ABSTRACT:
A painting system has a container and a flexible wall with a source of pressure on the flexible wall for extending the flexible wall toward the paint and forcing paint through an opening, a valve and a conducting tube into an applicator. A membrane is fitted inside a container, and a cover is placed over the container. Ordinary water pressure from a tap is fed through the hose into the membrane area forcing the membrane toward the paint, and forcing the paint from the container. In one applicator, paint is fed into a hollow tube which is turnable to align openings in a tube wall with distributors which communicate the paint to a plurality of tubes. Paint flows through the selected tubes through an array of openings in paint distributing surfaces. A relatively narrow, pointed surface extends outward from a relatively large circular surface. An auxiliary distributing surface extends perpendicularly to the pointed surface. A sponge roller is provided with a fitted cover and is positioned over a foraminous tube. Extensions on the tube support semi-circular walls at ends of a semi-cylindrical housing. A flange extends around edges of the housing substantially tangentially to the roller surface. Slots in the semi-circular walls and springs urge the flange toward the surface to be painted. An edging device is provided with a truncated conical sponge roller, end plates on the roller and a slideable guard on the remote end of a tube with a spring urging the guard toward the surface to be painted. In a brush modification, paint is flowed to a header and then to a series of tubes which open near tips of bristles.
