Abstract
A ball spinning device which has one or more balls, each ball having the surface appearance of a baseball. For an embodiment that has more than one ball, all balls are positioned in a straight line by connecting spindles. A power transferring spindle is sized and shaped so it can be connected to an electric motor which is capable of spinning the device at the same speeds as those of pitched baseballs. For each ball, its axis of rotation relative to its seam is determined by where spindles are joined to the ball with respect to its seam.
Claims12
A device rotated by an electric motor, to enable someone to practice recognizing types of spins common on pitched balls, but without having to pitch balls, said device comprising in combination:
- a. a plurality of balls, each ball having the surface appearance of a seamed ball that is typically pitched, each said ball being no larger than the size of a seamed ball which is typically pitched and each said ball made of materials lightweight enough to prevent visible bending of the spindles when said device is operated with its spindles held horizontally,
- b. a power transferring spindle, joined to the one of said balls that is nearest an electric motor when said device is operated, and said power transferring spindle sized and shaped so that it can be connected to an electric motor,
- c. connecting spindles, numbering one less than the number of said balls, each said connecting spindle joined to two said balls with no said ball joined to more than two said connecting spindles, and
- d. joining means for spinning said balls and the spindles together as only one unit and
- all the spindles are straight and are inconspicuous and are positioned along an axis of rotation going through the centers of all said balls, and wherein all the spindles meeting said balls' surfaces at locations that are specific and intended in relation to said balls' seams.

- b. a power transferring spindle which is straight and which is inconspicuous and which is positioned along an axis of rotation passing through the center of said ball, said power transferring spindle sized and shaped so that it can be connected to an electric motor,
- c. joining means for spinning said ball and said power transferring spindle together as only one unit, and
- d. said power transferring spindle meeting said ball's surface at a location that is specific and intended in relation to said ball's seams.
