Abstract

A ball throwing machine suitable for battery operation is disclosed. Balls are supplied from a helical ball track to a firing track. A ball striker is cocked by a motor against the force of an adjustable spring. When the striker is positioned over-center the striker rapidly rotates striking the ball. A one-way clutch mechanism is included in the gear train between the motor and ball striker so that the kinetic energy remaining after the ball is launched is utilized to begin cocking the striker for the next cycle of operation. This results in significant reduction in the electrical energy required to operate the mechanism. An elevation control permits selective positioning of the firing track relative to the ball striker.
