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.
Claims1
In combination with an automatic pinsetter of the type having an oscillating rudder, an air-operated rudder assembly comprising a substrate having a motor assembly which operates a cam, said cam contacting an air switch to activate said assembly, air lines connecting said air switch to an air cylinder which has a mounting means at one end and a means for mounting another end to said rudder whereby said assembly produces oscillating lateral energy to the rudder arm with a more than one second delay to facilitate bowling pin removal and bowling ball access in the elevator area.
