FIELD: physics; clocks.SUBSTANCE: invention relates to an anchor lever (1) for a clock anchor escapement, comprising at least one fork having arms (3; 4) for interaction with a balance, which are bounded by a recess (2). In said recess (2), the fork comprises at least one said arm (3; 4), having a cut (5; 6) and/or a chamber (30), wherein said cut (5; 6) and/or a chamber (30) are such that the corresponding arm is imparted with flexibility, which enables to cushion the impact during each pulse owing to absorption of part of the impact energy and subsequent return thereof after said impact.EFFECT: providing elasticity of the contact area between the anchor lever and the balance while meeting defined spatial requirements.15 cl, 23 dwg |
