PAPER-BOX MACHINE.

Patented Aug'. 6, 1907.

Application filed January 3, 1902. Serial No. 88.327.

To all whom it may concern:

Be it known that I, IRA W. HOLLETT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Paper-Box Machines, of which the following is a description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates more particularly to paper box machines in which the properly creased blank for the box to be formed is automatically folded into collapsed or flat box form and the opposite edges of the blank pasted together to form an open ended tube which is delivered from the machine in collapsed or flat form, and is rectangular in cross section when opened out into box form.

My invention has for its object, the simplification and increased eciency of the automatic folding and pasting mechanism making up the machine, and lits novelty consists in certain new constructions, arrangements, combinations and modes of operation of the parts employed, which will be hereinafter more fully explained and particularly set forth in the claims.

In the accompanying drawings, Figure 1, represents a top plan view of the machine, with the supporting frame that projects vertically above the bed of the machine cut away to better expose the parts beneath; Fig. 2, a side elevation of the machine, with said frame shown in position; Fig 3 a perspective view of the folding and pasting mechanism of the machine showing the folding operations of several paper blanks going therethrough; Fig. 3 a detail of one of the box blanks for whose folding the machine is here shown adjusted;

upon a larger scale; Figs. 5 and 6 vertical cross sections upon lines 5 5 and 6-6 respectively of Fig. 1 Fig. 7y

a horizontal plan view of the parts beneath the bed or table of the machine, showing the lower set of feed rollers and the driving gearing therefor and also showing the means for adjusting the strips H; Fig. 8 a side elevation of the driving gearing shown in Fig. 7; Fig. 9 a longitudinal vertical section through the bed of the machine adjacent the train of feed rollers taken on line 9 of Fig. 4 and showing such feed rollers; Figs. 10, 11, 12 and 13 details of the upper train of feed rollers, Fig. 1l being a section on line 1l of Fig. 10 and Fig. 14 a section on line 14 of Fig. 13; Figs. 15 and 16 detail views of the gluing mechanism; Fig. 17 a section of one of the feed rollers V/ and Figs. 18, *19 and 20 detail views showing a modified construction of feed devices.

The working parts of the machine are mounted on a main frame A supported on the legs a and having at its left hand end, Fig; l, upwardly extending plates or flanges A in which are journaled the train or series of transversely arranged pressure rollers B. Extending to the right from said train of rollers is the bed or table of the machine, comprising, in the present instance, the pair of longitudinal rails or bars C, the two cross bars D and E; the thin longitudinal metal strips F adjustably secured to said cross bars and movable in unison towards or away from eachother in a manner and for a purpose hereinafter more particularly des'cribed. The rails or'bars C are supported by and secured to the machine frame, as clearly illustrated in Figs.`3, 5 and G, While the cross bars D and E which are each provided with the slots d are let into the 1ongitudinal rails C and fastened thereto by screws c, Fig. 7, or otherwise. At the rear of the machine and adjacent the pressure rollers a third cross bar a/ is provided which cross bar is here shown as a separate part ofthe frame A and in the top of which a` slot dis formed similar to the slots in the cross bars D and E.

The strips F which may be said to form the table on which the box blanks slide in their progress through the machine are arranged to slide transversely of the machine along the cross bars and in such a manner that they will approach or recede from each other in unison without disturbing their parallelism. To this end each strip F is fastened by screws or otherwise to T shaped blocks f movable in the slots d which are correspondingly T shaped to receive them. Each strip is also fastened to the horizontal portion or limb of L shaped blocks F/ as shown more particularly in Figs. 5 and 7, and for the purpose of having the blocks and consequently their strips move towards and away from each other suitable mechanism is employed such as the two transverse screws G which are journaled near their ends in the rails or bars C and are provided with the right and left screw threads g and g which respectively engage the vertical portions or limbs of the L shaped blocks F. Each screw has on one end a bevel gear g2 adapted to mesh with a bevel gear h secured to the ends of a shaft II extending longitudinally of the machine as best seen in Figs. l, 2, 3 und 7, such shaft being suitably mounted, in the present instance in the bearing brackets 01 supports II securcd to the ledge or flange h of the. main frame 1 3. One of the screws G is provided with the hand wheel G by turning which both screws` are rotated in the saine direction through the gears andshaft just described, with the result that the strips F will be adjusted transversely of the machine towards or away from each other according to the direction of rotation, whereby such strips are capable of accommodating different widths of box blanks having different scoring. It will be understood that the strips F are also secured to blocks f adapted to slide in the slot .formed by the cross bar a adjacent the pressure rollers. Beginning` in the present instance at a point near the cross bar D and extending towards and substantially to the pressure rollers, an abutment is formed on each strip F such abutment here comprising an angle plate or guide F2 secured to the strip and extending longitudinally thereof, Figs. 3, 4 and 6, as will be understood from an examination of Fig. 3. The distance between these abutments or angle plates F2 represents the width of the folded box in its flat form as completed by the machine. I

