Abstract

The basic mechanism used consists of a driving tooth (8), units pinion/indicator (3), tens pinion/indicator (4), return pinion (10) and auxiliary pinion (12). To this is added an annual pinion (18) which selectively engages with the driving tooth only when passing from 30 to01 and with the tens pinion only when the latter is passing from 2 to 3 and from 3 to 0.

Description

La présente invention se rapporte à un procédé pour former un quantième actionné par un mouvement d'horlogerie pour faire apparaítre successivement et automatiquement tous les quantièmes du 01.03 d'une année au 28 ou 29.02 de l'année suivante, ainsi qu'à un mécanisme pour la mise en oeuvre de ce procédé.The present invention relates to a method for form a calendar powered by a watch movement to bring up successively and automatically all the dates from 01.03 of a year to 28 or 29.02 of the year next, as well as a mechanism for implementation of this process.

Les mécanismes de quantièmes pour pièces d'horlogerie peuvent être classés en deux types en ce qui concerne l'affichage, ceux qui comportent une graduation portant successivement les chiffres des trente et un quantièmes des mois les plus longs, et ceux qui portent sur deux mobiles d'affichage distincts, les chiffres des dizaines et ceux des unités. Ce second type d'affichage est généralement utilisé pour permettre d'afficher des chiffres plus grands que lorsque l'on a trente et un quantièmes sur un même mobile d'affichage, la hauteur de ceux-ci étant forcément limitée par un angle correspondant à 1/31ème de la longueur de la circonférence sur laquelle les quantièmes sont disposés.The date mechanisms for timepieces can be classified into two types with regard to the display, those which include a graduation bearing successively the digits of the thirty-one calendar of the longest months, and those which relate to two mobiles. separate display, tens and unit digits. This second type of display is generally used to allow larger figures to be displayed than when there are thirty-one dates on the same display mobile, the height of these being necessarily limited by an angle corresponding to 1/31 th of the length of the circumference on which the dates are arranged.

Il existe différents types de mécanismes plus ou moins compliqués utilisés en liaison avec le second type d'affichage. Un des problèmes rencontrés avec le type à deux mobiles d'affichage est celui de la correction de la date en fin de mois.There are different types of mechanisms more or less complicated used in connection with the second type of display. One of the problems encountered with the type with two mobiles display is that of the date correction at the end of months.

Parmi les solutions proposées pour tenter de résoudre ce problème, on peut citer par exemple le CH 689601, se rapportant à une solution qui, pour éviter une longue correction propose de placer sur le disque des unités deux fois de suite le chiffre "1" en fin de mois, en sorte que le premier "1" est associé au "3" du disque des dizaines et le second "1" est associé au "0" du disque des dizaines. De ce fait, la correction entre le "30" et le "1" ne nécessite que d'entraíner le mécanisme de quantième d'un pas supplémentaire. Par contre le disque des unités doit porter trois séries de dix chiffres plus le "1" supplémentaire, diminuant fortement la grandeur maximum des chiffres, en sorte que l'avantages de l'affichage à deux mobiles distincts est considérablement réduit.Among the solutions proposed to try to solve this problem, we can quote for example the CH 689601, relating to a solution which, to avoid a long correction offers to place units on the disk twice immediately the number "1" at the end of the month, so that the first "1" is associated with "3" on the tens disc and the second "1" is associated with "0" on the tens disc. From this done, the correction between "30" and "1" only requires to drive the date mechanism by an additional step. On the other hand the disc of the units must carry three series ten digits plus the additional "1", greatly decreasing the maximum size of the figures, so that the advantages the display on two separate mobiles is considerably reduced.

