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.
