Applicationled January 16, 1,906.l Serial No. 296,306.

State o f New York, have invented certain new and useful Improvements in Paper-Box Machines, of which the following is a speciv` iication. t e 4 My invention relates to machines for making paper boxes, and has for its object to improve and simplify the construction of such machines and make them capable of makin complete boxes from a continuous web o paper, and to-these ends my invention consists in the various features of construction and arrangement of parts having the general mode of operation and producing the general results, substantiallyas hereinafter more particularly set forth. y

Referring tothe accompanying drawings, wherein I have illustrated a preferred embodiment of my invention, Figure 1 `is a side view, partly in section, showing a-portion of the machine embodying my invention; Fig. 2 is a side 4View showing .a further portion of 'the machine; Fig. 3 is an enlarged longitudinal sectional view through the plunger and die portion of the machine; Fig. i is a plan view of the same; Fig. 5 is a transverse sectionalelevation showing .the plunger and die; Fig. 6 i's` a detail view ofthe stop motion device; and Fig. 7 is a diagramshowing the various operations upon'the web in for-m- While my invention may be used for making many and various forms of boxes or receptacles,. the parts thereof being modied or changed in construction and relative relations or adjustments to suit the requirements of any particular case, I have shown myinvention embodied in a machine adapted to make trays or more particularly receptacles having a bottom and sides and ends secured together,with an open top, and these may be used separately or two of them together to make a'complete telescoping box, but it is understood'that other forms of trays or receptacles can be made wherein the cover is an integral part of the box body.

One of thel main objects of my invention is to provide a machine which is capable f .performing allthe necessary operations in making the complete boxes or trays from a f 'continuous web of paper, including the Specification ofY Letters Patent. Patented Jun@ 2 t, ie

is performed on .the webv in its passage through the/machine, cutting and sco-ring the same, applying adhesive material to the proper parts, folding, pressing `the folded parts together and vdelivering the completed box.

The various devices for performing the various functions are made adjustable with relation to each other so that boxesor receptacles of different sizes can be made by changing or substituting some` parts, as for instance one set of dies for another, and ade justing the relations of the other parts.

Experience has taught me that when a web of material is ldelivered to a machine ofthis character and manipulated in the manner set forth, it is exceedingly advantageous to use a rotary printing apparatus which is continuously operating, lwhile v of course many of the other 'operations are intermittently performed, necessitating that the web be in a state ofrest during. said operation.

So, too, in "intermittently feeding the webA` to submit it to different operations, it is absolutely necessary, in order to make goed work and produce proper` register between the various operations performed on the articles, to feed the material the 'exact amount necessary at each movement, for if the error 4in feeding is only slight it is rapidly multiplied so that the parts will not properly operate 'to perform their functionsvon the material at the proper-places.

' printing .or ornamenting of the same, which v. I will first describe the. means whereby I am enabled to intermittently feed the material from a continuous web or roll. The materlal Aris in the form of a roll A mounted upon a suitable support A2 arranged adja- .l

` bar B2 on which are adjustably mounted the auxiliary frames B3, B4. These frames carry in suitable bearings guide rollers b2, b3,

' may varyin details of construction according to the requirements of any particular case, but in the form illustrated there is a printing cylinder C and an im ression cylinder C mounted in a suitable rame C3 which is adjustable with relation tothe box-forming parts of the machine in any suitable way, and is shown asv having arms C4 adjustably secured to the main frame of the machine. Also mounted in the frame C3 is a suitable inking apparatus comprising among other things an ink applying roll C5 and proper ink supplying and distributing rollers, such, for instance, as are generally outlined in the drawing but need not be specifically described. Also mounted lin the .frame C3 are the rotary feed rollers D, D, and these feed rollers are connected to be driven in unison or harmony with the printing rollers C, C by any suitable means, such as indicated in the drawing, and are further to be driven in harmony with the other parts of the machine, as will appear hereafter.

