Definitions

  • the present invention relates to a method of fixing precious stones to a frame, which fixing is carried out using individual pieces, constituted by a head and by a rod, said head having a frustoconical lower part produced so as to bear on the bevel of the table of the stone or stones to be fixed.
  • the present invention relates to an industrial method of fixing precious stones on a frame making it possible to overcome the difficulties due to the use of known fixing techniques.
  • the method according to the present invention is characterized in that said rod being provided with at least one protuberance which, cooperating with the corresponding hole made in the frame, causes sufficient friction to cause the jamming of each individual piece put in place.
  • the individual parts which can be used according to the invention therefore comprise a rod and a head.
  • the rod is intended to enter a hole in the frame so as to secure said part with the frame.
  • essentially the wedging of said rod will be used inside the hole made in the frame.
  • a frame should preferably be used before a hardness of 50 to 60 vickers, a rivet of 130 to 140 vickers and to ensure that the diameter of the part of the rod which comes into contact with the internal surface of the hole is approximately 0.02 mm greater than the diameter of said hole.
  • protrusion on the rod of the individual parts is a metal portion projecting from the cylindrical surface forming the rod.
  • This protuberance can be formed of several individual elements (pins) or of a collar or preferably a frustoconical collar whose ends are very fine (cf. figure). There may be one or more similar or different growths on the same stem.
  • the heads of the individual parts which can be used according to the invention are intended, by their lower face, to press at a point (or along a small area) on the upper face of the edge of a stone. It therefore suffices that this head has sufficient dimensions in width (beyond the rod) to rest on the stone (s). It will be noted that in a particular embodiment of the invention said head can be formed, on the spot, by deformation of the end of the rod which comes out of the hole made in the frame.
  • the heads can have very different circular, ellipsoidal, triangular, star, etc. shapes.
  • the present invention can be used for fixing precious stones on any frame but it is particularly advantageous in the case of a metal or precious metal alloy frame.
  • the preparation of the frame for implementing the invention is particularly simple; it will suffice on the one hand, to make in this frame holes or cells of cylindrical shape capable of receiving the stones and then on the other hand, to drill holes, suitably placed, intended to receive the rods of the individual pieces usable. Note in particular that if the holes or cells intended to receive the stones must have diameters adapted to said parts, the precision of the machining of these holes is much less important than in the case of fixing the stones by other industrialized systems.
