<p>A compressed air spray gun for the application of textured wall finishes has a uniform cylindrical bore receiving an interchangeable barrel, and a trigger mechanism wholly external to the barrel, material to be sprayed being fed laterally into the barrel from a reservoir external to the cylindrical bore, and air being fed through a nozzle extending axially of the barrel. One type of barrel incorporates a nozzle movable axially rearward by the trigger mechanism to project sprayable material through an aperture plate, and another type of barrel is rotatable in the bore so as to meter the passage of particulate material from the reservoir into the bore for projection onto an already applied wall finish.</p> |
