Definitions

  • This invention relates to a hand-made chain, specifically jewelry chain of the type known as a rope chain.
  • the method for making the same is readily derivable from the construction.
  • the basic construction element, or component, of such rope chains is a ring formed of a solid or hollow wire, usually of precious metal, e.g. 14 karat gold.
  • the ring 1 shown in Figure 1 has an opening or gap 2 formed therein. This gap 2 has a narrow dimension 3 at its inner diameter and a wider dimension at its outer diameter.
  • the solid wire forming the ring ( Figure 2) usually has flattened sided and rounded ends 5 which give the ring 1 a major diameter (d w ) 6 and a minor diameter 7.
  • the cross-section of the wire forming the ring 1 may also be of generally circular cross-section.
  • the gap 2 of ring 1 is substantially larger than the minor diameter 7 and is slightly larger than the major diameter d w at its narrowest dimension 3.
  • a multiplicity of such rings 1 are intertwined to form, in outward appearance, a double helix, as shown in Figure 3, which is the format for a standard rope chain.
  • Figure 3 is the format for a standard rope chain.
  • the ring 1 used for the chain should have an inner diameter (d i ) slightly more than X times greater than the major wire diameter d w 6, and X equals 3 or an odd number greater than 3, e.g. 3.4. See US-A-4,651,517 for a detailed discussion and serving as a basis for the preamble of claim 1.
  • d i inner diameter slightly more than X times greater than the major wire diameter d w 6, and X equals 3 or an odd number greater than 3, e.g. 3.4.
  • the relative orientation of the rings forming the rope chain is important.
  • the a ring is initially oriented (manually) so that its gap, designated 20a, lies in a predetermined direction, e.g. facing generally upwardly, as in Figure 4 .
  • the second ring of this assembly designated the b ring, is passed through the gap 20a of the a ring, with the gap 20b of the b ring facing downwardly at about 180° removed from the a ring gap 20a, as shown in Figure 5.
  • the a and b rings are juxtaposed and intertwined so that they lay against each other, with the periphery of the b ring lying against the periphery of the a ring, to the greatest extent possible, thereby creating a relatively large central opening 30 with the pair of intertwined abutting a and b rings.
  • the plane of the a ring lies in parallel to the plane of the paper, and the plane of the b ring is slightly skewed from the a plane.
  • the gap 20c of the third ring c is then passed through the gap 20b of the b ring and over the minor diameter of the a ring and laid angularly against the a and b rings, the gap 20c of the c ring lying in the same orientation as the gap 20a of the a ring, and as shown in Figure 6, but with its plane more greatly skewed than the a and b rings.
  • a central opening 30a still remains within the now three intertwined rings a, b and c.
  • the planes of each of the rings differ from each other by perhaps about 20° because of their angular abutment. In the case where X equals 5, the planes of the rings would differ from each other by about 15°.
  • the gap 20d of a fourth ring d is now passed over the a, b and c rings, through the central opening 30b, and thereby envelopes the a, b and c rings.
  • the c ring is laid against the other rings (a-c) and its plane lies apprxoximately 20° from the plane of the c ring.
  • the gap 20d of the d ring is disposed in the same orientation as the gap 20c of the d ring.
  • the adding on of an additional assembly of four rings is a repetition of the orientation previously described with reference to the a-d series, but the planes of this second assembly lie at approximately 90° to the planes of the respective rings in the first assembly.
  • the gaps of the first and third ring additions of a second ring assembly abut the previous first and third rings, and the second and fourth rings pass through the gaps of the previous second and fourth rings and that the relative orientations of the gaps of the rings alternate between adjacent rings about 180°.
  • the operator he or she is always alternating the gap orientation while intertwining each additional ring.
