    Abstract: The base frame of an offset printing press consists of two sidewalls made from steel tubing reinforced by ribs and connected by a rigid horizontal tube approximately centered in each sidewall. The diameter of the tube is about one-half of the sidewall height so that it provides good rigidity to the frame. It houses the electric drive motor and the air pump for the press.

    Abstract: A mechanism for laterally orienting paper sheets in a printing machine having a pair of supporting bars and a reciprocable slidable plate located therebetween. The apparatus includes an oscillating shaft on which is freely mounted a body having pressure rollers depending therefrom in contact with the paper on the slidable plate and an end stop engaging the edge of the paper. The shaft also mounts a fixed member adapted to engage one of the supporting bars. As the shafts oscillate the body and member move in opposite relative directions. Means are provided interconnecting the member with the roller and end stop means whereby the roller and end stops are lifted out of contact with the paper during the period of oscillation.
