  • Patent number: 4364371
    Abstract: A ball throwing implement (10) is disclosed which includes a flexible shaft (12) having at one end a threaded portion (16) on which a stop disk (18) is movably mounted. A ball or similar game element (20) having a diametral bore (22) is slipped over the end of the flexible shaft into position against the stop disk. On the other side of the ball from the stop disk, a resilient release element is incorporated in the shaft so that it bears against the wall of the diametral bore. By moving the stop disk to adjust the extent of engagement of the diametral bore with the release element, the force required to throw the ball from the shaft may be adjusted.
