Abstract
Abstract A hollow cylindrical paint roller cover of absorbent material fits snugly in a cylindrical casing. The hollow center of the cover is closed by appropriate plugs and a cleaning fluid is forced into one end of the casing to flow axially through only the absorbent material and out the other end of the casing. The device is adapted to clean a roller cover having a rigid inner shell or one having no supporting shell and may be made with flexible walls to permit removing the cover from its roller without getting paint on one's hands.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
152 words
In combination, cleaning apparatus and a hollow cylindrical paint roller cover of absorbent material; said cleaning apparatus comprising a generally cylindrical casing, open at one end, of an inner diameter substantially equal to the outer diameter of said paint roller cover, said paint roller cover being in said casing in contact with the wall thereof; a removable closure for said open end, provided with discharge openings communicating with the interior of said casing adjacent the inner periphery thereof; inlet means at the other end of said casing for admitting cleaning fluid; and plug means closing at least the end of said paint roller cover adjacent said other end for preventing flow of cleaning fluid through the hollow center of said roller cover thereby permitting flow of cleaning fluid from said inlet to said discharge openings only axially along the inner peripheral region of said casing and the absorbent material of said cover.
Claim 2
Dependent Claim
152 words
In combination, cleaning apparatus and a hollow cylindrical paint roller cover of absorbent material; said cleaning apparatus comprising a generally cylindrical casing, open at one end, of an inner diameter substantially equal to the outer diameter of said paint roller cover, said paint roller cover being in said casing in contact with the wall thereof; a removable closure for said open end, provided with discharge openings communicating with the interior of said casing adjacent the inner periphery thereof; inlet means at the other end of said casing for admitting cleaning fluid; and plug means closing at least the end of said paint roller cover adjacent said other end for preventing flow of cleaning fluid through the hollow center of said roller cover thereby permitting flow of cleaning fluid from said inlet to said discharge openings only axially along the inner peripheral region of said casing and the absorbent material of said cover.
Claim 3
Dependent Claim
54 words
Cleaning apparatus as defined in claim 1 wherein said roller cover is provided with a substantially rigid hollow inner shell adapted to abut, at one end, with the inner surface of said closure inwardly of said discharge openings; said plug means comprising a plug member adapted to close the other end of said shell.
Claim 4
Dependent Claim
153 words
Cleaning apparatus for a hollow cylindrical paint roller cover of absorbent material comprising: a generally cylindrical casing, open at one end, of an inner diameter substantially equal to the outer diameter of a paint roller cover to be cleaned; a removable closure for said open end, provided with discharge openings communicating with the interior of said casing adjacent the inner periphery thereof; inlet means at the other end of said casing for admitting cleaning fluid; plug means for preventing flow of cleaning fluid through the hollow center of a roller cover in said casing thereby permitting flow of cleaning fluid from said inlet to said discharge openings only axially along the inner periphery region of said casing; said plug means comprising a cylindrical plug carried by said closure and extending into said casing, said cylindrical plug being of a size and shape to fill the inside of a roller cover to be cleaned.
Claim 5
Dependent Claim
153 words
Cleaning apparatus for a hollow cylindrical paint roller cover of absorbent material comprising: a generally cylindrical casing, open at one end, of an inner diameter substantially equal to the outer diameter of a paint roller cover to be cleaned; a removable closure for said open end, provided with discharge openings communicating with the interior of said casing adjacent the inner periphery thereof; inlet means at the other end of said casing for admitting cleaning fluid; plug means for preventing flow of cleaning fluid through the hollow center of a roller cover in said casing thereby permitting flow of cleaning fluid from said inlet to said discharge openings only axially along the inner periphery region of said casing; said plug means comprising a cylindrical plug carried by said closure and extending into said casing, said cylindrical plug being of a size and shape to fill the inside of a roller cover to be cleaned.
Claim 6
Dependent Claim
133 words
Cleaning apparatus for a hollow cylindrical paint roller cover of absorbent material comprising: a generally cylindrical casing, open at one end, of an inner diameter substantially equal to the outer diameter of a paint roller cover to be cleaned; a removable closure for said open end, provided with discharge openings communicating with the interior of said casing adjacent the inner periphery thereof; inlet means at the other end of said casing for admitting cleaning fluid; plug means for preventing flow of cleaning fluid through the hollow center of a roller cover in said casing thereby permitting flow of cleaning fluid from said inlet to said discharge openings only axially along the inner periphery region of said casing; said casing being provided with a resiliently flexible cylindrical side wall having a roughened inner surface.
