Abstract
A nozzle adapter is removably mounted on the end of a liquid spray gun to provide a variety of spray patterns and to reduce or eliminate the atomization of the spray liquid. The nozzle adapter is formed by a liquid material discharge member which is removably mounted on the spray gun and an outer pressurized air adjustment member which is removably adjustably mounted on the discharge member. A cone-shaped nozzle of the discharge member projects outwardly through an air passageway formed in a front wall of the air adjustment member. A tubular stream of pressurized air is projected outwardly through the air passageway and surrounds a stream of liquid discharged through an opening in the nozzle tip. Adjustment of the tubular air pattern provides for various liquid spray patterns and varying amounts of atomization of the discharged liquid. The discharge member may alternatively be mounted on a spray gun without the air adjustment member mounted thereon. The nozzle of the discharge member extends outwardly from an annular wall formed with a plurality of air ports in a circular arrangement about the base of the nozzle and rearwardly of the liquid discharge opening in the nozzle tip. A thin stream of liquid emitted from the discharge opening is carried by the spaced stream of pressurized air from the air ports for deposit on an adjacent surface to provide a non-atomizing decorative spray pattern. No known prior art nozzle adapter achieves such a variety of spray patterns in as simple a manner.