Une autre solution a été proposée dans le CH 310559, dans lequel le mécanisme de quantième comporte une roue de trente et une dents entraínée d'un pas par jour et solidaire d'une roue de trente dents plus un espace correspondant à la trente et unième dent. Cette roue engrène avec un pignon de dix dents portant les chiffres des unités, de sorte qu'à chaque tour de la roue de trente et une dents, l'espace libre vient en regard du pignon des unités qui reste stationnaire, permettant ainsi, à chaque fin de mois, d'afficher le chiffre "1" deux jours de suite.Another solution has been proposed in CH 310559, in which the date mechanism includes a thirty-one teeth driven one step a day and united of a wheel of thirty teeth plus a space corresponding to the thirty-first tooth. This wheel meshes with a pinion of ten teeth bearing the unit numbers, so that at each revolution of the wheel of thirty-one teeth, free space comes opposite the pinion of the units which remains stationary, allowing, at the end of each month, to display the number "1" two days in a row.

Le principal inconvénient de ce mécanisme réside dans le fait qu'il permet d'avoir soit les deux disques des unités et des dizaines côte à côte, soit de les avoir superposés. Dans le premier cas, il faut deux guichets pour dissimuler l'espace formé entre les bords des disques, dans le second cas, les deux chiffres du quantièmes se trouvent à deux niveaux différents ce qui n'est pas beau et gêne la lecture.The main drawback of this mechanism is the fact that it allows to have either the two disks of units and dozens side by side, or having them superimposed. In the first case, you need two windows to hide the space formed between the edges of the discs, in the second case, the two digits of the date are at two different levels which is not beautiful and hinders the reading.

On a pu remédier à cet inconvénient dans le CH 688671, en transposant le mécanisme à trente dents et un espace à la place de la trente et unième dent à un affichage à deux disques concentriques. La roue d'entraínement de trente et une dent de ce mécanisme occupe toutefois une très grande surface. Le JP 51-34748 se rapporte à un mécanisme de quantième à deux mobiles d'affichage pour les unités et les dizaines qui est actionné par un système de cames et de leviers permettant de faire alterner sans aucune correction les mois de 30 jours et les mois de 31 jours. Un tel mécanisme présente cependant un inconvénient majeur puisque deux mois de 31 jours se succèdent chaque année, en sorte qu'il manquera un jour en août et un jour en janvier. Or étant donné que le cycle normal de ce mécanisme est de 61 jours, (un mois de 30 jours plus un mois de 31 jours) il faudra deux fois par année effectuer une correction de 31 pas pour retrouver le "31" manquant à fin janvier et à fin août. Dans ces conditions il est sans doute préférable d'effectuer cinq corrections d'un quantième (voire de deux ou trois quantièmes à fin février) par année que de n'avoir que trois corrections comme dans le mécanisme susmentionné, mais dont deux sont chacune de 31 quantièmes.We could remedy this drawback in CH 688671, by transposing the mechanism to thirty teeth and a space at the place the thirty-first tooth in a two-disc display concentric. The thirty-one drive wheel tooth of this mechanism however occupies a very large area. JP 51-34748 relates to a date mechanism at two display mobiles for the units and the tens which is operated by a system of cams and levers allowing to alternate without correction the months of 30 31 days and months. Such a mechanism presents however a major drawback since two months of 31 days follow each other each year, so that a day in August and day in January. Since the normal cycle of this mechanism is 61 days, (a month of 30 days plus a month of 31 days) it will take twice a year make a correction of 31 steps to find the "31" missing at the end of January and at the end of August. In these conditions it is probably best to make five corrections a calendar (or even two or three calendar to end of February) per year than having only three corrections as in the aforementioned mechanism, but two of which are each of 31 calendars.

Bien d'autres mécanismes associés à des organes d'affichage distincts pour les chiffres des unités et ceux des dizaines existent. Par contre aucune de ces solutions n'a mis en évidence un avantage potentiel que comporte un tel mode d'affichage pour permettre de réaliser de manière simple un quantième annuel dans lequel une seule correction par année est nécessaire.Many other mechanisms associated with display devices separate for unit and unit figures dozens exist. However, none of these solutions has highlighted a potential benefit of such a display mode to allow simple realization an annual calendar in which only one correction per year is required.

Le but de la présente invention est d'apporter une solution permettant de réaliser un quantième annuel simple et fiable.The purpose of the present invention is to provide a solution for making a simple annual calendar and reliable.

