PATENT PAPER-BOX MACHINE.

SPECIFICATION forming part of Letters Patent No. 352,304, dated November 9, 1886.

Application filed November 12, 1885. Serial No. 182,513. (No model.) I

To all wiwm it may concern:

Be it known that l, WALTER S. DAVIS, a citizen of the United States, residing at Contoocook, in the county of Merrimack and Slate of New Hampshire, have invented certain new and useful Improvements in Paper-Box Machines, of which the following is a specification.

My invention relates to machines for making paper boxes of various dimensions, the object of my invention being to provide in a machine mechanism by which boxes may be formed (exceptingthe cover) entire from three pieces of card or straw board, which are previously cut the proper dimensions to form a box of a given size and placed in their re spective receptacles, from which they may be delivered formed into boxes, pastedtogether, and carried singly from the machine by the said niechanisin with great rapidity.

My invention consists in the combination of the various mechanisms necessary for carrying the different parts from which a box is to be formed to their proper place, forming and pasting the said parts together and depositing the completed box upon a suitable carrier or carriage, by which said box may be removed from the machine, all of which will be clearly described in the following specification, and illustrated in the accompanying drawings, forming part thereof.

Figure 1 represents an end elevation of my improved machine, Fig. 2 being the rear side elevation. Fig. 3 is a vertical {section taken centrally from front to back of the machine, and showing one of the card board receivers partially filled. with those parts which form the body of a box and the reciprocal and rotat-ive mechanism. The parts are carried singly from said receiver to their proper po sition under the plunger or former. Fig. 4 is I an end sectional elevation, which better illustrates the actuating mechanism applied to those three feed-rolls which are shown in Fig. 3 as mounted upon the end frames, and their rigid connections. Fig. 5 is asectional plan view of a portion of the frame of the machine, the adjustable tables between which a box is formed, the screw-rods and gearing by which said tables are operated, and the feed-rolls which were shown in Fig. 4. Figs. 6 and 7 table.

are respectively a side elevation and plan view of the sliding blocks, adapted to movein grooves formed in the adjustable tables, and

to carry the adjustable stops provided thereon 5 5 for preventing those parts which form the body of a box from moving beyond the re quired limit under the former. Fig. 8 is a plan view of a crossframe which carries an adjustable bed-table, an adjustable table upon 6c which the receivers for those parts composing the ends of a box are secured, and a slide for carrying said parts to their destination, ready to be pasted to the body of a box. Fig. 9 is a cross-section of all above line Y Y, Fig. 8. Fig. 10 is a sectional view showing the former in a position to form a box, one of the pasterolls in readiness to apply paste as it passes down, the card-boards which are to form the ends of a box in their proper position relative to the said former, and also the adj ustablebed- Fig. 11 is an enlarged sectional view showing the paste boxes and rolls in end elevation and the mechanism by. which they are drawn toward a box in order to place a layer of paste thereon. Fig. 12 is a cross-section of one of the paste-boxes, showing the manner of mounting the roll therein. Fig. 13 is a plan view of the sliding bed-table. Fig.

14 is a plan view of a slide which forms an important part of the mechanism for depositing the ends of a box in their proper position. Fig. 15 is a longitudinal sectional elevation of the frame shown in plan, Fig. 8 having the parts shown in Figs. 13 and 14: in their respective positions and also in section. Fig. 16 isa cross-section of one of the adjustable tables having the stop, against which the heads or ends of a box are thrust, hinged thereto. Fig. 17 is an elevation showing both go chutes from which the ends of a box are fed out, Fig. 18-being a plan view of same. Fig.

19 is a general plan of thetable upon which the aforesaid chutes are adj ustably secured. Fig.

20 represents anedge view of the same. Fig. 21 is a sectional elevation showing the manner of securing the chutes upon the table seen in Fig.

20. Fig. 22 is an elevation of one of the chutes having in its proper position the slide by Which the ends of a box are delivered singly therefrom. Fig. 23 is a plan view of the same, showing the slidein the act of deliveringan 7 end of a box.

