The escape wheel is geared to the watch's wheel train, which applies torque to it from the mainspring. The rotation of the escape wheel is controlled by the pallets. The escape wheel has specially shaped teeth of either ratchet or club form, which interact with the two jewels called the entrance and exit pallets.
The anchor consists of an escape wheel with pointed, backward slanted teeth, and an "anchor"-shaped piece pivoted above it which rocks from side to side, linked to the pendulum. The anchor has slanted pallets on the arms which alternately catch on the teeth of the escape wheel, receiving impulses.
The pins and part of escape wheel are visible at bottom center. The GIF is slowed down to make the mechanism movement easier to see. A Roskopf , pin-lever , or pin-pallet escapement is an inexpensive, less accurate version of the lever escapement , used in mechanical alarm clocks , kitchen timers , mantel clocks and, until the 1970s, cheap ...
The verge escapement consists of a wheel shaped like a crown, called the escape wheel, with sawtooth-shaped teeth protruding axially toward the front, and with its axis oriented horizontally. [13] [36] In front of it is a vertical rod, the verge, with two metal plates, the pallets, that engage the teeth of the escape wheel at opposite sides ...
Pallet fork with jewel pallets (pink) The pallet fork is above the balance wheel in this watch movement. The pallet fork is a component of the lever escapement of a mechanical watch. [1] The pallet fork and the lever form one component that sits between the escape wheel and the balance wheel. Its purpose is to lock the escape wheel, and release ...
The backward motion of the escape wheel during part of the cycle, called recoil, is one of the disadvantages of the anchor escapement.It results in a temporary reversal of the entire wheel train back to the driving weight with each tick of the clock, causing extra wear in the wheel train, excessive wear to the gear teeth, and inaccuracy.

The fourth wheel also drives the escape wheel of the lever escapement. The escape wheel teeth alternately catch on two fingers called pallets on the arms of the pallet lever, which rocks back and forth. The other end of the lever has a fork which engages with an upright impulse pin on the balance wheel shaft. Each time the balance wheel swings ...
