Abstract
Abstract A paint roller is cleaned by being slowly rotated while immersed in a body of cleaning liquid within a container. The container is then drained and jets of rinse liquid are directed against the roller while it is rapidly rotated to free it of cleaning liquid. A final rapid rotation of the roller is conducted for spin drying. One side of the container has drain openings for maintaining a cleaning liquid level in the container during the cleaning operation wherein the roller is slowly rotated in a direction advancing its upper marginal portion toward said one side of the container.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
172 words
The method of cleaning a paint roller, said method including: (A) slowly rotating a paint roller about a stationary longitudinal axis with its lower periphery disposed slightly below and parallel to the surface of a body of cleaning liquid in which the lower periphery of the roller is disposed; (B) rapidly rotating the roller free of said cleaning liquid while directing a plurality of side-by-side closely spaced jets of rinse liquid against the roller at points spaced therealong; and (C) thereafter rapidly rotating the roller free of said cleaning liquid and rinse liquid to spin dry the paint roller, said body of cleaning liquid being contained within a container therefor including opposite sides spaced slightly outwardly of the periphery of said roller, one of said sides having cleaning liquid level maintaining drain openings formed therein generally horizontally aligned with the lower marginal portion of said roller, and wherein rotation of said roller in (A) is in a direction of rotation advancing the upper marginal portion of said roller toward said one side.
Claim 2
Independent Claim
172 words
The method of cleaning a paint roller, said method including: (A) slowly rotating a paint roller about a stationary longitudinal axis with its lower periphery disposed slightly below and parallel to the surface of a body of cleaning liquid in which the lower periphery of the roller is disposed; (B) rapidly rotating the roller free of said cleaning liquid while directing a plurality of side-by-side closely spaced jets of rinse liquid against the roller at points spaced therealong; and (C) thereafter rapidly rotating the roller free of said cleaning liquid and rinse liquid to spin dry the paint roller, said body of cleaning liquid being contained within a container therefor including opposite sides spaced slightly outwardly of the periphery of said roller, one of said sides having cleaning liquid level maintaining drain openings formed therein generally horizontally aligned with the lower marginal portion of said roller, and wherein rotation of said roller in (A) is in a direction of rotation advancing the upper marginal portion of said roller toward said one side.
Claim 3
Dependent Claim
22 words
The method of claim 1 wherein the spray jets of rinse liquid of (B) are directed against said roller generally radially thereof.
Claim 4
Dependent Claim
26 words
The method of claim 1 wherein the spray jets of rinse liquid of (B) are directed generally horizontally against the upper peripheral portion of said roller.
Claim 5
Dependent Claim
26 words
The method of claim 1 wherein the spray jets of rinse liquid of (B) are directed generally horizontally against the lower peripheral portion of said roller.
Claim 6
Independent Claim
170 words
The method of cleaning a paint roller, said method including: (A) slowly rotating a paint roller with its lower periphery disposed slightly below and parallel to the surface of a body of soapy water in which the lower periphery of the roller is disposed; (B) rapidly rotating the roller free of said soapy water while directing a plurality of side-by-side closely spaced jets of rinse water against the roller at points spaced therealong; and (C) thereafter rapidly rotating the roller free of said soapy water and said rinse water to spin dry the paint roller, said body of soapy water being contained within a container therefor including opposite sides spaced slightly outwardly of the periphery of said roller, one of said sides having liquid level maintaining drain openings formed therein generally horizontally aligned with the lower marginal portion of said roller, and wherein rotation of said roller in (A) is in a direction of rotation advancing the upper marginal portion of said roller toward said one side of said container.
Claim 7
Independent Claim
170 words
The method of cleaning a paint roller, said method including: (A) slowly rotating a paint roller with its lower periphery disposed slightly below and parallel to the surface of a body of soapy water in which the lower periphery of the roller is disposed; (B) rapidly rotating the roller free of said soapy water while directing a plurality of side-by-side closely spaced jets of rinse water against the roller at points spaced therealong; and (C) thereafter rapidly rotating the roller free of said soapy water and said rinse water to spin dry the paint roller, said body of soapy water being contained within a container therefor including opposite sides spaced slightly outwardly of the periphery of said roller, one of said sides having liquid level maintaining drain openings formed therein generally horizontally aligned with the lower marginal portion of said roller, and wherein rotation of said roller in (A) is in a direction of rotation advancing the upper marginal portion of said roller toward said one side of said container.
