  • Patent number: 4763489
    Abstract: A plurality of structures, both alike and disalike, selectively and collectively comprising modular jewelry, may be arranged in various configurations as earrings, a pendant, a bracelet, necklace, belt, or the like. Such modular jewelry elements may be engaged and disengaged with one another without any substantial bending or flexing of attachment features thereof, while still providing a substantial freedom of movement for adjacent interconnected modular jewelry elements. Such modular jewelry is both functional and aesthetically acceptable. The disclosed structure shields from view the modularity of the jewelry, while providing modular elements which are readily reconfigured as desired but which do not become readily disassembled when not desired.

  • Patent number: 4713946
    Abstract: In an ornamental chain, a multiplicity of teeth are arranged in two juxtaposed rows. Each of said teeth has a tooth portion directed toward the other row and arranged to extend between and to interengage with two adjacent teeth of the other row so as to interconnect the rows. Each of said teeth has an end portion on that side of the tooth portion which is remote from the other row. The end portion of each of said teeth of each row comprises two crosspieces, which are spaced apart along the row and extend transversely to a plane containing the chain when it lies on a flat support. A plurality of rings are provided, each of which surrounds two adjacent ones of said crosspieces of adjacent teeth of the same row. The crosspieces and the rings constitute the interconnecting means. Each of the rings connecting the teeth of each row is adapted to interengage with the tooth portion of a tooth of the other row to restrict the movement of the tooth portion transversely to the plane.

  • Patent number: 4679392
    Abstract: A method for forming a garland chain is disclosed, wherein an original chain formed of either long links or of long and short links is worked to produce a garland chain. The garland chain is formed by sliding one link on another so that two attached links are positioned at one end of a long link, and deforming the long link to constrict the central or medial portion, thereby retaining the two attached links at the same end of the long link. Deformation may be applied in the form of crimping, bending or twisting of the links, or combinations of these methods. The deforming methods can be applied to every long link in a chain, or to selected sequences of long links, to create different garland chain effect.

  • Patent number: 4671055
    Abstract: A bracelet for the jewelry and watch making industry, includes rectangular elements connected in a flexible manner by oval links to form several parallel rows adjacent each other. The elements of adjacent rows are also connected with each other by oval links. Each element includes an upper plate and a bottom plate having cutouts that receive the free ends of pillars protruding from the upper plate. The links are of a sufficient dimension to embrace one pillar each of adjacent elements with sufficient play in the longitudinal and transverse direction of the plate, a vertical play being assured by the height of an abutment that keeps the upper plate and the bottom plate at an appropriate distance from each other.

  • Patent number: 4448017
    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.

  • Patent number: 4426854
    Abstract: A jewelry clasp for a jewelry band having chain-link terminals comprises releasably interlockable male and female clasp members. Slip-on connection means are rigidly secured to the distal ends of the male and female members to provide a solderless arrangement for attaching the chain-link terminals of the clasp. Each slip-on connection means is formed from a helix having approximately 11/2 coiled turns so as to form an entrance opening into which the chain-link terminal can be inserted into linking engagement and secured without soldering or special tools. A rectangular blank for making the male clasp member includes an end notch for receiving the helix to be rigidly secured and a laterally projecting leg adjacent thereto adapted to become bulbous when heated and thus form the pin portion of a safety latch.

  • Patent number: 4417437
    Abstract: A watchband is comprised of a plurality of interconnected segments of generally helical shape. The segments are formed of tubular metal rods which may be composed of a noble metal alloy, a copper alloy or stainless steel. The use of tubular metal rods as opposed to solid metal rods results in a reduction in materials costs and a lighter weight watchband. The watchband is manufactured by winding a tubular metal rod on a mandrel into a generally helical shape, cutting the helically-wound tubular metal rod to predetermined lengths, and connecting together the lengths in lengthwise juxtaposition so that the coils of one length partly overlie the coils of adjoining lengths to thereby form a watchband comprised of interconnected tubular metal rod segments. By using tubular as opposed to solid metal rods, the annealing process normally required in order to wind the rod into helical shape can be eliminated.
