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.
An archery bow including
An archery bow including a riser that is adapted to be grasped by an archer having upper and lower spring members cantilevered from the top and bottom surfaces of said riser, upper and lower cams rotatably supported at the top and bottom of the riser, a limb pivotably mounted about its midsection upon the terminal end of each of said spring members, a control cable reeved about each of said cams and being secured at both ends to an adjacent one of said limbs, said ends of the cable being spaced apart along the length of the limb, and a bow string connected between the outer tips of the limbs whereby application of a drawing force upon said bow string causes the cables to rotate the cams thereby imparting a programed motion to said limbs.
