Abstract
Abstract An apparatus is used for applying paint in a container to a surface. The apparatus includes a paint applicator which is movable along the surface to apply paint directed thereto to the surface. Conduit means is provided for directing the paint from the container to the applicator means. A pump having an inlet in communication with the paint in the container and which is operable to continuously draw paint from an open-end container has an outlet which communicates with the conduit means the the pump directs the paint through the conduit means to the applicator. Means is provided for continuously directing at least a part of the paint from the outlet of the pump back to the container so that the paint in the container is continuously mixed in the container while paint is being delivered to the applicator. In addition, the applicator is carried on an extensible or telescoping-type handle and the handle is removable from the applicator without disconnecting the conduit for directing the paint to the applicator.
