Description
SPECIFICATION
An article of jewellery
This invention relates to an article of jewellery.
This invention also relates to a method of producing the article of jewellery.
Articles of jewellery are known in which at least one precious or semi-precious stone is mounted on a chain which is made of a noble metal. In one such known article of jewellery, the chain is formed of links and the links are formed as castings with integral rods for securing the precious or semiprecious stones in position on the chain. The casting of the links is complicated and time consuming and this can substantially affect the cost of the article of jewellery.
It is an aim of the present invention to obviate or reduce the above mentioned problem.
Accordingly, this invention provides an article of jewellery comprising at least one precious or semi-precious stone which is mounted on a chain which is made of a noble metals the chain being a box section chain having flat sided links which interconnect with one another, the flat opposing sides of alternate links forming sides of the chain, and each flat opposing side of at least one of the alternate links being provided with at least one rod member which is secured to its flat opposing side and which acts to secure the precious or semi-precious stone in position on the chain.
The box section chain without the rod members can be purchased as a proprietory item and it is sometimes also known as Venetian chain. The chain is particularly useful in forming the article of jewellery since it is able to bend in several different directions and thus is able to hang nicely or mould about a person.
Usually, a plurality of the precious or semiprecious stones will be mounted on the chain.
In this case, there will usually be one of the precious or semi-precious stones in each of a series of the alternate links.
The flat opposing sides of the or each alternate link are each preferably provided with two of the rod members. In this case, it will be apparent that the or each alternate link is provided with a total of four rod members which gives a particularly positive securing action, especially for rounded precious or semiprecious stones.
Usually, the rod members will be of circular cross section. Rod members of other cross sectional shapes may however be employed.
The rod members may be secured in position by brazing, welding or soldering.
The article of jewellery may be in the form of a bracelet, a necklace, an earing or a ring.
Other articles of jewellery may be produced as desired.
The noble metal may be gold. The gold may be yellow or white gold and the gold may be 9, 18 or 22 carat. The noble metal may alternatively be platinum or silver.
The precious stone may be a diamond or a saphire. Other types of precious or semi-precious stones may be employed.
where the article of jewellery is provided with a plurality of the precious or semi-precious stones, then the stones may be of the same type or of different types in combination.
The links of the chain may be square, rectangular or octagonal in plan view.
The links may be plain or diamond cut.
The present invention also provides a method of producing the article of jewellery, which method comprises passing the said at least one rod member through a location aperture in a top portion of a jig, placing the chain on a first side of the jig, securing the rod member to one flat side of a link of the chain, cutting the rod member to length, placing the chain on a second side of the jig with the opposing flat side of the link exposed, securing the said at least one rod member to the opposing flat side of the link, and cutting the rod member to length, the second side of the jig being lower than the first side of the jig to allow for the thickness of the rod which is first to be secured in position on the link.
Usually, there will be a pair of location apertures for each rod member, each aperture of the pair are being effective to secure the rod member on one side of the jig.
Preferably, there are a series of pairs of location apertures for receiving a series of the rod members.
The jig may be made of mild steel or any other desired suitable material.
When the rod members are secured by braising welding or soldering, then the heat involved in the brazing, welding or soldering is usually such as to cause the metal to become dark. The darkened metal is usually oxidised metal which can be removed by dipping the article of jewellery in an appropriate chemical bath, for example into a bath of sulphuric acid if the chain is made of gold.
An embodiment of the invention will now be described solely by way of example and with reference to the accompanying drawings in which:
Figure 1 shows part of an article of jewellery in the form of a bracelet;
Figure 2 is a side view of the bracelet shown in Figure 1;
Figure 3 is a top plan view of the bracelet shown in Figure 1;
Figure 4 shows a jig being used in the making of the bracelet shown in Figure 1; and
Figure 5 is an enlarged cross section through the jig shown in Figure 4.
Referring to Figures 1,2 and 3, there is shown an article of jewellery in the form of a bracelet 2. The bracelet 2 has precious stonesir! the form of diamonds 4 mounted on a chain 6, which is made of the noble metal gold. As shown, the chain 8 is a box section chain having flat sided links 8. The links 8 interconnect with one another as shown in
Figure 1. The flat opposing sides of alternate links 8 from the sides of the chain 6.
As shown in Figures 1,2 and 3 each flat opposing side 10 is provided with two rod members 12 which are of circular cross section and which may be made of the same metal as the links 8 or which may be made of a different metal. The rod members 12 are secured to the flat opposing sides 10 by brazing, welding or soldering and the rod members 12 may be brazed, welded or soldered at one or more spots along their lengths or they may be brazed,welded or soldered along their entire length that runs adjacent the flat opposing sides 10. The rod members 12 act to secure the diamonds 4 in position on the chain 6 and, to this extent, the upper ends of the rod members 12 remote from the links 8 may be bent inwardly about the top of the diamonds 4.
The chain 6 is able to flex in various directions and it is thus comfortable to wear on a person's wrist as the bracelet 2.
Referring now to Figures 4 and 5, there is shown the bracelet 2 in manufacture. The bracelet 2 is made by placing a plurality of rod members 12 through pairs of location apertures 14 in a top portion 18 of a jig 18.
With the rod members 12 in position, the chain 6 may be placed on a first side 20 of the jig 18 so that two rod members 12 can be secured to each flat opposing side 10 on one side of the chain 6. The rod members 12 are secured in position by brazing, welding or soldering as mentioned above. After the brazing, welding or soldering the rod members 12 are cut to the length shown in Figure 1. The chain 6 is then turned over and the chain 6 is placed on a second side 22 of the jig 18 with the opposing flat sides 10 on the other side of the chain 6 exposed. Further pairs of rod members 12 are secured by the brazing, welding or soldering to the exposed flat opposed sides 10 with the chain 6 in position on the second side 22 of the jig 18. As before, the rod members 12 are then cut to the length shown in Figure 1.
It will be seen especially from Figure 5 that the second side 22 of the jig 18 is lower than the first side 20 of the jig 18. This is to allow for the thickness of the rod members 12 as shown in the left hand side of Figure 5.
By having lots of the location apertures 14 and lots of the rod members 12 in position of the location apertures 14, then a long length of one side of the chain 6 can be provided with the rod members 12 before the need to turn the chain 6 over and provide its other side with the rod members 12.
Usually, the jig 18 will be made of mild steel but it can be made of any other desired material. If the rod members 12 and/or the links 8 become blackened during the brazing, welding or soldering operation, then the chain 6 with the rod members 12 attached can be dipped in a bath of sulphuric acid or other appropriate chemical to deoxidise the material causing the blackening.
It is to be appreciated that the embodiment of the invention described above has been given by way of example only and that modifications may be effected. Thus, for example, the article of jewellery could be a necklace, an earing or a ring instead of a bracelet. Also, the links 8 could be rectangular or octagonal in plan view instead of being square in plan view as shown in the drawings. Furthermore, the article of jewellery can be made in any desired noble metal using any desired precious or semi-precious stones.
