Abstract

A multiple nozzle paint spraying system two separate banks of spray nozzles. One of the banks is vertically disposed, and the other bank is adjustable to be positioned either vertically or horizontally, the adjustable bank being positioned above the vertical bank. Both banks are supplied by paint from an airless pressurized source, and each individual bank has a shut-off valve to stop the flow of pressurized paint to that respective bank. The entire assembly is mounted on a rollable stand which has a pair of arms extending laterally outward. Wheels or castors are located at the end of the lateral arms which abut the base board or bottom of the wall being painted. During use, the painter merely activates the paint spray and pushes the apparatus along the wall. The lateral arms maintain the spray nozzles at a fixed distance from the wall, and a coat of paint can applied to the wall uniformly and quickly. When painting a wall, the adjustable bank is positioned vertically and both banks are used. When painting a ceiling, the vertical bank is shut off, and the adjustable bank is positioned horizontally to orient the spray nozzles toward the ceiling.
