Anchor escapement made today use it. Tower clocks are one of the few types of pendulum clock which the anchor escapement did not dominate. The varying force applied to the wheel train by the large exterior hands, exposed to wind, snow, and ice loads, was better handled by gravity escapements. 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. When an escape wheel tooth is resting against one of the dead faces, its force is directed through the anchor's
Coaxial escapement Coaxial escapement The coaxial escapement is a type of modern watch escapement mechanism invented by English watchmaker George Daniels. Invented around 1974 and patented in 1980 by English watchmaker George Daniels, the coaxial escapement is a modification of the lever escapement with some features of the detent escapement. Considered by some to be one of the most significant horological advancements since the invention of the lever escapement, the coaxial escapement functions with a system of three pallets that separate the locking function from the impulse, avoiding the sliding friction of the lever escapement. This makes lubrication of the pallets theoretically
