Abstract
An archery bow having a riser capable of being gripped by an archer from which is centilevered upper and lower spring members. Bow limbs are pivotably suspended from the free end of each spring member at the midsection thereof so that each limb hangs on the archer's side of the bow. A bow string is attached to upwardly extended tips of the limbs. Cams, which are rotatably supported from the top and bottom sections of the riser, are connected to the lower portion of each limb by means of a control cable that is reeved to the working profile of the cam. One end of the control cable is secured to the base of the associated limb while the opposite end is secured to the limb's midsection to hold the control cable taut against the working surface of the associated cam. Accordingly, as the bow is drawn, the pull weight delivered to the bow string is controlled by the cam system to provide maximum pull weight at an intermediate draw position.
