Definitions

  • the present invention relates to a coaxial escapement of a part including first and second mounted escape wheels coaxially the first on the second, an intermediate wheel resulting in meshing said exhaust wheels, a balance plate carrying a ankle plate and an impulse pallet arranged to cooperate with the teeth carried by the second escape wheel, and an anchor located at the first escape wheel, this anchor having a fork cooperating with the plateau pin, a pulse paddle arranged to cooperate with the teeth first escape wheel, and first and second pallets of rest arranged to cooperate with the teeth of the second escape wheel.
  • FIGS. 1 and 2 of this description which represents the prior art.
  • the wheel 2 provides a dual function: that of an escape 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 escape pinion that would overcome the wheels 2 and 3 and would increase the height of the assembly as is the case description of the cited patent.
  • the functioning of the improved version is similar to that of the cited patent.
  • the pulse at plate 5 of the balance is delivered by the escape wheel 3 via the pallet 7 of the plate 5, while the impulse via the anchor 1 'is given by the wheel exhaust 2 via the pallet 10 and the fork 9 of the anchor 1 '.
  • the wheel 3 is blocked by one of the pallets of rest 12 'or 13' of the anchor 1 '.
  • the present invention is innovative in that each of the first and second pallets of rest being made of a stone monobloc engaged in a groove made in the anchor in known manner, said piece exceeds one of the plane faces of the anchor and has a height specific to bring it to the level where the second escape wheel evolves 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 is associated 1 according to the invention.
  • the coaxial escapement includes a first exhaust wheel 2 mounted coaxially on a second 3 exhaust wheel, which it is attached.
  • An intermediate wheel 4 which can be the last of the finishing train driven by the barrel, turns in the direction of the 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 is connected the conventional oscillator formed of the pendulum and the spiral (not shown).
  • the tray 5 carries a plateau pin 6 and a pallet 7 pulse. 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 has a fork 9 which cooperates with the ankle 6 of the plate 5.
  • the anchor comprises still a pulse pallet 10 arranged to cooperate with the teeth 11 of the first escape wheel 2.
  • the anchor finally has first 12 and second 13 pallets of rest arranged to cooperate with the teeth 8 of the second escape wheel 3.
  • each of the first 12 and second 13 pallets rest is made of a one-piece 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 made in a post 26 itself introduced into the anchor 1 '.
  • the stones 12 and 13 exceed one of the plane faces 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 cooperate with the teeth 8 of said second wheel. So we understand that, by this arrangement, stones 12 and 13 are directly related to the anchor 1 without intermediate artifice.
  • Figure 5 is an enlarged plan view of the extreme part. anchor 1 which contains the fork 9 and figure 6 an enlargement of the zone VI of FIG.
  • Figure 5 shows the fork 9 provided with its horns, the ankle 6 of plateau inserted between the horns, and a dart 30, the latter being also represented in FIG. 3.
  • the inner flaps 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 inner faces 16 and 17 of the fork 9 (pans drawn in solid lines) is increasing as and as you approach the bottom 18 of the range. This so-called provision asymmetric provides an advantage that will now be explained.
  • FIGS. 5 and 6 also have non-parallel faces 16 and 17, parallel sections 16 'and 17' drawn in dotted lines and which are of use in known constructions.
  • In standard constructions with panels symmetrical, and at the moment when the anchor 1 receives a pulse in the direction of arrow A, there is a contact at point 31 between! e pan 17 'and the ankle 6.
  • In the construction of the invention with non-parallel flanges and at the moment where the anchor 1 receives a pulse in the direction of the same arrow A, it is produces a contact at point 32 between pan 17 and ankle 6.
  • the contact 32 is therefore higher on the periphery 33 of the ankle 6 than was the point of contact 31 on the same circumference 33.
  • the invention allows to win the path that separates points 31 and 32 in the process of exit from the ankle 6 of the fork 9.
  • the friction path that exists between the initial point of contact 32 and the point of separation of the ankle from with the pan 17, at the exit of said ankle, is thus shortened of the distance B that separates points 31 and 32.
  • a second additional improvement is to lubricate the pivots 20 and 21 of the shaft 19 which carries the anchor 1 (see Figure 4).
  • This lubrication has always been avoided until today for fear of natural deterioration of the oil used. Without oil, however, there is a phenomenon of fretting corrosion "which is a wear caused to dry friction on mobiles affected by small movements or vibrations. This results in a production of iron oxide tending to seize the mechanism.