A cet effet, la présente invention a tout d'abord pour objet un procédé pour former un quantième actionné par un mouvement d'horlogerie pour faire apparaítre successivement et automatiquement tous les quantièmes du 01.03 d'une année au 28 ou 29.02 de l'année suivante selon la revendication 1. Elle a également pour objet un mécanisme de quantième pour la mise en oeuvre de ce procédé selon la revendication 2.To this end, the present invention has first of all for object a process for forming a date activated by a clockwork movement to successively appear and automatically all the dates of 01.03 of a year on 28 or 29.02 of the following year according to claim 1. It also relates to a date mechanism for the implementation of this method according to claim 2.

L'avantage essentiel de ce procédé réside dans le fait qu'en disposant les chiffres des unités et ceux des dizaines sur deux mobiles d'affichage distincts, il devient dès lors possible d'afficher successivement et automatiquement, donc sans aucune correction, tous les quantièmes du 01.03 au 28 ou 29.02 de l'année suivante en ne déplaçant sélectivement les mobiles d'affichage des unités et des dizaines que d'un seul pas par jour.The main advantage of this process is that that by arranging the numbers of the units and those of the tens on two separate display mobiles, it therefore becomes possible to display successively and automatically, so without any correction, all dates from 01.03 to 28 or 29.02 of the following year by not moving selectively the mobile display units and tens that one single step a day.

Grâce à cette particularité de ce procédé, on peut transformer un mécanisme de quantième classique nécessitant cinq corrections annuelles en un mécanisme de quantième annuel n'en demandant plus qu'une, par l'adjonction d'une seule roue annuelle. Ce mécanisme ne comporte ni bascule ni came d'armage de ressort destiné à accumuler de l'énergie pour l'entraínement de disques de calendriers comme on le trouve fréquemment lorsque ce disque doit être avancé sélectivement de plus d'un pas lors du passage par exemple du "30" au "01" du mois suivant, dans le cas des mois de trente jours.Thanks to this particularity of this process, we can transform a classic date mechanism requiring five annual corrections into an annual calendar mechanism asking for only one, by adding only one annual wheel. This mechanism has neither toggle nor spring winding cam for accumulating energy for training calendar discs as we frequently finds when this disc needs to be selectively advanced more than one step when passing for example the "30" to "01" of the following month, in the case of the months of thirty days.

D'autres avantages apparaítront au cours de la description qui va suivre.

  • FIGS. 11 and 12 illustrate the positions of the mobiles of this same mechanism when the date changes from "30" to "01".

    • Le mécanisme de quantième illustré par la figure 1 comporte deux disques, un disque des unités 1 portant dix chiffres ou un multiple de dix destiné à l'affichage des unités, un disque des dizaines 2 portant quatre chiffres ou un multiple de quatre destiné à l'affichage des dizaines. Le chiffre "0" du disque des dizaines 2 peut être supprimé et remplacé par un espace vide. Les deux disques 1 et 2 sont concentriques et permettent l'affichage des chiffres des unités et des dizaines au travers d'un guichet 5 unique.The date mechanism illustrated in Figure 1 has two disks, one disk of units 1 carrying ten digits or a multiple of ten for displaying units, a tens 2 disc with four digits or a multiple of four for displaying tens. The digit "0" from the tens 2 disc can be deleted and replaced by an empty space. The two discs 1 and 2 are concentric and allow the display of the digits of units and tens through a single window 5.

    Le disque des unités 1 est solidaire d'une roue dentée des unités 3 qui présente 10 dents ou un multiple de dix. Le disque des dizaines 2 est solidaire d'un pignon des dizaines 4 (figure 2) qui présente quatre dents ou un multiple de quatre. Le pignon des dizaines 4 et la roue des unités 3 sont concentriques, le pignon 4 étant partiellement logé dans un dégagement circulaire formé au centre de la roue des unités 3. Les surfaces des deux disques 1, 2 portant les chiffres des quantièmes sont coplanaires, comme on peut s'en rendre compte sur la figure 6. The disc of the units 1 is secured to a toothed wheel 3 units which has 10 teeth or a multiple of ten. The tens 2 disc is attached to a tens pinion 4 (figure 2) which has four teeth or a multiple of four. Tens pinion 4 and unit wheel 3 are concentric, the pinion 4 being partially housed in a circular clearance formed in the center of the wheel units 3. The surfaces of the two discs 1, 2 carrying the date digits are coplanar, as we can imagine report on figure 6.

