f BRACELET-LINK.

To u!! iff/0m 'if 'may concern? l Be it known that I, CHARLES J. CALLA- at Attleboro, in the cotintyof Bristol and State ot' Massaclins'etts, have -invented certain nen-"and useful .lmprovementsin Bracelet-l.inks.'of which the following is a specification.

)lyiinvifntion relates toexpansion bracelets ot the slidable link type wherein middle links intercngzile in slidable relation with outer or initie links. ln this type of bracelet the ends ot' the outer or guide links are composed of connecting posts riveted in position, or consist ot' don'nivardliY directed ears having" socket connections near their Vadjacent, connu-:iingends, which have for that reason been reduit-ed to be overlapped.

The objects ot' the present invention are essentially to avoid the resultant spreading,r oi' the bodies or outer-guide links diie to the nnfaslenin"r oi' the posts or connected lugs and therein i'o increase the strength of the bracelet band; and to eil'ect. this end in a fonstru `-tion which is inexpensive and easy to manufacture.

.\ further object is to increase the smooth-.j

nessl ot the slidingr action of the structure.

'l`o the above ends essentially my invention consists in such parts and such combinations ot' parts as fall within the scope of,

ln the accoiupan'ving: drawings which i'orni a part of this specification: Figures l and 2 are planand side elevations respectively of a bracelet constructed in accord' ance with in present invention.

or guide links B. In detail each inner link consists of a flattened curved oblong loop havingbroadside walls a, and upon one end of the linkoppositely disposed lateral posts a2 located at the abutting ends a3 of the stock from which the link is Originally cnt. and bent, best shown in Figs. 8 and 9. Each link memberll is cutfrom a single blank r and cupped iip formingr two curved oblong s guide plates or shells Y) iinited by an intermediate retracted neck portion Zi and having end ears or lugs b2, the latter being provided'A with perforations 3. This blank B is next bent. bringingthe shells int-o snbstantial parallelism. with the retracted portion tormin;r an integral end post-b', and the lugs b2 are inwardly bent towardeach other so thatwhen the member B is coinplete the lugs b2 have their adjacent edges in Contact with each other and form subs'tantialli7 an end post,` as clearljy7 shown in Fie: 13. l =\Eacli inner link A slidablvengages tivo adjacent ,timide links. B, intermediate the tvvo ,oppositeshells 7) of each link B, and the 'projections a2 extend Within the sidesof the shells which form guides for the. links A. In each link is a helical spring C having. one end pressingr againstJ a -post o', and its opposite end pressing against the end of the link A i'ipon ii-"liichthe projection cl2 occurs sothat the bracelet is held in retracted positionthercbv. as sliowii in Fitz. 3. The r elati\'e. positions of the described parts ivlien the bracelet is partiallyI expanded is shoivn in Fin. 4. Tt is vitallv essential that the lugs 7); be so iirnil)T iinitcd as to avoid 90 an)r possibilit)Y ot their Vseparation :ind the consequent distention of the shells 7 While Athe bracelet is in iise. or is subjected to the clem-hinglr member D. shown in fdetail in Fien l0, which comprises a fiat oblong' rectangular body portionf with oppositelv dis- [3. placed .with .its face abutting against the' inner faces of the liiL'sv 7)?. and Vthen the iin- ,aersf/ are bentat right. angles to the body d and passed through the openings 713 in the edges in Contact with each other, so that the lugs are clamped or clenched together with their abutting edges in tight and immovable Contact with 'each other.

A. pair of bracelet links each formed with parallel shells, an end post integral with the shells at one end and lugs integral' with the opposite ends of the shells and provided with perfomtions, a clenchng member com# prising n body resting against the sides of said lugs and clamping fingers upon the body extending through the perforations and bearing against the sides of the lugs opposite the body, and an inner link in one inte ral element embracingvthe post of one of s id links :ind slidable between the shells.

In testimony whereof I have a'flxed my 2 signature in presence of two witnesses.
