  • the plate 43 continuing its travel in the direction of the arrow 47, the blocker then inclines to the wheel B which releases the tooth 50 of the pallet S1 rest then almost simultaneously engages the tooth 49 on the pallet of rest C of the blocker 40. There is transfer of rest of S1 with C, the wheel B then turning on a small angle in the clockwise direction the time of this transfer.
  • the present invention in addition to that it obeys what is described in the first paragraph of this description is remarkable in that the blocker carries first and second pallets of rest arranged to cooperate respectively with the first and second wheels, the blocker having a rod whose end cooperates with the plate pin, the axis that has the rod cutting at the same time the axis of the pivot of the plate and the axis of the pivot blocker when the first and second wheels are at rest on the first and second pallets of rest, said blocker still having means for reengagement of the first and second pallets of rest respectively in the first and second escape wheels.
  • the figure 2 is a plan view of the mechanism of the two-wheeled escapement according to a first embodiment of the invention.
  • This exhaust comprises first and second escape wheels 1 and 2 each driven by gear wheels and independent barrels.
  • wheel 1 rotates clockwise while wheel 2 turns counterclockwise.
  • the figure 2 shows a plate 4 articulated on a pivot 3.

  • Other ways of making these pallets of rest or locking means are possible and described in detail in the document EP-A-1'708'047 .
  • the plate 4 rotates in the direction of the arrow 60.
  • the wheels 1 and 2 are at rest on the pallets 12 and 13, respectively by their teeth 61 and 62 locked on the lines of rest 28 and 29.
  • the pin 7 enters into contact with the end 15 of the strip 14 of the blocker 8.
  • This blocker is centered with respect to the wheels, that is to say that the axis 17 of its strip 14 intersects the axes of the pivots 3 and 9 of the plate and the blocker respectively, as has already been said about the figure 2 . This is the beginning of the release of wheel 1.
  • the plate 4 has continued its course in the direction of the arrow 60.
  • the pin 7 has driven the blocker 8 in the direction of the arrow 63 forcing the tooth 61 of the wheel 1 to climb the plane 24 of the wafer 20 composing the pallet 12.
  • the wheel 1 undergoes a slight recoil movement caused by this escalation indicated by the arrow 64.
  • the tooth 62 of the wheel 2 has climbed the plane 27 of the plate 23 forming the pallet 13 forcing the wheel 2 to a slight decline indicated by the arrow 65. It is the end of the release and the beginning of the release of the wheel 1.
