We will now proceed to delineate an escape wheel for a detached lever.
The escape wheel, pallet and balance will be found to run quite uniform at from 0.02 mm.
As just stated, the escape wheel is not only dead but actually moving back at the time the release takes place.
This recoil is the slight motion backwards which the escape wheel makes at each tick.
Generally, the part through which the escape wheel gives impulse to the balance or pendulum.
Balance WheelA term often incorrectly applied to the balance itself, but properly it is the escape wheel of the verge escapement.
In a chronometer escapement the second unlocking of the escape wheel from the same cause.
BeatThe strike or blow of the escape wheel upon the pallet or locking device.
For illustration we refer to Fig. 85, where A represents the center of an escape wheel.
Electric ClockA clock in which the pallets moved electrically from a distant mechanism drive the escape wheel and the hands.
