. 6 Claims.

This invention relates to bracelets or the like, and to a method of making the same.

More particularly, the inst-ant invention relates to bracelets of the general type disclosed in the col-pending applicationof Leslie Kreisler, Serial No. 673,691, filed May 31, 1946.

It is the primary object of the present invention to provide a bracelet, .or the like, which is fabricated from individual spiral links that are joined without any special connecting elements, and which assumes the appearance of obliquely interwoven, continuous bands rather than that Of joined spiral links.

it is another important object of the present invention to devise a method of fabricati g racelets ofwthis typ which lends it elfto hi hly fiicient mass productionof the brace et at e t mely low cost. 7

The above and other objects, feature advanta es of the p esent nvent o l be fu l der toed f omthe renew n d cr p on ns ered in connection with the accompanying illustra tivedrawings.

After removing the compressed link assembly 32 from between the rams 36, and the pins 23 from the assembly 32, the bracelet is completed, and it may then undergo a plating process or any other em-bellishing process.

In compressing the link assembly 32 as described, the same is elongated longitudinally as follows clearly from a comparison between Figs. 1 and 2 and also between Figs. 3 and 6. The link assembly 32 is, during its compression, elongated longitudinally since the links 22 thereof are prevented from expanding transversely of the assembly 32 by the retainer platens 46 (Figs. 3 and 6). By preventing expansion of the links 22 transversely of the assembly 32, the thickness of the bracelet is kept within narrow limits and the same may have a slender appearance, while longitudinal expansion of the link assembly 32 in consequence of its compression enhances its pleasant appearance of obliquely interwoven, continuous bands 50, 52, 54 and 56, for instance (Fig. 1). Compression of the link assembly 32 also efiects a positive interlock between the intermeshed convolutions 26 of adjacent links 22. The interlock between the intermeshed convolutions 26 of adjacent links 22 is two-fold. Thus, the intermeshed convolutions 26 are, in consequence of the compression of the links 22 of the assembly 32, deformed at their intersections in a manner approximately like that shown at 58 in Fig. 9. The portions of the intermeshed convolutions thus deformed are firmly interlocked, and the interlock thus obtained between adjacent links 22 is in itself sufiicient effectively to resist separation of these links. In addition, the intermeshed convolutions 26 of adjacent links 22 of the assembly 32 are, also in consequence of the compression of the latter, projected into each other as shown at 60 in Fig. 8, to the extent that they resist separation of the links.

The described interlock between the adjacent links ofthe bracelet, while being a limited interlock in the sense that the adjacent links 22 of the bracelet are permitted to pivot slightly about axes parallel to their longitudinal axes, nevertheless lends such considerable tensile strength to the bracelet that it will not come apart even on the application of force which is considerably greater than that to which the bracelet is subjected in ordinary usage. The adjacent links 22 of the bracelet are even further, and quite considerably, reenforced against separation from each other by the interlinked or intercurled end convolutions 26'-of said links (Figs. 6 and '7) As shown in Fig. 3, the links 22 from which the bracelet is fabricated are oval, or generally oblong, rather than round in shape, securing the advantage that more nearly cylindrical openings 30 of maximum cross-sectional area between the intermeshed convolutions 26 of adjacent links 22 permit the ready assembly of said links 22 with strong temporary pins 28 of relatively large diameter. The generally oblong shape of the 4 links 22 secured the further, important advantage that the bracelet will be more slender, and will enhance its appearance of obliquely interwoven, continuous bands rather than have the unsightly appearance of connected spiral elements. Hence, despite its very considerable tensile strength, the bracelet may be slender in appearance, particularly since the oblong links 22 may be made of relatively heavy stock without appearing unduly,

bulky in the bracelet.

The links 22 from which the bracelet is fabricated are extremely simple and inexpensive to make. Furthermore, the described steps of assembling the links 22 and forming them into the bracelet 20 constitute a method which lends itself to highly efiicient mass production of the bracelet at very low cost.

While the abovedescribed method of making the bracelet contemplates the use of temporary pins 28, it is to be understood that these pins may be dispensed with altogether. So long as the intermeshed elements 22 (Figs. 2 and 3) are confined between the retainer platens 40, they will remain in their intermeshed relation without the aid of the pins 28, and will be axially compressed by the rams 36 (Fig. 2) into the form of the bracelet shown in Fig. 1. The elements 22 may, of course, be intermeshed as shown in Fig. 2, and placed between the retainer platens 40, without the aid of the temporary pins 28, as will be readily understood.

While we have shown and described several forms of our invention, it will be understood that our invention may be embodied otherwise than as herein illustrated or described and that various changes may be made in the details of construction and in the arrangement of parts without departing from the invention as defined by the patent claims.

Having thus described our invention, what we claim and desire to secure by Letters Patent is:

1. A bracelet band, comprising a series of alternate, oppositely directed spiral elements arranged side by side with the convolutions of adjacent elements in meshed relation, the intermeshed convolutions of adjacent elements being at each of their intersections mutually deformed into mutual interlocked relation to prevent substantial relative movement between said adjacent elements, said interlock between the intermeshed convolutions of adjacent elements solely holding the latter against separation.

2. A flexible bracelet band, comprising an assembly of alternate, oppositely directed spiral elements arranged side-by-side with the convolutions of adjacent elements in meshed relation, the intermeshed convolutions of adjacent elements being at each of their intersections mutually deformed into mutual limited interlocked relation to prevent substantial relative movement between said adjacent elements, other than restricted relative pivotal movement therebetween about axes parallel to their longitudinal axes, said interlock between the intermeshed convolutions of adjacent elements solely holding the latter against separation.

3. A flexible bracelet band as set forth in claim 2, in which each spiral element is formed of substantially fiat band stock disposed widthwise substantially parallel to the longitudinal axis of the element.

4. A flexible bracelet band as set forth in claim 2, in which the elements have generally oblong convolutions and are disposed in the band so that they extend with the longer dimensions of their convolutions longitudinally of the band.

5. A flexible bracelet band as set forth in claim 2, in which each spiral element is formed of substantially fiat band stock disposed wldthwise substantially parallel to the longitudinal axis of said element, and said elements have generally oblong convolutions and are disposed in the assembly so that they extend with the longer dimensions of their convolutions longitudinally of the assembly.

6. A flexible bracelet band, comprising a series of alternate, oppositely directed spiral elements arranged side by side with the convolutions of adjacent elements in meshed relation, the adjacent end convolutions of adjacent elements being intercurled and the intermeshed convolutions of adjacent elements being at each of their intersections mutually deformed into mufal limited interlocked relation toprevent substantial rela- REFERENCES CITED The following references are of record in the file of this patent:
