Abstract
The regulating device, represented by its escapement wheel (5), is kept horizontal by being supported by a platform (3) secured to a counterweight (9) rotatably mounted about an arbour A1, pivoting in a carriage (10) rotatably mounted about an arbour A2 perpendicular to the arbour A1. Escapement wheel 15 meshes with a driving wheel (6) secured to arbour A1 and forming the output of a first differential (11) having at its inputs a kinematic corrective chain (8, 12, 14, 16, 18) and a kinematic drive chain, itself connected to the output of a second differential (21) having at its inputs the barrel wheel (7) and another kinematic corrective chain (22, 24, 26, 28) meshing with a wheel (20) secured to the carriage (10). The device can also act on an automatic winding block (40).
