Patent ID: 7118486

Claim:
In games employing a cue ball and a plurality of object balls arranged on a table having a playing surface for deployment in a field of play, a method of enhancing the proficiency of a player by assisting said player to visualize the paths necessary for said cue ball to impact an object ball selected from said plurality of object balls at a point image on the outer periphery of said selected object ball to cause said selected object ball to travel to the intended target, comprising: (a) positioning a device for production of laser generated emissions upon said table above and outside of said field of play, said device consisting of a support member and a platform member, said support member spanning across the width of the playing surface and said platform member being adjustably received on said support member, said platform member rotatable in a horizontal plane and for housing a first, second and third laser-light emitting means, said first and third laser-light emitting means being oriented parallel to each other in a downward vertical direction, and spaced one object ball diameter apart, said second light-emitting means when energized projecting a line image and being adjustable in orientation; (b) energizing said first and third laser-light emitting means so that said first laser-light means projects a spot image on the top of said selected object ball whereby said third laser-light emitting means projects a spot image on said playing surface spaced a horizontal distance of one object ball diameter from said spot image on the top of said selected object ball in a direction opposite the location of the intended targets, said support member and platform member being positioned so that said first laser-light emitting means, when energized, projects a spot image on the top of said selected object ball; (c) energizing said second laser-light emitting device; and (d) rotating said platform member so that emission from said second laser-light emitting means projects a line image intersecting said spot image on the top of said selected object ball and said target, whereby the illuminated spot image on the playing surface defines the spot that a cue ball must traverse to impact said selected object ball to travel along said line image to reach its intended target.
