Definitions

  • the present invention relates to mechanical clockwork movements, particularly in watches, and it relates to certain provisions for reducing isochronism defects that result from imperfections of the control system of the watch.
  • the tourbillon invented two centuries ago by Abraham-Louis Breguet is a device that reduces isochronism defects resulting from the effects produced in particular by gravity on the regulating organs of the watch, because of the inevitable balancing defects of these organs. .
  • the oscillator and the escapement are mounted in a cage which rotates about an axis parallel to the axis of the balance-spring assembly, the component of the gravity which is exerted in the plane perpendicular to these axes performs a continuous rotation relative to these bodies, so that each tower of the cage leads to a compensation of the effects of imbalances in this plane and thus improves the regularity of the watch to wear, especially when the watch is in the vertical position.
  • vortex both devices in which the axis of the balance coincides with the axis of rotation of the cage (for example according to Breguet or according to the patent CH 262 017 ) and devices often called “carousels", where these axes are distinct (see for example patents CH 30 754 , CH 256 590 and EP 846 987 ).
  • the patent FR 2 784 203 presents yet another way of reinforcing the compensation produced by the vortex.
  • This one the barrel which drives it and the cogwheel connecting these two elements are mounted on a turntable making one turn per hour, whose axis of rotation is parallel to that of the tourbillon.
  • This arrangement forms a kind of swirl on a carousel, the vortex revolving around the center of the turntable.
  • CH 156 801 Another way of improving isochronism was formulated in the 1930s by M. Vuilleumier and published in the patent.
  • CH 156 801 consists in using two usual control systems each comprising a balance-spring and an escapement in a single clockwork movement, these two systems being coupled to the finishing gear train by means of a differential gearing fulfilling the dual function of distributing the energy drive the two systems equally and to moderate their progress to regulate the speed of the finishing gear.
  • This principle was not successful, probably because the theoretical gains were counterbalanced by yield losses in the extra workings, especially in the differential gearing.
  • different watchmakers have taken this principle to create watches with two or more vortices coupled by a differential gear. Such arrangements confer a prestigious appearance on these watches, but it remains to be seen whether they actually improve isochronism compared to a single vortex movement.
  • the subject of the present invention is a mechanical movement watch comprising at least two control systems each comprising a mechanical oscillator and an escapement, the control systems being mounted on a common support and connected to a device for displaying the common time by means of a intermediate differential gear, and aims to perfect such an arrangement in a way to improve the running of a watch.
  • An additional goal is to create a watch with a new look, highlighting the high technicality of its movement.
  • a watch according to the invention is characterized in that its movement comprises as many sub-assemblies as control systems, each of said subassemblies comprising a regulating system, a cylinder and a finishing gear train transmitting the energy of the cylinder to the regulating system inside the subassembly, and in that the differential gearing, said display, connects the barrel or the work train of each of said subassemblies to the display.
  • the differential gear is not used to distribute to the control systems the mechanical energy stored in the barrel springs, but only to advance the display members at a speed which is the average of those of the control systems. This gear thus transmits almost no effort and does not affect at all the performance of the workings of finishing.
  • the barrels are connected to each other and to a winding device by a differential winding gear.
  • a differential winding gear This not only has the advantage of making it possible to raise the two barrels together, but also to ensure a compensation of the arming between them, which tends to equalize the amplitudes of oscillation of the balances between the control systems.
  • the common support of the control systems can be fixed in the watch, but in more advanced versions, it can be formed by a turntable, which adds compensation for the effects of gravity on the imbalances as in a vortex. To obtain a particular aspect of the watch, it is expected that the turntable performs two turns per day and carries a hour hand.
  • control systems mounted on the turntable are two vortex systems, which adds to the basic effects of the invention the compensatory effects provided in the patent.
  • FR 2 784 203 to further improve the regularity of the watch. This principle is applied in the examples described below.
  • the simple arrows characterize gear trains without energy transmission to the control systems
  • the double-line arrows characterize gear trains with energy transmission to the control systems.
  • the symbol SR may represent both an ordinary mechanical regulating system and a rotating regulating system, in particular a vortex.
  • the upper part comprising the elements R, B, F, A and MH is the same as for a classic clockwork movement.
