COLOR-DEPOSITING APPARATUS FOR PAPER-MAKING MACHINES.

Application filed'octooer 7, 1926. Serial No. 139,972.

This invention relates to the art of wall paper: manufacture, having reference more particularly to a type of wall paper generally known as tilfany paper, wherein the color effects are incorporated in the paper during the process of manufacture of the latter, as distinguished from subsequent printing, by means of a liquid color, or a number of different liquids colors, sprayed onto the surface of the Web during the travel of the latter on the Wire screen in machines of the Four drinier type.

The color spraying apparatus of the present invention is designed to produce a paper having a variegated or mottled appearance wherein the different colors run into and are blended with each other on the surface, thus creatinginthe latter regions of different colors which, however,are not sharply defined but, as stated, overlap and blend or shade into each other, creating a variegated cloud effect. i c

Among the objects of the present invention are to provide an improved and simplified chrome blast apparatus adapted to spray the liquid color vertically onto the surface of the web, to provide such an apparatus wherein the width of the spray striking the web may be varied through vertical adjustment of the downwardly directed spraying nozzles or guns relatively to the surface of the web, to provide such an apparatus wherein the spray may be delivered intermittently, rather than continuously, and during its delivery may have a reciprocating movement relatively to the web and crosswise of the latter, to provide an improved automatic valveactuating mechanism for the sp 'ay guns, and to provide an apparatus that may be adjusted to change'the color scheme by atl'ording different relatively timed. movements of the valve-actuating and controlling devices of different sprayers or groups of sprayers.

Still. other objects and attendant advantages of the invention will be apparent to persons familiar with the art as the same becomes better understood by reference to the following detailed description, taken in connection with the accompanying drawings, wherein I have illustrated one practical em bodiment oftlie principle of the invention, and. in which i Fig. 1 is a side elevation of the color ch positing apparatus and its driving mechanism, showing the wire screen and paper web carried thereon in cross-section;

Fig. 2 is a top plan View of the sprayers and their actuating devices;

Fig. 3 'is a vertical transverse section taken on the line 33 of Fig. 1;

Fig. 4 1s a detail side elevation of one of the sp 'aying guns and its actuating mechanlsm; and

Fig. 5 is a diagram, illustrating the general order or arrangement of depositing the several colors on the web, and the relation of the actuating cams of the sprayer guns thereto, but without showing the overlapping and blending of marginal regions of the variously colored spots.

Referring to the drawings, designates the usual wirescreen'web conveyor of a Fourdrinier machine, and 11 designates the end roll of the machine over which the wire screen passes and by which it is driven. 12 designates the paper web which is delivered through the usual flow box to the screen, spread thereon by the usual slices, and drained by the usual suctionboxes. These parts of the paper machine are not illustrated as they form no part of the present invention.

On opposite sides of the screen 10' are erected on. suitable foundations 13 four rec tangularly disposed columns 14, two on each side; and between the columns of each pair is a bracket 15 formed at its ends with sleeves 16 slidably mounted on the columns 14 and secured in adjusted position by set screws 17. On each of the brackets 15 are mounted a pair of pedestals 18 (Fig. 3) formed on their adjacent sides with hearing bosses 19 (Fig. 1) in which. are slidably mounted a pair of parallel rods 20. The columns 14: above the rods 20 are rigidly connected and braced by longitudinal angle bars 21 and transverse angle bars 22.

Mounted on each of the rods 20 are spaced clamp collars 523 (Fig. 3), and in lateral bosses 24 on the outer sides of said collars are mounted a series of sprayers or guns designated as an entirety by 25, each terminating at its lower end in a spray nozzle 26. Supported oncross-bars 27 resting on the horizontal limbs of the angle bars 22 are a s ri :in shown as four, of color mani l l v A an, each cquipperlwith overlying return flow manifold 29. Tapped into the lower sides of the manifolds 28 are faucets 30 each equipped with a valve 31, and de pendingfrom said faucetsare hose 32 leading downwardly into the Sprayers 25. In the arrangement shown, the hose from a pair of color manifolds on'one side lead into a..ternate sp'rayers in one row, and the hose 82 from the two color manifolds on the other side lead into alternate sprayers the other row, so that the sprayers of one row deliver two colors in alternatiop, arrangement and the sprayers of the other row also deliver two colors in alternating arrangement. suspended from the rods 20 as by loop hangers 33 (Fig. 1), or otherwise suitably supported, are a pair of compressed air n'ianifolds 3%, from which hose 35 also lead into the several sprayers. Where the compressed air manifolds are suspended from the reciprocating rods 20, the open ends of the air l'nanifolds 3d are connected to a compressed. air supply pipe 36 by flexible hose 3'? of suflicient length to accommodate the reciprocating movements of the COHlPl'GSSBLl air manifolds.

