hole fiaps I40 are folded to one side giving clearance for a grip, and that the folding of these two flaps in the same direction, provides an interlock to retain the box in closed position during the time the handle is in use. Furthermore, the hand is .not exposed to any out edge of the board, the

rounded under surface produced by the score line providing a cushioning effect. Actual practice has also shown this handle arrangement to be one of extreme durability, because the parts I la of the handles, are secured to the main body walls of the box rather than to the end walls. Thus there is no peeling or tearing action, and a box carried as shown in Fig. 3a, even with heavy contents, will readily withstand jostling and abuse, etc., such as is likely to be encountered in crowded subways and trains.

Fig. 4 shows another style of box in which certain Walls are not infolded, and the corner flaps do not act as wall-sustaining flaps. Figs, 4a, 4b, 4c and 4d illustrate the successive steps of the folding and gluing of this box, showing in stages 40 and 4d the application and folding of the handles according to my method. The finished box in knocked down form for shipment, with the handles attached to the respective walls, and with the reinforcement described in my Patent No. 2,145,682 is shown in Fig. 4. On this blank, the tabs 8 and 9, instead of being on the end walls, are articulated to the triangular end parts of the side walls, (which have been indicated as 213 and 5b and the tabs as 8a and 9a). The operational stages include turning the flaps Ba and 21) on the diagonal score lines to which they are articulated to the walls 2 and the flaps 6b and. 9a on the diagonal lines on which they are articulated to the walls 6. This is shown in Fig. 41). Next adhesive may be applied to the blank on the stippled areas, as shown in Fig. 4c. The box as such. is completed in knocked down condition by the inward folding of the walls 3 and I, as shown in Fig. 4d. The reinforcing strip 13 is also applied, in the preferred operation, to the adhesive area on wall 4; and in the practice of my invention, the handles I4 are applied and adhered to the walls I and 5 as shown in Fig. 4c and turned over with the walls 3 and I as shown in Fig. 4d.

The details of the machines for forming the cartons or boxes of Figs. 1 and 4 are not a limitation upon this invention. Since suitable mechanisms have been set forth in my previous patents as listed herein, 1 shall not describe in detail the various box making machines, their drives and their operations. In Fig. 4e which is the same as a like numbered figure in my Patent No. 2,145,682, I have shown one type of machine for forming the boxes of Fig. 4, which type of machine is more fully described in my Patent. No. 2,125,147. In general the box blanks I5 are carried from a feed hopper I6 by feed means I? and are traversed through the machine by a chain conveyor I8 provided with suitable dogs or abutments engaging a trailing wall of the blank which may be the wall 2 or the wall 6. At a portion of the machine indicated generally at I9 there are folding devices which operate to bring the blank to the condition shown in Fig. 4b. Glue is then applied to the blank by a suitable glue mechanism indicated generally at 251. The reinforcing strips I3 are withdrawn from a feed hopper 2| by feed rolls 22 and are carried downwardly by moving means 23. A mechanically actuated stop 24 holds a strip until one of the blanks I5 moves into position to receive it on the adhesive covered area of wall 4. This mechanism is located in the length of the machine as shown in Fig. 4e and centrally of its mid width. The handle applying mechanisms hereinafter described and illustrated in Fig. 4) will be located sidewise of the mechanism which has just been described for applying the reinforcing strips. A fuller description of the reinforcement applying mechanism is contained in my Patent No. 2,145,682.

The blank, still carried by conveyor I3, passes beneath a pressure gripping device indicated generally at 25, at a final stage where its end walls 3 and I are turned over inwardly by sweeps, one of which is shown at 26. Finally, the completely folded blank is delivered to a lower pressure belt 2! on which the blanks are stacked and against which they may be pressed by some suitable overhead pressing means 28.

