PAPER-BOX STACKER AND DRIER.

SPEGIFICATIQN forming part of Letters Patent N 0. 694,634, dated March 4, 1902.

Application filed May 11, 1901.

To all whom it may concern:

Be it known that I, GEORGE M. GRISVVOLD, a citizen of the United States,'anda resident of New Haven, in the county of New Haven and State of Connecticut, have invented certain new and usefulImprovements in Paper- Box Stackers and Driers, of which the following is a specification.

My invention relates to new and useful improvements in paper-box machinery, and especially to that classknown as stackers or driers, the same being designed to receive various styles of square and rectangular boxes or tubes of boxes as they are delivered from their respective styles of box-- forming machines and to successively close and stack them one against the other in'a uniform line and in a manner to retain the folded and glued edges together to insure their drying.

Heretofore the more complete types of square-paper-box machinery have been provided with belt conveyers or other complicated and bulky drying mechanism which retains the glued edges of the boxes in their a folded position while drying, so as to prevent them from opening when finally discharged from the machine? /The drying apparatuses, and particularly those employing conveyers, have been of an objectionably large construction, consuming zit great amount of floor-space in the shops where they are employed, and, furthermore, do not perform the work for which they are intended as perfectly as de sired. t

It is therefore the object of my invention to provide a ma ine, which shall be of a com pact, simple and durable construction adapted to be set up adjacent to various styles of box-forming machinery, in a manner to receive the successive boxes as they are delivered from such machinery in a folded and glued state; to retain the glued edges of the said boxes in their relative position; to produce a machine which does not have to be operatively connected or timed with the boxmachine with which it is to operate; and

. further to provide a device for stacking the boxes one against the other in a compressed form so as to prevent any opening of the seams and to insure the proper drying of said seams. Finally, to do this sufficiently rapid Serial No. 59,823. (No model.)

to receive the entire product of any of the modern types of machines, including those known as the double 7 tube machines em ployed in the production of cigarette-boxes. My invention is equally well adapted to compress and stack tubes as they are received from any of the practical styles of refoldersthat is, machines which refold tubes to insure the easy access thereto of the drawer or I inner member.

.an end view as seen fromthe bottom of Sheet 1,

the legs being broken away. Fig. 3 is a transverse cross-section taken on line 3 3 of Fig. 1,

illustrating the feed-rolls, belts, and trough operating in conjunction therewith. Fig. 4 is a detail horizontal sectional plan View through the two sets of feed-rolls, as will be later more fully described. Fig. 5 shows a perspective View of an end of a tubular member of a box such as is refolded by the re folding-machines referred to and such as my machine is designed to stack. Figs. 6 and 7 show a plan View and transverse cross-section of a modified form of my invention, the same being a double stacker adapted for use in connection with a double-tube machine and is designed to stack practically double "the'number of boxes as the previously-described construction.

Fig. 8 is a transverse cross-section of' another form of my invention, the same being adapted for use instacking larger boxes, such as one-pound starchboxes, and in which the employment of belts is dispensed with.

Referring in detail to the characters of reference marked upon the drawings, 1 indicates a suitable frame upon which the main bed 2 of my machine is mounted; 3, the table upon which the boxes are successively stacked one against the other and retained until dried. The outer edge of this table may be pivoted, as at 4,'and the inner portion supported on ICO - appears in Figs. 1 and 2.

adjustable screws 5, located adjacent to either side of the base-plate 2, before mentioned. The purpose of this adjustable construction is to permit the table to be raised and lowered to or from the top roll in a manner to accommodate different widths of boxes, as will be apparent.

Upon either end of the base-plate 2 are mounted vertically-disposed plates 6 6, which are substantially alike in construction and upon which all of the operative parts of my mechanism are mounted. These plates may be located at any desired distance apart and the intervening train of mechanism lengthened or shortened to better accommodate different lengths of boxes, as will later be more apparent.

Power is applied to the machine through the medium of the belt-wheel 7, mounted upon the short shaft 8, journaled on the hearing 9, secured to the plate 6, and having a beveled pinion 1O uponits opposite end, as clearly This beveled pinion meshes with the bevel-gear 11, mounted upon a shaft 12, extending longitudinally of the machine and journaled in the two end plates 6, before mentioned. The bevel-gear 11 has secured thereto a plain gear 13, which meshes with a smaller gear 14, mounted upon the reduced end of the roll 15, arranged parallel with the shaft .12, before mentioned, and likewise journaled in the end plates 6. These rolls are provided with a series of grooves 16 at equal distances apart, the purpose of which will be later described.

Referring to Figs.'3 and 4, it will be seen that upon the shaft 12 is mounted a series of pulleys and disks 17 and 18, respectively, which comprise the main features of my feeding device. These pulleys are substantially alike in construction and are provided with a set-screw 19, by means of which they are secured to the shaft 12, and are further provided with a suitable annular recess 20 to accommodate one of the series of feeding-belts,which will again be referred to. The opposite ends of said pulley are further recessed, as at 22, to accommodate the hubs on the disks 18, before mentioned. These pulleys are, as before mentioned, firmly secured to the shaft 12 and are spaced at an equal distance apart to permit the free rotary movement of the disks 19 therebetween, which latter in practice are preferably formed of aluminium and as light as possible to insure their free movement. .This series of pulleys when assembled as shown form the main feeding-roll, the length of which is determined only by the size of machine desired. Said disks 18 are provided with a series of cams 23, having notches 23 on one side There may be any desired number of these cams, six being shown in the main figure, while but four are shown in Fig. 8. Said cams project out slightly beyond the main body of the roll and in practice freely pass through the grooves 16 in the coacting roll 15. The notches of said cams serve to form a pocket, into which the lower edge of the box rests to insure the proper alinement thereof and to retain and guide it against the stack. As the boxes are moved down the disks are automatically turned thereby, and their projecting cam-surface serves to shove said stack outward, making room for the successive boxes as they are delivered, and the notches 23 simultaneously guide the lower edge of the box on between the stack and roll or vertically-disposed stripper 24. (See Fig. 8.)

