PAPER-Box MACHINE.

o all whomxit may concern:

Be itknown that I, CUN'CEY W. GAY, a citizenv ofthe UnitedStates of America, and 1 resident of -I/Vest Springfield, in the county of 5 Hampden andState of Massachusetts, have inventedcertain new and useful Improvements in- Paper-BOX Machines, of which the following is a full, clear, and exact description. i l0. This mlntion relates machines for folding b lzliiifs` of' cardboar sr,^,'afterl the same .have been p'rperlyscored, said blanks being supplied with a deposit of, gum for holding Y the opposite sides of the'blank together and thus forming"- cartons which .may be collapsed and staced into piles -ready for ship- 'ment,- and my invention has for one of its objects the provision-f an impro'ved machine, inwhlch the blanks to be folded are tplaced in a pile at one end thereof, and are ism of improved construction.

My inventionhas, furthermore, for its ob- -ject the provision of improved/blank-carrys Ling or transferring mechanism cooperative with Hap-bending devices whereby the flaps, are leftv in such a position relative to the body .I withj of 'acount-ing device for leaving 'a car-A ton projecting beyond the pile after a' certain number shall' have been' deposited on the table.

My invention also includes as one of its features aseries-of feeding and flattening rollers so organized tha/t the successive car-- tons will be transferred from a substantially level position into a-vertical position on the receiving table, thereby obviating the necessity of piling the cartons one o ntop of the other, vertically, and consequently rendering matter. Y

Further objects of the invention will be found in the particular construction and organization of some of the cooperating elements, as will be hereinafter' described an In the accompanying drawings in which Specification of Letters Patent. pplicativonj-jled September 14:, 19M.' Serial No. 224,441.

Fig. 8, is a similarviewshowing a modication of the flap-bending devices. Briefly stated, my improved machinehas at 'one end a pile of blanks, ,which are fed into the machine Aone by one, from the' bottom ofthe pile. The blank is then carried by al conveyer, past a gumming device whereby a marginal line of gum is applied to the-edge of one oftheblank flaps. During its advance movement, the blank is brought into contact with flap bending .de- 8O vices which turn the aps upward while the. body of the. blank remains flat, andis then carried into the path of a laterally-movable folder which first folds the i gummedv'flap down against the body, and' subsequently 85- moves the now partly-folded blank to a flattenin mechanism which becomes effect# ive'in fo ding-the other ap down upon thel gummed flap and finally presses the flaps tightly together.' The blank-which thus far v90 has been maintained a level osition, is now-carried by a series of squeezi g rollers to the Icarton-receiving table, upon which it will fall with one edge `down, .and body portion vertical, in which condition the successive blanks are pushed sid'ewise,` A until a certain number have Abeen 'thus' operated "upon, when this operation is interrupted and one blank is left undisturbed, therefore leaving the same'proje'cting beyond the car- 100 tons stacked on the table.

In the drawings, 10 .denotes a suitable fr ame,supporting in the vbearings 11, a driving shaft 12, carrying the pulley 13, to which movement may be imparted from any convenient source: Also mounted on this shaft is a. bevel gear 14' meshing with a similar gear 15 secured upon a transverse shaft 16, from which the blank feeding mechanism is operated. y

In order to,arrive at a clear understanding of myimproved machine, I will describe the of the pile.

several parts substantially in the succession in which they operate upon the blanks, a

-number of which are piled up near .the left end of the machine, (see Figs. 1 and 2,) and which are fed one at a time from the bottom for instance, as is clearly shown in Fig. 2, these blanks to be folded on longitiulinal score lines a I), after the .marginal lines of gum, or other adhesive substance, has been deposited 'on the under side of the flap c. The blanks are contained in a magazine formed by adjustable guiding posts 20, having slotted bases 21, which may be secured upon ,theframe of the machine by clamp bolts 22.

'The forward edges of the )ile of blanks are supported on a roller 25, anc the small outlet opening 26 will permit only the bottom blank to be removed from the pile. The rear edges of the blanks rest upon plates 27 having `blank engaging blocks 29 secured .upon a slide plate or yoke 30, which is held on a slide 31, slotted at 32, to permit the yoke 30 to be adjusted thereon as required.

