ABSTRACT:
A ball throwing machine which includes a tripod leg support is provided with the rearwardly positioned leg formed as a pair of telescopic sections. Rack and pinion components are mounted one on each leg section and the pinion is operated by a crank to effect lengthening or shortening the telescopic sections, to effect an incremental change in the trajectory of a ball thrown by the machine.
