Abstract
A mechanism for limiting the rebound of a rapidly moving game ball of a pin ball-type machine amusement apparatus in which the game ball during its initial traverse along a game board surface engages a movable ball rebound arm having operatively associated therewith a rebound spring adapted to be deflected by the rebound arm and temporarily store in the form of potential energy a limited portion of the initial kinetic energy of a rapidly moving game ball. When the rebound spring has stored as much of the initial kinetic energy of the ball as possible, the rebound arm is adapted to continue to move rearwardly and engage a movable weighted arm which is adapted to be moved rearwardly to dissipate the remaining excess kinetic energy of the ball when the weighted arm is moved rearwardly while the rebound arm is being moved forwardly by the potential energy stored in the rebound spring to affect a rebounding of the ball.
