PROCESS OF METAL ORNAMENTATION.

SPECIFICATION forming part of Letters Patent No. 663,624, dated December 11, 1900.

Application filed April 23, 1900. serialNo.13,887. (No specimens.) A

To all whom it may concern:

Be it known that I, WILLIAM A. DAY, acitizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, haveinvented a new and useful Improvement in Processes for Ornamenting Metal Goods, of which the following is a specification.

This in vention has reference to an improved process for ornamenting metal by embedding blanks, strips, or ornamentally-shaped pieces of metal or other material into the metal of the article or the blanks of which the article is to be fashioned, so as to produce the appearance of inlaid work.

In ornamenting metal by inlaying, recesses haveto be cut into the metal surfaces into which metal differing in color or quality is fitted and secured.

In the production of analogous metal ornamentations, such as damascene,niello,or bidri decorations of metal, grooves or recesses have to be cut, into which the metal or compositions of metals are embedded and secured. The processes by which these ornamentations are produced are slow and costly.

The object of this invention is to decorate metals and metal goods having all the beauty and appearance of inlaid and similar metal goods ornamented by the older processes by a cheaper process, producing a more durable and better quality of ornamentation.

The invention consists in the successive steps of the process whereby the ornamentation is embedded in the metal and the surface ornamented, as will be more fully set forth hereinafter.

Figure l is a plan View of an ornamental border designed to be embedded in the surface of a plate to be formed into the required article. Fig.2 is a plan view of a plate on which the ornamental border is secured. Fig. 3 is a sectional View, on an enlarged scale, of a part of a plate, showing parts of the ornamentations secured to the same. Fig. at is a sectional view of part of a plate,showing the surface of the plate and the ornaments covered with metal deposited on the same. Fig. 5 is a sectional view of part of a plate, showing the ornaments embedded in the surface of the plate.

I have illustrated the steps of my improved process in the drawings as they appear when an ornamentation of metal dilfering in color or texture from the metal of the surface to be ornamented is embedded in a sheet or plate of metal adapted to be formed into the required article. The process is also applicable to the ornamentation of the formed-up article. In the drawings, a indicatesthe ornamental blank whichit is desired to embed into the surface. This blank a may be stamped, out, or otherwise formed of a sheet of metal, or the blank may consist of any desired number or parts of smaller blanks of the same metals or a variety of metals differing in color, texture, or otherwise. The blank a or blanks a a are secured to the surface of the plate 5 by solder or by sweating. When a large number of small pieces combine to form the ornamentation,it is more convenient to secure the same by the use of solder, while larger parts are preferably secured by subjecting the plate I) and the ornamental blank a to sufficient heat to secure them together by sweating.

Fig. 1 illustrates the first step, and Figs. 2 and 3 the second step, in which the ornamentation is secured to the face of the plate I). This ornamented plate is now cleaned and prepared to form the cathode in an electrolytic bath, in which the desired thickness of metal 0 is deposited over the surface of the plate and the ornamentation, as is shown in Fig. 4. The plate is then removed from the bath, the metal 0 deposited on the ornamentation, and usually a portion of the metal forming the ornamentation is removed by mechanical means, preferably by grinding. Fig. 5 illustrates the finished plate, in which the face b of the plate and the faces of the ornaments a a form an even surface. The parts forming the ornamentation are by this process more firmly secured than they can be when they are secured in grooves, cuts,

Articles formed 11 p may be by my improved process ornamented by securing the ornaplicable for the ornamentation of inferior metals.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The process for ornamenting metal goods,

the same consistingin securing the ornamental blanks to the surface of sheets or plates of metal, depositing a layer of metal over the surface of the sheet and the ornamental blanks, and removing the metal deposited on the ornamental blanks; as described.

2. The process for ornamenting metal goods, the same consisting in securing the ornamental blank to the surface of the part of the article to be ornamented, depositing a layer of metal over the surface adjacent to the ornamental blank and over the blank, and then removing the metal deposited over the surface of the ornamental blank, as described.

In testimony whereof I have signed m y name to this specification in the presence of two subscribing witnesses.

WM. A. DAY.