As above indicated, it is desirable that the print-ing rollers should rotate lcontinuously inorder to .get effective distribution of the ink, land consequently the feed rollers D, D are driven continuously, and as the material is intermittently fed through the machine to receive the subsequent operations, some means must be provided to allow this to be done. In the present instance the printing cylinder C is of less diameter than the impression cylinder C, and mounted on the printing cylinder C is the printing form C? which extends around the surface of the printing cylinder to a greater or less extent accordin to the size of the articles to be produce or the extent of the printing upon said articles. Sometimes the printing is limited to the bodies of the boxes or receptacles, while again the end portions or the side portions, either or both, receive printing, and the size of the form CG varies accordingly. It is necessary, however, that the form should be less in circumference than the face of the printing cylinder so as to leave a blank space c on the surface of the cylinder between the ends of the form. It is of course necessary that the paper while being printed should be fed forward at a rate Aof speed corresponding with the travel of the printing surface, and consequently the feed rollers D, D are arranged to produce this feed. It is further necessary that the printing cylinders should make a complete rotation to each complete reciprocation of the other parts of the machine hereafter to be' described. In many instances it is desirable that the printing should commence at least, if not be completed, while the main body of the web is stationary, and this tendsv to buckle up or gather the web behind the feed rollers D, D. It is then desirable to take up this slack thus formed, and4 to ermit this to be done I construct the feed ro 1ers D, D, or one of them, wit-h cut-away portions, but preferably-it is onlyI necessary to cut away portions of the upper feed roller D, This feed roller is preferably made .up of disks set at different distances apart upon the shaft d,and they are provided with cutaway lportions d. These disksv can be adjusted onthe shaft so that the cut away por-l tions will overlap each other to a greater or less amount. The advantage of using disks isapparent, as they can be adjusted at different distances apartl so that in feeding the printed web they will not come in contact with the printed matter.

I will now describe briefly the operation of the parts so far described, and for 'this purpose will assume that the web A beyond dandy roll I; and th'encetends to unroll the 4 paper from the roll A. As soon as the paper passes the printing form C6 or the uncut-away portions of the feed roller D, the dandy roll b by its weight tends to draw back the slack, and as the inertia of the roll A may carry it beyond 'the distance necessary, the dandy roll b tends -to take up this sla-ck. In practice I nd that there is practically enough slack between the printing rolls and the roll of paper to supply material fortwo printings, although of course this may vary according to the relative tension of the parts and length used.` As a matter of fact the operations of thel whole machine are performed. with such rapidity that the roll-A may be said to be practically unwinding all'th'e time, andthe dandy roll b' may be saidv'to take up the unwound excess' or slack from the roll, while the dandy roll b mayy take up the slack drawn back through the printing and feeding rolls after the printing is d'one. The more nearly this stood. Connected to the main driving shaft, H is a crank disk H to which is connected v different relations to cutand score the blanklongitudinallyaccerding to the requirements ascesa idealoperation 'is attained, fthe more erfectl and satisfactoryitis. From this it. ollows that when the paper is gripped between the feeding rollers l), D to be fed forward and any suitable intermittently operatin means.

In the presentfinsta-nce I.' have indlcated a preferred operating means, such as is more fully disclosed and'claimed in my application Serial No. 296,305', led concurrently herewith, and so Iwill only briefly describe.

the same in this application, sufficiently enable the operations to be generally undera rack-bar H2 which operates in connection with. a pinion H3 loose on theshaft H4 'and having a suitable clutch'device whereby as the rack-bar moves rearward the` feed vrollers F, F are operated, vwhile when the rack-bar moves forward, the feed rollers remain stationary. v'lhe cutting and scoring devices are of a well-known type indicated in the drawings, and of course are adjustable in 4 of any particular case.

