Magnetic escapement

Various arrangements have been tried to silence the tick of a clock, but none so successful as the magnetic escapement, in which energy is transferred from the movement to the pendulum by magnetic attraction. In a magnetic escapement invented by C. F. Clifford of Horstmann Clifford Magnetics Ltd, and similar to one marketed a few years ago, the escape wheel has a sine wave shaped rim, which runs between the poles of a magnet mounted in the upper part of the pendulum. The spokes and teeth on the escape wheel allow for the pendulum's free swing, impulse being given to the pendulum by the half-sine wave sections of the escape wheel rim. The escapement has been used in an electrically maintained, transistor-switched, tuning-fork clock to drive the wheelwork from the vibrations of the tuning fork.
