Abstract: The sports ball catapult driven by mechanical means disclosed herein may comprise a main body, an arming mechanism, a drive mechanism, a cradle mechanism, and a firing mechanism. The system is designed to operate by purely mechanical means and without power, and is launch speed and launch angle adjustable. The action of the system is such that the arming mechanism may be engaged by a user to apply tension on the cradle mechanism and drive mechanism. The user may then place a ball into the cradle mechanism, and may launch the ball from the system by engaging the firing mechanism. The engaging of the firing mechanism releases the tension in the system, causing the cradle mechanism to accelerate the ball into the air. The entire system is contained within the main body, which is designed to provide an easily moveable, lightweight, and low maintenance solution for achieving such a purpose.

Abstract: A projectile launcher includes an acceleration rail with an accelerator mounted on opposite sides of the rail. Each accelerator includes an elastomeric energy generator having an end that is held stationary, while another end is connected to a string. This string then passes over a series of pulleys and crosses over the rail into the other accelerator. Thus, both accelerators act on the same string. In operation, as the string is pulled back and engaged with the projectile on the acceleration rail, the elastomeric drives are stretched. Also, each series of pulleys effectively causes a velocity multiplication that enhances the momentum of the projectile when it is launched.

Abstract: A ball pitching machine utilizes a leaf spring coupled by linkage to a ball pitching arm. The flexion of the spring can be adjusted by varying the time of operation of a motor driven spring flexion assembly. Upon the selectable spring flexion being achieved, the user then energizes a ball pitching arm for rotation of the arm through a rest position, a ball pick up position and then to a ball release position. During arm rotation, the arm is first coupled to the spring by a linkage assembly such that further rotation of the arm causes the stored energy in the spring to be released to the arm at a position to effect the ball trajectory. The ball trajectory compensates for the various ball speeds so that the ball penetrates the batter's strike zone. This energy transfer accelerates rotation of the arm to a ball release position, the speed of the ball, as perceived by the batter, corresponding in part to the spring flexion and/or ball trajectory as selected by the user.

The piston is linked with a roller of a clutch and ratchet mechanism by a wire. The elastic band is stretched under the tension of its own elasticity between the neutral position and the loaded position by pedaling a clutch and ratchet mechanism.

Abstract: An apparatus for accurately and adjustably throwing a ball to a specific location with variable speed while causing the flight characteristics of the thrown ball to simulate those of a pitched or batted ball. The apparatus includes an elongated planar deck, a flexible pouch for receiving the ball to be thrown, and elastic straps connecting the ends of the pouch to rigid members attached to the planar deck.
