Abstract: A system and method for pitching balls, particularly round balls such as volleyballs. The system and method are flexibly designed to simulate different types of pitches including but not limited to setting, blocking, bumping, shooting, dinking, passing, tipping, digging, serving, killing and spiking. A stable base frame is configured with an integrated operator stand. A rack bar is affixed to a front portion of the frame at an inclined angle. Three wheels are mounted on an adjustable throwing head, each wheel being powered by a motor that is adjusted independently so that the relative speed of the wheels imparts different spin to a ball that is launched from the throwing head. The throwing head can be adjusted up and down on the rack bar to be as high as a jump serve release point or as low as a at floor level to simulate a dig. The apparatus is portable and fits through standard gymnasium doors.

Abstract: A system and method to pitch balls using one powered wheel. The system and method comprise a single powered wheel and at least two pinch pads configured with an aperture between them to allow a player to see the ball throughout the length of its descent into the aperture prior to being pitched.

Abstract: A system and method for pitching balls, particularly footballs and other football-shaped balls. The system and method are flexibly designed to simulate different types of pitches including but not limited to passes, punts, kick-offs and snaps. A cradle for use in the system and method holds the ball in any one of a number of positions such that when it is fed into the system, the ball is propelled to simulate a different type of pitch. The apparatus and system for pitching balls includes a support for a ball throwing head, two opposing variable speed motor powered wheels that can be tilted in relation to each other to control the spin and distance, a slide configured to present the ball on the cradle into the wheels at different angles to provide right or left handed spirals and end over end pitches, and adjustments for height and horizontal pivot. A removable throwing head allows balls to be pitched from different heights from ground level to an upright arm motion to simulate different types of pitches.

Abstract: A system and method to pitch balls with a fine adjustment subsystem. The system and method allow an operator to make fine adjustments to the horizontal trajectory of a ball as it passes in front of the hitter. The system includes a throwing head with at least one wheel powered by a motor and a control panel with an adjustment for each motor so that speed and spin imparted to the ball can be changed. This invention further includes a method for pitching practice balls wherein the balls are delivered to a person in need of hitting practice. The fine adjustment subsystem permits an operator to quickly and easily change the horizontal positioning of the balls that are thrown to vary the pitches as a batter practices.

Abstract: A system and method for pitching balls, particularly round balls such as soccer balls. The system and method are flexibly designed to simulate different types of pitches including but not limited to kicks, throws, and headers. A main frame has a frame with a front panel, a rear panel and a top panel. A tubular chute is rotatably mounted in the interior portion of the main frame with a set of bearings. A pair of opposing ball throwing wheels are fitted to the rotatable tubular chute for launching the ball from the chute. Each wheel is driven by a variable speed motor that is controlled by a variable switch mounted to the main frame. A pair of caddy wheels is attached to the main frame for portability of the apparatus, along with a rear support having an adjustable extension to vary the height and angle of the rotatable tubular chute to adjust the trajectory of the ball. A ball feed chute is mounted to the main frame onto which balls are loaded to be pitched.

Abstract: Practice balls may be presented to a person in need of hitting practice by using an apparatus for pitching practice balls that includes a support for a ball propelling head, high enough to raise the head to the approximate height of a pitcher's arm when he releases a pitched ball, three variable speed motor powered wheels forming a ball propelling chute to propel a ball dropped through the chute attached to the ball propelling head, the three wheels forming a chute through which the ball to be thrown is visible, and the three variable speed motor powered wheels attached to a motor plate held within and attached to a pivotable frame; a control panel attached to the support providing access to one speed control for each motor driving a ball propelling head; and at least one front wheel guard plate in front of at least one ball propelling head of sufficient strength to provide protection from pieces of the wheels if the at least one wheels should disintegrate.
