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.

Claims

1. Ball dispensing apparatus comprising a ball retainer for retaining and sequentially delivering balls to one end thereof, said ball retainer gravitationally feeding balls to said one end, said one end having a stop for limiting travel of a ball in said retainer,

a rotatably mounted lever mounted on a first shaft at said one end for engaging and lifting a ball from said retainer upon rotation of said lever,

actuator means for said rotatably mounted lever for causing said lever to engage, lift, and project a ball from said retainer, said actuator means comprising a motor having a drive shaft, said first shaft being coupled to said drive shaft, and spring means attached to said first shaft for accelerating said lever into engagement with a ball, said spring means being adjustable in tension to vary the projection of a ball by said lever with one end of said spring means being adjustably attached to said ball retainer and the other end of said spring means attached to said first shaft, and

a vertically adjustable mount for supporting said ball retainer, said ball retainer being rotatable on said mount whereby direction of balls to a hitter can be varied by swiveling said ball retainer.

2. The ball dispensing apparatus as defined by claim 1 wherein said retainer comprises a plurality of rods configured to receive and gravitationally feed balls.

3. The ball dispensing apparatus as defined by claim 1 wherein said drive shaft includes a gear assembly for reducing the speed of said motor, said gear assembly including a crank and pin for engaging a thrust pin extending from said first shaft.

4. The ball dispensing apparatus as defined by claim 1 wherein said ball retainer includes a bracket having a plurality of slots, said spring means engaging one of said slots to vary spring tension and alter the trajectory of a projected ball.

5. The ball dispensing apparatus as defined by claim 1 and further including bracket means at said one end for receiving a ball for delivery to a pitching machine.

6. The ball dispensing apparatus as defined by claim 1 wherein said ball retainer includes a vertical support rod, said vertically adjustable mount further including a support stand for receiving said support rod.

7. The ball dispensing apparatus as defined by claim 6 and further including collar means on said support rod for engaging said support stand and permitting the swiveling of said ball retainer on said support stand.
