Leners Patent No. 86,864, wat Femm 9, 1869.

ORNAMENT ron JEWELRY, sc.

'lha Schedule referred to in these Letters Patent and making part of the name.

To all whom 'it lIna/y concern Be it known that I, GELrUs E. Rrcnnnns, of North Attleborougb,'in the county of Bristol, and State of Massachusetts, have invented a new Manufacture of Glass Ornament for Setting in Jewelry, &c.; and I do hereby declare that the following is a full, clear, and

exact description ofthe same, reference being had to the accompanying drawings, making part of this speciiication, in which- Figure 1 is a plan and section ci the said glass ornament.

Figure 2 is a plan and section of said ornament,

moulded in form, but uncut. Figure 3 is a plan, and

Figure 4 is an edge View of a piece of s'tratafglassf1 so called, from which said ornament is produced.

Similar letters indicate like parts in all the iign'res. My invention consists of a new ornamentfor setting in jewelry, produced from glass in different-colored strata, by displacing the strata from their original position in the formation of the piece, by pinching or moulding, and afterwards removing a certain portion of one or more of the strata, to give it thereqnisite form and ornamental effect, by grinding and polishing, in the usual way of cutting such ornaments of precious stones.

The strata-glass from which the said ornament is produced is composed of two or more contrasting-colored strata, lying parallel to each other, and for convenience of handling may7 bein the form cfa strip like that represented in figs. 3 and 4. This strip is rendered plastic by heat, and while in this condition a piece is cut therefrom, in the required form, by means of a pair of dies, in the two opposite jaws of a pair of pincers, which dies, besides cutting out the piece, also produce thereon a design, emblem, or initial, in relief, from a like figure cut into the ground-face of oneof the dies, and which has the effect, by the'pinching-operation, todisplace the strata, as shown in fig. 2,v the upper, light stratabeing depressed, at e e', and the lower,

darker lstrata being elevated, as at a a, above the plane ofthe former, c e. The back of the piece is also slightly depressed or concaved, to throw or compress the material of the dark strata well into the sharp and minute features of the die, thus producing the moulded piece shown in iig.` 2. The prominent portions of the upper strata, constituting the design and border, are then cut away, by grinding ofi' the face and periphery of the piece in the plane of the dotted lines al, g g, iig. 2, which exposes the darker strata in the design and border on the light ground of the depressed upper strata e e, and produces a highly-ornamental effect, similar to that of designs cut in (strata) precious stones, as, for instance, the sardonyx and cameo-shell, with the advantage that the glass ornamentis quite as durable, and comparatively inexpensive.

What I claim, and desire to secure by Letters Patent, is

The ornament forjewehy, moulded and cut fromY strata-glass, substantially as herein described', as a new article of manufacture.
