APPARATUS FOR THE PRODUCTION OF DESIGNS IN BAYER, MILLBOABD, VEGETABLE LEATHER SUBSTITUTE, AND LINOLEUM SUBSTITUTE.

Application filed December 9, 1922. Serial No. 608,007. I

. To all whom itmay concern Be it known that I, F REDERIC]; KATE, a

Production of Designs in Paper, Millboard,

reland, residing at Ashton-upon-Mersey, in-

the county of Chester, England, have m vented a new and useful Apparatus for the Vegetable Leather Substitute, and Linoleum Substitute (for which application has been filed'in Great Britain, No. 25,100, September 22, 1921), of which the following is a specification.

This invention refers t and consists of new or improved apparatus for carryingf out a process of producing inlaid pattern e ects in paper, millboard, vegetable leather substitute and linoleum substitute, the said process consisting in super-posing layers of coloured pulp or pulp material upon a foundation of pulp (which may be white or coloured) the several layers being amalgamated while moist, by pressure and drying,

into a single article. In my copending application, Serial No. 606,006, filed December 9, 1922, I have fully described and.

claimed the process of forming these inlaid pattern efiects.

According to the invention the improved apparatus consists of a machine of the millboard type in which the pulp is run into vats, in each of which is fixed a revolving wire gauze covered cylinder, which collects the pulp on its outer surface and carries it upwards to be taken off by an endless travelling blanket or felt pressed against the wire gauze surface of the cylinder by a couch roll.

The wire-gauze surface of the first cylinder is made in such a manner that while such cylinder, and if necessary, a number of succeeding cylinders, may have a plain wire surface to deliver to the blanket or felt a continuous sheet of pulp, the succeeding wire cylinders fixed in the direction of movement f the moving felt will have a non-continuous area of wire-gauze to pick up the pulp. That is to say a desi in wire-gauze, will run over the superficia surface of the cylinder which will pick up the pleted design will be taken off in like manner to the usual paper board.

Upon the accompanying drawings:

Flg. 1 illustrates a diagrammatic sectional elevation of a mill-board making machine constructed according to the invention.

Figs. 2, 3 and 4 illustrate plan views of the last three rollers shown in Fig. 1.

Fig. 5 illustrates a cross-section of a detail hereinafter described.

a, a a", a, are the vats for holding the of which revolves in the pulp and collects the pulp on its outer surface, and carries it upwards to be taken ofl'byan endless travelling blanket or felt a, pressed against the wire gauze surface of the cylinder by a small couch roll 01.

Assuming the pattern to be produced consists of coloured bands of three different colours the first vat a will contain the pulp for the foundation layer, and maybe white or coloured, whilst the other vats will each contain pulp of one of the predetermined colours.

The first cylinder a will be furnished with the ordinary continuous wire-gauze surface, and on revolving, willconvey to the felt 0 a continuous layer or sheet of pulp equal in width to the length of the cylinder, and as such layer or sheet is taken off by the felt, it will be carried forward by the felt past the other cylinders to the delivery end of the machine. Each succeeding cylinder 6 b, b will be slightly less in diameter than cylinder b and will be provided with a wire-gauze surface corresponding to the intended design, or a part of such design. In the example shown, each cylinder b b 7) "is providedwith bands of wire-gauze which stand away from the cylinder proper, the position of the bands on one cylinder registering with the intermediate spaces or non-gauze covered parts of the other cylinders, see Figs. 2, 3 and 4:.

'With the cylinders thus formed they each pick up bands of coloured pulp from their respective vats which are transferred t the foundation layer or sheet of pulp on the felt a in such position as to cause the final product to emerge from the machine in the results in the production of a single article having an inlaid coloured pattern.

The excess moisture is drawn from the pulp as it passes over the gauze-covered parts of the cylinders in the usual way.

The number of vats and cylinders With different coloured pulp supplied from different stufi' chests will depend upon the thickness of the material required and the number of different colours necessary to make up the design. In this way there may be two or more vats and cylinders for producing the foundation layer, and two, three or more for the coloured layers.

In the case of the cylinders carrying the design, or a portion of the design, any suitable mechanical device may be employed for the fixing of the Wire-gauze which expresses and produces the coloured design for each separate colour, one colour only on each separate cylinder. For example, the skeleton parts of the cylinders 6 b 6 before the wire-gauze is fixed on them, may be one, two or more inches of lesser diameter than the plain, Wire-gauze covered cylinders 6 The design may be traced out over the cylinder by thin bands 6 of suit able metal one, two or more inches wide, see

Fig. 5, fixed vertically on edge over the surface of the skeleton cylinder the wire-gauze being fixed across the upper edges f the upstanding bands of metal, with the necessary strengthening wires, or rods, etc., fixed un der the gauze and supporting it. The rest of the skeleton or frame work, of the cylinders may be covered with thick sheets of water-proof paper, made by the use of rubber latex, or by sheets of tin, wood and other suitable material to prevent the passage of the pulp and water into the interior of the revolving cylinders at such parts.

What I claim is Apparatus of the character described comprising a hollow cylinder, spaced bands extending from the surface of the cylinder and circumferentially thereof, means for securing strips of gauze to the bands Whereby the working surface is raised above the surface of the cylinder to produce the outline of a design, and a non-porous jacket surrounding that portion of the cylinder free from gauze.

In testimony whereof I have signed my name to this specification.
