CrossbowA crossbow is a weapon that fires projectiles called crossbow bolts or quarrels. invented in China, the crossbow played a significant role in European medieval warfare and is still used today. DescriptionA crossbow consists of a prod (similar in appearance to a bow) mounted on a stock similar to a rifle stock, which has a mechanism to wind and shoot its bolts. These bolts are typically called quarrels, and do not depend upon lift as arrows do. The stock and trigger of hand-held firearms may have been copied from crossbows. Crossbow bolts must be made to have consistent weights as the mechanical process of engaging a bolt forces a more uniform process than that of using a bow and arrow. This consistent performance was part of what made the crossbow historically a significant force in warfare. A crossbow contains a string which is held in place by a nut when the bolt is loaded and the cross bow is engaged (referred to as at full draw). Typically, the nut is at the end of the shelf (also called the bolt rest). The prod ("bow") and stock of a crossbow were made of good hardwood, such as oak or hard maple. The central European bows were rather exotic as they were constructed of inlays as well as specialized woods. The prod (also called lath in England) is attached to the stock with hemp rope, linen, whipcord, or other strong cording. This cording is called the bridle of the crossbow. Much as a horse's bridle, it tends to loosen over time, and must be carefully respliced when appropriate. The prod is very short compared to bows, thus resulting in a short draw length. This makes crossbows inefficient at storing energy, which is why they must have very heavy draw weights. The draw weight of a modern crossbow can be up to 300lbs. The crossbow shelf is a flat section above the stock with a straight groove for the bolt to rest upon and travel along as it is shot. The strings for a crossbow are typically made of strong fibers that would not tend to fray. According to W. F. Patternson, whipcord was very common; however linen, hemp, and sinew were used as well. Even cotton was tried with some success. In wet, twisted mulberry root was occasionally used. The crossbow also includes a trigger, which was later incorporated into rifles, muskets and other firearms. Triggers are known to have been used on crossbows from the early 1400s. Leonardo da Vinci designed many complicated triggers for crossbows, ultimately producing a "hair trigger" that could be shot with very little finger strength. Crossbow bolts are lighter than arrows, but must be sealed with a varnish to ensure their consistent weight. They also typically only have two fletches per bolt instead of three commonly seen on arrows. This prevents them from snagging on the crossbow nut as they are shot. HistoryRemains of an ancient Chinese crossbow, 2nd century BCE.By the 200s BC, the crossbow (nǔ, 弩) was well developed and quite widely used in China[1]. Crossbows have been found among the soldiers of the Terracotta Army in the tomb of emperor Qin Shi Huang (260-210 BCE) [2]. Some linguistic evidence also seems to indicate a Southeast Asian origin [3]. One of the most distinctive Chinese inventions on crossbows was the repeating crossbow (Chu-ko-nu), invented in 2nd Century AD which was used as late as China-Japan war of 1894-1895 by Manchurian troops. Roman bows tended to be ornate and well engineered, yet western European bowstocks that were produced 600 years later appeared to be nothing more than rough hewn slabs of wood. The prod of a crossbow was made of wood or composite materials until the middle of the 15th century. The advantage of a simple wooden prod is that the bow as a whole was lighter in weight, easier to span (even by hand), and quicker to discharge. Composite prods were made of horn, sinew and wood, and produced much larger draw forces. The draw force is the tension that the string is under when the bow is engaged. Since the draw force can be much more than a soldier might be able to pull, these crossbows generally include a winch device to cock them. It is the high launch force of a crossbow that made it a formidable weapon in warfare. Since composite prods involved gluing material together which would have to withstand a great deal of stress, a slow drying time was essential. The strongest glues naturally took longer to dry. It was not uncommon for six months up to a year to be spent in ensuring a bow was dried properly. In the later 1400s, steel manufacturing advanced significantly, and was more commonly used in spring production. A crossbow prod was made out of spring steel, steel prods being very common by the early 1500s as their performance was more uniform, except in very cold weather. About 1400 the use of the crossbow changed, with the butt end of the stock being placed on the shoulder for accuracy. By 1650, the cross bow looked like it had a rifle stock, and was used in a similar way (what you see on a rifle has probably already been done on a crossbow). Makers of crossbows (arbalistmeisters) were making quite beautiful crossbow stocks by 1600. Some Belgian designs were as polished as those of modern Olympic rifles. UseCrossbows were actively being used in European warfare from 800 to 1500 A.D. They supplanted bows in many European armies for a number of reasons. An expertly handled longbow had greater range, better accuracy (the "arbalest" or siege crossbow being the exception here), and a much faster rate of fire than an average crossbow, but the value of the crossbow came in its simplicity: it could be used effectively after a week of training, while a comparable single-shot skill with a longbow could take years. The use of winches allowed soldiers to use and fire weapons with a draw force far in excess of what they could have handled with a bow. In the later years of the crossbow it had enough kinetic energy to penetrate the armor of a knight with ease: some reached a draw force of nearly 350 lbf (1600 N), compared to the 60-180lbf (300-900 N) draw force for a longbow. Moreover, crossbows could be kept cocked and ready to shoot for some time with little effort, allowing crossbowmen to aim better and to "cover" a target area, while archers could not keep their powerful bows pulled for long periods of time. Due to the long time required to reload a crossbow, users would sometimes make use of a pavise. Pope Urban II banned the use of crossbow against Christians in 1097, and the Second Lateran Council did the same for arbalests in 1139. The crossbow was seen as unchivalrous and as a threat to social order, since a peasant could kill a noble anonymously; crossbow mercenaries were usually killed immediately on capture, unlike others who might have been ransomed or set free. However, their effectiveness made them an "evil" no one could afford to be without, often in the form of hired foreign mercenaries. Given the great accuracy of the crossbow, it filled many duties that sniper rifles have today. Crossbows were eventually replaced in warfare by gunpowder weapons. Early guns had slower rates of fire and much worse accuracy than contemporary crossbows. Modern crossbows are still used for target shooting and in some places for hunting. They are made of the same composite materials as modern bows. One of the newest developments in crossbow technology is the use of the shoulder-cock. The shoulder-cock is extremely easy to use and has a fast loading time. Using a shoulder-cock, a good crossbowman could reload in under 7 seconds. The average draw force for the shoulder-cock crossbow is 100 lbf (400 N), which is low compared to other crossbows. A good example of a shoulder-cock crossbow is the FX-II crossbow.
