Definitions

  • This invention relates to a method of manufacturing bezels for setting precious stones.
  • Various methods have already been proposed for manufacturing bezels constituting supports adapted to receive precious stones or gems secured by setting.
  • the initial material is a solid rod or bar shaped by die-stamping and subsequently machined to form a central bore in the lateral walls of the resulting tube longitudinal notches are formed to constitute the claws for eventually setting the precious stones or gems.
  • Another object of this invention consists in providing an improved method permitting of obtaining a bezel provided with an integral gaged perforated stem adapted to combine a high degree of precision with a particularly rapid setting of precious stones by using only simple means.
  • thismethod of manufacturing bezels for setting precious stones and the like from cylindrical rod stock is characterized in that a blind bore is firstly formed coaxially into the front face of the rod to constitute a recess of relatively large diameteradapted to receive the precious stone, that the dutersurface of the rod is turned so as to form in the rod portion enclosing said recess a hollow head of which the maximum outer diameter is substantially equal to the rod diameter, and a solid stem adjoining said head but of a diameter smaller than the rod diameter, whereafter longitudinal open notches are cut by milling in the lateral wall of said hollow head which open into said front face of the head and form therebetween claws to be used subsequently for setting the precious stone, said stem of minor diameter being then drilled coaxially and severed by cutting from the remaining portion of the rod.
  • the method of this invention is carried out by using for the turning and milling operations milling cutters, twist-bits, carbide and diamond tools capable of combinlng a high degree of precision with a very satisfactory finish.
  • milling cutters twist-bits
  • carbide and diamond tools capable of combinlng a high degree of precision with a very satisfactory finish.
  • very small and therefore cheap diamonds may be used this solution is applicable only because these small diamonds can be cemented to a tool, since the machining operations are performed under oil spray conditions, thus preventing any overheating of the cement.
  • coupled diamonds affording contorted shapes while being extremely simple to cut may also be used. Operating with an ample supply of oil will eliminate completely any loss of gold dust or other precious metal dust.
  • the turning and milling operations are accomplished on a metal rod constantly clamped in a rotary headstock, so that the rod positioning and centres are extremely accurate and the resulting bezel is also characterized by a high degree of precision, thus facilitating the subsequent setting steps performed by using mechanical means.
  • FIG. I is a diagrammatic elevational view of the rod stock before the first axial boring operation
  • FIG. 2 is an axial section showing the rod after this first axial boring operation

  • FIGS. 9 to 14 inclusive are perspective views showing different forms of embodiment of bezels obtained by the method of this invention.
  • FIG. I there is shown diagrammatically the first step of the method of manufacturing bezels which consists in forming an axial concentric bore in a solid metal rod 1 having a diameter a, by means of a twist-bit 2 having a diameter b inferior to said diameter a.
  • the rod 1 is shown in axial section in FIG. 2 after the boring step, the resulting recess 3 having a diameter b and opening into the front or upper face of rod 1, its depth being denoted p
  • this recess 3 may comprise adjacent its outer end a shoulder 4 having a diameter intermediate the values a and b, so that the uppermost portion of the wall of recess 3 will be somewhat thinner.
  • the next step may consist either in milling the claws or turning its outer surface.
  • FIGS. 3a to 3f illustrate diagrammatically the various turning steps required for obtaining different external contours of the bezel.
  • This turning step is directed to produce at the rod end a head of which the maximum outer diameter is substantially equal to the diameter a of rod 1, this head being connected through a narrower stem 6 to the remaining portion of the rod.
  • the head 5 illustrated in FIG. 3a is machined by turning and comprises a cylindrical upper surface 50 having a diameter a, followed by an intermediate tapered or frustoconical portion 5b and then, by another cylindrical portion 50 having a smaller diameter 0 connected to the remaining portion of rod 1 through a stem 6 of reduced diameter the tools implemented for this turning operation are shown diagrammatically at 7.
  • the head 8 of generally cylindro-conical configuration has an upper cylindrical lateral surface 8a of relatively great height having a lower frustoconical extension 8b of reduced height, connected to the stem 6
  • the head 9 comprises two frustoconical sections assembled by their major bases, providing an upper frustoconical surface 9a converging upwards and of relatively great height, connected to the stem 6 through the medium of a smaller frustoconical surface 9b converging downwards and of relatively reduced height.
