through the body f 3 axially .o'f gtne borefilB Lis .a In using the device, the fitting .14 is connected needle valvefi lhaving a conical tipseatedgin. the bye suitable conduit to a source ofcompressetl conical fitting tip 23, spring means, notshown, air, and the fitting I1 is connected by a suitable being provided in the handle 12 acting on the conduit to a source of insecticide or other fluid to rear end portion of the needle valve and biasing be sprayed, the latter fluid being likewise under said plurality of spaced longitudinally extending ports of said sleeve, an end wall provided with a plurality of spaced apertures on the other end of said second tube, the other end of said first named tube being spaced from said end wall of said second named tube, and a second end wall provided with a centrally disposed aperture on the other end of said first named tube and spacedly the passage |5 into the chamber 20 and through the apertured flange 29 and passages 3| into the space between the inner tube 40 and the outer tube 35. The air flows past the lumps of solder 43 into the mixingchamber 4| and mixes violent- 13! with the jet of liquid emerging from opening 42 and creates a mixture of air and liquid which emerges from the openings 45 in the form of a fine spray or fog. In applying the spray or fog, an opening which need only belarge enough to secured to the adjacent portion of said second named tube, said second and first named end walls and the adjacent portion of said second named receive the tip 35 is made in the inner element of the wall which is to be treated, the curved tip 35 being inserted through said opening and being held so that the spray. or fog emerging from the apertures 45 may be directed in any desired direction parallel to the wall. It is thus possible, by rotating the gun around the axis defined by the rear portion of the tip 35, to distribute the fog or spray substantially throughout the wall interior in a uniform manner in all directions. By
repeating this procedure at difierent locations in the wall, the entire wall may be thus treated with only a small amount of insecticide being required to completely fill the inside of the wall with a fog of the mixture. After the treatment has been concluded at each aperture in the wall, said aperture may be plugged up in any suitable manner, and inasmuch as only a small aperture is required, it is a relatively simple matter to hide the aperture. I
While a specific embodiment of an improved spray gun for distributing a fog of insecticide or the like inside building walls has been disclosed in the foregoing description, it will be understood that various modifications within the spirit of the invention may occur to those skilled in the art. Therefore, it is intended that no limitations be placed on the invention except as defined by the scope of the appended claims.
What is claimed is:' 1 1. A spray gun comprising a gun body having a first passage fo r air under pressure and a second passage for liquid spaced from said first passage, a discharge nozzle connected to one end of said second-passage, a sleeve having one end arranged in confronting relation with respect to one endv of said gun body adjacent said nozzle, a cylin-, drical flange on the confronting end of said sleeve embracingly surrounding said nozzle'and secured tdsaid one end of said gun body, said flange bemg spaced from said nozzle to provide a space therebetween, said space being in communication with the adjacent one end of said first passage,
there being a plurality of spaced longitudinally extending port extending inwardly from the other endof said sleeve' and terminating in and in communication with said space, a longitudinal tube having one end extending into the other end 'of said sleeve and embracing said discharge nozzle, a second longitudinal tube circumposed about and spaced from said first named tube and having one end fixedly secured to the other end of said sleeve, the space between said first and second named tubes being in communication with tube forming a mixing chamber for the liquid discharge through the central aperture of said second end wall and the air discharged through the spaced securement of said second end wall.
2. A spray gun comprising a gun body having a first passage for air under pressure and a second passage for liquid spaced from said first passage, a discharge nozzle connected to one end of said second passage, a sleeve having one end arranged in confronting relation with respect to one end of said gun body adjacent said nozzle, a cylindrical flange on the confronting end of said sleeve embracingly surrounding said nozzle and secured to said one end of said gun body, said flange being spaced from said nozzle to provide a space therebetween, said space being in com.- munication with the adjacent one end of said first passage, there being a plurality of spaced longitudinally extending ports extending inwardly from the other end of said sleeve and termin ating in and in communication with said space, a longitudinal tube having one end extending into the other end of said sleeve and embracing said discharge nozzle, a second longitudinal tube circumposed about and spaced from said first named tube, an outwardly extending flange on one end of said second tube and having one face abutting against the other end of said sleeve, 9. coupling nut bearing against the other face of said outwardly extending flange and embracingly secured to the other end of said sleeve, the space between said first and second named tubes being in communication with said plurality ofspaced longitudinally extending ports of said sleeve, an end wall provided with a plurality of spaced apertures on the other end of said tube, the other end of said first named tube being spaced from said end wall of said second named tube, and a second end wall provided with a centrally disposed aperture on the other end of said first named tube and spacedly secured to the adjacent portion of said second named tube, said second and first named end walls and the adjacent portion of said second named tube forming a. mixing chamber for the liquid discharge through the central aperture of said second end wall and the air discharged through the spaced securement of said second end wall. 1
