  • Patent number: 4320553
    Abstract: A paint roller assembly includes three paint rollers mounted in a mutually parallel relation on a support frame. Two of the rollers are spaced from each other, and are positioned on the frame for rolling engagement with a surface to be coated with paint. A third roller is carried in rolling engagement with the other two rollers for preventing splatter of paint from the rollers, and for distributing paint between the rollers. A handle member is pivotally joined to the support frame by a friction clutch assembly for applying an adjustable frictional force to resist pivoting motion of the handle member.
