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.
A paint applying system comprising an upright paint container having a base wall and an upright wall connected to the base wall and extending upward therefrom, paint disposed in the container in contact with the base wall and the upright wall, a flexible wall in engagement with the paint in the container, a water pressure source means for continuously applying water pressure to the flexible wall in a direction to extend the flexible wall toward the paint within the container, an opening in the upright wall near the base wall of the container for flowing paint out of the container through the opening upon pressurizing of the paint by extension of the flexible wall toward the paint, valve means connected adjacent to the opening externally of the container for controlling the flow of paint outward through the opening and through the valve means, and paint conducting means having a proximal end connected to the valve means for conducting paint outward from the valve means, and paint applying means connected to a distal end of the conducting means for receiving and distributing paint flowing to the paint applying means from the conducting means, the paint applying means including a second valve connected to the distal end of the paint conducting means for controlling flow of paint from the paint conducting means to the paint applying means.
