BOX-ASSEMBLING MACHINE.

Specification of Letters Patent.

Patented J une 1, 1915.

- Application filed July 2, 1914. Serial No. 848,530.

- citizen of the UnitedStates, residing at Chil0. 'bodies by means operating at high speed,

cago, in the county of Cook and State of Illinois, have invented certain new and usefulImprovement-s in Box-Assembling Machines, of which the following is a specification.

The salient feature of the present invention is the assembling of boxcovers on boxthereby performing such function with rapidity and despatch.

The improved machine incorporating this invention, although not limited to such use,

is especially applicable for placing covers telescopically on necked or collared pasteboard boxes of rectangular shape, such for example, as are ordinarily used for. cigarettes.

In the preferred embodiment of the invention, the boxes and covers are fed in series toward one another in opposite directions by suitable means, each cover being brought into register with one of the boxes and applied thereto by first fitting one end of the cover over the neck, but not pressing the same home on the box, then turning the cover down over the box so that its sides fit over those of the neck, and then spreading slightly or guiding the opposite end of the cover, and while in this condition, closing it over the corresponding end of the neck, subsequently pressing the cover full down on the box so as to completely inclose the neck and bear against the edges of the box-walls proper. That is to say, the manner of applying the cover to the box by this mechanism is slightly analogous to the method of fitting a' low shoe on the foot by means of a shoe-horn.

One particular feature of advantage in a machine of this character resides in the fact that the covers are applied to the boxes during the uninterrupted travel of both elements, whereby the assembling is brought about at an economical high speed of operation of the machine.

A preferred embodiment of this invention in a machine is illustrated in the accompany ing drawings forming a part of this specification, a detailed description of the structural elements of such machine and their functions being given below.

In these drawings: Figure 1 is a fragmentary elevation of the machine; Fig. 2 is an end elevation of the same; Fig. 3 is a'substantially central vertical cross-section on an enlarged scale; Fig. 4 is a fragmentary elevation of the lower portion of the mechanism on an enlarged scale; Fig. 5 is a crosssection on line 55 of Fig. 4; Fig. 6 is a cross-section on line 66 of Fig. 4; Fig. 7

is an enlarged view of the portion of the mechanism where the box-elements are brought together for assembling; Fig. 8 is a similar section illustrating the partial closmg of the cover on the box; Fig. 9 illustrates the positions of the box elements prior to that which they assume illustrated in Fig. 8. Fig. 10 the next step in the closing operation after that shown in Fig. 8; Fig. 11 shows the box completely closed; Fig. 12 illustrates in perspective a series of curved fingers which rock the box-cover in the closmg operation, and Fig. 13 is a fragmentary detail illustrating the means for bringing the box-elements sidewise into exact register.

This machine comprises a hollow-base or standard 20 on which the greater portion of the mechanism is mounted. Projecting forwardly from the upper part of this standard and rotatable in suitable bearings therein are two shafts 21 and 22 equipped with driving-gears 23 and 24 respectively, shaft 21, (by means of mechanism not necessary to describe), being adjustable to a slight degree toward and from the shaft 22. Carried by and grouped around these two shafts are the principal parts of the machine performing the box-closing operation, that is, the assembling of the box elements. The teeth of gear 24 are in mesh with an intermediate gear 25 mounted on a shaft 26 revoluble in hearings in the standard, (Fig. 3). Gear 27 611 shaft 28, (Figs. 1 and 3), rotatable in bearings of the standard, is in mesh with the teeth of gears 23 and 25 and also in mesh with the drivingpinion 29 on shaft 30 which at the rearof the machine, as shownin Fig. 2, is supplied with a drive-pulley 31 which may be belted up to any suitable source of power, such as an electric-motor. Obviouslv then, the rotation of pulley 31 and shaft 30 is transmitted through the train of gears so as to rotate the shafts 21 and 22 in opposite directions, the former clockwise, and the latter' counter-clockwise. Shaft 21 has fastened thereto and revoluble therewith, a.

