Abstract: This invention relates to a novel power lifter for a paper deck of an offset printing press. A paper deck power lifter for an offset printing press comprising: (a) a reversible electric motor connected to a paper deck elevation crankshaft of an offset printing press; (b) an electrically activated solenoid connected to a paper deck catch release of an offset printing press; (c) a manually operated polarity reversing switch connected to the electric motor for determining the direction of electrical current to be delivered to the electrical motor, thereby selecting the direction of rotation of the electric motor; (d) a manually activated electrical variable speed switch electrically connected to the electric motor to enable manual control of the speed of rotation of the electric motor.

Abstract: This invention pertains to a novel wagon which holds a stack of printing paper. More particularly, this invention relates to a paper stack holding truck (pre-loader) which assists in efficiently loading paper into a offset printing press, and thereby reduces press down time. A paper pre-loader for an offset printing press compressing: (a) a wagon frame; (b) at least three wheels rotatably mounted to the underside of the wagon frame; (c) a pair of adjustable width paper guides extending vertically upwardly from the wagon frame; and (d) a paper board for enabling a stack of paper to be readily moved from the top of the wagon frame onto a paper deck of an offset printing press.
