ABSTRACT:
A compound bow includes a riser section, a pair of inner bow limbs cantilevered to respective ends of the riser section, and a pair of outer bow limbs each hingably attached the free standing end of the inner bow limbs. A cam assembly includes a pair of parallel cams attached to opposite sides of the riser section for allowing a pair of camming cables to extend over the edges of the hinged limbs. Each pair of parallel cams are disposed outboard of the width of the riser section to interconnect the bow limbs for lessening the pull force as the drawstring is pulled beyond an intermediate draw length. In a preferred arrangement, the camming cables each extend of the edge of the outer bow limb, and are spaced on either side of the hinged connection between the bow limbs.
