La montre representde aux fig. 1 ä 9 com- prend une masse rotative de remontage dont la planche est designee par 1. Cette masse porte un arbre 2, dont une embase 2a est chassee dans la planche 1, qui tourne dans deux paliers formes de deux pierres 3 et 4. Ces pierres sont chassees dans un corps de palier 5 en forme de manchon. Ce corps de palier presente une embase 5a sur laquelle est pratiqud un siege tronconique 6 prenant appui sur un siege cor- respondant 7 pratique dans un pont 8 du bäti du mouvement. Un ressort annulaire 9, repre- sent6 en detail dans les fig. 6 et 7, penbtre par- tiellement dans des degagements 10 pratiqu6s dans la face ext6rieure du corps de palier 5. Ce ressort est dispos6 dans une creusure 11 prati- quee dans 1e pont 8 ; il est constitu6 par une laure ondulee de maniere ä agir axialement sur 1e corps de palier et ä maintenir les deux sur- faces coniques 6 et 7 appliqu6es Tune contre Fautre, ce qui assure 1e centrage du corps de palier. En outre, 1'embase 5a presente une sur- face de but6e plane 12, transversale ä Faxe du palier et maintenue appliqu6e contre la surface correspondante 13 du pont B. Le ressort 9 pre- sente des saillies interieures 9a (fig. 7) qui p6 nätrent dans les degagements 10 du corps de palier 5 (fig. 5). Des entr & s 14 sont pratiqu & s dans 1e corps de palier et font communiquer les degagements 10 avec 1'ext6rieur, pour permet- tre la mise en place du ressort 9. Une roue 45 appartenant au train de remontage tourne li- brement sur une goutte 8a du pont 8 et est maintenue en place par 1'embase 5a du corps de palier 5 ; elle est reli & , dune part, au ba- rillet et, d'autre part, ä la masse, ceci, par exemple, par 1'intermediaire d'un levier oscil- lant uruni d'un cliquet engag6 dans l@a denture de la roue et command6 lui-meme par une came montee sur la masse. The watch shown in Figs. 1 to 9 comprises a rotary winding mass whose plate is designated by 1. This mass carries a shaft 2, a base 2a of which is driven into plate 1, which rotates in two bearings in the form of two stones 3 and 4. These stones are driven into a bearing body 5 in the form of a sleeve. This bearing body has a base 5a on which is practiced a tapered seat 6 resting on a corresponding seat 7 practiced in a bridge 8 of the frame of the movement. An annular spring 9, shown in detail in Figs. 6 and 7, partially penbtre in clearances 10 made in the outer face of the bearing body 5. This spring is disposed in a recess 11 made in the bridge 8; it is constituted by a corrugated laurel so as to act axially on the bearing body and to maintain the two conical surfaces 6 and 7 applied one against the other, which ensures the centering of the bearing body. Furthermore, the base 5a has a planar abutment surface 12, transverse to the bearing surface and kept pressed against the corresponding surface 13 of the bridge B. The spring 9 has internal projections 9a (fig. 7) which p6 enter the clearances 10 of the bearing housing 5 (fig. 5). Inputs 14 are made in the bearing body and cause the clearances 10 to communicate with the outside, to allow the positioning of the spring 9. A wheel 45 belonging to the winding train rotates freely on the a drop 8a of the bridge 8 and is held in place by the base 5a of the bearing body 5; it is connected, on the one hand, to the barrel and, on the other hand, to the mass, this, for example, by means of an oscillating lever uruni with a pawl engaged in the toothing of the wheel and itself controlled by a cam mounted on the mass.

La masse est maintenue en place par un verrou 15 presentant une partie coud6e 15a tra- versant un trou 16 de 1'arbre 2 et penetrant entre les deux pierres 3 et 4. Ce verrou 15 est maintenu en place sur la planche 1 de la masse par un rivet 17 dont la tete 17a est logee dans une creusure 18 pratiquee sur la face inferieure de la planche 1. Ce verrou peut coulisser longi- tudinalement de maniere que son extr6mit6 15a puisse etre d6gagee des pierres 3 et 4, ce qui permet 1e & montage de la masse. Il est main- tenu dans sa position de travail, representee dans la fig. 2, par la tete 19a dune cheville 19 logee dans la planche 1, et qui penetre partiel- lement dans un trou 20 pratique dans 1e verrou. The mass is held in place by a lock 15 having a bent part 15a passing through a hole 16 of the shaft 2 and penetrating between the two stones 3 and 4. This lock 15 is held in place on the board 1 of the mass. by a rivet 17, the head 17a of which is housed in a hollow 18 made on the underside of the board 1. This lock can slide longitudinally so that its end 15a can be released from the stones 3 and 4, which allows the & assembly of the mass. It is kept in its working position, represented in fig. 2, through the head 19a of a pin 19 housed in the board 1, and which partially penetrates a convenient hole 20 in the latch.

