ABSTRACT:
A mechanism for air assisted ball-lift that supplements current ball elevator mechanisms used to return bowling balls to the bowler. When the bowling ball is gravity fed onto the top pad, the trigger is depressed causing the mechanism to raise. The bowling ball is moved vertically by the use of an air cylinder in order to positively engage the ball elevator mechanism.
