To fz/ whom, it may concern: Y Y' Be it known that I, JAMES G. BEATTIEI e.

uitleen oi' the limited States, residing at York, borough of Brooklyn, in the County ofV Kings and State of New York, have. invented a new and useful Machine forApplying Adhethe following is a specification. Y

This invention relates generally to seating the surfaces of sheets of peper, cardboard, and the like and also other sheet materials and blanks made therefrom with glue or other adhesive to adapt the sheets or the blsnks to be used for eoveringit the objects or articles, those sheets or blanks being coated with the adhesive preparatory to und applied while the adhesive 1s wet and the material soft end pliable.

Specifically the invention hss reference to o machine for applying adhesives to pe er covers for peper or pasteboord boxes winch are out out from sheets of comparatively thin, soft, and pliable paper and shaped inthe eutting;r to odapt them to form the oevers.

Paper or pssteboard boxes are covered either with tight-Wrapped or loose-wrapped covers. Nhenacoverforatight-wrap )ed box is en'ipioyed, the surface which is stuelt to the1 box is completely covered with the adhesive,

so that every part of it will adhere tightly and smoothly to the entire surface and the edges of the box; but when prepared for s loose-wrapped box the adhesive is applied only st end neer the edges in coniperstiveiy narrow lines, so that when the cover is nppliod the edges only adhere, the rest of' the cover being left loose or nnattached, thus giving o less rigid and curved or convex epeerenoe to the surface of the sides, ends, and' liottoni, which is much desired in boxes for rertein classes of trade. Applying adhesives to coversrfor tight-Wrapped boxes has'be'err'" done by hand-labor from time imnernorial; but this inode is slow, tedious, expensive. end more or less imperfect and unsatisfactory he,m rause of the uneven distribution of .the adhesive. To secure the cover properly,Y s. more pollici@ of the adhesive is all that is nee-es sary, :1nd this should be leid on snooth', oven, end oi' uniform thickness. ll' this is not rione', the rover will not lio list and smooth? and it is ieilo to blister, whereby the finish of the box is spoiled and its appearance rendered unsightly. Covers for loose-wrapped boxes have the lines of adhesive spplied by means of eV stamp provided withV impressionisti?- Yferries of the proper Width end shape to apply Ythe' adhesive to the edges of the blank ond he stamp being supplied with the adby pressing it against e surface on 'vv roh the adhesive is spread in e more or less YYYthinlayer, from which it trikes up suioient for the edges of the Cover, to which it is transferred by means of the stamp. Owing to the fact that the sheet of paper or the blank becomes soft when Coated with the adhesive, it has o tendency to cling to the adhesive-sppiying devioe and also to curl up, more or ess, along the edges. It has been found difficult to apply the iadhesive by mechanics-l means. ln machines which have been oonstrnoted for the purpose heretofore it has )een found necessary to apply the adhesive in stripes by Ineens of staggered rolls srranged in parallel shafts, by which the ble-nk is alternately striped with the adhesive as it through the two sets of rolls soecessively. In this construction two feed-rolls sro required to cooot with the two sets of staggered gluing-rolls, and as Vthese gluingroils ere spaced more or loss nnevenness is if'nperted to the loyer of adhesive at the junotion of the adjoining stripes, which being leid on alternately, the adhesive is liable to be pnshed out from under the. ends of 'the rollsY and form more or less of e ridge where the edges of the two stripes meet. Furtherrnorelg'ifhe blank being liable to erihere'to the gluing-rolls after the adhesive is applied in Y. the nieehinos heretofore constructed it is nocessery to provide separate supports for the bisnk while moving through the two sets of rolls and receiving the adhesive and for lifting or, in s sense, stripping its forward end Yfrom the rolls. These. supports being staggered like the rolls, there is a break at the eenterwbetween the two sets, and one set has to be fixed n slightly higher plane thun the other to prevent the blank catching as it moves over tho supports.

The object-of my invention is, rst, to produce a. simple, prsotiesl, and efficient machine for ripplving adhesives to sheets of psper and olsnhs for box-covers, &o., Inode therefrom; seoonilVs to regolate the quantity of adhesivo transferred to the gluing-roll end from that to the snrfnoe of tho peper or blank in order to restriot the coating to s. this pellog licle, and thus prevent the application of a greater quantity of the adhesive to the paper or blank than is requisite for sticking it to the surface to which it is to be applied, and thereby prevent blistering and unevenness of the cover of the box or other object; third, to make it practically impossible for the forward movement of the adhesive-coated paper or blank cover being intercepted or restrained by the means which su port the paper blank after passing the bite of) the gluing and feeding rolls; fourth, to apply the adhesive to the entire surface of the paper or blank by means of a single roll, and thus insure the uniform and complete application of the adhesive in a thin unbroken ellicle to the entire surface; finally, to combme in a single machine means for applying an adhesive to one surface of a sheet of paper or other material or a blank cover made therefrom and means for supplying adhesives to a moving surface from which to transfer the same by means of a stamp to a sheet of paper or a blank box or other cover or article made therefrom in broken or continuous lines and to regulate the amount of adhesive transferred by the stamp, so that a thin ellicle only will be impressed upon the artic e by the stam The invention wifi first be described in connection with the accompanying drawings and then particularly pointed out in the claims.

