ABSTRACT:
An archery bow having limbs of adjustable resilient force with the draw poundage force necessary to maintain the bowstring at full draw being substantially less than conventional compound bows and with the propelling force on the arrow increasing substantially uniformly from a minimum at full draw to a maximum at the point immediately preceding free arrow flight. The resilient limbs flex in a direction away from the archer and have pivotally mounted force multiplying mechanisms at their ends interconnected by non-yieldable cables to the bow handle.
