  • Compound archery bow
    Patent number: 5749351

Each bow limb (130) has a tip portion (134) with a let off pulley system (110) connected therebetween. The curvature of each bow limb is enhanced to reduce the amount of deflection of the pair of bow limbs along a path parallel to the flight path of an arrow shot from the bow.
