A bowling alley return mechanism includes a horizontal ball return disposed between two adjacent lanes, a pair of side walls which define a chamber and a ball door or opening in one of the side walls. A generally crescent-shaped concave pivotally mounted cradle is disposed within the chamber and adjacent to the opening for receiving a bowling ball thereon. The mechanism also includes an optical sensor which is responsive to a portion of the bowling ball when the bowling ball is on the cradle. A bell crank and linkage rotates the cradle in response to a signal from the sensor. The mechanism also includes an exit door and a releasable locking assembly of the pin and groove type which prevents any flying pins from passing through the exit door. The locking assembly is responsive to an upper portion of a bowling ball when the ball is moved by the cradle to unlock the exit door and allow the ball to pass therethrough and into the horizontal ball return for propulsion to the opposite end of the alley. In addition the mechanism includes an oscillating paddle for removing pins from the chamber and for preventing more than one ball from entering the chamber at the same time.
