ABSTRACT:
An automatic ball serving apparatus for serving tennis balls for practice purposes. Balls which are loaded into a feed container are passed through a main bucket and fired through a firing barrel by compressed air. A pair of motors oscillate the firing barrel independently in both horizontal and vertical directions so that balls will be fired having random trajectory, distance and lateral displacement.
