Application filed September 12, 1925. Serial No. 56,097.' I A This invention relates generally to the manufacture of gems known as cabochons and more particularly to the application thereof for various purposes.

The subject matter of this invention is closely related to the invention described in my co-pending application Ser. No. 56,098, filed Sept. 12, 1925.

\ For a full understanding of the invention and characteristic features thereof, reference is made to the accompanying drawings in which- Fig. 1 is a plan view of a plate carrying a plurality of cabochons arranged singly and in p Fig. 2 is an elevation of a part thereof, partly in section;

Figs. 3 and 4 are side elevation and. end view, respectively, of a ortion of the plate carrying a group ofca ochons, as severed from the plate and mounted on a pin;

Fig. 5 is a plan view of another portion of a plate carrying another group of cabochons, severed from the plate; and

Fig. 6 is a plan view of a modification of the form. shown in Fig. 5.

This invention is based on the discovery more fully described in my said co-pendmg application, that when a body, as for instance a plate, having a perforation is pressed upon a body of molten vitreous material, the upper surface of the material assumes a definite curvature. Thus when the perforation is circular, the upper surface 1S spherical. The curved cabochon surface is so uniforml smooth that even the best and most care ul polish couldnot improve it.

Since a natural polish is thus obtained as the result of the process of producin the cabochons, the latter may be forme and mounted by one and the same 0 ration. Advantage may be taken of this unique feature in many ways and for numerous purposes. K

I therefore wish to emphasize that the drawings are intended merely as generally illustrative and suggestive of the almost unlimited scope of application of the invention.

In Figs. 1 and 2 I have shown a plate 1 of relatively-small thickness and generallyof the order of stock used for mounting gems and precious stones. This plate, which may be called a stencil plate is shown as perforated and carryin 4 groups a, b, 0, and d of cabochon gems. roup a represents a plurality of typical cabochons 10. Group b represents a plurality of oval cabochons 11. Group 0 indicates a group composed of a plurality of different sized cabochons 12,

13 and 14 representing an ornamental unit. Gp-oup d indicates a relatively large number 0 cabochons 15 defining the letter A.

The common characteristic feature is a slight bevel or flaring 2 of the perforations at the lower side of the plate and preferably also a similar flaring 3 at the'upper end of the perforations; When molten glass, or V i vitreous material in general, is pressed through the perforations as for instance by pressing the plate 1 upon a. body of molten glass, the glass as it issues from-the, perforationsexpands slightly and thus after coolmg cannot be removed in a downward direction. At the same time the molten glass fills the flaring portion 2 so that after coolmg a secure anchor is also provided against motion in the other directon. After the cabochons have been formed, the excess glass at the bottom is removed as by grinding and then the single gems, groups or units are cut from the plate with enough of the metal to provide a mounting.

Thus, as indicated group 0 is shown as cut out from the plate 111 the form, of a disk 4 and then mounted upon a pin 5 forming a stick in. As indicated in Fig 5, group (i may e cut out to serve as an ornamental symbol.

As indicated in Fig.6, the letter A may be formed by long cabochons instead of a group of circular forms. The elongated perforations-6act the same as other erforations. The cabochons produced there y are uniforml rounded and form in substance semicylinders with the exception that the ends are also rounded. v

The form of the gem depends generally on the outline of the perforation. The curvature of the upper surface adapts itself to the different conditions.

In the foregoing I have restricted myself to the illustration of groups formed by a'single any desired plan and profile. When per-- forations are so close to each other that the molten material issuing at the top coalesces or flows together, a single surface is produced exhibiting to a greater or lesser degree the characteristics of the individual forms as they would be produced separately from each other, but these forms are modified more or less by the degree of coalescence permitted. One illustration of this is the form shown in Fig. 6. The elongated perforations are in effect a large number of circular perforations in juxtaposition and so overlapping each other as to form two straight side Walls. If the overlapping were such as to produce scalloped side walls, the cabochon produced would include a plurality of mainly spherical bodies interconnected by webs the Width and heights of which is a function of the degree of overlap. There is, in fact, no limit in respect to the formation of modified cabochon bodies. There is not a geometrical configuration that may not be simulated. Flowers and animals may be imitated more or less ornamentally depending on the skill and experience of the designing artist. It would be futile within the scope of this specification to even attempt to give illustrations of the various forms that may be created by the method described.

It is needless to say that the plate need not be plane or that the flaring of the openings need not be produced by beveling or counterboring. The perforations may be produced by punching dies or in fact in any well known manner. The recesses for producing the anchoring effect may be rovided by bending, indenting, pressing t e plate or stock upon which the mounting is to take place.

Aside from the general utility of the invention in respect to the production of gems and ornamental designs proper, as above referred to, there is another field of application which I consider of great importance. The invention is particularly applicable to the formation of signs of all descriptions. Thus any name word or phrase may be composed of caboc ions, as suggested in Fig. 5. The cabochons may be of any color or of different colors. In the day time, the signs are visible by light reflections,.while provisions may be made to make them conspicuously visible, at night by transmission of light through them. The art of illumination is widely understood and appreciated and has proceeded to such degrees of specialized skill bordering almost on the realm of magic, that it would be superfluous to particularly indicate some of the many devious ways by which the artistic effect of signs made in accordance with my invention may be conspicuously brought out.

Also inthis respect there is no limit to the combinations of words, signs, symbols and emblems that may be produced as the result of creative imagination.

I claim:

1. An ornamental structure of the character described, comprising a plate having substantially plane surfaces and an opening extending from one plane surface to the other, and a body of vitreous material in said opening, having portions preventing removal of the body in either direction, one end portion presenting a symmetrically rounded surface having the characteristics of a highly polished cabochon surface.

. 2. An ornamental structure of the character described, comprising a plate having substantially plane surfaces and an opening extending from one plane surface to the other, the opening having a lateral enlargement of smaller axial extent than the thickness of the plate, and a body of vitreous material in said opening having a laterally enlarged portion corresponding to and filling the enlarged part of the opening, one end portion'of the said body presenting a symmetrically rounded surface having the characteristics of a highly polished cabochon surface.

3. An ornamental structure of the charac ter described, comprising a plate having substantially plane surfaces and an opening extending from one plane surface to the other, the opening having an enlargement adjacent to one surface, and a body of vitreous material in said opening, having at one end an enlargement corresponding to and filling the EDWARD J.
