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.
