Definitions

  • the subject of the invention is an anchor of an escapement for timepiece.
  • the anchor In an escapement timepiece, the anchor includes two arms and a rod, at the end of which is a fork. This range is constituted by an input horn, an output horn, and a stinger usually chased in the fork, the dart being angularly equidistant from the two horns.
  • the stinger is secured to a finger or a shaped pin cylindrical, driven into a hole of corresponding shape placed on the fork.
  • the rooms being very small dimension, the hunting operation poses some problems. During this hunting operation, the risk of breakage is significant. Alternatively, if the link between the sting and the fork is too free, the sting can take off. On the other hand, the position angle of the sting in relation to the fork must be checked and often corrected after the operation of chassage. These operations take time, and help increase the cost of parts.
  • the darts can be set up with electric solder, tin or laser, or by bonding. In the case of a weld, the anchor is no longer removable, and the risks during the hunting operation is not eliminated.
  • the object of the present invention is to eliminate the disadvantages outlined above, and to propose a anchor in which the angular position of the stinger does not no more adjustment required after the chassage.
  • the anchor of a timepiece escapement comprising two arms, a rod, a fork and a sting chase frictionally in a scope of the fork, is characterized in that the fork and the sting are assembled by through a male part and a part female, of complementary shapes and arranged for satisfy a predetermined and oriented positioning of the sting against the fork.
  • the male part and / or the female part of the assembly have a certain elasticity to avoid breakage during the hunting operation.
  • the female part of the assembly may have cutouts around the orifice in the solid part of the room.
  • the male part of the assembly is attached to the sting.
  • the reverse is also possible, and the male part of the assembly can, in in some cases, be in solidarity with the fork.
  • the male part and / or female have complementary forms allowing only one possibility of assembly. This measure opens the door to any possibility of assembly automatic.
  • the assembly can be completed by an operation applying hardening wax at a temperature given, the wax may be shellac.
  • the anchor shown in Figure 1 includes a rod 10 comprising at one of its ends a input arm 11 and an output arm 12 as well as a pivot axis 13.
  • arms 11 and 12 carry the pallets 18 made of ruby and kept at friction at the end of arms 11 and 12.
  • Ruby pallets 18 are usually joined to the ends of arms 11 and 12 by the application of a droplet of lacquer intended to harden at room temperature.
  • the darts 15 represented in FIGS. 2 to 9 are intended to be assembled with bores in the corresponding forks or sticks, by a male part 20, respectively 21 (FIG. 8), integral sting 15.
  • Figure 10 there is shown a bottom view of the fork 14, showing a male part 20 of the sting 15 driven into a corresponding bore 30 of the fork.
  • the sting 15 shown in Figure 10 corresponds to the dart of figure 2 with its male part 20 cylindrical, and its lug 22.
  • the male parts 20, respectively 21 of the darts can present different configurations.
  • the darts have male parts 20 with a general cylindrical configuration and ribs or grooves of different shapes. It is evident that the corresponding female parts of the range will be in accordance with the configurations male darts so that they can be chased frictionally in the forks according to a predetermined and oriented positioning of the sting by relative to the fork 14.
  • the male parts 20, respectively 21 of the darts of FIGS. 2 to 9 likewise that the complementary female parts of the forks will be made so that the assembly presents a certain elasticity during the hunting operation, and allows to avoid breakage during this operation.
  • the darts 15 and their male part 20, respectively 21 are made of so that the hunting operation can be done without any adjustment.
  • the male parts 20, respectively 21, and the corresponding female parts 30 of the fork will be made so as not to allow only one possibility of assembly, the dart being in place, equidistant from the two horns, after the operation of hunting ( Figure 10). This allows mounting entirely automatic dart 15 on the forks 14.
  • Figures 11 to 36 show a lot of examples of female parts arranged to satisfy a predetermined positioning and oriented dart relative to the fork. It is obvious that the dart will correspond in figures 11 to 36 to the bores 30 of the fork, so that that this oriented mounting character requires no setting, be satisfied.
  • the bores 30 of Figures 11 to 36 have cutouts 32 for retaining the sting in the fork with a certain elasticity. Those skilled in the art can easily understand that the part central 30 of the bore is intended to receive a dart corresponding, while the cutouts 32 surrounding this central part, will allow to marry the shape of the male part of the sting without risk of breakage for the fork.
  • the sting 15 can therefore be chased in the female part 30 of the fork in a predetermined positioning and oriented requiring no adjustment.
  • male and female parts of the stinger will be chosen from way of presenting complementary shapes does allowing only one possibility of assembly. So the darts 15 and the forks 14 may be fully automatically assembled in robots designed for this purpose.
  • a wax hardening to a certain temperature can be applied hot on the dart-fork assembly.
  • a wax such as shellac for example, is advantageous because it allows the disassembly of the dart and, for example, replacing it on the anchor.
  • the stinger does not does not have to be united with the party male, but can also support the female part, the male part being mounted on the fork.
  • the sting may likewise present cutouts ensuring a certain elasticity to the whole.
