Abstract
A bow comprises: a riser; first and second limbs attached to the riser; first and second pulley members rotatably connected to the respective bow limbs; draw, power, and tensioning cables; and a tensioning pulley. The draw cable engages draw cable journals of the pulley members and rotates them as the bow is drawn and the draw cable is let out from the draw cable journals. The tensioning cable is secured at its first end to the first bow limb and engaged at its second end to be taken up by a power cam of the first pulley member as the bow is drawn and the first pulley member rotates. The tensioning pulley includes a tensioning cable journal and is arranged with the tensioning cable engaged therewith. The power cable is connected at its first end to the tensioning pulley and at its second end to the second bow limb.
