Abstract

BALANCIER POUR INSTRUMENTS CHRONOMETRIQUES. LE BALANCIER SELON L'INVENTION COMPORTE DEUX RESSORTS SPIRAUX 1 ET 2 IDENTIQUES AYANT CHACUN LA FORME D'UNE SPIRALE PLATE, CES DEUX RESSORTS ETANT DISPOSES DANS DEUX PLANS PARALLELES NORMAUX A L'AXE 5 DU BALANCIER ET FIXES EN DEUX POINTS DIAMETRALEMENT OPPOSES, PAR UNE EXTREMITE A L'AXE 5 ET PAR L'AUTRE, AU PONT DU BALANCIER; LES DEUX RESSORTS SPIRAUX 1 ET 2 SONT ORIENTES DANS LE MEME SENS MAIS SONT DECALES DE 180 AUTOUR DE L'AXE 5 DU BALANCIER.BALANCER FOR CHRONOMETRIC INSTRUMENTS. THE BALANCER ACCORDING TO THE INVENTION INCLUDES TWO IDENTICAL SPIRAL SPRINGS 1 AND 2 EACH HAVING THE SHAPE OF A FLAT SPIRAL, THESE TWO SPRINGS BEING ARRANGED IN TWO NORMAL PARALLEL PLANS AT AXIS 5 OF THE BALANCER AND FIXED AT TWO PARALLY OPPOSED DIAMETRALLY POINTS, ONE END AT AXIS 5 AND THE OTHER AT THE PONT DU BALANCIER; THE TWO SPIRAL SPRINGS 1 AND 2 ARE ORIENTED IN THE SAME DIRECTION BUT ARE OFFSET OF 180 AROUND AXIS 5 OF THE BALANCER.
