Description
IFEM. Q, N932. w, REES DEVICE FOR TREATING ARTICLES OF FURNITURE Filed Aug. 30, 1950 "r lllllzllllllllllm Patented Feb. 9, 1932` UNITED STATES WILLIAM BEES, OF ST. LOUIS, MISSOURI DEVICE FOR TBEATING ARTICLES OF FURNITURE Application iled August 30, 193i). Serial No. 478,994.
My invention has relation to improvements in devices for treating articles of furniture and it consists in the novel features of construction more fully set forth in the specitication and pointed out in the claim.
More specifically the device comprises a spray gun and a spray nozzle associated therewith, the former embodying 'features tor cooperation with the nozzle to produce le an etticient and simple device :for penetrating mattresses or other padded articles and injecting a suitable liquid in a highly atomized condition thereinto for the purpose of destroying bacteria, preventing the nesting I therein of insects.
Further object'ozt the invention is to provide a spray nozzle in the shape of a needle that may be inserted into the padding of an article without injury thereto and that is provided with a mixing chamber for air and the liquid insecticide so that the latter discharges from the outlet apertures in a highly atomized condition and the insecticide will be caused to thoroughly impregnate the pad- -35 ding without noticeably saturating the same. Further and other advantages will be better apparent from a detailed description of the invention in connection with the' accompanying drawings, in which-- Fig. 1 is a side elevation of my improved device with parts shown in section; Fig. 2 is an enlarged longitudinal section through the spray needle; and Fig. 3 is a further eny larged section through the spray needle with 3: a art thereof broken away.
eferring to the drawings showing a preerred embodiment of the invention, 1 represents a suitable container for the insecticide having a screw top 2 into the upper reduced portion 3 of which is screwed a stem 4 of a hand pump 5. A tubular housing 6 is screwed into the cap portion 3 opposite the pump stem 4 and a liquid ejector tube 7 traverses the tubular housing 6 and is bent so as to extend downwardly into the container 1. The outer end of the tubularhousing 6 is threaded to receive a coupling member e in a soc et of the extended portion 1.1 of
Still another advantage is obtained by having the point 15 as a solid member, that is, the inner end 17 of the point furnishes an 70 abutment wall against which the mixture of air and liquid impinges to assist in the operation of breaking up particles of liquid into a finely atomized condition. The mixture of air and fluid that enters the chamber` 14 of the spray nozzle discharges therefrom through three radially disposed openings 18 spaced a short distance from the inner end 17 of point 15. I have found that the sum of the areas of the openings 18 should be ap- 80 proXima-tely equal tothe area of the port 13 so as to restrict the amount of air ejected through these openings with the liquid insecticlde. I wish to avoid any degree of vaporization of the insecticide. as I have found that the best results are obtained by injecting the insecticide in a finely atomized condition. In other words, the liquid particles of insecticide are more effective in destroying pests than 'vaporized insecticides 9 The advantage of the wall 17 immediately beyond the openings 18 is that the impingement of theliquid insecticide against this wall just before the insecticide' discharges from the openings 18 will operate to break 95 thecolumn of liquid into very small globules and insure its leaving thesaid-openings in a highly atomized condition. t
I have found in practice a spray'nozzle constructed as just described is very. effective 10 treating upholstered furniture, cushions, etc. to revent their becoming infested with mo tow bugs, or other vermin. Then, too, the spray is in such a highly divided condition that there is no danger of staining the surface of the articles by an exssive discharge of liquid. v
Having described my invention, I claim: In combination with a liquid ejector tube, a spray nozzle comprising a coupling member and a nozzle tube of substantially uniform bore ixed to said couplin member, said coupling member having a soc et into which the ejector tube is received and a constricted passageway between the nozzle tube and socket and a solid point element fixed' at the end of the nozzle tube opposite to the coupling element, said nozzle tube having radial apertures adjacent to the point element, and said ejector tube havin a serrated edge enveloping the constrict passageway.
In testimony whereof I hereunto ax, my l signature.
WILLIAM BEES.
