Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 229 words
The method of constructing a bowling ball to have preselected performance characteristics for a bowler having a predetermined ball delivery style, the ball having a center of gravity marker on its surface, that comprises: implanting an unbalancing weight into the ball near its outer surface on a radial axis of the ball which makes an angle of the general order of 67.degree. with a radial axis substantially intersecting the center of gravity of the ball, determining the ball track of the bowler in relation to the center line of the thumb and finger holes of a ball he has used, such center line intersecting the center of gravity of the ball, and said thumb and finger holes lying on opposite sides of the center of gravity marker, thereby establishing an individual V-pattern for the bowler, one leg of which represents the bowler''s ball track line, and the other leg of which represents the thumb and finger hole center line, transporting this Vpattern to the new ball and orienting it such that the ball track line thereof is at a selected angle to a circumferential line from the center of gravity marker to the implanted unbalancing weight, marking the thumb and finger hole center line of the thus oriented V-pattern on the new ball, and drilling the thumb and finger holes using this marked-on line as the center line thereof.