Reciprocatory movement is imparted to the slide 31 from an eccentric. '33, mounted upon the shaft 16 and connected with the slide 31 through a connecting rod 34.' As

the'slide 31 is moved forward by the mechanism justdescribed the blank is carried forward between a pair of superposed rolls 40 and 41 mounted on shafts 42, 43, respectively, which are journaled in spring pressed boxes carried by the frame 10, the lower shaft 42 being constantly driven by a sprocket 44 secured thereto, 'and a chain 45, actuated by a sprocket 46, which is mounted Aupon the shaft 16 above referred to.

lia'lhe roller 40 constitutes a pulleyfor an 'is/journaled in bearings provided therefor on 4 a gum box 54, which may be of any suitable construction. l l

Practice has demonstrated that the sides ,of

" the disk 52 are apt to carry a'n over-abundance of gum, and throw the same about promis- .cuously, and for that reasonrneans are shown whereby the sides of the disk will be relieved of the gum, leaving only. the peripheral face of the disk supplied therewith,v and such means include a pair of scrapers 55, the lower 1t is, of course, presupposed that the blanks are properly cut and scored,

edges of which are in contact with the sides of the disk, andv whichy are supported on'a bracket 56 securedy upon the frame 1() 1n any desired manner g and, in ord er to.prevent^too great a quantity vof gum to be deposited upon the lower surface of the blank flap., c, l have provided a doctor blade 57, held for sliding motion in the bracket 56, and capable of being adjusted relatively to the periphery of the disk 52, as, for instance, b'ya screw-58 having lan annular flange 59 entering a slot 60. in the doctor blade, thel screw 5S being in screw-threaded engagement with the bracket 56 as clearly shown in Fig. 6.' l

The space b'etween the rollers 5() above referred to is substantially equal to the tlii'ck.-` ness of the roller51 and for this reason it will `be evident thatfas the blank is carried between the rollers 50 'and 51, the gum which is deposited upon the under side of the blank flap, will not be spread or squeezed. ou't'laterally ofthe line which is to` be gummed', so that the deposit of gum will always be conlined to a certain predetermined width.

Rigid longitudinally-extending bars 60 are provided to support a plural-ity of belt back-l ing rollers. 61, journale'd in the brackets 62, -which may be adjusted. on the bar longitudinally as wellv as vertically, to coperate with a series of rollers 63, which are j ournaled in a bracket 64 secured upon the frame 10, and constituting supporting devices for the belt conveyer 47 above mentioned.

By referring to Fig. 3, it will be seen that the rollers 61 and 63 are staggered, so that when the rollers 6] are properly adjusted vertically thev may cause the adjacent runs 'of the belts 48. and 47 to follow a sinuous path,4 and that, therefore, the belts need Vnotnecess'arily be very tight to cause sufficient friction for carrying the blank. Thel aforementioned adjustment of the series of. rollers 63, may be accomplished by bodily and individually vertically moving the brackets 62l for such rollers 63, as may be done byproviding vertical slots 60"' through the supporting bar 60 for the brackets, and through which slots the bolts 60 are passed with ascrew thread engagement into the wide upper .portions of the brackets. These belts ,transfer the blank beneath a pair of swords 70, which are disposed substantially in alinenient with the score lines f1. l), and serve to hold the body ol the blank at those lines while the flaps are being turnedk or bent upward. This bending operation takes place gradually, and is effected in a preparatory manner by as an example a pair of bending disks 71, having their peripheries projecting above the plane of the blank, and

upwards as'the blank passes 'above them. Another pair oll bending disks 72,'the distance between which is less than that between the disks 71, is provided a short distl-ufrefore causing the [laps to be slightly bent tance vbeyond the'previouslset of disks, so

that the laps will be still more bent upward until they arrive substantially in 'a vertical position relative to the bodyprtion of the.-

blank, which now appears'folded into.a -U form.- Each blank, as it is carried forward by the conveyor belts 47 and 48, is projected v upon a table 7 5' upon which itcomes-to .rest

against a stop 176, the Kflaps ofthe blank being heldv in a vertical folded positionby guards 76, rigidly secured tothe-iframe of the machine. The next operation f on. the

blank will be that vof Vfolding the gum 'flap downward against tliejbodyportion of the blank, this operation being elfected by a folding mechanism which is clearly shown in Figs. 4 and 7 of the drawings. -..Secured to the frame 10 is a bracket 80, the'upper end of which is disposed horizontallyl, to-v form the table 75 above mentioned,` .and

mounted forvsliding movement on this table.

is a slide 81 which'may bevnormally pulled Vrearward by a .spring 82, such rearward movement being limited by astop 8 3 which table 75. '(See Fig. 7.) Pivoted'near, the." .forward end of the`slide81jis a folding blade and arm 88, as will bereadily understood."

