The string catch (nut) is shaped like a 'J' because it usually has a tall erect rear spine that protrudes above the housing, which serves the function of both a cocking lever (by pushing the drawn string onto it) and a primitive rear sight. The entire mechanism is then dropped into a carved slot within the tiller and secured together by two bronze rods. The Chinese trigger was a mechanism typically composed of three cast bronze pieces housed inside a hollow bronze enclosure. Medieval European crossbow nut mechanism:ġ6th century crossbow nut excavated at Harburger Schloßstraße, Hamburg-Harburg, GermanyĪ crossbow is essentially a bow mounted on an elongated frame (called a tiller or stock) with a built-in mechanism that holds the drawn bow string, as well as a trigger mechanism, which is used to release the string. Construction Qin and Western Han dynasty crossbow trigger pieces. The lock refers to the release mechanism, including the string, sears, trigger lever, and housing. The stock is the wooden body on which the bow is mounted, although the medieval tiller is also used. Peterson, the prod came into usage in the 19th century as a result of mistranslating rodd in a 16th-century list of crossbow effects. The lath, also called the prod, is the bow of the crossbow. Īrrow, bolt, and quarrel are all suitable terms for crossbow projectiles. The last two are also used to refer to the crossbow. Terminology Ī crossbowman or crossbow-maker is sometimes called an arbalista, arbalist, or arbalest. In modern times, firearms have largely supplanted bows and crossbows as weapons of war, but crossbows remain widely used for competitive shooting sports and hunting, and for relatively silent shooting. The medieval European crossbow was called by many names, including 'crossbow' itself most of these names derived from the word ballista, an ancient Greek torsion siege engine similar in appearance but different in design principle. Crossbows brought about a major shift in the role of projectile weaponry in wars, such as during Qin's unification wars and later the Han campaigns against northern nomads and western states. The earliest known crossbows were made in the first millennium BC, as early as the 7th century BC in ancient China during the Spring and Autumn period(770-478 BCE) and Warring States period(475-221 BCE), and as early as the 1st century AD in Greece (as the gastraphetes). Crossbows are usually drawn by direct pulling, but windlass-like mechanisms requiring less force were sometimes used. This enables a crossbowman to handle more draw weight, and to hold it with significantly less physical strain, thus potentially achieving better precision and enabling their effective use by less-skilled personnel. A crossbow has a locking mechanism to maintain the draw, limiting the shooter's exertion to pulling the string into the lock and then releasing the shot by depressing a trigger. Ĭrossbows and bows use the same launch principle, but an archer using a longbow must maintain its draw by pitching the bowstring with fingers, pulling it back with arm and back muscles, and then holding that form while aiming, which demands significant physical strength. A person who shoots crossbow is called a crossbowman or an arbalist (after the arbalest, a European crossbow variant used during the 12th century). Crossbows shoot arrow-like projectiles called bolts or quarrels. 21st-century hunting compound crossbowĪ crossbow is a ranged weapon using an elastic launching device consisting of a bow-like assembly called a prod, mounted horizontally on a main frame called a tiller, which is hand-held in a similar fashion to the stock of a long gun.
