Abstract

Piton de fixation de l'extrémité extérieure d'un ressort-spiral de pièce d'horlogerie. Ce piton est constitué par une pièce tubulaire 3, fendue longitudinalement, engagée par une de ses extrémités dans le trou 5 du porte-piton 2a dans lequel elle se maintient par sa propre élasticité. L'extrémité opposée de ladite pièce tubulaire 3 présente une languette 3a découpée, rabattue vers l'intérieur, diamétralement opposée à la fente longitudinale 4. Cette languette sert à retenir la colle 7 maintenant le spiral 1 assemblé au piton.Fixing eyelet for the outer end of a timepiece hairspring. This eyebolt consists of a tubular part 3, slit longitudinally, engaged by one of its ends in the hole 5 of the eyebolt holder 2a in which it is maintained by its own elasticity. The opposite end of said tubular part 3 has a cutout tongue 3a, folded inwards, diametrically opposite the longitudinal slot 4. This tongue serves to retain the glue 7 holding the hairspring 1 assembled to the eyebolt.
