New York, N Y.

Application February 5, 1937, Serial No. 124,175

3 Claims.

My invention relates to a finger ring in which the annulus is made from a blank, and the new feature is the formation of the side pieces for the crown of the ring from the blank of the annulus.

The invention is an improvement over my application, Serial No. 102,716, filed September 26, 1936.

An object of the invention is to provide a stamped ring in which the annulus shaped from a blank has, as an integral part thereof, side pieces raised from the body of the blank with side walls of the side pieces drawn from the blank.

Another object of the invention is to provide a stamped ring in which the annulus shaped from a blank has, as an integral part thereof, box sides extending from the sides of the blank with portions of the blank spanning said box sides.

In rings of this type madehithert'o, there is an annulus blank and a crown blank. The crown blank forms the top and the side pieces, whereas in my ring the side pieces and the box for the jewel top are formed from the blank for the annulus.

.By providing a ring adapted to receive a top without side pieces, Ipermit a jeweler to have a selection of tops for different sizes of jewels or stones to fit the same annulus. By formingthe side pieces from the blank of the annulus, with the lateral sides or walls of said side pieces drawn from the blank, I provide a rigid structure which requires a minimum amount of soldering to complete the ring. In the rings hitherto made, the side pieces as well as the top, had to be soldered to the annulus of the ring in the assembling, while in my ring where the top is used, only the top has. to be soldered.

Another advantage of my ring is that it permits a jeweler a selection of any desired top for the same annulus, without the necessity of using independent side pieces in conjunction with the top for a large sized jewel or stone. By drawing the side pieces from the blank of the annulus and forming the box from the same blank, I provide a crown on the ring which could receive either a top for a jewel or a stone directly, according to how the box is formed.

Another feature of my invention is the method of fabricating the ring annulus.

In the appended drawing forming part of this application, Figure 1 is an elevation of a ring made to receive a jewel top, sectioned on line l-I, Figure 3.

Figure 2 is an elevation of a ring made to receive a stonedirectly, sectioned on line Z-2, Figure 4.

Figure 3 is a top view of the ring in Figure 1, a portion of the top being removed to show the box formation of the ring to which the top is secured.

Figure 4 is a top view of the ring in Figure 2.

Figure 5 is a plan of a blank'for the annulus.

Figure 6 is a plan of the blank showing it with the raised portions after it hasbeen trimmed, but before it has been drawn.

Figure '7 is a section on line 1'l, Figure 6, showing the raised portion of the blank.

Figure 8 is a top plan View of the blank after it has been drawn and trimmed.

Figure 9 is a bottomplan view of the blank in Figure 8.

Figure 10 is a section on line lll-l0, Figure 9, showing in addition the apertures in the side walls of the side pieces and the slitting of the a facing ends of the side pieces.

Figure 11 is a plan of the blank after the wings have been embossed and trimmed, ready to be bent to form the box, and

Figure 12 is a fragmentary plan of a finished blank for a ring shown in Figures 2 and 4, ready to be formed into an annulus.

Referring to the drawing, I5 is the ring annulus formed of a blank it, see Figures '5 and 6. The blank, when drawn to form the side pieces 58 as shown in Figures 8 and 9, provides a gap l9 between the raised or drawn side pieces l8 and whereat lateral wings I1 are formed. The portion 20 of the blank which spans the wings I! lies in the gap and is in the plane of the blank, as will be seen from Figure 10.

The drawing of the side pieces I8 in the blank 16 will vary in accordance with the type of ring to be made therefrom, but in all cases the side pieces will rise above the blank with a gap therebetween and a portion of the blank in the plane thereof in the gap spanning the wings. The shape of the side pieces and the configuration thereof naturally can and will vary in accordance with the type of the ring desired.

After the side pieces have been drawn as indicated in Figures 8, 9 and 10, the side walls 2! of the side pieces 88 are apertured by slitting as indicated at 22, and pierced as indicated at 23. Thus, side bars or stays 25 are formed in the side walls of the side pieces, making a rigid structure. The slitting at 22, as will be noted, is in a plane parallel to the blank and the gaps formed in the facing ends, and the proximate side walls of the side pieces permit the shaping of the annulus from the blank without interference or resistance from the side pieces.

After the side walls 2| of the side pieces l8 have been apertured, the part 20 of the blank which spans the wings I! and which is located in the gap l9, is apertured by piercing as indicated at 24, thus forming spanning bars 30, best shown in Figure 3. After piercing the blank part 20, the wings are shaped and trimmed, as indicated in Figure 11.

It will be noted that each wing is shaped into a channel 26, see Figure 3, the channelled sides being on the inside of the formed box. This not only gives strength to the formed box but it gives a finished appearance to' the ring and provides a better contact surface for the jewel carrying top 21. It will be noted that the channelled parts of the box section approach the edges of the raised side pieces l8, but there is 'a clearance between them, see Figure 3.

The blank formed as described is then shaped vinto an annulus, as shown in Figures 1 and 2,

and the gap 28 formed can then be closed by soldering.

The ring shown in Figures 2 and 4 and the formed blank shown in Figure 12 disclose a ring that is in every detail of structure identical with that disclosed in the description of Figures 1, 3,

5-11 inclusive. The only formation of the box.

The lateral wings H, in lieu of being shaped as shown in Figure 11, are shaped toa form indifference is in the dicated in Figure 12, which are further distorted in shaping the annulus, as indicated in Figures 1 and 4, to provide prongs 29 to grip a jewel or stone directly. The formation of the side pieces, spanning bars, and the piercing of the side walls of said side pieces, are identical with the description of the other form disclosed in the other figures previously referred to.

From the description it will be seen that when the annulus is shaped, the ring is complete if it is made for receiving a stone directly, But if it is to receive a jewel top, it will be only necessary to select a proper size of top and solder it to the shaped box about the raised side pieces. The raised side pieces, which provide a hollow in the blank under said side pieces, are spanned by the bars 30 of the blank on the inner annular surface of the annulus. They not only span the hollow or the opening in the blank which is covered by the raised side pieces, but the said bars, 30 span the box sections at the gap which is formed by the facing ends of the raised side pieces. The stays 25 formed in the side walls 2! of the side pieces l8 provide/the necessary rigidity with the added attractiveness caused by the piercing and slitting done to form the stays.

It is evident thatthe various portions of the formed annulus can be impressed with decorative designs during the stamping and drawing operation on the blank. Those decorations naturally will vary with the type of ring to be made from the blank.

I claim: I

.1. A method of making finger rings which comprises forming a blank with lateral wings, drawing side pieces on the blank with a gap therebetween so that the said side pieces overlay the blank in spaced relation at the gap, slitting the side pieces at the gap in a plane parallel to the blank, shaping and:bending the wings toward the drawn side pieces to form a box about the gap between said side pieces, formingbars in the blank to span the wings in the'gap, and bending the so-shaped blank into an annulus.

2. A method of ,making finger rings which comprises forming a blank with lateral wings in the central part thereof, drawing side pieces in the blank to each side of the central part of the blank so that a gap is formed between the drawn side pieces and a hollow is formed thereunder, slitting the drawn side pieces at the gap in a plane parallel to the blank, shaping and bending the wings toward the drawn side pieces to form a box about the gap between said side'pieces, piercing the blank'in the gap between the side pieces and the wings, forming the box, and bending the so-shaped blank into an annulus.

3. In a method of making finger rings, steps running transversely of the blankin the gap, 7

and bending the blank into an annulus.
