Bowling ball with core having low density roll blocks

Abstract

A bowling ball is disclosed with a core having low density roll blocks or end caps which lowers the differential radius of gyration and lowers the maximum radius of gyration of the ball in order to create a different ball path from the foul line to the pins. When the bowling ball core of the present invention is used within a bowling ball it results in a bowling ball that rolls earlier on the lane for a smooth, curving ball path and less angle change in the backend of the lane.

I claim:  
     
         1 . A bowling ball comprising: 
 a bowling ball core body;    a coverstock surrounding said bowling ball core body;    at least one end cap attached to said bowling ball core body wherein said end cap is of a lower density than said coverstock;    whereby said bowling ball core body with attached at least one end cap allows said bowling ball to create an earlier curving motion than traditional bowling balls.    
     
     
         2 . The bowling ball of  claim 1  wherein said bowling ball core with attached at least one end cap lowers the maximum radius of gyration of said bowling ball.  
     
     
         3 . The bowling ball of  claim 2  wherein said at least one end cap is located with its outer surface from ¼ to 1½ inches from the outer surface of said bowling ball.  
     
     
         4 . The bowling ball of  claim 3  wherein said bowling ball core with attached at least one end cap lowers the differential radius of gyration of said bowling ball.  
     
     
         5 . The bowling ball of  claim 4  wherein said bowling ball has a radius of gyration not to exceed 2.800 inches.  
     
     
         6 . The bowling ball of  claim 5  wherein said at least one end cap allows said bowling ball to hook sooner in oil with less angle change on the backend.