    La roue des unités 3 est reliée à la roue des heures du rouage indicateur de l'heure (non représenté) qui fait deux tours en 24 heures par une roue intermédiaire qui entraíne une roue de calendrier 7 à raison d'un tour en 24 heures. Cette roue de calendrier 7 porte un doigt de quantième 8 qui entraíne la roue des unités 3 d'un pas toutes les 24 heures.The unit wheel 3 is connected to the hour wheel of the cog hour indicator (not shown) which makes two turns in 24 hours by an intermediate wheel which drives a calendar wheel 7 at the rate of one revolution in 24 hours. This calendar wheel 7 carries a date finger 8 which drives the wheel of units 3 one step every 24 hours.

    Un renvoi 10 porté par un tenon 10a solidaire de la platine de la pièce d'horlogerie engrène avec le pignon des dizaines 4. Ce renvoi 10 se situe sur la trajectoire d'une goupille 9 portée par la roue des unités 3, en sorte que ce renvoi 10 est entraíné d'un pas à chaque tour de la roue des unités 3 et entraíne lui-même le pignon des dizaines 4 également d'un pas. L'entraínement du pignon des dizaines 4 coïncide avec le passage du disque des unités 1 de "9" à "0".A reference 10 carried by a tenon 10a secured to the plate of the timepiece meshes with the pinion of the tens 4. This reference 10 is located on the trajectory of a pin 9 carried by the wheel of the units 3, so that this reference 10 is driven one step at each turn of the wheel 3 units and also drives the tens gable 4 also one step. Tens 4 pinion drive coincides with the passage of the disc of units 1 from "9" to "0".

    Pour éviter de devoir effectuer une correction importante après le "31" en passant pas à pas par "32","33" ainsi de suite jusqu'à ce qu'on retombe sur "01", la roue des unités 3 porte un mobile auxiliaire constitué par un pignon de fin de mois 12 dont une dent est positionnée par une came 15 solidaire du pignon des dizaines 4 à la place d'une dent évidée 11 de la roue des unités 3. Chaque dent du pignon de fin de mois 12 est associée à un galet pivotant 14 en rubis. Ces galets 14 se situent à la hauteur de la came 15, de manière à ce que ces galets 14 roulent sur la came 15, réduisant ainsi le frottement à un minimum entre cette came 15 et le pignon de fin de mois 12.To avoid having to make a major correction after "31" passing step by step through "32", "33" as well immediately until we come back to "01", the wheel of 3 units carries an auxiliary mobile consisting of a pinion at the end of month 12, a tooth of which is positioned by a cam 15 secured to the tens pinion 4 instead of a tooth hollowed out 11 of the wheel of the units 3. Each tooth of the pinion of end of month 12 is associated with a pivoting roller 14 in ruby. These rollers 14 are located at the height of the cam 15, so that these rollers 14 roll on the cam 15, thus reducing friction to a minimum between this cam 15 and the end of month pinion 12.

    La came 15 présente un dégagement 15a situé entre deux dents du pignon des dizaines 4, correspondant au passage du chiffre "3" au chiffre "0" du disque des dizaines 2. Grâce à cette came 15 et à son dégagement 15a, le pignon de fin de mois est bloqué angulairement par rapport à la roue des unités 3 lors du changement de chiffres des dizaines tant qu'une portion de la came 15 coupe la trajectoire d'un galet 14, ce qui est le cas lors des changements de dizaines, sauf lors du changement du "31" au "01" qui correspond à l'évidement 15a de la came 15, de sorte que dans ce cas, le pignon de fin de mois 12 peut tourner d'un pas, la roue des unités 3 restant immobile. Par conséquent, le disque des dizaines passe du "3" au "0", alors que le disque des unités reste sur le chiffre "1" qui correspond au chiffre des unités des quantièmes "31" et "01".Cam 15 has a clearance 15a located between two teeth of the tens pinion 4, corresponding to the passage of the digit "3" to digit "0" on the tens 2 disc. this cam 15 and at its release 15a, the end gear of month is locked angularly with respect to the unit wheel 3 when changing tens digits both that a portion of the cam 15 intersects the path of a roller 14, which is the case when changing tens, except when changing from "31" to "01" which corresponds to the recess 15a of cam 15, so that in this case the pinion end of month 12 can turn one step, the unit wheel 3 remaining stationary. Therefore, the tens disk changes from "3" to "0", while the unit disc remains on the digit "1" which corresponds to the digit of the units of calendar "31" and "01".

