La présente pièce d'horlogerie, dont seuls les organes nécessaires à la compréhension de l'invention ont été représentés, comprend un mouvement de montre ordinaire, dont le bâti ou cage est désigné par 1, ce mouvement servant à entraîner des organes indicateurs usuels du temps (heures, minutes et secondes), non représentés. Le rouage de ce mouvement comprend un arbre de petite seconde 2 (fig. 4), faisant un tour par minute, situé sur l'axe 6h-12h de la montre, qui déborde du bâti 1 du mouvement, et dont l'extrémité débordante porte normalement une aiguille de petite seconde qui a été supprimée.This timepiece, of which only the organs necessary for the understanding of the invention have been represented, comprises an ordinary watch movement, the frame or cage of which is designated by 1, this movement serving to drive the usual indicator organs of the time (hours, minutes and seconds), not shown. The cog of this movement includes a small second shaft 2 (fig. 4), making one revolution per minute, located on the 6 o'clock-12 o'clock axis of the watch, which projects beyond the frame 1 of the movement, and whose projecting end normally carries a small second hand that has been removed.

Le bâti 1 du mouvement ordinaire porte, montée sur sa face qui, normalement, serait munie du cadran de la montre, la cage, comprenant deux platines 3 et 4, d'un mécanisme auxiliaire, de chronographe, laquelle cage est munie d'un cadran 5. La platine 3 de ce mécanisme auxiliaire, située sous le cadran 5, porte le palier 6 d'un arbre 7, coaxial à l'arbre 2, portant une aiguille de seconde ou de chronographe 8. L'arbre 7 est soutenu, à son extrémité opposée, par un pont flexible 9 fixé à un élément, non représenté, de la cage du mécanisme de chronographe, qui exerce sur l'arbre 7 une pression axiale tendant à appliquer un coeur de remise à zéro 10 que porte cet arbre contre le palier 6 et, de ce fait, à créer sur l'arbre 7 une friction évitant tout ébat de l'aiguille 8.The frame 1 of the ordinary movement carries, mounted on its face which, normally, would be provided with the dial of the watch, the cage, comprising two plates 3 and 4, an auxiliary mechanism, chronograph, which cage is provided with a dial 5. The plate 3 of this auxiliary mechanism, located under the dial 5, carries the bearing 6 of a shaft 7, coaxial with the shaft 2, carrying a second or chronograph hand 8. The shaft 7 is supported , at its opposite end, by a flexible bridge 9 fixed to an element, not shown, of the cage of the chronograph mechanism, which exerts on the shaft 7 an axial pressure tending to apply a reset heart 10 that this shaft against the bearing 6 and, as a result, creating friction on the shaft 7 preventing any jerking of the needle 8.

L'arbre 7 porte, montée librement sur lui, une roue d'entraînement 11 rendue solidaire, mais à friction, du coeur 10 par une rondelle cambrée 12 interposée entre elle et ledit coeur.The shaft 7 carries, freely mounted on it, a drive wheel 11 made integral, but with friction, of the heart 10 by a cambered washer 12 interposed between it and said heart.

L'extrémité débordante de l'arbre 2 du rouage du mouvement de la montre usuelle 1 porte, en lieu et place de l'aiguille ordinaire de petite seconde, une roue 13, de même nombre de dents que la roue 11 dont elle est coaxiale.The projecting end of the shaft 2 of the gear train of the movement of the usual watch 1 carries, in place of the ordinary small seconds hand, a wheel 13, with the same number of teeth as the wheel 11 of which it is coaxial .

Le mécanisme de chronographe comprend une bascule 14, articulée en 15, qui porte un double pignon baladeur 16-17 dont les deux éléments, solidaires l'un de l'autre, sont situés chacun sur une des faces de ladite bascule. Ces deux pignons, de même nombre de dents, engrènent, lorsque la bascule 14 occupe sa position d'embrayage, représentée aux figs. 2 et 4, avec les deux roues 11 et 13, respectivement, ce qui les solidarise et assure ainsi l'entraînement de l'aiguille de chronographe 8.The chronograph mechanism comprises a lever 14, articulated at 15, which carries a double sliding gear 16-17, the two elements of which are integral with each other, are each located on one of the faces of said lever. These two pinions, of the same number of teeth, mesh, when the rocker 14 occupies its clutch position, shown in FIGS. 2 and 4, with the two wheels 11 and 13, respectively, which unites them and thus ensures the driving of the chronograph hand 8.

Il est à remarquer que les deux roues 11 et 13 pourraient avoir un nombre de dents différent, de même que les deux pignons baladeurs 16 et 17.It should be noted that the two wheels 11 and 13 could have a different number of teeth, as could the two sliding gears 16 and 17.