Figure 1 represents a side elevation of the gluing machine. Fig. 2 is a planl of the same; Fig. 3, a sectional side elevation showing the rgearing, the section being taken on line X of Fig. 1. Fig. 4 represents a front end elevation of the operative parts of the machine above the frame. Fig. 5 represents a vertical longitudinal section of the machine, taken on line Y Y of Fig. 2 and drawn to a larger scalethan the plan.

Referring to the drawings, A A designate the side members of the machine, which are connected together by transverse members (not shown) at the ends and at intermediate points, so as to form a strong and steady support for the operative parts of the machine. At about equal distances from the ends of the frame there are transverse beams B B, securely bolted thereto.

C is a tank that rests upon and is fastened to the beams B B. When the adhesive is used hot, as is the case with glue, means are provided for heating the tank and contents;

ut as cold adhesives can also be used for some purposes the heating attachments may be omitted from the tank. The means here shown consist of a steam-pipe D, fitted in the tank. A branch aof the steam-pipe is passed through a glue-tight joint in one side of the tank and coupled to a pipe c, that leads to a source of steam-supply, a valve being placed in this pipe to cut oil' thc steam when necessary. Anothcr branch li is also passed through a glue-tight joint in another side of the tank and connected with a return steampipe. (N ot shown.) l/Vhile steam is preferred for obvious reasons, other means of heating may be substituted for steam, if desired. The bottom of the tank is also fitted with a draw-off pipe d, provided with a cock e for discharging the contents of the tank when necessary for cleaning, changing the adhesive used, and other reasons.

The frame supports housings 1 1,connccted with the frames opposite the ends of the tank. These housings are each provided with openings 2 3 in their sides and at the top with a slotted opening 4. These openings and slots are provided to receive the bearing-blocks of the fountain gluing and feeding rolls hereinafter described.

At the front end of the machine there are journal-bearings 5 5, formed bypillow-blocks and caps, in which a driving-shaft S is supported, that carries the driving-wheel W' and a sprocketswheel 6.

7 7 are standards bolted to the frames at the rear end. The upper ends of these stand ards are slotted to form bearings 8 8 for `the journals of the drum 9. A similar drum 1() is supported between thehousings at the rear on a shaft journaled in bearing-blocks 11 11, held in openings 12 in rear projections of the housings. The bearing-blocks rest on springs 13 and are held down by means of adjustingscrews 14. A belt 15 (preferably, but not necessarily, made of rubber) is placed on the drums 9 10. A table 16 is connected with and supported under the upper side of the belt by vertical supports 17 17 18 18, bolted to the frame. This table supports the belt when pressure is applied to it for a purpose which will be referred to farther along in the specification. Uver the belt there is a roller 1Q, the journals of which are supported in slotted bearings 2() 20, bolted to the table outside of the edges of the belt and above the standards 17 17. The roller 19 rests upon the surface of the belt and by its weight it distributes the adhesive thereon evenly and uniformly, and if the supply carried to the belt is greater than is re uired the roller scrapes or rolls back the re undant adhesive and limits the thickness of the same on the surface of the belt to a thin pellicle. The roller 19 being of solid material, brass bv preferenee, 1t bears upon the belt with sufficient force to cause it to be rotated b v friction, it not being geared to the driving mechanism.

The ductor or fountain roll 21, gluing-roll 22, and feed-roll 23 are mounted on shafts 24 25 26, respectively, which are journaled in bearing-blocks in the housings. The 'ournals 27 27 of the ductor or fountain rofl are supported in the bearing-blocks 2S S in the openings 2 in tluI housings, the journals of the ygluing-roll aro supported in lluI bearing,"- blocks 29 in thi` openings in thc housings, these blocks resting on the adjusting-srreus IOO ductor or 295i, and the iournals of the feed-rolls are sup- Eorted in the bearing-blocks 3() in the slotted eax-ings on the adjusting-screws 36a. The

fountain roll, gluing-roll, 'and feeding-roll are eared together by means Vof toothed Whes 3l 32 33 on the respective' shafts. Behind and in contact with the fountain-roll there is a scraper or supply-regulat- V ing roll 34, mounted on a shaft 34, journaled V.ICI

in the bearing-blocks 35 in the openings 36 in the rear extensions of the housings, and in iront bearing against the gluing-roll there is a similar scraping or supply-regulatinff roll 37 mounted on a shaft 37", journalei bearing-blocks 3S iniopenings 39 in the front extensions of the housings. Vhe function of roll 34 is to sera e 0H the redundant glue brought up by t e fountain-roll from the tank. Owing to the viscosity of the glue, the fountain-roll takes up a much greater quantity or a thicker layer than is required; but the supply-regulating roll 34 by rotating against and in close contact with the loun-Y tain-roll at a greater speed and in the op osite direction scrapes, rolls,` or presses o t e redundant #lue and reduces it to a com 'aratively thi-'n layer.

