When was the crossbow invented8/17/2023 ![]() One of the most distinctive Chinese inventions on crossbows was the repeating crossbow (Chu-ko-nu), invented in 2nd Century AD but was used as late as China-Japan war of 1894-1895 by Manchurian troops. By the 200s B.C., the crossbow (nu, 弩) was well developed and quite widely used in China, although there is also some historical and linguistic evidence suggesting its true origins to be in Southeast Asia. ![]() Remains of an ancient Chinese crossbow, 2nd century BCE. This prevents them from snagging on the crossbow nut as they are shot. They also typically only have two fletches per bolt instead of three commonly seen on arrows. Leonardo da Vinci designed many complicated triggers for crossbows, ultimately producing a "hair trigger" that could be shot with very little finger strength.Ĭrossbow bolts are lighter than arrows, but must be sealed with a varnish to ensure their consistent weight. Triggers are known to have been used on crossbows from the early 1400s. The crossbow also includes a trigger, which was later incorporated into rifles, muskets and other firearms. Patternson, whipcord was very common however linen, hemp, and sinew were used as well. The strings for a crossbow are typically made of strong fibers that would not tend to fray. 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. Much as a horse's bridle, it tends to loosen over time, and must be carefully respliced when appropriate. This cording is called the bridle of the crossbow. The prod is attached to the stock with hemp rope, linen, whipcord, or other strong cording. The central European bows were rather exotic as they were constructed of inlays as well as specialized woods. The prod ("bow") and stock of a crossbow were made of good hardwood, such as oak or hard maple. Typically, the nut is at the end of the shelf (also called the bolt rest). 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 cock).
