PAPER-BOX-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 429,236, dated June 3, 1890.

Application filed July '7, 1888. Serial No. 279,266. (No model.)

T0 at whom it may concern:

Be it known that I, GEORGE M. GRIswoLD, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvement-s in Paper-Box-Making Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in machines for making paper boxes, but more particularly that class of boxes used for the packing of cigarettes, candies, and similar goods, and which primarily consist of an outer case or covering and a drawer, in which the goods are contained and which is designed to slide into the case.

The machine herein described shapes and completes the drawer.

The objects of my invention are, first, the formation of the blanks-two at each operationfrom a continuous strip of paper fed from a reel or roll to the several combinations of mechanical elements which are to operate thereon in its passage through the machine; second, to properly apply to the paper the glue by which the blanks are finally retained in their finished shape; third, to print upon each blank as it is fed any matter-such, for instance, as the manufacturers name and address or the quantity or quality of the goods the box is designed to contain; fourth, to automatically crease and fold the cut, glued, and printed blank into the shape in which it is finally to be retained by the glue, and, fifth, to so nest and pack the completed boxes as they come from the machine that the glue which has been applied to them may have ample opportunity to set hard and firm, and the tendency of the folded box, owing to the elasticity of the papers, to return toward its flat position or out of its folded shape in any wa r be thereby obviated.

This nesting or packing of the completed boxes, as and for the purpose above set forth, is most particularly the object of my present invention, and I do not wish to be confined to the precise details of construction and combin ation of mechanical deviceswhich I employ in this machine for the accomplishment of that result, since many changes of the mechanical structure may be made without departing from the spirit and aim of my invention, which contemplates the nesting of each completed box within the one which has next preceded it, so that each shall be firmly held as against change from its completed form.

WVith these ends in view my invention consists in the structure and organization of. mechanical elements, which I will hereinafter fully set forth, and then recite in the claims.

I11 order that such as are skilled in the art to which my invention appertains may fully understand my improved machine, I will describe the same in detail, I reference being had to the accompanying drawings, which form a part of this specification, and in which Figure 1 is a side elevation of my machine; Fig. 2, a similar view from the other side; Fig. 3, a central vertical longitudinal section; Fig. 4:, a plan view; Fig. 5, a detail plan View of the cutting-block and the folding-plate and folding-die; Fig. 6, a bottom plan of the cutter-head and cutters and the folding-plungers. The head, Fig. 6, interacts from above downward upon the plate shown at Fig. 5, as will hereinafter appear. Fig. 7 is a bottom plan of the machine, the printing mechanism being removed; Fig. 8, adetail of the printing mechanism, partly in section; Fig. 9, a detail section through the forward end of the folding plate, plunger, and folding-dies, and showing the carriage upon which the nested boxes are supported and carried downward as they come from the machine; Fig. 10, a plan view of a blank-cut to proper form and ready to be folded; Fig. 11, a perspective of a number of the completed boxes nested and in the position in which they lie upon the carriage; Fig. 12, a partially folded box; Fig. 1 3, a detail vertical section through the folding-plunger, the sliding carriage, and the ways for the latter, a number of boxes being shown upon said carriage in the position in which they are deposited by the plungers.

Similar reference numbers and letters denote the same parts in all the figures of the drawings.

1 is the frame of the machine, and upon an extension 2 from the end of the said frame is mounted a reel 3, upon which the roll of blank paper is held, and from which it is drawn between guides 4: and over a roller 5, which is journaled and free to revolve upon a shaft whose bearings are in the frame. From this the strip lettered x passes upward to the printing mechanism and thence to the devices, whereby the glue is applied, which mechanisms are operated as follows, reference being particularly had to Figs. 2, 5, and 8.

G is the transversely-extended pulley-shaft which receives motion through the bandwheel 7 through a suitable clutch 8, and 9 is a pinion on the pulley-shaft which meshes with and drives a geared wheel 10, fast upon the main shaft 11. The motion of the main shaft is in the direction indicated by the ar row upon the gear 10 in Fig. 1.

