GEM-SETTING.

SPECIFICATION forming part of Letters PatentNo. 270,921, dated January 23, 1883.

Application filed October 28. 1882.y (No model.)

To all whom it may concern Be it known .that I. DEWEY F. ADAMS, of the city and county of Providence, and State of Rhode Island, have invented a new and useful Improvement in Stone-Set Plated Jewelry, of which the following is a specification.

Myinvention relates to a gein-settin g for jewelry-such as an ear-ring or button-the face member ot' which consists ot' a setting composed of metal known as stock-plate,7 in the form of a base or back having an upwardlylprojecting integral wall or ange, and of a stone having a beveled edge or side inserted into said setting from the face side thereof and secured therein. In articles of jewelry thus formed it has been common to secure the stone in its setting by cement, by burnishing or slightly bendinginward the upperedge of the wall or ange of the setting, or by knurling or indenting said edge toV produce slight inward projections which shall engage the'bevele'd side or edge of the stone and hold the same in place. By all these methods of securing the stone in its setting the brass or other base metal composing the greater portion of the 'H plated stock7 of which the setting is made comes to view on the upperedge of said tiange or wall and soon becomes oxidized, thereby presenting an unsightly appearance.

lily improvement consists in securing the stone in its setting by soldering to the upper edge of the wall or liange of the setting an anunlus or rim, of gold or other superior metal, in such a manner as to cover from view the that said annulus or rim shall project inwardly Y from the ange and engage the beveled edge dr side of the stone and secure it in position.

Referring to the drawings, Figure l represents in perspective an ear-ring embodying my improvement. Fig. 2 shows a section of the same on an enlarged scale.

A is the setting,7 which is composed of stock-plate formed of base metal a, and.supe rior metal b. This setting is in the form of a cup having a bottom plate, A, and an integral wall or ange, A2.

C is the stone, having a beveled edge or side.

D is the annulusor rim, of gold or other superior metal, which may be very thin. After the stone C has been inserted'into the setting A .from the face side thereof, the annulus or rim D is secured by soft solder to the edge of the dange A2, so as to cover the base metal a of said flange, and so as to 'project inwardly therefrom and engage the stone, as shown in Fig. 2. By this construction only superior metal comes to view or wear on any part ofthe face member of the article, and an appearance closely resembling an article made ot' solid superior metal is obtained. The face ot' the annulus or rim D may be ornamented in any preferred manner, and effects be thereby secured which could not be obtained by thecommon constructions, where the edge ofthe fiange A2 is simply bent inward or knurled.

What 1 claim, and desire to secure by Letters Patent, is-

As a new article of manufacture, a gem-setting forj'ewelry, consisting of a cup-shape setting of plated stock, composed of a back-plate, A', and a wall or ange, A2, a stone having a beveled edge inserted into the setting from the face side thereof, and anannulus or rim, D, ot' superior metal, which covers the edge of the flange A2, and is secured thereto, after the stone has been inserted, for the purpose of holding the stone in place,substantially as set forth.

DEWEY F. ADAMS.
