Abstract
An archery bow design in which a pair of flexible limbs are secured on opposite ends of a riser that defines a hand grip or handle, and wherein recoil assemblies at opposite ends of the riser are connected with a bow string to bias the string in a first direction for propelling an arrow. In one form of the invention, a recoil cable extends from the free end of each limb to a cam at the opposite end of the riser, and the cam is connected for rotation with a take-up spool for storing cable. The bow string is connected with the take-up spool, whereby the take-up spool is rotated when the bow string is drawn, thereby rotating the cam and deflecting the limb to store energy for propelling an arrow. In another form of the invention, the recoil cables are omitted and flat wound coil springs are connected with the cam so that when the bow string is drawn the flat wound coil springs store energy. The cam provides a let-off feature whereby a relatively small force is required to draw the bow and hold it in a fully drawn position, and a relatively higher recoil velocity is obtained when the string is released.
