Deadbeat escapement [37] diagram showing escape wheel (a), pallets (b), and pendulum crutch (c) The Graham or deadbeat escapement was an improvement of the anchor escapement first made by Thomas Tompion to a design by Richard Towneley in 1675, [38] [39] [40] although it is often credited to Tompion's successor George Graham who popularized it ...
The deadbeat escapement has two faces to the pallets: a "locking", or "dead", face, with a curved surface concentric with the axis on which the anchor rotates, and a sloping "impulse" face. [8] When an escape wheel tooth is resting against one of the dead faces, its force is directed through the anchor's pivot axis, so it gives no impulse to ...
