GUSTAV L. JAFGER, OF NEW YORK, N. Y.

PAPER-BOX MACHINE.

SPECIFICATION forming part of Lettexs Patent No. 372,624, dated November 1, 1887.

(No model.)

To all whom, it may concern.-

Be it known that I, Gnsrav L. J anenn, a citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in PaperBox Machines, of which the following is a specification.

My invention relates to improvements in paper-box machines of that class in which the blank is fed, cut, creased, and folded, respectively, by feed-rolls, rotary cutter-rolls, and hinged wings, such, for instance, as illustrated in a patent granted to me February 25, 1873,

The object of my present invention is to provide a machine fitted for the manufacture of boxes of various sizes, which object I accomplish bya novel construction and arrangement of operating parts, all such parts being either adjustable or exchangeable.

The peculiar features in the construction of this box-machine are more fully pointed out in the following specification and claims, and illustrated in the accompanying drawings, in which- Figure 1 represents a central longitudinal section of a box-machine embodying my invention. Fig. 2 is a plan or top view thereof with part broken away. Fig. 3 is a vertical section in the plane a; 00, Figs. 2 and at. Fig. 4. is a top view of the feed-table and the sheet or strip adjusting device attached thereto. Fig. 5 is a vertical section in the plane y 3 Fig. 2. Fig. 6 is a horizontal section in the plane 2 2, Fig. 3, showing the folding-wings and their actuating mechanism. Fig. 7 is a transverse section of a cutter-roll. Fig. 8 is an elevation of the same. Figs. 9, 10, 12, and are perspective views, on a larger scale than the preceding figures, of various forms of cutters and cutter-heads. Fig. 11 is a perspective of a die for the cutters. Fig. 13 is a per spective of a creaser. Fig. 1a is a similar view of a die for such creaser. fig. 16 represents various devices for securing the cutters, creasers, and dies to the cutter-rolls. Fig. 17 is a perspective of a section of a feed ing-segment. Fig. 18 is a face viewof a blank when properly cut and creased. Fig. 19 is a plan or top view of a modification of the folding-table. Fig. 20 is a similar view of the guide-plate. Fig. 21 is a sectional view showing supplemental rolls for color-printing. Fig. 22 is a plan View of a portion of a modification of the cutter-roll. Fig. 23 is a transverse section of Fig. 22. Fig. 24 is a crosssection of a modification ofa printing or feed roll.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates a frame supporting the working parts of the machine. At .the front end of the frame is located a table, B, upon which rests the sheet or strip from which the boxes are to be manufactored.

O G are rollers which feed the sheet for ward to the cutter-rolls E E,whereit is properly cut and creased. It being essential that the sheet should be fed forward, at each revolution of the feed-rolls O O a distance equal to the length or depth of the blank to be cut, the upper feed-roll, G, is made sufficiently large in diameter to permita length of feed requisite for the largest blank; but its periphery does not come into contact with the sheet, as such feed must be varied with different boxes. For this purpose, feeding-segments D D, Figs. 1 and 3, are secured to said roll 0, each of which consists of pronged sections (1 d, Figs. 1 and 17, that are adjustable toward and from each other, so as to vary the ultimate length of the segments. This adjustment can be effected by providing the sections with the longitudinal slots (1 through which extend the fastening bolts or screws whereby the sections are secured to the roll. The lateral adjustment of the segments D D is effected by providing the roll 0 with series of tapped holes, or, preferably, such holes may be subsequently drilled and tapped as conditions may require.