Fig. 24 is an enlarged elevation of one of the pressure-plates by which the ends of a box are stuck to the body thereof, conneeted to a section of the lever by which it is operated. Fig. 25 is a section of one of said levers, having connected to its lower end the actuating mechanism, consisting of a cam and horizontal levers. Fig. 26 is a plan view of a portion of the actuating mechanism for said vertical levers, showing sections of that portion of the frame of the machine upon which said mechanism is mounted. Fig. 27 is an en- .larged elevation of one of the bevel-gears and pinion by which the vertical shafts driving the parts show n'in Figs. 13 and 14 are operated. Figs. 28 and 29 are respectively an elevation and plan view of either of the slotted arms which are mounted upon the top of said vertical shafts, and which are connected by suitablesliding blocks to the slots shown in thesaid parts Figs. 13 and 14. Fig. 30 illustrates one manner of constructing an adjustable former. (Shownin elevation.) Fig. 31 is a plan view of same. Fig.32 is a perspective view of a partly-completed box.

Like reference-letters indicate corresponding parts throughout the various views.

The frame may be of any convenient design, and consists of suitable uprights, A A, and various connecting parts, to be mentioned as opportunity offers in the following description. The pieces of card-board which form the bottom and sides of a box, after being cut to certain dimensions, are first placed in the receptacle B, which is located at the back of the machine, from which they are fed out through slot b at the bottom of the pile, singly, toward and between the feed-rolls-O O, the mechanism by which this movement is obtained consisting of a serrated rack or frame, B, and suitable means by which it may have a reciprocating motion to and away from the feed-rolls O G, a convenient method for accomplishing this being shown best in Fig. 3 of the accompanying drawings, in which b is a block connected at its top to a portion of the frame B, its bottom being swiveled' to a slide, D, the outer end of which is connected by swivel to a lever, E, fulerumed about midway from either end thereof to the under side of one of the parts a of the frame, as at E. In order to transmit a rocking motion to the opposite end of said lever, said end is slotted lengthwise, said slot being long enough to afford suflicient play to a bolt, 0, or other suitable connection, which passes through the slotted end of said lever, and the free end of an arm, F, which is revolved horizontally by a system of bevelgearing andshafts connecting with the counter-shaft G. If desired, the arm F may be constructed with a slot for rendering its connection with the lever E adjustable, and thus givin g a varied stroke to the feeding serrated frame B. This receptacle B may be made in some approved adjustable form relative to its width andlength, in order that it may readily accommodate itself to the various dimensions of card-board required for different sizes of boxes; or different-sized receptacles'B may be provided for use, as required. The feed-rolls C C are mounted in bearings formed in either of the upright frames A A, suitable springs, 0 c, exerting a pressureupon thejournals of the roll 0 toward the roll 0. These are connected by spur-gears H H at one end, the roll 0 being provided outside of the spur-gear H witha bevel-pinion, I, meshing with the bevel-gear J, mounted on upper end of vertical shaft J, hung in suitable bearings and cdnnected at its lower terminus with the driving'shaft K by bevel gears j j, by which said feed-rolls receive their motion. When these pieces of card-board which form the bottom and sides ofa box shall have passed the feed-rolls G 0,

they enter between trucks L L, which carry them as far as the adjustable stop-pieces M, secured to the adjustable forming-tables N. The trucks L are one-half inch (more or less) in thickness and three inches (more or less) in diameter, and are mounted upon one end of either shaft 1 in suitable bearings, one of which is formed upon the under side of said tables N, and the other of which is provided upon either of the parts a of the frame, said trucks L projecting through slots n in either of the tables N, so that their periphery shall be one-quarter inch (more or less) above the upper surface of the said tables, as seen in the drawings.

