ABSTRACT:
An archery bow having side by side launching and bending bowstrings, the bending bowstring drawn one or more times as a preliminary to firing of the bow to bend the bow limbs, which bent limbs are released only at firing after drawing and releasing both bowstrings, to accelerate an arrow nocked in the launching bowstring. Bending mechanisms are mounted to the bow handle and are operated by the bending bowstring, to wind up a pair of load cables attched to the limb tips onto capstan elements released at firing. A mechanical advantage is achieved in the bending mechanisms to reduce the effort required to bend the limbs by drawing of the bending bowstring.
