Pawl (king)
A pawl is a movable lever that engages a fixed component to either prevent movement in one direction or restrain it altogether. As such, it is a type of latch and can also be considered a type of Dog (engineering), dog. It typically consists of a spring-loaded lever that engages a mating component at a steep enough angle to restrain it. Pawls are often tapered, being widened at their pivot for anchoring and narrow at their tip. Applications ;Anchor windlass: A pawl is used in an anchor windlass to prevent a free-spooling chain by grabbing and snubbing an individual link. Similar mechanisms include a Anchor_windlass#Devil's_claw, Devil's claw, or a claw and dog. ;Ratchet: A pawl is used in combination with a ratchet (device), ratchet gear in socket wrenches, bicycle freehubs, winches, and many other applications. ;Ladder: Dog (engineering), Dogs (in the form of pawls) are used on extension ladders to temporarily anchor their sections to one-another. ;Table saw: Pawls are used ...

Winch
A winch is a mechanical device that is used to pull in (wind up) or let out (wind out) or otherwise adjust the tension of a rope or wire rope (also called "cable" or "wire cable"). In its simplest form, it consists of a spool (or drum) attached to a hand crank. Traditionally, winches on ships accumulated wire or rope on the drum; those that do not accumulate, and instead pass on the wire/rope (see yacht photo above), are called capstans. Despite this, sailboat capstans are most often referred to as winches. Winches are the basis of such machines as tow trucks, steam shovels and elevators. More complex designs have gear assemblies and can be powered by electric, hydraulic, pneumatic or internal combustion drives. It might include a solenoid brake and/or a Mechanical brake stretch wrapper, mechanical brake or ratchet (device), ratchet and pawl which prevents it unwinding unless the pawl is retracted. The rope may be stored on the winch. When trimming a line on a sailboat, the ...

Cylinder (firearms)
In firearms, the cylinder is the cylindrical, rotating part of a revolver containing multiple chamber (firearms), chambers, each of which is capable of holding a single cartridge (firearms), cartridge. The cylinder rotates (revolves) around a central axis in the revolver's action (firearms), action to sequentially align each individual chamber with the gun barrel#Bore, barrel bore for repeated firing. Each time the gun is cocked, the cylinder indexing (motion), indexes by one chamber (for five-shooters, by 72Degree (angle), °, for six-shooters, by 60Degree (angle), °, for seven-shooters, by 51.43Degree (angle), °, for eight-shooters, by 45Degree (angle), °, for nine-shooters, by 40Degree (angle), °, and for ten-shooters, by 36Degree (angle), °). Serving the same function as a rotary magazine, the cylinder stores ammunitions within the revolver and allows it to repeating firearm, fire multiple times before needing to reload. Typically revolver cylinders are designed to gene ...

Revolver
A revolver (also called a wheel gun) is a repeating handgun that has at least one barrel and uses a revolving cylinder containing multiple chambers (each holding a single cartridge) for firing. Because most revolver models hold up to six rounds of cartridge before needing to reload, revolvers are also commonly called six shooters. Before firing, cocking the revolver's hammer partially rotates the cylinder, indexing one of the cylinder chambers into alignment with the barrel, allowing the bullet to be fired through the bore. The hammer cocking in nearly all revolvers are manually driven, and can be achieved either by the user using the thumb to directly pull back the hammer (as in single-action), via internal linkage relaying the force of the trigger-pull (as in double-action), or both (as in double/single-action). By sequentially rotating through each chamber, the revolver allows the user to fire multiple times until having to reload the gun, unlike older single-shot fir ...

Automatic Transmission
An automatic transmission (sometimes abbreviated to auto or AT) is a multi-speed transmission used in internal combustion engine-based motor vehicles that does not require any input from the driver to change forward gears under normal driving conditions. It typically includes a transmission, axle, and differential in one integrated assembly, thus technically becoming a transaxle. The most common type of automatic transmission is the hydraulic automatic, which uses a planetary gearset, hydraulic controls, and a torque converter. Other types of automatic transmissions include continuously variable transmissions (CVT), automated manual transmissions (AMT), and dual-clutch transmissions (DCT). An electronic automatic transmission (EAT) may also be called an electronically controlled transmission (ECT), or electronic automatic transaxle (EATX). A hydraulic automatic transmission may also colloquially called a " slushbox" or simply a "torque converter", although the latter term c ...
