SETTING FOR PRECIOUS STONES.

Specification of Letters Patent.

Patented Feb. 17, 1920.

Application filed April 3, 1919. Serial No. 287,168.

To all whom it may concern:

Be it known that I, JosErH 0. WHITE- HOUSE, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Settings for Precious Stones, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to an improved setting for precious stones and has for its particular object to provide means for setting a number of small precious stones in a group so that the setting as a whole will have the effect in appearance of a single large gem.

The present invention is an improvement of the general construction shown in my Patents Nos. 1,204,915, 1,204,916 and 1,204,917, issued Nov. 14th, 1916.

An object of the present invention is to provide a settingof the character contemplated which will require no solder to secure the several parts together as is the practice in settings of this character. By eliminating soldered joints the settings are made simpler and are also improved in appearance.

In the accompanying drawings;

Figure 1 is a side elevation of a ring provided with the usual setting for mounting a single gem and having a group setting of the character contemplated in my invention applied therein;

Fig. 2 is a plan view ofthe ring shown in Fig. 1;

Fig. 3 is a plan view of the setting disk for mounting the group of small stones;

Fig. 4 is a side elevation of the setting disk; and

Fig. 5 is a detail view of the separate reflector frame which constitutes the lower portion of the setting.

As here shown the invention as applied in a ring consists of the usual ring portion 1 provided with a suitable setting 2. A group of small gems 3 is mounted in a disk 4 provided with suitable apertures 5, the apertures being arranged, preferably in the manner shown consisting of a central aperture and a series of six apertures arranged around the outer edge of the disk to complete the group. Within the setting 2 is the separate reflector frame which, as here shown, consists of a concave base portion 6 and upwardly extending projections 7 which are spaced apart as at 8 and are preferably provided with apertures 9 conforming in outline substantially to the shape of the projections.

- The frame portions of the projections consist of inclined side members 10 and 11 secured at their lower ends to the base 6,

- inclined outwardly from the base and oppositelv from each other and terminating in end members 12 and 13 which incline inwardly from the members 10 and 11- and form a juncture, as at 14, constituting the apex of the projection.

The purpose of the cluster frame and the novel manner of combining the same with the ring setting is to give the group setting the effect of a single large stone setting. To this end the cluster frame is made of light reflecting metal, preferably of the finer qualities of composition metal, the projections 7 having the effect in appearance of the facets of the pavilion portion of a large diamond or other precious stone.

The advantages of making the reflector frame detached from both the mounting disk 4 and ring setting 2 consist in the elimination of the soldering operation which, in view of the character of the metal used in settings of this character effects a material saving in cost, and the improved appearance of the setting as a whole, all the lines of the reflector frame being preserved in perfect, outline and therefore improving the desired effect of having the appearance of the facets of a precious stone.

A further advantage of-the' present improved setting consists in the greater facility with which the settings may be changed. It is quite common with the owners of rings or pins having settings of this character to have the settings interchangeable, that is, changing the setting from a ring to a pin and vice versa, or substituting or interchanging different groups of gems in the same mountings.

It will be observed that the inclined projections of the reflector frame, as here shown, are disposed between the prongs or clamps of the ring setting 2 so that the apex 14 thereof comes substantially central in the space between the prongs; also that the apexes of the projections contact with the lower surface of the disk 4 so that the apparent outline of facets is properly accomplished.

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

1. In a setting of the character described, the combination of a series of setting prongs spaced apart and a space centrally defined thereby, a cluster plate for small stones supported by said prongs above said space, and a detached reflector frame confined in said space and having a base portion and outlined projections terminating in apcxes contacting with. the cluster plate and defining in effect the facets of the pavilion portion of a single stone.

2. In a setting of the character described, the combination of a series of setting prongs spaced apart and a space centrally defined thereby, a cluster plate for small stones. supported by said prongs above said space, a detached reflector frame confined in said space and having a base portion and outlined projections terminating in apexes between said prongs and defining in effect the facets of the pavilion portion of a single stone.

3. In a setting of the character described, the combination of a series of setting prongs spaced apart and a space centrally outlined thereby, a cluster plate for small stones sup ported by said prongs above said space, and a detached reflector frame confined in said space and having a concaved base portion and outlined projections extending there from and terminating in apexes adjacent said prongs and defining in effect the facets of the pavilion portion of a single stone.

4. In a setting of the character described, the combination of a series of setting prongs spaced apart and a space centrally outlined thereby, a cluster plate for small stones sup ported by said prongs above said space, and a detached reflector frame confined in said space and having apertured projections contacting with the cluster plate and defining in effect the facets of the pavilion portion of a single stone.

5. In a setting of the character described,

the combination of a series of setting prongs spaced apart and a space centrally outlined thereby, a cluster plate for small stones supported by said prongs above said space, and a detached reflector frame confined in said space and having a base portion, oppositely inclined projections extending upwardly from said base, and portions inclined inwardly from said projections converging in apexes between said prongs and defining in effect the facets of the pavilion portion of a single stone.

6. In a setting of the character described, the combination of a series of setting prongs spaced apart and a space centrally defined thereby, a group of gems mounted in a cluster plate supported by saidprongs above said plate, a detached reflector frame confined in said space and consisting of concaved upwardly inclined projections apertured to define in effect the facet outlines of the lower portion of a single stone.

7 In a setting of the character described, the combination of a series of setting prongs spaced apart and a space centrally defined thereby, a group of ems mounted in a cluster plate supported by said prongs above said plate, and a detached reflector frame confined in said space by said prongs and plate and consisting of concaved upwardly inclined projections apertured to define in eflect the facet outlines of the lower portion of a' single stone. 7

8. In a setting of the character described, the combination of a series of settingprongs spaced apart and a space centrally defined thereby, a group of gems mounted in a cluster plate supported by said prongs above said plate, a detached reflector frame confined in said space and consisting of upwardly extending projections, defining in effect the facet outlines of the lower portion of a single stone. 7 r

9. In a setting of the character described, the combination of a series of setting prongs, and a reflector frame fashioned to represent the facets of the'pavilion of a single stone, and removably fitted and held within the space defined by said prongs.

In testimony whereof, I affix my signature.
