MACHINE FOR MAKING PAPER BOXES.

SPECIFICATION forming part of Letters Patent No. 594,049, dated November 23, 1897. Application filed February 2, 1897. Serial No. 621,664. (No model.)

To aZZ whom it may concern:

Be it knownthat ANDREW J. XVHITE, deceased, and we, J osnPHCRAMER and HENRY P. GAINEs, citizens of the United States, residing at Cincinnati, in the county of Hamilton and State of Oh i0, have invented certain new and useful Improvements in Machines for Making Paper Boxes, of which the following is a full, clear, and exact description, reference being had. to the accompanying drawings, forming part of this specification.

Our invention relates to machines for making paper boxes or cartons from a continuous roll of material; and the object of our said invention is to produce a machine which is simple and durable in construction, entirely automatic in its operation, adjustable to make different sizes of boxes, and having a large capacity for Work and it consists, mainly, in certain combinations of mechanism adapted to act successively upon a paper or pasteboard strip and produce therefrom complete and perfect boxes or cartons.

It consists, further, in certain details of construction and various combinations and arrangements of part s, all as will be hereinafter set forth, and specifically pointed out in the claims.

The same letters of reference are used to indicate identical parts in all the figures.

Referring to Figs. 1, 2, 3, 4, 5, and 6 of the drawings, A represents the frame of the machine, which is an elongated table of any suitable materiaL-the precise-construction of which is immaterial and may be modified or altered according to the judgment of the designer.

In the front end of the frame. is suitably mounted a reel, around which is wound acontinuous strip of strawboard or other paper B. This reel is supported in bearings in the frame and is removable in order to permit of the substitution of another when the roll of paper is exhausted. The strip B is carried from the reel over a guide a, which is adj ustably and transversely mounted on the frame, and thence between a pair of transversefeedrolls b b, suitably mounted in hearings on the frame. After leaving the feed-rolls b I) it passes between a pair of scoring-rolls O C, which are provided with a series of transverse scoring-knives, adjustably mounted on the said rolls, the purpose of which is to make cross-scores on the strip 13, indicating and creasing the lines of the portions which are to be folded up to form the ends of the boxes. The construction of these scoring rolls is shown in detail in Figs. 15 and 16, and may be described as follows: The two rolls 0 O, suitably mounted in bearings provided therefor, supported on the frame of the machine, and the upper one of which is vertically adjustable to and from the lower one by setscrews, as seen in Fig. 5, are provided with collars c at their ends, adjustably secured on the said rolls by means of set-screws. The transverse knife 0 of each pair is rigidly secured to the collars c at each end and is free from the shafts or rolls 0 C, while the knife C of each pair is rigidly secured to the rolls 0 O and free from the collars c. It will thus be seen that the distance between the scoring-knives c 6 can be readily adjusted by loosening the set-screws of the collar 0 and moving the same around, so as to bring the knife 0 either closer to or farther away from knife 0 to decrease or increase the distance between the cross-scores. The scoringknives c are provided on one end with slots 0 in which are adj ustably bolted, by screw 0", short knives o slightly projecting beyond the edges of the knives c? to completely sever the narrow strip 0, Fig. 17, at the edge of the blank to prevent double lapping of the paper at the lid portions of the box. The driving mechanism for these scoring-rolls, together with the various other rolls, will be hereinafter described. After passing between the transverse scoring-rolls C C the strip B is guided between a pair of slitting-rolls D D, (shown more clearly in Fig. 9,) and which are adapted to 'cut the longitudinal slits 0 between the creases c on the said strip 13. (Shown in Fig. 17.) The'construction and operation of these slittingrolls may be described as follows, (see Figs. 9 and 10:) The lower roll D is suitably mounted in bearings provided on the main frame and has a series of disks cl, four in number, mounted thereon equidistantly apart and capable of adjustment by means of set-screws. The upper rollD is arranged directly above the rolls D and is mounted in sliding bearingseandhas mounted thereon a series of disks (Z, corresponding in number to those 011 lower roll, and provided with knife-flanges (Z all equidistantly apart and capable of adjustment laterally by means of set-screws. The disks d are di rectly above the disks (1, so that when they descend the knife-flanges shear against the edges of the lower disks d to cut the slits in the paper. Directly above the rolls D D is mounted a shaft E, provided with suitable bearings and to each end of which is eccentrically pivoted a pitman e. The lower ends of the pitman e are in turn loosely pivoted to the sliding bearings e, which support the roll D. The shaft E, which carries the shaft D, has its bearing-boxes vertically adjustable by the set-screws shown in Figs. 5 and 14, so as to adjust the shaft D to and from the shaft D. Suitable driving mechanism for these two shafts is provided and will be hereinafter more fully described. It will be seen from the foregoing that the revolution of shaft E imparts a Vertically-reciprocatin g movement to roll D, while the driven gear (1 imparts a revolving motion to the same, which movements, when properly timed and adjusted, cause the slitting-knives to operate intermittently on the strip B and cut the slits c in their proper places. After leaving the slitting-rolls the strip B passes between a pair of scoring-rolls FF, Fig. 5, suitably mounted in the bearings provided therefor. The upper roll F is provided with a series of scoring-disks f, four in number, equidistant apart and adjustable laterally by means of set-' screws and the shaft of which is adjustable vertically by means of set-screws, as seen in Fig. 5, to regulate the depth of the creases. The lower roller F is provided with a similar number of scoring-disks f, located so that they come in contact with the upper surface disks at about their middle, and which disks are also adjustable laterally by means of setscrews, so that the width between the creases can be changed when it is desired to change the size of boxes. These scoring-disks f act on the under side of the strip B and make four continuous longitudinal creases,thus virtually dividing the strip into five longitudinal divisions, substantially as shown in Fig. 17 of the drawings. The strip B now passes under a spring-pressed roll g, Fig. 5, mounted in suitable bearings provided on the frame of the machine. Directly under this roll g is a shaft carrying a narrow paste-wheel g, suitably j ournaled in bearings provided therefor. The paste-wheel g is provided with a pastereceptacle 9 mounted on the bed-plate of the machine, and is adjustable 011 its shaft. An adjustable scraper g is provided, as shown in Fig. 5 of the drawings. The paste is applied continuously at the under edge of the strip B by means of the wheel g. The strip B is now carried to the folding mechanism, which we do not claim as novel and describe but briefly. A pair of folding-guides h, Figs. 6 and 8, serve to turn up the sides of the strip, while the guide-wheels H bear on the center, and the strip passes in succession to a series of folding-guides, as h 71,2 h 3y the time it reaches guide 77. it has been turned over completely and passes under a guide-roll 71. and thence to a pair of pressing-rollers I, which serve to press it out fiat and also to cause the pasted edge to closely adhere to the other edge of the strip 13. The strip B is next passed between a pair of feed-rollers K, which are of the same diameter as the feed-rolls b in the front of the machine and which serve to pull the paper through the machine at the proper rate of speed.

