Abstract
1,163,706. Electric timepieces. CENTRE ELECTRONIQUE HORLOGER S.A. March 1, 1968 [March 31, 1967], No.10041/68. Heading G3T. A mechanical resonator for a timepiece comprises two branches 1, 2 adapted to oscillate in phase opposition, each having at its free end a mass 5, 6 belonging to a transducer maintaining the vibrations of the resonator and each branch having a flexible part 12, 13 to allow displacement of the masses under the influence of gravity in order to reduce the charge in frequency of the resonator due to its change in orientation. The masses oscillate in the direction of the line 11 but are displaced in a direction having a component perpendicular to the line 11 depending on the orientation of the resonator. Members 7, 8 are provided for fine adjustment of the frequency of oscillation of the resonator. In a modification the resonator comprises two parallel straight arms each having at its free end an inwardly facing U-shaped arm positioned at right angles to the straight arms. The flexible part is provided by the curved portion of each U-shaped arm to the free ends of which the masses are secured.
