Definitions
- the present invention relates to a one-piece coaxial exhaust timepiece comprising first and second escapement wheels mounted coaxially the first on the second, an intermediate wheel meshing with the first escape wheel, a balance plate carrying a plateau pin and a pulse paddle arranged for cooperate with the teeth carried by the second escape wheel, and a anchor located at the first escape wheel, this anchor comprising a fork cooperating with the plate pin, a pallet impulse arranged to cooperate with the first wheel teeth exhaust, and first and second rest paddles arranged to cooperate with the teeth of the second escape wheel.
- FIGS. 1 and 2 of the present description which represents the prior art.
- the height of wheels 2 and 3 of the coaxial exhaust can be considered a disadvantage for using this escapement in watches extra-flat, G. Daniels imagined an execution without an exhaust gear as was also the case with the execution set out in the patent cited more high.
- the wheel 2 provides a double function: that of the exhaust pinion meshing with the intermediate wheel 4 and that of the escape wheel cooperating with the pallet 10 of the anchor 1, which saves an exhaust pinion which would overcome the wheels 2 and 3 and would increase the height of the assembly as is the case with the description of the cited patent.
- the functioning of the version improved is similar to that of the cited patent.
- the impulse to the plate 5 of the balance wheel is delivered by the wheel exhaust 3 via pallet 7 of plate 5, while the pulse by via the anchor 1 'is given by the escape wheel 2 via the pallet 10 and fork 9 of anchor 1 '.
- the wheel 3 is blocked by one of the rest pallets 12 'or 13' of the anchor 1 '.
- each of the first and second rest pallets is made of a monobloc stone engaged in a groove made in the anchor, said part projecting beyond one of the planar faces of the anchor and having a proper height to bring it to the level where the second wheel moves exhaust to cooperate with the teeth of said second wheel.
- Figures 3 and 4 show in perspective, respectively seen from above and below the coaxial escapement with which the anchor 1 is associated according to the invention.
- the coaxial exhaust includes a first escape wheel 2 mounted coaxially on a second exhaust wheel 3, of which it is integral.
- An intermediate wheel 4 which may be the last of the finishing train driven by the barrel, turns in the direction of arrow F and transmits the driving force to the first wheel 2 exhaust with which it meshes.
- Figures 3 and 4 show a platform 5 of the pendulum to which the conventional oscillator formed of the pendulum is linked and hairspring (not shown).
- the plate 5 carries a pin 6 of the plate and a pulse palette 7. This pallet 7 is arranged to cooperate with the teeth 8 of the second escape wheel 3.
- the anchor 1 is located at level of the first escape wheel 2.
- the anchor 1 comprises a fork 9 which cooperates with the pin 6 of the plate 5.
- the anchor comprises another pulse palette 10 arranged to cooperate with the teeth 11 of the first escape wheel 2.
- the anchor finally comprises first 12 and second 13 rest paddles arranged to cooperate with the teeth 8 of the second escape wheel 3.
- the anchor 1 according to the invention is remarkable in that each of the first 12 and second 13 pallets rest is made of a monobloc stone engaged in a groove 14 practiced in the thickness of the anchor 1, which distinguishes it from the prior art shown in Figure 2 where the pallet 12 'is engaged in a groove 27 practiced in a tenon 26 itself introduced into the anchor 1 '.
- the stones 12 and 13 project beyond one of the planar faces of the anchor 1, in this case the face 15, and have a height such that they extend to the level where the second escape wheel 3 evolves to cooperate with the teeth 8 of said second wheel.
- stones 12 and 13 are directly linked to anchor 1 without intermediate device.
- Figure 5 is an enlarged plan view of the end portion of the anchor 1 which contains the fork 9 and FIG. 6 an enlargement of the zone VI of figure 5.
- FIG. 5 shows the fork 9 provided with its horns, the pin 6 of tray introduced between the horns, and a dart 30, the latter also being shown in Figure 3.
- the inner sections 16 and 17 of the fork 9 are rectilinear - this which is commonly the case - and not parallel - which is new.
- FIG. 5 shows that the distance d separating the internal panels 16 and 17 from the fork 9 (sides drawn in solid lines) increases gradually as as we approach the bottom 18 of the fork. This so-called provision asymmetrical brings an advantage which we will explain now.
- FIGS. 5 and 6 also show non-parallel sections 16 and 17, parallel sections 16 'and 17' drawn in dotted lines and which are used in known constructions.
- the anchor 1 receives a pulse in the direction of arrow A
- the anchor 1 receives a pulse in the direction of the same arrow A
- the point of contact 32 is therefore higher on the periphery 33 of the pin 6 than does was the point of contact 31 on the same periphery 33.
- the invention allows to gain the path that separates points 31 and 32 in the process of outlet of pin 6 of fork 9.
- the friction path that exists between the initial contact point 32 and the ankle separation point with the pan 17, at the exit of the said ankle, is therefore shortened by the distance B which separates points 31 and 32.
- it has been observed in the coaxial exhaust a more friction path as long as the existing path on a conventional exhaust. The improvement proposed is therefore all the more justified, although it could also be implemented on said conventional exhaust.
- a second additional improvement consists in lubricating the pivots 20 and 21 of the shaft 19 which carries the anchor 1 (see FIG. 4). This lubrication has always avoided until today for fear of natural deterioration of the oil used. Oil free however i! a fretting phenomenon occurs corrosion "which is wear caused by dry friction on mobiles affected by small movements or vibrations. This results in a production iron oxide tending to seize the mechanism. We discovered however that with the oils known today, very liquid and not thickening, you can safely use them to oil the anchor pivots.
