(Cl. 101-181) This invention relates to improvements in nism are driven from gear l0 receiving its power printing presses and is particularly directed to from any suitable source. This gear l0 meshes the provision of a construction wherein the ink ” with gears II and H to drive printing rollers l3‘ ing mechanism is movable as a unit toward and and I4, respectively. The rollers above the roller 5 away from the printing mechanism. ' ' Itis an object of the present invention to pro vide a- printing press of the character indicated ‘it (not shown in the drawing) are driven by 5 suitable gearing from the gear H as will be obvi ous. entirely separated from the printing mechanism 10 so as to provide access to the printing-plates and wherein the two mechanisms can be separated to a lesser degree to disengage the inking rollers from the printing rollers without interrupting the drive for the inking mechanism so that the 15 vibratingx rollers may continue to ink the inking rollers. ‘ - . . ' Mounted on the shaft of the gear H but out side of the frame of the printing mechanism is a gear 20 adapted to mesh with a pinion 2| mounted 10 on shaft 22 outside of the inking mechanism wherein the inking mechanism as a unit can be frame. Gear 24 mounted on the shaft of gear i2 also on the outside of the frame of the printing mechanism is adapted to engage pinion ' 25 mounted on a shaft 26 outside of the frame -of the 15 - inking mechanism. The pinions 2| and 25 are From the following description and the accom-v A not in mesh with their respective gears 2|! and panying drawing other objects of my invention 243U at the same time, as will be hereinafter pointed 7 will be manifest and the invention more clearly out. an understood.

Fig. 5 is a view taken on line 5-5 ‘of Fig. 1. In addition to moving the inking mechanism 20 away from the printing mechanism to provide access between the two mechanisms thereby dis connecting the drive entirely as above described, it is also desired to move the inking mechanism away to a lesser extent when no printing is tak- 25 ing place, but to‘retain the driving connection between the two. In this case, the inking rollers are moved out of contact with the printing rollers‘ l3 and H, but the inking of the inking rollers will continue. In other words, they vibrating rollers 30 will continue to rub and spread ink on the ink-' Referring to the drawing in detail, I designates ' ing rollers to secure the proper density of the the base of the press which supports a frame 2 color which is very desirable in color printing.