Rigidly mounted in seats in the upper ends of the pedestalslS' are a'pair of bars 38 each formed on its upper edge with a group oi uniformly spaced peak cams 39; the cams of one bar being preferably offset substantially midway of the peaks of the other bar. 611 each of the collars 28 is an upwardly extending' arm 40 terminating in a laterally offset vertical fork 41 that straddles and extends slightly above the cam peaks 39 of the bars 38 The limbs of'eaeh fork ll are themselves vertically slotted to receive a shaft 42 on which is journaled roller 43 riding on the upper edge of the cam bar 38. The ends of the shaft 42 overhangthe limbs of the fork, and from their overhanging ends is suspended a ll shaped link ll carrying 011 its lower end a hook d5 that is engaged with a clevis 46 that, in turn, embraces the trigger d7 of the sprayer gun, the raising of the trigger opening a valve in the gun which perll'llllS the sudden discharge of the liquid color and r the air blast furnished from the compressed air manifolds -l-l. As the sprayer gun herein shown is old' and well known and no novelty is claimed therefor, the structural details thereof are not herein snown. It may be noted, however, that the volume of the blast may be adjusted by turning an adjusting valve 48 normally locked in set position by one ormore nuts 49. From the foregoing it will be seen that as the rollers 43 ride over the cams 39, the triggers of the guns will be suddenly raised, permitting a charge of colorin g liquid to be sprayed directly downwardly onto the underlying web of paper.

The rods 20 may be reciproeated in suitably timed relation to the travel of the paper web by mechanism such as that illustrated in Figs. 1 and 2, as follows: 50 designates a main drive shaft carrying at one end a spur gear 51 meshing with and driving a spur gear on the shaftof the end roll 11. Keyed to the shaft 50 is a sprocket wheel 53 which, through a sprocket chain at, drives a sprocket wheel 55 fast on a countx-rshaft 56. This latter, through bevel gears 57 and 58 drives a shaft 59 journaled in bearings (50 on a base plate (31 SHPLIOITiMl on a pier (372. Sn shaft 59 are sprocket wheels 63 which, through sprocket chains (31, drive. sprocket wheels 65 fast on a pair of endwise aligned sh: (i6 journaled in bearings 67 on standards (38 on the base plate 61. (in the inner opposed ends of shafts (36 are crank discs (3!) carrying wrist pins "(0 herein shown as set 180 apart and having equal throws. Pitmen 71 connect the wrist pins with the ends of the rods 20. With this {lli.'?lI1 {'0lllt.T1t, the rods 20 are sin'iultaneously r'eciprocated to equal extents in op posite directions.

F ig. 5 illustrates diagrammatically the manner in which the various colors are sprayed on the surface of the paper web. Assuming that the latter is traveling in the direction indicated by the arrow, at a point in the travel of one of the rods 20 (herein indicated as at the end of its travel) the cams operating the guns carried by said rod serve to discharge the latter, depositing on the paper web the first, third andv fifth rows of color spots, the spots in each row presenting alternately the two colors discharged by alternate sprayers. Simultaneously the spots indicated by the second, fourth and sixth rows are deposited by the sprayer guns mounted on the other red 20, the spots in said rows also alternating between the two colors discharged by said second row of sprayer guns. Atthe top of Fig. 5 are shown the relative positions of the two cam bars, when the colors are deposited in the manner above described. In this diagram the color spots are shown as sharply defined in order to illustrate the principle of operation; but it is to be under stood that in actual practice the marginal portions of the spots overlap and blend to a greater or less extent depending upon the vertical adjustment of the sprayer guns above the surfaceof the web. lilanifest-ly, the hi gher the guns are set, the greater will be the diameters of the spots, and the greater will be the extent to which they will overlap and blend into each other.

The relative positions of the spots, and the ultimate coloring effect or color scheme can be widely varied by' either changing the relative positions of the actuating can'ls or hv varying the reciprocating relation of the rods 20, or both; for instance, the wrist pins 70 on the crank disc 69, instead of being set one hundred and eighty degrees apart so as to effect simultaneous travels of the two rows of sprayers in opposite directions. may he set ninety degrees apart so as to effect a syn chronous reciprocation of the rods. Also, the speed of operation of the sprayer guns relatlvely to the speed of travelof the paper web 'may be varied as, for instance, by providing on the hub of the cam drive sprocket 55 a sprocket of a different diameter, such as the smaller sprocket shown at 55, the driving sprocket 53'being shittable along the drive shaft to register with either of the

sprockets

55 and 55. These adjustments, together with the vertical adjustability of the sprayer guns, render the apparatus very time ible, and make possible the production thereby of widely varying color effects when using a single assortment of colors.

I have herein illustrated and described one simple and practical embodiment of the principle of the invention which, in p notice, has been found to satisfactorily effectuate its stated purposes and objects; but manifestly the details of structure and arrangement may be considerably varied from those shown without changing the principle or sacrificing any of the advantages of the invention, and hence I do not limit the latter to the particular apparatus herein presented except to the extent clearly indicated inv specific claims.
