1 1 l 10 Claims. l The present invention relates to articles of `jewelry and 'particularly to improvements in flexible Achains orlinkages having hollow boxtype links.

One of the objects of thepresent invention is to provide an article ofthe type indicated which may be constructed of relatively light stock while being strong and durable in use. *Another object of the invention is to provide an article of thetype indicated having hollow links of l `improved construction forV mounting Xgemslor other ornaments.

`Anotherobject of the `invention is to provide hollow boX-linksfof the type indicated having a minimum number of parts adapted to be conveniently constructed from sheet-metal stampings. l

Further objects of the `improvement are set forth in the `following specification which describes, by `Way of eXamplea preferred form of jewelry chain or linkage as illustrated by the accompanying drawing: In the drawing:

Fig. 3 is a side elevational View kof a portion of the chain with one of the box-linksillustrated in section to show the connecting loops at its ends engaging shoulders on the gem-supporting frame to hold the latter in position in the bodymember; i n Fig. 4 is a transverse sectional view taken on line 4--4 of Fig. 2 showing the gem supported by the frame and the frame supported by the inturnedside walls of the link; and

` Fig.'5 is a perspective view of the parts of one of the hollow box-links shown in disassembled relationship. l

It is desirable in the jewelry art that the links of chains and bracelets be designed to give the appearance of "weight andsolidity, while at the same time being of light skeleton construction to save stock; especially when-the links are made of precious metals. For this reason prevailing styles of bracelets and'chains are con- "structed, at least inv part, from hollow links. and -the present invention provides a hollow box-type sides. V

frame I2 is struck'up or embossed to provide,

`link of novel construction with means for setting f2 a gem in an opening in its top wall. l.

Referring now to the drawing, the jewelry chain or linkage herein illustrated is composed Vof ornamented box-links I incorporating the novel features of the present invention, alternating with looped connecting links 2. Each box-link I comprises a body-member 3 0f sheetmetal blanked out and formed to provide a crowned -top 4,' depending side walls 5, .and end flanges S folded toform opposite connecting loops. The top wall Il has an opening I0 of `any suitable contour to expose an ornament II mounted or set in the body-member 3. Although the o-rnament I I is herein illustrated in theform of a gem or jewel, it will` be understood .1, d

that it may take other forms. The gem orother ornament II issupportedV in the body-member 3 by means of an inverted tray-likeY frame I2 blanked from sheet-metal and folded toprovide a bottom wall I3 and upstanding side and end f;

flanges I4 and I5. The arrangement ispreferably such that the ends of theend flanges 1510i the frame .I2 abut the inside face of the top,` wall 4 of the body-member 3 `adjacent the sides of the opening I0, while the side flanges `I4 en-,`

member 3 by inwardly-folded terminalportions` 'I at the bottom of the side walls 5 and thefends Vof the looped flanges 6, these several parts, en-

gaging the bottom wall of the frame l,on four Preferably the botto-1n wall "I,3""o"f the pairs of oppositeshoul-ders I'I and I8 which abut and interlock with the ends of the bent portions I of the sidewalls 5 and the ends of the looped flanges 6 to positively `hold theframe in position in the body-member. most clearly in Figs. Lland 5,.-the bottom wall I3 has an embossed table I6 of rectangular outline to form the pairs of opposite shoulders Il and I8. The shoulders I'I and I8 are of a depth equal to thethickness of the end portions 'If and flanges B so that when the latter are interlocked with the shoulders they forma continuation of the bottom face ofthe table. I6 to provide a smooth finish for the bottom `of the link I. l I

It has been stated that the frame I2 isheld from longitudinal movement in the body-member 3 by the engagement of the ,ends of the looped flanges 6, but it is also to be noted that As illustrated.

the frame is prevented from such movement by the peculiar formation of the top wall of the body-member where the iianges are bent downwardly or inclined towards the bottom of the link. That is toV say, even when the ends of anges, as indicated most clearly in Fig. 3 of,

the flanges 6 are bent downwardly away from the bottom of `the frame I2 the frame will still be held'from longitudinal movement in the bodymember by the inclined bent portions of the the drawing. This particular feature of construction provides that when the loops atithe end of the link .are opened to increase or reduce the length of the chain or bracelet, for example in fitting the bracelet to the wrist of the wearer,

the frame I2 will not be loosened in the bodymember to shift its position longitudinally thereof.

The connecting links 2 may be of any desired ,configuration, being preferably formed of sheetmetal stock and generally curved or bowed to ,onfoijmto the contourI of the wrist of the wear- .er of: the .bracelet Each of the links 2 has a .central opening 20 to form a loop with side -bars 2l ,and connecting webs 22 at its ends. The

links 2 are pivotally connected to the ends of a pair .offthe box-links I, the opposite bars 22 of .teach link 2 passing through the adjacent looped i .iianges'I onthe box-links. The connecting links V2 .thus pivotally connect the series of box-links I to` provide an articulated chain or linkage. The individual links Vof the chain or linkage are assembled by a preferred method which congsistsin first inverting the body-member 3 of a 85 -box-link I so that the end flanges 6 and side walls -75 project upwardly as illustrated in Fig. 5, prior to their` being folded inwardly. The gem or other vornament AII is placed in the opening I0 so that it is engaged adjacent its edges by the /edgesof the top wall 4 surrounding the opening Ill and-a pairof connecting links 2 are looped =aroundthe upstanding iianges Ii. The'frame I2 `is l'placed in thebodyo-membe'r 3 to engage its sideflanges I4 with the gem or other ornament II adjacent,the edges of the latter as illustrated 1inFig. f1. The end portions 1 of the side walls and the end flanges 6 are then folded inwardly into engagement with the pairs of opposite shoulders I I and I8 on the bottom ofthe frame I2 to 4retain the latter inposition in the body-member v-v3. `The folding of the end flanges 6 forms closed `,loops'iwhicnh embrace the bars 22v of the connectinglinks 2 to pivotally connect the latter tothe box-link I. The interlocking engagement fof themend portions 1 of the side walls 5 and the ends ofthe flanges 6 with the shoulders I1 and I8 on the bottom of the frame I2 holds the iframe against movement either laterally or longi- ,ltudina'lly o f the hollow link I. It will also be Vfobservel that the end portions 'I and flanges 6 forma continuation of the bottom wall of the table I6, gi,ving the hollow box-link I a solid fin- 4ished appearance. It will be understood that the v box-links I and conecting links 2 are successively ,added until y,achain or ,linkage of suitable length whas beenformed and that the operation of bendling,tl ie endportions 'I of the side walls 5 and rthe,endflanges 6 ispreferably performed in a suitable machine fixture although it may be T 0 performed manually.

75 understood, however, that the invention may be embodied in a chain or bracelet having box-links without the gem or jewel setting and ornamented in other ways as for example, by embossing, engraving, enameling or any other method such as well known in the jewelry art. It will also be observed that the box-type links are of simpleV construction having a minimum number of parts and yrequiring `a number of operations to assemble them together to form a chain or linkage.

While the invention is herein shown as em- `bodiedin a preferred form of chain or linkage construction, it is to be understood that various modifications may be Ymade in the structure and arrangement of the parts of the linkage without departing from the spirit or scope of the invention. f Therefore, without limiting myself in this respect, I claim:
