METHOD- OF OIRNAMENTING METAL PLATEIS FOR JEWELRY.

' SPECIFICATION forming part of'Letters Patent No. 30 2,036, dated July 15, 1884.

Application filed May 14, 1884. (No model.)

Be it known that I,-'JAMEs RoTHsoHILD, a citizen of the United States, residing at Newark, in the county of Essex and Stateof New Jersey, have invented a new and useful Improvement in Metal Ornamentation, of which the following is a specification,

My invention relates to a method and means for ornamenting metal plates for jewelry-stock and for the finished production as a new arti'cle of manufacture.

" dented in simulation of engraved lines, said lines of each sectional division extending upwardfrom the base. By this means I produce an ornamental metal plate having a series of embossed figures, the polygonal sides of which present divers and diverse angles, which reflect and refract light at various incidences, the effect being to give to said metal and to articles of jewelry made therefrom the appearance of a series of gem-settings prismatic in character. This effect is heightened and in creased when the plate surface is multicolored. According to the present fashion, there is a great demand in the manufacture of jewelry for stock plate that has a party-colored or embossed surface, or both combined. The party-coloring is produced by a variety of treatments, not herein necessary to describe, as my invention can be applied to any description of multicolored plate the surface of which is normally smooth and unbroken, or to a plate with'a single surface color. Therefore -I will observe that I do. not in practice confine myself to plates either of a single-color or of party T color surface, the main object and purpose of my invention and the gist thereof being to upraise certain sectionally-divided portions of metal plates and to ornament in simulation of engraved lines the sides of each raised section, as and for the purpose herein described, and specifically pointed out in the claims.

Referring to the accompanying drawings, in which similar letters of reference indicate like parts on each figure, Figure l'represents a metal plate ornamented according to my invention. Figs. 2'and 3 are like views showin'g parts of the plate left plain. Fig. 4 represents the bezel of a locket or brooch embody.-

ing my invention.

A is a metal plate; a, the plain surface thereof; a, raised sectional divisions thereof, a lines on the raised sides of the divisional sections. When the figure is a cone or of any shape in which the base does not present a11- gular sides, it will be necessary to arbitrarily divide the line of-the base into sections, on each of which linesparallel-andextendingup ward from the base-line are to be placed, the parallel lines in each section to be in a different direction from those in the adjoining secsive elevations must have its sides indented or impressed in imitation of engraved lines. I This form is plainly illustrated on Fig. 3at B. It is not necessarythat the whole plane of the metal plate shall be covered with the desired ornamentation. Parts thereof may be left smooth and plain, as illustrated in Figs. 2 and 3. This plain surface may be further ornamented in a variety of ways-as, for instance, etching, chasing, engraving-and will provide a space for placing initials, mottoes, monograms, or the like thereonas, for instance, if the bezel C, Fig. 4, were stamped or embossed up and the central portion, 0', to consist of a'plain plate. So, too, may such plain surface be enameled or colored, in whole or in part, as taste or convenience may dictate. It will thus be seen. that Iprovide for an indefinite variety of ornamentation by my improvement and by combination with other well-known devices.

The process by means of which I produce the ornamented plates, as hereinbefore demale dies, the main pattern to be produced being in projectioi1 on the male die-roller,

the female die-roller being provided with cor responding depressions; but in addition thereto, upon the sides of each depression upon the female die, are a series of indented lines extending from the base of each side, and as the metal passes between the rollers the divisional sections are not only forced up or embossed by means of the male die, but the opposite side surface of each projection is imprinted by the said lineal indentations in exact imitation of line engraving. Of course, instead of using die-faced rollers, the sectional divisions, orna mcnted as described, maybe formed on the metal by striking it up between male and fe male hubs or dies.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The within-described method of producing ornamental metal work of the character specified,which consists of the following steps: first, preparing a male die with divisional sectional projections. the central point of each of said projections being higher than any other portion thereof, then preparing a female die with depressions coincident with the projections of the male die, then engraving 01' otherwise indenting upon the sides of each depression of the female die lines extending upward from the base of such depression, then placing a metal plate between the male and female die, and then subjecting said plate to pressure, as and for the purpose intended, substantially as described. 4

2. As a new article of manufacture, an ornamental plate for jewel ry-stock, having upon its surface a series of divisional sectional projections, each of which projections being higl1- est at its central point, in combination with lineal indentations upon the sides of each projection extending from the base upward, as and for the purpose intended, substantially as described.

3. As a new article of manufacture, an article of jewelry having an ornamental surface composed of a series of divisional sections,the center of each of said sections being the more elevated point thereof, the deflecting side of each of said sectional elevations being supplied with lineal impressions extending from the base upward, substantially as described.

4. As a new article of manufacture, a plate for ewelry-stock, having portions of the surface thereof smooth and plain and other por tions provided with sectional divisional projections,thc center of each of said projections being higher than any other portion thereof, the deflecting sides of each projection being supplied with lineal impressions extending from the base upward, substantially as described.

5. The combination, with the pariy-colored surface of a metal plate for jcwelcrs stock, of divisional sectional elevations having their highest point at their centers, and their dcflected sides provided with impressions extending in right lines upward from their bases, substantially as described.