La bascule 14 est soumise à l'action d'un ressort de rappel 18 qui tend à la maintenir dans sa position d'embrayage. Elle est commandée par une roue à colonnes 19, réalisée sous forme d'une came à six nez, solidaire d'un rochet 20, à douze dents. Ce rochet est commandé par un cliquet 21 articulé en 22 sur une bascule de chronographe 23, articulée elle-même en 24, actionnée au moyen d'un poussoir 25. Le cliquet 21 se prolonge par une partie 21a, déformable élastiquement, prenant appui sur la tête d'un sautoir 26, articulé en 27, assurant la stabilité des différentes positions de la roue à colonnes. Ainsi, le ressort 21a est à triple fonction : d'une part il rappelle le cliquet 21, l'appliquant contre le rochet 20, d'autre part il rappelle le sautoir 26, l'appliquant également contre le rochet 20, et enfin il rappelle la bascule de chronographe 23 dans sa position de repos représentée au dessin.The lever 14 is subjected to the action of a return spring 18 which tends to keep it in its clutch position. It is controlled by a column wheel 19, produced in the form of a six-nose cam, integral with a ratchet 20, with twelve teeth. This ratchet is controlled by a pawl 21 articulated at 22 on a chronograph lever 23, itself articulated at 24, actuated by means of a pusher 25. The pawl 21 is extended by a part 21a, elastically deformable, bearing on the head of a jumper 26, articulated at 27, ensuring the stability of the different positions of the column wheel. Thus, the spring 21a has a triple function: on the one hand it recalls the pawl 21, applying it against the ratchet 20, on the other hand it recalls the jumper 26, also applying it against the ratchet 20, and finally it recalls the chronograph lever 23 in its rest position shown in the drawing.

La pièce d'horlogerie comprend en outre un organe indicateur des minutes (compteur de minutes) constitué par une aiguille 28 (fig. 5) montée sur un arbre 29 tournant entre les platines 3 et 4 de la cage du mécanisme de chronographe et qui est solidaire d'un coeur de remise à zéro 30. Une rondelle cambrée 31 est interposée entre le coeur 30 et la platine 3 afin de créer sur l'arbre 29 une friction empêchant tout ébat de l'aiguille 28. L'arbre 29 porte une roue 32 montée librement sur lui et qui est rendue solidaire, mais à friction, du coeur 30 par une rondelle cambrée 33 interposée entre ce dernier et ladite roue, ce qui permet que la remise à zéro de l'aiguille 28 puisse s'effectuer sans que la roue 32 soit entraînée. Cette roue est conduite, par l'intermédiaire d'un rouage comprenant deux mobiles 34 et 35 et un renvoi 36, par la roue 11 d'entraînement de l'aiguille de chronographe 8 qui engrène avec le renvoi 36.The timepiece further comprises a minute indicator (minute counter) constituted by a hand 28 (fig. 5) mounted on a shaft 29 rotating between the plates 3 and 4 of the cage of the chronograph mechanism and which is integral with a reset core 30. A cambered washer 31 is interposed between the core 30 and the plate 3 in order to create on the shaft 29 a friction preventing any flapping of the needle 28. The shaft 29 carries a wheel 32 freely mounted on it and which is made integral, but frictionally, with the heart 30 by a cambered washer 33 interposed between the latter and said wheel, which allows the resetting of needle 28 to be carried out without that the wheel 32 is driven. This wheel is driven, by means of a gear train comprising two mobiles 34 and 35 and a gear 36, by the wheel 11 for driving the chronograph hand 8 which meshes with the gear 36.

Il résulte de cet agencement que lorsque la roue 11 est entraînée, les pignons 16 et 17 étant engagés dans les roues 11 et 13 respectivement, l'aiguille 28 est entraînée également.It follows from this arrangement that when the wheel 11 is driven, the pinions 16 and 17 being engaged in the wheels 11 and 13 respectively, the needle 28 is also driven.

