I 'lh1s lnvention relates t'olconstruction for wrist watch chains and the like, andf'with regard" to certain more specific features" to precious metals;

construction for such devices employing Oneof the objects of the invention is to" provide aconstruction of the above nature.

practical and efiicient andcapable of meeting the requirements of use in a highly satisfactory manner. Another object is to provide a construction'of the above nature of a strong and durable characteiz' Another object is to provide a construction adapted, at alltimes, to present a neat and attractive appearance. Another object is to provide such a construction wherein precious metals employed are most economically and advantageously" utilized. Another object of this invention is to provide a wrist chain in which the expansion thereof; necessltated by the attachment of the chain tothe wrist or by its self-adjustment to the wrist, may be achieved without destroying its continuity of design. Other objects willbe in part obvious or in part pointed out hereinafter.

The invention accordingly consists'in the features ,of construction, combinations of elements, and arrangements of parts, all as will be illustratively described herein, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawing in which is shown one of various possible embodiments Figure 5 is a vertical longitudinal section.

Figure 6 is a transverse section taken substantially along the l1ne6-6 of'Figure 5.

Figure *10 isa plan view of Figure 9:

the drawing.

Referring-"now to the"drawing"in'detail, in'Figure l there'is'shown,'somewliat dia grammatically, aplan view ofthe end por lar partsthroughout 'the'several .views "of' tion of a-"chain adaptedfor use in connection witha wrist watch or the like. .Theh chain preferably "comprises a plurality of blocksor bars'indicatedgenerally'at 10 and joined together as will be'later described to forma flexible chain. These'blocks or bars arepreferablyfof similar design and shape and when thus'joined together provide a continuity of design for the chain. At the end of thechainis provided an attaching so device indicated generallyat' 11 for connection with the" wristwatch. 7

Considering now' more particularly the construction of the bars 10 of the chain, as best'fshown'in Figure "5,they are'provided '85 with upstanding sidewalls or flanges "12 so that when resting upon'the wrist their'external appearance is substantially that of a solid member. Also they are connected" I closely together, their end surfa-cesf'abutting. This connectio'n is 5 preferably formed by means of "links such as 13, over "Which are bent end' flanges 14 of the bars." The bars of the chain being-connected together in this 7 manner, no gapsv appear therebetween so that the"exterior appearance of the chain is substantially solid and uniform, regularly marked off by the lines appearing between adjacent bars.

The attaching" device indicated at 11 in Figure 1 has" a hooked portion 15 by means of-which" connection is made with the wrist watch. This hooked portion 15 is formed upona -member 16 which is'provided with upstanding side Walls or flanges 17. A" plate member 18 is connected with these sidewalls 17 'inamann'er to'be later described and thus spaced from the part 16 formstherewithjand thesidewalls 17, a hollow chamber 01* 'passagewithin the attaching "device;

Similar reference characters refer tosiini- 65" At the end of the chain formed by the bars 10 is a longer bar 19 which extends into this chamber or hollow portion of the attaching device. This longer bar 19 is, in construction, similar to the bars 10, being connected to the adjoining bar 10 in the same manner in which the bars 10 are connected to each other and at its inner end within the hollow portion of the attaching device is flanged as at 20. The rear end of the plate 18 is provided with a flange 21 and between this flange and the flange 20 is interposed a compression spring 22. The bar 19 is slidable longitudinally within the hollow portion of the attaching device and the spring 22 thus forms a yielding connection therebetween urging the bar 19 inwardly. By pulling the bar 19 outwardly against the action of the spring 22, it is seen that the chain is lengthened or extended longitudinally and that under the urge of the spring 22 the chain tends to contract to its normal length. Thus in the lengthening or shortening of the chain the bar 19 simply moves outwardly or inwardly at the rear end of the attaching device. In this manner since the bar 19 thus telescopes within the attaching device, no gaps appear in the chain when it is extended. Preferably the outer surface of the longer bar 19 is marked off to resemble in appearance a plurality of adjoining bars '10. In Figure 2 the chain is shown in extended position with the spring 22 compressed and it is seen that this marking off of the surface of the bar 19 preserves the continuity of design formed in the chain by lines between adjoining bars 10. Thisis highly advantageous since the chain has substantially the same exterior appearance in extended position as in normal position. The spring 22 is preferably made'oval in cross section to best conform to the rectangular shape of the hollow portion of the attaching device in which it rests.

