  • Publication number: 20110163185
    Abstract: An air brush is provided with the quick needle pullback mechanism thereby allowing the user to apply quick flushes. This is composed of first pushing down on the trigger to open the air valve and then retracting the needle fully and allowing the needle to be pushed forward by the spring, effectively using the pressured air and paint to clean the nozzle. The distance of the pullback is regulated by a pre-set adjustment knob. A needle chuck and a needle lock perform the function of affixing to the needle, which regulates the paint or media flow. Under normal use, the pre-set adjustment knob defines the maximum paint output by stopping the needle from traveling backward farther than the preset position.

  • Patent number: 7942346
    Abstract: Safety features in and for hose-end sprayer bottles. In a first safety arrangement, there is ensured a more hindered transition of a spool (e.g., product/carrier spool) or adjuster from a first setting to a second setting than from the second setting to the first setting, wherein in the first setting no carrier stream is admitted through the sprayer and in the second setting solely a carrier stream is admitted through the sprayer. In a second safety arrangement, there is arrested displacement of a container interface (e.g., bottle swivel) from a second (essentially advanced) position towards a first (essentially initial) position upon the container interface displacing from the first position to the second position.
