ABSTRACT:
A bowling ball weight block consists of body, tip and head portions, the tip and head portions being located on opposed ends of the body. The body portion is in the form of a cylinder or parallelepiped, the head is in the form of a spherical segment or frustum of a pyramid, and the tip is in the form of a frustum of a pyramid, or cone. The head and tip portions are chosen such that the mass of the tip is not greater than the mass of the head. By utilizing different masses and/or dimensions for the head and tip portions, an asymmetrical weight distribution about the roll axis of the ball can be developed. The weight block exhibits distinct roll characteristics depending on whether it is positioned within a ball in a head-up or tip-up orientation with respect to the ball label.
