ABSTRACT:
A bowling ball having an outer shell and a core comprised of a main body and a plurality of weight blocks. The outer shell is of uniform thickness, completely encases the core and has an outer spherical surface. The main body and the weight blocks combine to form a solid sphere. The weight blocks are of the same size, shape and material and have first curved surfaces which form a part of the outer surface of the core and second surfaces directed to the center of the sphere. The weight blocks are symmetrical about center axes thereof and have a greater density than the main body. The first and second surfaces of the weight blocks join at an edge. The weight blocks diminish in cross section, transverse to their center axes, from the edges to the lowermost portions. The weight blocks form a cluster around a vertical axis extending outward from the geometric center of the ball. The center of gravity of the cluster of weight blocks and of each individual weight block is an equal distance from the geometric center of the ball. In other embodiments of this invention, the ball is comprised of a homogeneous material (except for the weight blocks) without an outer shell. The weight blocks are embedded with the ball and are designed as discussed above.