Secured at their opposite ends to the cross bars D, E, at the extreme opposite sides of the machine are two angle plates or horizontal strips or guides l, having upturned iianges at their outer edges, and constituting guide ways for the outer edges of the blanks when first put on the machine, that is the unfolded blanks, Fig. 3. These angle plates are adjustable transversely of the machine, along the cross bars, the same as the strips F but not by the same means, screws i here clamping the guides to the block i in the slots of the cross bars, Fig. 6.

Arranged longitudinally beneath the hori7iontal bed or table of the machine, near its middle line, is a train v of feed rollers J ,y Figs. 7 and 8 fast upon transverse shafts journaled at their opposite ends in bearings in the longitudinal rails or bars C of the frame work of the machine and projecting beyond the left hand one of said bars and having fast upon their projecting ends bevel gears orpinions j meshing with corresponding gears k upon a shaft K driven at its forward end by a shaft K. This shaft K is geared to the main driving shaft K2 of the machine by gearing shown in Figs. l ,and 2 and the shaft K2 has' mounted upon its opposite end a tight pulley lc and loose pulley k2 over which the driving belt passes, and is shifted from one to the other by a shifter L operated by a transversely sliding bar l guidedk by slots and bolts upon the top of the yframe work in which the feed rollers B are journaled. A lever l is connected at its front end to a shifter bart and extends rearward to the rear of the machine,

within convenient reach of the operator engaged in feeding the blanks to the machine, so that he may readily stop and start the machine at will.

Supported at their lower ends upon the cross bars D and E of the machine are two vertical rectangular yoke frames Figs. 1, 2, 3 and 5, which serve to support, at some distance above the bed or table of the machine, a bar N extending longitudinally of the machine, Figs. l., 3 and 4. Depending from and vertically adjustable in said bar N are two rods N which carry at their lower ends a sort of trough O, Figs. 1, 3, 4, 5, 6 and l2,` 13 and 14. I The function `of this trough is to support the inner pair of folders above the bed or table of the machine, as hereinafter described, and also to form a support and bearing for a train of feed rollers O immediately above and in line with the feed rollers J. It is rectangular in cross section, with an open top,y and its bottom is provided with openings immediately beneath 'the rollers O to permit the latter to extend o, Figs. 3, 9, and 14 extending longitudinally of theA trough immediately within its side walls. These wires are secured to the trough at their opposite ends and intermediate the rollers O they pass beneath cross rods o secured in the trough, which hold the wires down against the spindles of the rollers O. The trough O while supported entirely by the rods N depending from the yoke frames M extends forward of said rods nearly to the train of pressure rollers B and carries the series of feed rollers O to vcoperate with each one of the rollers J. The last roller O2 in the train is carried by a yoke o2 secured to the front end of the trough, Fig. 1, instead of being journaled in the side walls ofthe trough as are the other rollers.

A paste or glue box P is suitably supported beneath the right side of the machine, near its rear end, Figs.- l, 2 and 5, and the glue roll P turning at its lower edge in the same, and coperating therewith, projects at its upper edge through a slot in the right hand guide or angle plate I of the table, into position to coperate with a feed and pressure roller l2 suitably mounted upon the table. j

For the purpose of properly folding the box blank in its travel. through the machine, it is caused to enL counter certain rods Q, Q, hereinafter referred to as the folder rods. There are two of these rods, which, in the present instance, are each formed of two telescoping sections, one of which sections is a pipe or tube q2, and, as will'be understood, the folder rods are correspondingly adjusted at their supported ends.

The outer ends of the folder rods are capable, in the of the following construction and arrangement; a horizontal rod R is secured to each strip F, Fig. 3 by means of the angle plates r, which, in fact, rest upon thel abutment plates or guides F2. losts S are clamped at their lower ends to the rods R in such manner that` the posts may be adjusted longitudinally as well as rotarily thereon. lhe posts also carry a support S adapted to swivel thereon and to be clamped thereto and also to be moved or adjusted up or down, that. is longitudinally of the posts.

