| 20110266371 | Spray gun - A spray gun, which is convertible for use with and without an extension wand, may use the valve mechanism and nozzle attached adjacent to the handle of the gun. When spraying requires the spray to be released away from the gun handle and for spot applications of the spraying liquid, the spraying nozzle is removed and the extension wand or tube is attached to the gun handle. The valve assembly remains in place and another valve assembly and nozzle is provided at the end of the extension furthest away from the handle. A rod is attached to and extends between the valves so that they both move together from closed to open positions responsive to the trigger of the spray gun. When the valves are closed, there is no spraying liquid in the extension. The valving is dripless both with and without the extension. When the trigger is actuated for spraying, spraying liquid under pressure as from a sprayer tank passes through the first valve, the extension tube, and the second valve and exits via the spraying nozzle. The attachment to the first valve may be by a threaded end thereof screwed into a threaded blind hole of the valve of the first valve adjacent the handle. This attachment facilitates disassembly of the extension and rod assembly when only the first valve and the nozzle associated therewith is adapted to be used in spraying. | 11-03-2011 |
