Definitions
- the present invention relates to an anti-gallop device for a clock escapement, this escapement comprising, inter alia, a spiral composed of several turns and a rocker provided with at least one arm, the rocker being pivotally mounted between a plate and a bridge, said device comprising a finger fixed on the arm of the balance, two columns between which can pass the finger when the pendulum is in motion, these columns being integral with the bridge of said balance, and a locking arm fixed on the outer turn of the spiral, this locking arm being capable of being interposed between said columns and said finger to prevent the rotation of the balance beyond an angle exceeding its normal operating angle.
- This device is implemented in so-called expansion escapements that are suitable for large timepieces such as marine chronometers. These parts are appreciated for their great precision, which is why it is very often called a relaxation exhaust itself renowned for its high accuracy.
- This exhaust has an important defect, namely its sensitivity to shocks. Because of this, it is considered not to be well suited to wristwatches. Indeed a shock applied to the timepiece can cause the pendulum to rotate beyond a normal operating angle. It then occurs a gallop because two clearances and two pulses occur during the same alternation.
- the present invention besides it obeys the generic definition in the first paragraph of this description, is remarkable in that the locking arm is a clamp attached to the outer coil of the spiral.
- FIGS. 1 and 2 show only the elements necessary for the understanding of the invention namely a spiral 1 composed of several turns 9 and 10 and a rocker 2 provided with at least one arm 3 and pivotally mounted between a plate (not shown) and a bridge 4.
- the detent escapement further comprises the following elements not shown in the drawings, namely: an escape wheel provided with generally pointed teeth which rest in turn on a pallet of rest, a rocker blocker recalled by a spring, this blocker carrying at its first end said pallet rest and at its second end a first actuating finger capable of being actuated by a second actuating finger carried by a plate integral with the balance, this plate also carrying a pallet of pulses adapted to receive pulses from the teeth of the escape wheel.
- the rest pallet is disengaged from the tooth of the escape wheel and one and other teeth of the same wheel, acting on the impulse pallet gives a pulse to the pendulum.
- the second actuating finger is arranged so as to actuate the first finger of the blocker only in a direction of rotation of the balance, that is to say during the first alternation of the oscillation then what takes place the impulse.
- the first finger of the blocker is not actuated because the second finger carried by the plate is arranged for s' then hide from what no impulse occurs.
- the anti-gallop device proposed in the work cited above and illustrated in Figures 1 and 2 of the present invention comprises a finger 5 fixed on the arm of the balance 2 and two columns 6 and 7 between which can pass the finger when the pendulum is moving, these columns being secured to the bridge 4 of the pendulum.
- the device also comprises a locking arm 8 fixed on the outer turn 10 of the hairspring 1. As shown particularly in FIG. 2, this locking arm 8 comes to interpose between the columns 6 and 7 and the finger 5 to prevent the rotation of the balance 2 beyond an angle exceeding its normal angle of rotation.
- the present invention is remarkable in that the locking arm 8 is a clamp attached to the outer turn 10 of the hairspring 1.
- This method is perfectly adapted to small spirals that we meet in wristwatches for example.
- the system envisaged does not require any complicated preparation and machining of the locking arm as is the case of the arm in the cited work.
- the clamp can be placed on the outer turn without difficulty, at the desired location, without the need to put on the spiral and fix it on the latter as provided in the same book.
- the clamp 8 can be in various forms including that which is illustrated in Figures 2 and 3.
- the clamp has the shape of an X whose upper branches 11 and 12 are shaped to hug the spiral.
- Figure 3 shows particularly that the upper branches are cut in the form of beveled jaws to tighten well on the spiral.
- the lower branches 13 and 14 are arranged to serve as means for gripping and placing the clamp.
- a tool specially designed for this gripping and positioning will allow gripping the gripper by its branches 13 and 14 and then bringing them together to elastically separate the upper branches 11 and 12 to install them on the hairspring. It will be understood that this clamp 8 can be made from a blade by simple stamping or chemical etching.
- the two columns 6 and 7 integral with the bridge 4 could consist of two pins driven in this bridge.
- the present invention however provides for simplifying this passage by proposing, as shown in Figures 1 and 2, a gantry 15 whose two columns 6 and 7 are connected by a cross member 16, this cross member carrying a rod 17 driven into the bridge 4 of the pendulum 2.
