Filed:

7/525678

Abstract:
A pitching machine for simulating the high speed, underhand delivered pitch used in fast pitch softball. An electric motor drives an arm on a 360. degree. vertical path of travel. A lost motion coupling between the motor and the arm permits a spring drive during a portion of each arm revolution. The arm is connected to a torsion spring so that energy stored in the spring drives the arm during a portion of each revolution at a high rate of speed to propel the ball from the pitching unit by centrifugal motion as the arm approaches the bottom of its path of travel. A shroud in the form of a cup-shaped cage open at one end cooperates with a curved member to hold the ball until the release point is reached. An optional spring biased, toothed, pivoted lever adjacent the shroud discharge opening frictionally engages the ball to cause a trajectory altering spin to the ball as it is propelled from the unit. A plunger operated ball supply ramp delivers the balls, one at a time, to a station for automatic pickup by the arm during each machine cycle.
