Abstract
A convergent type of spray gun is made portable by miniaturizing the components with the addition of a double tube, fluid tip and air cap for defining the discharge nozzle for the liquid resin and atomizing air. The dry powdered nozzle is likewise miniaturized and is adapted to fit over the double tube, fluid tip and air cap arrangement by including a sleeve disposed therebetween. The main body is configured in either an L-shape or straight-through configuration. Although the component parts are miniaturized, the spray gun is capable of flowing coating mixture at the same rate as the larger version convergent spray gun.
