Appeal No. 1999-0515 Page 4
Application No. 08/620,256
The objective of the appellant’s invention is to teach
batters to recognize the various spins that are placed on
thrown baseballs by pitchers, such as fastballs, curveballs,
and sliders, without actually pitching the ball. This is
accomplished by attaching a ball device to an electric drill in
a manner that imparts the various spins to the ball so they can
be visualized by a potential batter, and the invention is
directed to such a ball device.
