Abstract: A bowling ball having an asymmetrical weight block with respect to its central axis. The weight block has a pair of ends through which the central axis of the block extends, and a medial portion which is offset or skewed with respect to the weight block axis. The block has an outer surface which has a maximum cross section in at least one plane intersected by the central axis intermediate of the two ends. The plane is intersected by the central axis and is enclosed by a boundary defining the largest transverse cross section of the block not normal to the central axis. The medial plane is disposed at an angle of between about 22.5° and 90° with respect to the central axis of the block.

Abstract: A bowling ball having an elongated weight member integrally incorporated therein for enhancing the ball's inherent, angular momentum as it travels down a lane. The weight member has a longitudinal axis with a maximum cross-section at an intermediate axial position, and an inward, uniform taper extending from this intermediate axial position towards opposite, terminal ends. When the ball is released with the axis of the weight member in a predetermined orientation with respect to the bowler's track, as determined by the position of the grip hole(s) relative to the weight block, pin action is enhanced thereby producing consistently higher scores.