  • the single regulating system is replaced by a set comprising two control systems SR1 and SR1 and a finishing differential Df which distributes on them the engine torque and, at the same time, regulates the speed of the gear on the basis of the average speeds of the two control systems.
  • each regulating system SR1, SR2 is matched to a cylinder B1, B2 which drives it via a suitable gear train F1, F2, that is to say that each pair B1-SR1 and B2-SR2 form a subset SE1, SE2 which can have its own step, as if it were an independent clockwork movement.
  • These two subsets may be of identical construction.
  • the two barrels are permanently connected by a winding differential Dr whose input element is blocked. by a ratchet during the normal running of the watch.
  • the armature couples are balanced permanently through the differential Dr, which contributes to equalize the operation of the two control systems, in particular the oscillation amplitude of the rockers.
  • the movement made according to the diagram of FIG. 2 also includes the following features, contributing to increasing the isochronism in different positions of the watch.
  • the two control systems SR1 and SR2 are vortices.
  • the two subsets SE1 and SE2 are mounted on a turntable, a large part of which is visible on the upper face of the watch. The watch thus has an attractive and original appearance, presenting on the dial side two swirls that perform an orbital movement around the center of the watch while turning each on itself.
  • FIGS. 3 and 4 The general structure of the movement of the watch is illustrated by FIGS. 3 and 4.
  • the movement comprises a fixed plate 1 intended to be mounted in the watch case and bearing on its underside a time setting bridge 2.
  • On the upper face of the plate 1 is fixed the outer ring of a large ball bearing 3 centered on an axis 4.
  • the inner ring of this bearing carries a rotating support 5 comprising a rotating plate 6 on which are fixed a main bridge 7 and various other bridges to support the wheels.
  • a pointed end 9 constitutes the hour hand of the watch, moving next to a turn of hours located on an annular dial 10.
  • the bar 8 also carries the upper bearings of the two vortices 11 and 12, which are diametrically opposed relative to the axis of rotation 4 of the rotating support 5. Above the vortex 12, the bar 8 is provided with an annular portion 13 bearing a graduation of seconds facing a seconds hand 14 attached to the upper pivot of the vortex 12.
  • the two barrels are mounted on the rotating support 5 in order to drive each one of the vortices 11 and 12.
  • these barrels are hidden under the bridge 7, but the bearings 15 which support them in this bridge show their position in plan.
  • One 16 of the two barrels is visible in Figure 4, where one note that a wheel 18 is fixed to the barrel, while the shaft 19 of the barrel is provided with a ratchet 20.
  • the finishing gear train 31 comprises a mobile medium 40 and a mobile average 41.
  • the pinion 42 of the large average meshes with a peripheral toothing 43 16.
  • the wheel of the average wheel 41 is engaged with the second wheel 25 of the vortex 11, it rotates well under the action of the barrel.
  • the other work train 32 is of identical construction, with a mobile of medium 44 and a mobile of average 45.
  • FIGS. 4 and 5 also show cogs connecting each barrel 16, 17 to the display members through the display differential Da appearing in FIG. 2.
  • This is an epicyclic gearing of which one of the three elements main is formed by a barrel 51 provided with a gear 52.
  • the barrel 51 is the support element of the differential gear and usually does not rotate, but to allow the time setting is mounted so rotatable by means of a lower bearing 53 in the plate 1 and an upper bearing 54 in a bridge 55 of the rotating part.
  • a setting wheel 56 is fixed to the lower end of the barrel 51 and cooperates with a time setting wheel which will be described later and one of whose elements is immobilized by a friction device.
  • the second main element of the display differential Da is a planet carrier 60 composed of two parts, one of which is an input wheel 62 with external teeth.
  • a single satellite 64 provided with two teeth, one of which meshes with the wheel 52 of the barrel 51 and the other meshes with a pinion 65 secured to another wheel input 66 of the differential.
  • the two wheels 62 and 66 have the same diameter and play a symmetrical role, so that only half of each of them is shown in FIG. 5.
  • Wheel 66 is engaged with the wheel 18 of the barrel 16 via a return 67.
  • the wheel 62 of the differential is engaged with a wheel 68 of the barrel 17 via a return 69. If several satellites were provided at instead of one in this differential gear, the transmission of couples would not be better, because it would be mainly on one of them because of the inherent games clockwork.