    Deux sautoirs de positionnement 16 et 17 coopèrent respectivement avec la roue des unités 3 et avec le pignon des dizaines 4. Comme on peut le constater sur les figures, le sautoir 16 de la roue des unités 3, plus épais, est susceptible de développer un couple plus grand que le sautoir 17. Ceci permet de maintenir la roue des unités 3 immobile lors du passage du disque des dizaines du "3" au "0" entre le "31" et le "01".La figure 3 montre le mécanisme de quantième lorsque les disques des unités 1 et des dizaines 2 affichent "30", c'est-à-dire que la goupille 9 solidaire de la roue des unités 3 tournant dans le sens de la flèche située sur cette roue 3 vient de faire avancer le renvoi 10 ainsi que le pignon des dizaines 4 d'un pas dans le sens de leurs flèches respectives, pour passer de la position de la figure 2 à celle de la figure 3.Two positioning jumpers 16 and 17 cooperate respectively with the wheel of the units 3 and with the pinion of the tens 4. As can be seen in the figures, the jumper 16 of the wheel of units 3, thicker, is likely to develop a greater torque than the long necklace 17. This keeps the wheel of the units 3 stationary during the transition from the tens disc from "3" to "0" between the "31" and the "01". Figure 3 shows the date mechanism when the drives of units 1 and tens 2 display "30", that is to say that the pin 9 secured to the wheel 3 units rotating in the direction of the arrow on this wheel 3 has just advanced the reference 10 as well as the gable of the tens 4 of a step in the direction of their respective arrows, to move from the position of the figure 2 to that of FIG. 3.

    La figure 4 montre la position des mobiles du mécanisme de quantième lorsque les deux disques 1, 2 affichent "31". On remarque que dans cette position, un galet 14a du pignon de fin de mois 12 se trouve en face du dégagement 15a de la came 15. Ainsi lors du passage de la position de la figure 4 à celle de la figure 5, le doigt de quantième 8 peut alors faire tourner le pignon de fin de mois 12 d'un pas. Celui-ci n'étant plus bloqué par la came 15, la roue des unités 3 reste alors immobile. Grâce à ce pignon de fin de mois et à la came 15, on peut directement faire passer le quantième du "31" au "01".Figure 4 shows the position of the moving parts of the mechanism date when the two discs 1, 2 display "31". Note that in this position, a roller 14a of the pinion at the end of month 12 is in front of clearance 15a of the cam 15. Thus when passing from the position of FIG. 4 to that of FIG. 5, the date finger 8 can then rotate the end of month pinion 12 by one step. This one no longer blocked by cam 15, the unit wheel 3 then remains motionless. Thanks to this end of month gear and cam 15, we can directly pass the date of the "31" to "01".

    Comme on peut le constater, alors que jusqu'ici, les mécanismes de quantièmes dans lesquels les unités et les dizaines sont affichés par deux disques séparés ont pour but essentiel, voire unique, la possibilité d'agrandir les chiffres des quantièmes, la présente invention montre qu'il est possible de tirer un autre profit de ce type de mécanisme pour réduire les corrections. En effet, on peut remarquer de la description qui précède que ce système d'affichage permet de passer du "31" au "01" sans faire bouger le disque des unités mais uniquement celui des dizaines.As can be seen, while so far the date mechanisms in which the units and tens are displayed by two separate discs intended essential, even unique, the possibility of enlarging the figures the present invention shows that it is possible to take further advantage of this type of mechanism to reduce corrections. Indeed, we can notice the foregoing description that this display system allows to go from "31" to "01" without moving the disc of units but only that of the tens.