Lorsque la masse la, situee ä la periph6rie de la planche 1, represent6e dans la fig. 8, subit un choc axial, la planche 1 tend ä se pla- cer obliquement par rapport au plan du mou- vement (fig. 3). Le ressort 9 cäde alors, ce qui permet au corps de palier 5 de se d6placer ; ce ressort rappelle ensuite 1e corps de palier dans sa position normale. When the mass 1a, located at the periphery of the board 1, represented in fig. 8, undergoes an axial shock, the board 1 tends to place itself obliquely with respect to the plane of the movement (fig. 3). The spring 9 then yields, which allows the bearing body 5 to move; this spring then returns the bearing housing to its normal position.

Lorsque la masse subit un choc radial, elle se & place lateralement, comme Findique la fig. 4. Gräce ä Faction des deux RTI ID="0002.0277" WI="12" HE="4" LX="1632" LY="361"> surfaces tron- coniques 6 et 7 Tune sur 1'autre, le deplacement lateral provoque un d6placement axial du corps de palier 5, ä Fencontre de Faction du ressort de rappel 9. When the mass undergoes a radial shock, it moves laterally, as shown in fig. 4. Thanks to the action of the two RTI ID="0002.0277" WI="12" HE="4" LX="1632" LY="361"> truncated surfaces 6 and 7 on each other, the lateral displacement causes an axial displacement of the bearing body 5, against the action of the return spring 9.

Comme an 1e voit dans la fig. 8, la partie la constituant la masse de remontage, et qui a la forme d'un demi-cercle, occupe un espace situ6 entre 1e bäti 20 du mouvement, 1e fond 21 de la boite et la carrure 22. Lorsque cette masse subit un choc, eile vient buter contre 1'un de ces el6ments. Ainsi, dans la fig. 9, la masse est representee lors d'un choc radial ten- dant ä la deplacer vers 1'exterieur : son d6pla- cement est limite par la face interieure 23 de la carrure 22. Lors d'un choc radial dirig6 vers Finterieur, la masse bute contre la face ext6- rieure 24 du bäti 20 du mouvement. En cas de choc axial, la masse bute soit contre la face 25 du bäti 20, soit contre la face 26 du fond 21 (fig. 9). As seen in fig. 8, part la constituting the winding mass, and which has the shape of a semi-circle, occupies a space situated between the first frame 20 of the movement, the first back 21 of the case and the middle part 22. When this mass undergoes a shock, it comes up against one of these elements. Thus, in fig. 9, the mass is shown during a radial impact tending to move it outwards: its movement is limited by the inner face 23 of the middle part 22. During a radial impact directed towards the inside, the mass abuts against the outer face 24 of the frame 20 of the movement. In the event of an axial impact, the mass abuts either against the face 25 of the frame 20, or against the face 26 of the bottom 21 (FIG. 9).

La boite represent6e dans les fig. 8 et 9 est en trois pieces, ä savoir fond 21, carrure 22 et lunette 27 ; en variante, la meine dispo- sition pourrait etre appliquee ä une montre dopt la boite serait en deux pieces (fig. 10), ä savoir un fond 28, une carrure-lunette 29, 1'emboitage du mouvement se faisant au moyen d'un cadre d'encageage 30, ou meine Jans une boite 6tan- che (fig. 11) dans laquelle 1e fond 31 serait viss6 dans la carrure-lunette 32, avec interposi- tion d'un joint d'etancheit6 33, le mouvement 6tant maintenu dans la boite par la pression que 1e fond exerce sur des 61ements 61astiques non repr6sent6s du cadre d'encageage 34. The box represented in figs. 8 and 9 is in three parts, namely back 21, middle 22 and bezel 27; as a variant, the same arrangement could be applied to a watch whose case would be in two parts (fig. 10), namely a back 28, a middle-bezel 29, the casing of the movement being done by means of a casing frame 30, or even a sealed box (fig. 11) in which the back 31 would be screwed into the caseband-bezel 32, with the interposition of a seal 33, the movement being maintained in the box by the pressure that the bottom exerts on the not shown 61elements of the caging frame 34.