  • the teeth of the satellite 64 and the corresponding teeth of the elements 52 and 65 are such that the input wheels 62 and 66 of the differential gear can rotate at equal and opposite speeds when the barrel 51 is stationary. But since these two speeds are each regulated by one of the vortices 11 and 12 and can therefore differ slightly because of momentary momentum deviations, the differential Da has the effect of averaging these two speeds in the speed of revolution of the support 5 carrying the bearings of the vortices and the wheels just described. This gives a regularity of operation (isochronism) which is better than that of each of the vortices.
  • the minute hand 70 shown in FIG. 3 is carried by a shaft 72 passing inside the barrel 51 and provided with a minute pinion 73 below the plate 1.
  • a conventional timer wheel 74 connects the pinion 73 to an hour wheel 76 fixed under the turntable 6.
  • the support 5 carrying the hour hand 9 which drives the shaft of the minute hand 70 with a transmission ratio of 12: 1.
  • the time setting mechanism will be described with reference to FIGS. 4 and 6. Unlike the use, it does not act at the level of the timer wheel, but on the wheel 56 integral with the barrel 51 which serves as a point of contact. support Da display differential, thus serving to define the angular position of the turntable 6.
  • the time is set from a winding rod 77 which carries a sliding pinion 78 controlled in a conventional manner by means of a pull tab 79 and a rocker 80.
  • the sliding pinion 78 meshes with a time-setting train 82 which connects it to the wheel 56.
  • This train comprises a first gear 83, an intermediate wheel 84 and a return wheel 85.
  • the lower end of the mobile 84 is mounted in the bridge 2 by means of a friction ring 86 which opposes a pair of restrained to any rotation of this mobile. It is this torque which, multiplied by the transmission ratio between the mobile 84 and the barrel 51, provides a bearing torque high enough to prevent rotation of the barrel 51 during the running of the watch. By against the friction torque offers little resistance to the rotation of the rod 77, thanks to the reduction between these two elements.
  • the central portion of the turntable 6 has a cylindrical protuberance 90 which serves as a hub for the three main elements of the winding differential Dr, namely a planet carrier 91 and two output wheels 92 and 93.
  • This differential is of the planetary type, its two satellites 94 meshing on an internal toothing of the wheel 92 and on a toothing of the central hub 89 of the wheel 93.
  • the wheel 92 drives the ratchet 20 of the barrel 16 via a gear train mounted on the plate 6, comprising a mobile 95 and a return 96.
  • the wheel 93 drives the ratchet 97 of the second cylinder 17 through a train comprising a mobile 98 and a return 99.
  • the diameters of the gear elements of the differential Dr and following wheels are determined so that the torque applied to the planet carrier 91 during reassembly is divided equally between the ratchets of the two barrels.
  • the planet carrier 91 can only rotate in one direction, because in the other direction it is blocked by a pawl 100 (FIG. 4) which pivots around a screw 109 mounted in a fixed position with respect to the turntable 6. Since this locking of the shafts of the two barrels is done at the entrance of the differential Dr instead of acting as usual directly on the ratchet of each barrel, the differential allows one of the barrels to transmit the energy to the other if it is more disarmed than the first, for example if the whirlpool associated with it has operated at a slightly higher frequency than that of the other vortex. This results in an equalization of the winding of the two barrels at all times, which contributes to equalize the amplitudes of oscillation of the rockers in the two vortices.
  • FIG. 4 a winding pinion 101 can be seen which can be driven by the sliding pinion 78 when the winding stem 77 is rotated.
  • FIGS. 7 and 8 show that the pinion 101 drives the planet carrier 91 by the intermediate of a winding train 102 which comprises a ring gear 103, an intermediate mobile 104 and a sliding pinion 105 which will mesh with the external toothing of the planet carrier 91 when the train rotates in the direction of reassembly.
  • FIG. 2 can be made both on a fixed plate and on a rotating support, and that in each case each system regulating SR1 or SR2 can be either fixed or rotating like a vortex, and can also be a tourbillon with several axes of rotation, in particular of one of the types mentioned in the introduction.
  • a person skilled in the art will also be able to design a movement with more than two regulating systems in applying the principles of the present invention, since a suitable differential gear allows more than two subsets such as B1-SR1 and B2-SR2 to be coupled to average their speeds on the display of the watch.
