ABSTRACT:
An arrester system for arresting without substantial bounce a moving object, such as the arm of a billet stamper, is constituted by a housing mounting at one end a steel ball which is struck by the moving object. The housing also guides an axially movable steel cylinder which is normally in contact with the steel ball but is driven away from it on impact of the moving object with the ball. The housing further carries a hydraulic or resilient energy absorber which has a piston rod which extends parallel to the movement of the cylinder and which is struck by the cylinder when the latter is driven away from the steel ball. The ball and cylinder form an energy transforming device, the energy of the moving object being transferred via the ball to the cylinder, which in turn transfers the energy to the energy absorber in the direction of the piston rod. Energy transfer is effected without movement of the steel ball and without any substantial bounce of the object.