La remise à zéro des deux aiguilles 8 et 28 s'effectue à l'aide d'une bascule de remise à zéro 37, articulée en 38, présentant deux pannes 37a et 37b formant deux marteaux coopérant avec les coeurs de remise à zéro 10 et 30, respectivement. La bascule de remise à zéro 37 est soumise à l'action d'un ressort de rappel 39 qui tend à la faire tourner dans le sens contraire à celui des aiguilles d'une montre pour amener les deux marteaux à coopérer avec les deux coeurs de remise à zéro. Le retour de la bascule de remise à zéro 37 en position de repos, dans laquelle ses deux pannes 37a et 37b sont éloignées des deux coeurs 10 et 30, respectivement, s'effectue à l'aide de la bascule de chronographe 23 qui présente à cet effet un prolongement 23a coopérant avec un bras 37c que présente la bascule 37. Cette dernière présente en outre un bec 37d venant s'accrocher, lorsque la bascule est ramenée en position de repos par la bascule de chronographe 23, à une bascule de retenue 40 articulée en 41, soumise à l'action d'un ressort de rappel 42, et qui est actionnable à l'aide d'un poussoir de remise à zéro 43. Cette bascule présente, à son extrémité, une encoche 44 (fig. 1), dans laquelle vient se prendre le bec 37d de la bascule de remise à zéro 37.The reset of the two needles 8 and 28 is carried out using a reset lever 37, articulated at 38, having two purlins 37a and 37b forming two hammers cooperating with the reset hearts 10 and 30, respectively. The reset lever 37 is subjected to the action of a return spring 39 which tends to rotate it counterclockwise. to get the two hammers to cooperate with the two reset hearts. The return of the reset lever 37 to the rest position, in which its two purlins 37a and 37b are distant from the two hearts 10 and 30, respectively, is carried out using the chronograph lever 23 which presents this effect an extension 23a cooperating with an arm 37c presented by the rocker 37. The latter also has a spout 37d which hooks, when the rocker is returned to the rest position by the chronograph rocker 23, to a retaining rocker 40 articulated at 41, subjected to the action of a return spring 42, and which can be actuated using a reset push button 43. This rocker has, at its end, a notch 44 (fig. 1), in which the nozzle 37d of the reset lever 37 is caught.

Ce chronographe fonctionne de la façon suivante : lorsque le mécanisme occupe sa position d'arrêt, les aiguilles 8 et 28 étant à zéro et maintenues dans cette position par les deux marteaux 37a et 37b, respectivement, position représentée à la fig. 1, une pression exercée sur le poussoir 25 amène la roue à colonnes 19 dans la position représentée à la fig. 2 dans laquelle, sous l'action de son ressort de rappel 18, la bascule 14 a tourné dans le sens des aiguilles d'une montre, amenant le double pignon baladeur 16-17 qu'elle porte à engrener avec les deux roues coaxiales 11 et 13, respectivement, ce qui provoque l'entraînement des aiguilles 8 et 28.This chronograph operates as follows: when the mechanism occupies its stop position, the hands 8 and 28 being at zero and held in this position by the two hammers 37a and 37b, respectively, position shown in FIG. 1, a pressure exerted on the pusher 25 brings the column wheel 19 into the position shown in FIG. 2 in which, under the action of its return spring 18, the rocker 14 has rotated clockwise, causing the double sliding pinion 16-17 which it carries to mesh with the two coaxial wheels 11 and 13, respectively, which causes the hands 8 and 28 to be driven.

Simultanément, la partie terminale 23a de la bascule 23 agissant sur le bras 37c de la bascule de remise à zéro 37 a fait tourner celle-ci dans le sens des aiguilles d'une montre, à l'encontre de l'action de son ressort de rappel 39 libérant les deux coeurs 10 et 30. A fin de course de la bascule 37, son bec 37d s'est engagé dans l'encoche 44 de la bascule 40, en soulevant celle-ci légèrement à l'encontre de l'action de son ressort de rappel 42. Il en résulte que, dans cette position (fig. 2), les aiguilles 8 et 28 sont entraînées et que les marteaux 37a et 37b sont maintenus éloignés des coeurs de remise à zéro.Simultaneously, the end portion 23a of the lever 23 acting on the arm 37c of the reset lever 37 has turned the latter clockwise, against the action of its spring. recall 39 releasing the two hearts 10 and 30. At the end of the rocker 37 stroke, its beak 37d is engaged in the notch 44 of the rocker 40, lifting the latter slightly against the action of its return spring 42. It follows that, in this position (fig. 2), the needles 8 and 28 are driven and that the hammers 37a and 37b are kept away from the reset hearts.

Il est à remarquer que, si dans cette position du mécanisme une pression est exercée sur le poussoir de remise à zéro 43, cette fausse manoeuvre restera sans effet car, alors, un nez 40a que présente la bascule de retenue 40 viendra buter contre un bras 14a de la bascule 14, ce qui l'empêchera de se déplacer jusqu'à libérer la bascule de remise à zéro 37.It should be noted that, if in this position of the mechanism a pressure is exerted on the reset push-button 43, this false maneuver will have no effect because, then, a nose 40a presented by the retaining rocker 40 will abut against an arm 14a of the rocker 14, which will prevent it from moving until the reset rocker 37 is released.

Le chronographe étant en fonction, une pression exercée sur le poussoir 25 amène le déplacement d'un pas de la roue à colonnes 19, ce qui soulève la bascule 14, dégageant les pignons baladeurs 16-17 portés par elle des roues 11 et 13, débrayant ainsi le chronographe (fig. 3).The chronograph being in operation, a pressure exerted on the pusher 25 brings about the displacement of one step of the column wheel 19, which lifts the rocker 14, releasing the sliding gears 16-17 carried by it from the wheels 11 and 13, thus disengaging the chronograph (fig. 3).

