Abstract
Pool game apparatus having homogenous spherical balls of identical size including a cue ball of slightly higher specific gravity than the specific gravity of the object balls; a pool table internally carries a sorting device for the balls having a chute with a deflectable weighing plate pivotable about an axis parallel to the chute and having a trailing edge at an acute angle to the chute; the weighing plate is counterbalanced to remain stationary when an object ball passes over it, but to deflect on passage of the heavier cue ball so that the cue ball is diverted to the side of the path followed by the object balls by a stationary diverter plate adjacent the trailing edge; the chute floor is slanted to one side of the chute axis and is provided with a side support member so that a ball passing onto the weighing plate is supported by the floor and by the side support member. The sorting action is effected not only by the diverter plate, but also by the change in slope of the weighing plate and the force of the side support member on the ball as the plate drops.
