elevator, similar to the AMF unit's design. When a ball rolls onto the ball-lift wheel, friction from the cork strips lifts the ball up onto the two lift rods that are covered with a rubber material. When the ball is between the lift rods and the ball wheel it is rolled upward and is dropped onto a metal track that leads the ball to an acceleration belt. The acceleration belt pushes the ball at a fast speed underneath the lanes until the ball is pushed upward by two wheels located at the head of the ball return track, where it is delivered back to the bowlers. When a pin rolls back, the smaller diameter of the pin allows it to fall rearwards through the ball wheel. As the pins are moving from the shaker board, they will bounce around until it lands in a pocket in the pinwheel. The wheel brings the pin to the top and drops it into a metal tray, called a "turnpan", similar to the orientation pan that exists on the rear end of the AMF 82-30 unit's pivoting pin distributor arm. It's shaped somewhat like a scoop, with the lip of the scoop facing the front of the machine. From there a pin elevator lifts the pin up towards the top of the pinsetter, to drop into a rotating metal basket called the "pin turret", letting it slide into one of ten spots as the turret rotates – nine around the periphery in groups of three spots each, and one in the center for the number-5 pin. When a pin lands in an empty location in the turret, the turret rotates (or "indexes") so that the next pin will land in the next empty location, with the 5-pin chute in the center of the turret being filled last. Once the turret is full, and the spotting table reaches the top of its travel, all ten pins are simultaneously dropped from the turret into the spotting chutes of the table's upper level, holding them in the table's upper level as the table lowers them through its full downward travel close to the lanebed, to set the new rack of pins on the pin deck. As the table lowers towards the pindeck to set the new rack of pins, it is visibly protected with its attached sheet metal "deck shield", visible to the bowler at any time
