Application April 10, 1941, Serial No. 387,818

6 Claims.

The present invention is concerned with linkages and more particularly with chain and ibracelet linkages in costume jewelry.

It is one of the objects of, the present invention to provide a linkage in which the links have a Wide freedom of rotary movement and no translatory movement at all relatively to one another.

It. is also an object to accomplish this result without the use of intermediate, separate comiectors between the links. Another object is to make the links of castings to give the linkage weight and solidity of mass construction, a feature greatly appreciated and sought in costume jewelry; also, to give the construction and form of the links a greater scope of variation as compared with links made of stampings. A further object is to provide a linkage for bracelets which readily accommodates itself to the shape of a womans wrist. Still another object is toprovide a chain the links of. which can not be easily pulled apart and which is so strong that it is practically undestructible. Yet another object is to accomplish all of the above results by a simple construction and an easy assembling operation, at a low costof manufacture and material. An additional object is to provide a linkage which readily lends itself to ornamentation, including surface treatment, such as plating and the like, and jewel setting. Other objects not specifically enumerated above will become apparent from the specification which follows and from the accompanying drawing, in which Figure 1 is a top plan view of a preferred em.- bcdiment of the invention.

Figure 2 is an underside plan view of three of the links of the linkage shown in Figure 1, connected.

Figure 3 is a cross section taken along the line 3-3 of Fig. 2.

Referring to the figures in detail, I is a double bar link of the linkage shown in Figure 1, and 2 a single bar link of the same linkage. Between the bars of the double bar link 2 are crosspins 3 integral therewith. Slots 4 are provided in the single bar links 2. The bars are made of castings of U shaped cross section, i. 'e. they have a base i and flanges 8 perpendicular thereto. From the base 1, a tongue 5, integral therewith, projects at one edge of the slot 4. The tongues extend over the crosspins 3, being preferably bent over them. When so bent, they are designated in the figures by the numeral 5'. It will be noted that the underside of the links is arched to correspond with the shape of a womans wrist. The single bar links are intermediate the bars of the double A bar links.

relatively to one another.

The crosspins 3 are shown as cylindrical for a reason that will be clear from what follows, but they may be of a shape differing from cylindrical. At the ends, each bar is provided with a socket type frame for setting a jewel therein.

The assembly of the links to form the linkage shown in Fig. l, is very simple. All one has to do is to insert the crosspins 3 into the slots 4 and bend the tonguesfi over the crosspins 3. It will be seen that in this manner the walls of the slots 4, together with the bent tongues 5 constitute bearings within which the crosspins 3 are free to rotate when these crosspins are cylindrical in shape, whereby the links 2 and I are free to turn When this freedom of turning is not desired, the crosspins are made of square or other cross section.

It Will be seen that the linkage here shown requires no intermediate, separate connectors between the links and that the links are so strongly connected that they can not be pulled apart short of breaking the links. Being made of castings, the linkage gives a correct impression of massive construction, a feature much sought in costume jewelry which is customarily made up of stampings which give the linkage a flimsy appearance. Besides, castings afford a wider range of forms and construction than stain-pings. The construction and assembly of the present linkage are extraordinarily simple, thus contributing to efficiency and economy. The arched underside of the links is a desirable feature when the linkage is used as a bracelet.

I claim:

1. A linkage composed of alternate double bar links and single bar links intermediate the bars of said double bar links, crosspins between the bars of said double bar links integral therewith,

slots in said single bar links for receiving said crosspins, and tongues on said single bar links on the inward side of said crosspins bent over them and forming, together with the walls of said slots, bearings within which said crosspins are free to rotate, thereby allowing said single bar and double bar links to freely turn relatively to one another.

2. A linkage composed of alternate double bar links and single bar links intermediate the bars of said double bar links, said bars having a base and flanges perpendicular thereto forming a U in cross section, crosspins between the bars of said double bar links integral therewith, slots in the flanges of said single bar links for receiving said crosspins, and tongues on said single bar links to freely turn relatively to one another.

3. A bracelet composed of alternate double bar links and single bar links intermediate the bars of said double bar links, said bars being'arched on the underside to conform with the shape of a womans wrist, crosspins between the bars of said double bar links integral therewith, slots in said single bar links for receiving said crosspins, and tongues on said single bar links on the inwardside of said crosspins extending over them and forming, together with the walls-of sa'idj slots, 4'

bearings within which said crosspins are free to rotate, thereby allowing said single bar and I double bar links to freely turn relatively to one another.

, 4. A linkage composed of alternate double bar links and single bar links intermediate the bars of said double bar links, said bars being made of castings having a base and flanges perpendicular thereto forming a U in cross section, frames at the ends of said bars for setting jewels therein, crosspins between the bars of said double bar links integral therewith, slots in said flanges of the single bar links for receiving said crosspins, and tongues on said single bar links on the inward side of said crosspins extending over them intermediate said flanges and forming, together with the walls of said slots, bearings within which said crosspins are free to rotate, thereby allowing said single bar and double bar links to freely turn relatively to one another.

5. A bracelet composed of alternate double bar links and single bar links intermediate the bars or" said double bar links, said bars being made of castings and having a base and flanges perpendicular thereto forming a U in cross section, frames at the ends of said bars for setting jewels therein, said links being arched on the underside to generally conform to the shape of a womans wrist, crosspins between the bars of said double bar links, slots in the flanges of said single bar castings for receiving said crosspins, and tongues on said single bar castings on the inward side of said crosspins intermediate said flanges extending over said crosspins and forming, together with the walls of said slots, bearings within which said crosspins are free to rotate, thereby allowing said single and double bar links to freely turn relatively to one another.

6. The method of forming a linkage composed of alternate double bar links and single bar links intermediate the bars of said double bar links, which consists in integrally connecting the bars of said double bar links by orosspins, providing slot in said single bar links, setting said crosspins into said slots, providing said single bar links with tongues on the inward side of said crosspins and bending said tongues over said crosspins.
