- To all whom, it may concern;

Be it known that I, FREDERICK WALTON,

engineer, a subject of the King of Great Britain, residing at 114 Holborn, in the city of London, England, have invented an Improved Process of and Apparatus for Painting and Coloring Lincrusta, &c;, of which the following is a specification. 1. This invention has reference to an improved method of and apparatus for paintmg or coloring lincrusta and like embossed materials.

I-Ieretofore when it has been desired to produce lincrusta in two .colors or shades it has been customary to first paint the embossed surface by hand and to then remove, also by hand, the wet aint from the raised portion of the embosse surface, so as to eX- pose at such places the original or body color of the lincrusta. This method of removing the paint from the lincrusta has involved a considerable expenditure of time, labor, and materials, which it is the object of my present invention to avoid.

According to my invention the lincrusta or like embossed material, possessing the desired body color or tint, has applied to its surface by mechanical means paint or color of the required shade, which is subsequently removed by mechanical means from the raised parts of the embossed surface, whereby the lincrusta possesses two colors or shades, one being in the de ressed portion of the attern and correspon ing with the color or shade of the paint applied thereto and the other being on the raised portion of the pattern and corresponding with the color or shade of the original or body color of the lincrusta.

A suitable form of apparatus for carrying my invention into practice comprises a rotary drum or other travelling support for the embossed material, a paint or color applying device, and two or more adjustable rollers which are adapted to bear against and wipe the raised portions of the surface of the lincrusta from which the paint or color applied by said device is to be removed.

The paint or color ap lying device may com rise a movable trough or other container for t e paint or color, a roller partially immersed in the paint and adapted to apply the paint or color to the embossed surface of the lincrusta, and a rotary brush adapted to distribute the paint or color, so that it will cover both the raised and the depressed portions of the embossed surface.

In order that my said invention may be clearly understood and readily carried into effect, I will describe the same more fully with reference to the accompanying drawings, in which Figure 1 is a side elevation, and Fig. 2 an end view of a machine suitable for my purpose. Fig. 3 is a detail plan of the paint or color applying device; and Fig. 4 is a crosssection of the same, taken on the line 1 1 of Fig. 3.

A is the rotary drum, fixed upon a shaftA which rotates in bearings A.

B is the paint or color trough or container, B the paint-applying roller, and B the rotary brush for distributing the paint, as

aforesaid.

C C are the adjustable rollers, and D D are doctors or scrapers for said rollers, having troughs D.

The mechanism for rotating the drum A comprises a worm-wheel A mounted upon the shaft A and gearing with a Worm A on the shaft A which is driven by the pulley A The rollers C C are preferably made from printers roller composition or other suitable pliable or elastic material and have spindles C 0 which at each end are rotatably mounted in bearing-blocks 0 C These blocks are supported in guides O C, having springs C C for imparting to the bearings a certain amount of flexibility or resiliency. Screws C C, connected with the said blocks, enable the latter to be moved up or down in the guides C C, so as to adjust the position of the rollers C C with respect to the surface of the lincrusta. Each spindle C of the rollers C has at one end a gear-wheel C engaging with teeth A on the drum A, by which the said rollers 0 receive their motion. The doctors or scrapers D D are held in such a position with regard to the rollers C C that the paint collected by the doctors from the rollers will enter the troughs D D.

The rotary brush B is driven by a toothed pinion B ,'which gears with a toothed wheel B, mounted on a fixed stud B said toothed wheel forming part of toothed pinion B, which gearswith the aforesaid teeth A of the drum A. By this means the brush B is rotated in a direction opposite to that of the against the under side of the trough, is provlded.

The lincrusta is guided to the machine by a roller O and is conveyed, by means .of the drum A, to the paint or color applying device. The painted lincrusta then passes under the successive rollers C C, which remove the paint from the raised portions of the surface of the lincrusta, the paint thus removed being transferred from the rollers to the troughs D by the doctors D. I

A machine constructed in accordance with my invention may in some instances be advantageously employed for merely applying paint of a particular color or shade tothe lincrusta, in which case the adjustable rollers C would be brought out of contact with the surface of the lincrusta, so as to avoid removing the aint thus applied.

hat I claim, and desire to secure by Let-.

ters Patent of the United States, is

1. In the manufacture of painted or colored lincrusta and like embossed material, the combination with a rotary drum for the embossed material, of a device for applying paint or color to the entire embossed surface of said material, a series of resilient wiper-rollers for removing from the raised portions of the embossed surface the said paint or color, means for adjusting the position of said wiper-rollers with respect to the embossed surface, and

means for revolving said wiper-rollers from said rotary drum substantially as described.

2. In the manufacture of painted or colored lincrusta and like embossed material, the combination with a rotary drum for the embossed material, of a device for applying paint or.

color to the entire embossed surface of the said material, a series of comparatively soft wiper-rollers for removing from the raised portions of the embossed surface, the said paint or color, means for adjusting the position of said wiper-rollers with respect to the embossed surface, and gearing for revolving said wiper-rollers from said rotary drum substantially as described.

3. In the manufacture of painted or colored lincrusta and like embossed material, the com bination with a rotary drum for the embossed material, of a device for applying paint or color to the entire embossed surface of the said material, a series of comparatively soft spring-controlled wiper-rollers for removing from the raised portions of the embossed surface the said paint or color, means for adjusting the position of said wiper-rollers with respect to the embossed surface, and toothed gearing for revolving said wiper-rollers from said rotary drum substantially as described.
