ABSTRACT:
An archery bow having a handle, an inner pair of bow limbs projecting outwardly from opposite ends of the handle and an outer pair of bow limbs projecting outwardly from opposite ends of the handle. A cable is connected to ends of the inner bow limbs and through the handle via a pulley system. A cocking mechanism is attached to an end of the cable and is mounted at an end of one of the inner bow limbs for enabling the archer to increase tension on the cable whereby the inner bow limbs are stressed and placed in a cocked position. A release mechanism is mounted at an end of one of the outer bow limbs. When the archer draws and releases the bow string extending between the outer limbs, the release mechanism triggers the cocking mechanism to release the inner bow limbs which act in cooperation with the outer bow limbs whereby increased thrust is imparted to the arrow.
