Definitions

  • the present invention relates to the field of mechanical watchmaking. It relates, more particularly, a timepiece comprising a double-ring mechanism.
  • the usual mechanisms of repetition to minutes make it possible to indicate, on demand, the hour to the minute, by means of blows struck by two hammers on two different stamps.
  • the hammers are operated by lifts that are raised by a striking mechanism. This includes a room of hours, a quarter and a minute, with twelve, three and fourteen teeth respectively to ring the hours, quarters and minutes.
  • a snail of the hours is arranged on a star with twelve teeth, advancing one step per hour, while a quarter snail and another minute are adjusted on the bolster of the roadway .
  • Three flip-flops, each equipped with a probe cooperating with these snails, make it possible to determine the stroke of the parts of the hours, quarters and minutes and to adjust the number of blows sounded.
  • timepieces have mechanisms that make it possible to display, in addition to the time of the carrier's place of residence (also called HT for Home Time), the time of a second time zone (also called GMT for Greenwich Meridian Time, also called Local Time).
  • HT time of the carrier's place of residence
  • GMT Greenwich Meridian Time
  • the present invention aims to provide a minute repeater mechanism for ringing both the local time and the time of a second time zone, while obtaining a mechanism whose thickness is reasonable, by setting in common of a number of elements.
  • the invention relates to a mechanical timepiece comprising a mechanism for indicating the time of a first and a second time zone, provided with a striking device for producing, as desired , a bell corresponding to the time of the first or second time zone.
  • the ringing device is supplied with energy by a single controlled ringing barrel, to supply energy to the ringing device, by control means intended to trigger a ringing corresponding to the time of the first and the second time zone.
  • the ringer barrel is loaded independently or not the operation of the ringer.
  • control members comprise a first and a second control lever, respectively intended to trigger a ring corresponding to the time of the first and second time zones.
  • the barrel is charged by means of a single rack whose control levers are independent.
  • the movement includes a display mechanism of a first and a second time zone, that is, it includes a first wheel hours relating to HT time driven by a conventional timer train and a second hour wheel relative to GMT, also driven by the timer train and provided with independent correction means.
  • the striking mechanism essentially comprises a system of snails, comprising a minute snail 10, a quarter snail 12 mounted coaxially on the minute snail 10.
  • the skilled person may also recognize in the drawing, a surprise device, not essential to the invention and which will not be described in detail.
  • both the minute and quarter ringing parts and the driving elements of the bell, the rack pinion (not visible in the drawing), the ringing barrel 15 (visible on the figure 2 ) are of conventional type.
  • the device further comprises a first and a second hammer 14 and 16 driven by lifts 18 actuated by the ringing parts.
  • the hammers strike stamps wrapped around the movement.
  • the first hammer 14 is intended, as will be understood below, to ring HT hours and quarters.
  • the second hammer 16 intended to strike one of the notes of the quarter ring and the note of the minute ring, is of conventional type.
  • a third hammer 17, visible on the Figures 3 to 5 lets ring the GMT hours on a third stamp.
  • the two hammers hours 14 and 17 are located in two different planes and are substantially superimposed.
  • the elements intended for the ringing of hours HT and GMT are particular.
  • the mechanism includes two hours snails, a first 100 and a second 200 respectively for providing information relating to the hour HT and GMT.
  • the hourglass HT 100 hours is disposed coaxially with a star with twelve teeth 102, driven one step per hour via a pin 22 that carries the quarter snail 12.
  • the time setting HT by means of the winding stem causes the rotation of the roadway and therefore that of the quarters snail.
  • the pin 22 therefore causes, if the amplitude of the adjustment If required, the star 102 and suitably positions the hourglass HT 100.
  • the snail of GMT hours 200 is disposed coaxially with a star with twelve teeth 202, driven one step per hour via a finger 204, itself driven at a rate of one revolution per hour by the gear of the GMT system.
  • the finger 204 performs one turn per corrected hour and the snail of the hours 200 therefore advances by one step. Its position therefore remains consistent with the indication of the GMT time, without disturbing the hour HT.
  • the gearing of the GMT system is driven by the hour timer mechanism HT, it is easy to understand that the GMT time is also corrected when setting the time of the hour HT by means of the winder.
  • the time trigger mechanism HT is comparable to a conventional minute repetition mechanism. As detailed figure 2 it comprises a winding lever 104 pivotally mounted on the plate about an axis BB and operable by the user in a first direction from the outside of the watch case via a lock. This lever 104 carries a probe 106, intended to cooperate with the snail hours HT 100 to take information relating to time HT and define the travel of the lever 104.
  • a rack 108 provided with a circular sector gear 108a is pivotally mounted about the axis BB, on the lever 104.
