Definitions

  • the present invention relates to a timepiece mechanical comprising an oscillator whose movement oscillation is serviced by a mainspring, in which a periodic energy storage device is arranged between this mainspring and an exhaust associated with said oscillator.
  • the energy source of mechanical timepieces is constituted by a motor spring consisting of a blade spring wound in a barrel, its outer end being integral with the barrel drum, while its end interior is integral with the shaft of this barrel.
  • the motor spring drives the drum of barrel.
  • This has an external toothing in engagement with the wheel of the timepiece that leads to the exhaust for transmitting the force of the mainspring to the regulator. With each alternation of the spiral balance, this one let out a tooth from the escape wheel which, under the pressure exerted on the wheel by the spring barrel, transmits a pulse serving to maintain the oscillation of the balance-spring.
  • these devices are not designed to be able to be housed in a watch, especially in a watch bracelet, but are rather intended for clocks in which the congestion problem does not present the same importance only in watches and especially in watches bracelets.
  • the object of the present invention is to provide a solution to the problem of the transmission of the spring force of a cylinder in the exhaust of a timepiece which at least partly to overcome the disadvantages above.
  • this invention relates to a part mechanical timepiece according to claim 1.
  • the first wheel of the usual wheel shown is the wheel of average 1 whose pinion meshes with the center wheel (not shown) itself provided with a pinion meshing with the toothing of the cylinder containing the mainspring, as in all parts mechanical timepieces.
  • This wheel of average 1 is driven in the direction of the arrow F 1 and meshes with the pinion of a first second wheel turning in the opposite direction shown by the arrow F 2 .
  • the pinion of this first wheel of seconds 2 meshes with a reference 4 which meshes itself with the pinion of a second wheel of seconds 5.
  • the pivot axis of this second seconds wheel 5 is attached to a whirlpool exhaust 8 classic that there is no need to describe here, insofar as it is not necessary for the understanding of the present invention.
  • the second wheel of seconds 5 could mesh with the pinion an exhaust wheel of a classic exhaust.
  • Return 4 is pivotally mounted on an equalizer 6 which is rotated about an axis coaxial with the axis of the second wheel of seconds 5.
  • This toggle 6 is subject to the force of a periodic energy storage spring 7, which tends to rotate it clockwise of a watch.
  • This flip-flop of equality 6 has a similar finger 6a in this form of execution to a pallet of an anchor an anchor escapement, intended to engage in a toothing ratchet of a stop wheel 3 whose pinion meshes with the first seconds wheel 2.
  • the operating cycle of the storage device periodical energy is as follows: When the pallet or the finger 6a of the equality flip-flop 6 is engaged with a radial flank of the ratchet toothing of the stop wheel 3, the gear 1-3 is stopped, so there is no more transmission of force between the first seconds wheel 2 and the return 4.
  • the force stored in the periodic energy storage spring 7 is released by rotating the equality lever 6 in the clockwise direction. until the pallet or the finger 6a of this equality flip-flop 6 is disengaged from the radial flank of the stopping wheel 3. During this movement, the flip-flop 6 transmits its energy to the pinion of the second wheel 5. Since the first seconds wheel 2 is stopped, when the equality flip-flop 6 rotates in the direction of clockwise, the return 4 causes the pinion of the second second wheel 5 in the direction of the arrow F 3 .
  • the reference 4 is therefore supported on the pinion of the second seconds wheel 5 and its drive in the direction of the arrow F 4 by the pinion of the first seconds wheel 2, pushes the pallet or the finger 6a of the latch equal 6 against the inclined side of one of the teeth of the stop wheel 3 rotating in the direction of the arrow F 5 , until it comes against the radial flank of the next tooth.
  • the rocker By following the inclined flank of the tooth of the stop wheel 3, the rocker therefore moves counterclockwise, causing the periodic energy storage spring 7 to be wound, since the force exerted by this storage spring 7 on the equalizer rocker 6 is less than the force exerted on the same rocker 6 by the mainspring when the stop wheel 3 is released.
  • cycle of arming and disarming equality spring 7 is not necessarily a second. It could be lengthened or shortened by changing the number of teeth of the stop wheel 3.
  • the exhaust 8 receives only the energy from disarming the equality spring 7 which is independent of the degree of winding of the mainspring.
  • the amplitude of the oscillations of the pendulum is independent of the force variations of the mainspring, which makes it possible to improve the isochronism of the pendulum.
  • the storage device described includes a small number of pieces.