The outer ends of either of the shafts l are provided with belt-pnlleys l, which are connected by belts with the pulleys 0 mounted near either end of the feed-roll G, as seen in full lines, Figs. 1 and 2, and dottedlines, Fig. 3, by which motion is communicated to the trucks L. The upper trucks, L, act merely as pressure-rolls to keep the card-board in contact with the trucks L, and they are designed to drop directly over the said trucks L, in order that their work may be the niost effective. The last-named rolls must of necessity'move with the adjustable forming-tables, which is provided for by splining the pulleys l to the shafts I, so as to admit of the necessary adjustment longitudinally of said shafts 1. Some provision must be made for a like adjustment of the trucks L, which will be hereinafter ex plained.

The tables N rest upon the parts a of the frame, and in order that they-may be adjusted relative to the width of box required to be made, between which tables said box must pass downward while being formed, said tables V are made somewhat longer than the distance from either outside edge of the parts a, and upon the under side 'of these projecting ends are formedlugs n,to which are threaded the screwrods 0, mounted ill bearings 0 near either end thereof and secured to the outside edge of either of the uprights A A, one of said rods with its bearings being shown in Fig. 2. The

lugs n on one of the tables N will be tapped by which it may be operated.

35 of the slides q.

5 direction the said tables may be moved apart,

and when rotated in the opposite direction they will be drawn toward each other. This is accomplished by a light horizontal shaft, P, mounted in bearings P, secured to the outside of the upright A, and provided with wormgears 19, meshing with spur gears 0, mounted on one end of either of the screw-rods O, as shownbest in Fig. 1. Said shaft P is also pro vided upon one end with a suitable crank, 19', When the said pieces of cardboard which form the bottom and sides of a boX shall have been deposited upon the forming-tables N in their proper position, they must be forced down between said 20 tables by a suitable die or former in order to bend up the sides thereof. This may consist of a rectangular wooden block or hollow iron or metal box, Q, of the proper dimensions, as seen best in Fig. 3; but in order to avoid the necessity of providing a separate plunger or former for the various sizes of boxes capable of being made by this machine I prefer the construction illustrated by Figs. and 31 of the drawings, in which the parts q q form a 30 cylindrical hub, the contacting surfaces of either of the parts q 9' being grooved for the reception, respectively, ofthe adjustable slides q" (1 which are placed as seen in Fig. 31, the slides q being above and resting upon the tops On the outer ends of either of the slides q" are hinged suitable right-angle pieces, q, their heights corresponding to that of the deepest box the machine is capable of making. The lower slides, q", are provided in like manner on either outer end with right-angle pieces g Thus to adjust said right-angle pieces q" to any given size of boxthe operator has simply to move them to or away from the parts q q and rotate the latter in opposite directions, when. the bolts g", which pass through the parts (1 q, may be tightened, the right-angle pieces (1 Q5 set, so that either their sides or ends respectively may be parallel, and the adjust-able die or former will be ready for use.

5 end of the bar R enters and is secured to a cross bar, It, by rivets or bolts 1', and the necessary vertical movementrequired by the die or fornr er Q, is communicated to the cross-bar It by the vertical bars S, located outside of either of 6a the uprights A A, the upper ends of which are pivoted to the ends of said bar R, their lower ends being connected to the bar S, pivoted to the uprights A A, for the purpose of maintaining the bars S as nearly as possiblein 6 a vertical position while moving up and down,

the pivot 8, connecting said bars S S, projecting far enough on the outside of the same'to carry the friction-rolls s, which enter camgrooves it. formed in the gear-wheels T, mounted upon either end of the counter-shaft G and meshing with the pinions Ir, mounted upon the driving-shaft K.

The cross-frame a is adapted to carry suitable sliding frames, U, fittedto ways formed thereon. Horizontal adjustable shafts'u, carrying the pressure-trucks L, are fitted in the lower end of said frames U, and by means of a set-screw, a, threaded to said frames and acting upon said shafts a, the operatoris enabled to adjust the trucks L relative to the trucks L, as previously mentioned. As the pieces of card-board upon which these trucks L L operate must be bent in order to form the sides and bottom of a box, it becomes necessary that the upper trucks, L, must be raised out of the way before the die or former Q operates upon said card-board.

