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 ...
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 ...

[2] The escapement mechanism, which changes the rotational motion of the clock's gears to pulses to drive the torsion pendulum, works rather like an anchor escapement. A crutch device at the top of the torsion spring engages a lever with two anchor-shaped arms; the two arms alternately engage the teeth of the escape wheel.
The Riefler escapement is a mechanical escapement for precision pendulum clocks invented and patented [1] by German instrument maker Sigmund Riefler in 1889. [2] It was used in the astronomical regulator clocks made by his German firm Clemens Riefler from 1890 to 1965, [ 3 ] which were perhaps the most accurate all-mechanical pendulum clocks made.
