Abstract: A chain link of hollow construction and substantially uniform thickness, for intertwining with other chain links to form a jewelry chain, has a non-annular cross-section throughout the link with the cross-section being symmetric along a centerline plane through said cross-section. The cross-sectional shape of the link preferably has on each side of the centerline plane, at least two sides that meet at a point of inflection. On each side of the centerline plane, at least one side preferably converges toward said centerline plane. A reduction in manufacturing costs and precious metal used to form the links and therefore the chain is realized by using a non-annular cross-section having such constructional qualities.

Abstract: A jewelry link made from square crossectional metal wire has a C-shape when the link is bent within a specially configured clamp over a mandrel, wherein the formed C-shaped links are diamond shaped in cross section. The links further have an outer circumference at their widest point formed by one of the four corner seams of a hollow or solid square wire, which is rotated 45 degrees onto one of its straight longitudinally extending edges before being bent around a mandrel. In that manner, the link is considerably wider than a link formed from square wire which is wrapped upon one of its surfaces over a mandrel.

Abstract: A non-annular, hollow chain link is provided with a gap and is capable of being intertwined to form a jewelry rope chain. The gap faces the widest dimension of the link, and faceting surfaces are preferably disposed adjacent the gap. When compared with an annular, prior art link having a diameter that is equivalent to the widest dimension of the non-annular link, the faceting surfaces present a greater faceting surface area than the faceting surfaces of such annular, prior art link. Thus, a faceted rope chain formed from such hollow, non-annular chain links will have a greater faceting presence and appearance than an equivalent rope chain formed from annular chain links.

Abstract: A method and apparatus for making faceting hollow or solid jewelry chains involves subjecting the chain wrapped around the drum of an ice lathe to the rotary motion of a cutting wheel essentially perpendicular to the length of the drum. The cutting wheel has a plurality of teeth and is fitted at the end of an arbor held by two bearings clamped to a flat steel platform which is adapted to the advance mechanism arm of the ice lathe. An electric motor mounted on the flat platform turns a shaft that is fitted with pulleys to allow the rotary power of the shaft to be transmitted to the arbor. The direction of the turning of the cutting wheel determines whether the cutting wheel is used to flatten and facet a hollow chain link or to cut a solid chain link. The cutting wheel's diameter and quantity of teeth is variable.

Abstract: The present disclosure provides a secure yet easily adjustable link design for use in interconnected link jewelry and watches. A link for a bracelet is disclosed that allows for easy adjustment in the length of the bracelet, utilizing a bar and spring system. To remove a link from the bracelet, the links must be at approximately a right angle, force must be applied outwardly to the link with the spring from which a bar is to be removed, and the links easily separate. Similarly to couple links, the links must be at approximately a right angle. When the links are at approximately a right angle, the bar of the first link can enter the spring of the second link. When the links are at any other angle, the bar is secured in the spring and cannot be removed or dislodged. The disclosed bar and spring system allows for a secure yet easily adjustable link system.

Abstract: A method of diamond cutting or faceting hollow link jewelry chain by arranging a chain on an ice lathe support, completely freezing the chain on such support and moving a blunt instrument across such chain to produce flattened links. The pressure of the blunt instrument against the frozen chain simultaneously scrapes off the ice and flattens the links, thereby avoiding the requirement that the portion of the links that are to be faceted be initially unfrozen. The blunt instrument may be a so-called “finger of steel”, which can be sharp, pointed, rounded, arcuate, smooth or the like. A variety of faceting formations can be realized depending on the movement of the blunt instrument across the outer surface of such chain.
