ABSTRACT:
A device for use with artistic sandblasting. The device is a hand-held gun which receives an air/abrasive mixture via a flexible tube which enters the gun through a rear end of the gun. The tube extends through the gun's rear end, between a pinch point and a curved end of an adjustable, spring biased pivotal lever provided internally in the barrel of the gun and attaches to a nozzle removably provided at the front end of the gun. When the trigger is not depressed, the curved end of the lever is biased toward the pinch point, thus squeezing the tube and cutting off flow of the air/abrasive mixture through the gun. The air/abrasive mixture flows through the gun via the tube and out the nozzle when a trigger which is attached to the curved end of the pivotal lever is depressed toward a handle provided on the rear end of the gun and thereby moves the curved end of the lever away from the pinch point, allowing the tube to resume its original unsqueezed configuration.