In Fig. 4; I have illustrated the same machine to which a handle applying mechanism, generally indicated at 29, has been applied. Since two handles are to be applied to each blank, the

mechanism generally illustrated at 29 is duplicated in the machine, on either side, as will be readily understood. Also, the mechanism 29 preferably lies alongside of the mechanism 2 I24 for applying the reinforcing strips, illustrated in Fig. 46 but not in Fig. 4f.

In the handle applying mechanism 29, which is also shown on an enlarged scale in Figure 6 and in plan in Figure 7, I provide a swinging frame 3! which is pivoted as at 3 I. The frame is made to swing by mounting it on a bracket attached to the machine frame or on a shaft extending transversely of the machine and lying above the path of movement of the box blanks I5. The frame 30 has an arm 32 terminating in a cam follower 33 which bears against a cam 34 mounted upon a suitable shaft in the main frame and suitably driven from the machine drive in timed relationship with the movements of the conveyor I8. On the frame 30 there is mounted a feed hopper 35 in which the handle blanks I4 may be placed. An upper feed wheel 36 having the conventional rubber insert or its equivalent, and driven by the general machine drive, removes the handle blanks I4 one by one from the hopper 35 and delivers them to a lower belt 31. This belt passes over and is driven by a driven pulley 38 opposite the feed wheel 36 and moves downwardly in the frame 30 over a supporting plate 39 to an end pulley 40. An upper, cooperating belt 4| passes over an end sheave 42 near the feed wheel 36 and an opposite end sheave 43 near the end of the frame. The upper belt 1! may have pressure sheaves suitably mounted to hold it against the lower belt 31. Both belts may have tightening devices which are shown in the drawing but do not require special description. The frame 30 is provided with a glue pct 44 whence glue is transferred by a series of rollers 45 to a glue wheel 46. In the handle applying mechanisms the handle blanks lie in the feed hoppers with their glue flaps Ma disposed toward the center of the machine. They are withdrawn from the hopper in that position and carried downwardly between the belts 37 and 4| with their glue flaps projecting beyond the belts so that glue from the pot 44 is applied to the upper side of the glue flaps Ma of the handle blanks during their passage between the belts aforesaid.

As will be evident from a consideration of Figs. 4a to 4d, the handle blanks must be applied to the underside of the box blanks. To this end they must be moved from a position above the path of travel of the box blanks I to a position therebelow. Since the handle blanks are to be attached adhesively to the undersides of walls I and 5 and must underlie the walls 3 and l in the stage of the blank illustrated in Fig. 40, it is evident that the handle blank feeding and moving mechanisms just described must be located above portions of the box blanks 15. This is illustrated in Fig. '7. In the several figures the left hand end of the frame 30 is shown lying below the path of travel of the box blanks 15 as determined by the conveyor 18. In this position handle blanks, moved along by the belts 31 and 4!, are delivered to and come to rest upon a platform 41 suitably supported on the machine frame below the path of travel of the box blanks. But the handle blank feeding and moving mechanism can only extend as described below the path of travel of the box blanks during the inter vals between box blanks. When box blanks are passing beneath the handle blank feeding and moving mechanism, this mechanism must be got out of the way. This is the reason for the mounting of the mechanism upon the frame 38, the pivoting of that frame at 3| and the oscillating of the frame by means of the cam 34 acting on the frame arm 32 in timed relationship with the operations of the box machine and the movement of the box blanks.

When by the means and process just described a handle blank with glue applied has been brought to rest on the platform 51, it will be in a proper transverse position to be applied upwardly against a box blank I5 moving above the platform upon the conveyor [8. The platform $7 is formed with forward and preferably rearward raised edges to prevent displacement of the handle blank and is so shaped that the glued flap Ma of the handle blank extends beyond the platform so that it may be pressed upwardly against the box blank at the proper time in the movement of the latter. The handle blank is so pressed upwardly by means of a timed pressure wheel 48 which has a segment-shaped contacting surface. An upper timed pressure wheel 49 having a similar pressure segment cooperates with the pressure wheel 48, The pressure wheel 48 raises the glue flap of the handle blank up against the wall I or 5 0f the box blank against which it is firmly clamped by the coaction of the wheels 43 and 29. The stiffness of the handle blank causes that portion of it contained within the platform 41 to rise above the upturned edges thereof; and the pressure wheels 48 and 49, the pressure segments of which turn at the same peripheral speed as the linear speed of the box blank, cause the applied handle to move along with the box blank. To assure perfect adhesion a series of upper and lower pressure rollers 53 and 5! may be provided in the machine immediately following the pressure rollers 48 and 4d. By the time the blank has reached the gripping device 25, the handles will be firmly attached to the main body walls of the blank so that the portions Mb of the handles may be folded over on their score lines concurrently with the end walls 3 and 'l of the box, as has been described, by the sweeps aforesaid, one of which is shown at 26.

Fig. 7 shows only one of the mechanisms thus described and ends at the center line of the machine which is indicated at 52. At the opposite side of the machine another handle blank feeding, moving and applying mechanism will be provided which is a mirror image of the one illustrated but is otherwise as described. Also, as I have indicated, the reinforcing strip applying mechanism described in connection with Fig. 4e will preferably be located at the same point in the machine. This will provide three adjacent feed hoppers, two of them (35) will be for the handle blanks and one (2|) will be for the reinforcing strips. A single operator or machine tender can readily keep these several hoppers filled with blanks, and the location of the hoppers at substantially the same point in the machine facilitates his work. Indeed with box making machines equipped, as they frequently are, with an overhead platform, the location of these several hoppers permits an operator to keep them supplied usually without walking back and forth and in any event with a minimum of bodily movement. It is not essential, however, that these elements be located at the same point in the machine, or that the two handles be applied simultaneously with each other or with the reinforcing strip. The addition of the mechanisms described to any existing box making machine capable of operating upon the desired blanks, can be effected as desired.

Fig. 5 illustrates the first section of a two-directional machine for forming the boxes of Fig. l. The box blanks 53 are placed in a feed hopper 54 whence the are withdrawn b a feed wheel mechanism generally indicated at 55. The blanks are then moved through the first section of the machine on a suitable conveyor such as one or more chains 56 provided with lugs or abutments for moving the blanks. A series of folding instrumentalities indicated generally in Fig. 5 at 5'1 folds under the triangular portions 2a and 80. of the blank along their diagonal lines of articulation to the walls 2 and 6, bringing the blank into the condition illustrated in Fig, lb. Sweep means, one of which is shown at 58, then fold over the walls 2 and 5, together with their already folded triangular portions, as well as the sustaining flaps 8 and 9, bringing the blank into the condition shown in Fig. 1c. The series of pressure elements indicated generally at 53 may be employed to press the folds tightly; and a transfer mechanism 60 operates to transfer the folded blank to the conveyor of the second section of the machine, the end of which is indicated at Hi.

The second section of the machine, as shown in Fig. 5a, is provided with a conveyor indicated at 82, with a glue applying mechanism generally indicated at 63 and operating to apply glue as illustrated in Fig. 1d, with a gripping device 64 and means for turning over the end walls 3 and I of the blank with their already folded sustaining flaps 8 and 9. One of the sweeps for this purpose is shown at 55. The blank is thus brought to the condition shown in Fig. if and is delivered in stacked relationship with other blanks to a lower belt 66 against which it is pressed by an upper belt 61.

In Fig. a, which corresponds to the similarly numbered figure of my Patent No. 2,145,682, 1' have shown intermediate the glue applying mechanism 63 and the folding means 65 a means for applying the reinforcing strips I3. The strips are put in a hopper 68 whence the are individually withdrawn by a feed wheel combination 69. They are moved downwardly over a suitable belt or the like Ill and held ready by a timed stop I! When a box blank 53 is in the position to receive the reinforcing strip, the stop 1| moves out of the way and a driving device 12, operating in properly timed sequence with the forward motion of the carton blank IE (or conveyor [3) acts to apply the strip and to move it slightly ahead of the blank so that its leading edge comes under one of the connecting portions I0, I l and I2 of the blank as illustrated in Figs. 1, 1e and 19. The trailing portion of the strip !3 overlies the similar configuration at the trailing side of the box blank 53, all as is more fully described in my Patent No. 2,145,682.