Mounted to 'move longi-` '105 present instance, of a universal adjustment by meansl tudinally of and to swivel on the supports S are rods i s which are pivotally connected at one end to the folder rods Q, Q Fig. l.. By this means, all the necessary adjustments of the folder rods are obtainable, it being understood that the folder rods are adapted to e adjusted independently and in different mannerlwith respect to each other in order that one part of thelbox blank may be folded in advance of another part as will hereinafter be made apparent. The rods R also carry posts T similar to the other posts and also provide with the supports T in which are 'adjustably mounted` the bent or curved pressure rods T2 which are capable of universal adjustment and Whose function is to press upon the folded sides of the box blank just before it is upon the folded blank. The blanks are then inserted delivered to the pressure rollers. Cooperating withv the curved folder rods Q, Q, in this folding of the blank are two folder plates U U Figs. 1, 3, 4, 5 and 6. These folder plates extend substantially full length of the trough O upon opposite sides of the same, and are supported therefrom, near their middle and at their rear ends, by horizontal rods u there being two of said rods projecting inward from each folder plate and passing through horizontal apertures in the side walls of the trough. The rods u in the present instance pass through the'trough and below a block u on the trough and are secured in their different adjusted positions therein by means of set screws u2, Figs. 1, 3, Lland 9. -This connection of the folder plates with the trough O serves to support them immediately above the horizontal bed/of the machine formed of the Astrips F so as to permit free passage of the paper blanks beneath them, and at the same time permits them to be adjusted j laterally to coperatei with Iblanks of different widths and differently scored for boxes of varying proportions.

The rear half or portion of each of the folder plates is inclined upward and inward at an angle approximating forty five degrees, Fig. 5, but about midway of its length each plate is bent over and inward and downward into a horizontal plane, Fig. 1, 4 and 6 and4 lies immediately beneath the superposed folder rods.

Y In Fig. 3al there is shown one of the paper blanks which the machine is designed and here shown adjusted to fold and secure in box form, said blank being composed of longitudinal side walls 1, 2, 3, 4, and a pasting flap 5, separated by scoring along the lines indicated and also composed of the usual end iiaps projecting from the opposite ends of said side walls which flaps, however, are not folded by the machine. The box resulting from the blank herein shown is a rectangular box. To accommodate and properly fold into box form, the box blank herein shown', the abutments or guide plates I have been adjusted to such a distance from each other transversely of the machine that the opposite edges of the blank pass freely but somewhat closely between them which causes the glue iiap 5 upon the right handwedge of the blank to pass between the glue roll and the superposed feed and pressure roller P2 and thertry cause glue to be applied to the under side of said flap. Likewise by turning the hand wheel G in the proper direction the two strips F are moved in unison towards or away from each other so that the distance between the angle plates F2 which they carry will represent the width of the box when in folded or collapsed form. Also the folder rods Q, Q are properly adjusted in such manner that the side 4 of the box which carries the glued flap 5 will be folded down in advance so that the side 1 to be superposed will be folded down on top of the pasted side of the glued flap. The folder plates are adjusted by hand so that their outer edges vtill approximately register with or overlie the score lines between the sides 1 2 and of the box blank. Furthermore the presser rods T2 are adjusted so as to press with the proper pressure andat the proper-place one by one and pushed rearward by hand until the flap 5 of the box blank is engaged by the glue roll and its cooperating pressure roller and the body of the blank passes beneath the rear end of the trough and is engaged by the rearmost pair of feed rollers .T and O, whereupon the blank will be carried on further through the machine by the successive pairs of feed rollers. The perspective of the machine, Fig. 3, shows a series of four box blanks passing .through the machine, following each other closely 'as in actual practice, and in different stages of formation or folding. The first blank shown at the right hand end of Fig. 3 has already rece/ived glue from the glue roller and has been advanced by the series of feed rollers sufficiently far to have its sides 1 and 4 encounter the folder rods Q, Q which bend its'said sides 1 4 upwardly as Ishown by the first blank in said perspective. As the blank progresses further in its passage through the machine, the folder rods continue to fold the sides 1 4 as shown by the second blank in said perspective and such folding is continued as the -blank passes on through the machine until the sides 1 4 are bent to a substantially horizontal position, the

