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 ...
Drawing of a Graham, or deadbeat, clock escapement. Alterations: Removed captions and labels, replaced labels in color, added dotted lines, moved arrow from top of wheel to side, drew in pendulum crutch. Labeled parts: (a) escape wheel (b) pallets, showing concentric locking faces (c) pendulum crutch: Date: 8 January 2010, 22:49 (UTC) Source
Animation of an anchor escapement, one of the most common escapements used in pendulum clocks . The escapement is a mechanical linkage that converts the force from the clock's wheel train into impulses that keep the pendulum swinging back and forth. It is the part that makes the "ticking" sound in a working pendulum clock.
The deadbeat escapement invented in 1675 by Richard Towneley and popularised by George Graham around 1715 in his precision "regulator" clocks gradually replaced the anchor escapement [7]: 181, 441 and is now used in most modern pendulum clocks.
Deadbeat, deadbeats or dead-beat may refer to: Deadbeat escapement , a type of escapement used in pendulum clocks Dead-beat control , a problem in discrete control theory of finding an optimal input sequence that will bring the system output to a given setpoint in a finite number of time steps

The anchor escapement originated with Hooke, although it has been argued that it was invented by Clement, [133] or the English clockmaker Joseph Knibb. [ 132 ] The Jesuits made major contributions to the development of pendulum clocks in the 17th and 18th centuries, having had an "unusually keen appreciation of the importance of precision". [ 134 ]
