Abstract
Abstract The invention relates to a rotary newspaper printing press in which there are an inking cylinder which receives ink from an ink fountain, an ink transfer cylinder, a plate cylinder and an impression cylinder. The inking cylinder preferably has an etched surface and it is provided with an ink fountain assembly that includes an ink control blade that accurately controls the thickness and uniformity of the film of ink. The ink transfer cylinder has a resilient pad to which ink is applied by the inking cylinder and which, in turn, applies a uniform film of ink to the plate cylinder. This ink transfer cylinder is provided with a clutch that automatically compensates for swelling of the pad and it is mounted so that it can be moved out of contact with the adjacent cylinders for machining, but without removing it from the press.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
234 words
An improved inking system for a rotary newspaper printing press having a plate cylinder, an impression cylinder and an ink fountain, comprising an inking cylinder in operative relation to the ink fountain to pick up a film of ink on the cylinder''s surface as it rotates partially submerged in the fountain, an ink control blade disposed longitudinally of the inking cylinder adjacent the surface thereof on the side leaving the fountain, said ink control blade having a surface adjacent the inking cylinder that is cylindrical with the radius thereof substantially the same as that of the inking cylinder and said blade being disposed with the upper edge thereof closer to the inking cylinder than the lower edge, means mounting said blade for adjustable movement toward and away from the surface of said inking cylinder and including a pair of micrometer screws located one at each end of the blade to establish the thickness of ink film on the cylinder, means providing a continuous flow of ink through said ink fountain, a single ink transfer cylinder having a resilient cover and mounted for rotation in rolling contact with said inking cylinder and said plate cylinder for transferring ink from said ink cylinder to said plate cylinder, and gear drive means rotating said cylinders and including means maintaining the peripheral speed of said ink transfer cylinder the same as that of the plate and inking cylinders.

Claim 3
Dependent Claim
119 words
The inking system of claim 1 further defined by the underside of the ink control blade being provided with fins extending outwardly of the cylinder and toward a first cylinder end to define first passages therebetween for ink flow, means defining a second passage longitudinally of the cylinder outwardly of said fins from the cylinder and communicating with said first passages, ink outlet means from said fountain at the first end of said cylinder and ink inlet means to said fountain at a second end of said cylinder whereby cylinder rotation pumps ink through said first passages between said fins and along said second passage to establish a continuous ink flow through the fountain between inlet and outlet thereof.
Claim 4
Dependent Claim
161 words
The inking system of claim 1 further defined by said ink fountain being in sealing relation with said ink control blade, means defining a plurality of fins beneath said blade in said fountain in contact with ink in the fountain with said blades extending outwardly of said cylinder and skewed toward a first cylinder end to define first passages therebetween for ink flow as urged by cylinder rotation, means including said blade and said fountain defining a second passage longitudinally of said cylinder outwardly of said fins from said cylinder and communicating with said first passages, ink outlet means from said fountain at the first end of said cylinder and ink inlet means to said fountain at a second end of said cylinder whereby cylinder rotation pumps ink through said first passages between said fins and along said second passage to establish a continuous ink flow through the fountain between inlet and outlet thereof while preventing ink overflow from the fountain.
Claim 5
Dependent Claim
44 words
The inking system of claim 3 further defined by said ink inlet means including quick disconnect means communicating with the bottom of said fountain and said ink outlet means including quick disconnect means communicating with a side of said fountain above said inlet connection.
Claim 6
Dependent Claim
19 words
The inking system of claim 1 further defined by said ink control blade being fixedly mounted in adjustable position.
