METHOD OF MAKING FINGER-RINGS.

Specification of Letters Patent.

Patented Feb. I, 1916.

Application filed August 4, 1914. Serial No. 855,041.

To all whom it may concern:

Be it known that, I, ALBERT F. VAUGHAN,

a citizen of the United States, residing at,

metal, while the covering is of a costlier metal, such as gold, so that the cup or setting in which the gem is secured will have its interior entirely covered with the white metal so as to thereby enhance the beauty of the gem, imitation, or otherwise, borne by the setting.

A further object of the invention is to economize in the cost of production of finger rings by simplifying the method of making same.

In the drawings: Figure 1, is a plan view of the blank from which the ring is formed; Fig. 2, is a plan View of the blank after same has been subject to the first step of the method; Fig. 3, is a similar view upon completion of the second step of the method; Figs. 4 and 5, are similar views of the third and fourth stages of the method; and Fig. 6, is a side elevation of the completed ring.

Fig. 7 is an end view of the blank; Fig. 8, is

a sectional view of the die used to initially act on the blank; Fig. 9, is a similar view of one of the dies which next acts on the blank; Fig. 10, is a similar view of the die which finally acts on the blank.

In proceeding in accordance with the present invention a section of clad metal is used which consists of a core 1, formed of white metal in imitation of platinum, and a covering 2 which. may be of gold or other desired metal.

The blank originally appears as shown in Fig. 1, and is then rolled or swaged by the dies of Fig. 8 or otherwise acted upon so as to appear in the form shown in Fig. 2, in which same has a central enlargement or bunched portion 3 annularly grooved at 4: by reason of forcing back of the metal. The blank is then further rolled or swaged by the dies of Fig. 9 to be brought into the form depicted in Fig. 3, in which its ends are reduced in diameter and consequently considerably lengthened. As the blank is operated upon by the different dies, by first placing one and then the other end of the blank in the dies, the tendency is to form or bunch the metal outwardly or toward the blank center. As the dies are of gradually increasing length, the metal being forced toward the center will rise in the nature of a fin giving the appearance of a groove in the center. The next step in the method is to swage the enlargement 3 into the form shown in Fig. 4: by the dies of Fig. 10, in which the fingers or prongs 5 of the setting are formed in part, about a central pillar 6. The next step in the method is to bur or drill out the pillar 6, thus leaving the fingers 5 in their completed form as shown in Fig. 5, of the drawings. The burring or drilling of the pillar leaves the fingers or prongs 5 complete, and the walls 7 in the body of the ring, which walls are formed by the burring or drilling, with a white face due to the fact that the drilling has been through the white metal, which latter was bunched during the swaging or rolling operation shown in Figs. 2 and 3. The final step in the method consists in finishing the fingers or prongs 5, that is in shaping them to hold the gem and in oining the ends of the blank to form the completed ring as depicted in Fig. 6 of the drawings.

What is claimed is 1. The herein described method of making finger rings which consists in covering a core of white metal with a finishing metal, then in forming the blank with a central enlargement by rolling. or swaging same so as to bunch the white metal in said enlargement, then in forming the fingers of the setting in part about a central pillar, burring or drilling the pillar out to complete the formation of fingers and to simultaneously expose the white metal so that the latter provides a coating for the interior of the setting, and finally in securing the ends of the blank together to form the completed 2 The hereindescribed method of making finger rings which consists in bunching the white metal of a blank having a white metal core to form a central enlargement, then in swaging the blank to form same with partially formed fingers for the setting, and

then in drilling out the center of the enlargement so as to expose the White metal and in assembling or connecting the ends of the blank.

3. The hereindescribed method of making finger rings Which consists in bunching the White metal of a blank having a White metal core at approximately the center of the blank, then in forming said bunched part with partially formed fingers for the setting, and then in removing the material from the center of the bunched part to expose the White metal and finally in connecting the ends of the blank.

In testimony whereof I have signed my 15 name to this specification in the presence of tWo subscribing Witneses.

ALBERT F. VAUGHAN.
