This finvention "relates to a method '0 making a flxibl pracelet chain com rising "1a series oft interconnectedIinksT l1 o'neo'f -th' objects of this invention is to provide a simple, "'praeucar a a"durable; "flexible bracelet chain. Another object is 'to provide a; bracelet chain of the abo've "character" which maybecon's'tructedpf inexpensive 'material with um of' l'abor. Another 'objectf-is to pro} vide ''a" "b acele't'" clfa'i'n' e'f the above character which mayT-beassembled by 'a machine opera; tior'i. -Another'ebjeetis provide a bracelet chain of*tlieabove character which w'illib'e attrac tive and graceful in appearance. Answererject'is to 'providea' method of making a flexible bracelet chainin which the individual parts may be quickly assembled intotl'ie'flnahconstruction ina. minimum numberofyoperations, Otherobjects will be in part obvious and..:ini-part:;pointefi out hereinafter.

' Figure 3 is a fragmentary perspective view, partially exploded to show the first step in connecting a side link to a pair of connector pins;
Figure 4 is a view similar to Figure 3, showing the next step in this assembly operation;
Figure 5 is a cross section of the parts as shown in Figure 4; and
Figure 6 is a cross section similar to Figure 5 but showing the parts after the assembly has been completed.
Similar reference characters refer to similar parts throughout the several views of the drawings.
As best seen in Figures 1 and 2, the bracelet chain comprises a series of oblong connector links, generally indicated at H), arranged in staggered relationship and. held assembled by a series of pairs of cross pins, generally indicated at II. More particularly, the cross pins H are held in fixed pairs because they are secured to the oblong side links, generally indicated at l2.
Thus, a pair of cross pins I l with the side links Zis an enlarged perspective view-"of a .2; IZJL'SEOIIIQdthereto at. opposite ends ccmpr'isesf'a unitary'crossffilink, r' 'g'enerall imitated -a'.t"- connected-to.adjacentfiinks-roi imiiar ciinstr A tio'n by' the"connector" 1inks"I 0T Additionally, there are bands, generally indicatedia c extend; about the pins 1 preach These bands Min chain'but' a'lso *a't *tdmaintai mks-1| 0 in:properly spaced'relationship. be' described'f more funy hereinafter; ther metalii'nserts; generally indicated at t5" in *e h" of saidsi'de "links disposed betv'v'ee the pd as tionsof the adiacent pin's TI.

The pins H are also of standard length and may thus be cut 1automatically, ready for the assembling opera ion.
To assemble the bracelet, the connector links ID, the side links l2 and the bands I4 arelaid out in any suitable holding device so that they will be maintained in staggered relationshipgiifi the position they will assume in the completed, bracelet. With these parts thus held in this position, the pins H may be inserted crosswise to assume the positions they occupy in the com-. pleted bracelet. Next, it is necessary to secure the ends of the pins u to the side links l2.
As best seen in Figure 3, the metal inserts I5 comprise a metal plate I6 with a solder coating I! on one surface thereof. The inserts [5 also have formedalong their opposite edges teeth d, b and 0. These inserts l5 are forced between the end portions of the pins I l into the position shown in Figure 4.
When the inserts come to rest in the desired position as shown in Figure 4, the teeth a and thereof abut against the sides of the pins H, but the center teeth b are bent upwardly to fit against the center portion of the pins H, as will be clear from a consideration of Figure 5. After all of the inserts 15 are in place, the assembled bracelet chain may be heated in any well known manner so that the solder on the coating l1 runs freely about the end portions of the pin. Thus, the solder not only seals the inserts l in position but also runs about between the surfaces of the pins and the inner surfaces of the side links l2. Upon cooling, as seen in Figures 2 and 6, the solder is interposed between the engaging surfaces of the side links l2, the pins 1 I and the inserts l5 to hold these parts rigidly. The completely assembled bracelet chain may finally be coated or plated with any desired metal, for example, a gold plating operation. This plating operation will form a finished surface to cover up all solder connections and the ends of the pins H.
The finished bracelet chain is unusually sturdy in construction and yet may be easily assembled.
In fact, this method of assembly is conducive to the use of machine processes throughout so that the bracelet chain may be manufactured inexpensively. Nevertheless, in spite of the simplicity of its parts and ease of its manufacture, it provides a graceful and pleasing appearance.
It will thus be seen that the various objects hereinabove referred to have been successfully accomplished in a practical manner.
As many possible embodiments may be made of the mechanical features of the above invention and as the art herein described might be varied in various parts, all without departing from the scope of the invention, it is to be understood that all matter hereinbefore set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
, I claim:
1. The herein described art of forming a link ina bracelet chain comprising fitting a pair of oblong links over the opposite ends of a pair of pins so that the ends of the pins lie adjacent the ends of the links with space between the pins, forcing metal inserts having a coating of solder thereon between said pins at the opposite 4 ends thereof and heating said links to form a solder connection between the parts.
2. The herein described art of forming a bracelet chain, comprising, connecting a series of pairs of pins by a plurality of oblong links, fitting a pair of oblong links over the opposite ends of each pair of pins so that the ends of the pins lie adjacent the ends of the links with space between the pins, forcing metal inserts having a coating of solder thereon between said pins at the opposite ends thereof and heating said links to form a solder connection between the parts.
3. The herein described art of forming a bracelet chain, comprising, connecting a series of pairsof pins by a plurality of oblong links arranged in a longitudinally staggered relationship, fitting a pair of oblong links over the opposite ends of each pair of pins so that the ends of the pins lie adjacent the ends of the links with space between the pins, forcing metal inserts having a coating of solder thereon between said pins at the opposite ends thereof and heating'said links to form a solder connection between the parts.
4. The herein described art of forming a link for use in a bracelet chain, which includes, connecting the ends of two pins to the sides of an oblong link by forcing between said pins a metal insert having a solder coating and a plurality of teeth at its opposite ends adjacent said pins so that the side teeth rest against each pin and the middle teeth are bent at an angle thereto, and heating said insert so that the solder coating flows into the space between said pins and said middle teeth. 7
