ABSTRACT:
An improved device useful for hurling baseballs or the like to players in practice ball-hitting sessions has been developed. It provides multi-directional spin control to make a ball curve in any chosen direction from a normal trajectory path, as well as speed control, and it can be carried as a substantially lighter-weight and more easily portable package than the massive and expensive electric-powered curve-ball hurlers such as are now used by professional teams. The spin control is provided by attaching one end of a strap to the ball-holding pouch of an elastic-powered slingshot, or catapult, such that the loose end of the strap may be wrapped in any chosen direction around the ball as it is nested into the pouch, and the strap will induce a spinning motion on the ball when it flies out. The speed control is provided by a light-weight flexible cord that limits the length to which the elastic members of a slingshot may be stretched back; variable settings are possible. Weight reduction and easy portability is further improved by having a relatively thin and flat framework designed to hold the forward ends of the elastic members in a spaced-apart and elevated position, and having one or more relatively light-weight guy lines reaching forward from the framework to one or more suitable anchor points, such as stakes driven into the ground. The guy line(s) works in tension to resist the pull on the elastic members and hold the framework in a near vertical position.