    Les figures 7 à 11 montrent comment on peut tirer profit de cette particularité du mécanisme de quantième décrit jusqu'ici pour obtenir un quantième annuel basé sur un concept nouveau selon lequel l'affichage des quantièmes change entièrement automatiquement du 01.03 au 28 ou 29.02 de l'année suivante, sans que jamais l'un ou l'autre des disques ou les deux disques simultanément ne se déplacent de plus d'un pas par 24 heures. Comme on l'a vu précédemment, le mécanisme de base décrit précédemment permet déjà d'effectuer le passage du "31" au "01" en ne changeant que le disque des dizaines d'un pas et en maintenant le disque des unités 1 immobile. Il suffit alors de trouver un moyen pour déplacer simultanément les deux disques d'un pas pour passer du "30" au "01" et nous avons alors un quantième annuel très simple, capable de mettre en oeuvre ce procédé astucieux de changement de date présentant tous les avantages énumérés précédemment.Figures 7-11 show how you can shoot take advantage of this peculiarity of the date mechanism described so far to get an annual calendar based on a new concept according to which the date display changes fully automatically from 01.03 to 28 or 29.02 of the following year, without any of the disks or both disks simultaneously move from more than one step per 24 hours. As we saw earlier, the basic mechanism described above already allows to perform the passage from "31" to "01" by changing only the disk of tens of steps and holding the disk of 1 stationary units. You just have to find a way to simultaneously move the two discs one step to move from "30" to "01" and we then have a very annual calendar simple, capable of implementing this clever process of date change with all listed benefits previously.

    Ce résultat est obtenu par un procédé qui consiste à former, outre la chaíne cinématique qui relie quotidiennement le mouvement d'horlogerie à la roue des unités 3 et, tous les dix pas de cette dernière, au pignon des dizaines 4, par la cheville 9 solidaire de cette roue des unités 3 et par le renvoi 10, une chaíne cinématique annuelle qui relie directement le mouvement d'horlogerie au pignon des dizaines 4 et est programmée pour entraíner ce dernier d'un pas en même temps que la roue des unités 3 pour passer du "30" au "01" à la fin des mois de trente joursThis result is obtained by a process which consists in train, in addition to the kinematic chain that connects daily the clockwork movement at the wheel of units 3 and, every ten steps from the latter, at the gable of tens 4, by the pin 9 secured to this wheel of the units 3 and by reference 10, an annual kinematic chain that connects directly the watch movement at the gable of tens 4 and is programmed to train the latter by one step same time as the wheel of units 3 to go from "30" to "01" at the end of the thirty-day months

    Ce mécanisme de quantième est identique au précédent, à la seule différence qu'il comporte une roue annuelle 18 supplémentaire, permettant de former la chaíne cinématique annuelle et que le doigt de quantième 8 porte un ergot 8a destiné à entraíner sélectivement la roue annuelle comme on l'expliquera par la suite.This date mechanism is identical to the previous one, the only difference is that it has an additional annual wheel 18, allowing to form the annual kinematic chain and that the date finger 8 carries a lug 8a intended to selectively drive the annual wheel as we will explain it later.