ln the present' instance,^"s,hown in Fig. 7, the` web is cut to trim the edges on the line's g and scoredA on the lines g. interposed between the. feed rollers F, 4F and the feed rollers D, DV is an adjusting device com'- prising'the roller E mounted in slotted bearings E' and capable of adjustment in those bearings by any suitable device, as ya ,hand wheel F2 and beveled gear connections v'with the bearings lof the roller E. The purposeof this arrangement will be apparent to those skilled in the art as it is well known that it is difficult to feed a continuous web by two diderent positively operating feed devices,

l order'that the parts shall properl intermittently operating on the web, and get perfect register unless means are provided so that each feed can practically act independently of the other, Moreover, in register, the distance between the feeding evices has to be accurately adjustedA 'under different circumstances, and the-purpose of the roller F,which is out of the line Alor path off-the web, is to lengthen or shorten the path of A the web so that the properpart of said web' d5? will be presented to the intermittently' box. 'It will be understoo cent ends of` thebox blanks,

operating operating the feed rollers D, D al certain amount of slack is produced in the webbehind the rollers, and in actual operation l prefer to adjustthe relations ofthe two .'sets' of feed rollers D ,lD and F, F. so that the latter shall commence to feed the materlal slightly after the feed rollersD, D have commenced to feed the same, so that when the feed Irollers F, F startto feed the webfeed rollers F, F and register be maintained. Again, as before seen, ur

therev will be no slip andF .it will have to move bodily but a small section or portion of the web in front of the feed rollers.

their feed, and when the' web 1s released .from the feed rollers D, D by coming opposite the cut-away portion d, the feed rollers F, F still continue to move a certain extent In' practice,l after the feed rollers have started in this way both setsof rollers D@ D and F,

operate concurrently for a portion of and act in opposition to the dandy roll b web stops moving it will be in 'proper registry both for the nextprinting operation and the lnext intermittent feeding operation.

lwhich tends to take up this slack, and by properly adjusting 'the roller E, when the.

The next operation upon vthe blank inlthe i machine illustrated consists in cutting the ends and sides to form the parts which are folded over or interlockednand vfastenedtogether .in making the box, an operation which is ordinarily termed'ldieing. 'l have shown at l aplaten moving on posts l and reciprocated by the connection l2 operated from suitable connections on the mainv shaft H. `This platen is arranged to `operate suitablegsupplementary dies which are inserted between the platen and the bed I3, and for the sake -of clearness inthis particular inl stance the dies are not shown, they being of any usual construction and'varying in their r contourac'cording to the particular partsto be cutor formedin makin any particular that these dies are operated while the blank is intermittently resting in its motion through the machine, and the-dies in this particular arianged to form the Haps i, z' on the adjaas shown'in Fig. 7. While this operation is being performed by the dies the preceding blanks are receiving lthe adhesive material'. `lhile various forinsof devices may -be used for applying the adhesive material, I- have instance are 11'5 y shown a vat J containing the material, in 'Y which'are Aarranged pins J', and these are1 arranged to be lifted by a-rodJ2 operated in the present instance byl a lever J3 connected with the laten 'I and moving con lcurrently therewith.'v In this way the adhesive material is lifted upf'on the ends of the pins J and 4impressed upon the under side of the blanks-at the proper positions.

rollers K, K in suitable bearings on the frame of the machine, and these feed rollers lare preferably driven Vby positive gearing connected to the feed rollers F, F', and I have shown a sprocket chain K2 for this purpose, there being an adjustable idler roller K3 for taking up the slack of the chain. Also mounted on the shafts carrying the` fe'ed rollers K, K are the 'cutters L, L which operate to make the longitudinal cutZ between the two series of blanks. As these cutters are apt to depress one of the `cut edges andV raise the other out of the longitudinal plane through which the material passes, I provide guides L2, L3, the former` consisting of a, series of arms secured in the present instance to the bar L4, and the latter, La, being shown in the form of a plate secured to the bar L5, forming a passage through which the web moves. Mounted in the plate L3 are a series of pins or4 screws Z3 which can be adjusted so as to cause the adjacent cut edges of the web to again lie inthe longitudinal plane through which it passes, so that the materiall will be practically at as it passes to the cutters hereafter to bel described. The s litted web is fed along for the next series of operations,