  • the latter has an extra thickness 104a located in the plane of the rack 108 and arranged so as to push this last to rotate it around the BB axis.
  • the toothed sector 108a of the rack cooperates, via a rack pinion, with the ringer barrel 15, visible on the figure 1 , to charge it and provide the driving force needed to ring.
  • the ringer barrel is loaded when the ringer sounds.
  • a pin 110 is driven on the probe hours 106. It passes freely through the rack 108 and cooperates with a finger 111 pivotally mounted on the lever 104.
  • the finger 111 acts on a rocker 112 called "all-or-nothing" pivotally mounted on the turntable.
  • the toggle has the function of preventing quarter and minute rings from falling on their respective snail before the barrel is sufficiently armed to allow a ringing. complete.
  • the flip-flop 112 releases, in a conventional manner, the quarter and minute ringing parts to enable their actuation.
  • Flip-flop 112 is provided with a spring 114 intended to rest on a flange of the plate to ensure the positioning of flip-flop 112 against finger 111.
  • a ratchet of hours 116 is disposed coaxially with the rack pinion.
  • Ratchet 116 has, over a portion of its circumference, twelve pointed teeth intended to cooperate with the lifting of hours 18 which pivots freely on its axis. This lifting activates the hour hammer HT 14 which rings on the hour stamp HT.
  • the triggering mechanism of the GMT bell is particularly represented in the figure 3 . It comprises a second winding lever 204, pivotally mounted in a DC axis and operable by the user from outside the watch box via a second lock. In the example described here, this second lever is located at about 120 ° relative to the first lever 104 and is operable in the opposite direction to the first lever.
  • This lever 204 comprises, at its end located in the movement, a finger 204a which takes place in an oblong opening in a rocker 208.
  • This rocker 208 is mounted pivoting around the BB axis on the plate. It carries a probe 206, intended to cooperate with the snail hours GMT 200 to take a GMT time information and define the travel of the lever 204.
  • the actuation of the lever 204 causes rotation of the rocker 208 concentrically to the rack 108, via the finger 204a which pushes it while sliding in the oblong opening, and the pivoting of the feeler 206 which comes to bear on the cochlea GMT 200 hours.
  • a pin 216 is fixed on the rack 108 and is arranged to cooperate with the rocker 208 so that the movement of the rocker under the action of the lever 204, rotates the rack about the axis BB, in the same direction than when it is actuated by the first lever 104.
  • the rack 108 to load the ringer barrel to provide the driving force necessary for the ringing.
  • the flip-flop 208 terminates in a hook 208a whose role will appear below.
  • the second lever 204 is independent of the rack 108 and not fixed thereto. In this way, the actuation of the rack by one of the levers does not cause the movement of the other lever. Only the probe that must take the information on the chosen time zone moves and the rack performs well a race adapted to the time to ring.
  • the flip-flop 208 cooperates with a second toggle flip-flop 212 disposed above and parallel to the flip-flop 112 of the ringer HT. These two elements are connected by a pillar 214.
  • a pin 210 is driven on the probe hours 206. It passes freely through the rocker 208 and cooperates with a finger 211 pivotally mounted on the rocker 208, which acts on the latch 212.
  • the flip-flop 212 solidly drives the flip-flop 112 which releases the ringer parts of the quarters and minutes, common with the hour ringer. HT, to enable their activation.
  • an intermediate cam GMT 219 is mounted to rotate coaxially with the lifting hours 18 with which it is secured by a pin 217 connecting one and the other of these parts. Room 219 operates the GMT 17 hammer that strikes the GMT hour stamp.
  • the mechanism includes, particularly to the invention a selector stamps 22 described in detail below.
  • each hammer is provided with a pin cooperating with a spring which makes it fall when it has been lifted by its lifting, and with a counter-spring, which acts in opposite directions so that the hammer do not stay in touch with the stamp and it may ring.
  • the distance of the hammers from the stamp is regulated by a cone-shaped stop against which the counter-springs rest. Generally, this stop is screwed into the plate.
  • the counter-springs are based on different levels of the conical portion. Their position is thus defined and also the rest position of the hammers.
  • the hour hammers HT 14 and GMT hours 17 are also each provided with a stop 130 and 230. These are superimposed and each consist of an arm movable about the same axis DD which is orthogonal to them. They are held in abutment against a set screw 132 and 232 by a spring 134 and 234 respectively. Each abutment cooperates, at a first of its ends 130a and 230a, with a pin 136 and 236 disposed on the hour hammer HT 14 and GMT hours 17 and, at its second end 130b and 230b, with the stamp selector 22 mentioned above.
  • the selector 22 comprises an axis provided with a first cam 138, intended to cooperate with the stop 130 of the hour hammer HT and a second cam 238, intended to cooperate with the stop 230 of the hammer hours GMT.
