Anchor escapement is, an increase in amplitude of swing causes a slight increase in period of a pendulum due to circular error, and that this can compensate for the decreased period due to isochronism. Due to this effect a carefully adjusted anchor escapement with polished pallets might be more accurate than a deadbeat. This has been confirmed by at least one modern experiment. Anchor escapement In horology, the anchor escapement is a type of escapement used in pendulum clocks. The escapement is a mechanism in a mechanical clock that maintains the swing of the pendulum by giving it a small push each
Escapement main advantage of the deadbeat is that it eliminated recoil. In the deadbeat, the pallets have a second curved "locking" face on them, concentric about the pivot on which the anchor turns. During the extremities of the pendulum's swing, the escape wheel tooth rests against this locking face, providing no impulse to the pendulum, which prevents recoil. Near the bottom of the pendulum's swing the tooth slides off the locking face onto the angled "impulse" face, giving the pendulum a push, before the pallet releases the tooth. This was the first escapement to separate the locking and impulse actions of
