Lever Lever A lever ( or ) is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum. A lever is a rigid body capable of rotating on a point on itself. On the basis of the location of fulcrum, load and effort, the lever is divided into three types. It is one of the six simple machines identified by Renaissance scientists. A lever amplifies an input force to provide a greater output force, which is said to provide leverage. The ratio of the output force to the input force is the mechanical advantage
Lever action the development of its popular hammerless Models 1895 and 1899 (which became named the Model 99) lever-action sporting rifles. The Models 1899/99 were produced from introduction in 1899 until the expense of producing the rifle, and declining interest in lever-action rifles from the 1950s on, resulted in dropping the Model 99 from production in 2000. Unlike most Winchester and the Marlin lever-action rifles, which used a tubular magazine requiring round-nose or flat-nose bullets, Arthur Savage designed his rifle using a rotary magazine. This allowed the 99 to use cartridges with spitzer pointed bullets for increased ballistic performance. The 99 was