A partir de cette position du mécanisme, l'utilisateur de la pièce peut soit remettre en marche le chronographe soit ramener les aiguilles 8 et 28 à zéro. Le chronographe est donc du type dit "à trois fonctions". Dans le premier cas il agit sur le poussoir 25, ramenant le mécanisme dans la position de la fig. 2, alors que, dans le deuxième cas, il agit sur le poussoir 43, déplaçant la bascule de retenue 40, dont les déplacements ne sont plus empêchés par le bras 14a de la bascule 14, ce qui libère le bec 37d de la bascule de remise à zéro 37 qui, sous l'action de son ressort de rappel 39, tombe,par un déplacement dans le sens contraire à celui des aiguilles d'une montre, sur les deux coeurs 10 et 30, remettant ainsi à zéro les aiguilles 8 et 28.From this position of the mechanism, the user of the piece can either restart the chronograph or reduce the hands 8 and 28 to zero. The chronograph is therefore of the so-called "three-function" type. In the first case it acts on the pusher 25, bringing the mechanism back to the position of FIG. 2, while, in the second case, it acts on the pusher 43, displacing the retaining lever 40, whose movements are no longer prevented by the arm 14a of the lever 14, which releases the spout 37d of the lever resetting to zero 37 which, under the action of its return spring 39, falls, by a movement in the opposite direction to that of clockwise, on the two hearts 10 and 30, thus resetting the hands 8 and 28.

En variante, l'arbre 7 portant l'aiguille de chronographe 8 pourrait être creux et l'arbre 2 du mouvement d'horlogerie, portant la roue 13, pourrait se prolonger à travers cet arbre creux et porter une aiguille de secondes trotteuse tournant au-dessus de l'aiguille 8.As a variant, the shaft 7 carrying the chronograph hand 8 could be hollow and the shaft 2 of the clock movement, carrying the wheel 13, could extend through this hollow shaft and carry a second seconds hand turning at - above needle 8.

Il est à remarquer, en se référant en particulier à la fig. 4, que la présente invention permet de transformer aisément une montre ordinaire, telle la montre dont le mouvement a été désigné par 1, qui ne comprend que des organes indicateurs usuels du temps (heures, minutes, éventuellement secondes) en une montre à chronographe, c'est-à-dire une montre comprenant des indicateurs dont la marche peut être interrompue et rétablie à volonté.It should be noted, with particular reference to fig. 4, that the present invention makes it possible to easily transform an ordinary watch, such as the watch the movement of which has been designated by 1, which comprises only the usual time indicating bodies (hours, minutes, possibly seconds) into a chronograph watch, that is to say, a watch comprising indicators whose operation can be interrupted and restored at will.

A cet effet, on supprimera le cadran ordinaire de la montre 1 et l'on placera sur le mouvement de celle-ci, à l'emplacement du cadran, le bâti du mécanisme auxiliaire comprenant les deux platines 3 et 4. Dans le cas où l'arbre 2 du rouage du mouvement 1 porte, à l'origine, une aiguille, par exemple une aiguille de petite seconde située hors du centre, on supprimera cette aiguille et on la remplacera par la roue 13. Bien entendu, les organes ordinaires de la montre portant les aiguilles d'heures, de minutes et de secondes au centre devront être prolongés de manière à s'étendre au-delà du cadran 5 porté par le mécanisme auxiliaire. Si l'arbre du rouage du mouvement 1 utilisé comme organe de prise de force pour l'entraînement des organes indicateurs supplémentaire, débrayables, ne porte pas d'aiguille, il devra lui aussi être prolongé afin de faire saillie au-delà du bâti du mouvement 1 pour permettre que la roue 13 soit située, en hauteur, dans l'épaisseur du mécanisme auxiliaire.To this end, the ordinary dial of watch 1 will be eliminated and the movement of the auxiliary mechanism comprising the two plates 3 and 4 will be placed on the movement of the latter, at the location of the dial. the shaft 2 of the gear train of the movement 1 carries, originally, a needle, for example a small second hand located outside the center, this needle will be removed and it will be replaced by the wheel 13. Of course, ordinary organs of the watch carrying the hour, minute and second hands in the center must be extended so as to extend beyond the dial 5 carried by the auxiliary mechanism. If the cog shaft of movement 1 used as a PTO for driving the additional disengageable indicator members does not carry a needle, it too must be extended in order to project beyond the frame of the movement 1 to allow the wheel 13 to be located, in height, in the thickness of the auxiliary mechanism.