The forward end of the plate member 18 is provided witha pair of inwardly curved lugs 23 which are best shown in Figures 3 and 5. These lugs 23 pivotally support a member 2-1 which is adapted to swing into and out of position to coact with the hook 15 and serve as a lock therefor. This member 24 is provided with a handle or lever 25 which. when the member 24 is in looking position, is in frictional engagement with the outer surface of the side wall 17 of the attaching device. This frictional-engagement of the lever 25 serves to dependably hold the lock in operative position. As is seen in Figure 5 the lugs 23 supporting the lock 24 serve as a stop to limit the inner movement of the bar 19.

Considering now more particularly the material of which these parts are made, they are preferably made of metal which is filled or plated with another more precious metal,

for example, they may be gold-filled or goldplated. Referring particularly to Figure 6, the member 16 with its side walls 17 described above comprises preferably an inner layer of base metal 16 having the side walls 17 and an outer covering 16 of a precious metal, such as gold. The plate member 18 comprises an inner member 18 of base metal having an outer covering 18 of gold. This plate member 18 rests upon the upper surface of the side walls 17 of base metal of the member 16. The covering 16 of 'gold extends beyond the ends of the flanges or side walls 17, as at 16 and is flanged over the edges of the member 18. The covering of precious metal 18 terminates a short distance from the edges of the member 18 upon which it is formed and the edges of the flanged portion 16 of the covering 16 meets these edges of the covering 18 as at 26. This line of meeting is clearly shown in Fig. 3. In this manner the flanged ends 16 of the precious metal hold the member 18 in place and a complete covering of precious metal is provided. The surface of the member 18 forms the inner surface of the attaching device, that is, the surface which contacts the wrist, and it will be seen that the construction just described prevents any base metal from coming in contact with the skin and further preserves the full thickness of the precious metal covering throughout and makes for most economical utilizatio of the precious metal employed. f

Referring now particularly to Figure 8, the bars 10 with their side walls or flanges 12 preferably comprise an; inner member 10 of base metal having the flanges 12 and an outer covering 10 of precious metal. In forming the bars the base metal portion 10- having flanges or side walls 12 and the flanges 14 is preferably first formed as 7 shown in Figure 8. Thereupon the outer coating 10 of precious metal is applied.

Then a part of the end portions of the flanges 12 is forced downwardly as shown in Figure) leaving a thinner portion 12 of base metal and making the lower portion 12 of the fianges thicker thus forming shoulders 12. Thereupon the thin end portion 12 of base metal, together with the covering of precious metal 1O thereon is flanged or bent over against the shoulder 12.

A cross section of the resulting structure.

is shown in Figure 7 and it is seen that the flanged other portion 10 of precious metal forms the inner surface of the bar, that is the surface which comes in contact with the skin. By forming this portion of the bars as above described the full thickness'of the precious metal to permit exposure of the base metal therebeneath. The inner surfaces of the side walls of the longer bar 19 are formed in a similar manner as shown at 19 in Figure 6. Thus the surfaces of the chain and other parts which contact the wrist are all plated with the precious metal and the base metal which lends the necessary strength to the structure does not come into contact with the skin. The precious metal employed is utilized in a most economical and advantageous manner.

From the foregoing it will be seen that there is herein provided a construction which embodies the features of the invention and attains the objects thereof including-xmany practical and useful advantages. It may here be noted that the terms blocks or bars as employed herein are to be interpreted broadly throughout to include any suitable members adapted to perform the functions described.

As many possible embodiments may be made of the mechanical features of the above invention and as many changes might be made in the embodiment above setforth, all without departing fromthe scope of the invention, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
