1281799 Table football game apparatus G KAMMERL 23 June 1971 [3 July 1970] 29442/71 Heading A6H Apparatus for playing table football comprises compressed air nozzles 1 pivotable about a vertical axis and arrange at least at the four corners of a playing surface and behind each of the goal structures 3, the nozzles being pivotally directable to propel a ball over the playing surface. Each nozzle is carried on a pistol-shaped handle which includes an electrical trigger contact which closes a control circuit to an electromagnetic valve to trigger off the compressed air. A delay circuit is incorporated in the control circuit to shut off the compressed air nozzle after a predetermined time. When a goal is scored the ball passes through an opening 5 into a ball collector trough at the lowest point of which is arranged an upwardly directed compressed air nozzle which directs the ball up a pipe 7 returning the ball to the playing surface. The goal structure 3 may be provided with electrical contact means connected to a score indicator device. The ball used with the apparatus comprises a spherical shell of lattice-like appearance.