  • each assembly of rings comprises at least one group of two or more adjacent rings having their gaps in the same orientation, said at least two or more adjacent rings being fixedly attached to each other, each of said at least one group of two or more adjacent rings being also fixedly attached to another ring having
  • Manufacturing rope chains according to this invention with ring assemblies having at least one group of two or more adjacent intertwined rings oriented with their gaps in the same direction is made possible by fixing the similarly oriented adjacent rings to one another, so that each group of such similarly oriented rings can be considered and treated as if it were a single ring with a single gap.
  • the precious metals for fine jewelry rope chains of this invention may be gold, platinum, silver and their alloys.
  • rings a, c, aa and cc have their gaps 40a, 40c, 40aa and 40cc, respectively turned 180° with respect of the gaps of rings b, d, bb and dd.
  • Rings d and dd envelop (50, 51) the previous three rings of their respective assemblies.
  • This arrangement of rings requires that the groups of rings, b-c-d- and bb-cc-dd, be soldered S together to form single units.
  • the last ring d and dd of each assembly is, in this case, soldered S1 to the first ring as, ee of the next assembly.
  • the number of rings which must be manipulated for each assembly and turned 180° with respect to the previous ring is only one, which is a 2/3 saving of time for this type of manipulation.
  • this arrangement can save approximately 18-20% of labour costs in the manufacture of such a rope chain. As will become apparent, this labour saving increases relative to the prior art method as the number of adjacent rings having the same gap orientation in a group increases.
  • FIG. 10 this schematically illustrates a section of rope chain having a ring diameter to cross-section ratio of 4+:1.
  • Each ring assembly comprises 5 rings.
  • rings a, d, aa and dd have their gaps in one orientation and rings b, c, e, bb, cc and ee in the opposite orientation.
  • Rings b and c form one group and rings bb and cc form another group of adjacent rings having similar gap orientations.
  • the rings in each group, b-c and bb-cc are soldered to each other S, and the groups are soldered S1 respectively to rings d and dd, which have their gaps oriented 180° from the rings in the groups. Rings e and ee envelop the preceding rings (54, 55) of their respective ring assemblies.
  • each ring assembly comprises 6 rings.
  • rings a, d, aa and dd have their gaps in one orientation and rings b, c, e, f, bb, cc, ee and ff in the opposite orientation.
  • the groups of adjacent rings b-c, e-f, bb-cc and ee-ff have similar gap orientations.
  • the rings of each group are soldered S together and the groups in turn are soldered S1 to rings d, aa and dd respectively, which have their gaps oriented 180° from the groups. Rings f and ff envelop their respective ring assemblies (56, 57).
  • This arrangement of rings provides a beautiful rope chain with less labour cost than is possible with the arrangement disclosed in U.S. Patent 4,651,517.
  • Figure 12 illustrates another variation in the orientation of the rings in an assembly having an inside ring diameter to cross-section ratio of just over 5:1.
  • this arrangement there are groups of three adjacent rings (b-c-d and bb-cc-dd) having the gap in the same orientation for each ring assembly.
  • These rings are soldered together S and the groups b-c-d and bb-cc-dd are soldered S1 to another ring e and f respectively in the assembly having an opposite gap orientation.
  • Rings f and ff envelop (58, 59) their respective ring assembly.
  • Figure 13 illustrates a ring arrangement having an inside ring diameter to cross-section of just over 6:1 comprising 7 rings in each assembly.
  • This arrangement illustrates two ring assemblies, each with a group of four adjacent rings, b, c, d, e and bb, cc, dd, ee, having the same ring gap orientation soldered S together. These groups are further soldered S1 to rings having opposite gap orientations f and ff respectively.
  • the time saving with respect of ring manipulation in this arrangement is even greater than in the previous illustrations.
  • This invention makes it possible to manufacture fine jewelry rope chains with assemblies where X may be an even or odd number having from two to X number of adjacent rings with the same gap orientation.
  • the ratio of the ring diameter to ring cross-section is preferably X.1 to X.X and most preferably X.1 to X.7 wherein X is a number equal to 3 or more. Preferably X equals 4 to 7.
  • hollow rings can also be used to provide further cost saving, since less precious metal is then used.
