Description

  

      Mécanisme    pour faire apparaître alternativement dans des guichets d'un cadran, l'une  et l'autre des deux séries de     chiffres    horaires.    IL existe déjà des mécanismes pour faire  apparaître alternativement, dans les guichets  d'un cadrai, l'une et l'autre des deux séries  de chiffres horaires, c'est-à-dire entre minuit  et midi les     chiffres    de 1 à 12 et entre midi  et minuit les     chiffres    13 à 24.  



       Pour    obtenir ce résultat; l'objet de la pré  sente invention possède deux roues tournant  en sens inverse, lesquelles, par le moyen  d'une came et d'une bascule, font sauter  instantanément en avant     resp.    en arrière un  disque coaxial au cadran et portant les chif  fres, la position de ces derniers étant assurée  par un sautoir agissant alternativement sur  deux coches prévues à la circonférence du  disque.  



  Le dessin ci-joint montre, à titre d'exem  ple,     crie    forme d'exécution de l'objet de l'in  vention.  



  Les     fig.    1 et 2 montrent le mécanisme  dans deux positions différentes et la     fig.    3  représente     une    partie du cadran de ladite  forme d'exécution.  



  Le mécanisme représenté comporte les  deux roues a et a' faisant chacune un tour    en 24 heures en sens inverse, la roue a en  grenant avec le pignon de minuterie et la  roue a' engrenant avec la roue d'heures.  



  Chacune de ces roues porte une came     L          resp.    b', ajustée librement sur son axe et dont  le jeu est assuré par une goupille c fixée dans  la roue.  



  Les cames portent une goupille et un in  dex<I>d</I>     resp.   <I>d'.</I>  



  Sur un pont e,     recouvrant    la roue d'heu  res, est ajusté librement le disque     l    qui est  coaxial au cadran et qui porte les chiffres.  Ce disque est placé immédiatement sous le  cadran.  



  Chacune des positions du disque l est as  surée par l'une des deux coches<I>f</I> et     g    pré  vues à la circonférence du     disque.        Z    et dans  lesquelles pénètre, alternativement, la dent  d'un sautoir h., fixé à la boîte du mécanisme.  



  Le disque     l    a deux dégagements, com  portant chacun une coche<I>i</I> et     i'    disposées  en regard des cames.  



  Chacune des deux roues a et a', en tour  nant,     entraîne    la came qu'elle porte et celle-      ci fait lever une bascule j     resp.    j', comman  dée par     titi    ressort Ii.  



  Quand la pointe de la came     b,    tournant  à droite, arrive en regard de la pointe de la  bascule j, celle-ci déclenche et     pousse    la  came en avant.  



  La goupille de la came pénètre alors dans  la coche<I>i</I> du disque<I>l</I> et l'entraîne assez  loin pour que la dent du sautoir la entre dans  la coche     g.     



  Le disque     porte-chiffres    se trouve alors  dans la position voulue pour que, 12 heures  plus tard, l'index d' puisse pénétrer dans la       coolie    i' et entraîner le disque     l    eu     arrière,     lorsque la bascule j' déclenchera.  



  A 1 heure et à 13 heures, le disque 1 fait  donc     titi    saut instantané.  



  La     fig.    1 représente le mécanisme avec  le disque     porte-chiffres    en place et au moment  où la bascule j va déclencher. Les organes  cachés par le disque sont tracés en pointillé.  



  La     fig.    2 représente la position du     inéca-          nisme    lorsque la bascule j est tombée, le  disque     porte-chiffres    et ses dégagements étant  tracés en pointillé.  



  La     fig.    3 représente une partie du cadran  avec les guichets dans lesquels paraissent,         alternativement,    les heures de 1 à 12 et celles  de 13 à 24.  



  Suivant le genre de mouvements auxquels  ils sont adaptés (simples ou compliqués) les  organes de ce mécanisme peuvent     changer     de place et de forme tout en maintenant les  mêmes rapports entre eux.  



  Cependant l'une des deux roues a et a',  tournant en sens inverse, pourrait être mue  par l'autre.  



  Ledit mécanisme permet d'actionner la  mise à l'heure en avant et en arrière sans  inconvénient.



      Mechanism for showing alternately in apertures of a dial, one and the other of the two series of hour figures. There are already mechanisms for showing alternately, in the counters of a cadrai, one and the other of the two series of hourly digits, that is to say between midnight and noon the digits 1 to 12 and between noon and midnight the numbers 13 to 24.



       To achieve this result; the object of the present invention has two wheels rotating in the opposite direction, which, by means of a cam and a rocker, instantly jump forward resp. behind a disc coaxial with the dial and carrying the figures, the position of the latter being ensured by a jumper acting alternately on two notches provided on the circumference of the disc.



  The accompanying drawing shows, by way of example, an embodiment of the object of the invention.



  Figs. 1 and 2 show the mechanism in two different positions and fig. 3 shows part of the dial of said embodiment.



  The mechanism shown comprises the two wheels a and a 'each making one revolution in 24 hours in the opposite direction, the wheel a meshing with the timer pinion and the wheel a' meshing with the hour wheel.



  Each of these wheels carries a cam L resp. b ', freely adjusted on its axis and the play of which is ensured by a pin c fixed in the wheel.



  The cams have a pin and an in dex <I> d </I> resp. <I> d '. </I>



  On a bridge e, covering the hour wheel, is freely adjusted the disc l which is coaxial with the dial and which bears the numbers. This disc is placed immediately below the dial.



  Each of the positions of the disc l is secured by one of the two checkmarks <I> f </I> and g provided for the circumference of the disc. Z and in which penetrates, alternately, the tooth of a jumper h., Fixed to the case of the mechanism.



  Disk 1 has two undercuts, each with a check mark <I> i </I> and i 'located opposite the cams.



  Each of the two wheels a and a ', by turning, drives the cam which it carries and the latter causes a rocker j resp. j ', commanded by titi spring Ii.



  When the tip of the cam b, turning to the right, comes opposite the tip of the rocker j, the latter releases and pushes the cam forward.



  The cam pin then enters the checkmark <I> i </I> of the disc <I> l </I> and drives it far enough for the jumper tooth to enter it into the notch g.



  The number-bearing disc is then in the desired position so that, 12 hours later, the index d 'can enter the coolie i' and drive the disc l backwards, when the rocker j 'triggers.



  At 1 o'clock and at 1 o'clock, disc 1 therefore makes a titi instant jump.



  Fig. 1 shows the mechanism with the number-holder disc in place and at the moment when the rocker j will trigger. The organs hidden by the disc are drawn in dotted lines.



  Fig. 2 represents the position of the inecanism when the lever j has fallen, the number-holder disc and its clearances being drawn in dotted lines.



  Fig. 3 shows part of the dial with the apertures in which appear, alternately, the hours from 1 to 12 and those from 13 to 24.



  Depending on the kind of movements to which they are adapted (simple or complicated), the organs of this mechanism can change place and shape while maintaining the same relationships between them.



  However, one of the two wheels a and a ', turning in the opposite direction, could be moved by the other.



  Said mechanism makes it possible to activate the time setting forward and backward without inconvenience.
