Abstract
Abstract An oscillator roller for a printing press which achieves a superior breakup and distribution of the substances with which it comes into contact, and which comprises an elongated cylinder having one or more spiral bands or raised lands formed along its surface and which extends longitudinally therealong. When more than one spiral band or land is utilized, they are normally found in opposition to each other. The oscillator roller when used in the dampener of an offset printing machine is normally in surface-to-surface contact with one of the form rollers, as referred to, and is operable to distribute the dampening solution evenly over the surface of the form roller prior to its application to the printing plate. The oscillator roller may also be used in like manner in the inking system of a lithographic or conventional printing press to provide substantially even distribution of the ink prior to its application to the printing plate.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
158 words
In a printing press having a printing plate and roll means for selectively applying ink and water to said plate, an oscillator roller mounted in said press and in operative engagement with said roll means, a plurality of spiral bands formed on said oscillator roller, at least two of said bands being opposite in longitudinal progression along the surface of said roller intersecting each other at spaced points along said roller, the ends of said two bands at each end of said roller connecting with each other by means defining a closed loop continuation of said bands adjacent each end of said roller to define a continuous cyclic path by which the ink or water may be selectively moved by one of said two bands in one direction longitudinally along said roller and then through said closed loop continuation of said bands and by the other of said two bands in the opposite direction longitudinally along said roller.
Claim 2
Dependent Claim
158 words

Claim 3
Dependent Claim
25 words
In a printing press as defined in claim 1, and wherein the spiral bands are recessed with respect to the surface of the oscillator roller.
Claim 4
Dependent Claim
28 words
In a printing press as is defined in claim 2 and wherein the depth of the recessed spiral bands is in the range of 0.001 to 0.050 inches.
Claim 5
Dependent Claim
21 words
In a printing press as defined in claim 1 and wherein the spiral bands define interspaced recessed portions on said roller.
Claim 6
Dependent Claim
24 words
In a printing press as defined in claim 4 and wherein the surfaces of the spiral bands are formed of an ink receptive material.
Claim 7
Dependent Claim
25 words
In a printing press as is defined in claim 1 and wherein the surface of the spiral bands are formed of a water receptive material.
Claim 8
Dependent Claim
30 words
In a printing press as is defined in claim 1 and wherein the surfaces of the oscillator roller interspaced between the spiral bands are formed of an ink receptive material.
Claim 9
Dependent Claim
25 words
In a printing press as is defined in claim 1 and wherein the surface of the oscillator roller is formed of a water receptive material.
Claim 10
Dependent Claim
27 words
In a printing press as is defined in claim 1 and wherein the lead angle of the spiral bands is within the range of 60* to 75*.
