Abstract: The present invention is a pitching machine for use in batting and fielding practice for baseball and softball. The pitching machine of the present invention uses an expanding gas to propel a ball down a barrel toward the intended target. While the expanding gas could be created by a variety of means without departing from the scope of the present invention, including a piston, ignition of a combustible fuel, or a chemical reaction, the preferred embodiment of the present invention uses compressed air in a reservoir.

Abstract: A projectile substance is pneumatically propelled. The projection substance is inserted onto a longitudinal bore of a barrel and a rupture disk is attached to a first end of the barrel. Next, the first end of the barrel is coupled to a first end of a pneumatic reservoir having a chamber therein. The rupture disk, as attached, acts to form a seal between the longitudinal bore and the chamber.

When the disk ruptures, the gas in the chamber rushes into the longitudinal bore with sufficient force to propel the projectile substance out of the barrel. One or more pistons may be slidably disposed within the chamber to form more than one chamber portion. An average pressure for propelling the projectile substance may be increased by various methods of forcing the piston(s) toward the projectile substance as it is being driven out of the barrel.