Wine hears against the thickness of the layer of glue taken by the gluing-roll from the ductor or fountain roll by scrapin rollinu', or pressing it olif the surface thereofg and reducing it to a very thin pellieie, which or e part of which is transerred to the surface of the peper or blank in a thin layer or pellicle, which is sufficient to cause the paper or blenk to adhere to the surface to which it is applied. The pressure on the rolls '34 37 is regulated oy means of the screws 39 4U, which are passed through cap-plates 41 42, respectively, and contact with bearing-blocks 35 37. By ineens of the pressure-regulating screws the quantity or thickness of the glue-on the rolls can he accurately controlled.

The surface of the fountain-roll is made of brass preferably, which is placed ou a core of iron or steel. The su ply-regulating rolls 34 37 and the feeding-roll) 23 arernade of iron or steel. The vskiing-roll consists of a rubber cylinder placed on a metal core. The rubber cylinder 1s provided with parallel circumferential slits e3 cut into the rubber at regular intervals from end to end and to the depth of something less than half the thickness of the walls of the rubber cylinder. At opposite sides of the gluing-roll there are bars 44 44, having tenons 45 on their ends, which i'lt into slots 46 46 in the front and rear extensions of the housinos, and thus support the hars horizontally incline with the top of the roll.

opposite the gluing-roll Similarly, the rol 3?,

sides ofthesc hars and their tops'are squared to form flat surfaces 47 48 at right an fles to eachother. The vertical sides 47 of t rese hars have tap ed holes 4,9 in them, which are spaced so t ist in thethe gluing-roll, reduces TheYY their centers are in line with the slits Y473Y Y the gluing-roll. These holes are tteil 'ith screw-pins 56. Wires 51 are insert-odin the slotsj43, and their ends are carried across the horizonta-l-at surfaces 48 48 of the twobars and dor'rnagainst the rear sides, Wiiere'tliey are connected with or held by the screw-pins 50. The Wires are drawn tight through the slits in the gluing-roll, and they form the support for the blank when moving from the gluing-roll after the glue is a plied. At the saine time they are of such eness that the sides el the slits, particularly thepart thereof ahorre the wires, close together over the wires, `whereby the surface in the bite of the Vgluing and feeding rolls is unbroken and the glue is laid on the entire surface of the blank uniformly and evenly.

vThe shaft of the roll 34 carries a pinion 52, which meshes with the toothed Wheel-31 on the'shaft of the fountain-roll, and the shaft of thefroll 37 carries a pinion that meshes with the toothed wheel Sgen'the shaft of the gluing-roll. These pinions ere niueh smaller than the Wheels the mesh with, and the rolls consequently are riven at a much higher speed than the fountain-roll end the gluingroll. The shaft of the belt-drum 10 also carriesia inion 54, which meshes with the toothed wheelrhn the shaft. of the fountain-roll, the belt l5 heilig thereby driven lfrom the toothed Y Wheel 3 The ductor or fountain roll is driven y means of a sprocket-chain 55, running on t e sprocket-Wheels 6 56.

The machine is constructed and-'intended to be used for e plying en adhesive to the entire surface o a hlank-say, a box-cover blenk-ior a tight-ivre. perl box, .and itis also designed and intende to be used for ap lying glue to the edges of such blanks W en theysre to he attached to the box by the edges-only and form what is known as a loose-Wrapped box. To cost a blank cover for a tight-wrapped box with the adhesive a pad of covers, with or without a stiller card on to Ythere is no break in the costing of glue laid on the surface of the blank; lThe pad asses through in a horizontal position and t le operator catches it, taires it u and removes the bottom blank, to which t 1o glue has heen epplied, lays another ble-nii on the bottoni of IDO the bottom blank end spplies" a the pad, and repeats the operation. The coated blank being softened and made very pliable by the wet adhesive applied to its under surface, it would adhere to the roll were it not that as it is moved by the pressure of the two rolls its forward end after passing the bite of the roll instead of being ermitte to remain on the gluing-roll is hel or lifted up by the wire supports, or, in other words7 stripped off the roll. so that it moves away from the roll horizontally and is freed therefrom. If a blank is to be glued for a loosewrapped box, this is done by means of a stamp applied to the thin pellicle of adhesive on the belt 15. This belt, 1t will be observed, rotates in contact with the fountain-roll above the regulating-roll 34 (see Fig. 5) and takes the glue therefrom in the same way as the gluing-roll takes it from the fountainroll. The stam is made up of a number of parts correspon( ing to the parts of the blank to which the glue 1s to be a plied, and it is ressed a ainst the top of tfie belt over the table 16 or the urpose of taking the glue therefrom. The Iblank is laid on a flat surface, and the stamp being transfers a thin layer of glue to the same in lines corresponding to the shape of the face of the stamp.