pair of spaced disks 32 and 33, (Figs. 2 and 4 3), each having an inwardly-extended flange or circular rib 34 and 35 respectively, to the inner faces of which are fastened the pair of disks 36 circular in general conformation, but also provided with a plurality. of fiat faces 37, those of the two disks being in angular register. Centrally between these disks 36,-and which may be held in position by circular-flanges 38 on the disks, is a sprocket-wheel 39 in cotiperative relation with a sprocket-chain 40 pro vided at intervals with outstanding lugs or fingers 41, 41, adapted when they pass around the shaft 21 to be in register with the flat faces 37, as shown for example in Fig. 8. This sprocket-chain, some distance away from the standard 20, passes around another sprocket-wheel, (not illustrated), as is customary. Chain 40 passes between a pair of supporting-strips or bars 42, 42, (Fig. 2), on which the necked, rectangular cigarette-boxes are adapted to slide, be ing ushed along by the upwardly-projecting lhgs 41 until they reach the compositewheel, made up with the various partsdcscribed, on the shaft 21, and then each ox rests upon two of the surfaces 37, its rearedge bearing against its coiiperati ng stop 41 on the chain. This 0 eration is perhaps best illustrated in Fig.

For each pair of the fiat surfaces 37 I pivot on each of the disks 32- 'and 33 at 43 the arms 44 and 45 (Figs. 3 and 7 these arms at one end being cross-connected together b the: shaft 46 accommodated in curved s ots 47 of the two disks. These arms 44 and 45 are pivoted on the inner faces of the disks 32, and 33 and extend through'suitable openings48, (Fig. 3), in

. back against the lug 41 on the chain, that is,.they prevent the box from slidin forwardly or downwardly and also limit the extent of application of the cover to the box until they are withdrawn. In order that they may perform this function, each pair of these arms 44 and 45 is supplied with a coil-contractile-spring 52, (Fig. 1), fastened to the arm 44 and also to the disk, the contractile action of the spring swinging thearms on their pivots 43 and holding them in the position illustrated in Fig. 7.

The disk 32 opposite each of the pair of flat surfac s 37 is equipped with a boss 53 (Fig. 13) siidingly receiving a pin 54 con- I nected to a leaf-spring 55 tendin to retract -application of the box-cover.

order to position each of the boxes sidewise just prior to its reception of its cover, I mount on the machineframe an outwardly projecting stud-shaft 56, the outerend of which has a plate 57 fastened thereto, to which is secured a bent-arm 58, (Figs. 1 and 13). As the boxes and pins 54 come into register with the end-portion of the bar 58, the latter pushes the pins in, as shown in Fig. 13, and forces the boxes over against the disk 33, in this way'properly positioning and gaging them for the reception of their respective covers.

In order to actuate the pairs of arms 44 and 45 I mount on the machineframe a bent-support 59 carrying on its inner-face a cam-block 60 with which rollers 61 on the protruding-ends of the shafts 46 are adapted to coiiperate. That is to say, as the rollers ride on the surface of this cam, as

illustrated in Fig. -1, the arms 44 and 45 will swing on their pivots so that their boxthe corresponding lug 41 of the chain, permitting the free and ready transfer of the boxes from their stationary supporting- bars 42, 42, to the flat-surfaced rotary-disks 36. As soon, however, as therollers pass off of the end ofthe cam-block 60 the arms 44 and 45 swing on their pivots under the action of their springs 52 so that'the teeth 49 engage the box-neck or collar just above the edge of the box-wall and hold the box against the traveling-stop 41. After the box has received its cover, as explained hereinafter, it is necessary to' retract the pro truding-ends of the arms 44, 45, and their teeth or fingers 49 to permit the discharge of the box, and this is accomplished readily and easily by means of a stationar -bar 62 having an inwardly-bent end 63, Fig. 3). When one of the rollers 61 strikes the stop 63 during the rotation of the shaft21 and the parts carried .thereby the roller willbe temporarily held against movement andthe turning of the disk 32'Will cause the arms 44 and 45 to swing on their pivots out of the way of the box, the shaft 46 traveling in the slots 47. As soon, however, as the roller leaves the stop 63 from which it passes after a momentary detention the arms 44 and 45 swing back to normal position under the influence of their springs, as. will be readily understood.

