A pawl, click, or detent, for holding or propelling a ratchet wheel, or ratch, etc.
A mechanism composed of a ratchet wheel, or ratch, and pawl. See Ratchet wheel, below, and 2d Ratch.
A notched wheel on the rear of a revolver cylinder which causes the cylinder to rotate when so urged by a lever called a Hand or Pawl.
a device that allows movement in one direction but not the other. It has a toothed shaft or wheel on which a pawl rests. The pawl is pivoted so that it can move over the teeth of the ratchet in one direction. If the pawl or ratchet moves in the reverse direction, the pawl engages the teeth of the ratchet to prevent movement. A pawl may also move to and fro to turn a ratchet wheel in one direction.
A device that permits movement in one direction only.
wheel, usually toothed, operating with a catch of a pawl so as to rotate in one direction only
mechanical device consisting of a toothed wheel or rack engaged with a pawl that permits it to move in only one direction
a device that allows a wheel to turn periodic table of the
a device where a rotation is transfered if it is turning in a certain direction and not otherwise
a mechanism for locking in progress
A mechanism that operates on the principle of the lever to increase hand power. It only makes you feel like you've got super powers.
A toothed wheel or bar that catches and holds a pawl, which thus prevents backward movement.
A serrated edge like that of a saw, sometimes straight and sometimes on a wheel, into which a pawl engages, for producing or (more commonly) restraining motion. See brake ratchet, and pawl.
A mechanism whereby management's equity stake may be increased (or decreased) on the occurrence of various future events, typically when the institutional investor's returns exceed a particular target rate.
A circular-shaped mechanism with uniform ridges. The ratchet allows for line retrieval of intake.
A toothed member for engagement with the pawl. Ratche t binder A toothed member for engagement with the pawl.
A one-way locking mechanism used to hold a load while it is repositioned
A claw tooth bar located on the track (most often on the lift hill) into which the anti-rollback device, or ratchet dog engages that will prevent the train from rolling backwards.
A mechanism by which the successful performance of management reflected in growth in the value of a company is rewarded by progressively increasing their share of the equity.
A mechanical device, consisting of a toothed bar and pawl, that allows motion in one direction only.
A mechanism that allows movement in one direction, but not another, as in a socket wrench.
In mechanical engineering a ratchet is a device used to restrict motion in one direction. This sort of behaviour is useful in many areas, such as in turnstile, spanners (where rotation in confined surfaces can be achieved easily), winders, jacks, hoists and others.
A ratchet, also called a noisemaker (or, when used in Judaism, a gragger or ra'ashan), is an orchestral musical instrument played by percussionists. Operating on the principle of the ratchet device, a gearwheel and a stiff board is mounted on a handle, which can be freely rotated. The handle is held and the whole mechanism is swung around, the momentum making the board click against the gearwheel, making a clicking and rattling noise.
Ratchet is one of the main characters in the Ratchet & Clank series. He is a Lombax, an alien species that resembles a bobcat. At the start of the series, he is a mechanic bored with life and longing for adventure, but in later games is reknowned as a pan-galactic hero.
