1980 - Co-Axial concept escapement
Back to Timeline
George Daniels designed Co-Axial to solve the problem of sliding friction when supplying energy to the balance. In Co-Axial escapement sliding friction was almost eliminated and replaced by rolling friction.
The ways of transmitting the drive impulse to the balance in the Swiss and Co-Axial escapement:
Sliding motion, sliding friction: Pushing motion, rolling resistance (below):
