Title: Trip lever guard means for reel spinning games

Abstract: An auxiliary fraud-deterrent guard method and means for use with handle-operated reel-spinning mechanisms such as poker, fruit and slot machines which employ a trip lever requiring complete, non-retrogressive movement of the operating handle for initiation of a proper operating cycle, wherein retrogression is prevented by a blocking dog which enters behind the advancing trip lever and is automatically displaced to non-obstructing position by the decoupling action of a pawl which frees the trip lever from the handle at trip-out position. An additional feature provides a simple adaptor means mounting the dog for quick installation on existing equipment.