  • the cams 138 and 238 are arranged on the stamp selector 22 so that they are together in their first and second positions, respectively defining first and second positions of the stamp selector.
  • the selector 22 when the selector 22 is in its first position, only the hour hammer HT 14 can hit its stamp, the hammer hours GMT 17 is blocked by its stop 230.
  • the selector 22 when the selector 22 is in its second position, only the hammer hours GMT 17 can hit his stamp, the hour hammer HT 14 being blocked by its stop 130.
  • the spring 234 of the abutment hours GMT is more powerful than the 134 of the abutment hours HT. Due to the shape of the first circular sector 238b, it exerts a return torque on the stamp selector 22 which, at rest, keeps the latter in its first position.
  • the hook 208a of the rocker cooperates with the notch 238a of the cam 238.
  • the rocker 208 Once the rocker 208 has brought the selector into its second position, it is thus maintained by bearing against the rocker 208 under the effect of the spring GMT 234. Then, when it has completed its entire actuation path, it returns to its initial position simultaneously to the rack 108 and, when is no longer in contact with the stamp selector 22, it returns to the first position under the effect of the spring 234 of the abutment 230 hours GMT.
  • the carrier In operation, when the carrier actuates the lever 104 to have a time information HT, it drives the rack 108.
  • the stamp selector 22 is in its first position, the GMT time stamp is not active. The hour, the quarters and the minutes are then sounded in a manner similar to a repetition with minutes of classic type on the stamp of hours HT and on minutes.
  • the carrier When the carrier activates the lever 204 to have information on the GMT time, it drives the rocker 208 and the rack, without the lever 104 does not move.
  • the movement of the rocker brings the selector of stamps in its second position, the hour stamp HT then being inactive.
  • the time is then sounded on the GMT hour stamp, the quarter notes on the minute stamp and, as explained above, either on the GMT hour stamp or the HT hour stamp, and the minutes on the minute stamp. .
  • each lever can act on a rack, each cooperating with a rack pinion whose teeth embrace the two racks. Again, the levers are independent of their rack so that only one of the two probes is active at a time.
  • the two levers 104, 204 are actuated in the same direction. They are offset and can each act on a rack 308 and 408 which they are independent. Each rack directly actuates the rack pinion 50 and each lever carries a probe 106, 206 which will take its information on its respective snail, the snails of hours HT 100 and GMT 200 being, in this case, not necessarily superimposed.
  • a bolt 51 positioned on the outside of the watch case makes it possible to select which of the two hours must be sounded.
  • This result can be obtained, for example, by the schematic mechanism on the figure 7 .
  • the two levers 104, 204 are superimposed.
  • the lock acts on one or other of the levers via a cam 52 movable in the direction of the thickness of the movement.
  • the cam 52 comprises a worm 54 driven by the selection bolt 51.
  • the actuation of the bolt 51 causes the displacement of the screw 54 and the cam 52 in the direction of the thickness of the movement, that is, that is to say that the cam is, in a first position of the bolt 51, at the level of the first lever 104 and, in a second position of the bolt 51, at the level of the second lever 204.
  • the lock therefore only causes only one of the two levers which, like the one explained above, triggers the chosen ring.
  • the selection bolt can also act directly on the probe.
  • the latter is double is comprises pivotally mounted at its end, a rocker with two points located at two different levels, each being capable of cooperating, respectively, with the snails HT hours and hours GMT, the latter being superimposed.
  • a jumper positions the rocker on which acts the bolt.
  • a selection bolt 51 allows the wearer to select which of the two hours must be sounded.
  • the bolt acts on a rocker 56 which carries, in a staggered manner, the two snails HT 100 and GMT 200 hours.
  • the two snails HT 100 and GMT 200 hours.
  • one or other of the snails is positioned in the race of the feeler of the hours 106.
  • the stars of the hours carrying the snail are trained on two different levels.
  • stamp selector does not act on the stops of the hammers, but on mutes that smother the stamp that should not not ring. In this case, it is understandable that the two hammers strike their stamp, but only the one that is in function produces a clear sound.
  • the mechanism can be adapted to any type of ring, quarter or big ring.
  • the ringer barrel is loaded independently of the operation of the ringer, that is to say that the ringer barrel is not loaded at the time of the ringing.
  • the principle of operation of a great ring is given in the book "The Complicated Watches" already cited. From a conventional system, the skilled person may, for example, adapt a selection bolt as proposed to the figure 8 , so that when the bell is triggered (bypass or manually), the snail of the selected hours cooperates with the hour sensor.
  • the device may not include a stamp selector.
  • the mechanism comprises only two stamps and two hammers by means of which hours HT and GMT are sounded. It is the wearer who knows, depending on the lever it operates, whether it sounds the hour HT or GMT.