Before describing the mechanism by which the said rolls are'raised it may be well tohere state thatt he peculiar form of the cam-grooves t in the gear-wheels T which in practice Ifind most preferable is such that while the said wheels T are making one quarter-revolution the die or former Q is detained at its highest elevation, the next quarter-revolntion bringing said die or former th ence downward to its lowest limit of movement, the next or third quarter-revolution detaining the said die in the last-named position, while the fourth quarterrevolution carries the said die back to the first-named position, or its highest limit ofmotion.

' The mechanism by which-the frames U, carrying the trucks L, are operated is dependent for its motion upon that of the bar R, carrying the die Q, and consists of the following parts:

A horizontal shaft. V, having bearings V secured upon one side of the cross-frame a is provided at either end with arms 1;, which pass thence through vertical slots or openings a", formed in the sliding frames U, and connect at their free ends with the bars WV, the other ends of said bars being pivoted, as at a to the said frames U, and midway from either end thereof with ashort arm, 12, adapted to be acted uponby the vertical bar r, bolted at its upper end to the rectangular bar R, as shown best in Fig. 3, in which View the die or former is shown at its highest point of stroke and the vertical bar'r resting upon the short lever 22. Now, with the downward movement of the former Q, the bar r, resting .u )on the lever i) must necessaril force the latter down also, thus raising the arms a, and, by reason of the connecting-levers W, the frames U to their upper limit of movement, as in Fig. 1, and this, too, before the said die or former Q shall have reached the formingtables N in its downward course, thus fulfilling for the. trucks L the necessary requirement before stated. By this means, also, the said trucks L are held in their elevated position until said die or former' during its upward stroke shall have passed the-said formingtable N.

Suitable slides, or, are secured to the forming-tables N, as shown in Figs. and 10, in such convenient manner as to render them capable of adjustment thereon relative to the required length of a box, for the purpose of bending over the ends of the bottom and sides of the same a half-inch, (more or less,) as shown in perspective view, Fig. 32, of that portion of a box upon which the ends may be pasted. In Fig. the die or former making its downwardstroke is shown to have reached a pointjust below the top surface of the forming-tables N a sufficient distance to have started the formation of the sides of a box,

. which are shown bent upward on about a forty-fivedegree angle. The ends of the bottom and sides of said box have also been partiall y bent over by contact with the slides a. As the die or former continues to move downward the bent ends, previously referred to, of the bottom and sides of the box are coated with paste by pasterolls X, said rolls being located directly underneath the forming tables N, one at either end of the die, and mounted in suitable paste-boxes, X, their frames :1: ex tending far enough at either end to rest and slide upon the parts a of the machine-frame. One side and top of the pasteboxes X are cut away, and the paste-rolls X so mounted therein as that while they are partially submerged in the paste their cylindrical surface will pro- 5 ject slightly beyond the side of the paste box,

as clearly shown in Fig. 12 of the drawings. Thus when said paste-boxes are moved to their operative position the paste-roll only comes in contact with the card-board box being formed. In order to bring said paste-rolls in contact with the box being formed only when said box is moving downward past said rolls, right-angled levers 1 are provided, which are ful'crumed at 2 to the uprights A A, as shown best in Fig. 11, their-short ends pivoted to suitable extension-rods, 3, by which the pasteboxes X may be adjusted relative to the required length of a box, the opposite ends of said extension -levers 3 being pivoted at a convenient point to the frames as of the pasteboxes, the longer end of said right angled levers 1 fitting slots formed in and near the top of vertical bars 4, having neartheir bottom suitable means for preventing any lateral movement of the same, as at 5, Fig. 11, and provided at their lower end with rolls 6, bearing upon cams 7, said cams being mounted upon the counter-shaft Gjust inside either of the uprights A A. One of the journals of either paste-roll X projects a trifle beyond the pastebox. Upon these are mounted chain-pulleys 8, which are driven by a suitable chain, 9,

passing under one and over the other of said.

pulleys, (so that they may be rotated in opposite directions,) andthence over pulleys 10, conveniently attached to either of the parts a of the frame, and under asimilar pulley, 11, mounted on driving-shaft K.

