Abstract: A jewelry chain section and a method of forming the same having a spiral, twisted appearance, involves the winding of a wire on a support and the controlled manipulation of such wound wire during or after removal from the support. The wound wire comprises individual spirals that are twisted relative to each other, such that the individual spirals appear in a staggered formation, with the appearance of a chain section being varied by the number of spirals that are twisted at a particular time and the extent or angular dimension of the rotation imparted to such spirals.

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: Several methods of forming links for use with the creation of rope chains is disclosed, whereby the outer peripheries of such links are contoured prior to assembly into rope chains. In one embodiment, the wire used in the formation of intertwinable links is contoured and then cut into individual, pre-contoured links. In another embodiment, the outer periphery of non-contoured links are individually contoured prior to the intertwining of such links to form actual rope chains. In another embodiment, individual links are stamped with inner and outer peripheries of different shapes. In yet another embodiment, individual links are collectively contoured, preferably after arrangement on a support such as an ice lathe or a mandril. Such contouring can be accomplished by hand, machine or the like. If such links are not already provided with a gap, then a gap can be formed into the links as part of the contouring step.
