Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
119 words
Apparatus for use with printing machines for moistening moving surfaces such as rolls and webs, comprising a plurality of rotating bodies positioned in side by side relationship for rotation about parallel axes adjacent the surface to be moistened, an elongated housing surrounding said rotating body provided with openings corresponding to each of the rotating bodies opposite said moving surface, and means to supply liquid to the rotating body to be thrown outwardly through said openings in an elongated narrow pattern onto said moving surface, said elongated housing also including interior baffle means positioned between each of said rotating bodies whereby liquid thrown off by each of said bodies issues from the housing through only the corresponding opening provided therein.
Claim 2
Dependent Claim
119 words

Claim 3
Dependent Claim
33 words
The invention defined in claim 1, wherein said rotating bodies include a generally conical surface mounted for rotation about a vertical axis, said surface being provided with a discharge opening for excess liquid.
Claim 4
Dependent Claim
18 words
The invention defined in claim 2, wherein each opening is elongated to produce a fan-shaped discharge of liquid.
Claim 5
Dependent Claim
32 words
The invention defined in claim 3, wherein said housing includes a plate movably mounted with respect to each opening to vary the area thereof to change the size of said fan-shaped discharge.
Claim 6
Dependent Claim
34 words
The invention defined in claim 2, wherein said housing is provided with a discharge outlet for excess liquid trapped inside the housing, including pumping means for recirculating said excess liquid to the rotating body.
Claim 7
Dependent Claim
17 words
The invention defined in claim 5, wherein said means for recirculating said excess liquid includes filter means.
Claim 8
Dependent Claim
26 words
The invention defined in claim 2, wherein said means to supply liquid to the rotating body includes valve means to vary the amount of liquid supplied.
Claim 9
Dependent Claim
54 words
The invention defined in claim 3, wherein said elongated openings in the housing are arranged generally in longitudinal alignment to provide a composite fan-like pattern, said housing also being provided with a discharge opening for excess liquid thrown off by the rotating bodies, and pump means for recirculating excess liquid to said rotating bodies.
Claim 10
Dependent Claim
30 words
The invention defined in claim 8, wherein said housing includes means to adjust the dimensions of said openings to regulate the fan-like pattern of liquid thrown outwardly of the housing.
Claim 11
Dependent Claim
36 words
The invention defined in claim 9, wherein said means to adjust the dimensions of an opening comprises a flat plate positioned against a wall of the housing and slidable to change the size of the opening.
Claim 12
Dependent Claim
35 words
The invention defined in claim 1, wherein said housing is provided with a discharge opening for excess liquid thrown off by said rotating body, and pump means for recirculating said liquid to said rotating body.
Claim 13
Dependent Claim
24 words
The invention defined in claim 11, wherein said pump means includes electro-mechanical valve means to control the supply of liquid to said rotating body.
Claim 14
Dependent Claim
43 words
The invention defined in claim 12, wherein said pump means includes reservoir means, conduit means to return liquid from said discharge to the reservoir means, and a pump having bypass conduit means to supply liquid from the reservoir means to said rotating body.
Claim 15
Dependent Claim
23 words
The invention defined in claim 13, wherein said puMp means includes means to filter liquid supplied by the pump to the rotating body.
Claim 16
Dependent Claim
23 words
The invention defined in claim 14, wherein said pump means includes electro-mechanical valve means to control said liquid supplied to the rotating body.