The cutting-off mechanism is shown in detail in Figs. 11 and 12 and may be described as follows: After the strip B, which has now been scored, slitted, pasted, and folded to form a flattened tube, as heretofore described, passes from the feed-rolls K it is guided between the cutting-knives Z m, which revolve in opposite directions at a rate of speed'so timed as to cut off the folded strip in proper lengths, which is in the transverse center of the slitted portion 0 and indicated by a dotted line Z in Fig. 17.

The construction of the cutting mechanism is as follows, referring to Figs. 11, 12, and 18: The lower knife Z is rigidly mounted on a shaft Z journaled in bearings mounted on the frame A, and revolves by means of suitable gearing in the direction of the arrow 00. The upper knife m'i's loosely mounted on its shaft m, journaled in suitable bearings, and revolves in the direction of the arrow as. A stop-plate 'm is rigidly secured to the shaft in, against'which the knife bears when it is in its normal position. A coiled spring a is provided, one end of which is secured to the shaft and the other end of which bears against the under side of the knifem. The object of this is to allow the knife on to yield when it comes in contact with the lower knife Z, the spring n serving to throw it back into its normal position against the stop-plate m in time for its next operation. These two knives l m are so set on their respective shafts as to just overlap each other when they come together' to form a perfect cutting edge. The revolution of these knives must be so timed as to make a cutdirectlyin the transverse center of the slitted portions of the strip, and from the above-described construction a'cleanand positive cut is insured.

