⭐ Core Definition: Shackle

A shackle (or shacklebolt), also known as a gyve, is a U-shaped piece of metal secured with a clevis pin or bolt across the opening, or a hinged metal loop secured with a quick-release locking pin mechanism. The term also applies to handcuffs and other similarly conceived restraint devices that function in a similar manner. Shackles are the primary connecting link in all manner of rigging systems, from boats and ships to industrial crane rigging, as they allow different rigging subsets to be connected or disconnected quickly.

A shackle is also the similarly shaped piece of metal used with a locking mechanism in padlocks. A carabiner is a type of shackle used in mountaineering.

👉 Shackle in the context of Carabiner

A carabiner or karabiner (/ˌkærəˈbnər/), often shortened to biner or to crab, colloquially known as a (climbing) clip, is a specialized type of shackle, a metal loop with a spring-loaded gate used to quickly and reversibly connect components, most notably in safety-critical systems. The word comes from the German Karabiner, short for Karabinerhaken, meaning "carbine hook," as the device was used by carabiniers to attach their carbines to their belts.

Shackle in the context of Statue of Liberty

The Statue of Liberty (Liberty Enlightening the World; French: La Liberté éclairant le monde) is a colossal neoclassical sculpture of a robed and crowned female on Liberty Island in New York Harbor, within New York City. The copper-clad statue, a gift to the United States from the people of France, was designed by French sculptor Frédéric Auguste Bartholdi, and its metal framework built by Gustave Eiffel. The statue was dedicated on October 28, 1886.

The statue is a figure of a classically draped woman, likely inspired by the Roman goddess of liberty, Libertas. In a contrapposto pose, she holds a torch above her head with her right hand, and in her left hand carries a tabula ansata inscribed JULY IV MDCCLXXVI (July 4, 1776, in Roman numerals), the date of the U.S. Declaration of Independence. With her left foot she steps on a broken chain and shackle, commemorating the national abolition of slavery following the American Civil War. After its dedication, the statue became an icon of freedom and of the United States, seen as a symbol of welcome to immigrants arriving by sea.

Shackle in the context of Fishing tackle

Fishing tackle is the equipment used by anglers when fishing. Almost any equipment or gear used in fishing can be called fishing tackle, examples being hooks, lines, baits/lures, rods, reels, floats, sinkers/feeders, nets, spears, gaffs and traps, as well as wires, snaps, beads, spoons, blades, spinners, clevises and tools that make it easy to tie knots.

Tackle attached to the end of a fishing line that gets cast out along with the bait are referred to as terminal tackle. Terminal tackle can include hooks, leaders, floats, sinkers/feeders, swivels and attached snaps and/or split rings. Sometimes the term "rig" is used for a specific assemblage of terminal tackle.

Shackle in the context of Chain

A chain is a serial assembly of connected links typically made of metal, with an overall character similar to that of a rope in that it is flexible and curved in compression, but linear, rigid, and load-bearing in tension. A chain may consist of two or more links. Chains can be classified by their design, which can be dictated by their use:

  • Those designed for lifting, such as when used with a hoist; for pulling; or for securing, such as with a bicycle lock, have links that are torus-shaped, which make the chain flexible in two dimensions (the fixed third dimension being a chain's length). Small chains serving as jewellery are a mostly decorative analogue of such types.
  • Those designed for transferring power in machines have links designed to mesh with the teeth of the sprockets of the machine, and are flexible in only one dimension. They are known as roller chains, though there are also non-roller chains such as block chains.

Two distinct chains can be connected using a quick link, carabiner, shackle, or clevis.The load can be transferred from a chain to another object by a chain stopper.
