SETTlNG.

SEECIFICATION forming part of Letters Patent No. 729,606, dated June 2, 1903. Application filed November 12,1902. .Serial No. 130,939. (No model.)

To all whom, it may concern:

Be it known that I, FREDERICK L. KING, a citizen of the United States, residing Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Settings,of which the following is a specification.

My invention relates to gem-settings, and

nal blank from which my setting is formed Fig. 2, a plan view of the same after it has been (lapped, struck, and trimmed; Fig. 3, a

' section of the same on line at x of Fig. 2; Fig.

4, a plan elevation of the same after the swaging operation; Fig. 5, a section of the completed setting on line y y of Fig. 4; Fig. 6, a transverse central section of the completed setting engaging a pear], and Fig. 7 a side elevation of the same.

Like reference-letters indicate like parts throughout the views.

My setting is constructed as follows: From a thin sheet of metal an oblong rectangular blank A is out with projections a radiating from the four corners thereof, while two shorter projections 17 extend from the center of the longer margins of the blank diametrically opposite each other. (See Fig. 1.) This blank is next (lapped, struck, and trimmed into the form shown in Figs. 2 and 3that is, the blank A, including its radial projections a b, are bounded by an upturned marginal flange o. By swaging the portions of the marginal flange which bounds the sides of the blank they are folded inwardly and downwardly upon the blank A, orwhat is now the base or backing of. the setting, and .the short prongs bare forced upwardly from the folded portion or facing of the setting in a direction at right angles to the backing, and abutting against each other form a practically single short prong above the center of the base. By thesame swaging operation the prongs a are upset and their margins folded .together, so that the resulting setting has the appearance of Figs. 4 and 51 The ornament for which my setting is particularly Well adapted is an imitation pearlf.

.of the pearl is embraced by the setting-prongs a. It is evident that the ornament thus mounted is secure against rotatory or other displacement. While the filling fis not in all cases imperative, it is sometimes required when the orifice e happens to be too ample to snugly receive the prong e, in which case the prong extremity being buried in the wax the pearl is doublyinsured against any movement. j

Having thus described my invention, what I claim is- 1. A setting formed from a single metallic blank comprising a backing, a facing consisting of the inturned margin of the blank, a prong projecting from the edge of the inturned margin, and radial prongs upon the backing.

2. In a setting,the combination with the ornament provided with an orifice of a retaining member formed from a single metallic blank comprising a backing, a facing consisting of the inturned margin of the blank, radial prongs upon the backing and embracing the ornament and a prong projecting from the edge of the inturned margin extending into the orifice of the ornament.

3. In a setting, the combination with a hollow ornament provided with an orifice of wax within the ornament and a retaining member formed from a single metallic blank comprising a backin g, a facing consisting of the inturned margin of the blank, radial prongs upon the backing and embracing the ornament, and a prong projecting from the edge of the inturned margin extending through the orifice and into the Wax.

4. In a setting, the combination with a In testimony whereof Ihave affixed my sigsubstantially spherical ornament of a base, nature in presence of two witnesses.

prongs projecting from the margin of the base i for retaining the ornament in contact with FREDERICK KING 5 the base, and means above the center of the WVitnesses:

base independent of the embracing prongs AGNES I. BLAINE,

adapted to prevent rotation of the ornament. HORATIO E. BELLoWs.
