Description

  

  Mouvement d'horloge     électrique.       Dans les horloges électriques ordinaires,  l'aiguille des secondes     tourne    d'un     mouve,     ment uniforme. Or, pour certaines mesures et  pour     pouvoir        mieux    chronométrer une durée  quelconque, il y aurait avantage à avoir une  aiguille des secondes qui saute à chaque se  conde.     L'oeil    est habitué à l'aiguille des  secondes sautante des horloges non électriques  et préfère ce système.  



  L'invention a pour but d'obtenir que l'ai  guille des secondes avance     brusquement    à cha  que seconde, et reste immobile entre temps.  



  Le mouvement d'horloge électrique selon  la présente invention est caractérisé en ce  qu'il comporte un rotor, porteur d'un pignon  engrenant avec     une    roue qui tourne à
EMI0001.0009  
       toKir     par seconde et qui porte n chevilles réguliè  rement réparties sur une circonférence con  centrique, lesquelles viennent, à chaque se  conde, faire tourner d'une dent la roue des       secondes.     



  Le     dessin    annexé représente, à titre  d'exemple,     ,une    forme d'exécution d'un mou  vement     d'horloge    selon l'invention. Il n'est  montré de ce mouvement que ce que la com  préhension de l'invention exige.  



  La     fig.    1 est une vue en plan,  la     fig.    2 une coupe suivant la ligne     II-II     de la     fig.1.     



  Le mouvement représenté comporte un  stator 1, un rotor 2, porteur d'un pignon 3.  Ce dernier engrène avec une roue 4 sur la.    quelle sont fixés deux chevilles 5 diamétrale  ment opposées. Chacune de ces chevilles en  grène avec une roue 6, munie de soixante  dents et dont l'axe porte l'aiguille des se  condes.  



  -Un ressort sautoir 7 vient s'appuyer sur  la roue 6.  



  Le rotor et son pignon sont pivotés dans  les platines 8 et 9. Il en est de même de la  roue 4 et de la roue des secondes 6. Les  organes de la     minuterie    10 sont ceux d'une  horloge ordinaire.  



  La vitesse de rotation du rotor et le nom  bre de dents respectif du pignon 3 et de la  roue 4 sont déterminés de faon que la roue  4. fasse exactement     un    demi-tour par seconde.  



  A cause de la vitesse imprimée à la roue 4,  une cheville se présente à chaque     seconde    de  vant une dent de la     route    des secondes 6 et la  fait     tourner    d'un cran.  



  Afin d'immobiliser la roue des secondes  entre deux passages de chevilles, le ressort  sautoir 7 la bloque aussitôt que la cheville l'a  fait tourner d'une dent.  



  Le but de l'invention est ainsi atteint.



  Electric clock movement. In ordinary electric clocks, the seconds hand rotates in a uniform motion. However, for certain measures and in order to be able to better time any duration, it would be advantageous to have a seconds hand which jumps at each second. The eye is used to the jumping seconds hand of non-electric clocks and prefers this system.



  The object of the invention is to obtain that the hand of the seconds advances suddenly to each second, and remains motionless in the meantime.



  The electric clock movement according to the present invention is characterized in that it comprises a rotor, carrying a pinion meshing with a wheel which turns at
EMI0001.0009
       toKir per second and which has n pegs regularly distributed over a con centric circumference, which, at each second, turn the seconds wheel by one tooth.



  The appended drawing represents, by way of example, an embodiment of a clock movement according to the invention. It is shown of this movement only what the understanding of the invention requires.



  Fig. 1 is a plan view, FIG. 2 a section on line II-II of fig.1.



  The movement shown comprises a stator 1, a rotor 2, carrying a pinion 3. The latter meshes with a wheel 4 on the. which are fixed two dowels 5 diametrically opposed ment. Each of these pegs in grene with a wheel 6, provided with sixty teeth and the axis of which carries the second hand.



  -A jumper spring 7 comes to rest on the wheel 6.



  The rotor and its pinion are pivoted in the plates 8 and 9. The same applies to the wheel 4 and the seconds wheel 6. The components of the timer 10 are those of an ordinary clock.



  The rotational speed of the rotor and the respective number of teeth of the pinion 3 and of the wheel 4 are determined so that the wheel 4 makes exactly half a turn per second.



  Because of the speed imprinted on the wheel 4, a pin comes up every second ahead of a tooth of the 6 seconds road and turns it up a notch.



  In order to immobilize the seconds wheel between two pin passages, the jumper spring 7 blocks it as soon as the pin has turned it by one tooth.



  The aim of the invention is thus achieved.
