Patented Oct. 8 1929 UNITED STATES FFICE- CORPORATION, OF IRVINGTON, NEW JERSEY, A CORPORATION OF NEW JERSEY CHAIN Application filed April 14, 1925. Serial No. 22,986. V

This invention relates to an improved con- :struction of ornamental chain for personal wear, and has for lts ob ect to provide slmple :andelfectlve means for applying ornamentaornamental block and the arms embracing (the same, wh ch twisting action serves to more closely bind or force the arms into the grooves of the block.

A still further object of the invention consists in the connecting of these elongated links by connector links of S-shape. These connector links being of a character to strongly resist an opening strain thereon so as to firmly secure the long links together without the necessity of soldering the ends of the S-link.

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.

In the accompanying drawings:

Figure l is a side elevation illustrating a short length of chain constructed of elongated links of different characters connected by S-links.

Figure 2 is a perspective view showing one of the grooved block ornaments as removed from its elongated loop link.

Figure 3 is a perspective view showing one of the elongated loop-links.

Figure 4: is a perspective view showing one of the elongated loop-links with its arms embracing an ornamental block mounted there in.

Figure 5 shows the block as mounted between the arms of the loop-link, both being twisted a one-half turn.

Figure 6 is a side elevation of the S-shaped link with its ends open.

Figure 7 is a side elevation showing the S-link withits ends closed to connect adjacent loop-links together.

It is found in the construction of ornamental chains for personal wear, of advantage to form a variety of styles of ornamentation on the links thereof; also it is found of advantage to form certain of the links separately so that they may be finished in groups and ornamented or treated to receive different colors such as green gold, red gold, yellow gold and white gold, and after these groups have been so treated'and colored, to be able to connect the differently colored links in different Ways to produce a variety of different artistic effects, and to accomplish this in a simple and effective way,'l have formed a set of elongated loop-links which may be treated in a certain way, and I have provided a set of ornamentations for these different loop-links which, in themselves, may be treated in a different way from that of the loops and subsequently inserted by being snapped into position between the arms of the loop links and subsequently embraced by the arms of the loop-links without the use of solder. f In other instances, I may, after inserting the ornamental link between the arms of the loop-link, twist this loop-link with its filler block to present another form of ornamentation, and it"is found of advantage to connect these differently-treated links together by a connector link which is so formed as not ts require its ends to be soldered, and to accomplish this I have preferably formed this connector link in an S-shape, the wire of the S being hardened or made very stiff by the inherent qualities of the wire so as to tenaciously resist an opening action and so be as strong as the other loops of the link even though its joints remain unsoldered; and the following is a detailed description of the'present embodiment of my invention by which these advantageous results'may be obtained With reference to the drawings, 10 designates the elongated loop-link which maybe WILLIAM ronsrnnn, or rnvmeron, NEW JERSEY, nssrenon T0 FORS'TNER crumb made of any desired wire and of any desired size and dipped or treated to obtain any desired coloring effect.

In order to provide a simple and effective ornamentation for this link, I have formed a block member 11 which is preferably of a length less than that of the link.

This block is preferably provided with longitudinally-disposed grooves 12 on its oppo- 'si-te edges and is adapted to be snapped between the arms 13 of this long loop, and these arms are then pressed down into the grooves 12 to secure and bind the ornamentation therein. As the length of this block is less than that of the link a space 14 is left at op- ,posite ends thereof providing eyes or spaces through which the connecting link 15, presaently described, is passed. These blocks 11 may be finished or treated independently of .the link and dipped or colored differently from that of the loop, if desired, and when snapped into position be retained therein ,without the use of solder, thereby preventing discoloration of the parts which would be the oaseifsoldering heat should be applied theret0.

Insome instances, after this block has been positioned in the loop, I twist this loop and .block to an angle of about 160, if desired, as

.30 best illustrated in Figure 5, to provide fur- .ther ornamentation for the link.

In connecting these elongated loops together, Ipreferably employ an S-shaped link 15, .the wire of which maybe of any shape .in

cross section but which is preferably formed of very hard and stiff material and has ,preferabl-y as great or greater resistance than anyof the-other links of the chain so that when its ends 17 are closed upon the {A0 shank 18 thereof its great resistanceto a separatingstrain will preventit from opening and so be as strong as any of the-other soldered-or integral links of-the chain, it sbeing understood that the shank portion of the .S- .45 s ha,-ped portion being of a continuous wire I serves to greatly resist an opening action on the link .as this continuous member receives .one-half ofthe opening strain which may be :applied to both of the eyes thereof, one opuar- 7 ter being takenby one loop, and the other .quarterby the opposite loops. 7

Itis-also found of advantage to connect the endsiofathis wire so asto liesquarely against opposite sides of the shank thereof so as to .55 reduce the joint opening to the minimum.

, .My improved form of chain is very inex- ,pens'iveto constructas it may be assembled .automatically by machinery. This chain also Ilends itself-to presenting a great variety of colorsand ornamentation and may be entirely.assembled by machinery and without the .use ofsolder.

The foregoing description is directed solely-itowardsthe construction illustrated, but

i ,I'desire it to be understoodthat I reservethe 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 claim.

I claim:

A chain having elongated loop-links with bendable side arms, and ornamental metallic members of a length slightly less but of a width greater than that of the link and of an approximately rectangular cross-section but having two diagonally opposite corners cut away to provide longitudinally extending grooves, the angular relation of the remaining corners of the cross-section of the members causing each member to enter and snap between the side arms of a loop link and lie therein throughout its length, said arms being bent. to lie in the grooves, and links extending through the spaces between the ends of said members and the loop links'to connect said loop links together.

In testimony whereof I affix my signature.

WILLIAM FORSTNER.
