Description

  

  Ressort de barillet.    L'objet de la présente invention est un  ressort de barillet qui offre l'avantage de  fournir une force motrice moins variable, en  fonction du nombre de tours dont il est armé,  que les ressorts de barillet en usage actuelle  ment. Ce ressort est caractérisé en ce que  la section transversale utile de la lame  augmente d'une extrémité à l'autre du ressort,  au moins sur la plus grande partie de la  longueur de ce dernier, l'épaisseur de la lame  étant constante.  



  Le dessin ci-joint montre, à titre d'exem  ples, deux formes d'exécution de ce ressort  de barillet.  



  La     fig.    1 en représente une première  forme d'exécution, le ressort étant montré  développé en élévation;  La     fig.    2 en est une coupe suivant la  ligne     A-B    de la     fig.    1;  La     fig.    3 montre la seconde forme d'exé  cution, qui est représentée de la même ma  nière que celle de la     fig.    1;  La     fig.    4 en est une coupe suivant la  ligne     C-D    de la     fig.    3.  



  Le ressort suivant les     fig.    1 et 2 est  formé par une lame a dont l'épaisseur est    constante d'un bout à l'autre. L'extrémité b  est celle qui s'accroche à     la.    bonde, tandis  que l'extrémité c, formée par une oreille, est  destinée à être figée à la paroi du barillet.  Entre l'oreille c et l'extrémité b, la hauteur  de la lame augmente progressivement, ce qui  correspond à une augmentation progressive  de la section transversale utile de la lame.  



  Les     fig.    3 et 4 montrent un ressort de  barillet formé par une lame a' dont l'épais  seur et la hauteur sont constantes d'un bout  à l'autre. Les extrémités b' et c' correspon  dent respectivement à l'extrémité intérieure  et à l'extrémité extérieure du ressort de ba  rillet. La section transversale utile de la  lame a' varie également d'une extrémité à  l'autre du ressort, par le fait que la lame       présénte    un évidement médian d s'étendant  sur presque toute la longueur du ressort. Cet  évidement prend naissance près de l'extrémité  b' et s'étend progressivement dans le sens de  la hauteur de la lame pour atteindre sa  plus grande largeur prés de l'extrémité c'.

    Comme dans l'exemple donné par les     fig.    1  et 2, la section transversale utile de la lame  est par conséquent plus petite dans la partie      extérieure du ressort. L'évidement d peut  être obtenu, par exemple par fraisage; sa  forme et son étendue peuvent     différer    de  l'exemple représenté.  



  Il en est de même de la forme et des  dimensions du ressort représenté aux     fig.    1  et 2.



  Barrel spring. The object of the present invention is a barrel spring which offers the advantage of providing a driving force which is less variable, as a function of the number of turns with which it is loaded, than the barrel springs in current use. This spring is characterized in that the useful cross section of the leaf increases from one end of the spring to the other, at least over the greater part of the length of the latter, the thickness of the leaf being constant.



  The accompanying drawing shows, by way of example, two embodiments of this barrel spring.



  Fig. 1 represents a first embodiment thereof, the spring being shown developed in elevation; Fig. 2 is a section taken along line A-B of FIG. 1; Fig. 3 shows the second embodiment, which is represented in the same way as that of FIG. 1; Fig. 4 is a section taken along the line C-D of FIG. 3.



  The spring according to fig. 1 and 2 is formed by a blade a whose thickness is constant from one end to the other. The end b is the one that hooks to the. bung, while the end c, formed by an ear, is intended to be fixed to the wall of the barrel. Between the ear c and the end b, the height of the blade gradually increases, which corresponds to a progressive increase in the useful cross section of the blade.



  Figs. 3 and 4 show a barrel spring formed by a blade a 'whose thickness and height are constant from end to end. The ends b 'and c' correspond respectively to the inner end and to the outer end of the bay spring. The useful cross section of the leaf a 'also varies from one end of the spring to the other, in that the leaf has a central recess d extending almost the entire length of the spring. This recess originates near the end b 'and gradually extends in the direction of the height of the blade to reach its greatest width near the end c'.

    As in the example given by FIGS. 1 and 2, the useful cross section of the leaf is therefore smaller in the outer part of the spring. The recess d can be obtained, for example by milling; its shape and extent may differ from the example shown.



  The same applies to the shape and dimensions of the spring shown in FIGS. 1 and 2.