  • FIG. 3d also illustrates a head 10 of double frustoconical configuration but of reverse structure, i.e. comprising an upper frustoconical surface 10a converging upwards and of relatively reduced height, having a lower extension in the form of another frustoconical surface 10b of relatively substantial height which is connected to the stem 6.
  • the head 11 shown in FIG. 3e comprises an upper cylindrical surface 11a of relatively great height connected through a surface 11b having a curved meridian to the stem 6.
  • FIG. 3f shows a completely cylindrical head having a diameter a and connected directly to the stem 6 of relatively small diameter.
  • FIGS. 4a to 40 A first method of milling said claws is illustrated diagrammatically in FIGS. 4a to 40.
  • the milling operation is accomplished by working on a biconical head 10 obtained by turning as illustrated in FIG. 3d.
  • a milling cutter l3 revolving about a stationary horizontal axis 14 is used.
  • the rod 1 is fed vertically upwards in order to cause the head 10 to engage the milling cutter 13 which, of course, is positioned in a diametral plane of the head.
  • the cutter 13 cuts in the hollow head 10 a pair of diametrally opposed notches 15.
  • the rod 1 is lowered to free same from the cutter l3 and the rod is rotated about its axis through a predetermined angle, whereafter the milling operation is resumed.
  • FIGS. 5a, 5b and 5c illustrate a similar milling operation performed on the head 5 of FIG. 3a by means of a cylindrical cutter 13.
  • notches 15 opening upwards and having a rounded bottom are obtained.
  • the horizontal axis of rotation 14 of the milling cutter 13a extends across the vertical axis of head 5 and each notch 15 is cut by imparting a vertical reciprocating motion to the head 5 in either direction (but alternatively this motion may be imparted to the cutter 3a), to cut each notch 15 separately, whereafter the head is rotated through a suitable angle.
  • These longitudinal notches 15 form therebetween teeth 16 adapted to constitute the claws for retaining the precious stones or gems by setting.
  • FIGS. 6a, 6b and 6c illustrate a milling operation similar to that shown diagrammatically in FIGS. 4a to 4c but performed on a cylindro-conical head 5 by using a cutter 13 cutting only on one-half of the head diameter.
  • the horizontal axis of rotation 14 of this cutter l3 and the vertical axis of the head 5 do not intersect each other in this case and the head 5 is reciprocated along its vertical axis.
  • the cutter 13 cuts only one notch 15, so that an odd number of claw 16 can be obtained.
  • the rod 1 on which a head 5 has been turned is kept in a vertical stationary position while the axis of rotation 14 of cutter 13 is shifted in a horizontal plane while maintaining this axis parallel to itself.
  • the cutter 13 travels in a vertical plane x-y while revolving about its axis, this plane x-y intersecting the outer surface of head 5.
  • the cutter l3 removes from the wall of head 5 the portion extending from the secant plane x-y and the outer lateral surface of the head.
  • a notch 15 of a width varying as a function of the distance from said secant plane x-y to the axis of rod 1 is obtained, and the smaller said distance, the greater said width.
  • FIG. 7d it will be seen that by performing three elementary milling steps in three secant planes such as x-y forming an equilateral triangle, three claws 16 cut in the lateral wall of head 5 are obtained at a relative angular spacing of Thus, a three-claw bezel is obtained very easily and rapidly as shown diagrammatically in FIG. 7e.
  • FIGS. 8a, 8b and 8c illustrate diagrammatically a modified form of embodiment of the milling operation wherein the rod 1 is still kept stationary in a vertical position while a vertical movement of translation is applied to the horizontal axis 14 of rotation of the milling cutter 13.
  • FIG. 8d illustrates diagrammatically the three-claw bezel obtained through this operation.
  • the metal rod 1 in which the bezel is turned and cut is constantly clamped in a rotary head-stock (not shown).
  • a considerable degree of precision is obtained in the positioning and centering of rod 1, so that the end product, i.e. the bezel, is characterized by a high degree of precision and finish.
  • FIG. 9 illustrates a bezel 17 obtained from a head 5 (FIG. 3) of cylindro-conical configuration, which has three triangular claws 16 formed therein.
  • FIG. illustrates a bezel 18 obtained from a cylindro-conical head 8 and comprising four claws 16 of rectangular configuration.
  • FIG. 11 shows a bezel 19 obtained from a biconical head 9 and comprising six claws 16.
