ABSTRACT:
The device consists of a protractor member attached to a board member at the straight edge of the protractor member. It attaches to the rail of the table so that the straight edge of the protractor 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 tops. 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 that 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 protractor member. This creates a straight line from each post to the center point of the straight edge of the protractor member. The existence of both of these straight lines creates an angle from one post to the center point of the straight edge of the protractor member to the other post that can be seen and identified on the face of the protractor member. As the base is moved from side to side on the rail this angle changes. Guide marks on the protractor member give a measurement of each line from the forward center of the protractor member referred to as the ninety degree point. The base can be moved from side to side until both lines are at an equal distance from the ninety degree point. A chalk basin situated on the base, at the center point of the straight edge of the protractor member is now automatically over that point.
