  • Patent number: 5542245
    Abstract: This disclosure relates primarily to the making of compressed single and double arrow jewelry chains, of precious or non-precious metal, and other unique surface designs, from open link chains wherein the regularly repeating apertures of the prior art chains have been substantially eliminated, thereby providing an exceedingly smooth look and silky feel to the completed chain. The compressed chain of this invention is made by first precisely aligning two or more open link chains together, side by side, along a single longitudinal axis, welding, as by soldering or brazing, the aligned open link chains, and subjecting the thusly aligned chains to a series of incremental compression steps, along the longitudinal axis of the aligned curb link chains. In this way, the regularly repeating apertures of the aligned open link chains are substantially eliminated while creating, as in the case of the use of single curb chains as the starting point, novel non-apertured arrow designs.
