Definitions

  • the present invention relates to a natural escapement for a clock movement, also known as a tangential impulse escapement.
  • the present invention relates more particularly to a natural escapement protected against damage that may be caused by premature triggering of the escapement impulse in the absence of the balance.
  • the present invention also relates to a clock movement comprising such an escapement.
  • Breguet's natural escapement The principle of the natural escapement was invented by Abraham Louis Breguet at the beginning of the 19th century.
  • the advantage of Breguet's natural escapement is that it is a free escapement, since the balance wheel is only disturbed by the operation of the escapement for a small fraction of its oscillation.
  • Breguet's natural escapement also has the advantage of giving each alternation a direct and tangential impulse to the balance wheel. In other words, the energy is transferred directly from the escapement wheel to the balance wheel, without passing through an anchor. Furthermore, the energy is transmitted only tangentially, so that the friction generated by the operation of this escapement is limited.
  • a natural escapement does not have a lost stroke in its function of maintaining the oscillations of the balance wheel; it delivers a similar impulse at each alternation, in a symmetrical and more uniform manner, so that mechanical energy losses due to lost strokes are eliminated. All these qualities make the natural exhaust potentially one of the most efficient exhausts.
  • the document CH 712 631 A1 discloses a natural escapement having an anchor with additional lifts. These lifts have the function of retaining stops acting on the escapement wheel.
  • the present invention aims to overcome the above-mentioned and other problems by providing a natural escapement for a clockwork movement that is protected against the effects of triggering the escapement function when the balance wheel is not present.
  • the present invention relates to a natural escapement for a watch movement performing a succession of operating cycles each composed of a first and a second alternation of a balance wheel during which the balance wheel moves from a first extreme position to a second extreme position passing through a middle rest position, then from its second extreme position to its first extreme position passing through its middle rest position a second time, this balance wheel comprising a balance wheel on an axis of which a balance wheel plate is adjusted, this natural escapement comprising a first escape wheel provided with at least a first toothing, this first escape wheel, arranged to be driven by a wheel of the clockwork movement, in turn driving a second escape wheel provided with at least a second toothing, the first and second escapement wheels forming a kinematic chain arranged to cooperate with an anchor capable of pivoting about an anchor stem, the balance wheel causing the anchor to pivot at each of the first and second vibrations, this anchor being arranged to block respectively the first and second escapement wheels temporarily during the second and first vibrations of an operating cycle, the
  • the invention also relates to a clockwork movement comprising a natural escapement of the type described above.
  • the present invention provides a natural escapement protected against damage that can be caused by premature triggering of the impulse.
  • the first escapement wheel is advantageously ensured to rest when, in the absence of the balance wheel, this rest is not ensured by the cooperation between this balance wheel and the anchor.
  • the second escapement wheel is not retained by the escapement function and can therefore rotate without control, which can cause a loss of the timekeeping function with an undesired advance, or even a sudden stop after acceleration of the gear train of the watch movement which may lead to deterioration of the components of the gear train and the escapement.
  • the first and second safety levers are arranged so that, in the absence of the balance, the second escapement wheel, by acting on the second safety lever, causes the pivoting of the second arm of the anchor, the anchor and the first arm of the anchor to ensure the resting of the first escapement wheel on the part of this anchor which, in normal times, i.e. when the balance wheel plate is present, performs the function of a stop pallet to temporarily block the first escapement wheel during an operating cycle of the natural escapement.
  • the first and second safety levers are designed so as not to be in contact with the first and second escapement wheels during normal operation of the escapement during which it is the balance wheel plate which causes the pivoting of the anchor.
  • the present invention proceeds from the general inventive idea which consists in providing the first and second arms of the anchor of a natural escapement, also known by its name tangential impulse escapement, with a first and a second safety lever in order to guarantee that, if the watchmaker, for any reason, needs to remove the balance wheel, an unexpected triggering of the rotation of the first and second escapement wheels is immediately stopped by bringing one of the first and second escapement wheels into its rest position.
