Abstract: A rope chain formed by intertwining links of a U-shaped cross-section is disclosed, which links are formed from a wire having an interconnecting upper portion, a pair of substantially straight legs extending downwardly from the interconnecting portion, and a substantially open bottom portion or seam opposite said interconnecting portion. The substantially straight legs, results in a rope chain having a full-bodied appearance and a snugger interfit between intertwined chain links. The U-shaped configuration can produce a rope chain that uses less precious metal than if the cross-section of the wire were annular and the links themselves were of annular, toroidal configuration.

Abstract: An improved jewelry chain loop element and method of assembly into single, double, triple, etc., chains in which the links are formed from soldered wire rings. One segment of each ring is crimped together so that the ring is formed into an approximate teardrop shape with one end having parallel wires and the other a loop. The loop may be flattened. Then an ornament, such as a bead, tube bezel, cup bezel or other ornament is formed or secured on the crimped end to form a combined fastening means and tip ornament. The crimped segment is bent upward at a 15-60 degree angle either before or after the bead or ornament is formed. The individual links are then assembled into the chain by placing the ornament of one link through the remaining loop of the next adjacent link and the loop crimped about the adjacent link's ornament. Alternatively, teardrop-shaped links may be cast as single links or as tandem (double, triple, etc.) links. A number of completed chains or single teardrop link elements may be connected (e.

Abstract: A jewelry link in the form of an elongated loop capable of holding and displaying a number of precious stones or the like. The link has a closed U-shaped ring at one end and a corresponding hole at the other end, so that the ring of one link may be inserted into the hole of an adjacent link. Each link has a deformable hook secured adjacent the ring-receiving hole, so that when the U-shaped ring of an adjacent link is inserted in the hole, the two links can be locked together by pressing the deformable hook so that it interlocks with the inserted ring. By this means links can be added to a bracelet or necklace as the wearer is able to purchase them; and in similar fashion additional precious stones can be added to each link as desired.
