Abstract
Abstract An apparatus and method for cleaning a paint roller cover in which a paint thinning fluid spray is directed at an angle to the paint roller and roller cover surface causing them to rotate. Paint residue on the roller cover surface is removed by the cleansing action of the fluid and the centrifugal force on the roller surface.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
147 words
An apparatus for cleaning a paint roller comprising: an elongated, hollow fluid chamber having an inlet end opening, a distal end, and a plurality of apertures linearly arranged along the elongated axial direction; distal end support member connected perpendicularly to the distal end of said fluid chamber; flexible spring clip coupled to said distal end support; inlet end support member connected perpendicularly to said chamber adjacent said inlet end, said inlet support member having a threaded aperture therethrough; threaded screw rotatably connected through said inlet support member aperture, said screw having a cupped-shaped end for engaging said roller; and water source coupling means connected to said inlet end opening; said chamber, said inlet support member and said distal support member lying substantially in the same plane, and said chamber apertures disposed angularly to said plane containing said chamber, said inlet support member, and said distal support member.
Claim 2
Independent Claim
147 words
An apparatus for cleaning a paint roller comprising: an elongated, hollow fluid chamber having an inlet end opening, a distal end, and a plurality of apertures linearly arranged along the elongated axial direction; distal end support member connected perpendicularly to the distal end of said fluid chamber; flexible spring clip coupled to said distal end support; inlet end support member connected perpendicularly to said chamber adjacent said inlet end, said inlet support member having a threaded aperture therethrough; threaded screw rotatably connected through said inlet support member aperture, said screw having a cupped-shaped end for engaging said roller; and water source coupling means connected to said inlet end opening; said chamber, said inlet support member and said distal support member lying substantially in the same plane, and said chamber apertures disposed angularly to said plane containing said chamber, said inlet support member, and said distal support member.
Claim 3
Dependent Claim
36 words
An apparatus for cleaning a paint roller, as in claim 1, including: elongated tapered spike connected to said chamber, substantially perpendicular to said plane containing said chamber, said inlet support member, and said distal support member.
