Other objects of the invention will in part be obvious yand in part hereinafter pointed out.
The invention accordingly consists of features of construction, combination of elements and arrangement of parts which will be exemplified in the constructions hereinafter disclosed, the scope of the application of which will be indicated in the claims following.
IIn the accompanying drawing in which illustrative embodimentsof the invention are shown:
Fig. l is a perspective view, partly in phantom, showing a spirally wound self-ceiling chain -construction embodying the invention forming a piece of jewelry resiliently retained by spring action of the interconnecting links thereof against unwinding to serve either as a ring, a bracelet or other chain incorporated device, as is clear from Figs. 2 and 3.

Fig. 12 is a side elevational view similar to Fig. 6 but made of links shown in Figs. 9 and l0.
Heretofore, chains and chain constructions have been made with linkages comprising interconnected links thereof joined for practically free and unrestricted swinging movement with relation to each other in at least one direction, or litted for limp or frictionally retarded relative movements. In the present invention, there is provided an improved self-coiling linkage construction having a constant spring influence action effective against forces applied or present to unwind said self-coiling linkage from a normal initial self-coiled position.
Referring in detail to the drawing, 20 denotes a selfcoiling chain construction embodying the invention adapted for the jewelry trade and, as shown in Fig. 1, may comprise a resiliently retained spring acting linkage 21, links 21a of which are so constructed, shaped, interconnected, arranged and positioned to act with resilient force against unwinding, that is, uncoiling or uncurling from self-coiled fully or partially spiral wound conditions, as shown in Figs. l, 2 or 3, to stretched flat positions, as is clear from Figs. 4, 5 and 6. `Opposite ends of linkage 21 may be provided with suitably shaped finishing ornaments, for example, ornamental terminals or nials 22 to trim and enhance the appearance of chain construction 20.
Links 21a each may be made of any .suitable material having an inherent degree of resiliency, that is, elasticity, to bending forces and, as here shown when used for articles of jewelry, said links 21a may be made ofmetals, such as, gold, gold alloys or resilient base metal alloy suitable for plating with precious metal.
Each link 21a may be fabricated from wire stock and assembled into a chain construction in the well known manner to have component under-looped portion 2lb and an adjoining upper-looped portion 21C bent across the middle of the link 21a to extend in an overlying relation with respect to the under-loop portion 2lb. As here shown, said link portions 2lb and 21e may be joined through a pair of spaced apart bights 21d provided therebetween and forming a hook engaging means at one end of each link 21a, the opposite end of the latter forming a double eye-coupling supplied by aligning sections 21e and 21f of loop portions 2lb and 21o, respectively, as is clear from Figs. 6, 7 and 8.
The above described linkage 2i also permits lateral movement between links 21a, as is clear from Fig. 2 and shown in the full and dot and dash lines in Fig. 3.
In fashioning links Zla from circular wire stock, a decorative appearance may be provided for chain construction by stamping an ornamental design on the upfacing surface of one of the link portions, such for example as seen in the drawings provided on the fiattened under-loop portion 2lb.
A chain construction also embodying the invention is shown in Figs. 9, l0, ll and l2 to comprise a modified linkage 31 formed of links 31a which may be fabricated by stamping link blanks from sheet metal stock. As seen from Figs. 9, l0 and 1l, link blank 30 comprises a pair of loop portions Sib and Sic having elliptical or oval shaped openings, loop portions 32h and 31e being interconnected by a narrow neck which when folded into link 31a forms bight 31d which is comparable to the pair of bights 21d in link Zla. Links 31a in assembly form linkage 31 in which loop aligning sections 31e and 313 of loop portions 3112 and 31C, respectively, coact with bight Sid of adjoining link 31a in the same manner to give the same resilient self-coiling properties described hereinbefore with reference to linkage 21.
As is well understood in the art and as indicated in Fig. 9, linkage 3l may be assembled by inserting one of the loop portions 311 or 31C turned at right angles through the large diameter of the openings in link Sla, loop portions 31h or 31C being proportioned for that purpose, and then folding said loop portions 31h and 31C to bring loop sections 31e and 31j into proper predetermined spaced relation and also to properly shape bight Sld for co-action with loop sections 31e and 3M of the preceding link 31a.
Links 21a likewise may be provided in a flat unfolded condition similar to link blank 30 and assembled by inserting the smaller upper-loop portion 23e through the openings in loop portions 2lb and 21e and then folded into proper shape and configuration to form linkage 2l.
As will be clear from Figs. 4, 6, 7, l0 and 12, links 21a and 31a may be folded so that loop aligning sections Zle and 31e of under-loop portions 2lb and Slb, respectively, project beyond loop aligning sections Zlf and 3U of upper-loop portions 21C and 31C, respectively, in order to provide a minimum over-all thickness at the end of the links engaged in bights 21d and 31d, respectively, for more eicient coaction therebetween.
The utility of the invention will now be apparent.V Links 21a and 31a are assembled into linkages 21 and 31 of desired length to the ends of which may be added finials 22 to form self-coiling spiral finger rings, bracelets or other jewelry items as illustrated in Figs. 2 and 3. Linkage 21 when made of solid gold forms particularly attractive articles of jewelry or when made of a resilient brassniay be plated with gold, silver or rhodium for use in popular priced costume jewelry.
Loop portions 2lb, 21e, and 3111 and 31e may be made square or rectangular in shape in which case the lateral movement between the links will be limited and coiling will be confined to a single plane.
It is thus seen that there are provided resiliently coiled chain constructions and links therefor whereby the several objects of this invention are achieved and which are well adapted to meet the conditions of practical use.
As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiments above set forth, it is to be understood that all matters herein set forth or shown in the accompanying drawing are to be interpreted as illustrative and not in a limiting sense.
Having thus described my invention, I claim as new and desire to secure by Letters Patent:
