Abstract
A compound archery bow with a handle-providing rigid riser and flexible limbs on the riser mounting bow string pulleys has damping interconnection mechanism between the limbs and riser. A damper is carried by each riser inboard of a riser limb seat. A resilient limb cup for each limb seat has portions for engaging the bottom, side walls and inner end wall of a limb and a fastener extends from each limb through each limb cup and limb seat to secure the limb to the damper.

5. In a compound archery bow comprising a handle-providing rigid riser with opposite ends, flexible limbs having inner ends secured to the riser and outer ends mounting bow string accommodating revolvable members, and a vertically extending bow string trained around said members, the improvement wherein:
-
(a) said riser has opposite ends and a limb seat is provide on each of said riser opposite ends, each said limb seat having a bottom wall, upstanding side walls, and an upstanding end wall opposite an opposed open end for receiving said inner end of one of said limbs;
(b) a limb cup for each of said seats formed of a vibration damping material and having a bottom wall, upstanding side walls, and an upstanding end wall opposite an opposed open end for receiving said inner end of one of said limbs, said cup being received in said limb seat with said cup end wall adjacent said seat end wall and said side walls adjacent said side walls of said seat;
(c) the inner end of each limb having an end wall and side walls and being received in said limb cup with its end wall adjacent said limb cup end wall and said limb side walls adjacent said cup side walls; and
(d) a fastener assembly extending through said limb, cup, and seat at each end of said riser to secure said limb inner end to said riser at each end thereof. - View Dependent Claims (6, 7, 8, 9, 10, 11)