The card-board forming the ends of a box, after being cut the required size, is deposited in receptacles 12, consisting of plates 13, having vertical walls 14 15,-and adjustable wall 16, a tongue, 17, being formed at the bottom fitting groove 18, running longitudinally in the top surface of the table 19, upon which said plates 13 rest, and to which they are secured and rendered adjustable relative to the length of a given box by the screws 20, passing through the same and threaded to nuts 21, fitting slots 22, formed longitudinally in the said table 19.

In order to adjust the vertical walls 14 14.

relative to a 'box of given width, against one side of which the said walls'14 must be brought in contact, the table 19 is adjustably mounted upon the bed-frame 23by means of grooves 24, adapted to receive tongues 25, formed upon top of said bed-frame 23. The said table 19 is rendered capable of being fastened whereever required by a suitable screw, which may pass through slot 26, running transversely in said table, and be threaded to the bed-frame at 27.

The mechanism by which the pieces of cardboard forming the ends of a box are delivered from their receptacles 12 consists of the slides 28, having dovetailed tongues 29, fitting corresponding grooves, 30, formed in one side ofthe walls 15, as seen best in Figs. 17, 22, and 23, and having arms 31, the outer ends of which are mounted upon rods 32, rigidly secured to suitable stands, 33, mounted upon one end' of the adjustable slide 34, which moves in suitable ways, 35, formed upon the under side of the bed-frame 23, as in Fig. 15 of the drawings, said rods 32 being sutficiently long to admit of proper adjustment of the slides 28 relative to a box of given length by aid of the set-screws 36. The slides 28 occupy openings .left for the purpose between adjustable walls 16 and rigid walls 15 and a portion or section of the walls 14 and 15, as clearly seen in Figs. 17 and 18. That part of the slides 28 which carries the card-board out of the receptacles for a distance of slightly more than the length of the said cardboard is rabbeted on the side opposite to the tongues 29 to a depth of from one thirty-second to one-sixteenth of an inch, (more or less,) thus forming a shoulder, 23, as seen in Fig. 23, against and by means of which a piece of card-board may rest and be borne toward and to its destination, as also seen in Fig. 23; or these slides may readily be made adjustable relative to the required length of the card-board ends for a given box by mak ing said rabbetof greater length and inserting an adjustable plate of steel, 38, which may form the shoulder 23, the latter method (see Figs. 10, 15, and 28,) having secured l a layer of paste, as previously stated, by folwithin said slots 40 suitable connections; 41, which enter slots 42, formed in the-adjustable slides 34, and by which said slides 34 are given a reciprocal motion with the rotative motion of said arms, are mounted upon top of vertical shaft 43, carried in bearings 44 45, as seen in Fig 2, the lower end of said shaft being provided with the bevel'pinion 46, mesh ing with the bevel-gear segments 47, constructed as shown in detail, Fig. 27', their pitch diameters being four to one, or one to four, respeetively-i. 6., the larger gears '47 having just teeth enough to cause the pinion 46 to make one complete revolution, and this while the saidgear 47 is making butone quarter-revolution. By this arrangement the slides 28, after the gear 47 has been properly set on the counter-shaft G, are enabled to deliver the cardboard ends of a box to their proper position, and return to position shown in Fig. 2 before the forming-die Q, carrying the bottom and sides of a box, shall have reached in its downward course but little beyond the paste-rolls X, thus avoiding contact with the said delivery-slides, which would otherwise occur. To insure the perfect operation of these deliveryslides,.provision must be made whereby a certain amount of pressure is continuously applied to the card-board pieces contained in. the receptacles 12. This may be accomplished in various ways, one of these being shown in Figs. 22 and 23, in which a follower, 48, is placed in either .of the said receptacles, having an arm, 49, provided with a slot, 50, running lengthwise therewith, said arms extending beyond the openend of said receptacles and having connected to their outer ends a cord, 51, passing over grooved wheels 52, and thence downward through slot 50 of said arm 49, where they may be attached to suitable weights of proper power to supply the required pressure to the said follower-plates 48. Said wheels'52 are mounted upon rods 53, supported in bearings 54, secured to the said receptacles 12. To avoid any inaccuracy in depositing these card-board pieces contained in said receptacles, they are carried slightly beyond their proper position by the delivery-slides 28 and against the stopplate 55,. which is hinged, as seen in Fig. 16, to one of the forming-tables N, in such a position as thatit may hang a little off or away from the forming-die, except during the time the paste-rolls are distributing paste, as previously described, when, by reason of the connecting-rod 56, slide'bar 57 and a protuberance, 58, formed upon or attached to the vertical actuating-bar 4, said stop-plate is forced with the last of the upward and the first part of the downward motion of said bar4 into a vertical position, and thus places said card-board pieces so that their ends come exactly flush with the sides of the box, which by this time has reached the bed-table, to be hereinafter described. These card-board pieces are then pressed against those parts of the bottom and sides of the box which have received lower-plates 59, operated by the levers 60, fulcrumed at 61 to the uprights A A, their lower ends being connected by means of a forked link, 62, to a bar, 63, having in its opposite end a suitable stdd, 64, which may enter. a cam-groove, 65, formed for this purpose in the side of one of the wheels 66, both wheels 66 being mounted side by side upon the counter-shaft G, as seen in Figs. 2 and 26, each op erating one of the levers The bars 63 are carried in bearings 67, having caps 68, as shown, and rigidly fastened between parts a of the frame, which are connected at either end to the parts a.

