JAMES A. DORAN, 0F PROVIDENCE, RHODE ISLAND.

ART OF MAKING CLUSTER-SETTINGS.

Specification of Letters Patent.

Application filed February 19, 1910.

Patented July 19, 1910. Serial No. 544,843.

To all whom it may concern:

Be it known that I, JAMEs A. DORAN, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented a certain new and useful Improvement in the Art of Making Cluster-Settings, of which the following is a full, clear, and exact description.

The object of this invention is to produce economically a cluster setting for jewels, such as stones, gems, or other ornaments, which may be given a variety of shapes, and will retain the jewels firmly in place, with out the use of solder for connecting the several settings constituting the cluster.

The invention consists in the improvement in the art of forming jewel settings from sheet metal by a series of cupping or drawing and cutting operations, whereby a series of closely connected individual settings, cups, hearings or seats, with integral prongs, is produced, capable, as a whole, of being given a variety of shapes, to produce pinheads, hat-ornaments, and a great variety of articles, both utilitarian and ornamental, all as I will proceed now more particularly to set forth and finally claim.

In the accompanying drawings, illustrating the invention, in the several figures of which like parts are similarly designated, Figure l is a plan view of part of a cupped sheet of metal, and Fig. 2 is a par tial section and edge view thereof. Fig. 3 is a top plan view of a similar sheet having the cupped portions provided with cross cuts, to form the claws or prongs for retaining the jewels, and Fig. 4 is a partial section and edge view thereof. Fig. 5 is a top plan view of the sheet of Figs. 3 and 4 after being drawn to produce the cups, bearings, or sets for the jewels, and the claws or pron 's, and Fig. 6 is a partial cross-section and edge view thereof. Fig. 7 is a bottom plan view, and Fig. 8 is a top plan view, on a larger scale, of a single setting complete and parts of eight adjacent settings, all connected in accordance with this invention. Fig. 9 is a view similar to Fig. 6 but showing settings having solid instead of perforated bottoms. Fig. 10 is an elevation of a cluster setting for a hat pin.

A sheet, 1, of suitable metal stock is drawn to provide a series of cone-like projections 2, and these are provided with the crosscuts 3 which divide each projection into four equal sections 4. At uniform intervals between these cross-cuts projections, the sheet of metal is provided with holes 5, and with these holes as centers, the metal is drawn in a direction opposite to the projections 2 and so as to form cups 6 of sub stantially circular cross-section and of the form of a truncatedcone, to receive the jewels, with the sections 4 standing up from their upper edges to form the claws or prongs for holding the jewels in place in the cups. Each cup so drawn is connected with its four adjacent similar cups by means of strips 7 integral with them and with the sheet from which all are produced, as more clearly shown in the enlarged views Figs. 7 and 8. In thus drawing these cups the holes 5 are necessarily stretched, but without detriment to the setting. As shown in Fig. 9, the cups may be drawn without forming the holes 5, and in such case the bottoms of the cups will be solid.

As an illustration of one use of my invention, I have shown a hat-pin having a flat, angular setting; but, as already stated, the setting may be variously shaped, and used for a variety of purposes.

By the invention, a cluster setting of any number of self-connected, individual jewel settings (cups, seats, or bearings), may be economically produced, and without the use of solder or other extraneously applied connections.

In accordance with former practice in making cluster settings, the work depended upon the correctness of the workmans eye and the steadiness of his hand to secure regular or uniform spacing, whereas by my invention absolute regularity and uniformity are secured, and the symmetry of the product assured. Furthermore, where individual settings are used, it often happens that some of them are not thoroughly soldered, and consequently soon fall oii' either in handling or in use.

Efforts have been made to produce cluster settings in one piece, but. the practice followed in such instances has resulted in such a wide spacing apart of the individual settings as to preclude obtaining the desired cluster effects.

In following the present invention, it is possible to make sheets of settings connected as described, and then cut up the sheets into such portions as may be necessary to form the desired cluster setting, and these cluster settings may be bent to form various shapes,

such as hemispherical, conical, cylindrical, saucer-shape, etc.

From the foregoing, it will be understood that the raw product of this invention is practically, jewelers stock, in which the cups 6 constitute bearings or seats for any suitable ornaments, such as stones, gems, or other articles 8, Fig. 10, all which I intend to embrace by the use of the term jewel.

It will be understood that in using the stock, the half settings shown at the ends in Figs. (3 and 9 would be cut off.

lVhat I claim is 1. The improvement in the art of making cluster settings from sheet metal, which consists in forming a series of contiguous upright projections in the metal with intervening solid portions, then separating the metal of the projections to form the prongs, and then cupping these solid portions in the reverse direction to the projections and developing the intervening connections of the several settings.

2. The improvement in the art of making cluster settings, which consists in drawing up conical projections in a sheet of metal, cross cutting said projections so as to leave solid connections between them, and then cupping the metal between the projections to form the jewel cups, and drawing up the proximate cross-cut sections of four adjacent projections to form the prongs, said solid connections tying the individual jewel cups in series.

3. The improvement in the art of making cluster settings, which consists in drawing up conical projections in a sheet of metal, cross cutting said projections so as to leave solid connections between adjacent surrounding projections, and then cupping the metal between the projections to form the jewel cups, and drawing up the proximate crosscut sections of four adjacent projections to form the prongs.

4. The improvement in the art of making cluster settings, which consists in drawing up conical projections in a sheet of metal, cross cutting said projections so as to leave solid connections between the adjacent surrounding projections, perforating the sheet of metal at regular intervals between the conical projections, drawing frusto-conical cups in said sheet with said perforations as centers, and throwing up the metal between the cross cuts to form prongs on the edges of the cup portions.

In testimony whereof I have hereunto set my hand this 17th day of February A. D. 1910.

JAMES A. DURAN.

It is hereby certified that in Letters Patent No. 964,624, granted July 19, 1910, upon the application of James A. Doran, of Providence, Rhode Island, for an improvement in the Art of Making Cluster-Settings, errors appear in the printed specification requiring correction, as follows: Page 1, line 12, the Word sets should read seats, and same page, line 58, the compound word cross-cuts should read crosscut; and that the said Letters Patent should be read with these corrections therein that the same may conform to the record of the case in the Patent Olfice.

Signed and sealed this 2nd day of August, A. 1)., 1910.