    La roue annuelle 18 comporte vingt-quatre dents, soit deux par mois. Certaines de ces dents sont amincies à l'extérieur d'un arc de cercle 18a concentrique à l'axe de cette roue annuelle 18, d'autres ne le sont pas. L'épaisseur des dents amincies de la roue annuelle 18 est donc réduite pour permettre à ces dents de passer sous l'ergot 8a du doigt de quantième. L'épaisseur des deux dents 4a du pignon des dizaines 4 correspondant au chiffre "0" s'étend sur toute l'épaisseur des dents de la roue annuelle 18, de sorte que l'on se trouve en position d'engrenage entre ces dents et le pignon des dizaines 4. Par contre l'épaisseur des autres dents de ce pignon des dizaines est réduite pour qu'elles ne rencontrent pas les dents de la roue annuelle 18.The annual wheel 18 has twenty-four teeth, i.e. two per month. Some of these teeth are thinned out an arc of a circle 18a concentric with the axis of this annual wheel 18, others are not. The thickness of thinned teeth of the annual wheel 18 is therefore reduced for allow these teeth to pass under the lug 8a of the finger of calendar. The thickness of the two teeth 4a of the tens pinion 4 corresponding to the digit "0" spans the entire the thickness of the teeth of the annual wheel 18, so that we are in gear position between these teeth and the pinion of tens 4. On the other hand the thickness of the others teeth of this tens gable is reduced so that they don't not meet the teeth of the annual wheel 18.

    Les dents de la roue annuelle 18 qui ne sont pas amincies sont au nombre de cinq et correspondent aux cinq mois de l'année ayant moins de 31 jours. Sur les figures relatives à ce quantième annuel, toutes les deux dents de la roue annuelle sont numérotées en fonction des mois de l'années auxquels elles correspondent, de 01 pour janvier à 12 pour décembre. Comme on peut le constater grâce à cette numérotation, les dents non amincies de la roue annuelle 18 correspondent donc aux mois de février, avril, juin, septembre et novembre.The teeth of the annual wheel 18 which are not thinned are five in number and correspond to five month of the year with less than 31 days. In the figures relating to this annual calendar, every two teeth of the annual wheel are numbered according to the months of the years to which they correspond, from 01 for January to 12 for December. As can be seen from this numbering, the unthinned teeth of the annual wheel 18 therefore correspond to the months of February, April, June, September and November.

    Pour comprendre comment fonctionne ce quantième annuel, nous décrirons tout d'abord ci-après, à l'aide des figures 7 à 10, le fonctionnement de ce mécanisme de quantième entre le 29.10 et le 01.11, c'est-à-dire le cas du passage de la fin d'un mois de 31 jours au 1er du mois suivant, puis nous décrirons à l'aide des figures 10 et 11, le fonctionnement de ce mécanisme de quantième entre le 30.11 et le 01.12, c'est-à-dire dans le cas du passage de la fin d'un mois de 30 jours au 1er du mois suivant.To understand how this annual calendar works, we will first describe below, with the help of Figures 7 to 10, the functioning of this calendar mechanism between 29.10 and 01.11, that is to say the case of the passage from the end of a month of 31 days to the 1 st of the following month, then we will describe with the help of Figures 10 and 11, the operation of this date mechanism between 30.11 and 01.12 is ie in the case of the passage from the end of a month of 30 days to the 1 st of the following month.

    Si nous observons la position des mobiles du mécanisme de quantième entre le 29.10 et le 30.10 (figures 7 et 8), nous voyons que le doigt de quantième 8 a entraíné la roue des unités 3 d'un pas et que celle-ci a entraíné à son tour le pignon des dizaines 4 à l'aide de la goupille 9. Etant donné que la dent du pignon des dizaines 4 qui engrène avec la roue annuelle 18 est la dent "0", qui est conformée pour venir en prise avec toutes les dents de la roue annuelle 18, la roue annuelle est entraínée d'un pas.If we observe the position of the moving parts of the mechanism date between 29.10 and 30.10 (Figures 7 and 8), we see that the date finger 8 has driven the wheel units 3 by one step and that this in turn resulted the tens pinion 4 using the pin 9. Being given that the tens pinion tooth 4 which meshes with the annual wheel 18 is the tooth "0", which is shaped for engaging all the teeth of the annual wheel 18, the annual wheel is driven one step.

