Abstract
A machine for repeatedly impacting metal castings in order to clean the castings of debris, such as sand, is formed of a wheel-like frame which is rotatably mounted upon a horizontal axle. The frame is divided into four equally spaced apart compartments which provide two pair of opposed compartments. The radially innermost wall of each compartment is formed of a metal plate arranged parallel to the axle so that the plate of the uppermost compartment is horizontal and forms a floor-like support for the casting which is then located in that compartment. Each plate is loosely supported upon springs and has an exposed end portion that extends transversely outwardly of the frame. An impact hammer is arranged to repeatedly apply blows that are directed radially towards the axle against the exposed end portion of the uppermost plate for vibrating the plate and for transmitting the forces of the blows to the casting for loosening debris clinging thereto. An endwise slidable bar extends through the plates of each pair of compartments so that a casting that is moved horizontally into a compartment physically pushes its bar endwise to push the casting in the opposed compartment horizontally o…
