Specification of Letters Iatent.
Patented Aug. 30, 1921.-
Application filed. June 7, 1920. Serial No. 387,043.
To all whom it may concern Be it known that I, THOMAS CnirMINe, a citizen of the United States, reslding at Los Angeles, in the county of Los Angeles fullest extent. e
Other objects and advantages will appear hereinafter from the following specification.
Referring to the drawings, which are for illustrative purposes only,
Figure 1 is a side elevation of a mounting in the form of a ring illustrating a setting embodying a form of my invention.
Fig. 2 is a face or plan View of the mountin shown in Fig. 1.
-ig. 8 is an enlarged vertical sectional view on line3-3, Fig. 2; and,
Fig. 4: is a face or plan view of that portion of the mounting shown in Fig. 3.
The mounting is shown in the form of, a ring 5, the shanks 6 of which terminate in shoulders 7, the shoulder portions being connected at their outer ends forming a body portion provided with a conical recess 8 which recess is provided with an opening 9 in the bottom thereof; The mounting is preferably made of gold of which metal the body portion with the recess 8 therein is formed. The inner face of the recess 8 is covered with a series of plates 11 of platinum, forming a facing for the recess, such plates being soldered to the gold of which the body portion is formed. The plates 11 are so shaped and placed within the recess as to form radially disposed slots between the adj acent'plates into each of which is inserted an outwardly extending prong 12 formed of a fiat bar of platinum, such bars being soldered to the face of the recess and to the platinum plates, This construction forms a neat setting of durable form as a rigid connection between the prongs 12 and the body portion of the mounting is obtained. Each prong 12 is provided with an upper edge substantially parallel to the lower edge of the prong to receive, the diamond indicated in'dotted lines at 14 in Figs. 3 and 4, to form gripping poin'ts 13, such diamond being held thereon by upsetting the upper end of the prongs over the edge of the diamond. 7
It is particularly to be noted that each angularly disposed lower edge of the diamond indicated at 15 is substantially parallel to the plane of a plate 11 of platinum and that the faces of the prongs and the exposed plates 11 exposed to the diamond are all of platinum. These surfaces, that is, the surfaces of the prongs and the plates 11, are polished to a high degree of brilliancy so that the rays of light striking such surfaces are deflected into the diamond thereby enhancing the brilliancy of the stone by overcoming the diffusion of therays of light which ordinarily takes place in the common form's of settings. 1
The setting formed as shown and described provides a setting in which all surfaces of the setting presented to the diamond consist of polished platinum and by leaving a space between the diamond and the platinum faces, the stone and polished faces of the platinum maybe easily cleaned so that any accumulation of dirt and conse quent dullness of the stone resulting-therefrom is avoided. The cleaning action is also facilitated by the opening 9 in the bottom of the recess 8.
What I claim is 1. A jewelry setting comprising a member having a conical recess formed therein, a series of plates of platinum secured to the face of said recess, spaced apart from each other to form slots therebetween, a platinum prong in each slot having a lower edge resting on the face of said recess and having an upper edge substantially parallel to the lower face arranged to support the gem and a gripping point on each prong arranged to engage the gem.
PA ENT? oinei'ceaf 2. A jewelry setting comprising a ring i member having a conical recess formed therein terminating in an opening extending through the ring member, a facing of polished metal forming the face of said recess, prongs of polished metal extending upwardly from said facing each having an upper edge substantially parallel to said facing to support the gem, and a gripping point on each prong arranged to engage the gem.
In testimony whereof, I have hereunto set my hand at LosrAngeles, California, this 28th day of May, 1920.
t THOMAS CUMMING.
