   <Desc/Clms Page number 1> 
    Palier   fixe 'pour pièce d'horlogerie La présente invention se rapporte à un palier fixe pour pièce d'horlogerie. Ce palier est caractérisé par un support de palier dans le fond duquel est chassée une pierre percée, le contre-pivot étant monté dans un chaton engagé lui-même dans un logement du support, logement dont la face interne de la paroi va en s'évasant vers le bas, le pourtour du chaton présentant une portée cylindrique par laquelle ce chaton s'ajuste à tension avec ladite face. 



     Le   dessin ci-annexé représente, à titre d'exemple, une forme d'exécution de l'objet de la présente invention. 



  La    fig.   1 en est une vue en plan et la    fig.   2, une coupe par 11-1l de la    fig.   1. 



  Le palier représenté comprend un support de palier 1 dans le -fond duquel est chassée la pierre percée 2. Au-dessus, ce support présente un logement dont la face interne de la paroi 7 va en s'évasant vers le bas ; dans ce logement est disposée la pierre contre-pivot 5 engagée dans le chaton 4 ; le pourtour de    celui-      ci   présente une portée cylindrique 6 par laquelle ce chaton s'ajuste à tension contre ladite face. 



  Le support de palier présente deux passages 8 diamétralement opposés, plus profonds que l'assise du chaton 4 et par lesquels on peut introduire un outil pour sortir ce chaton de son logement ; au lieu de deux passages, il pourrait, bien entendu, y en avoir un seul ou plusieurs. Ces passages limitent dans la paroi du logement pour le chaton 4 des segments 9 présentant une certaine élasticité qui facilite la mise en place et le maintien du chaton 4.

    Fixed bearing 'for a timepiece The present invention relates to a fixed bearing for a timepiece. This bearing is characterized by a bearing support in the bottom of which is driven a pierced stone, the counter-pivot being mounted in a kitten itself engaged in a housing of the support, housing whose inner face of the wall goes s' flaring downwards, the perimeter of the kitten having a cylindrical scope by which this kitten adjusts to tension with said face.



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



  Fig. 1 is a plan view thereof and FIG. 2, a section through 11-1l of FIG. 1.



  The bearing shown comprises a bearing support 1 in the bottom of which is driven the pierced stone 2. Above, this support has a housing, the inner face of the wall 7 of which widens downwards; in this housing is arranged the counter-pivot stone 5 engaged in the kitten 4; the periphery of the latter has a cylindrical bearing 6 by which this kitten adjusts itself to tension against said face.



  The bearing support has two diametrically opposed passages 8, deeper than the seat of the kitten 4 and through which a tool can be introduced to remove this kitten from its housing; instead of two passages, there could, of course, be one or more. These passages limit in the wall of the housing for the kitten 4 segments 9 having a certain elasticity which facilitates the establishment and maintenance of the kitten 4.
