Abstract
Abstract A means, for removing undesired foreign matter from rotating cylindrical surfaces, such as, for example, the blanket of a blanket cylinder in an offset press, comprises a scrub means including a rotatable brush and an absorbent wiper roller. Solvent is applied to the brush so that it is uniformly wetted and a flicker bar is employed which presents a substantially flat inclined surface so that solvent and foreign matter is removed from the bristles of the brush. A tapered drain, generally in connection with a fluid such as water to flush the drain, prevents undue build-up of the matter removed from the brush bristles.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
204 words
An apparatus for cleaning a rotating cylindrical surface containing undesired foreign matter thereon comprising, a scrub means including a rotatable brush roller having an axis and substantially radially extending bristles, means for moving the rotatable brush into and out of contact with the surface being cleaned, means for supplying a predetermined amount of solvent for the foreign matter to the bristles of the brush, means including a wiper roller having an absorbent surface for drying the surface which has been scrubbed, means for moving the wiper roller into and out of contact with the scrubbed surface, a flicker bar including a substantially flat inclined surface positioned to contact the bristles at an angle and for a distance sufficient to allow the individual bristles to flex so as to remove the foreign matter therefrom, the flicker bar being positioned with respect to the brush in such a fashion that substantially all of the foreign matter removed from the bristles is not allowed to return to the brush and, a housing having an upper portion for the wiper roller and a lower portion for the brush roller, the upper portion being hingedly connected to the lower portion so that the brush roller may be readily exposed.
Claim 2
Independent Claim
204 words
An apparatus for cleaning a rotating cylindrical surface containing undesired foreign matter thereon comprising, a scrub means including a rotatable brush roller having an axis and substantially radially extending bristles, means for moving the rotatable brush into and out of contact with the surface being cleaned, means for supplying a predetermined amount of solvent for the foreign matter to the bristles of the brush, means including a wiper roller having an absorbent surface for drying the surface which has been scrubbed, means for moving the wiper roller into and out of contact with the scrubbed surface, a flicker bar including a substantially flat inclined surface positioned to contact the bristles at an angle and for a distance sufficient to allow the individual bristles to flex so as to remove the foreign matter therefrom, the flicker bar being positioned with respect to the brush in such a fashion that substantially all of the foreign matter removed from the bristles is not allowed to return to the brush and, a housing having an upper portion for the wiper roller and a lower portion for the brush roller, the upper portion being hingedly connected to the lower portion so that the brush roller may be readily exposed.
Claim 3
Dependent Claim
45 words
The apparatus of claim 1 wherein the flicker bar is positioned below the axis of the brush roller and said inclined surface is positioned to initially contact the bristles at an angle from about 45° to about 65° with respect to the radially extended bristles.
Claim 4
Dependent Claim
24 words
The apparatus of claim 1 wherein the wiper roller is spring-loaded to bias the roller against the surface being cleaned and is adjustably mounted.
Claim 5
Dependent Claim
95 words
The apparatus of claim 1 wherein the means for supplying solvent includes a solvent tube having a series of spaced holes, a plurality of nozzles positioned to receive the solvent discharging from the solvent tube holes and direct the solvent in the form of individual streams away from the brush bristles, and a baffle positioned to intercept the solvent streams and divert the solvent toward the brush to wet the bristles of the brush, the spacing of the holes and the baffle cooperating to provide a substantially continuous stream of solvent for the brush bristles.
Claim 6
Dependent Claim
23 words
The apparatus of claim 1 wherein the flicker bar is inclined relative to horizontal at an angle from about 25° to about 45°.
Claim 7
Dependent Claim
23 words
The apparatus of claim 1 wherein the flicker bar is inclined relative to horizontal at an angle from about 30° to about 35°.
Claim 8
Dependent Claim
25 words
The apparatus of claim 1 which includes stop means for positioning the brush roller and wiper roller in operative contact with the surface being cleaned.
Claim 9
Dependent Claim
16 words
The apparatus of claim 1 wherein the brush roller is positioned in an open saddle support.
Claim 10
Dependent Claim
59 words
The apparatus of claim 1 wherein the housing includes a drain trough adjacent the brush roller with a downwardly slanting surface from one side of the brush roller to the other, the drain trough being adapted to receive the foreign matter removed from the surface being cleaned and from the bristles of the brush after passing the flicker bar.
Claim 11
Dependent Claim
21 words
The apparatus of claim 9 which includes means for passing fluid down the drain trough to prevent build-up of foreign matter.
