end 90 of the handle assembly 60 and pulling the paint regulating needle 70 back and forth there is also an easier way to clean the air brush apparatus 10 then the cleaning method described in u s pat no 5 961 05 issued to kitajima the cleaning method described in this patent involves the tedious task of having to pinch and twist the paint regulating needle 70 instead of simply providing a quick twist and turn to clean the paint regulating needle 70 of this air brush apparatus 10 a cross section of fig2 along line 3 3 is illustrated in fig3 fig3 illustrates the narrow pathway 100 the polygonal shaped aperture 90 and the paint regulating needle 70 in relation to the handle assembly 60 note that the depth of the polygonal aperture 90 is an oval shape and is only deep enough to accommodate the size of the polygonal needle adjusting protrusion 80 the polygonal aperture 90 can be any shape square circle rectangular triangular quadrilateral pentagon hexagonal octagonal or any other polygon as long as it mates with the shape of the corresponding polygonal needle adjusting protrusion 80 the polygonal aperture 90 must be the same approximate shape as the polygonal needle adjusting protrusion 80 the entire handle assembly 60 is one solid piece that has the polygonal aperture 90 and narrow pathway bored out to accommodate the paint regulating needle 70 the polygonal needle adjusting protrusion 80 is also bored out to accommodate the paint regulating needle 70 and allow the paint regulating needle 70 to run through the lever assembly 50 0035 fig4 illustrates a second novel feature of the air brush apparatus 10 which is a novel lever assembly 50 the lever assembly 50 is comprised of a lever handle 150.
