Abstract
An archery bow in which there are limbs outwardly extending from a center grip portion, and the cross-sections of the limbs at points along the longitudinal axis of the limbs are of predetermined curved configuration such that on drawing of the bow and decreasing of the radius of curvature of the longitudinal axis of the bow, there will occur at a predetermined rate, increase in the radii of cross-sectional curvature of the limbs. Each bow limb structure has cross-sectional configurations that are curved in its transverse planes which are substantially perpendicular to its longitudinal axis. The configurations have predetermined dimensions of thickness and predetermined dimensions of extent of curvature which progressively vary at different sections of the limb structure. With increase of draw of the limb structures the radius of longitudinal curvature decreases while the radius of curvature of each configuration increases progressively and at different rates at different sections.
