A throwing arm is rotatably mounted on the support for throwing targets. Structure is provided for eccentrically swinging the support back and forth while throwing targets. A mechanism is connected within a first eccentric drive connection and is operative in response to movement of the first eccentric drive for superimposing an eccentric series of short back and forth swings on the support during each long swing of the support. A second eccentric drive transmits eccentric motion to the support through a member that is movable with respect to the guide mechanism.
