Abstract
Abstract Disclosed is a method and apparatus for cleansing roller-type applicators comprising a container, means for supporting and rotating applicators placed inside the container and means for spraying solvent on the rollers. One of the supporting means has a trough which enables the applicator to be cleaned whether or not it is mounted on a handle assembly. To obtain the desired cleaning action, applicators placed inside the container are sprayed with solvent while being held stationary or while being rotated slowly. Thereafter, the applicators are rotated at a high rate of speed to force the solvent with dissolved contaminants out of the applicators.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
101 words
Apparatus adapted for cleaning unmounted as well as mounted paint roller type applicators comprising: a closeable container; a first support means in said container for engaging a first end of an applicator whether or not said applicator is mounted on a handle assembly; a second support means in said container for engaging a second end of said applicator whether or not said applicator is mounted on a handle assembly; means in the interior of said container for spraying said applicator with solvent; and means for rotating said applicator to cause contaminated solvent to be expelled from said applicator by centrifugal force.

101 words
Apparatus adapted for cleaning unmounted as well as mounted paint roller type applicators comprising: a closeable container; a first support means in said container for engaging a first end of an applicator whether or not said applicator is mounted on a handle assembly; a second support means in said container for engaging a second end of said applicator whether or not said applicator is mounted on a handle assembly; means in the interior of said container for spraying said applicator with solvent; and means for rotating said applicator to cause contaminated solvent to be expelled from said applicator by centrifugal force.
Claim 3
Dependent Claim
19 words
The apparatus of claim 1 wherein said first and second support means are rotatable about a common rotational axis.
Claim 4
Dependent Claim
55 words
The apparatus of claim 2 wherein said first and second support means have the shape of a truncated cone with their respective axes coincident with said common rotational axis and at least one of said truncated cone support means has a trough in its smaller base, adapted to accept the frame of a handle assembly.