At the end of the main shaft, away from the gear 10, is secured a crank 12, which, through a pitman 13, actuates a bell-crank lever 11-. This bell-crank is pivoted upon a short shaft 15, journaled in the side of the frame.

16 is a pawl, which is pivotally secured to that arm of the bell-crank operated by the pitman.

17 is a gear secured upon the shaft 15, and 18 is a ratchet-wheel secured against the side of the gear last referred to. The to-and-fro movement which the bell crank derives through the pitman from the main shaft causes the pawl to intermittently rotate the ratchet by engagement with the teeth thereof. As heretofore stated, the gear and ratchet wheels are secured together, so that the latter partakes of the same degree of rotation as the former. The ninting-roller 21 is driven by the gear 17 through a smaller gear 19 upon the same shaft 20 as said printing-roller. Upon the peripheryof the said printing-roller are arranged in any ordinary manner suitable types for effecting the printing operation. Said types print against the surface of a platen-roll 21, over which the paper passes.

22 is an ink-fount suit-ably secured upon the end of the bed. lVithin the fount is journaled a roll 23, which acts as a distributer for the fount, and receives a slight intermittent rotary movement from a small ratchetaud-pawl mechanism which 1 have thought it unnecessary to specially describe, butv is shown at 24, Fig. 2.

The ink is taken from the distributer by a small roller 25, journalcd in a movable frame 26 at the under side of the bed of the machine, and by means of a spring 27 said roll is normally held in contact with an intermediate roller 28, which latter rotates against a roller 29. The inking mechanism just described is driven by a small belt 30, which is shown as passing over shaft (3, but which may equally as well be connected to any eonst-antly-rotating shaft in the machine. The roller 29 takes ink from the roller 28 and supplies it to the type-bearin g roller. While the roller 25 is in contact; with roller 29, which contact is effected by the action of the spring 27 on the frame, it revolves with it by friction and im parts ink thereto. At each turn of the machine, however, said roller 25 and its frame are carried along longitudinal of the bed against the action of the spring and into contact with the distributing-roll in the fount. This is effected by means of a toothed wheel 31, secured upon and carried by the shaft 15, and which by engagement with. a tooth or pawl on the frame carries the latter along beneath the bed until the roller engages with the distributor in the foun t and receives therefrom a portion of ink. \Vhen the wheel by continued rotation passes out of engagement with the pawl, the frame and roll are re turned to their normal position by the spring :27 and the ink derived from the fount transmitted to the intermediate roller, as heretofore described.

The intermediate roller 28 has its bearings beneath the bed of the machine, and for the purpose of more effectual distribution it is given a slight traversing movement from a pivoted bent lever 10, which-is actuated by a cam t1, secured to and carried by the toothed wheel 10.

33 is the gluc-fount,to which heat is supplied by suitable steam-connections 34:. A shaft 35 is journaledacross the top of the glue-fount, and upon said shaft are secured printingarms 35, which take up glue as they revolve through the fount and apply it from their faces to the paper strip as the latter is drawn over them. Said arms are so placed on the shaft and the shaft so driven that the glue is printed upon the strip atthe proper places relative to the cutting and folding operations to which it is subsequently subjected. The shaft derives an intermittent rotation from the bellcrank lever 14; through the pitman 30' by means of a rachet-wheel 37 and a pawl 38. The ratchet-wheel is fast on the shaft and the pawl pivoted upon a crank 39, whose end is attached pivotally to the extremity of the pitman, and which is also loosely journaled upon the shaft 35. From the glue-printing devices the strip passes outward and around a tension-roller 42, j on rnalcd upon a standard or support 4.3 at somelittle distance from the machine. The object in carrying the strip outward and around this roller is to give the freshly-applied glue an opportunity to set somewhat before the paper is operated upon by the cutting and folding devices. After returning from the roller to the machine the strip is introduced upon the fiat top of the bed and passes between guides 4 1 to the slitting and feeding rollers 45, which divide the paper longitudinally into two strips of equal width, and also by their grasp upon said paper feed it along intermittently as is required.

