Abstract: The invention defines alternate means of increasing mechanical advantage in asynchronous compound bows of a type generally defined in U.S. Pat. No. 6,470,870, which employ dual planar compound pulleys as the primary leverage inducing agent, and at least one non-coplanar actuator section rigging. Additional pulley elements are added to the primary limb, or PRES member extension, or both, in a variety of possible configurations, in a manner that provides greater leverage than would be present in prior art asynchronous compound bows of the type defined generally by U.S. Pat. No. 6,470,870.

Abstract: An improved arrow shaft comprised of a core of substantially round, very lightweight, porous material, with the porous core having sections that have different diameters at various points along the length of the arrow shaft, with the lightweight core materials being overwrapped with different thickness' of reinforcing materials such that the resulting outside diameter of the finished arrow shaft has substantially parallel surfaces over the entire length of the shaft and the finished shaft has a substantially constant circumference and outside diameter along its entire length.

Abstract: An archers bow comprising a center riser section, two primary resilient limbs, a pair of twin grooved, dual-planar compound pulleys, with the compound pulleys being employed in a multiple of possible ways with non-coplanar actuator elements for purposes of inducing mechanical advantage, with the mechanical advantage induced by the pulleys being used by the archer to aid in bending the limbs on the bow in a manner which eliminates pulley/actuator induced torsion from the system. The invention defines an actuator configuration for the pulleys consisting of one or more sections, including tensioning actuator sections and one actuator section that is suitable for use as a bowstring, and includes a method for connecting the tensioning actuators to the pulleys, and to terminating locations on a pair of resilient Pulley Return Energy Storage e.g.
