Abstract
An air suspension batting tee apparatus which includes an air blower for providing a moving air column which supports a spherical object, a conduit terminating at a nozzle for directing the air column, and an oscillator for producing a fluctuation in the flow of the air column through the nozzle. A ball suspended in the air column may be made to oscillate vertically. An air flow displacement arm may be used to produce oscillating movement of a suspended object in a cylindrical path around a vertical axis, thereby simulating motion of a curve ball or a screw ball. The nozzle may be adjusted to varying heights to place a suspended ball within a strike zone for varying sized batters.
