    Default Deadbeat escapement description (RE: LaBounty)

    THANKS LAB!
    JB, you can readily see the sequence here. Escape wheel is moving CW.
    1. A tooth lands on ENTrance LOCKing face and continues sliding across it.
    This sliding motion and distance is called OVERSWING. During this slide and overswing, wheel freezes - motionless - ergo - deadbeat.
    2. As pendulum returns, tooth meets IMPULSE or LIFT face and there, tooth pushes against face providing impulse to pendulum.
    3. After a brief moment or gap, called, "DROP", a tooth lands on LOCK face of EXIT pallet. Again it glides across the face during overswing. Pendulum returns again and another impulse provided to pendulum as tooth pushes against EXIT impulse (LIFT) face. Drop precedes next entrance lock.
    The terms used in this diagram are the same for a RECOIL escapement altho there are two differences in motion and design.
    1. After lock, pallet pushes wheel and entire train backwards - ergo recoil.
    It is the energy or potential stored in this recoil that provides impulse to the pendulum therefore;
    2. There are no impulse faces on the pallets and the pallet angles will differ from a deadbeat.

    Pretty general in terms. Just a supplement to the thread we already have..