The driving mechanism of the machine of the first nineteen figures may be described as follows: The power is transmitted from the d riving-belt to the pulley M, which is mounted on shaft N, which carries the lower feed-roll K. On this same shaft is a small gear 2', which meshes with a gear 11 on the upper feed-roll shaft K. On the opposite end of the shaft N is a sprocket-wheel 0, which is connected by a chain to a sprocket-wheel 0', mounted on the shaft P of the lower front feed-roll b. On the same shaft is a gear 0 which meshes with a gear 0 on the shaft of the upper feed-roll b. The speed of these two sets of feeding-rolls is the same and regulates the speed at which the strip B must travel. On theshaft p is a sprocket-wheel 19, connected by a sprocket-chain with a sprocket p on the lower shaft of scoring-roll F. On the same shaft is a gear 7", which meshes with a gear r on the upper scoringroll shaft F, which imparts the proper rotary motion to these shafts. On the shaft D is a gear r which is connected to gear r by an intermediate gear r On the opposite end of the upper scoring-roll shaft F is a gear 8, which meshes with an intermediate gear 3, which in turn meshes with a gear 01 on slitting-roll shaft D, thus imparting the proper rotary movements to the slitting-roll shafts. On the paste-wheel shaft is a sprocket-Wheel 8 connected by chain with a sprocket s on the shaft F.

011 the shaft N is a gear 15, which meshes with an intermediate gear t, which in turn meshes with a gear 25 on the lower knife-shaft P. On the opposite end of the shaft Z is a gear i meshing with a gear t on end of upper knife-shaft m for imparting the proper revolving motion to the cutting-off knives. The gear t is mounted in a slotted arm a, which arm is pivoted to the frame by a bolt it, which passes through said slot. By'means of this slot the ar'm u and gear t can be adjusted so as to allow the said gear 25 to mesh with different-sized gears when it is desired to change the speed of the cutting-off knives.

On the end of the shaft 1 is a sprocketwheel 11, which is connected by a chain to a sprocket-wheel v on the lower transverse scoring-roll shaft O, which chain also connects with a sprocket-wheel w on the eccentric shaft E for imparting the proper motion to said shaft E, which operates the slitting-knives. A small gear 11 is also mounted on the shaft 0, which meshes with a gear 0 on the upper shaft'O, thus imparting the proper rotary movement to the transverse scoring-rolls. It will be readily understood that when it is desired to change the length of the boX it is only necessary to change the gears 15 and t and substitute therefor either larger or smaller gears to decrease or increase the number of revolutions of cutting-off knives. The, changing of speed of the cutting-off knives also changes the speed of the cross-scoring rolls O O and the eccentric shaft E correspondingly as they are driven directly from the cutting-off shafts. This operation would either increase or decrease the length of the boxes and the distance between the crossscores and the length of the slits, as may be desired. I

By adjusting the distance between the scoring and slitting knives on their respective shafts we can get the proper Widths for the different-sized boxes heretofore described.

The system of gearing is what we are at present using with good results, but it is somewhat complicated and could be simplified, and it would not be departing from our invention to change this mechanism, and in Figs. 20 to 23, inclusive, we have shown the machine arranged to be driven by shafts and gearing, of which A is the main power-driven shaft meshing by beveled gears with the transverse shafts of the machine. In these last-named figures there is the further modification in that a tension device for the paper is applied to it before it reaches the scoring or slitting mechanisms. This is clearly illustrated in Figs. 20, 20, and 23, Where the paper is made to pass under a rod a, hung in a vibrating frame suitably mounted on the table, and thence up over a fixed rod 19 and then onto the scoring and other mechanisms, as seen particularly in Fig. 20*. The frame of'the rod a is provided with a segment-rack c pivoted, as zit-d on the side of the table. This rack is engaged by a Worm e on a shaft f extending to the rear end of the machine and provided with a beveled gear g meshing with a corresponding gear h on a hand-Wheel shaft 2 provided with a hand-wheel 3' in such manner that the attendant at the end of the machine Where the finished and cut-off boxes are delivered may instantly rotate the shaft f to vibrate the rack 0 and, thereby shift the position of the rod a and regulate the tension of the paper being drawn through the machine. By this means great accuracy in the scoring, slitting, and cutting off of the paper is secure to obtain boxes of uniform dimensions.

Having thus fully described our invention We claim- 1.
