I "BRACELET.

J To all 'whomit may concern":

iBeit linownth'at I, Am: HADLEY, a subject 'oflt'he King of England,'and resident ofthe eity'of Providence, in'the county of Prayililenc'e and State of 'Rhode Island, have '1n-- ven'ted 'certainnew. and useful Improvements -in Bracelets, of which the following This invention relates to bracelets and has f0'r its object to provide a novehform of extendible bracelet in which the elements are 'all connected together by the folding of one portion of the stock over that of another where they. are joined without the use of solder, thereby providing a Construction which is'inexpensive to produce and which is strong and durable in construction.

-A 'further object of the invention is to so c'on struct the guide link that its two trough shaped members are formed separate and independentof each other and are provided "with extendingportions at eithe'nend which are adapted to be permanently connected to- 'gether by the folding of the stock to position andiretain the side members parallel in 'spaoed'relation. It is found in practice that by the construction of these members separately they may be formed automatically and very rapidly in a power press all being formed exactly alike by the same set of dies and when one of the 'two is reversed end for end and bothare joined together the edges of the opposite members are positioned and held absolutely parallel so that one cannot get out of line with the other, whereby the slide link will work perfectly between them and will not bind in sliding.

With 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 1- is an edge-view of an expandible bracelet of my improved construction. Fig. 2- is a perspective view of one of the guide links with its side members joined together. Fig.

3- is the shape of a blank as cut from sheet .0 stock from which one side of the guide link is formed. Fig. 4.- is a perspective view showing the next operation in which this member is struck up into a trough shape with the extensions drawn up into positionto engage those of the opposite member. Fig. 5- is a perspective'view' showing the V Specification of Letters Patent. -Paten t ed May 25, 1915. "'A' iiatibn aie 'iibveniber 5,1914. Serial 110,870,513. ,"eppositemembers as turned end forend and ready to be set in position to have the wings of one extension folded about the neck portion ofthe'adjacent extension on the opposite members. Fig. 6 is an enlarged-sectional end view showing the wings of one extension folded about the neck portion of the opposite extension for tying the ends of the opposite members together. Fig. 7 is a sectional side elevation showing the. off-setting, of the necked extension inwardly so as to receive the opposite corresponding extension. Fig. 8- is a perspective view of the slide link. Fig. 9 is a perspective .view of the clamp for locking the ends of a slide link together. Fig. 10 is a perspec tive view showing a portion of the slide link with its ends locked together by the clamp shown in Fig. 9. Fig. 11- is a sectional side elevation showing the guide links and slide links connected together and under tension of its spring to hold the same in contracted position.

Referring to the drawings 15 designates one of the guidelinks which is formed by first being cutfrom sheet stock'into the form illustrated in Fig. 3 having a necked extension 16 at one'end and winged extension 17 at the opposite end. The next operation is 'to strike these blanks and draw them up into a trough shape as illustrated in Fig. 4 with the extensions 16 and 17 standing substantially at right angles 'to the plane of the same. It is found very advantageous in practical construction of bracelet-links of this character, to form the two sides or trough shaped members of the guide link separately or in separate pieces and exactly "alike, which may be done by the same die.

By this construction it will be seen that these members may beturned out very rapidly in an automatically operated power press at.

the minimum expense, and when they are joined together one is turned end for. end,

so that the wings 18 on the extension 17 will fit over the necked portion 19 of the finger 16. This finger 16 is off-set inwardly, see Fig. 7, so that the winged extension will fit down over the necked extension when these two members are positioned one upon the other. The wings 18 are simply folded around the neck portion 19 and the two members are positively and most accurately connected together so that their opposite edges 20 and 21 are absolutely in line with between them.

the slide link rigidly binding these ends together.

A feature of importance in the practical and successful operation of my improved braceletis that by connecting the two sides of the guide link by bending of the parts about each other,it is found that there is a certainslight looseness left between the sides of the link which permits the parts to yield and give slightly and'allow the slide link to move back and forth freely therein without bending which is not the case where either one or both of the ends are held tight.

In assembling the members of the guide link, the adjacent fingers at each end are connected together by folding their opposite extensions about each other. The slide link 22 and the spring 26 are then positioned between the oppos'ite sides of the guide link, and the opposite ends of the latter are then connected together. ,By this construction the whole bracelet is built up and the parts operatively connected without the useof solder.

. I claim:

I 1. In abracelet, a guide linkformed of two separate, oppositely disposed spaced apart trough-shaped members, each end of each member being provided with an integral extension, the extensions of each memgral extension, an extension on each member beingofi'set inwardly from the plane of its complemental extension, the extensions of each member being interlocked with op- I posite extensions of the other member.

3. In a bracelet, a guide link comprising two separate oppositely disposed spaced apart trough-shaped members, each end of each member having an integral extension and oneof said extensions being ofiset'in-' wardly from the plane of its complemental extension and said extensions being formed to be connected one with theother to join the ends of said members permanently and rigidly together, a link slidably mounted 'in' thespacebetween said guide link members,

I said extension members also serving to guide said slide link, and a spring for normall retaining said slide link in contracted pos1 tion.

posed trough-shaped members, each end of each member being provided with an integral extension, one extension on each member being offset, theother extension being provided with ears, the offset extension of each member being engaged by the ears :of the other extension of the opposite member. 7 In testimony whereof I afiix my signature in presence of two witnesses.
