Ratchet (device) - Wikipedia
A ratchet (occasionally spelled rachet) is a mechanical device that allows continuous linear or rotary motion in only one direction while preventing motion in the opposite direction. Ratchets are widely used in machinery and tools.
Ratchet Gears & Pawls - Grainger Industrial Supply
Ratchet gears and pawls allow gear systems to rotate in one direction but prevent them from moving backward. Typical uses include intermittent motion applications, such as stamping dies, lifting equipment, turnstiles, and hand tools.
Ratchets and Pawls Information - GlobalSpec
Ratchets are sometimes called ratchet wheels because they consist of a rotating gear or rack with angled teeth. Pawls, which are sometimes misidentified as ratchets, are thin protrusions that rest against a ratchet to restrict its motion.

Ratcheting to the Rescue: Understanding Different Ratchet …
To understand how ratchet mechanisms work, let's take a closer look at the classic pawl-and-ratchet design. When you apply force in one direction, the pawl engages with the teeth on the ratchet, allowing the ratchet to rotate freely.
