ABSTRACT:
An apparatus for removing a dead-head from a casting comprises a device for exerting on the dead-head or the casting a force which does not pass through the joining neck between the dead-head and the casting. This force generates bending moments which cause the dead-head and casting to break apart at the neck. The force can be applied by a fluid-actuated cylinder which acts on the dead-head or casting either directly or via a linkage comprising one or more levers.
