In modern archery, a compound bow is a bow that uses a levering system, usually of cables and pulleys, to bend the limbs.[1] The compound bow was first developed in 1966 by Holless Wilbur Allen in North Kansas City, Missouri, and a US patent was granted in 1969. Compound bows are widely used in target practice and hunting.
Compound bows are typically constructed of man-made materials such as fiberglass and carbon fiber, while traditional bows and warbows usually are entirely or partially made of wood or bamboo.
The pulley/cam system grants the user a mechanical advantage, and so the limbs of a compound bow are much stiffer than those of a recurve bow or longbow. This rigidity makes the compound bow more energy-efficient than traditional bows, as less energy is dissipated in limb movement. The higher-rigidity, more advanced construction also improves accuracy by reducing the bow's sensitivity to changes in temperature and humidity. In literature of the early 20th century, before the invention of compound bows, composite bows were described as "compound".[2]