is adjustable as shown, and ixed on .the

84 having a limited opening movement on said slide, .and operable in both directions by aca'm 85,l mountedl uponfa shaft'12 act-- ing on rollers 86 whielifare journaled onfa rod 87,'the free end o f which is attached to. .an arm `83 -mounted upon a' shaft 89 which is journaled'in-a bear1ng90 constituting a part of thebraclet 8 0. jAlso secured tof' the shaft 89 is a lever 91, the 'upper en d `oft-which is connected through the interventionof a link 92, with the -folding .blade 84 above mentioned, and the angular movement of.

which may. be varied by properly adjusting the point of connection between the rod 87 In Fig. 4, thefol'ding blade 8 4 issh'own'inv its retracted position', an'd'about to engage and f old downward to the blank lflap around theA scoreline a, which, as has been previously stated, has a marginal line of gum on'what was formerly `'its under side but which is overturned to become its lupper side, and which,`in thel Kresent position, 4is that lnext the folding b ade 84, As the shaft 12,-is rotated, the' lever 91 will be moved'- to cause the folding ,blade. 84 to`A fold the vblank flap downward. as ind'icated'lbythe arrow y, Fig. 4, and as'soon'as 'thefolding blade has arrived in its downward position, the slide 81 will b e moved .bodily'forward horizontally on .the .table 7 54 causing the other Hap of theblankto'be folded n top of the previous flap, such blank swinging as i-ndicated by arrow this action being directly eected by the "impingerne'nt .of the flapv against a stationaryfolding blade 93 ad-A justably secured in any convenient manner to the frame. It will be appreciated that the folding blade-.or `wing`84 has compound movements as follows z-it first swings downp osition to fold wardly to. the horizontal down the flap a-of the vbla (during` which downswinging ofthe blade the slide on which the bladel is vpivoted 4remains immovable,-

being-res'trained by the spring'82) and thenv the'movementof v the lever 91 continuing zont'al position",- the blade' and slide are,-

`throughV the link 92 connecting the blade. and

.after the blade has `beenswung to .the horilever 91,-move'd horizontally together, the

forward'edge .ofthe slide-.by its engagement. with the folded edge of the blank forcing the- .partially folded blank under the stationary folderl blade '93. The blank, theflaps' of which havev been folded 'in the manner del scribed, will then be subjected to theaction'- of a pair fof coperative pressing rolls 100 and.

101,*the former, 100, of whih is journaled in the A'stationary bearings'. held in a pair --of auxiliaryv f'ramesi102, l while vthe Alatter,1 (v)1,

posited upon a carton-receiving table with o ne of their edges resting thereon, and means are .provided for diverting the thus 'farhori previously stated, the blanks are, after being folded,-de

zontal path. of the blank into a vertical one, l

fthese means consisting substantiallyfof'a set 'of compressing rolls designated in a general"V ,Way by 103. and 1'04 respectively, and bein .similar in lconstruction to the rolls an -101 above' described, andfalso -serving asady ditional devices for insuring a perfect con-'f tactl between the flap portions to be united bythe -deposit of gum. f" The several'sets'of rolls, ,100, 101,`103,'and

-104 arel referably geared together inthe, -manner s o'wn inFig. 4, in which a gear 160 onthe'lowerroll-lm, is illustrated in engage# 'ment Witha'gear'll for driving. the upper 'roll 103,'while-anothergear 162 drives the lower roll'104, thuspreserving thefunifol-m vdirection of rotary movement for-the pur- .set of ressing rolls'104, it will lie-dropped 'vertica y onto. a carton-receiving table4 105, having a sliding weight 106,- longitudinally movable thereon'and adapted' to be gradu ally forced rearward bytheaccumulating cartons -on the table. Each blank, as it drops onto the table, willpass and come to rest inA front of a pusher 107, (see Figs, land 4) comprising ahorizontally-disposed arm 108 whichmay be) slotted toreceiv'e, in-'s'uit ably adjusted positions thereon, one ormore pusher blades 109. The pusher lever 107 is preferably'pivoted on a bracket 110 secured lio - serai-r1 1. sints in the 'forcing of successive blanks beueath and past a d ltent 113, pivoted on an angle bracket 1.14 1.02, and also above and beyond a pair ol' gravita-tive detents or by passes 115 pivoted in the table 105, these by-pa ses serving to retain the blanks in their pushed-forward position, and, therefore, avoiding inteference with the subsequently following folded cartons as they are discharged 'frein the rolls 104. y I

