摘要:
A method of producing stone-set jewelry includes the step of forming at least one affixation-groove (15) within the stone (10) to be set in the jewelry. A stone to be set with the present method should have an upper and a lower portion which is at least substantially entirely hidden from view when the upper portion of the stone is viewed. In accordance with the present method the affixation-groove (15) should be formed in the lower portion (16) of the stone such that it too is hidden from view when the upper portion of the stone is viewed. The method also includes the deposition of a mounting material within the affixation-groove by applying a conventional casting method. Finally, any excess deposited mounting material can be removed and the stone affixed to the article of jewelry via the mounting material such that the mounting material of a completed article of jewelry is not visible when the stone is viewed from the upper portion thereof. New articles of jewelry formed from the methods of producing jewelry are also disclosed.

The invention in the main relates to items of jewellery, wherein gem stones are set in malleable material such as gold sheets to form lockets and the like. Setting heretofore has been by hand by skilled craftsmen, who can work only in relatively thick material, which increases the cost of the jewellery. In the inventive method, much thinner sheet material is pressed to form a recess for the gem, and projections around the recess. The stone is placed in the recess and the assembly is pressed in a jig, which causes the projections to be deformed and form claws over the stone edges setting it in the sheet. The invention also provides an item of jewellery, and a machine for carrying out the method.

A body (1) is machined in order to form: an axial cavity (5) for the stone or other item, said cavity having an edge (1B) that can be pressed over in order to anchor the stone; a lip (1E) that forms an abutment surface (1F) for resting against the surface of the laminar support (3) around a hole (4) formed in said support; adjacent to said lip (1E), a bearing section (9) that widens out and bears against the edge of said hole (4) in the support; and an elastic projection (11, 11A) that is joined to and extends from said section (9) and that can pass into said hole (4) and then re-expand so as to bear against the edge of said hole.

Disclosed is an improved jewel setting method comprising the steps of: making a hole (3) in an object (1) which is capable of returning to its original shape and size after being deformed; forming overhangs (8) around the top circumference of the hole (3); and press-fitting a jewel into the hole (3) by causing the overhangs (8) to be yieldingly withdrawn, allowing the girdle of the jewel to pass through the space (7) delimited by the surrounding overhangs (8), and then, allowing the overhangs (8) to return to their original positions, thereby catching the bezel of the jewel. Thus, neither hammering nor pressing is required in mounting jewels in objects. Examples of such materials are plastic, ivory, horn, wood and metal.

Le procédé utilise la mise en vibration de la pièce et la détection de perturbations dans les vibrations. L'appareil pour la mise en oeuvre de ce procédé comporte un vibreur (21) équipé d'une pince orientable (22) dans laquelle on fixe la pièce à tester (23). Un accéléromètre (34) fixé au support vibrant (30) de la pince délivre un signal de sortie à un circuit électronique qui en supprime les basses fréquences et qui commande des voyants lumineux indiquant l'acceptation ou le refus de la pièce. On peut modifier l'orientation de la pince pendant le contrôle.

L'invention concerne un procédé de sertissage de pierres précieuses ainsi que bijou obtenu par la mise en oeuvre de ce procédé. Ce procédé est caractérisé en ce que l'on fabrique un élément support métallique (2) à section en forme de U comportant deux bandes latérales (20, 21) séparées par une bande centrale (3) et définissant, entre-elles, une gouttière (6), on perce des trous (5) dans chacune des bandes latérales (20, 21), on met les pierres en place dans la gouttière (6) et on fait passer un fil (7) dans les trous (5) de part et d'autre de la gouttière (6).
摘要:
La présente invention a pour objet des procédés de fabrication mécanisée de bijoux comportant une pluralité de petites pierres jointives enchâssées dans un support en métal précieux. On usine dans un support en métal précieux (1) une pluralité de logements juxtaposés (2) comportant chacun un siège conique. On usine dans chaque siège une gorge (6) et éventuellement une deuxième gorge (7) qui délimitent un support annulaire (8) déformable en flexion, portant un siège annulaire étroit (3a), sur lequel une pierre (11) prend appui, on place une pierre (11) dans chaque logement (2) et on appuie sur les tables (13) de toutes les pierres pour les enfoncer dans leur logement en déformant les sièges (3a). Après quoi on sertit les griffes (10). Une application est la fabrication mécanisée de bijoux comportant des pavages de petites pierres.
