Abstract: A ball throwing machine which includes a pair of rotary discs supported for rotation and angularly opposed relation so as to laterally engage a ball and effect propulsion thereof is disclosed. A pair of positioning disc disposed on the interior ball-contacting surfaces of the flat-faced rotary disc precisely locate the balls to be projected on the rotary discs to insure consistency between throws or pitches.

Abstract: Ball dispensing apparatus for hitting practice includes a ball retainer for retaining and sequentially delivering balls to one end thereof, a lever rotatably mounted on a shaft at the one end of the retainer for engaging and lifting a ball from the retainer upon rotation of the lever, and an actuator for the lever for causing the lever to engage, lift, and project a ball from the retainer. A spring is attached to the retainer and to the shaft for accelerating the rotation of the lever into engagement with the ball. The tension of the spring can be varied thereby varying the trajectory of a ball lifted from the retainer.
