To, all whom it may come wt:

Be it known that we, Lns'rnn P. WI'NcHEiv- 'BAUGH and LAWRENCE GENTILE, citizens of skilled in the art to which it appertains to 'make and use the same This invention relates to paper treating machines, and more particularly to machinesfor applying dye, stain or other coloring li uid to paper or similar material he primary objectof the invention is to improve the construction and mode of operation of machines for applying coloring liquid to paper and to devise a machine of this class upon which novel designs and ar tistic effects may be produced in an efficient and reliable manner With the above object in view an im-' portant' feature of the invention contemplates the provision, in combination with a receptacle for the coloring liquid, of a section of sheet fabric dipping into the coloring liquid in the receptacle through .which the liquid is withdrawn by capillary action for application to the paper. The coloring liquid may be applied to the paper by the contact of the fabric directly with, the paper.

In the present embodiment of the invention,

- however, the fabric is arranged ,to transfer the coloring liquid to the surface offa roll,

' andthe liquid deposited on the roll is thereafter applied to'the paper through the fen-v gagement of the roll-therewith. c

The coloring liquid isthus'withdrawn by the fabric from the container in a regulated amount as required for application to the aper so thatthere'is no excess liquid to orm blots or imperfections in the designs.

The provision of this feature also enables -wide va'riatio ns in the designs and color combinations to'be produced in an efiicient manner. a Other features ofthe invention consist in certain novel and im roved constructions, ar-

ements, and .com inations of parts herer described and particular out in the claims. the advantages of which .6 and is transferred therefrom to the y pointed.

rerun-TREATING momma will be readily understood and appreciated by those skilled in the art.

The features of the invention will be clearly understood from the accompanying drawings illustrating the invention, in its preferred form and the following detailed description of the constructions therein shown. In the drawings'Figure 1 is a view partly in side elevation andpartly in section of a port1on of a machine. embodying the invention; Fig. 2 is a plan view illustrating part of the mechanism shown in Fig. 1; and Fig. 3 1s a detail sectionalview taken substantially, on the line 3-3 of Fig. 2.

- The machine illustrated in the drawing has the same general construction and organization of parts as the. machine illustrated and described in the pending application of Lawrence Gentile, Serial No. 251,384, filed August 26, 1918., The machine is provided with a roll for the paper supply, with a pair of. drawing rolls for drawing the paperfrom the supply roll, and with a tens1on devlce through-which the paper passes 1 after leaving the first set of drawing rolls all as clearlyillustrated and described in mi application. After leavingthe tension device the paper, which is indicated at P in the drawing, passes over a series of cross bars 2 to a pair of

rolls

4 and 6, which cooperate to apply the coloring liquid to the paper. The

rolls

4 and 6 are provided with trunnions journaled; respectivel in bearing '

blocks

8 and 10, mounted to s ide in vertical 'clearly shown in'the drawing, passes under the rollg4 and then'between the rolls. The coloring liquid isvfirst applied to the roll as the paper passes between the rolls.

The coloring liquid is contained in a re,- receptacle 16. mounted between the uprights 12 and is transferred from the receptacle to the roll 6 by means of a section of sheet fabric 18, one end of which dips into the coloring liquid in the receptacle 1 6 and the other end of which rests on the roll 6. The fabric 18 is made of such material and is so constructed that the coloring liquid will be drawn relatively rapidly therethrough by paper mannena heavy cross bar is arranged to bear through gravitational action on the fabric. The bar 20 is mounted on the outer ends of rods 22 secured at their inner ends in a rotatable support 24 the ends of which engage in hearings in the uprights 12.

The bar 20 is thus pivotally movable toward and from the roll 6 and is held with considerable pressure against the fabric 18 by gravity during the operation of the machine.

To prevent the fabric 18 from being drawn from the receptacle 16 by the rotation of the roll 6, the bar 20 carries a series of projections or points 28 which are arranged to be embdded in th fabric. The receptacle 16 is provided with a trough 26 to catch the liquid which drips down the outer-face of the inner wall thereof.

The surface of the roll 6 as shown in the drawings is formed with elevations and depres'sions having any suitable form and arrangernent to draw the liquid as required from the fabric, and the fabric 18 thus contacts with and deposits the coloring liquid upon the high points on the surface of the roll. The coloring liquid is then transferred by the roll onto the paper in a design corresponding with the design formed on the surface of the roll. lit will be noted from Figs. 2 and 3 that roll 6 as illustrated is provided with a series of sharp pointed elevations extending in a general direction longitudinally of the roll or transverse to the direction of movement of the peripheral surface of the roll. Thus the projections on the roll receive not merely a thin surface film of the coloring liquid, but the liquid is drawn from the fabric in quantity sufficient to penetrate the paper and to spread from the point of 'application, giving a design without hard edges and producing very artistic effects. The roll t may have a smooth periphery if desired. In the illustrated construction, however, the surface of the roll 4 is also provided with elevations and depressions corresponding with those on the roll 6 so that the paper is mbossed in passing between the rolls. In actual practice steel embossing rolls such as are ordinarily employed in embossing pa er have been used.

ith the above construction a regulated quantity of liquid is withdrawn from the receptacle 16 and deposited on the roll 6 by the fabric 18 and is then transferred from .amount of coloring neaaaea the roll to the paper. The liquid is withdrawn from the receptacle by the fabric only as rapidly as it is deposited on the roll so that there is never any excess of liquid to form blots or other imperfections in the desi ns. 7

here it is desired to apply the coloring liquid to the paper only at certain points in the width of a strip the fabric 18 may be cut so that it engages the roll 6 only at certain points in the length of the roll. Two or more colors may be applied to the paper at the same tim by providin two receptacles for coloring liquids of di erent colors, and

two sets of devices for transferring the respective coloring liquids to the paper arranged so that the paper is carried successively past the same. The amount of the coloring liquid deposited on the paper may be varied by varying the speed of the

rolls

6 and 10. The greater the speed at which these rolls are rotated the less will be the liquid deposited on the roll 6 by the fabric.

en the fabric 18 becomes worn by long continued use, or when it is desired to change the coloring liquid to be applied to the paper, it is necessary to remove the fabric which is in use and to substitute therefor another section of fabric. Tn changing the fabric it is necessary merely to swing the bar 20 away from the roll 6, thereby disengaging the projections 26 from the fabric, and to lift the fabric from the 'rnachine. The -substituted section of fabric is then placed in position with one end within the receptacle l6 and with the other end resting on the roll 6, and the bar 20 is. then swung back into the position shown in the drawings to hold the fabric in .position.
