Balance Spring Attachment via Rotating Frame for Timepiece

The patent introduces an intermediary mechanism (the stud moving along the circular path) that transfers energy to the balance spring without direct mechanical coupling between the escapement and the balance. This intermediary action maintains oscillation amplitude while minimizing frequency disturbance, as the energy transfer occurs through positional displacement rather than direct force application.

The escapement mechanism performs preliminary action by moving the stud along a circular path in advance, storing potential energy in the balance spring before the balance passes the impulse point. This preliminary energy storage and gradual release reduces sudden shocks to the oscillation system, thereby maintaining amplitude while preserving frequency stability.

The stud moves periodically along a circular path with a period that is a sub-multiple of the balance oscillation period. This periodic motion synchronizes with the oscillation cycles, providing regular energy input that maintains amplitude while the synchronized timing prevents chaotic interactions that could cause galloping.

The patent changes the parameter of the attachment point position dynamically by moving the stud along a circular path rather than keeping it fixed. This parameter change allows continuous adjustment of the energy transfer timing and magnitude, optimizing amplitude maintenance while avoiding positions that would induce galloping or excessive mechanical disturbances.
