United States Patent FINGER RING WITH SETTING MOUNTED ON SLOTS IN RING SHANK Raymond G. Lutrario, Providence, R. I., assig nor to Uncas Manufacturing Company, av corporation of Rhode Island Application December 8, 1954, Serial No. 473,860 4 Claims. (Cl. 6315.7)

This invention relates to a finger ring and more particularly to a gem mounting and the method of making the same.

Finger rings are usually constructed with a top member which is secured to the shank or band which extends about the finger and frequently auxiliary ornaments are located each side of the top member to enhance the appearance of the ring. A ring of this construction is usually formed by hard soldering the shank to the top member and then soft soldering individually the auxiliary side ornaments to the shank or to the top member or to both at either side of the top member. This requires three distinct soldering operations and considerable skill in holding the parts in aligned relation so that they will be symmetrically located.

One of the objects of this invention is to simplify the assembly of the diiferent parts of the ring.

Another object of the invention is to assemble the different parts of the ring without the use of solder.

Another object of the invention is to provide a construction in which the setting of the stone in the ring will bind the assembled parts together without the use of solder.

A still further object of the invention is to provide a novel gem mounting which may be assembled to a base without the use of solder.

With these and other objects in view, the invention consists of certain novel features of construction as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a top plan view of the finger ring;

Figure 2 is a partial sectional view taken through the stone setting;

Figure 3 is an exploded perspective view showing the different parts which go to make up the ring in somewhat the relationship which they bear to one another in the assembly.

In proceeding with this invention which is illustrated and described in connection with a finger ring, I bend into circular form the shank portion of a ring, notching it adjacent the ends. I then position the notched and end portions of the shank in a cup stone setting and place within the setting a locking member in the form of a yoke to fit into the notches in the shank which closely fit the notches and assist in locking the ends of the shank together. I then position the stone in the cup setting and force this against the locking part as the stone is set so as to secure the assembly together. By this arrangement the setting of the stone holds the parts assembled.

With reference to the drawings, the ring shank is designated and is bent up from a strip of wire which is of a length to give approximately the encircling size desired. The two end portions 11 and 12 are beveled as at 13 and 14 (see Figure 3) for a purpose which will hereinafter appear. The end portions are also notched as at 15 with right angular abutting surfaces 16 and 17. The cupshaped setting designated generally 18 is provided with 2,763,140 Patented Sept. 18, 1956 ice as at 22 and 23, while prongs 24 at the junction of the side and end portions 22 and 23 serve for setting a stone designated generally S, shown in perspective in Figure 3, in the cup setting. The side walls 20 and 22 are notched as at 25 for the reception of the shank 10 which may be set into these notches 25 and rest upon the bottom edge 'of these notches and adjacent to the bottom wall 19.

A locking member designed generally 26 is shown in perspective in Figure 3 as providing a yoke portion 27 with upwardly extending arms 28 which broadens outwardly as at 29 in a portion which will rest upon the upper edges 22 of the setting, while the outwardly extending portion of the arms 30 extends from these broadened portions 29 for an extent to contact the shank 10. The yoke 27 is so dimensioned that it will -fit into the notches 15, its inner edges 31 engaging the abutments 16 of the notches 15 so as to prevent spreading of the shank ends, while the outer edges 32 will be such as to closely fit the abutment surfaces 17 of the notches. The inclined arms 28 being in effect a planal continuation of the edges 32 will engage the edges of the abutment 17 and when pressure from setting of the stone is exerted upon these portions 28, the member 26 will be forced downwardly into recess 15, the outside of arm 28 sliding along the corners of the abutment 17, urging the ends of the ring apart to be limited by the abutting surfaces 31 and 16.

In assembly, the cup setting 18 is placed within the ring shank 10 and the ring shank ends are positioned in the notches 25 in this setting. The member 26 is then positioned with its yoke portion 27 within the setting and its frame-like yoke located in the notches 15, the arms 30 extending into contact with the shank 10 and the broadened portions 29 of the ornament engaging the edges 22 of the setting. The stone S is then placed so that its beveled under surface 33 will engage the arms 28 (see Figure 2) and this stone is then locked in position by the fingers 24 being bent over the corners of the stone. In bending these fingers over, the stone will be pressed into its setting and the purpose of the beveled ends 13 in the ends of the shank is to give clearance to the apex of the stone S, thus preventing it from engaging the shank and yet permitting it to be set low in the setting. The pressure of the stone will force the ornamental member 26 to bottom the notches 15, and in so doing, the inclined arm portions 28 may move the ends of the ring away from each other but in any event will lock the ends of the shank from moving outwardly away from each other by the abutting surfaces 16 and 31. The final result is substantially shown in Figure 2 in which the ends will be held in slightly spaced relation with the stone entering into the bevel 13 between these ends while through the stone the entire assembly is locked together. Frequently in this operation the shank may be distorted, and it will then be arbored to bring it to proper shape and proper size.

I claim:

1. A gem setting comprising a cup having a bottom wall and a plurality of sides extending therefrom with gripping fingers, opposed transverse openings through opposite sides, a shank positioned over said bottom wall and through said openings, said shank having spaced notches in its outer surface in the portion extending between said sides, a locking member having a yoke positioned in said notches with arms flaring from the yoke and extending in a direction away from said bottom wall, a stone engaging said member, said fingers on said cup engaging the outer face of the stone and forcing the lower surface of the stone against the locking member, thereby forcing the yoke into said notches to lock the parts together.

3 2. A finger ring comprising a shank with a notch in each end portion spaced from the terminal thereof, a cup setting having a bottom wall and a plurality of sides extending therefrom with gripping fingers, a transverse 3. A finger ring as in claim 2 wherein the ends of said shank are beveled to provide clearance for the stone.

4. A finger ring as in claim 2 wherein the flaring arms provide a wedge which serves to spread the end portions opening throughv opposed. id h d of id h k 5 of the ring as the stone is forced into setting position and positioned in said opening over said bottom wall and with said notches between said opposed sides, a locking member having a yoke positioned in said notches with arms flaring from the yoke and extending in a direction away from said bottom wall, a stone engaging said locking member, said fingers on said cu engaging the outer face of the stone and forcing the lower surface of the stone against the locking member, thereby forcing the yoke into said notches to lock the parts together.

the yoke enters said notches.