Les surfaces tronconiques 6 et 7 assurant le centrage du corps de palier 5 pourraient eire remplac6es par d'autres surfaces ou meine par des aretes. Ainsi, dans la fig. 12, an a repr6- sente schematiquement an detail dune variante dans lequel 1e corps de palier, d6signe par 35, pr6sente une surface tronconique 36 sur la- quelle prend appui 1'arete 37 d'un epaulement du pont 38 du bäti du mouvement. 0n pour- rafft prevoir 1'inverse, c'est-ä-dire la construc- tion dans laquelle ce serait 1e corps de palier qui presenterait une arete en contact avec un siege du pont. La surface du siege pourrait aussi ne pas eire tronconique, mais, par exem- ple, eire form & dune portion de surface sphe- rique, ou de tore. The frustoconical surfaces 6 and 7 ensuring the centering of the bearing body 5 could be replaced by other surfaces or even by edges. Thus, in fig. 12, an a schematically represents in detail a variant in which the first bearing body, denoted by 35, has a frustoconical surface 36 on which bears the edge 37 of a shoulder of the bridge 38 of the frame of the movement. It would be possible to provide the converse, that is to say the construction in which it would be the bearing housing which would present an edge in contact with a seat of the bridge. The surface of the seat could also not be frustoconical, but, for example, be formed from a portion of spherical surface, or from a torus.

Enfin, dans la variante de la fig. 13, 1e verrou 15 de la premiere forme d'execution porte, ä la place du rivet 17, une bride 39 fixee par un rivet 40, s'etendant jusqu'au voi- sinage de la partie p6ripherique 41a de la masse de remontage 41. Cette bride 39 est cou- d6e en 39a, son extremite penetrant sous un rebord annulaire 42a du pont 42 du remon- toir automatique. Une cheville 43 portee par la masse 41a traverse un trou de la partie 39a de la bride 39 et sert au guidage de celle-ci. Lorsque la bride 39 occupe la position repre- sentee dans la fig. 13, correspondant ä la posi- tion du verrou 15 representee dans la fig. 2, l'extremite 39a de la bride 39 vient buter con- tre 1e rebord 42a du pont 42 lors d'un choc axial dirige vers 1e haut, ou contre 1e bäti 44 du mouvement Tors d'un choc axial dirig6 vers 1e bas. La limitation des deplacements axiaux de la masse est ainsi independante de la boite de la montre, ce qui n'etait pas 1e cas dans la forme d'execution de la fig. 9, par exemple. Finally, in the variant of FIG. 13, the lock 15 of the first embodiment carries, in place of the rivet 17, a flange 39 fixed by a rivet 40, extending to the vicinity of the peripheral part 41a of the winding mass 41 This flange 39 is bent at 39a, its end penetrating under an annular flange 42a of the bridge 42 of the automatic winding device. A pin 43 carried by mass 41a passes through a hole in part 39a of flange 39 and serves to guide the latter. When the flange 39 occupies the position shown in FIG. 13, corresponding to the position of lock 15 shown in FIG. 2, end 39a of flange 39 abuts rim 42a of bridge 42 in an upwardly directed axial impact, or against frame 44 in the Tors motion of a downwardly directed axial impact. The limitation of the axial displacements of the mass is thus independent of the case of the watch, which was not the first case in the embodiment of FIG. 9, for example.

Pour degager la masse, lors de son demon- tage, an degage 1'extremit6 15a du verrou, comme c'est 1e cas dans la forme d'execution de la fig. 2, ce qui fait en meme temps coulis- ser 1'extremite 39a de la bride 39 sur la che- ville 43 et degage ainsi cette extremite de 1'epaulement 42a du pont 42. To release the mass, during its dismantling, an releases the extremity 15a of the lock, as is the case in the embodiment of FIG. 2, which at the same time causes the end 39a of the flange 39 to slide over the pin 43 and thus disengages this end of the shoulder 42a from the bridge 42.