' which consist in forming the box or tray and severing the blanks therefor from the longitudinal web. In the present instance I have' shown an improved mechanismfor accomplishing these results which I will now describe. Mounted on the mainframe of the machine is an auxiliary frame M shown in the 'form of a cast iron bed, ythe upwardly projecting'endportions being further secured by the stay barsor connecting rods M. Adjustably mounted in theauxiliary bed M is a die iece N having openings N to'receive the p ungers-and boxes hereafter described. These openings N', two being shown in the present instance, have'three sides formed in the die piece N, vthe other side being movable and shown as a transverse bar or lplate N2, and this-bar N2 is mounted on pins N3 secured to the body N. The movable side N2 can be operated by any suitable means, and as shown I have provided toggle levers N4-connected to the side N2' and to adjustable bearings Ni in therear end M2 of the auxiliary bed. These toggles are operated by a cam N6 on a shaft N7 driven in ja manner hereafter described to move the side N2 to and from the die piece N for the pur ose hereinafter stated. Thus the die piece constitute the female dies in which the1 boxes are formed, and I prefer to bevel or chamfer the top edges of the dies adjacent the openings, as at n, and further I mount in recesses and movable piece or bar'NZ in these dies spring arms n having projecting flanges n2 on the two opposite sides of the die, the purpose of` which will appear later.

v The 'die piece N is adjustably mounted in the auxiliary frame M and may be adjusted therein in any suitable way, as by means of the screws M3. Cooperating with these dies N are the plungers il) which are mounted in a cross piece P su ported by the uprights P2 secured to the m 1n frame. These plungers are reciprocated to lperformther function in a peculiar way and by the mechanism which I will nowdescribe. The unsevered blanks to form the trays are fed Yover the openings in the die piece N in proper relations thereto, and when the plunger operates it is first moved downward sufficiently to engage the -blanks land lightly hold them in their proper places while the blanks are severed from the web by the cutters O, O. The next operation of the plungers -forces the blanks into the dies `N and forms the trays, and in order to facilitate this operation and cause the parts to fold in properly, I provide blocksA n3 at each of the corners and these are preferably adjustably mounted on the -die piece Ny and` the bar N2 as shown. The function of these blocks is to insure the inward folding of the lends of the lap portions of the sides of the box against which the end portions of the box are folded, and the beveled edges n* on the sides of the openings are preferablyslightly less in extent than the beveled portions n on the ends, so that the side portions of the box blank will first be turned up before the end portions of the box are turned up as the blank-is forced into the die. This is of particular advantage to prevent any wearing or rubbing of the adhesive material, it being desirable to have the sides and the lap portions thereof folded into their normal positions slightly brought into their normal positions, and then they are pressed directly against the adhesive material without previously rubbinggor disturbing it. 'When the' plunger reaches its lowest position and the box has 'been folded in the manner just described,

.before the end portions of the box are pressure on the ends of the box While held by the plunger inthe die N, and in this wa I am enabled to give a very heavy pressury to those pbrtions of the box to which the adhesive is applied and insure the parts ad- `herin .As but one side of the die moves,

that 1s, the bar N2, in order to get an even pressure upon both ends of the boxv the plun- 'f ger is arranged so that it can move longitudinally in the die, and to permlt this moveeeaoae ment I provide a spring bearing P3 con- 'nection with the support .P,'which'allows the plunger to move forward slightly while in the die. ',When this is accomplished'the. toggles are loosened and the bar N2 moves backward; the plungers rise to the full eX- tent of `their upward movement and are held inl-this position, and the springs u grasp the box and strip it from` the plunger as it moves upward. While this operation of folding and securing the parts of the box has been taking lace, the blanks are severed by the cutters 0 these operate after the first downward movementof the plungers while the material is grasped between the plungers and dies.`

