NECKLACE Filed Oct. 11, 1929 wind Er Patented Apr. 7, 1931 DETE HEINRICH WANDER, F GABLONZ-ON -THE-NEISSE, CZECHOSLOVAKIA NECKLACE Application filed October 11, 1929, Serial No. 399,039, and in Czechoslovakia October 15, 1928.

Necklaces composed of separate cylindrical elements having their peripheral surfaces set with stones have hitherto been made from solid metal discs, in which the apertures for the reception of the stones have been produced by boring or else by turning suitable rings. The stones were then secured in the first case by cementing them in and in the second case by flanging over the margins of the disc. 7

The necklace elements or beads thus produced were heavy. In consequence of the great waste of material and the tedious and complicated work they were also expensive,

and the stones were not very securely set.

Necklace elements made according to the present invention are on the contrary light,

and therefore cheaper, and make ordinary stone setting quite reliable. The manufacture is exceedingly simple.

The invention consists in producing two thin suitably embossed or stamped metal discs, with or without flanged edges, which, when assembled, form round grooves for the stones to be inserted or else'recesses shaped to fit the stones, and which, after the insertion of the stones, are riveted or soldered together or connected by means of a link, key, cotter or the like.

The invention is illustrated by way of example in the accompanying drawings, in which,-

Figure 1 illustrates a necklace element in the finished condition, and

Figure 2 a section through such an element,

Figure 3 shows the two metal plates before being assembled, and in a different constructional form,

Figure 4 is a similar view of another constructional form,

V Figure 5 is a sectional view of a constructional form in which separate cover plates are employed, and

' Figure 6 shows in section the combination of a plurality of necklace elements by means of a link or pin to form a chain unit. 7

Each necklace element comprises at least two thin embossed metal plates 1 and 2, with may differ in form and may be of. various or without flanged edges. The two plates.

profiles according to the effect contemplated.

Each two metal plates fit on to one another. They have in the centre the necessary holes 3 and 4 for threading them on a string or for link pins for joining them together. .Furthermore the metal plates 1 and 2 may comprise indentations adapted to fit into one another, which serve to prevent relative rotation of the discs 1 and 2. The margins 6 and 7 are formed with embossed cavities or grooves corresponding to the stones to be inserted. One of the two metal plates receives in all cases the form of the stones 10, embossed at a suitable distance apart round the margin. The second metal disc may also receive the same form in a corresponding position. Usually it is sufiicient to form in the second metal plate a hollow embossed groove 6. The flanging of the edges of the two metal plates 1 and 2 may if preferred be omitted. In this case the edges which. serve for the setting of the stones are replaced by simple cover plates 11 and 12 with flanged edges, as shown in Fig. 5. Between the margins thus embossed, or the setting produced in either I of the aforementioned ways, the stones 10 are then secured. I

The insertion of the stones is eflected in the following manner One metal plate embossed to correspond to the shapes of the stones is laid down and the stones are deposited in the recesses thereof.

The second and corresponding disc is then placed thereon in such a way that the indentations 5 in the two plates register with one another. The closing is then efiected' by means of an eye 8 and a pair of spring tweezers. The eye 8 is passed through the holes 3 and 4. It may if preferred form part of one of the two metal plates, preferably the lower one, provided with the shaped hollows of the stones, as shown in Fig. 4. The joining of the metal plates may be efiected by soldering, for which purpose the plates 1 and 2 are provided with holes 9 besides the corresponding indentations 5. It is also possible to connect the plates by means of a link pin 13, as shown in Figure 6. In the case of button-like perforations of the disc, the necklace elements may also be employed for hand work. It

may be just mentioned in connection there with that in consequence of the employment of embossed metal plates the nature of the setting admits of being varied according to taste without making the article more expensive, which was hitherto not possible. Furthermore it is possible to combine in various ways'elements of different sizes and thereby use the element in a great variety of ways. lVhat I claim is 1. A necklace element, comprising two embossed metal plates secured together, the form of the plates being such that when they are secured together they jointly form a series of peripheral cavities each adapted to receive one stone.

2. A necklace element, comprising two embossed metal plates each formed with a hole in the centre, and a hollow cylindrical eye adapted to extend from the central hole in one plate through the central hole in the other plate tojoin the plates together, the form of the plates being such that when they are secured together they jointly form a series of peripheral cavities each adapted to receive one stone.

3. A necklace element, comprising two embossed metal plates soldered together, the form of the plates being such that when they are secured together they jointly form a series of peripheral cavities each adapted to receive one stone.

4. A necklace element, comprising two embossed metal plates secured together, of which one has around its circumference a series of depressions, the other having an embossed groove for the purpose of forming a series of peripheral cavities each adapted to receive one stone.

5. A multiple necklace element, comprising an even number of metal plates secured together in pairs, each formed with a hole in the center, the form of the plates being such that when they are secured together they jointly form a series of preipheral cavities each adapted to receive one stone, a link pin passing through the centers of all the metal plates to join the several pairs of plates into a unit, and rings formed at the end of the link pin to enable the multiple elements to be linked together to form a chain.

In testimony whereof I have signed my name to this specification.

HEINRICH VVANDER.