The cutter-roll E is provided with cutters F and with creaser-dies G, both of which are adjustable within longitudinal grooves or ways 6, as shown in Figs. 7 and 8, or also in peripheral ways 0, intersecting the longitudinal ways 0, as in Figs. 1 and 2. Each cutter consists of a bent or angular body or head having a flange, f, which is slotted atf, either longitudinally, as in Fig. 9, or transversely, as in Fig. 10, and ablade, f", containing a sharp or pointed edge. This bladef is forced into a longitudinal recess in the body or head and is held therein by friction, such being the simplest method of securing said blade to the body or head. The cutters are secured to the roll by bolts f, of the usual construction. The cutters containing the longitudinal slots, Fig. 9, are intended to be used when the roll is provided with intersecting ways 6 and e, and those with the transverse slots, Fig. 10, when the roll has only longitudinal ways 6. The dies F for the cutters are secured in a similar manner as the cutters to the lower roll, E, and

are provided with flat or nearly flat workingfacesf Fig. 11.

The creasers G are adj ustably secured in the roll E, their bodies or heads having flanges 9, containing slots 9 Fig. 13. Said creasers have their blades 9 provided with blunt or rounded edges g, and the dies G, Fig. 14, for,

the creasers, which are secured in the upper roll, E, have concave faces or cavities 9', so that the material of the blank is pressed into said cavities and a crease is formed.

By forming simply creases or depressions in the blank the box is not materially weakened and the blank can be readily folded, and the folded parts have butlittle tendency to return to their original positions.

It will be observed that by the proper adjustment of these cutters and creasers and their dies, and by adjusting the feeding-sections on the feed-rolls O G, a blank of any desired outline or dimensions, within limits, can be cut.

The cutter and creaser blades and the dies, instead of being secured in the bodies or heads, as described,can be fitted directly into grooves in the rolls E E, Figs. 22 and 23; and in this case lifting-out recesses e are provided, into which a properly-shaped tool can be inserted and the cutter or creaser blade drawn out, as when they are to be sharpened. In this case the cutters and creasers and dies extending about the periphery of the rolls are made in sections, so that they can be fitted in the grooves. Similar lifting-out recesses 6*, Fig. 10, can be provided for the blades of the cutters and creasers, such recesses being formed in the bodies or heads, as shown. The cutter-blades for irregular forms-snch as the outlines5 6 7 of the blank, Fig. 18-can be inserted in a properlyshaped body or milled out of steel. On inspection of the drawings it will be noticed that for any particular size of box-blank the cutters and creasers fill out or extend over only a definite portion of the periphery of the roll E, and consequently during that period of time in which the roll is rotating without cutting the blank must remain stationary. This is accomplished by means ofthe segments D D on the feed-rolls which feed the sheet or strip forward only a distance equal to the length of the blank,after which the upper feedroll is out of contact with the sheet.

The feeding forward of the sheet takes place simultaneously with the cutting of the blank. The sheet, after passing under the cutter-rolls E E, is received by rolls J J* J. The upper roll consists of a paste-distributingsection,J*, Fig. 2, and a separating-roll, J, which is provided with feed-segments K K in sections, as before, which are adjusted to the length of the blank as cut. This separating-roll is somewhat larger in diameter than the feed-rolls G G; or the feeding-sections are made thicker, so that their contactsurfaces move with a greater speed than the sheet as it leaves the cutterrolls,whereby the blanks are separated,it being understood that the feed and separating rolls rotate with the same angular velocity. To prevent this action of theseparating-rolls from drawing the sheet forward and out of register, in case the blank does not separate, or separates hard, a stop mechanism is situated between the feed and cutter rolls, which holds the sheet at the time of separation. This stop mechanism consists of two feed-rolls, H H*, Figs. 1 and 2, one of which, H, is rotated by the feed-segments D D, through an intermediate roll, H, and feeds the sheet or strip in conjunction with the feedrolls. A brakeshoe, it, carried by one arm of a lover, I, is normally pressed against said roll H by a spring, 2, Fig. 1, and said brakeshoe is removed from said roll by the action of the feeding-sections D upon the second arm of the lever I. The lever I is secured to a rock-shaft, 2', having bearings in the frame, and is longitudinally adjustable thereon, so that it can be shifted as the position of the feeding-segment D D of the feed-rolls is adjusted laterally for different'sizes of boxes. The spring 6 can be moved with the lever I, its upper end being received in a cap, i, the supporting-arm of When such a stop mechanism is used, it is necessary to make the length of the feedingsegments as much shorter than the length of the blank to be cut as the peripheral distance from the point of tangency of the segments with the sheet or strip to the end of the contact-arm of the lever I. To lift the brakeshoe h from the roll H, as soon as the rolls 0 O commence to feed the sheet, the section (1 of the feeding-segment D is provided with an extension, (1*, Fig. 1, which is thinner than said segment and does not come into contact with the sheet or strip, but is thick enough-to cause the brake-shoe h to be lifted from. the roll H when it comes into contact with the lever I. This extension d* reaches from the end of section at to the end of lever I.