The mechanism mounted: on and rotatable With the shaft 22 is much like that on the companion shaft 21, the shaft 22 and its parts being provided for the conveying and This structure comprises the inner and outer disks 65 and 66 respectively, the flat-surfaced disks 67-, the forward-end ofeach flat surface of which is provided with a stop or gage-pin 68, and the central sprocket-wheel 69, the parts being all clamped or fastened together in any suitable or approved manner. A sprocket-chain 70 with spaced-lugs 71 cooperates with the wheel 69 and another sprocket-wheel (not illustrated), spaced away from the shaft 22 some distance. As in the previous instance, the lugs 71 convey the box-covers on suitable stationary-supports until they arrive ,andbecome positioned on the flat surfaces of the disks 67 and as they rotate downwardly they slide into contact with the stop-pins 68, as illustrated in dotted lines in Fig. 8. As is illustrated in the various figures, and in perspective in Fig. 12, the appliance is equipped with a member 72 suitably supported in osition so that its four upstanding-fingers 3 with bowed or bent-ends 74 are spaced between the disks 65 and 66, the disks 67, and the sprocket-wheel 69, so that their bentends are in the position illustrated in Fig. 8. The companion box-conveying structure is provided with a stripping-device 75 suitably supported in any approved manner and having a pair of upwardly-extended curved tongues 76 spaced between sprocket-chain 40 and the adjacent box-element supportingdisks 36 so that in their downward travel the boxes are compelled to leave the rotary mechanism and travel downwardly between the member 75 and the fingers 73 of the oppositevmember 72, (see Fig. 11). 7

In order to make certain that the boxcovers will travel forwardly against the gage or stop-pins 68 and away from the chain-lugs 71, I provide an air-blast to assist gravity in such movement of the boxes. This mechanism comprises an oscillatory air-pump 77, (Fig. 2), mounted on a bracket 78 secured to the rear of the main-frame, the piston of the pump being connected by a rod 9 with a crank-pin 80 on a disk 81 secured to the oute end of shaft 30 beyond a hearing 82 b zed to the main-frame and assisting in the support of the shaft. Also mounted on the top of the machine and adjustable by means of a bolt 83 a bracket 84 is provided carrying a curved-plate 85 extending over the path of travel of the box-covers. This plate is equipped with a nozzle 86 connected by suitable piping 87 with the airpump 77. The operation of this part of the mechanism is as follows: When the boxcover 88 reaches the position substantially as indicated in Fig. 8, if it fails to slide forwardly against its stop-pins 68 under the action of gravity it will be subjected to a blast of air, which, playing upon the interior of the cover, pushes it forwardly into position, the operation of the air-pump being so timed as to deliver these air-blasts in proper timed relation to the travel and position of the box-covers.

On the stud-shaft 56 a collar 89 is loosely mounted and has attached thereto by means of a s rew 90. one end of a coil-contractile spring 91, the other end being fastened to any suitable stationary part of the machine, as for instance, the bracket 84 or plate 85. Collar 89 carries a depending, thin, flexible, metal-spring 92 with a hook-end 93 adapted as explained hereinafter, to assist in the application of the covers to the boxes, fitting between the boxes and covers and expanding or stretching the latter slightly, or guiding them to facilitate their application.

The stationary-plate 57 described above and mounted on the shaft 56, has fastened thereto a depending bar 94 corresponding in construction and function to the bar 58 and cooperating with the spring-pressed guiding or gaging-pins 95, in construction and purpose like the pins 54 of the companion mechanism.

The assembled boxes and covers upon leaving the conveying mechanism, as has been explained, pass down between the parts 75' and 73 and are prevented from. lateral displacement by a pair of oppositely-disposed upstanding'bars 96 and 97 (Fig. 3), and if desired, the member 75 instead of being rigidly supported may be rockingly mounted on a shaft 98, (Fig. 4), and equ pped with an adjusting-screw 99 bearing against a bifurcated arm 100 hung on the shaft 98 and carrying at one end a roller 101 cooperating with a cam 102 on. a rotatingshaft 103.

The discharge-mechanism for the assembled box-bodies and covers forms no part of the present invention and needs no description except the statement that the horizontal passage has a retarding-brush 104:, a reciprocatory delivery-plate 105, and a cotiperating plunger 106. This mechanism is described and claimed, in my co-pending application, Serial No. 779,486.

