HENRY S. OROOKE AND LEWIS OROOKE, OF NEW YORK, N. Y.

MANUFACTURE OF METALLIC FOIL.

SPECIFICATION forming part of Letters Patent No. 227,496, dated May 11, 1880..

Application filed September 8, 1879.

To all whom it may concern Be it known that we, HENRY SUYDAM ORooKE and LEWIS OROOKE, both of the city,

, in the Art of Manufacturing Metallic Foil, of

which the following is a specification.

Our improvements may be divided into two principal divisions, the first of which comprises the new manufacture in its different styles, and the second of which comprises the processes by which the same is made.

In order that both parts of our invention may be fully understood, we will proceed to describe the mode in which we have produced our new manufacture and the characteristics of the latter. v

The material used, by preference, as a basis for the manufacture is tin and its alloys with lead, and the material is reduced to the condition of foil by the customary means and process employed in the manufacture of rolled burnished tin-foil, which means and process, being well understood, need not be described.

We prefer that the surfaces of the foil shall be commercially pure tin, while the body or core is of lead, or of an alloy of tin and lead, the core and surfaces being'welded together in the process of rolling.

According to one mode of manufacture, the metallic foil, when produced as above stated, is subjected to the action of a pair of hard rollers, the surfaces of the bodies of which are etched or matted, and the two rollers are held together with sufficient force to mat the tin foil subjected to their action, the practical effect of which is to impart to the tin-foil a dead-white surface resembling frosted silver.

The matting-rolls which we. prefer for this operation are of steel or of chilled iron, and their bodies are first ground true, and are then etched by means of weak muriatic acid, or some other acid or mixtures of acids that will effect the desired result. The foil is stripped from the surfaces of the matting-rolls, and is then colored or printed, by preference, with a printing-roller having the design formed upon its surface. As the surface of the foil isa matsurface, but smooth or without appreciable indentations, the color or printing-ink takes readily to the surface, and the printing is effected as readily as upon paper. The printing may be done while the foil is in the web, or

the foil may be cut into sheets of greater or less size, which may be printed by means of either a cylinder-press or a flat press.

After the coloring or printing is completed and dry the printed sheets offoil are embossed, the preferred mode of doing this being to submit the printed web of foil to the action of a pair of embossin g-rollers, the surfaces of whose bodies are the counterparts of those of the foil to be produced.

According to another mode of proceeding, We color or print the foil in the burnished'condition in which it exists when the metal has been reduced by rolling in the usual manner, and after the printing is dry we emboss the printed foil, as before mentioned.

The distinguishing characteristics of both modes of proceedingare that the foil is colored or printed before its surface is indented by embossing; hence the coloring-matter is applied; to a flat surface either burnished or whitened, and the article produced is characterized by the peculiarity that the ornamentation produced by embossing indents the colored surface. (Jonsequently the hollows or indentations of the foil are as well printed as the projections, which result is not practicable when the foil is printed after the embossing operation has been effected.

' As before stated, the foil may be printed or colored in the web and cut up subsequently or may be printed in sheets of greater or less size, and the sheets may be either left in the sizes in which they are printed and embossed or cut up into smaller sizes, or the material may be sold in the web and cut up by the user.

If the surface of the foil is matted before it is printed, the parts of the foil not printed present a silvery white surface as a background ferent manufacturers of the articles to be wrapped, may be embossed in the foil in connection with a great variety of printing or coloring, while the foil, being metallic, is impervious to water, air, and grease.

We claim as our invention- 1. As a new article of manufacture, ornamental metallic foil having its surface matted,

' colored, and embossed in a pattern, substan- 4. The improvement in the art of making metallic foil, substantially as before set forth, comprisingthe following operations, viz: first, the printing of the foil; second, the indenting or embossing of the surface of the article, the said operations being performed in the order in which they are above specified.

W'itness our hands this 5th day of September, A. D. 1879.

HENRY SUYDAM OROOKE. LEAVIS OROOKE.
