Abstract: The present invention relates to a hand-held mechanical analog computer mechanism which is utilized to aid players of billiards and other cue games. The mechanism calculates and displays useful information on aiming, shooting and cue ball deflection. The invention includes a fixed base display as well as a movable dial which is mounted on the fixed base so as to be rotatable with respect to the fixed base in parallel planes around a common axis. Movement of a dial on the mechanism is controlled by a mechanical linking mechanism and rotational positions and angular relationships with respect to scales appearing on the fixed base and movable dial are measured relative to the fixed base.

Abstract: A pool cue alignment device for pocket billiards includes a laser mounted to the shaft of the pool cue. The laser beam is initially directed generally parallel to the pool cue, and at least a portion of such beam strikes the cue ball. A section of a mirror or glass, serving as a beam deflector, is mounted to the pool cue between the laser and the tip of the pool cue for diverting a portion of the laser beam at an acute angle upwardly away from the cue stick. The deflected portion of the laser beam passes over the cue ball generally parallel to the pool table for striking either a numbered object ball or a reflector disposed adjacent a cushion.

Abstract: A bank shot teaching or training device including a pair of arms pivotally supported on a base and positionable relative to teach other by means of indicia formed on the base and the arms such that the angle on the interior face of each arm will be equal relative to an imaginary center line normal to the base and equidistant between the pivot points. The base and arms are positionable on the playing surface of the billiard or pool table with an edge of the base being positionable along the cushion rail beneath the point of impact of a ball with the cushion.

Abstract: A ball game device is formed by an elongated generally upright open end ball receiving tube. In one embodiment the tube has a carom block adjacent its depending end for diverting a ball dropped into the tube in a predetermined lateral direction. In another embodiment the depending end portion of the tube is curved in a lateral ball diverting direction and is supported by a base.

Abstract: A method and apparatus for aiming billiard balls comprising an object ball with a surface coated with an array of colored dots. Adjacent dots are dissimilarly colored to aid in their distinguishment. A desired trajectory is aimed for by first sighting the object ball from a direction opposite a target and selecting a contact dot disposed collinear with that trajectory and furthest from that target. A cue ball or other striking means is then aimed to strike the object ball at the contact dot.

Abstract: The cue ball angle determinator is a small device to be used while playing the game games of pool, billiards or snooker. The purpose of the invention is to determine the exact spot on the rail cushion to strike in order to make an accurate path of travel of the cue ball. This has been accomplished with the cue ball angle determinator by means of adjustable indicators to direct beams of light to the intended balls of action and a marker to mark the point of impact on the rail cushion after this has been established.

Abstract: A cue having a hollow cylindrical handle and a hollow cylindrical shaft with a constant external diameter. A tip member fixed to one end of the shaft and a connector fixed to the other end of the shaft. A butt member fixed to one end of the handle and a connecting member fixed to the other end of the shaft to connect the handle to the shaft. An adjustable weight is located in the hollow handle and a bridge sleeve surrounds the shaft. The bridge sleeve has a bushing at each end with an inner diameter slightly greater than the outer diameter of the shaft so that the shaft can slide through the bridge sleeve to cause a steady movement of the cue.

Abstract: A new and improved apparatus for use with a pool or billiard table includes a stick assembly and arrays of light reflectors attached to the table, in parallel with the respective ball-rebounding surfaces. The stick assembly includes a stick and a laser unit connected to the stick. The laser unit includes a housing which is adjustably connected to a bracket which receives the stick. The stick can also include a spring-loaded ram assembly for striking a ball with a predetermined force that results from an amount of energy stored in a compressed spring. A trigger releases the compressed spring permitting the spring to drive the ram to strike a ball. To employ the apparatus for a straight shot, a first ball, which is to be struck by the stick, a second ball, which is to be struck by the first ball, and a target location, such as a pocket, are selected by a player.