The paste-distributing roll J f, previously mentioned, can be laterally moved on the shaft j, Fig. 2, so as to adjust it to different widths of blanks; and it is also provided with an adjustable segment, K, constructed similar to the segment D, such segment K being adjustable to the length of surface which is to be supplied with paste. Paste is supplied to the distributing-roll J by a paste-roll, L, mounted on a shaft, 1, and laterally adj ustable thereon, so that it can be moved with the paste-dis tributing roll. This paste-roll L revolves within a paste-fountain, J. The paste-roll L may be made wide enough to extend across which is adjustably secured to the frame."

IIO

the entire width of the pastefountain, and in this case it need not be made adjustable on its shaft.

The folding-table M, Figsal, 5, and 6, consists of a thin plate of a rigid material-such as hard steelwhich is secured at its front end to supports of any descriptionsuch, for instance, as a crossbar, m, which extends be tween the standards of the frame A. Above this folding-table is rigidly suspended aplate, M, which prevents the blank from buckling while being folded. This plate 1U. can be suspended, as shown in this example, from shafts a n, that are supported in vertical posts a a, secured to the bottom of the frames. The folding-table U is equal in width to the distance between the lines 1 2 and 3 t of the blank, Fig. 18.

The folding-wings O O are mounted on arbors 00, having bearings in thepostsa a, and are 0perated to move through a semicircle by means of the bentlevers P P, which are pivoted to the shafts a a, and the free ends of which are attached to the folding-wings near their hinges. The levers are depressed by means of spring pressed rods P I, that are engaged by cams Q Q, Figs. 1, 2, and 5, secured to the shaft Z, the springs returning the levers, and consequently the wings O O, to their normal posi tions. The rods P P are supported in sleeves 0" 0, which can be set at any angle about the ends of supports 0 o", movably secured in standards 0 0.

The blank, after leaving the paste and the separating rolls, is seized between a small roll, B, Fig. 1, supported in the folding-table M, and a roll, R, which is actuated by a roll, It, on the shaft Z, and said sheet is fed over the table M and below the plate M. The roll is provided with the adjustable segments S, similar to the adjustable segments D, previously described, which segments S are so located or adjusted that while the folding-wings O O are actuated to fold the blank such blank is held stationary.

That portion of the blank which contains the outer or paste-receiving flap b, Fig. 18, is folded slightly in advance of the remaining portions of the blank, so as to insure a proper uniting of the ends. lhis is accomplished by setting the actuatingcam of the proper folding-wing slightly in the lead of the other. After the blank. is properly folded it is fed forward to the pressure or ejector rolls T T, by which the folded blank is firmly pressed together. On passing from these rolls T T the blanks are piled up or received upon a moving endless apron or belt, T, which extends around two pulleys, Z, (one of which is omitted in the drawings,) from which belt or apron the blanks are removed as desired. For different sizes of boxes the distance between the lines 1 2 and 3 4, Fig. 18, will vary, and consequently the folding-table ill and plate M must be replaced by one of a proper size and the posts a a moved correspondingly. To facilitate this changing in the position of the posts a 01, their bases can be guided in ways or grooves n a in the base of the machine, Figs. 1, 2, and 6. The position of the rods 1 P, in connection with the actuating-levers P P, can be changed by shifting the supports 0 0", if necessary; but for smaller changes an adjustment of the obliquity of the rods 1? P will suffice. The rolls It R are made in sections, so that they can be varied in length, the end sections, 1' r and 1" 0", having hubs,th rough each ofwhich extends a belt or screw that impinges on the shaft. If desired, however, the roll It may consist only' of two end sections, n a, which can be moved laterally.

