Abstract

679,416. Clocks and watches. FABRIQUES D'ASSORTIMENTS REUNIES, and TUETEY, P. Aug. 1, 1950 [June 22, 1950], No. 19150/50. Class 139 A lever escapement is characterized in that two stops are provided on the lever horns and are adapted to co-operate with a ring segment integral with the balance staff so as to prevent overbanking of the lever. The ring segment 9, Fig. 2, is integral with or secured to the roller 5 and extends upwardly therefrom to co-operate with the stops 8, Figs. 1 and 2, on the horns 4 of the lever 1. The roller 5 carries the impulse pin 6. In another embodiment, Fig. 4 (not shown), the ring segment extends down from the roller 5.
