  • Air-operated rudder assembly for a bowling pin setter
    Patent number: 5709608
    Abstract: A mechanism for air-assisted rudder operation that supplements current rudder assemblies involved in returning bowling balls to the bowler. An electric motor rotating a cam activates and deactivates an air switch which in turn operates an air cylinder causing the rudder of a bowling machine to oscillate. The oscillation prevents bowling pins from entering the ball lift area.
