Bowling ball

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.

What is claimed is: 
     
       1. A bowling ball consisting essentially of: a) a solid body having a substantially spherical outer surface and a first homogenous density;   b) said body including one or more concentric layers, the inner most of said layers being a solid sphere and any other layers being of substantially constant thickness, surrounding and contacting the next inner layer, each of said layers being of predetermined homogenous density; and   c) a single, elongated weight member integrally positioned within and entirely surrounded by said body, said weight member being substantially symmetrical about a central, linear axis and having first and second terminal ends, a maximum cross-section at an intermediate axial position between said first and second ends, a .[.second homogeneous.]. density substantially greater than said first homogenous density and said predetermined homogenous density, an inward taper extending over at least a portion of its length from said intermediate axial position to each of said first and second ends, and a non-circular cross-section in all planes parallel to said linear axis.   
     
     
       2. The invention according to clam 1 wherein said ball has a center of gravity offset from the geometric center of said ball. 
     
     
       3. The invention according to clam 1 wherein said ball has a center of gravity coincident with the geometric center of said ball. 
     
     
       4. The invention according to claim 1 wherein said first and second ends are equidistant from said intermediate axial position. 
     
     
       5. The invention according to claim wherein one of said first and second terminal ends is positioned closer to said intermediate axial position than the other of said first and second ends. 
     
     
       6. The invention according to claim 1 wherein said weight member is of polygonal cross-section in all planes transverse to said linear axis. 
     
     
       7. The invention according to clam 1 wherein said weight member tapers uniformly from said intermediate axial position to each of said first and second ends. 
     
     
       8. The invention according to claim 1 wherein said body includes at least one blind grip hole extending from said outer surface into said body. .Iadd. 
     
     
       9.  The invention according to claim 1 wherein said weight member's density is homogenous throughout..Iaddend.
