Abstract

610,389. Balances for timepieces. NEWTON, E. P. (Montres Era, Soc. Anon. C. Ruefli-Flury & Cie.). April 3, 1946, No. 10356. [Class 139] A balance wheel for clocks and watches has at least one incision in its rim, a portion of the rim being partially detached therefrom, but connected therewith by a deformable portion whereby said partially detached portion is adapted to be forcibly displaced to regulate the arc of movement of the balance wheel. As shown in Fig. 1, the rim 2 of a balance wheel 1 is provided with two slots 3, 3' shaped as shown to provide lugs 5, 5<1> having neck portions 6, 6' respectively. The lugs 5, 5' may be radially displaced by a pair of pincers to regulate the arc of movement of the balance wheel. In another embodiment, Fig. 3, the balance wheel rim 2 is provided with two (or more) U-shaped slots 7, 7<1> and the arc of movement of the balance is adjusted by radial displacement of the tongues 10, 10'. Specification 605,690 is referred to.
