ABSTRACT:
A novel critical supplementary apparatus, when used in conjuction with U.S. Pat. No. 6,533,673, collectively completes the sphere of practical operation of a convexo-concave bowling ball retrieving device that captures, guides, lifts and deposits in one smooth continuous flowing motion a bowling ball for subsequent discharge into a bowling ball return. U.S. Pat. No. 6,533,673 addresses the inherent lack of friction problems found in Brunswick automatic pinsetter bowling machines, models A and A2 but is unable to comply with a similar problematic lack of friction situation found in the remainder of Brunswick product line—models Factory A2 and the Jetback. The models Factory A2 and Jetback don't have adaquite clearance between the bowling ball retrieving device1that is mounted on the rotating ball return wheel6(as disclosed in U.S. Pat. No. 6,533,673) and the 1 HP motor mount shaft19. This critical adapter device18circumvents this clearance obstacle by allowing for an abrupt change in the linear profile of the 1 HP motor mount shaft19.
