    How do ratchets work?
    On mechanisms that receive their power from a wound spring, such as watches and clocks, ratchets such as that shown at C in the Figure are used. The pawl Q pivots on a fixed axis and rides over the pointed teeth when the spring is being wound but prevents rotation of the wheel in a clockwise direction.