  • a natural escapement also known by its name tangential impulse escapement
  • the safety levers are arranged so that, when the balance wheel is removed, the second escapement wheel, by action on the second safety lever, pivots the anchor and the first arm of this anchor to allow the first escapement wheel to come to a stop in its rest position resting against the part of this anchor which, in normal times, that is to say when the balance wheel is present, performs the function of a stop pallet to temporarily block the first mobile exhaust during a natural exhaust operating cycle.
  • the natural escapement is represented in its rest position at the figure 1 .
  • This natural escapement 1 is arranged to be driven by a wheel of the clockwork movement, for example a second wheel 2 which, according to a preferred but non-limiting embodiment, meshes with a pinion 4 fixedly mounted on an axis 6 of a first escapement wheel comprising a first escape wheel 10.
  • This first escape wheel 10 meshes via a first drive toothing 12 with a second drive toothing 14 of a second escapement wheel comprising a second escape wheel 16 which pivots about an axis 18.
  • the natural escapement 1 also comprises a balance wheel 20 which has a balance wheel 22 on an axis 24 from which a balance plate 26 is adjusted.
  • This balance plate 26 carries a balance pin 28 as well as a first and a second impulse pallet 30 and 32 whose respective roles will be described below.
  • the natural escapement 1 also comprises an anchor 34 pivoted around an anchor stem 36.
  • This anchor 34 comprises an anchor body 38 which carries a fork 40 formed of a first and a second horn 42a and 42b as well as a pin 44.
  • This pin 44 cooperates with the balance wheel plate 26 in order to prevent accidental movements of the fork 40 outside the periods commonly called additional arcs, periods during which the balance wheel plate 26 is close to its median rest position called the lift angle.
  • the anchor body 38 comprises a first and a second arm 46a and 46b which are preferably but not limited to arranged symmetrically on either side of the fork 40.
  • first and second levers 48a, 48b, pivoted about respective pivot axes 50 and 52, are connected to the first and second arms 46a, 46b of the anchor body 38 via a pivot joint 53.
  • the first lever 48a is made of one piece and has a geometry which provides the function of a first stop pallet for temporarily blocking the first escapement wheel 10 during an operating cycle of the natural escapement 1
  • the second lever 48b has a geometry which provides the function of a second stop pallet for temporarily blocking the second escapement wheel 16 during the same operating cycle of the natural escapement 1.
  • the first and second levers 48a, 48b each carry a lug 54, respectively 56, which projects into an oblong opening 58, respectively 60, formed in the first and second arms 46a, 46b of the anchor body 38.
  • the lugs 54 and 56 could be carried by the first and second arms 46a, 46b, and the oblong openings 58, 60 could be formed in the first and second levers 48a, 48b.
  • the first and second levers 48a, 48b are able to pivot relative to the first and second arms 46a, 46b of the anchor body 38.
  • the second wheel 2 which supplies the natural escapement 1 with the energy necessary for its operation rotates in a clockwise direction.
  • the second wheel 2 therefore tends to rotate the pinion 4 and the first escapement wheel 10 on the axis 6 of which the pinion 4 is fixed in an anticlockwise direction, and the second escapement wheel 16 in a clockwise direction.
  • An operating cycle of the natural escapement 1 comprises two alternations during which the balance wheel plate 26 will go successively from a first extreme position to a second extreme position passing through a median rest position, then from its second extreme position to its first extreme position passing through its median rest position a second time.
  • the balance wheel 26 rotates towards its middle rest position by rotating clockwise, while the second escape wheel 16 rests on the second lever 48b.
  • the balance wheel 26 arrives in a position in which it abuts by its balance pin 28 against the second horn 42b of the fork 40 and begins to cause the pivoting of the anchor 34 in the counterclockwise direction.
  • the pivoting of the anchor 34 in the counterclockwise direction has the effect of beginning to release the second escapement wheel 16 from its engagement with the second lever 48b, which will allow the second wheel 2 to drive, via the first escapement wheel 10, the second escapement wheel 16 in the clockwise direction.
  • the natural escapement 1 is in a position in which the balance wheel 26 drives the anchor 34, which causes the start of the first fall by disengaging the second escape wheel 16 from its engagement with the second lever 48b.
