Abstract: This invention pertains to a pool table that consists of 16 pockets rather than the normal six pockets but also includes the normal six pockets. Some of the pockets vary in size. Since the balls are rated as a face value in points and the pockets have a face value rated in points. The multiplying of one another produces a score for every single shot. The highest point scorer wins the game. This is why the invention is titled “Variable Point Pool.

Abstract: A baseball pitching machine is disclosed preferably employing a counterrotating wheel type baseball launch subsystem pitching a series of baseballs and a computer controlled system for selecting the type and percentage of pitches, pitcher and batter characteristics, strike zone areas and other parameters to provide a meaningful batting training session.

A ball support station is provided to support a ball in the path of the ball impact element to be impacted and projected a distance by the arm as it rapidly rotate about the pivot shaft when under the influence of the biasing spring elements.

Abstract: A cue rest for attachment to a suitable support such as the table top includes two opposed jaws with jaw surfaces for engaging opposed sides of the support. The jaws are connected for relative pivotal movement and are spring biased to the clamping position. Each jaw has a manually engageable portion on a side of the pivot axis opposite to the jaw surface and arranged such that the jaws can be moved to the release position by manual squeezing of the manually engageable portions. A generally U-shaped receiving surface is provided on at least one and preferably both of the jaw members, the receiving surface defining an open mouth at an edge of the manually engageable portion opposite to the jaw surfaces for receiving and cradling the cue within the receiving surface.

Abstract: A tethered ball game apparatus for use by two players. The game includes a net supported between two vertical posts. An upright is attached to one of the posts which supports a horizontal arm. The horizontal arm in turn supports an arm which is at right angles to the net. This arm in turn holds a ball tether support arm to which a tethered ball is held. In use, the ball may be struck over the net and the tether slides along the ball tether support arm. In this way the ball never rolls far from the players so that the game may be played by persons even though they may be physically challenged.

Abstract: A method for conducting the game of football is disclosed. In this method, each player is given a designation consisting of a combination of a single letter and certain selected numbers worn on his uniform that directly identifies the player and his assigned position.