The slitting operation is necessary, since in the machine shown and described herein the operating mechanism is in duplicate and simultaneously produces boxes at each operation. The slitting and feeding rolls just 1c about the center of the upper roll.

ferred to are journaled one above the other, the under roll with its periphery just flush with the surface of the bed- The lower roll is driven from the gear 17 through the gear 46, which by engagement with a duplicate thereof imparts synchronous movement to the upper roll.

47 is the slitting-knife, which is secured It runs against a shoulder upon the lower roll and thereby severs the paper by a shear cut. \Vhen the paper has been slitted, the rolls feed the two strips forward beneath the cutvupon the bed as the dies ascend.

ting-dies, which descend and blank out the paper into the shape shown at Fig. 10, those portions which constitute the scrap or waste, and are driven downward and permitted to escape through openings in the cutting-block, which appear at Fig. 5 and are numbered 49.

The die, simultaneously with the blanking operation, creases the blank in the proper places for the folding up thereof into completed form, as shown by dotted lines at Fig. 1.0. Flat springs 50, secured to the face of the dies, serve to hold the cut blanks down The blanking operation forms the blank complete, except that it does not sever it from the strip at the line a, Fig. 10. Said blank is left thus connected, so that it may be fed forward with the strip by the push of the feeding-rolls into position for the final operation of folding. The final severing is effected simultaneously with the bending up of the sides and ends of the blank by the plungers.

The downward-cutting movement of the dies 48, whereby the blank is cut as aforesaid, is effected through a lever 51, which is hung longitudinally beneath the bed, and is operated in proper time by its engagement through a stud with a profile cam 52 on the main shaft, a cross-head 53, and links 54, which connect the ends of the cross-head with the cutter-head 55, on which the dies are mounted. The said cutter-head slides upon ways formed on the upward extension 56 on the frame. When the blanking-dies have been raised out of engagement with the cutter-block, the shaped blank is fed along to a position over the folding-dies 57. (Shown at Fig. 5.)

It is here proper to state that the folding of the blank shown at Fig. 10 into the shape shown at Fig. 12 is accomplished by first trimming the ears A upward at right angles to the face of the blank and then bending the side flaps B, of which the cars A form a part, upward at right angles to the blank. This last operation leaves the ears A projecting inward across the face of the blank and edgewise toward it. The creased end apron C is then folded upward and its end flap, to which the glue has heretofore been applied, as described, doubled over upon itself and upon the ears A, whereby the boxis retained in the position shown at Fig. 12. The upward turning of the ears A is effected by means of folding-feet 58, which are formed upon the die-block and move with said block.

As will be understood, the operation of the feet upon the blank is always one step behind that of the cutting-diethat is to say, their operation upon the cut blank is simultaneous with the cutting out of the next succeeding blank from the strip. These foldingfeet bend up the cars A against the edges of blocks 59, below the plane of which the faces of the feet pass in their descent.

Having performed the operation of folding the ears upward the feet ascend with the cutter-head, and the plungers 60, whose shape is shown in the plan View, Fig. 6, descend upon the blanks and drive the latter down into the folding-dies shown at Fig. 5. This operation turns up the edges B and the end flap 0, and causes the ears A to assume the edgewise position toward and across the face of the blank shown at Fig. 12. A small straightedged cutter 80, secured at the rear of each plunger on the cutter-head, severs the blank finally from the strip previous to the downward action of the plungers.

In Figs. 5 and 9 are shown springs 87, se cured at the sides of the die-openings. The function of these springs is to elevate the strips of paper between and at the sides of the blanks, so that said strips may not be carried downward by the plungers.

