Description
Mécanisme indicateur des quantièmes pour montre-calendrier L'objet de la présente invention est un mé canisme indicateur des quantièmes pour mon tre-calendrier, comprenant une roue intermé diaire effectuant deux tours par jour et dont toutes les dents sont tronquées sauf une, cette dernière agissant sur une couronne dentée à vingt dents portant les chiffres des unités des quantièmes, chacun répété deux fois de suite, cette couronne comportant des moyens qui, lors du passage du deuxième zéro au pre mier un des unités, entraîne d'un pas une étoile portant les chiffres des dizaines des quantièmes.
L'unique figure du dessin représente une forme d'exécution de l'objet de l'invention don née à titre d'exemple.
Au centre du mécanisme représenté se trouve la roue à canon 1 accomplissant deux tours par jour et entraînant une roue intermé diaire 2 de même nombre de dents, qui ac complit par conséquent également deux tours par jour.
Toutes les dents 3 de cette roue sont tron quées, à l'exception d'une dent 4, qui est par conséquent plus longue que les autres.
Deux fois par jour cette dent agit sur une dent d'une couronne 5 présentant vingt dents 6 et portant les chiffres des unités des quantiè mes, soit de zéro à neuf , tous répétés deux fois de suite, comme on le voit en 7. Ainsi, un chiffre d'unité quelconque de quantième, apparu à minuit dans le guichet re présenté par le cadre 8 en traits mixtes, sera remplacé à midi au deuxième tour de la roue 2 par un second chiffre identique, qui ne dis paraîtra qu'au minuit suivant, pour faire alors place au chiffre qui lui fait suite.
Un sautoir 9, pivoté en 10, fixe les posi tions de la couronne dentée 5.
A l'intérieur de cette couronne se trouve une étoile à quatre branches 11, portant les chiffres des dizaines de quantièmes, soit de zéro à trois . Entre le dernier chiffre neuf porté par la couronne 5 et le premier zéro non représenté au: dessin en raison d'un arrachement partiel de la partie de la couronne portant lesdits chiffres, se trouve une dent supplémentaire 12, agissant sur l'étoile 11 à chacun de ses passages pour changer le chif fre des dizaines.
Un ressort 13 sert à la fois à presser le sautoir 9 contre la couronne et à immobiliser l'étoile entre deux changements de dizaines de quantièmes. Il est donc commun à ces deux organes et maintenu en place simplement par deux goupilles 14 du sautoir, entre lesquels il passe.
Ce mécanisme a l'avantage de permettre la construction d'un calibre très plat avec un très grand guichet. Il est avantageux d'y adjoindre un organe correcteur agissant sur la couronne des unités, ainsi que sur l'étoile des dizaines, pour pouvoir passer du vingt-huitième, vingt- neuvième, trentième, respectivement trente et unième jour d'une fin de mois au premier jour du mois suivant.
Date indicator mechanism for calendar watch The object of the present invention is a date indicator mechanism for my calendar, comprising an intermediate wheel performing two revolutions per day and all of the teeth of which are truncated except one, the latter. acting on a toothed crown with twenty teeth bearing the digits of the date units, each repeated twice in succession, this crown comprising means which, when passing from the second zero to the first one of the units, drives a star by one step bearing the digits of the tens of the dates.
The single figure of the drawing represents an embodiment of the object of the invention given by way of example.
At the center of the mechanism shown is the cannon wheel 1 making two revolutions per day and driving an intermediate wheel 2 with the same number of teeth, which therefore also completes two revolutions per day.
All the teeth 3 of this wheel are cut off, with the exception of one tooth 4, which is therefore longer than the others.
Twice a day this tooth acts on a tooth of a crown 5 having twenty teeth 6 and bearing the digits of the date units, that is to say from zero to nine, all repeated twice in succession, as seen in 7. Thus , any date unit digit, appearing at midnight in the window re presented by frame 8 in phantom lines, will be replaced at noon on the second revolution of wheel 2 by a second identical number, which will not appear until following midnight, to make room for the number which follows it.
A jumper 9, pivoted at 10, fixes the positions of the toothed ring 5.
Inside this crown is a four-pointed star 11, bearing the digits of the tens of dates, or from zero to three. Between the last number nine carried by the crown 5 and the first zero not shown in the drawing due to a partial tearing of the part of the crown bearing the said numbers, there is an additional tooth 12, acting on the star 11 to each of its passages to change the tens number.
A spring 13 serves both to press the jumper 9 against the crown and to immobilize the star between two changes of tens of dates. It is therefore common to these two members and held in place simply by two pins 14 of the jumper, between which it passes.
This mechanism has the advantage of allowing the construction of a very flat caliber with a very large aperture. It is advantageous to add to it a corrective organ acting on the crown of the units, as well as on the star of the tens, to be able to pass from the twenty-eighth, twenty-ninth, thirtieth, respectively the thirty-first day of an end of month on the first day of the following month.