` In conjunction with the delivery portion of the machine, last described, a counting mechanism employedwhereby one blank will be left projecting beyond theothers after a certain number thereof have been deposited'on the table. This counting meehanism is clearly shown in Figs. 1 and 4, in which it will be seen that a bar 120 is guided by blocks 121 secured to the frame in a suitable manner, and reciprocatory movement is imparted to it by. a lever 122, fulcrurned at 123 to the frame, and having a roller 124 in engagement with a cam 125 on shaft. 16 whereby said lever 122 is. pushed toward the right as seen in Fig. 1, while a spring 126 may be em lloyed for moving the bar 120 toward the le t. This bar constitutes the medium .whereby the successive blanks, as they drop this purpose being shown herein as a finger 126, adjustably secured on the bar 120, as, for instance, by screws 127. The right hand end of the bar -120 has a pin 128 adapted to be engaged by a stop plate 129, which is secured uponI a disk 13() made in the form of a ratchet to which a step by step movement may be imparted by the mechanism to be hereinafter described. In .the present instance Ihave' shown the ratchet wheel as having 25' teeth, and during` the advance of 24 of such teeth, the bar 120 may reciprocate with perfect freedom and without meeting any obstruction. At the 25th tooth, however, the plate 129 will project into the path of the pin 123 during its movement from .right to left, as seen in vFig. 1, so that, concartons shall take place accurately, or,in`

other words, Athat'the counting device shall operateA only as blanks are passing through cured to the side frame the machine, means are provided for nor malle retaining the ratchet wheel 130 inli 'i motion lbeingimparted thereto only as i: blank is actually passing through'the ma The mechanism employed for achieving this result is clearly shown in Fig..

4, in. which what may be termed a"feeler' ,is disposed directly in the rear of the rolls 100 andv 101. Thisfeeler 131 is .mounted upon a spindle'132 pivotally.supported on a frame and having' a counterweight 133 for normally throwing the lower vend of the feeler 131 toward the rolls 101, as seen in Fig. 4. The spindle 132 is also provided with an arm 134, which 'is connected througha link 1135 with a pawl 136 pivoted at 137-on an arm 138, the pivot axis of'which is concentric with that of the ratchet" 130, and ,which may be operated from an' eccentric 139 (see Fig. 1.) mounted upon the shaft 12, and connected with said arm by a rod 140 of usual construction.

The descriptionjust given clearly shows.

that a constant oscillatory movement will be imparted to the arm 138, while, however, the ratchet wheel 130 will not be operated unless pawl 136 has been lowered into position. by a Y blank striking the feeler 131, so that a movement of the ratchet wheel 130fcan only result when the blank is passing between rolls 100 and 101. i

1n Fig. S l have shown 'llap bending means which may be employed in substitution of the rollers 71 and 72, the present construction including a pair of benders 150 mountedwith their rear ends upon a spindle 151, which ma)v be suitably journaled horizontalljTY and transversely in the framel 64. The active p bending portions of the lever-like benders 150. are substantially horizontal and terminate in dowmvardly extended ends 152, which may be secured to a cross bar-153 in the manner shown in Fig". S.' A rising and falling movement is imparted to the bar 153 by a pair of arms 154 and ,155, niounted'upon a stud 156,

which may be journaled in a suitable bearing held on a frame. The lcver-like benders, are swung in parallel vvertical planes bya cam 157, mounted upon shaft 16 and engaging a roller on a thrust rod 159, which is connected vwith the aforementioned arms 155. The le ver-like benders, mechanically and positively thelblank against the stop 76, and inasmuch' A yas practice has demonstrated that the blanks are apt to jump upwards after leaving the oonveyers, means are provided whereby the.

`blankis not only/prevented from leaving the table, but whereby, furthermore, its movement will be frictionallv affected. These means consist substantially of a guard plate 180, (see Fig. 7) disposed at a sufficient height from the folding table 75 to avoid interferenee with the upturned fla s of the blank, but yet will prevent the b ank from jumping, and at the same time constituting a stationary' surface on which the ii-ap edges may travel and thus retard the movement of the blank.

' of an ang-le bracket 184, secured to thefold-` Since the guard plate is comparatively large and for that reason coversmany parts ofthe machine which vit is especially desired to illustrate, the plate 180 has been omitted from the general views, and .its form and application has been clearly' shown in Ilig. `7,

particularly drawn for that urpose. Here the late is shown ,provide with'a downwar( ly projecting ear 181, carrying a clamp l bolt 1,82 which may be adjusted in a slot 183,
