Abstract

934,839. Ball projectors. E. J. POLITZER. Dec. 27, 1961 [Jan. 6, 1961], No. 46268/61. Class 132 (2). An automatic ball throwing device for practising games, such as tennis, comprises a ball throwing tube and magazine, means for varying the striking force on the ball ejector, means regulating the frequency of the ejections, and means slidably and pivotally mounted on two axes at right angles to each other to control departure position and the slope and orientation of the throwing trajectory. The balls are ejected by a spring-loaded piston 8, the intensity of the striking force being manually adjustable by a screw cap 14. A number of balls are loaded into a hopper 15 for automatic successive firing under the control of a cam 25 which is rotated by a motor-reducer unit 28 to recock the piston 8 in co-operation with a latch 36. After the initial switching on by a player, the rate of firing is controlled by one or other of a bank of bimetallic switches 39. The apparatus is mounted for vertical and horizontal movement on an adjustable vertical shaft 42 to enable the height and direction of ejection to be controlled, and tiltable on a horizontal axis to enable the elevation of firing to be adjusted.