Instead of making the folding-table M and plate M, respectively, of one piece, they may consist of end strips, 0 0', Figs. 19 and 20,which are joined by means of toggle-levers 88, so that the same can be made narrower or wider. In this case the roll R, Figs. 1 and 20, of the folding-table is made in sections-that is, a number ofsleeves mounted on a common shaftand the support or cross-bar m is provided with slots 5', through which the fitstening-bolts extend. In order that the sheets or strips can be moved to the feed-rolls O C, so as to bring their forward ends directly to a line drawn between the rolleenters, which insures accurate feeding in register to the cutter-rolls, I provide the following strip or sheet adjusting device, Figs. 3 and at. On one side of the table 13 (preferably the right-hand) is secured, in standards, a rod, U, upon which is supported a feed-board or supplementary table, U, which is movable in the direction of its length and capable of turning about said rod as an axis. The feed-board or supplementary table U is constructed with two plane faces, a a, which can be brought alternately in ahorizontal plane above the table B. In suitable ways on each side of said table U are fitted index hands or pointers a, which can be moved in said ways and secured at any desired point by means of tl'iumb-serews. An adjustable stop, a, on the rod U, serves to limit the forward motion of the table. In the use of this device the stop a and the pointers a are so adj ustcd that if some convenient mark on the sheet or stripsuch as a printed line-is brought inline with the pointer the forward end of the sheet will be brought between the feed-rolls O 0, when said table, together with the sheet, is moved until the motion of the table is arrested by the stop 16.

Suppose the face a of the feed-board U is above the table 13. The sheet to be fed is placed upon the table I), with one edge resting upon the feed-board U, such edge being retained upon the same by the operator, the proper position of the sheet having been previously determined and the stop a properly set. As the sheet at present under the feedrolls nears its end, the feed-board U, together with the sheet held thereon, is moved forward on the rod U, and the end of said sheet or strip is brought in the proper position between the rolls 0 G, and is grasped by the same as the feeding-segments D D rotate.

After the sheet or strip is grasped by the feed-rolls C O the feed-board U is turned one hundred and eighty degrees, in this example about the rod U, in the direction of arrows, Fig. 3, whereby the sheet or strip is deposited upon the table B, and the face u of the feedboard is ready for the next sheet after such feed-board has been drawn toward the operator. By this means a sheet or strip is always ready to be accurately fed when the end of the sheet or strip previously deposited upon the table has been reached.

Then it is desired to print the blank, the type is set up on the feed-cylinder G, and ink is supplied to the same from ink-fount V, Figs. 1 and 2, by a set of receiving, transmitting, and distributing rolls, 1), as usual. To adapt the machine for color-printing, Fig. 21, supplemental printing-rolls-sueh as G" G -are arranged ahead of the feed-rolls D D, and such rolls 0 O are provided with feeding-sections D D. The necessary ink is supplied to the rolls from ink-founts V by rolls 1). Such supplemental printing-rolls being constructed and set in a similar manner to the feedrolls, the register of the sheet or strip is not disturbed.

To emboss the blank at the same time that it is cut, I make use of embossing punches and dies 20 to, Fig. 1, which are provided with slotted flanges similar to the cutters and dies F F, in the same manner as the latter. The feed or printing roll 0, as shown in;. Fig. 24., is provided with grooves or ways 0, in which are secured adjustable clamping-dogs C, such dogs consisting of a slotted plate having an inclined clamping-edge. A bolt or bolts, 0*, extend through the slots in the dogs, and their heads are within the rooves, whereby said dogs can be secured in any position on the roll. The type-plate C is provided with bevel-edges which are engaged by the dogs. By this means the cylinder is adapted for any size (within limits) of type'plate, and said type plate can be secured in any position.