While different forms of cutters may be used, l have shown a ,well known form ofshear cutters which are normally held open by a spring o on a guide pin 0 at each end, and the upper cutter is moved downward at the proper time to sever the blanks. `'In this instance l have shown pivotally mounted on the uprights P2, levers G2 which rest uponthe upper cutter bar 0', and these levers O2 preferably have friction wheels o2 against which 'the cams O3 impinge, they being mounted on a shaft O4 operated by a sprocket chain. @so as to depress th'e cutters quickly and sever the blanks at the proper time. While different means may be used to operate the plungers, l have shown a preferred -construction whichaccomplishes the results satisfactorily. In order to facilitate the operation of the plungers'they are counterbalanced, and l have shown weights@ c'onnected by suitable connections, asa chain Q passing over the sheave Q2, and thesecourn terweights are guided by the pins or rods@3 in brackets Q4- and are preferably provided with take-up springs Q6, i

The plungers P are provided at their 'upv-I per ends with a cross-slotted bearing P4 inv which operates a crank pin R onthe Icrank wheel lt suitably supported in the uprights P2. These crank wheels are driven by gears R2 on a shaft R3,on which shaft is mounted,

the variable stop motion for producing the different movements of the plungers, as heretofore described. y V r The variablev stop -motion consists of a disk S fast on the shaft R3, and this is provided with a dog s projecting beyond its periphery and normally forced outward by a spring a. vLoosely mounted on the shaftl is the'caphpiece S', the innerperiphery of l which is provided with a series of notches s2 adapted to -be engaged by the dog s.

Mounted on the hubof this cap-piece and,v secured thereto is a sprocket wheel .S2 which is driven by a` suitable sprocket chain Ss -so that it rotates continuously and carries with it the ca S.. Slidably mounted upon the shaft R3 1s a clutch portion S4L having a disk and,as before intimated,

I S5 provided with a series of pins for pro jections 85 according to the number of stops desired in connection with the plungers.v

These pins a5 can be variably spaced on the disk S5. This clutch portion S-4 is-moved longitudinallywon the shaft R3 under the stress of aspringit7 and is moved'in the opposits direction by the lever T connected to a rod Ton the uprights P2, the other end ertending` into positionl to be operated by lugs tron a disk T2 mounted on a sleeve T3 rotating upon 'a stud T4 land Ycarrying a sprocket .wheel T5 connected to be driven Vby the sprocket chain S3 so asvto move im' unison with the other portions of the stop motion. The lugs. t are'adjustably mounted in the disk T2and there may be any desired number of them corresponding to the number of stops desired. The cap-'piece S, whileloosely mounted on the shaft R3, is under the stress of a friction device shown as the lock nuts-S8 'with aA suitable washer or friction gasket between.' them' and the cap-piece, so that there is more or less friction between the parts and suiiicient to tend to rotate the shaft to carrythe dog beyond -the stop pin a5 after it has been knocked out of engagement by saidpin. Y

Itwill now be seen thatfwhen the parts are in their normal position the dog engages the notches s2 and the shaftS3 is rotating, but when the dogreaches one of the pins a5 it. isfkno'cked outfof engagement with the tooth s2 andthe shaft R3 immediately stops in this condition until, through the medium of a lug t, the lever T moves the clutch portion vS4 longitudinally on the shaft'R's, so as to withdraw the pin S5 out' ofthe path of the dog s, when it immediately again engages the tooth a2 and the shaft is rotated until the-dog reaches another pin S5, when the operations are repeated. llt will thus be seen" that'lby properly positioning the pinsand the lugsv t, any desired number `of'stops or spaces of time between vthe stops canjbe obtained. In order to drive these various parts of the die and plunger, l provide a cut sprocket chain connected to the mainl shaft and-sprocket wheel on the shaft ll, and from this shaft are driven the' cam ous operation, and the various devices can :be adjusted with relation to each other to 3.25 tached under heavy pressure in'one continumake boxes or receptacles of different sizes and characteristics and so as to produce practically perfect registry throughout `all the operations. t
