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: In a drive for the fluid-distributing roller of a printing press, the roller can be used for distributing either moisture or ink and, in addition to rotating about its axis, is required to be axially reciprocated. The distributing roller coaxially surrounds a drive shaft with which it rotates but with respect to which it can be axially reciprocated. Housed within the roller and surrounding the drive shaft is a step down transmission driven by the drive shaft and driving a cam assembly which is also situated within the distributing roller between the latter and the drive shaft. The cam assembly is driven by the stepdown transmission to provide for the distributing roller lateral movement cycles each of which includes axial movement first in one direction and then in the opposite direction. Each of the lateral movement cycles takes place during a time when the distributing roller and drive shaft both rotate through more than one revolution.
