CHAIN.

Application filed December 15, 1926. Serial No. 154,929.

This invention relates to an improved construction oil. ornamental chain for personal wear; and has for its object to provide simple and effective means for adjoining the links of the chain together without the use of solder.

A further object of the invention is to provide a construction of decorative chain, the links of which are of a desirable ornamental shape.

lVith these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

1.11 the accompanying drawings:

l igure 1 is a plan view of several connected links.

Figure 2 is a side elevation thereof.

Figure 3 is a detailed perspective view showing the body of one of the links.

Figure t is a perspective view of a blank for one of the connecting members.

Figure 5 is a perspective view showing the connecting member bent to substantially opcrating position.

Figure 6 is a perspective view of one of the constructions of links complete.

Figure 7 is a central sectional view of the same.

Figure 8 is a plan view of another different link of the chain.

Figure 9 is a central sectional view through several of the connected links showing the connected members before swaged into linished position.

Figure 10 is a modified construction of the links shown in Figures 6 and 7.

Figure 11 is a central sectional View of another modified form and Figure 12 is a central sectional view of a still further modified view of the link shown in Figures (5 and 7 In. the construction of ornamental. chains for personal wear such as watch chains key chains and the like, it is found desirable to provide a construction in which soldering is eliminated in order that the difl'erent colors of parts of the links of the chain may be used. and not detrimentally all'ected and yet a construction in which the different links of the chain may be made in an ornamental shape to be attractive in appearance,

and in order to accomplish this, I have provided a chain of two different constructions of links arranged. with one construction alternating with the other throughout the chain; and the follmving is a detailed description oil. the present embodiment of this invention showing one arrangement of parts by which the links of the chain may be formed to accomplish these desired results.

lVith reference to the drawings, 10 designates a link of one construction which. is of bar form with openings or eyes ll at each of its ends which may be cut in the shape shown from sheet stock so as to be seamless. i

A. second construction of link which is designated 12 is so formed as to join the links 10 together and alternate therewith throughout the series of links of the chain. This second construction comprises a body 13 having longitiulinally disposed diametrically opposite grooves 14 on either side thereof with an opening or recess 15 intermediate the ends of this bar and located in said grooves A U-shaped member 16, which may be formed from a wire blank 17 or cut out from sheet stock in the shape shown in Figure 5, is passed through the opening 11 and positioned with its arms 1.7 lying in the grooves 14: of the body. The ends 18 of these arms are bent inwardly toward. each other into the opening or recess 15 in the body as shown in Figure 9, after which the links are swaged in a swaging ma chine to close thi arms 17 tightly against the body and in the grooves thereof, illustrated in Figures 1, 2, 6 and 7 thus securely joining the links of the chain together and preventing a separation thereof under ordinary longitudinal strains.

A variety of portions oi? the link 12 may be provided as illi'istrated in Figures ll), 11, and 12, in which openings 20 in the body 21 may be spaced apart, as illustrated in Figures 10 and 1.1., and the coimecting members 22 may be oi. shorter formation. and as illustrated in Figure 11. additional. ornamental pieces 23 may be attached, or it desired a fancy shape of connector member 24; may be associated with the body member 13, as illustrated. in Figure 12.

It will also be apparent that an opening or recess 15 or 20, need not necessarily exornamental chain in which the parts of alternating links are duplicates one of the other thus providlng a chain which may be. made n quantities at a minimum cost and yet one in which different parts of ditterent colored gold and these different colors he unal'l'ected in attaching the same together as the necessity of the use of solder or heat is eliminated.

The foregoingv description is directed solely towards the construction illustrated, but I desire it to be understood that l reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the. terms of the appended claims.

I claim: I

1. In an ornamental chain, a link member having a'body, a recess therein intermediate its ends, and two U-shapcd connecting members extending along said body and engaging the sides thereof, and having connecting portions extending into said recess and center loop portions extending beyond the body to form connecting loops for interconnection with adjacent chain link.

2. An ornamental chain comprising links of two diil'Icrent constructions alternately arranged in connected series one construction of link being of bar torm with spaced openings one adjacent each end, the other of said constructions comprising a body having dianietrically oppositely disposed grooves extending longitiulinally thereot with an opening thercthrmigh connecting said grooves, oppositely disposed U-shaped members having their arms in said grooves and extending through the end opening of the adjacent bar links, the ends of the arms of said members extending toward each other into the opening in said body to lock the parts together and the links againstseparation.

In testimony whereof I athx my signature.

WILLIAM Fons'rNEn.