Fig. 5b shows the application of a handle blank feeding, moving, gluing and applying mechanism similar to that shown and described in connection with Figs. 4 6 and 7 hereof. Like parts have been given like index numerals and the mechanism will not be redescribed. It will be understood as before that for the attachment of two handles, there will be another similar mechanism at the opposite side of the machine and preferably though not necessarily at the same point in the machine length, and also that the mechanism for applying the reinforcin strips may lie between the two mechanisms for feeding, moving and applying the handle blanks with the advan tages hereinabove discussed.

be moved upwardly and against the box blanks.

The handle blanks are brought to rest on a platen on which they are properly positioned by means 5 hereinafter described. When a box blank is properly positioned above a platen, the platen is caused to rise to apply the handle blank'to the box blank. Concurrently an upper pressure member moves downwardly so that the box blank and the applied handle blank are pressed together. Since the platen and the pressure member are vertically reciprocable, it is advisable to cause the box blank to come to rest at the position at which the handle blank is applied to it. The handle applying mechanism which I shall describe may be attached to either type of machine referred to above'or to other types of machine. In order to cause the box blank to pause in the machine for the attachment of handles, it is merely necessary to interrupt the conveyors I 8 or 62 in the described machines at the proper point by causing them to return over suitable sprockets, providing separate continuation conveyors to carry the blank on from that point, anddesynchronizing the conveyors to provide the required pause. This will be readily understood by the skilled worker in the art; but such an interrupted conveyor is illustrated and will be described in connection with Fig. 8 hereof. The pause in the travel of the carton blanks may be made as long as desired to permit the exertion of pressure against the adhesively joined handle and box blank so as to insure proper adhesion. A following series of pressure elements, rolls, belts or the like, to insure adhesion of the handle blanks to the box blanks may thus be eliminated.

In the second style of handle blank feeding, moving, gluing and applying mechanism which I am about to describe, I preferably provide for each such mechanism a first feed hopper with a delivery for carrying the blanks to a second feed hopper whence they are delivered to the mechanism which positions them beneath the box blanks. The advantages of this construction are two-fold. First, the second feed hopper maintains a supplementary accumulation of handle blanks so that the machine tender or operator need not be so accurate in keeping the first or primary hopper filled with blanks. Second, the first or primary feed hopper and its delivery mechanism may not only be angularly related to the second feed hopper and its delivery mechanism, but may be of any length desired. Since the delivery mechanism of the second feed hopper must extend substantially at right angles to the length of the machine section, the first feed hopper and its delivery mechanism may not only be caused to lie alongside of and parallel to the length of the machine section, but the first feed hopper itself may be brought to substantially any machine position desired. In this way, the first feed hoppers for the handle applying mecha nisms, together with the feed hopper for the reinforcing strip mechanism may be brought to a position above the path of travel of the box blanks in the machine and adjacent a transverse platform such as has been described, and with the advantages I have noted above. Excessive stooping, reaching and running about of the machine tender is thus rendered unnecessary.

The mechanism then,- illustrated in Figures 8 to 12, for applying the handles includes a primary hopper 13, in which a number of die cut handles '14 are placed in staggered or offset position. They are oriented in the hopper with the line of articulation between flaps lea and Nb parallel to the side walls of the primary hopper, and parallel to the direction of motion in which the handles are withdrawn from the primary hopper, as shown in Fig. 10. There is a continuously revolving primary underneath feed wheel 75, a frictional retard strip, and a primary overhead feed wheel E6, having located on the circumference thereof a frictional surface feed pad ll. There is a continuously moving underneath feed belt 18 with adjustable idler rollers l9, as shown. There may also be an upper feed belt Bil (see Fig. 8).

The shaft on which the primary overhead feed wheel is located is driven by a sprocket and chain from a shaft of the folding and gluin machine in conjunction with which my handle applying mechanism operates. The ratio is such that the primary overhead feed wheel makes one revolution for each blank that comes from the gluing machine from which it is driven, so that in this manner for every blank that advances through the folding and gluing machine, one handle is fed out by the primary hopper mechanism, due

- to the fact that the frictionally surfaced pad located on the circumference of the primary overhead feed wheel engages the uppermost of the series of handles in the hopper, bringing it forward between said pad and the continuously revolving primary underneath feed wheel. I'he retard, which can be of rubber or other suitable material, prevents more than one handle being brought forward at a time. A gear drives the conveyor belt and as the handle is drawn forward in the manner described, the continuously moving underneath feed belt continues to carry the handle and deposit this in the secondary hopper. As the handle is deposited in this secondary hopper, it falls by gravity to the base of the hopper or to the top of any accumulated stack of handles that may be located in the secondary hopper.

The secondary hopper 8i acts as a reservoir. Upon starting up the operation, a small stack of handles may be placed directly into the secondary hopper in addition, of course, to the handles placed in the primary hopper. Since, as previously explained, the primary hopper feeds out one handle for each blank that passes through the machine, it is obvious that whatever stack of handles may be initially placed in the secondary hopper will remain substantially equal in number; but if at any time the primary hopper should not function on one revolution, as for example, due to a slippage between the feed pad and the handle, the accumulated stack in the secondary hopper will still assure the handle being properly fed out for attachment to the blanks.

A second function of the secondary hopper is the transfer of the handle from the position above the line of travel of the box blank, to a position 1 below it. The upper end of the secondary hopper, in which the handles are deposited by the belt from the primary hopper, is located well above the line of travel of the blank, whereas the base of the secondary hopper, from which these handles are withdrawn, is located below the line of the travel of the blank.

The withdrawal of the handles from the secondary hopper and their positioning prior to application to the blank will now be described. Passing beneath the secondary hopper, there is a chain or chains 82, on which are located at spaced intervals lugs 33 (Fig. 9). The chain passes around the sprockets as shown, sprocket 84 being driven by shaft 85 which, in turn, is geared to the gluing and folding mechanism itself as illustrated. The gear ratio is such that one of the aforementioned lugs 83 on the chain passes beneath the secondary feed hopper for each box blank that passes through the folding and gluing mechanism, thereby withdrawin from the, base of the secondary hopper one handle in timed relation to each blank. The opening or orifice of the hopper is of such width that not more than one handle at a time can be withdrawn b the lug. The lugs are preferably tapered on top to facilitate the removal of the bottom handle since the taper tends to lift the stack and separate it from the bottom handle.

As the handles are carried along on chain 82 by the lugs 83, they pass beneath the overhead glue applying device which is best illustrated in Figure 9. This device consists of a glue pot or reservoir 88, and a continuously revolving glue roll 8?. There may be a suitable scraper blade which controls the amount of film on the glue roll. It is apparent that as the roll revolves, it will carry on its surface a film of adhesive from the reservoir, this adhesive film being transferred from glue roll 8?, to intermediate glue roller 88.

12 From this intermediate roller, the adhesive film is, in turn, transferred to the larger revolving glue applying wheel 89, the lower edge of which wheel is so located as to apply a strip of adhesive to the upper surface of flap I la of the handle, as the handle passes beneath the device. There are suitably spaced pads 9f! on the surface of the glue applying wheel to deposit the adhesive on the handles. The ratio of the circumference is 2 to 1 to the lug spacing, so that each pad istimed to one handle.

The handles with adhesive applied to the upper surface of flap 14a continue to be moved forward by the lugs on the chain; and, as best shown in Figures 9, 11 and 12, the handles now approach a receiving platform 9 I. This is mounted for vertical reciprocation in suitable ways on .the machine frame. At its lowest position, it is aligned with the chain or chains 82 to receive the handle blanks therefrom. The chains re turn around sprockets 92 on a shaft 93. This shaft bears one or more cams 94 which actuate fingers mounted in brackets $36. The fingers are pivoted to the brackets and have cam followers 96 engaging the cams 94, under the infiuence of springs 91. As a handle blank [4 is delivered to the platform 9|, the fingers engage the edges of the handle, and because they are traveling somewhat faster, they move the handle blank forwardly away from the lugs 83 as they return with the chain around the sprocket 92. The fingers also push the handle blank forwardly until its leading edge engages one or more pins 98. These pins are mounted in the platform 9| and are urged upwardly by springs 99, but are depressible downwardly, as will be understood. The fingers 95 remain in operative position, holding the handle securely against the disappearing pins 98 and retaining the handle blank in accurately located position to be applied to the box blank I5. It will be understood that fingers 95 return to inoperative position below level of handle on each cycle.

As best seen in Figures 8 and 10, the box blank has been brought to a position directly overlying the platform 9| by lugs Ian on a chain conveyor IOI. But at the platform, this conveyor returns over sprockets I02 on a shaft I03. Another conveyor I04 begins its conveying flight over sprockets I05 on the same shaft I83. While the conveyors IOI and I04 thus travel at the same speed, the lugs I06 on the latter are desynchronized with respect to the lugs on the former, so that the blank is left stationary in a position above the platform SI for a period of time dependent upon the relative spacing between lugs I00 and I66. By this arrangement, with no loss in the speed at which the box blanks are fed through the machine, a pause or stop is provided, during which pause or interval the handles are now applied, as will be described.

As most clearly shown in Figure 11, meansv are provided to lift the platform 9| to bring the handle into contact with the box blank i5. At the same time a pressure member descends from above to press the handle and the box firmly together. The adhesive previously applied to the handle now firmly joins the handle to the box wall. The platform and the upper pressure member are both preferably moved by toggle means, so that strong pressure may be applied. A toggle arm I0 1, pivoted at one end to the platform 9|, is pivoted at its other end to a toggle arm I08 which, in turn, is pivoted to a bracket I09 on machine frame IIO. At the point where the 13 two toggle arms are pivoted together, an operating member I I I is likewise pivoted. This operating arm is slotted, as at I I2, to receive the shaft 93; and a cam H3 is fixed to this shaft. The cam reciprocates the member III through the medium of a cam follower IM thereon. This mechanism is preferably duplicated at each side of the platform, as most clearly indicated in Figure 12.

The upper pressure member I I5 may be mount-- ed in ways H6 on the frame of the machine. A toggle arm II! is pivoted to the pressure member and to another toggle arm I I8 which, in turn. is pivoted to a bracket H9 on an overhead rail I29 of the machine. At the common pivot point of the two toggle arms, there is preferably a cam follower I2I in the form of a roller. This bears against a cam I22 fixed on a shaft I23 journaled in brackets I 24 on the rail I20. The shafts 93 and I23 rotate in synchronism.

The path of travel of the box blank I5 is sufficiently above the surface of the platform 9| in its lowermost position to permit the handle blankv It to be positioned, as hereinabove described. When the platform 9I is raised, the pins 98 are depressed by the box blank, but they serve accurately to position the handle blank until it is applied to the box blank. The pressure application of the handle blank, of course, is timed to occur during the pause aforesaid of the box blank I5; and the pressure is released prior to' the picking up of the box blank by the lugs I06 on the conveyor I04. The platform 9| descends, leaving the handle blank in adhesive union with the box blank, and the two then move forwardly on the conveyor I84.

Since, as hereinabove described, a handle blank is to be attached to the box blank at each side of the blank, the mechanism illustrated and described in connection with Figures 8 to 12 inclusive will be duplicated on each side of the box making machine, as will be readily understood.
