Abstract
Abstract A paint roller cleaning apparatus for paint rollers rotatably carried on a spindle comprising (a) an upright hood having a fluid passing lower opening, and an upper through opening sized to freely pass a paint roller endwise into a cleaning zone within the hood interior, (b) a nozzle carried by the hood to receive cleaning fluid under pressure, the nozzle having an orifice outlet formed to produce a fan shaped spray of fluid directed to spin the roller to effect centrifugal throw-out of removed paint and fluid to drain down the inside of the hood and through the lower opening, and (c) the spray locus being spaced from the upper opening so that the roller extent spinning in that space may be centrifugally freed of fluid prior to withdrawal from the upper opening.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
144 words
In paint roller cleaning apparatus, the roller being rotatable on a spindle, the combination comprising a. an upright hood having a fluid passing lower opening, and an upper through opening sized to freely pass a paint roller endwise into a cleaning zone within the hood interior, b. a nozzle carried by the hood to receive cleaning fluid under pressure, the nozzle having an orifice outlet formed to produce a fan shaped spray of fluid directed at the cleaning zone for impinging on the roller thereby to spin the roller to effect centrifugal throw-out of removed paint and fluid to drain down the inside of the hood and through the lower opening, and c. the spray locus being spaced from the upper opening so that the roller extent spinning in that space may be centrifugally freed of fluid prior to withdrawal from the upper opening.
Claim 2
Dependent Claim
144 words
In paint roller cleaning apparatus, the roller being rotatable on a spindle, the combination comprising a. an upright hood having a fluid passing lower opening, and an upper through opening sized to freely pass a paint roller endwise into a cleaning zone within the hood interior, b. a nozzle carried by the hood to receive cleaning fluid under pressure, the nozzle having an orifice outlet formed to produce a fan shaped spray of fluid directed at the cleaning zone for impinging on the roller thereby to spin the roller to effect centrifugal throw-out of removed paint and fluid to drain down the inside of the hood and through the lower opening, and c. the spray locus being spaced from the upper opening so that the roller extent spinning in that space may be centrifugally freed of fluid prior to withdrawal from the upper opening.
Claim 3
Dependent Claim
21 words
The combination of claim 1 including an internally threaded hose fitting integral with the nozzle and exposed at the hood interior.
Claim 4
Dependent Claim
39 words
The combination of claim 1 wherein the nozzle has a bore defining a principal axis tilted downwardly from horizontal so that the orifice outlet directs the fan spray in a generally vertical plane with spacing below the upper opening.
Claim 5
Dependent Claim
39 words
The combination of claim 3 wherein the hood has a top and side wall, and a sleeve having sections extending on opposite sides of and abutting the side wall, the nozzle projecting through the sleeve and releasably attached thereto.
Claim 6
Dependent Claim
31 words
The combination of claim 3 wherein the hood side wall is inwardly deformed to provide a nozzle mounting extent generally normal to said axis, the nozzle releasably attached to said extent.
Claim 7
Dependent Claim
38 words
The combination of claim 1 wherein the hood has top and side walls, the top wall containing said upper opening and bounded by a rim flange projecting above the levels of said top wall and said upper opening.
