    Hi all, a silly question, what is the difference and how they work. I am getting confused with recoil and dead beat escapemet, more I look at the diagrams more confusing it gets... I have recently purchased a French marble mantle clock and getting confused what the moment it is as I am missing few parts and I want to salvage any spare parts from few clockers !!, see attached photos..:cyclops: look at the second picture and what I need photo as I have the two spare sides to the pendulum housing !, what kind of movement is it :???:puzzled..is it...thanks in advance...igabrie

    I don't think it is important right now which type it is.
    From the pictures, it seems that you have the anchor that would
    have the pallets. You just need the bushing end and pendulum
    cock.
    You might look through pictures on the message board here and
    see if you can see another that is closer to yours.

    Back to dead beat and recoil.
    A recoil has only one pallet surface on each side that the
    escapement tooth lands on ( it may be curved slightly but is
    often flat ).
    The pallet for a dead beat has two surfaces on each pallet
    that contacts the escapement wheel.
    One surface is curved along the diameter of the pallet relative to
    the anchors arbor. It is called the locking surface. It imparts no
    force to the pendulum and holds the escapement from moving.
    The other surface is the impulse. It is the part that pushes the
    pendulum. It is the angled surface at the end of the pallet.
    When set right, after driving with the impulse face, the drop
    of the escapement teeth to the opposite pallet is onto the
    locking surface ( this is the dead part of the escapement ).
    This allows the pendulum to swing, with only a small amount
    of friction, and the escapement tooth and wheel doesn't move.
    As the pendulum crosses the center of the swing, the escapement
    tooth goes onto the impulse face. This allows the push to the pendulum
    to happen at the center of the swing that is optimal for
    accurate time keeping.
    I hope that helps some.

    A quick "Google Search" yielded the following site

    http://www.angelfire.com/ut/horology/bbigrhm.html

    It is an animation of a Graham Deadbeat Escapement. The following animation (link at the bottom of the page) is of a Recoil Escapement.

    If you want to get really confused (or really knowledgeable, the site has animations for about 8 different types of Clock Escapements and about 6 different watch escapements

    I hope this compliments the information that Tinker has provided.

    cheers
