Abstract
A clockwork movement hammer (1) is used for interacting with heart-shaped cams (20, 21) provided with corresponding axes of rotation (29, 30) which are positioned remotely to each other. More precisely, the hearts (20, 21) are connected to a chronograph timer, whereas the hammer belongs to the resetting mechanism of the chronograph timers. The inventive hammer (1) includes at least one first part (5) movably mounted on the clockwork bottom plate (2) and one second part (17) bearing supporting surfaces (13, 19) which can be bring into contact with the hearts (20, 21) . The two parts (5, 17) of the hammer (1) are connected to each other by at least one swivel-type connection (14, 24) for making it possible to adjust the corresponding positions of the supporting surfaces (18, 19) while a resetting process. Due to particular characteristics thereof, the structural design of the hammer (1) is simple and small-sized.