  • Fall is meant the periods of operation of the natural escapement 1 according to the invention during which the first and second escape wheels 10 and 16 are not in contact with either of the first and second levers 48a, 48b, or with either of the first and second impulse pallets 30, 32.
  • the first escapement wheel 10 also begins to give a driving impulse to the balance wheel 26 via a tooth 66 of an impulse and rest toothing 68 which drives the first impulse paddle 30 (see figure 4 ).
  • This driving impulse is called direct and tangential because it is given directly by the first escapement wheel 10 to the balance wheel plate 26 and the path of the tooth 66 catches up with that of the first impulse pallet 30 of the balance wheel plate 26 tangentially, which allows for almost punctual and frictionless contact.
  • the arrival of the tooth 66 of the first escapement wheel 10 in contact with the first impulse pallet 30 of the balance wheel plate 26 marks the end of the first fall.
  • FIG 5 is a top view of the natural escapement 1 in its position in which the first escapement wheel 10 imparts the impulse to the balance wheel 26, while the second lever 48b pivots about its pivot axis 52 and comes to bear against the second limiting stop 64.
  • This movement is controlled by the anchor 34 which, driven by the balance pin 28, pivots about its anchor stem 36 in an anticlockwise direction.
  • the first escape wheel 10 finishes giving an impulse to the balance wheel 26, which marks the start of the second fall. It can be seen that the tooth 66 of the first escape wheel 10 will no longer be in contact with the first impulse pallet 30 of the balance wheel 26. Furthermore, the second lever 48b is resting on the second limiting stop 64.
  • FIG 7 is a top view of the natural escapement 1 in its other rest position in which the first escape wheel 10 rests on the first lever 48a, which marks the end of the second fall, while the balance wheel 26 finishes its alternation freely by rotating clockwise.
  • FIG 8 is a top view of the natural exhaust 1 of the figure 1 in the case where the balance 20 has been removed, a situation schematically illustrated by representing the balance 20 in dotted lines.
  • the first and second levers 48a, 48b of the anchor 34 are respectively provided with a first safety lever 84 and a second safety lever 86.
  • the natural escapement 1 is in the position in which the second escapement wheel 16 will, by pivoting clockwise, act by one of the teeth of its impulse and rest toothing 70 on the second safety lever 86 carried by the second lever 48b and cause the pivoting of the anchor 34 to ensure the rest or blocking of the first escapement wheel 10 by pressing one of the teeth 66 of its impulse and rest toothing 68 on the part 88 of this anchor 34 which, in normal times, that is to say when the balance wheel 26 is present, ensures the function of a first stop pallet to temporarily block the first escapement wheel 10 during an operating cycle of the natural escapement 1.
  • the situation illustrated in the figure 9 is symmetrical to that represented in the figure 8 , namely that it is the first escapement wheel 10 which, by pivoting counterclockwise, will act on the first safety lever 84 carried by the first lever 48a and cause the pivoting of the anchor 34 to ensure the rest or blocking of the second escapement wheel 10 by pressing one of the teeth of its impulse and rest toothing 70 on the part 90 of this anchor 34 which, in normal times, that is to say when the balance wheel plate 26 is present, ensures the function of a second stop pallet to temporarily block the second escapement wheel 16 during an operating cycle of the natural escapement 1.
  • first and second levers 48a, 48b are not essential, the anchor 34 being able to comprise only the arms 46a, 46b, the first arm 46a having a geometry which ensures the function of a first stop pallet for temporarily blocking the first escapement wheel 10 during an operating cycle of the natural escapement 1, and the second arm 46b having a geometry which ensures the function of a second pallet. stop to temporarily block the second escape wheel 16 during the same operating cycle of the natural escapement 1.
  • a reduction wheel can be arranged between the second escape wheel 2 and the first escape wheel 10.
  • the first escape wheel 10 comprises a first drive toothing 12 by which it meshes with a second drive toothing 14 of the second escape wheel 16.
  • first and second escape wheels 10, 16 each comprise an impulse and rest toothing 68, 70 by which they provide a direct and tangential driving impulse to the balance wheel 26.
  • the drive toothing 12, 14 and impulse and rest toothing 68, 70 of each of the first and second escape wheels 10, 16 extend in a single plane or in two parallel planes.
