Abstract
Abstract A ball-tossing device is disclosed that has a batting practice member that is mechanically coupled to a foot treadle plate that is pivoted on a base member. The arrangement is such that pressure on the foot treadle plate spring-loads the ball-tossing member, and continued movement of the foot treadle plate causes the ball-tossing member to quickly move the ball in an upward direction. A spring means is provided to return the foot treadle plate to a normal rest position that in turn, returns the ball-tossing member to a rest position.
