This invention relates to certain new v"and useful improvements in expansible bracelets, and the primary object thereof is to provide a' bracelet wherein the links can beeasily and quickly assembled, orfremoved, or applied in order to shorten or lengthen the tured without the use. of solder. Y

The invention stillmfurt'her aims to provide a bracelet wherein the links are adapt-` able for construction from perforate aswell Still further, the invention aims to provide a bracelet where in the links involve a minimum of partsthat are compactly as- In the drawings Fig."1 is a bottom plan view, partly b roken away and in section of several of the Y, and 25 links; y n

Fig. 2 is a ,section on line 2 2 Vof Fig. 1

Figs. 3 and 4 are sections on lines 3--3 and 4-4 respectively ofrFig. 2;

5 is a detail perspective View of one of the boxesand Fig.4 6 is a like view of one of the connectors. Y VIn proceeding' in accordance with the presl i ent invention but three parts are employed,

' `formed of plates which have a down-turnedv -namely'a box 1 a connector 2 and a coil spring 3. Asshown in Fig. 5 ofthe drawings each box Vhas a bottom 4,v endA walls 5, oneof which has ears 10, and sidewalls 6, the whole being made of a single piece of metal with sides and ends bent into the form shown. The side Vedges of the sides 6 arel turned inwardly to form flanges 7V which latter arev disposed above the free upper edges of the ends 5; The connectors 2 are flange 8 at one end, and the sides of the body of the plate at the oppositeend 1ll are formed withoppositely disposed notches 9. In assembly the connector plates 2 are engagedbeneath the.V flanges 7' and the upper free side edges of the'. one of the ends 5 the coil spring 3 being engaged between the bottoms4 of the boxes and the plates 2, and at vone end abut the flanges 8 of the plates 2 and at their opposite ends abut the 'adjacent ends of the boxes. It isV understoodv of course that the sides ofthe boxes are in this bottom of the boxes occur -at of the top ofthe bracelet. v I

To connect the links one to thefotherit is merely necessary to move the connectors 2 of the adjacent link against the tension of vthe .i Thus eachV link consists of but thre-e parts j that are assembledjwithout the use of solder. f