Operation: The operation of this im proved mechanism is substantially as follows: The cigarette or other box-bodies 50 are advanced to the assembling-portion. of the mechanism by means of the sprocketchain 40 and its spaced abutments or shoulders 41. W'hen these boxes reach the central portion of the machine, each bears on a pair of fiat surfaces 37 of the rotary member with which the sprocket-chain co-acts. When each box-body reaches the upper-portion of the rotary-mechanism mounted on shaft 21, its corresponding positioning and cover-limiting arms 44, 45, are retracted against the action of their spring 52', as illustrated in Fig. 1, by the engagement of their roller 61 with the stationary-cam 60. As the box-body advances, however, and the shaft 21 turns, the roller 61 rides 01f of the end of the cam 60, permitting the arms 44, 45, to respond to the contractile action of the spring 52 and turn on their pivots 43 so as to engage the box-neck just above the edge of the box-rim, as illustrated, for example in Fig. 7 thereby holding the box in proper position against its abutment 41, preventing it from falling forwardly as it passes downwardly around the axis of shaft 21. Just before it reaches the position for the application of its cover, the arm 58, by engagement 'with the corresponding springpin 54, positively pushes the box over against the guide 33 into proper position for registration with the companion cover. During such advance of each necked or collared box-body, its companion cover is be ing advanced toward the body by the sprocket-chain and the corresponding abutment or lug 7]. carried thereby, it being understood that the bodies and covers are both advanced continuously in series so hat the machine may operate with a high degree of elliciency and at relatively high speed. As the box cover begins to turn down as it travels around the .haft 22, it either talls forwardly by gravity into contact with the stop or gage-pins 68, or else it is pushed into contact with such pins by the blast of air which is periodically emitted from the nozzle 86. As it continues its i'orward downward travel, its springpressed pin it is pushed inwardly by the stationary-bar 34 so that the cover is brought sidcwise into proper register with the companion box.

As each box and its cover approach each othri and travel downwardly around their respective shafts 2i and they reach the positions indicated in Fig. 7, that is, the lower end of the cruel is brought into register with and fitted over one end of the neck, being prevented from being com pletely applied at this end by the presence of the limiting lingers or lu s alil, which de termine the extent of the telescopic application oi he rover to the box. It should be noted that the spring-linger 92 projects inside ol' the b x, as illustrated in this figure.

As the partially assembled box and cover proceed dounwardlv, the fingers or lugs lit remain in the same position, because they are carried by the rotary men'ibcr mounted on the shall 21. and as the parts move downwardly, the cover 8 strikes the convex ends Tlot' the bar Ti which cause it to lflt'li or turn over on to the box-neck in substaut'ia lv the manner illustrated in Figs. 7 and and. since one end of the cover had been previ ush applied over one end of the neck, no dillicuity is experienced in applying the r ver owr the sides of the neck. as it is turned down as described. \l'hen the roller (Bl strikes the stationary abutment (iii, the arms, H are rapidly rotated on their i'ulcrums l3, removing the fingers or lugs 49 from between the cover and box, the parts being illustrated in Fig. 8 in the positions they assume just previous to such retraction of the fingers and in Fig. 10, the position which they take just after such retraction. This, of course, permits the complete telescoping of one end of the cover over the advance end of the box, and during 70 the further downward movement of the parts the hook 93 of the resilient arm 92 engages the end-wall of the cover and extends it slightly to facilitate its application over the end-Wall of the neck, as illustrated in Fig. 10.

As the assembled box and cover pass downwardly between the guides or arms 73 and 75, and 96 and 97, the cover is'pushed fully home on the box so that as the latter emerges from the lower end of this pasthe box-elcments are completely'assembled. If necessary or desirable, the bar 75 may be given a slight rocking movement by means of the cam 102 acting on the roller 101, as will be readily understood, but this is frequently not necessary.

As the shaft 21 and the parts carried thereby continue their rotation, the roller 61 passes off of the abutment 63, permitting the arms it 45, to respond to the action of their spring 52, and as the roller 61 travels upwardly it again engages the fixed-cam ti rocking the arms 44, 45, for the reception between them and one of the abutments 41 on the chain 40, of another box 50.

It might be noted that the spring 91 acting on the arm 92 aids in retracting the arm from engagement with the end-wall of the cover as soon as the hook 93 has extended the cover sufficiently to permit its ready application over the end-wall of the neck.

it should be clear from this description and illustration that the box-bodies are fed forwardly in a continuous series and that the box covers are advanced toward them in the opposite direction in. a continuous series and in such timed relation that the covers will register with the individual boxes and be applied thereto over the colo lars or necks in the manner indicated and that the assembled boxes and covers will he delivered from the lower. part of the machine in a continuous series and discharged from the machine by mechanism unnecessary here to detail.-

Of course, many minor mechanical changes may be made in the mechanism shown and described in detail herein Without departing from the substance of this invention and without sacrificing any of its material benefits.
