20090023508 | Bowling Ball With Weight Block - 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. | 01-22-2009 |