Upon the end plates 6 6 is secured a casting 24, having a longitudinal inclined surface 25 and a vertically-disposed post 26 at either end, in which a rod 27 is mounted. Adjacent to the bearings of this rod is pivoted an arm 28, the forward end of which has journaled therein a roller 29, serving as an idler,, over which a series of belts 30 travel. These belts also connect with and are driven by the roll 15, before mentioned, adjacent to the inner operative faces of this series of belts. A guideplate 31 is provided and forms one side of the receiving-trough. Said trough serves to deflect the boxes as they are received down between the belts and rolls. This guide-plate extends through the length of the machine, its opposite ends being secured to arms 32, attached to a rod 33, the latter being mounted in post 34 at each end of said rod and secured to end plates 6. Upon this rod 33 I also mount a series of arms 35, having suitably-divided free ends to straddle the belt 30, before mentioned, and serve as a guide for the same to retain them in their proper relative positions. The tension for these belts is secured by springs 36 between the rear ends of the arms 28 and the plate 6, before mentioned.

To the inclined portion of the castings 24 (see Figs. 1 and 3) I attach a series of adjusts able brackets 37,with rolls 38 mounted in their upper ends. The series of belts before mentioned as operating in the grooves 20 of the pulleys 17 travel over the above-mentioned rolls and serve to operate, in connection with the belt 30, to feed the boxes down between the rolls and into their respective positions. The slack of this belt may be taken up from time to time by means of the adjustable construction of the bracket 37, before mentioned, as will be clearly apparent from Fig. Said brackets 37 are each further provided with a pair of guides 39, which extend rearward to either side of the belt and retain the same properly upon the roll, as will be obvious from Figs. 2 and 3 of the drawings. A second guideplate 40 is mounted in front of the bolts 21 and, with the guide-plate 31, forms the receivingtrough, which extends throughout the length of the machine and serves to deflect ICO ICS

the boxes downward in between the belts.

This plate is secured at either end by means of screws 41 to the casting 24, and the intervening portion of said plate is bent upward slightly to form a space between it and the and automatically moves said disks forward inclined portion of the casting 24 to permit the belt andpulley to freely pass therethrough.

The disks 18 are each provided with a frictional pawl 42, mounted upon a rod 43, secured to the end plate 6. Adjacent to each of thesepawls and secured'to said rod is a bracket 44, having a pair of arms straddling said pawl and a spring 45 interposed between said arm and pawl to force the latter downward against the periphery of the disk. These pawls impart a slight resistance to the disks, serving as a brake to prevent a too freerotation of the same, insuring their alinement one with the other, and prevent any backward movement. 3

In practice my machine would be set up with its rear end against a box-machine with which it is to work,sothat the boxes as delivered from the said machine would be fed into the trough of my machine lengthwise. With this'location the forward ends of the boxes would be thrust forward between the guide- plates 31 and 40 so as to strike against the adjustable stop 46 located in the trough, see Figs. 1 and 2 and6, whereupon said box would drop down upon the plate 40 and with the assistance of the plat 3l'be deflected in betweenthe belts. a

In Fig. 7 of the drawings I have shown a machine'adapted to take care of the product of a double-tube machine. This form of my in vention contains two sets of guide-plates or troughs side by side instead of one, as in-the other construction, one trough being adapted to feed the boxes between the rolls slightly in advance of the other, thus making it substan tially practicable for each-series of notches to take care of a box-as it is fed in.

In Fig.8 I have shown another slight modification, the same being adapted for shorter but wider boxes wherein a fewer number of cams and a stripper 24 which is located adjacent to the lower feed roll and com prises a plain vertical wall with a sharp top edge. In this view the use of belts is also entirely omitted.

Each of the forms of construction shown in these drawings is perfectly practicable, being to-day in operation, and consequently I do not wish to limit myself in the use of belts or any other details of construction of the apparatus.

The operation of my machine is as follows: Power is applied to the belt-wheel 7, which through its shaft and gear imparts a rotary movement to the series of pulleys upon shaft 12. From this shaft and through the gears 13 and 14 the small roll 15 is operated. This roll in turn operates its series of belts, while the pulleys upon the main shaft are likewise driving their series of belt's.- 'With this continuous and'rapid movement of the parts the boxes are successively dropped down in between the guides andbelts, striking the notches 23 upon the disks. As the box engages these notches it is straightened out until said box is grasped by the rolls, which compress and guide said box against the near side of the previously-stacked boxes. It will be apparent-that after the box passes through the rolls the outward edge leaves the notch in the cam of the disk and strikes the top of the table,where its further progress is retarded." I The-boxes are thus landed one against the other, the series being gradually shoved outward against the resistance of the block 47, as shown in the several figures of the drawings. This stack of boxes may be allowed to accumulate to as great a proportion as isnecessary to insure their proper drying before removal, the removal of said boxes being at all times effected from the outer edge.
