ABSTRACT:
The device is comprised of a shaped member having a straight edge attachable to the rails of a pool table so the the straight edge of the shaped member is directly over the inside edge of the rebound cushion, and can be slid along the rail of the table from side to side. There are two weighted posts with draw twines attached at their top One of the posts is situated on the table at the exact point that the ball is presently at, while the other post is situated on the table at the exact spot where the ball is to end up after it rebounds off the cushion. Each of the twines is drawn to the center point of the straight edge of the shaped member; this created a straight line from each post to a center point of the straight edge of the shaped member. The existence of both these straight lines create an angle from one post to the center point of the straight edge of the shaped member to the other post that can be identified on the face of the shaped member. As the straight edge is moved from side to side on the rail the angle changes. Guide marks on the shaped member gives a measurement of each line from the forward center of the shaped member referred to as the ninety degree point. The shaped member can be moved along the tail until both lines are at an equal distance from the ninety degree point. A hole is placed in the shaped member at the ninety degree point whereby a marker member can be inserted to mark the spot of rebound of a ball from the rail cushion.