    Pour passer du 30.10 au 31.10 (figures 8 et 9), le doigt de quantième 8 entraíne d'un pas la roue des unités 3. La roue annuelle 18 ne bouge pas la dent correspondant au mois "10" étant une dent amincie qui passe sous l'ergot 8a du doigt de quantième 8. On constate aussi que la prochaine dent de la roue des unités 3 qui viendra en prise avec le doigt de quantième est en réalité une dent du pignon de fin de mois 12. Or dans la position illustrée par la figure 9 et qui correspond au 31.10, on voit que lorsque le doigt de quantième 8 va entraíner la dent de ce pignon de fin de mois 12, celui-ci n'est plus empêché de tourner par la came 15, étant donné que le galet 14 qui vient normalement buter contre cette came 15 se trouve vis-à-vis d'un dégagement 15a de cette came.To go from 30.10 to 31.10 (Figures 8 and 9), the date finger 8 drives the unit wheel 3 by one step. The annual wheel 18 does not move the tooth corresponding to the month "10" being a thinned tooth which passes under the lug 8a of the date finger 8. We also note that the next tooth of the wheel of the units 3 which will engage with the date finger is actually a tooth of the end pinion of months 12. Now in the position illustrated by figure 9 and which corresponds to 31.10, we see that when the finger of date 8 will train the tooth of this end of month gear 12, the latter is no longer prevented from rotating by the cam 15, since the roller 14 which normally abuts against this cam 15 is opposite a clearance 15a of this cam.

    Le pignon de fin de mois 12 peut donc tourner sur lui-même sans entraíner la roue des unités 3, mais en entraínant pas contre le pignon des dizaines 4 d'un pas, la dent "0" de ce pignon 4 engagée dans la denture de la roue annuelle 18 entraínant de nouveau cette roue 18 d'un pas. Ainsi le quantième qui affichait précédemment "31" n'a changé que le chiffre des dizaines, celui des unités étant resté immobile et le quantième suivant est donc "01".The end of month pinion 12 can therefore turn on itself without driving the wheel of units 3, but by driving not against the tens pinion 4 of a step, tooth "0" of this pinion 4 engaged in the teeth of the annual wheel 18 again driving this wheel 18 a step. So the date that previously displayed "31" only changed the digit of tens, that of the units having remained motionless and the next calendar date is therefore "01".

    Nous allons maintenant nous référer aux figures 11 et 12 pour voir comment s'effectue le passage direct du "30" au "01" en supposant que la dent de la roue annuelle qui se trouve dans la trajectoire de l'ergot 8a est la dent "11" correspondant à la fin du mois de novembre. Il s'agit donc d'une des cinq dents de la roue annuelle avec laquelle l'ergot 8a est susceptible de venir en prise.We will now refer to Figures 11 and 12 to see how the direct passage from "30" to "01" assuming that the tooth of the annual wheel which is found in the trajectory of lug 8a is tooth "11" corresponding to the end of November. It is therefore of one of the five teeth of the annual wheel with which the lug 8a is likely to come into engagement.

    Lorsque le doigt de quantième 8 tourne à partir de la position illustrée à la figure 11 pour passer à celle illustrée par la figure 12, il entraíne d'un pas la roue des unités 3 alors que l'ergot 8a entraíne simultanément la roue annuelle 18 d'un pas également. Etant donné que la dent du pignon des dizaines 4 qui est engagée dans la denture de la roue annuelle correspond à une dent "0" conformée pour venir en prise avec toutes les dents de la roue annuelle 18, ce pignon des dizaines est donc entraíné d'un pas par la roue annuelle 18. Ainsi, le chiffre des unités qui était "0" passe à "1" et le chiffre des dizaines qui était "3" passe à "0".When the date finger 8 rotates from the position illustrated in figure 11 to move to that illustrated in Figure 12, it drives the unit wheel one step 3 while the lug 8a simultaneously drives the wheel annual 18 of a step also. Since the tooth of the gear of the tens 4 which is engaged in the teeth of the annual wheel corresponds to a tooth "0" shaped to come engaged with all the teeth of the annual wheel 18, this tens gear is therefore driven by one step by the wheel annual 18. So the unit figure which was "0" goes to "1" and the tens digit which was "3" goes to "0".

    Le mécanisme de quantième décrit ci-dessus permet donc de passer automatiquement et sans aucune correction du 01.03 au 28 ou 29.02 de l'année suivante.The date mechanism described above therefore allows to pass automatically and without any correction from 01.03 on 28 or 29.02 of the following year.
