Description

Raquetterie. Snowshoeing.

Lobjet de la presente invention est une raquetterie qui est caracterisee en ce qu'elle comporte un @coqueret au.quel est fixe 1e dis positif de fixation du spiral. The object of the present invention is a racket which is characterized in that it comprises a @coqueret au.quel is fixed the first positive device for fixing the hairspring.

Cette construction permet de mo,difier, concentriquement ä laxe du balancier, ledit dispositif de fixation du spiral, ce qui, dans bien des cas, specialement dans 1e reglage des montres munies d'un spinal en elinvar associe ä un balancier a,nnulaire mono-me tallique sans vis reglante, fa-cilite con.side rablement les operations. This construction makes it possible to modify, concentrically to the axis of the balance wheel, said device for fixing the hairspring, which, in many cases, especially in the first adjustment of watches provided with a spinal in elinvar associated with a monolithic annular balance wheel. metal without adjusting screw, considerably facilitates operations.

De preference, 1e coqueret precite Sera muni d'un appendice perpendiculaire .au plan general de la raquetterie et auquel 1'extre mite du spiral se fixera par une vis, ceci en remplacement du mode d'attache habituel par goupillage sur un piton. Preferably, the aforementioned first cup will be provided with an appendage perpendicular to the general plane of the racking and to which the end of the hairspring will be fixed by a screw, this replacing the usual mode of attachment by pinning on a piton.

Il est repr6sente au dessin ci-annexe, ä titre d'exemple, dettx formes d'execution ed'une raquetterie selon 1'invention. There is shown in the appended drawing, by way of example, two forms of execution of a racket according to the invention.

La fig. 1 est une vue en plan de 1a Pre miere, tandis que la fig. 2 en est une coupe stlon la ligne II-II de fig. 1; La fig. 3 est une coupe en' plan de la deuxieme forme d'execution, et la fig. 4 est une coupe selon la ligne IV IV de fig. 3. fig. 1 is a plan view of the First, while FIG. 2 is a section along line II-II of FIG. 1; fig. 3 is a plan section of the second embodiment, and FIG. 4 is a section along line IV IV of FIG. 3.

En se referant ä la Premiere forme cl'exe cution, a est 1e coq dune montre ä l'extre mit6 duquel est fixe un coqueret b et ceci ati moyen de trois vis c dont les tiges je traversent Jans des tr.ous en forme d'arcs de cercle concentriques ä laxe d'os.cillation du balancier. Ces vis sont @, 120, les unes des autres, si bien que 1e coqueret peut non seulement etre tourne d'un angle egal ä 1'arc de ces ouvertures, mais peut etre egalement amene dans des positions angulaires distantes de 120 et plus de celle qui est rep,reseutee. Referring to the First Form of Execution, a is the cock of a watch at the end of which is fixed a cover b and this is done by means of three screws c whose rods i pass through holes in the shape of a circular arcs concentric with the axis of oscillation of the balance wheel. These screws are @, 120, from each other, so that the first cup can not only be rotated by an angle equal to the arc of these openings, but can also be brought into angular positions distant from 120 and more than that which is rep, reseute.

Le coqueret possede un appendice d qui s'eleve perpendnculairement au plan general de la raquetterie (fig. 2) et Jans lequel prend une vis e destinee ä appuyer une Plaque f contre 1'appendice d afin de serren sur .ce dernier 1'extr.emite du sp.iral g. The cockerel has an appendage d which rises perpendicularly to the general plane of the rack (fig. 2) and which takes a screw e intended to press a Plate f against the appendage d in order to tighten the end on the latter. .emite of the sp.iral g.

La raquette h est ici formee d'un anneau ouvert dopt les .extremites libres sont recotir bees ä peu pres radialement et portent l'une les chevilles de reglage i et 1'autre une vis micro@metrique 1c qui prend appili sur 1'appen dice du coqueret pour tourner la. raquette de 1'angle desire. The racket h is here formed of an open ring endowed with the free ends being recotir bees approximately radially and carrying one the adjustment pegs i and the other a micrometric screw 1c which takes appili on the appen dice du coqueret to turn the. racket at the desired angle.

Dans certaines pieces, la raquette pourra etre construite comme d'ordinaire c'est-ä-dire posséder une queue 1. telle due montrée en traits et points au dessin. In some parts, the racket may be constructed as usual, that is to say have a tail 1, as shown in lines and dots in the drawing.

Le centrage du coqueret b est assuré par un épaulement dégagé à son intérieur et s'ap- puya.nt sur le sertissage wd du contre-pivot. The centering of the shell b is ensured by a clear shoulder on its inside and rests on the crimping wd of the counter-pivot.

En se référant aux fig. 3 et d, le coqueret b' est fixé à demeure au moyen de trois vis cl sur un pont annulaire a# dont la position angulaire peut être ajustée à volonté après desserrage des vis o. Le coqueret b' est, part les trou; permettant son déplacement relativement au pont qui le porte, construit comme celui qui a été décrit en regard des fig. 1 et ?. Lai raquette h1 est. solidaire d'une couronne partiellement dentée h en prise avec un secteur denté q au moyen du quel on peut déplacer les goupilles i angu- lairement autour de l'axe du balancier. Referring to Figs. 3 and d, the cover b' is fixed permanently by means of three screws cl on an annular bridge a# whose angular position can be adjusted at will after loosening the screws o. The cockerel b' is, apart from the holes; allowing its displacement relative to the bridge which carries it, constructed like that which has been described with regard to FIGS. 1 and ?. Lai racket h1 is. integral with a partially toothed crown h engaged with a toothed sector q by means of which the pins i can be moved angularly around the axis of the balance wheel.
