Definitions

  • the subject of the invention is a timepiece with a mechanism for indicating the power reserve, comprising a mechanism driven by the relative movements of the barrel and the ratchet to indicate and display the number of days or hours of the reserve. of the timepiece.
  • a large number of devices are known that make it possible to indicate the power reserve of a timepiece, in particular a wristwatch, in which a differential mechanism is used driven by the relative displacements of the barrel and the ratchet and thus to enable displaying the power reserve of the timepiece according to a number of hours or days corresponding to a lapse of time during which the timepiece will operate without intermediate winding.
  • the object of the invention described below is to use a particular barrel construction to greatly simplify the mechanism for indicating the power reserve of the timepiece while improving its reliability.
  • the timepiece with its mechanism for indicating the power reserve is characterized in that it comprises 2 barrels placed face to face and having a common shaft and a bung so as to make them integral with one of the the other, the first barrel being used as a ratchet and the second meshing directly with the wheel of the counter wheel to control the escapement and the oscillator of the timepiece, the common axis of the two barrels directly attacking a rake connected to a axis of the display mechanism of the power reserve.
  • the rake of the power reserve mechanism is driven by 2 pins housed at the end of the shaft connecting the 2 barrels.
  • the rake of the power reserve mechanism can be driven by a gear placed at the end of the shaft.
  • the axis of the power reserve mechanism may have a needle moving over an area indication of the power reserve appearing on the dial of the timepiece.
  • the winding mechanism of the timepiece may include a winding rod engaged with a gear train arranged to rotate the barrel used as a ratchet, or a disc or cylinder placed behind a window of the dial.
  • the mechanism for indicating the power reserve shown in the drawing with reference to FIGS. 1 and 2 has been developed for a wristwatch. However, this use is not limiting and the mechanism for indicating the power reserve described can be used to equip pocket watches, or even clocks.
  • the timepiece comprises two barrels 1 and 2 respectively pivoting on a barrel shaft 3 and a plug 4 screwed onto the shaft, so as to make the two barrels 1 and 2 integral.
  • the barrels 1 and 2 each contain an identical barrel spring, not shown.
  • the barrel 1 is used as a ratchet and is rotated when the winding is carried out by means of a winding rod 5 and a gear mechanism 6, 7 and 8.
  • the barrel 2 normally meshes with the first mobile 9 of the counter wheel of the timepiece and thus transmits the energy necessary for the operation of the escapement and the oscillator.
  • the person skilled in the art easily understands that between the maximum arming and the complete disarming of the barrels 1 and 2, the number of laps completed is the addition of the numbers of revolutions of each of the barrels. But because the two barrels 1 and 2 contain identical springs, their number of turns of development are equal and therefore, during the time between the maximum arming and the complete disarming, the barrel shaft performs only half the total number of turns. For example, if each barrel has 12 turns of development, the barrel shaft 1 and 2 makes 12 turns in total.
  • This feature allows in operation to use the rotation of the common cylinder shaft to drive the power reserve indicator 10 in the extremely simple execution of the FIG. 2 in the form of a rake 10a driven by 2 pins 11 and 12 housed at the end of the barrel shaft 3. These two pins 11 and 12 cause the rake to execute a displacement of a tooth every half turn of the tooth. barrel shaft, as shown in the drawing. It is obvious to those skilled in the art that other embodiments using conventional gears or any other form of friction reduction are of course conceivable.
  • the power reserve mechanism 10 which has just been described is extremely simple and consists mainly of the rake 10a attached to the axis 13, which carries the needle 14.
  • the rake is driven directly by the barrel shaft 3 to by means of the two pins 11 and 12 fixed to the end of the shaft 3 along the axis of this shaft with a spacing corresponding to the teeth of the rake 10a.
  • This extremely simple construction of the power reserve mechanism 10 greatly improves the reliability and strength of said mechanism.
