Definitions
- the present invention relates to a device for adjusting the position of a lift mounted on an anchor an escapement from a watch movement for the purpose of adjustment of the penetration of the lift in the teeth the escape wheel, and more particularly a device allowing adjustment with precision of the micron order of this penetration.
- the escapement In watchmaking, we refer to the escapement as mechanism placed between the cogs of a movement and its regulator, for example the pendulum of the watch movement, this escapement having for function of maintaining the pendulum oscillations.
- the exhaust 1 comprises an escape wheel 2, a anchor 4, a large plate 6 carrying an ankle 8 and a small plate 10 provided with a notch 11, carried by the axis balance 12.
- the anchor includes two lifts such that 14 cooperating with the wheel 2 and a rod 16 is ending with a fork 17 with three cooperating teeth with large and small plates 6 and 10 respectively.
- These lifts 14 are each secured in a suitable housing 18 provided in the branches such as 19 of anchor 4 for example using a shellac (not shown).
- Fork 17 includes two teeth external such as 20 which cooperate with the pin 8 while the inner tooth or stinger 22 cooperates with the small tray 10 and prevents accidental spillage of anchor 4 during the additional swing of the pendulum (not shown).
- the movements of the anchor 4 are limited by pins or stops such as 24 on which the rod 16 abuts. In the rest position, the rod 16 presses on one of the two pins 24 of limitation. At this time, a 2d tooth of the wheel exhaust 2 is pressed against one of the lifts 14 as shown in Figure 1.
- the tooth inner 22 of the fork 17 is released from the notch 11 so that the pendulum is released and runs through its counterclockwise amplitude S until its energy is exhausted. The pendulum then resumes the direction schedule to clear the lift 14 of tooth 2d.
- the anchor After the impulse given on lift 14 by tooth 2d, the anchor travels empty a short distance, called the lost path, until the rod 16 comes up against the pin 24. The pendulum then traverses its amplitude and returns until the pin 8 of the large plate 6 drives the fork 17 which triggers the pulse next.
- This lost path is a way of ensuring that all the teeth of the escape wheel 2 can pass.
- the length of this lost path is a function of the penetration P of the tooth of the escape wheel 2 on the rest plane 27 of the lift 14, this penetration must be both sufficient to avoid release accidental escape wheel 2, for example during shock, and low enough to guarantee freeing the teeth of the escape wheel 2 completely operating circumstance in order to get a exhaust 1 having optimal efficiency.
- This device includes a setting on which the anchor finished is positioned and tightened. The laying is then placed on an electric stove to bring the shellac for securing the lift on the anchor at its softening temperature, generally 90 ° C. The operator then acts on the lift by pushing it into a either way using a tip to bring the desired correction, the value of the correction having been previously determined by a measurement method appropriate. The movement of the lift generates the displacement of the key of a comparator which is in contact with the lift, and the setting value is controlled by the movement of a hand on the dial a comparator.
- the main aim of the invention is therefore to remedy the disadvantages of the aforementioned prior art in providing a device for adjusting the position of a lift mounted on an anchor which is simple, precise, and which does not risk damaging the lifts, thus allowing facilitate optimization of exhaust efficiency, that is to say the increase in the amplitude of the organ regulator with which it is associated.
- the invention relates to a device for adjusting the position of a lift mounted on an anchor for adjusting its penetration into the teeth of a escapement wheel of a watch movement, the device being characterized in that it comprises a frame fixed associated with a mobile carriage in translation according to a axis, means for controlling the movement of the carriage, means for measuring the movement of the carriage relative to the frame, means for fixing the anchor to the frame or the carriage and means for fixing the lift respectively on the carriage or the frame.
