ABSTRACT:
A bowling ball is returned from the pit area of the bowling alley to the ball storage rack in the approach area of the alley through a pneumatic transfer apparatus and method. The bowling ball is delivered from the pit area to an elongated tube via an inclined track and sucked into the elongated tube where it is accelerated through the tube located under the alley toward the approach area of the alley. As the bowling ball reaches the approach area it is diverted from its travel in the elongated tube and forced into a lift tube which delivers the bowling ball to a ball storage rack in the approach area located above the alley floor. The bowling ball return apparatus makes use of pneumatic techniques and controls the speed of the bowling ball by regulating the fan rotation of an inline motor and fan assembly. The pneumatic bowling ball return apparatus is modified for use with conventional power lift devices used to carry the bowling ball from the subway below the alley floor to the ball storage rack.