side 4 however, being folded or bent downwards in advance of the side 1 so that the glued side of the iiap is presented upwardly and the side l superposed. The folder plates U, U which have been adjusted so as to approximately register with or overlie the scored lines separating the sides 1 2 and 3 4 of the blank insure the proper bending of the blank along said score lines, the blank being folded over until .the folder plates are embraced between the sides 1 2 and 3 4 respectively. The blank now passes on rearward beneath the presser rods and is carried to a position to be gripped between a cylindrical roller V and a superposed pair of feed rollers V mounted on a shaft V2 driven by the driving shaft, Fig. 1, and preferably provided with a rubber face so as to properly grip and draw the blank rearwardly. Bypreference the shaft V2 is arranged to yield vertically in suitable journal boxes and is normally pressed downwardly by suitable tension, Fig. 10, and its rollers are adjustable longitudinally thereon, Fig. 17, through the provision of the key o and tightening set screw fu. These rllers V deliver the blank to the train of pressure rollers B by which it is pressed into flat form and the edge of the sid-e 1 firmly secured to the flap 5 and from which the blank is delivered in completed form upon any suitable support or table which may be provided at the rear of the machine to receive the completed or folded blanks.

As hereinbefore described, the glue wheel is adjustable with the right hand guide or plate I which it passes. As illustrated `in Figs. 5, 15 and 16, the glue feed' roller P which dips into the glue is rotated by the last shaft j at the front of the machine which shaft'is extended for this purpose further than the others. This extended shaft is slightly flattened on one side and the feed roller P vis shaped to fitthereon in such manner as to slide freely longitudinally on such shaft when the guide I is adjusted, and to be rotated by such shaft. Mounted on i the cross piece E by means of the bolt e is a bracket E into which is dovetailed a scraper arm E2' forked at its forward end to embrace the glue roller P, Figs. 5,"15 and 16. When the bolt e is loosened the scraper'arnl may be adjusted by the set screw e either forwardly or backwardlyl longitudinally of the machine. As shown inA Figs. 15 and 16 a scraper blade E3 is dovetailed into one of the forks of the arm E2 and adjusted towards and l away from the roller P by a set screw e2. The glue roller P2 is mounted to rotate on a horizontal shaft p passing through and adjustable laterally on a vertical post p which is adjustable vertically ina lug p2 on the guide I. vBy these means the glue wheel P2 may be adjusted laterally together with the guide I and also adjusted vertically. I

It will be understoodthat the supporting posts of the trough O and the folder plat/es U, U/ carried by such trough do not interfere with or obstruct the passage of the blanks through the machine, since the sides 1 4 of the blanks are not bent over or inward to horizontal position until after they have passed rearward of the rear one N of said posts. Furthermore their supporting or depending posts are adjustable independently in such manner that 'the trough or feed roller frame which they The variety and character of the described adjustments in mymachine are desirable owing to the different sizes and scoring of the blanks as well as the different kind and weights ofpaper of th blanks. The adjustment of the guides I l is determined by the width of the unfolded blank and that of the guides F2 by the width of the folded blank. The rapidity of the folding of the opposite sides of the blank is determined by the i particular adjustment of the folder rods Q Q and the same is true of their relative folding, one in the advance of the other. So also thepresser rods T2 are adjusted longitudinally for the different lengths of box, being moved 'rearwardly for long boxes and are adjusted axially for different widths of box or blank. The action of stock of different size, weight and character differ so much that no particular adjustment can be specified I but the parts are adjusted by trial until the blanks pass through their operations with the perfection and smoothness. v

My improved machine in the form above described is designed to accommodate the ordinary sized blanks, but when it is desired to employ the machine for folding very small blanks such as cigarette box blanks, ,I substitute for the lower train of feed rollers .I an endless feed belt W passing over driving rollersW suitably located in the machine, and traveling at itsupper side upon a table W2 between said rollers, Figs. 18, 19 and 20; and for the upper train of rollers carried bythe trough O I substitute the tra/in of rollers X bearing upon `the belt W as it passes over the table W2, the latter being provided with a groove to receive said belt, so that the upper surface of the latter will be flush with the' upper surface of the table, as shown in Fig. 20. The rollers X are mounted upon spindles X secured at their outer i ends to and vertically adjustable in-brackets X2 seaccomplished with a feed mechanism composed simply of two trains ofrollors as in the principal construction which I have described.

Suitable locking means may be provided for the hand wheel G in order that the proper adjustment mayr be maintained against accidental displacement or tampering and in the present instance I have shown a clamp lcomprising a clamping plate G2 secured to the bracket H and embracing the screw G and adapted to be clamped thereto by the screw G3. i
