Swing apparatus for an offset press auxiliary print unit and method of using the same

Abstract

A swing apparatus for an offset press auxiliary print unit which includes a swing arm detachable mounted on the auxiliary print unit and a vertical support member upon which the arm will pivot through a generally horizontal plane. The swing arm is rotatable and is operably connected to a pair of lifting tines through a parallelogram linkage so as to lift the auxiliary print unit to disengage it from the main press and then swing it horizontally clear of the press. A crank operates a worm gear and sprocket arrangement to rotate the arm and raise or lower the tines. In a second embodiment, a pair of brackets are affixed to a swing arm, and the entire arm is raised and lowered to lift the auxiliary print unit. An electric motor is used to raise and lower the arm. The method of using this apparatus involves detachably securing the swing arm to the auxiliary print unit, swinging the print unit into operative connection with the main press, disengaging the swing arm from the print unit and swinging it horizontally clear of the press.