The follower-plates 59 may be connected to the levers 60, with a view to the necessary adjustment required relative to the length of a given box, in a simple 1nanner,-as seen in detail, Fig. 24. To the outside of the said follower-plates is hinged one end of a rod, to which is threaded a collar and two check-nuts, one at either end of said collar, said collar being connected to the upper end' of said lever 60, as shown.

The levers 60 are composed of a framework, which affords the opening 69, as seen in Fig. 2, the obj ectof which is to provide a passage for a wide belt, upon which the boxes as completed maybe carried away from the machine. This is rendered possible by the movement of the bed-table 70, which is carried uponways 25, formed upon the bed-frame 23, and is provided with aslot, 71, running transversely therein. A suitable arm, 7 2, of the same construction as the arm 39, being likewise slotted and connected at 73.to the slot 71 insaid bedtable, is mounted upon the vertical shaft 74, carried in bearings 75 76, and provided at its lower end with a bevel-pinion, 77, meshing with a bevelgear segment, 78, mounted upon the counter-shaft G. In this manner a reciprocal motion is communicated to the'said bedtable 70, and its forward and return movement is made while the counter-shaft G is making one quarter-revolution in the same manner as does the slide 34, the pinion 77 and gear-wheel 78 being made from the same pattern from which the pinion and gear 46 47 are made. The moment the pressure plates 59 shall have pressed the heads onto the box they plate 55 also eased off, as seen in Fig. 10, and the bed-table 70 removed from under the forming-die Q, the completed box thereupon dropping through the bedframe 23 between the slideways 25 and upon a carrier-belt, as previousl y stated, or other suitable means for removing the said boxes from said machine.

The sliding nuts M are providedfor the adjustable guide-stops M, the slots in said parts M fitting the rectangular part at of the nuts. A thumb-nut, m, being threaded to thestud m which, by aid of the flange m projecting from said nut on the under side of the slot 12.

IIC

are both simultaneously removed, the stopformed in the forming-tables N, said guide-stop M is held in any position desired.
