Abstract
1458037 Ball throwing device J H CHURCH and J NIELSEN 5 Dec 1973 [7 Dec 1972] 56299/73 Heading A6D A device for throwing tennis balls or baseballs comprises a discharge tube 32, a tube 44 arranged to receive balls 40 from a feed device a fan 22 for blowing air through the annular gap 46 between tubes 32 and 44 to induce a ball in tube 44 to move towards the discharge end of tube 32, and a resilient tapered sleeve 42 which arrests the ball until the pressure behind the ball reaches a certain level, whereupon the ball is forcibly propelled through the narrow end of the sleeve and is discharged from tube 32. Fan 22 draws air through inlet 20 and delivers it via flexible hose 26 to chamber 50 and thus annular gap 46. When a ball is arrested in sleeve. 42, the pressure in chamber 52 prevents opening of ball-release flap 56, which is pivoted at 58 and weighted at 60. The rate of pressure build-up behind the ball in sleeve 42 is adjustable by means of knob 72, which controls a valve 64, in turn controlling the amount of communication between chambers 52 and 30; this control of rate of pressure build-up is said to provide control of the balls final ejection speed. When the ball is ejected from the sleeve, the resultant drop in pressure in chamber 52 permits flap 56 to release another ball from tube 54 to tube 44. Second embodiment, Figs. 6-9 (not shown). The cylindrical casing is horizontal instead of vertical. The discharge tube extends from one end of the casing. The ball feed device is lotaled on top of the casing and includes an electric motor-driven linkage which allows only one ball at a time to fall onto the ballrelease flap and controls the rate at which balls are ejected from the device.