The'plungers are mounted upon extremities of rods 62,supported in guideways in the upward extension of the frame. The properly-timed vertical reciprocation. of these rods is obtained from a profile-cam 63 on the main shaft through a lever 64, operated by said cam through a stud or roll connection, an upwardly-extended connecting-rod 65, a rockarm 66, to which said rod is attached, a journaled rock-shaft 67, upon which the arm 66 is mounted, and an arm 68, which is connected to a cross-head 69, secured to the plungerrods.

After the blank has been driven down into the folding-die, there remains only to fold the glue-coated apron C over upon itself and upon the inwardly-turned.ears, so that the glue, by adhesion to the parts just specified, may hold the box in shape. This folding operation is effected by means of a pair of folders 79one for each boxwhich are operated from beneath the bed. These folders are shown, at Fig. 9, and their move- ITO ment and method of operation are as follows: They have a quadruple movementfirst, upward to a plane higher than the edge B of glue. As the side flaps ll are connected by the ears to the end of the box (see Fig. 12) they are thereby held in their bent position at right angles to the bottom of the box. It will be perceived that the front ends of the plungers are cut away as to their central portions, so as to leave only the narrow projections 85. (See Fig. 6.) The folders work between these projections, while the plungers still hold the boxes firmly in the dies. The upward movement of these folders is derived from a cam on the main shaft through a lever 70, which is operated by said cam like the levers heretofore referred to, and whose end projects under and is adapted to raise the standard 7 1, on which the folders are mounted. The lower end of this standard has a sliding connection with two pins 72, mounted upon a rock-shaft 73, and this shaft receives from a lever 74, operated by a cam 74: on the main shaft, the movement which it imparts in the form of forward and back motion to the folders. Thus the combined action of the two cam-actuated levers just described imparts to the said folders the compound movement whereby the final holding is effected in the box. The varying positions of the folders is shown in dotted lines at the detail, Fig. 9. When the box has been thus folded in the die, its bottom rests upon a small carriage 75, which is adapted to slide upon an inclined way 7 (3, and is normally held against the bottom of the lowermost box by the pull of a counter-weight 7 7. The box first made, as will be readily understood, rests directly upon this carriage. The second is thrust into the first, the third into the second, &e., and as the boxes are thus piled one within another (see Fig. 11) the carriage is forced downward along its way against the pull of the countenweight and forming a support for the stack or nest of boxes. The boxes are prevented from rising oil the carriage by a shield 78, which projects downward parallel to the ways upon which the carriage runs. \Vhen the carriage has been pushed to the end of its track by the boxes, those at the bottom maybe removed, and the carriage will be drawn upward against the now shortened pile of boxes, so as to support them. I find, however, that it is unnecessary in practice to remove the boxes, since they will, after the carriage and way are filled, rise over the end of the carriage and fall by gravity into a basket orother receptacle prepared for them. By this means the freshlyglued boxes are tightly held in the pile for a period of time sufficient to allow the glue to set firm and hard enough to obviate any danger of the box ungluing or becoming misshapen by the elasticity of the paper.

In theoperation ofthe machine it is to be understood that the intermittent movements by which the printinga'oller, the gluing mechanism, and the feeding and slitting rolls are actuated are all. so timed as to admit of the pro1i)erly-timed action of the blanking and the folding mechanism. The feeding and slitting rolls, operated as hcreinbefore described through the bell-crank lever 14 and the parts 15, 16, 17, and 18, draw forward the paper strip, and during this forward feeding the printing and the application of the glue are effected. Meanwhile the blanking and folding mechanisms are at rest. \Vhen the feeding ceases, the cutter-head descends and blanks the strip, and simultaneously the foldingfeet bend up the ears on the blank cut out by the previous operation of the dies. Then as the cutter-head ascends the plungcrs descend and force the blank just operated on by the folding-feetinto the die, where, before the plungers recede, the folders complete the box. Then the feeding recommences and the blank paper for the next box is brought under the die and the cut blank fed forward for the folding devices.
